Error message, sorting salt and pepper, how many ways.
In the Sorting Salt and Pepper video we saw that we could mix salt and pepper into a pile and then separate them easily by using the static charge on a balloon. That is one way to separate salt and pepper, but there are many others. How many can you think of? Don't read any more until you have spent some time thinking of as many different ways as you can.
We start with a pile of mixed salt and pepper. How are we going to sort them out? Well, start by thinking about how salt and pepper are different. Think about how you could use those differences to separate the two materials. How many different ways can you think of? Take some time, and really think about it before you go on. Make a list, and then compare it with the answers below. If you thought of one that I missed, let me know.
The first difference that many people noticed was that salt will dissolve in water, but pepper will not. Quite a few of you suggested putting the salt and pepper in water. The pepper floats on the surface, while the salt sinks to the bottom and then dissolves. You can then evaporate the water to recover the salt. Carolyn not only tried that, she sent me some wonderful photos of her experiment. Jeffrey suggested adding a drop of dish detergent to get the pepper to rush to the side of the bowl, making it easier to collect.
Another difference is their density. The grains of salt are heavier than the flakes of pepper. We used that with the static charge on the balloon, attracting the lighter pepper flakes. Other ideas on using density included:
1. Either coating the salt or using a liquid that the salt would not dissolve in, such as oil. The salt sinks and the pepper floats.
2. Blowing or using the wind to blow the lighter pepper away from the heavier salt.
3. Taping or shaking the mixture, so the denser salt settles to the bottom, leaving the pepper on top.
4. Placing the mixture on an incline and vibrating it. The denser salt will move downwards faster.
5. Throwing the mixture across a long sheet of newspaper. The air resistance will stop the pepper quickly, while the heavier salt will fall on the other side of the paper.
6. Dropping or throwing the mixture onto a piece of paper, the denser salt will bounce more, leaving a pile of pepper with salt around it.
7. Use other sources of static charges, such as cellophane tape or a plastic comb to attract the lighter pepper.
The salt and pepper also have different sizes and shapes, which lead to more idea.
1. Using a screen or sieve to let the smaller pepper flakes fall through, while the larger salt grains are trapped.
2. Rod came up with a great idea of placing the mixture between two panes of glass. With a little pressure, the salt grains are held in place, but flat flakes of pepper fall out.
You can also use adhesion. As we saw in the Spoon on Your Nose video , adhesion can cause materials to stick to some things, but not to others. Pepper sticks to most cling wraps, but the salt usually does not.
All the entries boiled down into these eleven basic ideas, but I am certain that there are more. If you think of more, let me know. I am delighted that so many of you put on your thinking caps and sent in your ideas. My goal is to get people thinking about science, and actually playing with it themselves. This challenge seems to have done that, so look forward to more of them in the near future.
Have a wonder-filled week.

In this fun and easy science experiment for kids we are going to explore static electricity and use it to make pepper appear to jump.
EXPLORE AWESOME SCIENCE EXPERIMENT VIDEOS!
As the plastic comb moves through hair, it builds up a negative charge. Things that have a negative charge attract things that have a positive charge. While both the salt and pepper have a positive charge, the pepper is lighter and thus moves more easily and appears to “jump” and separate from the salt.
Try different items like sugar, baking soda, cinnamon, and various spices. Are you able to negatively charge other items like a balloon, plastic utensil, etc. Test to see if the experiment will still work if the items are put in water.

Step-4: Add Pepper into the salt. Measure the same quantity of ground pepper and put it into the plate. Now mix both the ingredients. No wonder, kids are very much interested in mixing any kind of things. My kids are also excited to mix salt and pepper. Step-5: Rub your balloon with a woollen cloth.
Colored notebook. Procedure. Place the colored notebook on a flat surface. Pour out a mixture of salt and pepper with an arbitrary amount of each condiment onto the center of the notebook. Blow up the balloon. Aggressively rub the balloon for 1 minute on your head. Place the balloon over the mixture of salt and pepper and observe what happens.
For this activity, you will need: 1 teaspoon of salt. 1 teaspoon of pepper. 1 balloon. Mix the salt and pepper in a pile. Then, quickly rub the balloon on your head and hold it close to the pile. Watch as the pepper jumps away from the salt! Rub the balloon for different lengths of time to hold different amounts of static to pick up more pepper.
Salt. Pepper. Beakers, glass jars, or plates. A miscellaneous assortment of items for separating the mixture (spoons, paper towels, tweezers, straws, balloons, magnifying glasses, water, etc.) Always remember to use the appropriate safety equipment when conducting your experiment.

Separate Sale and Pepper Science Experiment Instructions. Step 1 - Begin by adding 2 tablespoons of salt onto an empty plate. Step 2 - Next, add 1 teaspoon of pepper to the salt and gently shake the plate to combine the salt and pepper. Step 3 - Take a clean plastic comb and run it through your hair a few times.
Instructions. Mix a teaspoon of salt and a teaspoon of pepper in a small bowl. Blow up the balloon and rub it for about 30 seconds on a wool garment or your hair. Hold the balloon over the bowl of salt and pepper. Only the pepper will jump up to the balloon. If you listen carefully, you'll hear a cracking sound like static electricity!
Separate Salt and Pepper with Static Electricity • The Science Kiddo. Using a magic spoon to separate salt and pepper with static electricity is a quick and easy science experiment. Perfect for preschool and kindergarten!
1. Shake some salt and pepper in a small dish (most likely your child will want to do this). 2. Stir the salt and pepper together. 3. Ask your child if he/she can think of a way to separate pepper from salt WITHOUT using his/her hands (most likely met with puzzled looks). 4. Blow up a small balloon. 5.
In this experiment, we will accomplish the seemingly impossible feat of separating salt from pepper after they have been mixed together. Equipment.

Shubhang demonstrates the power of electricity by using a balloon to separate a mixture of salt and pepper.
Everyone knows this experiment: You mix salt and pepper and use a charged balloon to separate the pepper from the salt. I never really understood how this works. In school (long time ago) we learned that unlike charges attract each other while like charges distract each other. In the experiment the negatively charged balloon attracts the pepper.
Salt; Pepper; Procedure. Blow up two balloons. Rub each balloon on your hair, a carpet, or with a piece of wool for about 30 to 45 seconds. Sprinkle some salt onto a plate or tabletop. Bring the charged balloon near the salt. What happened? Why? Now, sprinkle some pepper onto the table so that you have a mixture of salt and pepper.

Add some salt and pepper to the plate and stir them together. Use equals parts salt and pepper. Now take the comb and run it through your hair. The person doing the demonstration must be the one that keeps holding onto the comb. Hold the statically charged comb over the bowl and watch the pepper jump. If you get too close, the salt may jump ...
Have her hold the spoon about an inch above the pile of salt and pepper. Both salt and pepper will be attracted to the spoon, but pepper is lighter, so if she holds the spoon in the right place, the pepper should jump up and cling to the spoon!
