Introduction: Magic Color Changing Water

Magic Color Changing Water

It's Magic!

Water changing from CLEAR to BRIGHT PINK and back to CLEAR!

Well, not really magic, but chemistry; and still amazing!

This is a very visual demonstration using an indicator to identify the pH of a solution; as an acid or a base.

First the water is made to have a basic pH by adding Sodium Carbonate (Na2 CO3). Not to be confused with Sodium Bicarbonate which is Baking Soda.

Then by adding the indicating solution, Phenolphthalein Solution (C20 H14 O4), it turns the water a striking pink color indicating that the solution has a basic pH.

Finally the water is transformed back to clear by adding vinegar (Dilute Acetic Acid CH3 CO OH) to bring the solution back to a neutral pH, and the pink indicator disappears.

The color change takes place almost instantaneously - which is amazing to watch!

It's a very fun demo to perform.

This presentation has multiple uses - As a magic trick, as a purely scientific demonstration, as an object lesson, as a metaphor for damage and restoration or sin and repentance, and many others. Or just for plain fun!!!!

You can see more info on phenolphthalein on Wikipedia .

WARNING: Do NOT drink the water. Keep out of the reach of children. Follow all warnings and cautions on chemicals.

 P.S. If you find the Instructables I post interesting please click the "Follow" button above. Thanks!

Step 1: Materials

Materials

To perform this demonstration you will need:

Water (H2O, aka Dihydrogen Monoxide ;-)

Phenolphthalein Solution (C20 H14 O4)*

Sodium Carbonate (Na2 CO3)*

. [Sodium Carbonate. Not to be confused with Sodium Bicarbonate which is Baking Soda.]

Dilute Acetic Acid (CH3 CO OH) (White Vinegar)

Tall Large Glass Container (Cylindrical flower vase)

Bottles (2 liter, small squat 237 ml (8 fl oz), small vial ~2ml (0.07 fl oz)

*Easily purchased online.

Also, some chemistry sets do have all the chemicals needed. Years ago I purchased a 'toy' chemistry set that had 400 'experiments' that included color changing experiments and had what was noted here.

WARNING: Do NOT drink the water used in this demonstration. Keep out of the reach of children. Follow all warnings and cautions on chemicals.

Phenolphthalein Solution (C20 H14 O4) CAUTION Contains 50% Ethyl Alcohol. DO NOT INGEST. EYE IRRITANT. For eyes, wash with water. In case of accident seek professional medical attention.

Sodium Carbonate (Na2 CO3) CAUTION IRRITANT. HARMFUL IF SWALLOWED. Avoid contact with eyes and prolonged contact with skin. In case of eye contact flush freely with water. If swallowed, give water, see professional medical attention.

Step 2: Prepare Liquids

Prepare Liquids

Add Sodium Carbonate (Na2 CO3) to the water ahead of time. About 1g (0.03 oz) to 1 liter of water (~1 quart). This gives the water a basic pH to start.

I found a 2 liter bottle half full convenient.

Place about 2 ml (<1/2 tsp) Phenolphthalein Solution (C20 H14 O4), the pH indicator, in a small vial.

Fill the small water bottle with 230 ml (~8 fl oz.) of white vinegar, which will be used to take the water back to neutral, and clear, from the basic pH.

Step 3: Make the Magic Happen

Make the Magic Happen

Make the Magic happen by going through the steps noted below. Be sure to embellish each step as appropriate for your application.... I'm sure there is a lot of dialog that would go along with each step if this was being used as a magic trick!

1. Fill the glass about 3/4 full with water (basic pH, from Sodium Carbonate added previously).

2. Pour the Phenolphthalein Solution from the vial into the Glass Container. The water will turn shocking pink as the Phenolphthalein Solution enters. It will look like you are pouring pink liquid into the water.

3. Stir the water to evenly distribute the pink color (indicator).

4. Admire the brilliant pink!

5. Pour the small bottle full of white vinegar into the glass (brings pH back to neutral). The water will start turning clear immediately.

6. Stir if needed.

7. Admire the Magic of a clear glass of water!

Talk up your demonstration!

Enjoy the Magic of Chemistry!

Water Experiments for Kids That Are a Big Hit in the Classroom

Hero image

Written by Cassie (Teach Starter)

Are you teaching your students about water in your science classes? It’s time to pull out the water activities for kids that will wow them … while also helping your students learn about density, salinity, mass, and a whole lot more.

The teachers on the Teach Starter team have put together some water experiments for kids that can easily be done in a classroom with little prep — and without a ton of expensive items to buy. These water science activities are also easy for kids to recreate at home if they want to show off their newfound knowledge.

Water Experiments for Kids

Let me add, it’s always a great idea to try these experiments at home before you do them with your class for the first time. Just to make sure you know any little tweaks that are needed to illustrate the concepts you are exploring!

Understanding the Effects of Water Temperature

Use this water experiment for kids to explore the concept of temperature and its effect on the speed that molecules move. This science experiment for kids will quickly illustrate how molecules move faster in hot temperatures and slower in cold temperatures.

You will need:

  • Room temperature water
  • 3 stopwatches (or phones)

three glasses with different temperature water

How to do this water science activity:

  • Fill one glass with cold water, one with room temperature water, and one with hot water. (It is best to prepare the cold water and room temperature water earlier. Leave one glass in the refrigerator for at least an hour prior to the experiment. Leave another glass sitting out for at least an hour too, as if the water in your pipes is a bit cold this will reduce the efficacy of the experiment.)
  • Place a stopwatch in front of each glass.
  • Fill the dropper with food dye.
  • Drop 2-3 drops of food dye in each of the glasses and observe how the food dye behaves in each different water temperature.
  • Start the stopwatches when the food dye is dropped.
  • Stop each watch as the food dye has mixed completely with the water.

use cold water, warm water and hot water with food dye to illustrate how molecules move in different temperatures

Your students will be able to see how the food dye mixes quickly with the hot water because the molecules are moving quickly. It takes longer to mix in the room temperature water as the molecules move slower, and in the cold water, the food dye will take the longest to mix as the molecules move at the slowest speed of all three samples.

Eventually, the food dye will mix through the water in all three glasses. Students can predict how long each will take and then record the final times on each of the stopwatches.

Salt Water Density Experiments

Use this experiment to introduce the concepts of density, mass, salinity, and buoyancy.

In this experiment, you and your students will use one bowl of fresh water and one bowl of salt water to explore how salinity affects the buoyancy of different foods. For example, what happens when you put eggs in a bowl of fresh water and a bowl of salt water?

To get started, download and print the Salt Water Density Experiment resource , and prepare the materials described.

Egg Water Density experiment

Challenge your students to guess whether they will have the same or different results if they try this same experiment using potatoes in place of the eggs.

potato water density experiment

This experiment also uses food dye to explore how liquid molecules behave differently in fresh water and saltwater.

Salt water density experiment with food dye

When your students understand how water behaves differently depending on its density, they can begin to understand more about topics such as:

  • the effects of freshwater runoff from melted sea ice in the Antarctic
  • how different parts of the ocean have different levels of salinity
  • why objects that would normally sink (like people) can float in bodies of water with high salinity like the Dead Sea in the Middle East and the Great Salt Lake in the United States
  • how salinity affects the different layers of the ocean and the types of marine life that can live in each layer.

Refraction of Light Science Activity

This water experiment for kids is incredibly simple to set up, and it will help your students better understand refraction, the change of direction of light waves, when they hit water.

