cola experiment zucker

Versuch Nr.033 Cola - Experimente (Rostschutzmittel) Versuch Nr.034 Cola - Experimente (Inhaltsstoffe)

Ziel: Cola, jenes braune, bei Kindern und Erwachsenen in gleicher Weise beliebtes Getränk hält bei genauer Betrachtung einige Überraschungen auf Lager.

Durch den sehr hohen Zuckergehalt hat Cola eine von Wasser unterschiedliche Dichte und verursacht deshalb ein verblüffendes Phänomen. Ebenso hat Cola einen hohen Säuregehalt.

Geräte: Reagenzgläser, Stativ, pH-Papier, Spritze, Bechergläser

Chemikalien: Cola, Salz, Wasser

Sicherheitshinweise: keine Sicherheitsmaßnahmen notwendig

Einverständniserklärung: Hiermit erklären Sie sich bereit den folgenden Versuch unter eigener Verantwortung und nur mit ausreichendem chemischen Wissen und geeigneten Schutzvorrichtungen durchzuführen! Der Autor kann für jegliche Personen- und Sachschäden durch mögliche Fehlversuche nicht haftbar gemacht werden. (siehe Sicherheitscheck bzw. Disclaimer )

pH-Wertmessung: Misst man den pH-Wert von Cola, so fällt auf, dass er relativ niedrig und somit im sauren Bereich liegt. Der pH-Wert liegt ungefähr bei 3 und ist damit niedriger als der von Mineralwasser (pH=6-7) (nur sehr wenig Kohlensäure). Unten auf dem folgenden Bild ist ein unbehandeltes pH-Papier-Stück.

Interessant ist die pH-Wertmessung des Filtrates aus Versuch Nr.034 "Cola - Experimente (Inhaltsstoffe)"

Erklärung / Hintergrund: Dichteversuch: Was leichter ist, schwimmt immer oben...so kennt man es aus dem normalen Leben. Und so kann auch dieses Phänomen erklärt werden. Die Dichte der Cola ist höher als die Dichte von Wasser und so vermischen sich die beiden Flüssigkeiten nicht. Das Salzwasser wiederum hat eine noch höhere Konzentration und damit eine größere Dichte als die beiden überstehenden Flüssigkeiten.

pH-Wertmessung: Cola-Getränke enthalten neben der schwachen Citronen- und Kohlensäure auch die anorganische Phosphorsäure. Deshalb ist der pH-Wert relativ niedrig und damit Cola sauer. Beim Adsorptionsversuch mit Aktivkohle werden die Säuren entfernt, was den pH-Wert-Wechsel begründet.

Allgemeines / Geschichtliches zu Cola: Getränke spielen in der Ernährung eine wesentliche Rolle. Sie liefern neben der notwendigen Flüssigkeit andere wichtige Nährstoffe, wie Kohlenhydrate, Mineralstoffe und Vitamine. Täglich sollten mindestens 1,5 bis 2,0 Liter gleichmäßig über den Tag verteilt getrunken werden. Da pures Wasser auf Dauer etwas eintönig ist, haben die Menschen schon früh nach einer Alternative gesucht. In Italien war bereits im Mittelalter ein Getränk aus Limonen- und Zitronensaft bekannt, das sie "lemonata" nannten. Aber erst 1650 wurde in Paris die erste "Limonade" erwähnt. Und es dauerte noch zwei weitere Jahre, bis ein Verfahren entwickelt wurde, das die Sättigung von Wasser mit Kohlensäure ermöglichte. Um 1800 wurden in Dresden und Philadelphia, die ersten kohlensäurehaltigen Erfrischungsgetränke hergestellt. 1886 stellt der Apotheker Dr. John S. Pemperton in Atlanta einen Sirup her, der mit Sodawasser vermischt, zunächst gegen Kopfschmerzen und Müdigkeit gedacht war. Das Getränk, das unter dem Namen "Coca-Cola" bekannt wurde, ist heute das bekannteste und meistgetrunkene Erfrischungsgetränk auf der Welt. In den vergangenen 40 Jahren stieg der Verbrauch an Erfrischungsgetränken in Deutschland von 33 Litern auf rund 86 Liter pro Person, und das bei einem Gesamtgetränkekonsum von fast 210 Litern pro Kopf.