All you need is:

  • A Glass of water

Refraction of Light Science Activity

Draw something on a piece of paper. An arrow is a great visual to start this science activity as it is obvious what happens when you put the glass of water in front of the drawn arrow. But you don’t have to limit it to arrows. Get creative and draw anything you would like to see through the glass.

Refraction of Light Science Activity

When the light is passing through the glass of water, it refracts or bends. The glass of water acts as a cylindrical convex lens and produces an inverted image.

Create a fair test by changing one variable. What happens if you change the size of the glass? Or what if you change the liquid variable? Does it change the result?

Teach your students more about reflection and refraction with these resources:

[resource:4701421][resource:2674282]

Create a Lava Lamp Science Activity

No need to head out to buy a lava lamp. You can make your own “lamp” with this fun water activity for kids that teaches about the changes of density as gas is added to or taken away from the water.

  • Two glasses
  • Vegetable oil
  • Food coloring
  • Alka-Seltzer tablets

Create a Lava Lamp Science Activity

Firstly, mix half a cup of water with some drops of food coloring. You can make two different batches with different colors if you wish to make more than one lava lamp.

Then, fill a glass with vegetable oil (3/4 full). Pour some of the colored mixture into the oil, being careful not to fill the glass too much.

Add one Alka-Seltzer tablet, and watch the chemical reaction…

Create a Lava Lamp Science Activity

The Alka-seltzer tablets react with the water to produce carbon dioxide gas bubbles in this fun water activity! These stick to the water droplets. The water/gas combo is less dense than the oil, so they rise to the top of the glass!

Make this a fair test by changing the amount of Alka-seltzer added. In one glass you can add one tablet, another can have two tablets, and another can have three. What happens when you change up the water experiment?

Moving Water Experiment

This water activity for kids explores water movement and helps kids understand capillary action. It does take a couple of hours for the results to finalize, so it’s best an experiment that you set and forget, checking back in throughout the day with your class. Perhaps take a picture every half hour to monitor your progress!

Aim: To investigate the movement of water when it has paper towel placed in it.

  • A measuring cup
  • 4 pieces of paper towel
  • Red, blue and yellow food dye
  • 5  clear drinking cups/glasses (jars work well too!)
  • water – enough to pour equal amounts into 3 of the cups
  • 3  mixing spoons
  • Line up 5 cups. Fill cups number 1, 3, and 5 with equal amounts of water.
  • Place equal drops of food dye into each cup of water – place blue into one cup, red into another, and yellow into the final cup. Mix each cup thoroughly with a new spoon to prevent cross-contamination.
  • Place a scrunched piece of paper towel so that it creates a bridge between each cup in the line. The paper towel must be quite deep in the water in each cup.
  • Watch what happens over the next few hours and record your results!

This is similar to the way that the roots of a tree pull water up and out of the ground. You can observe the movement and direction of the water by watching the water move up the paper towel, and observing the empty cups filling with a ‘new’ colored water as the two primary colors on either side mix together.

plastic cups filled with rainbow colored liquids and paper towels sit on a table beside food coloring bottles and experiment instructions

Possible questions to ask:

  • What will the food dye from one cup do when it mixes with the dye from another cup?
  • Why do you think the water didn’t move backward once the empty cups started to fill up?
  • Why do you think the water stopped moving once the cups leveled out?

Check out this fun capillary action water activity for kids using flowers or this one using paper towels and capillary action to make roses that the kids can bring home to gift to someone they love.

Alive Water

Water experiment by dr. masaru emoto.

change water experiment

Dr. Emoto Believed, “ Water is the mirror that can show us what we cannot see. It is the blueprint for our reality, which can change with a single, positive thought. All it takes is faith if you’re open to it. ” Though for many of us, it is difficult to believe in the unseen, interestingly, there are water experiments and observations that explain water’s magnificent nature. In this article, we discuss Dr. Masaru Emoto, specifically water experiments by Dr. Emoto, and the concept of water’s consciousness. Understanding the consciousness of water will help you see the benefits water has to offer to you, and just how you can turn regular water into something more.

By understanding the water experiment done by Dr. Emoto, we will be able to see how water has phenomenal benefits depending on its surroundings. We will further delve into a way to treat water in order to maximize the benefits of drinking water, bringing more vitality to your water. All this through the teachings and findings of Dr. Masaru Emoto.

Content Navigation:

Who is dr. masaru emoto, how does the water experiment by dr emoto impact you, water consciousness with the vortex water revitalizer™.

Dr. Masaru Emoto was a Japanese water scientist, born in 1943 in Yokohama, Japan. He was an internationally renowned Japanese researcher, author, scientist, and businessman. He graduated from Yokohama Municipal University’s department of humanities and sciences, majoring in international relations. Additionally, he received certification as a Doctor of Alternative Medicine from the Open International University.

The New York Times bestseller “The Hidden Messages in Water” is an example of Dr. Emoto’s phenomenal work. Through his writings, he made millions of people realize that water is much more than just an H2O molecule. Dr. Masaru Emoto revolutionized the way we think about water, and its impact on our health, lives, and the environment. He was undoubtedly a genius of his time,  one of the first of those who put forth the idea of water’s consciousness.

One of the boldest claims of Dr. Emoto that he managed to prove scientifically was that water is sensitive to our thoughts, words, and feelings. Because of this, water can change its molecular structure according to the environment it is introduced to. For instance, Dr. Masaru Emoto argued that prayer and heavy metal music could influence the molecular structure of water differently. 

In his book, the Japanese water scientist and author says: “Water records information, and while circulating throughout the earth distributes information. This water sent from the universe is full of the information of life.”Dr. Emoto passed away on October 17, 2014 , but his work is still alive, spiking the interest of millions and encouraging scientists to research the concept of water’s consciousness further.

What Impacts the Water? Water Experiment by Dr Masaru

According to Dr. Masaru’s theory of water consciousness, water can respond to human emotions, thoughts, words, and even written messages.

The water can pick up the vibrations as a result of certain emotions and change its structure accordingly. For instance,  when you say the word “Hope” to water and prepare the frozen crystals from this water, you will observe the creation of beautiful symmetry in the crystals.

dr. masaru emoto photography

This can lead to the conclusion that drinking water with positive emotions such as love can have a positive effect on human health. Similarly, when you expose water to negative feelings such as hate, consuming it can be potentially harmful to your body.

As we see, emotions can alter the water’s form but can human thoughts also lead to an impact? The short answer – yes. Dr. Masaru Emoto’s experiments on water molecules actually proved that our thoughts, attitudes, emotions, and intentions could physically change the molecular structure of water .

For example, the crystals formed with water introduced to words of “love and gratitude” were clear, big, and beautiful. Similarly, water from various sources was exposed to prayers. Pictures before and after prayers showed mesmerizing changes in the molecular structure of water. The after-prayer structure in each case was much more defined and beautiful. 

dr. masaru emoto photography  crystal experiments

Thought about hate also resonates in water molecules, and thus it forms ugly and aesthetically less appealing crystals.

Dr. Emoto has conducted different experiments on the subject. To understand the importance and value of his work, let’s take a closer look at those experiments below.

Dr. Masaru Emoto’s Water Crystals Experiment and Its Findings

Masaru Emoto used high-speed microscopic photography to observe the crystals formed in the frozen water after exposing them to specific thoughts. Dr. Masaru Emoto’s method was freezing various 0.5ml water samples. For each case, at the temperature between -5 and 0°, different kinds of crystals were formed. Based on the crystals, Dr. Emoto withdrew conclusions about various water molecular structures.

When he exposed water to positive thoughts and loving words, the crystals formed beautiful, colorful, and snowflake-like patterns . On the contrary, when polluted water and the water exposed to negative word/thought were crystalized; incomplete, dull, and asymmetrical patterns were observed.

In a 2006 study , a group of researchers, including the Japanese water scientist Dr. Masaru, tested the hypothesis: water, when treated “with certain intention” can affect the ice crystals formed. The study was carried out under double-blind conditions. They took a sample of approximately 2,000 people in Tokyo who were instructed to make positive intentions toward water samples inside an electromagnetically shielded room. Similar water samples were also kept in different locations as a control. Ice crystals were formed from both sets of water and then photographed.

Then these images were blinded and tested for their aesthetic appeals by 100 independent judges. Surprisingly, the results showed that water treated with positive intentions received much higher scores than the controlled water samples.

dr. masaru emoto photography - crystal experiments

Dr. Masaru’s experiments proved that the molecular structure of water can be altered. This is based on water’s ability to retain the memory of everything it comes across. Positive words/good thoughts can bring positive changes to water.

Similarly, because nature is soothing and peaceful, the crystals formed from natural spring water were found more symmetrical, well-balanced, and attractive in Emoto’s experiments.

Water experiments done by Dr. Emoto convey a clear message about the water we use. Drinking clean water with positive energy can have a beneficial impact on our well-being. Water with a negatively altered molecular structure is not suitable for the human body at all. Therefore, it is imperative to treat water with love and care before we use it for drinking purposes.

Ultimately, water will become a part of our bodies, our plants, and our environment. For this purpose, we have to use water in its optimal state in order to receive the most benefits possible. For this, we have to look at structured water, also dubbed vortex water. 

Just as water’s crystals alter with positive intentions, its movement can also change its inner structure. Science says that water molecules found in our rivers, streams, and other natural waterways are secured by vortex-like movements.

These movements create hexagonal micro-clustered molecular forms, similar to those experiments conducted by Dr Masuru. These inner molecular forms give water impeccable benefits such as self-cleaning, increased levels of dissolved oxygen, balanced pH levels, and much more. Perhaps that’s the reason Dr. Emoto found the structure of natural water more enchanting.

Understanding the consciousness of water through Dr Emoto’s water experiments, we can see just how vital water’s state is, but the water that we receive in our taps passes through unnatural and harsh treatment. This adversely impacts the water structure. Resultantly, tap water is depleted of qualities such as self-cleansing, optimal hydration, and balanced pH. 

Keeping the finding of Dr. Emoto in mind, we know that ordinary tap water with adverse molecular structure can be hazardous to our health. What we actually need to do is to revitalize our tap water and bring it back to its original form.

With The Vortex Water Revitalizer™ , bringing ordinary tap water to its natural molecular state is easy. The water goes through a vortexing motion, imitating the motion water naturally goes through in nature.  technology puts water through the natural vortex movement. After that, the harm caused to the water and its structure is eliminated.

As the structure is restored, water’s natural benefits double in all forms. Water becomes cleaner, more hydrating, and balanced, providing monumental advantages to our bodies, our homes, and our environment.  

According to Dr. Masaru Emoto the philosophy regarding water consciousness, The Vortex Water Revitalizer™ that takes water’s natural needs into consideration is considered an optimal treatment solution. Water is a miraculous resource that proves to be a living system. With Dr. Emoto’s water experiments and the technology of The Vortex Water Revitalizer™ , it is possible to reap the benefits of water consciousness in your home .

February 13, 2022 Love and Gratitude Matthew 10:42

At the church yard-sale this past summer I picked up this book, The True Power of Water, by Masaru Emoto. I saw it years ago at a book store, but did not buy it. This time I bought it and couldn’t put it down. The book is so interesting, and it pulls together so many of the concepts I cherish. You may have read the book, but let me summarize it for those who haven’t. Masaru Emoto was reading a book and came upon the question, “Are there any identical snow crystals?” That question resonated within him and prompted him to begin a study of water. His plan was to take photographs of ice crystals. He got an assistant and set up a laboratory. It took two months before he got the first photo. The successful method was to freeze water in a petri dish, and, using a microscope, take a photograph of it during the thawing window, which was determined to be two minutes.

Emoto and his assistant took lots more photos of water from many different sources, including tap water from many cities in Japan and other countries. He tested bottled waters from supermarkets, and natural water from springs. Most water he found was tainted and would not form crystals, and treated water had deformed crystals. He found that the purest water was spring water, water that is filtered by the Earth, a process that he said takes 30 – 50 years. Spring water formed the most beautiful crystals. I will share more of his conclusions in a minute, and make the photographs in his book available to you, but suffice it to say that Masaru Emoto became known worldwide as the only person conducting such a study by photographing water crystals.

In his book, Emoto wrote about what he learned by studying water crystals. He started with the Japanese word, hado, which literally means “life vibration.” His expanded definition of hado is “the inherent energy in all things,“ and “all the subtle energy that exists in the Universe.” How similar this is to my best understanding of God – “the intelligent energy within all things causing them to live and evolve into higher forms of life in relation to their environment.” However, Emoto did his research without any religious cause to support. He merely tried to scientifically demonstrate the properties of water. He wrote, “I am not a man of religion, nor do I want to praise religions unnecessarily. However, the prayers used for a long time by a religion have a strong hado energy. I feel that if we believe in our religion faithfully and recite the prayers undoubtedly, we will be blessed with a strong power.”

Emoto measured the purity of water samples, and also discovered that water is affected by the messages applied to it. For example, he labeled identical bottles of water. One was labeled “You fool.” The other was labeled “Thank you.” When thawing, the water inside the bottle with the “Thank You” message formed a beautiful crystal, looking somewhat like a snowflake. The other water did not form a crystal at all, but the photograph looked more like a festering mass of points of light. The same results occurred whether the messages were written on the bottles, or if people spoke the messages to the water. It seemed to Emoto that the water had a consciousness of its own, and formed crystals in response to positive messages, as if to say “Thank you.”

This resonates with a concept I learned from studying near-death experiences. We are co-creators with God, and our actions, words, and even our thoughts have an effect on everything around us. This highlights the importance of living consciously, aware that we are having a continuous impact on the world around us. Emoto theorized that the vibrational energy we project affects everything at the sub-atomic level, then at the atomic level, the molecular level, and the cellular level. If allowed to continue over time, negative vibrations will even affect organs within the body and result in illness. Conversely, positive vibrations will result in good health.

Emoto and his assistant continued over the years taking water samples and photographing containers of water labeled with various messages. The most significant result was with water that was labeled “Love and Gratitude.” It formed a more beautiful crystal than any other. He described it as “joyful.” This resulted in his most significant teaching. Everything is energy, and everything has a vibration. Love is the highest vibration. Our healthiest state is achieved when we love someone or something beyond ourselves, and when we feel gratitude after having been loved. He wrote that you need to have both of them together, love and gratitude. Love can’t happen without a receiver. Emoto likened this to the sun and the moon. The sun gives. The moon receives. Love is extended and is received with gratitude.

Just sending love to others is not enough; you have to be willing to receive it too. Dr. Elizabeth Kubler-Ross is well-known as a forerunner in the field of death and dying. Recently I learned that she was a patient in a nursing home for several years before her death. Why did such a loving person have such an end? The answer is perhaps she needed to learn to accept love. Perhaps her stay in the nursing home receiving the care of others completed her life’s education. She gave love, and she finally learned to receive it.