With Purple Gold and Bouncy Metal, a Canadian Chemist Shines on YouTube

Disillusioned with grad school, Nigel Braun dropped out to film chemistry videos in his parents’ garage in Montreal. Then millions began viewing his whimsical and occasionally dangerous experiments.

Reporting from Montreal

• Aug. 17, 2024

While he can’t turn water into wine, Nigel Braun is making vodka out of thin air.

He is neither miracle worker nor magician. His secret is chemistry, and he films his experiments inside a commercial-grade laboratory in Montreal and shares the videos on his YouTube channel. That’s where 6.5 million subscribers know him as NileRed , like the fluorescent chemical dye, a name he acknowledges sounds vaguely biblical.

Mr. Braun’s videos surged in popularity during the pandemic, reaching 2.5 billion views, and as his audience ballooned, so did his ambitions. His experiments — often whimsical, sometimes practical and occasionally dangerous — range from transforming paint thinner into cherry cola, to developing bulletproof wood, to making carcinogens from scratch.

Over the past decade, since dropping out of grad school, Mr. Braun, 32, has outgrown a hobby workshop in his parents’ garage and two other facilities, settling into a third lab large enough to rival some academic research spaces in Canada.

But Mr. Braun considers himself less a chemist or a science communicator in the vein of Bill Nye and MythBusters than an adventurer. “I want to have a journey,” he said. “I’m not interested in just conveying information.”

Part of his appeal is that he doesn’t care to make chemistry look easy or neat.

Some of the tasks he sets himself on are both epic and arduous, like his many attempts to make purple gold, an alloy of gold and aluminum that gives the metal a unique color, but whose recipe is only vaguely described in one line of ingredients in a patent.

That Time a Russian General Invented Clear Coca-Cola, and Pepsi had One of the World’s Largest Navies

Zhukov approached American General Mark Clark and asked whether it was possible to make Coca-Cola transparent so it looked more like vodka. Clark passed along the message to President Harry Truman, who in turn contacted James Farley, Chairman of the Coca-Cola Export Corporation, who confirmed that Zhukov’s request was indeed feasible. The classic reddish-brown tint of Coca-Cola comes from caramel colouring, and removing this from the recipe, said Farley, would have a negligible impact on the flavour.  So it was that in 1946 a Coca Cola bottling plant in Austria delivered the first 50-case consignment of colorless Bestsvetnaya koka-kola   or “White Coke” directly to Marshall Zhukov. The drink even came packaged in special straight-walled bottles with the Soviet red star printed on the cap to make it look even more like vodka. Under this guise, Zhukov was able to enjoy his beloved American sugar water under his superiors’ noses until his death in 1974.

But by that time Western soda had finally penetrated the Soviet market – though not in the form of Coca-Cola, but rather Pepsi. The story of how Pepsi came to the USSR begins at the 1959 US National Exhibition, a display of American arts, culture, and industry held in Moscow’s Sokolniki Park. On July 24, US vice-president Richard Nixon and Soviet Premier Nikita Khrushchev toured the exhibition together. Among the most memorable events of that day occurred when Nixon and Khrushchev stopped by a display of a modern American kitchen and began debating the relative merits of American versus Soviet industrial production. The so-called “Kitchen Debate” became a seminal cultural event in the Cold War and significantly boosted Nixon’s political career. The second memorable event occurred when Nixon and Khrushchev passed the Pepsi display and the Premier was handed a glass of the soda to try. Though Khrushchev initially noted that the drink smelled like shoe polish, he was apparently so taken by the flavour that he drank six full glasses. Photos of Khrushchev drinking Pepsi appeared in US newspapers the next day, and were soon featured in a number of Pepsi advertisements along with the slogan “Khrushchev wants to be sociable. Be sociable, have a Pepsi.”