In his book, The Purpose of Life, David Sunfellow included the story of Mary Deioma. She experienced what she called “a moment of enlightenment” while she was driving. This happened during a time of distress, and after she asked God for help. She writes, “In that moment a beam of pure white came out of the sky and came down and touched me on my shoulder. I was so filled with love it’s impossible to describe how much love there was in that moment. . . . And then my soul went out of my heart. My soul went up the beam and as it went up the beam I felt so connected to all souls. As I reached the top of the beam, I rippled out in concentric circles and I became one with every soul on the planet. Then my focus shifted and I became one with all the trees on the planet. Physically, I could feel that I was in a tree. And I was looking at another tree in the forest, which was me, looking back at me. It was so incredible. And then, I was all the grass and I was looking at a blade of grass next to me that was me looking back at me. It was amazing.

“Then my focus shifted and I was a rock on a mountain. I was the Earth. And that really surprised me because I never imagined that inanimate objects are filled with God Consciousness. Then my focus shifted again and it was all of the entire universe – the complete, entire universe. So humongous!

“At the same time, I don’t know how, but I could see the smallest, tiniest particle. What the universe is made out of. It was this massive, uniform field of particles. At the tiniest level, the tiniest particle, smaller than anything we can record, it was pure white, sort of a radiant light. This particle was pure energy. But more than that, this particle that everything in the entire universe is made out of, is LOVE! A tangible love that is the stuff of God. It just blew me away! It was awesome.

“I realized that at the same time all of this was happening, I was driving along the road. The whole thing didn’t take more than a second and a half.” In her story Mary affirms what Emoto taught about everything being energy and everything sharing God Consciousness. That would include water.

With sentient beings the exchange of energy is often reciprocated. One NDEr was admiring the beauty of a flower, and perceived that the flower sent back two photons of light. Love and Gratitude.

If we accept these things as true, then it’s important to know how to apply them to ourselves. Emoto points out that we are 70% water. We need to drink the purest water available, but we also need to monitor the energy we give to and accept from others. As far as taking in water, Emoto wrote that we can put a Love and Gratitude label on a container of water, and the water will respond by becoming purer. He wrote that we can also talk to and pray over the water. This is such a simple thing to do, and it resonates with so much truth. So I did it at home. I put a Love and Gratitude label on a pitcher of water, and I drink from it. Emoto has suggested doing it five times a day.

The experiments of Emoto affirm the effectiveness of prayer. He cites the story of Chief priest Houki Kato of a Japanese Esoteric Buddhist temple, who prayed at the fouled Fujiwara Dam for an hour. Water samples were taken before and after. After the prayer an observer said, “Wow! Look, the color of the reservoir is changing rapidly!” It got clearer. Earlier it had no reflection on top, but did afterward. Test results showed no crystals formed from the water sample taken before the prayer, but “a crystal of heavenly beauty” from the sample taken afterward. It had a double structure of a small hexagon inside a beautiful outer hexagon.” (See Fig. 3.3) Furthermore, Emoto taught for us to pray in the past tense, and to visualize the prayer as having already been answered.

Not only do we need to drink good water, but we also need to be mindful of the information we receive. Negative information will have a negative influence on us, and vice versa. This might apply to watching the news, selection of movies, video games for children, and even the company we keep. In his experiments, Emoto noted that water kept close to cell phones and computer screens failed to form crystals, unless it was labeled “Love and Gratitude.” That positive message seemed to overpower the negative effects of electronic radiation.

You may remember Marlon Colley. He had a spiritually transformative experience in which angels communicated many messages to him. One of the messages was for him to move out of the densely populated area of Virginia Beach because there was too much negative electronic vibration here. He related this and other messages he received at the Mind, Body, Spirit Discussion Group at my home many years ago. He said it was difficult for him to attend the meetings because of all the electronic vibrations, especially from my old TV set. He took the message of the angels seriously, and moved to a more remote location in southern Virginia Beach.

Emoto also observed the effects of hado in experiments with rice. He used three jars of rice. One was labeled “You fool,” the second “Thank you,” and the third was not labelled at all. It was ignored. The results were remarkable. After a month the rice in the positively labeled jar smelled mellow as of fermented malt. The rice in the jar labelled “You fool” turned black. The ignored rice turned black even before that. This experiment showed that receiving negative attention is better than receiving no attention at all. This informs us about the behavior of children and grandchildren who misbehave, even though they know they will get only negative attention.

Emoto reminds us to say positive and inspirational words to our children, and to give positive messages to those who are sick. He wrote that it sends a negative vibration to children to tell them, “Do this!” but a positive vibration to say, “Let’s do this together.” “Do this!”, when written on a water sample, made the shape of a frightening circle in the ice, but “Let’s do this together” formed a crystal Emoto described as “cute.”

I note that Jesus spoke of water when he taught about loving children. He said, “And if, as my representatives, you give even a cup of cold water to a little child, you will surely be rewarded” (Matthew 10:42). Emoto also created a device that would measure the hado in items he examined, including foods. He determined that different foods have different vibrations, and the various vibrations resonate with the various cells and organs of our body. That’s why we should eat a varied diet.

Emoto’s scientific conclusions for a good diet compare favorably with what Edgar Cayce said, what dieticians tell us today, and also what souls advanced into the future told Dr. Linda Backman. It’s a diet of healthy protein, fruits and vegetables, unprocessed grains and legumes. Backman recorded that dairy and gluten are acceptable unless there is an intolerance, and that meat should be ingested in moderate amounts, with fish and seafood as the main sources for protein. High-fat and fried foods are to be kept to a minimum or avoided. So what we accept as true today remains true in the future.

Emoto rated foods not only on their content, but on how they are prepared. He found that home-cooked meals rated high for value. That is food prepared with love. On the other hand, food prepared at home with anger had low hado. An example of this is “Why do I have to make such a troublesome dish when I don’t have time?” So Emoto recommended for those preparing meals to energize them with love, and for family members to receive those meals gratefully. When NDEr Howard Storm was recovering from a perforated stomach in a hospital in Paris, he was unable to keep any food down. His nurse told him she had a remedy. She would prepare a milkshake with love, and he would be able to keep it down. She did, and he did.

Emoto also applied his discoveries to healing. He wrote, “To live a healthy life, keep your thoughts positive. I am not a medical doctor, but I believe that all doctors should be philosophers as well as healers. The doctor’s deep insight and compassion heals patients.” He notes that in the old times doctors were deeply involved with spirituality and religion as priests and shamans. He recommended self-healing by writing the antonym of your illness or malady onto a label and putting it on your water container. He taught that water can be programmed to restore health.

Emoto further recommended from his findings to listen to music for its good effect. He wrote, “Good music reaches every one of our sixty trillion cells.” He recommended against heavy metal music, which did not form crystals. He recommended a positive daily routine, saying “Thank you” at every activity, affixing a Love and Gratitude note in the shower, on the phone and on the computer screen. He recommended for an exchange of air to avoid stagnation, noting that still water often stagnates. Open a window if the weather allows. He allowed drinking of alcohol in moderation inasmuch as it facilitates the expression of true feelings. He would allow no negative talk in social gatherings. He recommended that we fill our lives with those activites that cause us to want to say “Thank you,” and then to let the gratitude rise up within us.

Emoto’s experiments also give us hope. Lately we have been thinking about Earth Changes. The Earth is 71% water. Our prayers for the renewal of the Earth are effective. As an illustration, Emoto rated tap water in various cities three years apart. In one Japanese city, the water was tested but failed to produce a crystal, but the people of that city were prayerful about restoring the environment. Three years later the water was tested again, and it produced a display of beautiful crystals. Such prayer is a way for us to live in harmony with Nature, which is the future toward which we are moving.

The book is so easily understood, and easily applied. I brought lots of blank computer labels with me today. You can make some for yourself. I made some and put one on my water pitcher, over my computer screen, on my cell phone, and another one over the door of my granddaughter’s bedroom. I also brought blank 3×5 cards. I suggest that you write Love and Gratitude on one and keep it in your pocket. The message may transform your health and your life. In summary, everything is vibration. Your thoughts will resonate on everything around you. In your work, try to think of Love and Gratitude. Send Love to the people, animals, and plants within your engagement. Be appreciative, saying “Thank you” to everyone and everything that adds to your life. Your vibration will fly off the roof, and so will everyone else’s.

Now let me ask you, “Do you resonate with any of this?” Did it feel true to you? I see heads nodding in affirmation and thumbs up. On Coast-to-Coast AM on the night of Thursday, Nov. 4, 2021 I heard author Dean Radin talk about his book, Real Magic, and the research the led up to writing it. His scientific findings confirmed what Emoto wrote. In double-blind experiments people had better moods after eating chocolates that were blessed than others eating the same chocolates without such a blessing; and persons who drank a blessed tea has better moods after drinking the blessed tea than others who drank the same tea without a blessing. A third experiment was done with a species of plant that is known to respond to human emotions. There were two identical plants. One was watered with blessed water; the other with water that was not blessed. The one receiving the blessed water flourished noticeably more than the other.

All of this reminds me of the gratitude I have for the Earth and the plants that flourish in my garden.

So, speak kindly to one another. Bless one another with thoughts and words, and lift others in mood, mind, and body. And bless yourself with a grateful spirit. Amen.

Water Cycle Experiment

Experiment to change water into 3 phases.

Posted by Admin / in Matter Experiments

In this water science experiment we will see the water cycle in action as it transitions through 3 different phases including liquid, gas, and solid. The following items are needed to conduct the water cycle experiment.

Materials Needed

  • 2 metal cans (label removed)
  • rock salt or table salt
  • crushed ice
  • Food coloring

EXPERIMENT STEPS

Step 1: Fill both cans with crushed ice.

change water experiment

Step 2: Add water to both cans. Fill the cans to about 1" below the top of the can.

change water experiment

Step 3: Add 3-4 drops of food coloring to one of the cans. In the example, red food coloring was used. Stir in the food coloring to make a consistent color.

Step 4: Add 3-4 drops of food coloring to one of the cans. In the example, red food coloring was used. Stir in the food coloring to make a consistent color.

Step 5: Wait a few minutes and observe what happens to the outside of both cans.

water cycle

Step 6: Stir in about 3 tablespoons of rock salt or table salt into each can.

Step 7: Wait 15 minutes and observe the outside of both cans.

Science Learned - The Water Cycle

The air around both cans is cooled by the cold water. As the air is cooled it condenses. Water molecules in the air around the cans collect on the cold cans. The water is clear, not red because the source of the water is not from the can, but from the air around the can. When salt is added to the cans, the temperature of the ice water is lowered. This further cools the water that has collected on each can causing it to turn to frost. The experiment proves that water molecules in gas form will turn to liquid water when rapidly cooled. The liquid water will then turn to a solid (frost) when cooled below 32 degrees F.

The water cycle is an important part of the earth's natural science. The water cycle provides rain and snowfall which replenishes the water supply to help support life.

Rainbow Walking Water Science Experiment for Kids

This walking water science experiment is so much fun and super easy to do! My kids absolutely loved it! It even comes with free printable recording sheets for kids as young as preschool! Check out the video to see how easy this walking water experiment really is. This rainbow activity is perfect for spring science!

Walking water science experiment that is so much fun! This rainbow science activity is super cool!

Walking Water Science Experiment

Ok, this might just be our favorite science experiment! The whole family (adults included) were completely mesmerized with process. We all couldn’t believe how quickly the water traveled up the paper towel and neat it was to watch the colors mix together.

We have wanted to try it out for a long time now and I am kicking myself for waiting so long. I don’t know why, but I thought it might be difficult to do or take a long time. I was way wrong. It was very easy and we started seeing results right away!

This rainbow science experiment is a so cool!

Related: Simple Spring Science and STEAM Activities

The walking water science experiment is great at any time of the year, but it is especially perfect for spring. I love doing rainbow activities in the spring, so this was a great addition to our rainbow theme activities.

If you are looking for simple science to do with the kids and something that will really WOW them, this is definitely one to try.

You only need a few simple supplies that you probably already have around the house.

A super cool science experiment for preschool and elementary.

Setting Up the Rainbow Science Experiment

Supplies Needed:

  • Printable walking water recording sheets (button to download at the bottom of the post)
  • Small plastic cups or glasses
  • Paper towels (*read my tips below for picking the right ones)
  • Food coloring in primary colors

* The pick-a-size paper towels are best because then you just use half sheets for each cup. If you only have full sheets, then cut them in half. I’ve also heard that more absorbent paper towels work better too. I buy the cheap store brand ones, and our water moved pretty quickly from cup to cup, so I am not sure how important that is. It may have went quicker with something more absorbent though.

1. Print out the recording sheets and make copies, if needed.

2. Place 7 cups in a row and pour water in the 1st, 3rd, 5th, and 7th cup. My cups were about 3/4 full. I have since heard that fuller is better.

3. Add 5 drops of red food coloring to the 1st cup and the 7th cup.

4. Add 5 drops of yellow food coloring to the 3rd cup.

5. Add 5 drops of blue food coloring to the 5th cup.

This walking water experiment teaches kids about color mixing and capillary action.

Doing the Walking Water Experiment

You want to try to use the same amount of food coloring in each cup. When I did this with my kids they did drop an extra one or two in since they can’t control it well, but I just added a drop or two more to the others to even it out.

6. Take a half sheet of paper towel and fold it in half lengthwise and in half again lengthwise.

7. Trim off some of the length so that there isn’t too much excess paper towel that will stick up in the air between each cup. This will make the water walk more quickly.

8. Place one half of a rolled paper towel in the 1st cup and place the other half in the cup next to it. Then another paper towel from 2nd cup and into the 3rd cup. This continues until you have placed the last paper towel that drapes over from the 6th cup to the 7th cup.

9. Stare at the cups and watch what starts happening. You should quickly be able to see the colored water begin to crawl up the paper towel.

10. Don’t forget to do the first part of the recording sheet. Students will predict what they think will happen.

Color mixing science activity for kids.

This walking water experiment is AWESOME!

Keep checking back every couple of minutes. Soon you will be able to see that the water has crawled all the way up the paper towel and is beginning to walk back down into the empty cup next to it.

Since the cup on either side of an empty cup has colored water in it, the two colors begin to mix in the empty cup. So cool!

Keep coming back throughout the two hours or soon and observe what is happening.

Walking water science recording sheets.

Question to Ask

What do you think will happen to the water?

What is happening now?

Why do you think the colors are changing?

Why might the water be able to move up against gravity like that?

How this Science Experiment Works

The water moves up the paper towels through a process called capillary action. The paper towel is made from fibers and the water is able to travel through the gaps in the fibers. The gaps in the paper towel act like capillary tubes and pull the water upward. This is what helps water climb from a plant’s roots to the leaves at the top of the plant or tree.

The water is able to move upward against gravity because of the attractive forces between the water and the fibers in the paper towel.

I even removed one of the red cups and made a color wheel so I could introduce the kids to that as well.

I hope your kids have a great time with this super cool walking water science experiment!

Color Changing Water Science Experiment

Who knew a head of red cabbage could be so much fun? We actually did this color-changing water experiment the same day we did the pH indicator testing. One cabbage, two experiments. We love science experiments here and I hope you do too.

Color Changing Water

This post contains affiliate links, see my disclosure policy for more information.

This is a very easy science experiment and super budget-friendly science. Everything you need is for this, is in your kitchen. I like experiments to be easy and accessible for everyone.

Red Cabbage Science Experiment

With this experiment, I had no idea what to expect along with my kids. I think those are the best experiments., the ones we get to experience the magic together. It was the same when we did the cabbage pH indicator.

What You Need:

  • head or red cabbage
  • boiling water
  • baking soda

How to Make Water Change Color

The first thing to do is boil water, and pour that boiling water over ahead (or half ahead) of red cabbage cut up. The more cabbage, the more water you use, the more water you’ll have to do this experiment with.

Let it sit for about 30 minutes.

Now strain the water off your cabbage and into either clear small jars or into glasses. Your red cabbage water is going to look quite purple.

  • Pour a little white vinegar into your cabbage water.

  • Add a little baking soda .

Color Changing Water (Red Cabbage)

This color changing water science experiment doesn’t stop at one or two colors but you can add more baking soda to see more change.

12 Simple Water Experiments for Preschoolers & Kindergarteners

By: Author Tanja McIlroy

Posted on Last updated: 5 June 2024

Categories Activities for Preschoolers & Kindergarteners

Here are some fun water experiments for preschoolers and kindergarteners, to help them discover the properties of water, how it changes, and its effects on other substances.

Water surrounds us. We see it everywhere in nature, and it hides within the pipes of our homes until we open a tap and let it flow. Water is essential to support a healthy environment and healthy bodies. 

Because of water’s far-reaching importance in our lives, we want to make sure that young children have many chances to learn about its significance.

Use these science experiments with water to expand kids’ vocabulary. They are the perfect opportunity to introduce children to new words and science concepts such as:

  • Solid 
  • Liquid 
  • Buoyancy 

…and lots more.

Wade right in, testing the waters while watching the fun!

1. Water Exploration Station

Outdoors or inside, set up a large tub or well-supervised kiddie pool partly filled with water. Add an assortment of plastic containers for pouring, including funnels and colanders. 

Children learn a great deal about the properties of water just by experimenting on their own. They also learn early maths concepts such as capacity and volume.

Keep towels handy to dry off your young scientists!

Fill a large, clear container with equal parts of water and oil (cooking or baby). 

Challenge kids for guesses (“hypotheses”) about what could happen when the materials are combined. 

After observing how the water and oil do not mix, ask for ideas of why that is the case, which includes the heaviness (“density”) of water. 

Water and oil separating in a glass

Introduce food colouring and discuss whether that is most like the oil or the water. Drop the colouring into the liquid mixture with a pipette or eyedropper. 

Discuss the results and what those tell us. Introduce the term “suspension” for liquids that do not mix in this oil-water experiment.

3. Solid to Liquid

Give each child a clear, plastic container to which they add fine table salt with a spoon for this simple water experiment for kids. 

With pipettes, ask them to start adding small amounts of water. They can observe the salt turning a bit darker as it soaks up (“absorbs”) the water. 

As they stir, kids also see that the salt looks like it is melting  (“dissolving”) and forming a “solution.” 

Try the same experiment with coarser salt crystals. How does the process of dissolving differ? 

Try the salt-water experiment with water of different temperatures as well. Does anything change in the process?

4. Exploring with Ice Cubes

Remind children that the cubes are not to be eaten or placed in their mouths since these are a choking hazard. 

Offer ice cubes (water in a solid form) and an assortment of plastic containers for kids to stack/build, stir and pour. 

Discuss: 

  • What starts to happen with the cubes? Why? 
  • Outdoors, is there a difference in the results when working in the shade or in the sun?
  • Why is the ice melting? 

Then have them add ice cubes to separate containers of cold and warmer water. 

  • What is the difference in the results?

5. Sink or Float?

Set up a basin or tub partly filled with water. Offer a variety of small objects like corks, paperclips, ice cubes, fabric, coins, pencils, marbles, cotton balls, bar soap and crayons. 

Ask children to predict for each object whether it will sink or float in the water and then give it a try. 

Ask why they think the object is either floating or sinking in the water, which leads to a discussion on “buoyancy” and “density” or heaviness. 

6. Changing the Shape of Water

Fill plastic measuring cups with equal amounts of water, which may be tinted with food colouring. 

Water in containers with food colouring

Children pour those amounts of water into different shapes and sizes of containers. They observe how the same amount of water looks very different in various containers. 

Ask for their ideas of why they think it works this way.

7. Oops, a Water Spill!

Talk about what kids and parents grab when water or other liquid spills. 

Why do we use those materials? Discuss the word “absorption.” 

Set out low tubs of water and various objects to test: sponges, paper towels, socks, foam letters and washcloths. 

Have them place one object at a time in the water and then squeeze the soaked-up liquid into silicone muffin cups that have been labelled for each.

Little girl squeezing' water out of wash cloth, leaning over bucket of soapy water

Which materials absorbed the most or least water? Ask them why they think it worked that way. 

Introduce the science concept of “porosity” related to some materials being more “porous.”

8. Pushing Water Out of the Way

Set up a clear container partly filled with water. Mark the current water level on the side. 

Before asking kids to place objects into the water, ask them to predict what could happen. 

Then, have children add one stone or object at a time to observe what happens to the water level. 

After observing the rise in the water level, see if they can guess that the water is being pushed out of the way, or being “displaced,” while it makes space for each object being added. 

9. Rainbow Water

On a sunny day, set out a clear container of water and a sheet of white paper. Place the water so that sunlight shines through it onto the paper to observe the rainbow.

Lead children into the understanding that rainbows occur when sunlight shines through water, just like they have seen on rainy days when the sun peeks out. 

The light is “refracted” or separated into different colours, appearing as a rainbow. Teach them the colours with these rainbow songs .

10. Learn About Erosion

Outdoors or on a sand table inside, form a mountain of dirt or sand. Pour water slowly onto the mountain and observe what happens. 

Child making a hill with sand

Do you see differences if the water is sprinkled or poured more quickly? Do you observe differences when using sand vs. dirt? 

Explain to children how this is like real-life “erosion” from rains and floods.

11. Easy Evaporation

Fill a clear plastic cup with water and draw with a permanent marker at the water level line. Place it in a sunny window. 

Mark the new water level each hour to track the “evaporation.” 

Kids could guess that the heating of the water from the sun contributes to evaporation, which is the liquid water turning into a gas, referred to as “water vapour.”

12. Water Cycle in a Bag

Take the idea of evaporation a step further by adding the water to a sealed plastic bag instead of the open cup in the previous experiment. 

Before adding the water, clouds may be drawn with a permanent marker near the top and grass and flowers near the bottom. 

Tape the bag to a sunny window and watch the evaporating water “condense” and stick to the sides and upper area of the bag, much like clouds. 

The water eventually comes back down just like rain!

Last but not least, be sure to check out your local library for picture books about water. Hey, Water! by Antoinette Portis (2019) is a great place to start.

Walking Water Rainbow Science Experiment

Let’s make a walking water rainbow! There’s no better way for little scientists to learn about capillary action and color mixing than by making water walk (yes – walk!) in this colorful rainbow science experiment. This science experiment is a favorite of ours because it’s so easy to set up and the results are almost immediate.

Check out the simple step-by-step below and then gra b 30 more jaw-dropping (but easy prep!) science experiments kids will love from our shop!

Walking Water Rainbow Science Experiment

Getting Ready

To prep, I gathered our supplies:

  • 6 wide-mouth glasses or jars
  • Paper towels (use the kind where you can select a size)
  • Food dye or liquid water colors (red, yellow, and blue)

I grabbed the six small glasses first .  We’ve had success using wide-mouth drinking cups and canning jars, too.  Even though they all worked, just remember that bigger glasses will need more food coloring.

Walking Water Rainbow Science Experiment

I ripped off six sheets of paper towel and folded each sheet in thirds, lengthwise.

We were using pretty small glasses, so I cut a few inches off the folded paper towel so it would fit in the glasses.

It’s a good idea to test your paper towel strip to make sure they fit properly in your glasses.  They should be able to go from the bottom of one jar to the next without sticking up in the air too much. The paper towel on the left shows the just-right height.  It’s important to set up this rainbow science experiment for success!

Walking Water Rainbow Science Experiment

Making a Rainbow

This colorful rainbow science experiment is so simple and quick, it’s perfect for even the youngest little scientists.  My 3 year old, Q, couldn’t wait to get started.

First, I had him line up the glasses and fill the first one with a good squirt of red watercolor , the third with yellow, and the fifth glass with blue.  We left the other glasses empty.

Walking Water Rainbow Science Experiment

Next, I helped Q add water to the glasses with color until the colored water almost reached the top.

We moved the glasses into a circle and added the paper towels .  Starting with the red, we added one end of the paper towel and then put the other end in the empty glass next to it.

We continued around until the last paper towel was placed into the red glass.

Walking Water Rainbow Science Experiment

We saw the color wick up the paper towel right away.  This rainbow science experiment doesn’t take long to get going!

Cool science for kids! Make a magic water rainbow. My kids will love this!

After another several minutes, the colored water had almost travelled the whole length of each paper towel.

Awesome science experiment for kids! Make a walking water rainbow.

Five minutes later, the water had traveled all the way up and then down the paper towel and was dripping into the empty glass.

The yellow and red water dripped into the empty cup to make orange!  It made for a good lesson on color mixing.

Cool science for kids! Make a walking water rainbow.

After another five minutes, we could see the water level had dropped in the red, yellow, and blue glasses and rose in the once empty glasses as the water continued to travel from the more full glasses to the less full glasses.

Super cool science for kids! Make a walking water rainbow.

We grabbed a snack and watched our beautiful rainbow science experiment during the next 20 minutes. The water continued to walk from the primary colored glasses to fill the secondary-colored glasses until all the jars were filled equally.

What an awesome science project for kids! Make a walking water rainbow with just a few simple supplies.

Not Working?

If you aren’t seeing much movement within a few minutes, it may be that you need to add more water to your colored water glasses.  It really needs to be almost at the top for the water to walk quickly.  So try topping off those glasses and seeing if that gets things moving.

If you see the water moving up the paper towel but it seems like it’s taking forever , it may be the type of paper towel you are using.  You want a paper towel that will really hold a lot of water.  We have used Bounty Select-a-Size and Target’s Up and Up Brand Select-a-Size with success.

It really is worth the extra effort of trying different cups and paper towels to get this activity to work.  And once you have had success, don’t throw out those beautifully-colored paper towels or the colored water!  We gently squeezed out our paper towels and let them dry in a heap on a baking sheet.  We ended up with gorgeous tie-dyed looking paper towels to use for crafts and we used the leftover water as watercolors for painting with later.

I love the colors in this cool science activity! Make a walking water rainbow.

The Science Behind It

This rainbow science experiment is as magic as the science behind it.  The colored water travels up the paper towel by a process called capillary action . Capillary action is the ability of a liquid to flow upward, against gravity, in narrow spaces.  This is the same thing that helps water climb from a plant’s roots to the leaves in the tree tops.

Paper towels, and all paper products, are made from fibers found in plants called cellulose .  In this demonstration, the water flowed upwards through the tiny gaps between the cellulose fibers.  The gaps in the towel acted like capillary tubes, pulling the water upwards.

The water is able to defy gravity as it travels upward due to the attractive forces between the water and the cellulose fibers.

Cool science experiment for kids! Make a walking water rainbow.

The water molecules tend to cling to the cellulose fibers in the paper towel.  This is called adhesion .

The water molecules are also attracted to each other and stick close together, a process called cohesion .  So, as the water slowly moves up the tiny gaps in the paper towel fibers, the cohesive forces help to draw more water upwards.

At some point, the adhesive forces between the water and cellulose and the cohesive forces between the water molecules will be overcome by the gravitational forces on the weight of the water in the paper towel.  

When that happens, the water will not travel up the paper towel anymore. That is why it helps to shorten the length that colored water has to travel by making sure your paper towel isn’t too tall and making sure you fill your colored liquid to the top of the glass.

Rainbow Science Activity Extensions

Turn this demonstration into a true experiment by varying the water level (volume) you start with and seeing how long it takes the water to reach the empty glass.

Or start with the same volume of colored water and change the brand, type (single vs double ply, quilted vs not) or length of paper towel to see how long it takes for the water to “walk” to the empty glass.

You could even use the same volume of water, same length and brand of paper towel but vary the height of the filled glass , by raising them up on books, to see how that affects the speed of the water as it “walks” to the empty glass.

Have you had enough fun with the paper towels?  Try using other paper products to see how the type of paper effects the results.  Try toilet paper, printer paper, newspaper or a page from a glossy magazine.  What do you predict will happen?

Emoto’s Water Experiment: The Power of Thoughts

Through the 1990’s, Dr. Masaru Emoto performed a series of experiments observing the physical effect of words, prayers, music and environment on the crystalline structure of water. Emoto hired photographers to take pictures of water after being exposed to the different variables and subsequently frozen so that they would form crystalline structures. The results were nothing short of remarkable..

Cape Cod scientists want to dump 60,000+ gallons of sodium hydroxide into ocean in climate change experiment

by Lance Reynolds, Boston Herald

Cape Cod

Environmentalists and fishermen are pushing back against a plan from a group of scientists who want to dump more than 60,000 gallons of sodium hydroxide, more commonly known as lye, into the ocean off Cape Cod to gain an understanding of how to slow climate change.

Scientists from Woods Hole Oceanographic Institute in Falmouth are seeking a federal permit for their project, which would start sometime this summer with a field trial program that would disperse roughly 6,600 gallons 10 miles south of Martha's Vineyard.

Woods Hole says there are two central goals to its so-called LOC-NESS project, short for "Locking away Ocean Carbon in the Northeast Shelf and Slope."

The first is to "understand potential environmental impacts of using ocean alkalinity enhancement to remove carbon dioxide from the atmosphere." The other is to "verify and report the amount of carbon dioxide this method might realistically remove if deployed at scale."

"While emission reductions are key to minimizing human impact on Earth's climate, it has become clear in recent years that drastic emission reductions must be supplemented by efforts to actively remove existing carbon dioxide from the atmosphere," Woods Hole scientists wrote in their application to the Environmental Protection Agency.

Environmentalists and fishermen are not taking kindly to the proposed experiment which would continue next summer at a more drastic scale of roughly 60,000 gallons in the waters northeast of Provincetown, in the Gulf of Maine.

Friends of the Earth is one of the dozens of groups that wrote to the EPA against the project during a public comment period that closed Friday.

They highlighted how ocean alkalinity enhancement—a process that adds alkaline substances to seawater to change the ph and enhance the ocean's natural carbon sink—is "under moratoria under the United Nations Convention on Biological Diversity due to the risks and uncertainties that these technologies entail to biodiversity and ecosystems."

"Sodium hydroxide is an incredibly dangerous substance," Friends of the Earth senior campaigner Benjamin Day told the Herald. "It causes chemical burns if it touches your skin or marine animals. We think dumping tens of thousands gallons of that into the ocean is a bad idea."

Proposals typically seen for alkalinity enhancement use minerals, like limestone, that create a "different set of problems," Day said. Sodium hydroxide presents more immediate issues, he added.

Woods Hole scientists say the project will "operate within a pH range considered safe for aquatic life (and) maintain strict environmental monitoring protocols."

Scientists will then constantly monitor the alkalinity patch, "using a suite of instruments, sensors, and sampling equipment."

"The results of these monitoring efforts will provide some of the first in-water measurements of the safety of OAE," scientists have said, "including its impacts on water chemistry, the marine food web, and larger organisms such as copepods."

Alison Brizius, director of the Massachusetts Office of Coastal Zone Management, says she believes the project is much needed to understand the effectiveness of marine carbon dioxide removal.

"This study has the potential to inform future work as mCDR research continues and possible commercial-scale applications are developed," she wrote in a letter to the EPA on Friday.

Fishermen across the region are afraid of how the experiment could affect their operations.

Robert Scammon, a commercial groundfish captain who has fished the Gulf of Maine and George's Bank for 37 years, said the targeted area for testing has produced 30 to 40% of his catch in that time.

Jerry Leeman, CEO and founder of the New England Fishermen's Stewardship Association, added he believes the "project is being done in haste, and without proper oversight."

"Major impacts to the commercial and recreational fisheries are likely, which would cause severe economic turmoil (and loss of commercial and recreation opportunities) to the neighboring states' fisheries, in addition to the immediate test site," he wrote in a letter.

Can you see thermal energy? Yes, with just a few common kitchen items!

Although we can explain that molecules move faster when hot and slower when cold, in this science experiment kids will be able to see thermal energy in action and explore the concept hands-on.

We’ve included a materials list, printable instructions, and a simple explanation of how the experiment works. Enjoy our demonstration video to get started!

Water Temperature Science Experiment

JUMP TO SECTION: Instructions | Video Tutorial | How it Works

Supplies Needed

  • 3 Glass Jars
  • Room Temperature Water
  • Food Coloring

Water Temperature Science Lab Kit – Only $5

change water experiment

Use our easy Water Temperature Science Lab Kit to grab your students’ attention without the stress of planning!

It’s everything you need to  make science easy for teachers and fun for students  — using inexpensive materials you probably already have in your storage closet!

Water Temperature Science Experiment Instructions

change water experiment

Step 1 – Begin by preparing three identical jars of water. Fill one jar with cold water, one jar with room temperature water, and one jar with hot water.

Helpful Tip: For cold water, fill the jar and put it in the fridge for an hour or two. For the room temperature water, fill the jar and leave it on the counter for an hour or two. For the hot water, boil the water on the stove or put it in the microwave for a minute or two.

Before moving to the next step, take a moment to observe the jars. The temperature of water should be the only difference. Do you think the water temperature will impact what happens when the food coloring is added to each jar? Write down your hypothesis (prediction) and then continue the experiment to see if you were correct.

change water experiment

Step 2 – Place 2-3 drops of food coloring in each jar and observe what happens.

You’ll notice right away that the food coloring behaves differently in each jar. Was your hypothesis correct? Do you know why the food coloring slowly mixed with the cold water and quickly mixed with the hot water? Read the how does this experiment work section before to find out the answer. 

change water experiment

Video Tutorial

How Does The Experiment Work?

When observing the food coloring in the water, you will immediately notice that it behaves differently based on the temperature of the water.

Even though the glasses of water look the same, the difference in the water temperature causes the molecules that make up the water to behave differently. Molecules that make up matter move faster when they are warmer because they have more thermal energy and slower when they are colder because they have less thermal energy. In this experiment, the molecules in the hot water are moving around much faster than the molecules in the cold water.

Thermal Energy is the total energy of the particles in an object.

When placed into water, food coloring will begin to mix with the water. The food coloring will mix the fastest in the hot water because the molecules are moving fast due to their increased thermal energy. These fast-moving molecules are pushing the molecules of food coloring around as they move, causing the food coloring to spread faster.

The food coloring in the room temperature water will take longer to mix with the water because the molecules are moving more slowly due to their decreased thermal energy.

Lastly, the food coloring in the cold water will take a long time to mix with the water because the molecules are moving even slower due to a further decrease in thermal energy.

More Science Fun

Eventually, the food coloring will mix throughout all of the jars. Expand on the experiment, by estimating how long it will take to mix with the water in each jar. Then set a timer and find out how close your estimate was.

In addition, you can also try these other fun experiments using water and food coloring:

  • Walking Water Science Experiment – Can water walk upwards against gravity? No, not really, but what makes water seem like it defies gravity is what we’re going to explore in this easy science experiment.
  • Color Changing Walking Water Science Experiment   – Much like the regular walking water science experiment, but with an added “colorful” twist.
  • Coloring Changing Water Science Experiment – Science or magic? Try this experiment at home with your kids and watch their eyes light up as you pour the liquid into the bowl and “create” a new color.

Scientists Say Sha’Carri Richardson Could (Theoretically) Walk On Water

Image may contain Athlete Person Sport and Adult

Vogue digital cover star Sha’Carri Richardson is the fastest woman in the world, and now scientists (sort of) say she’d be able to run on water. At least, that's the news according to a delightfully nerdy physics thought experiment.

In an article published in Physics World to celebrate the forthcoming Paris Olympics , fluid dynamics expert Nicole Sharp wondered if it would be physically possible for a human athlete to run on water. The answer is… yes… but also, not really. Per Physics World, there are a number of animals that can walk on water, perhaps most notably the basilisk lizard, also known as the “Jesus Christ lizard,” named after the other guy who could famously walk on water (allegedly).

Scientists have studied the basilisk lizard and other water-traversing creatures, like the Western grebe, for decades, as Sharp outlines in her article. Basically, those scientists came to the conclusion that in order for these animals to be able to run on water, they have to counteract their own weight by slapping the shit out of the water with their feet (and yes, slap is actually the word they use). One scientist found that grebes take up to 20 steps per second, whereas the average Olympic sprinter takes about five steps per second.

In a study published in the 1990s, Harvard researchers calculated that theoretically, a 176-pound human “with an average foot size and a world-class sprinter’s stride rate” would need to slap the water at a speed of 30 meters per second in order to support their own weight, which is physically impossible—at least on Earth. So in 2012, a group of researchers at the University of Milan set out to determine whether reduced gravity conditions could hypothetically enable humans to run on water. The study won the 2013 Ig Nobel , a satiric prize that rewards nerds who are so committed to the bit that they seek to answer questions with next to no practical application. (And the footage of said experiment, as Physics World puts it, is “spectacular.”)

Anyway, all of this is to say that decades of research have culminated in an answer to a question that no one has previously dared to ask: Could Sha’Carri Richardson run on Titan, Saturn’s largest moon? Because of Titan’s lighter gravity and Richardson’s speed, the answer is yes. Sharp theorized that the runner would have to “slap the surface” of Titan’s ethane lakes at 8.7 meters per second, and she’s already far outpaced that with her world-championship time of 9.3 meters per second.

And listen, if we have the funding to bring the military-industrial complex to outer space, someone out there has to have the cash to make Richardson the first woman to walk—er, slap—on the surface of a body of liquid. If there’s a chaotic good version of Elon Musk out there, please hear our plea.