But far from being a spontaneous event, Khrushchev’s encounter with Pepsi had been planned from the start. After Coca-Cola chose not to attend the Moscow Exhibition, the head of Pepsi’s International Division, Donald Kendall, spotted an opportunity to gain a foothold in Russia. His superiors were skeptical, however, so on July 23 Kendall approached Vice-President Nixon and asked him to bring  Khrushchev by the Pepsi display when they toured the Exhibition the next day. Indeed, it was Kendall himself who put the first glass of Pepsi in the Soviet Premier’s hand. Amazingly, the stunt worked, and negotiations began almost immediately to set up Pepsi bottling plants in the Soviet Union. And for scoring this unprecedented coup, in 1965 Kendall was made CEO of Pepsi.

The negotiations took more than a decade, but finally in 1974 the first Soviet Pepsi bottling plant opened at Novorossiysk in 1974. One of the main difficulties in hammering out the deal was that the Russian Ruble was a closed currency and could not be exchanged for American dollars. Instead, Pepsi and the Soviet Union resorted to barter, with Pepsi providing bottling equipment and drink syrup in exchange for the exclusive US distribution rights to Stolichnaya vodka. As a result of this arrangement, Pepsi became the first Western product to be marketed and sold in the Soviet Union, and by 1978 Soviet bottling plants were producing 216 million bottles – and Russian citizens consuming over a billion servings – per year. In 1988 Pepsi also became the first western company to advertise on Soviet TV, running a series of ads featuring Michael Jackson. This arrangement, however, began to fall apart when in 1979 the Soviet Union invaded Afghanistan and the US Government imposed a boycott on Stolichnaya.  In desperation, in 1989 the Soviets agreed to pay Pepsi in warships, providing a motley collection of 17 old submarines, frigates, cruisers, and battleships to be sold for scrap. This deal temporarily gave Pepsi the 6th largest navy in the world, and lead Donald Kendall to quip to Brent Scowcraft,  President George H.W. Bush’s National Security Adviser:

“We’re disarming the Soviet Union faster than you are!”

Pepsi’s unexpected breakthrough into the Soviet Union took their longtime rival Coca Cola by surprise, and it wasn’t long before Coke began vying for a share of that market. In 1979 Coca-Cola CEO J. Paul Austin leveraged his friendship with then-US President Jimmy Carter to gain an audience with Soviet leaders and negotiate the importation of Coke into the Soviet Union. Negotiations hit a snag when the US Government officially boycotted the 1980 Moscow Olympic Games, an event Coca-Cola had sponsored for decades. However, Austin argued that as a multinational corporation Coca-Cola was above politics and continued to sponsor the games regardless, in the process introducing the Soviet people to his own brand of fizzy freedom water. But due to its head start Pepsi continued to be the most popular soda in Russia until the collapse of the Soviet Union in 1991.

The late 80s and early 90s also saw the return of Marshall Zhukov’s clear soda, though this incarnation would be far more short-lived than the original. Riding the contemporary  “clear craze” that associated clear products with purity and health, in 1992 Pepsi introduced Crystal Pepsi, which like  Bestsvetnaya koka-kola was simply regular Pepsi with the caramel colouring removed. The product proved popular, earning Pepsi around $474 Million in its first year of sales. But once again, Coca Cola was watching…and scheming. Sergio Zyman, Coca-Cola’s chief marketing officer, hatched a scheme to kill Crystal Pepsi before it could gain a permanent foothold.

How’d they do it?

Thanks to the successful launch of Diet Coke, Coca-Cola had a diet drink on their hands that had more or less faded into obscurity- Tab.

Significant to Coca-Cola’s plans here was the fact that diet drinks in general at this time were not terribly popular and were otherwise generally considered something only women drank. In fact, this association was so strong that Tab cans themselves were made pink and advertisements eventually solely targeted women, with such statements as “Be a shape he won’t forget… Tab can help you stay on his mind.”

This negative association with diet drinks among half the population and a brand that Coca-Cola didn’t really care about got the wheels turning among executives at Coca-Cola, with the result being a rather ingenious idea to hurt sales of the upstart, Crystal Pepsi.

Launched as a direct competitor to Crystal Pepsi in December of 1993, Tab Clear was later described by former Pepsi executive and, at the time, head of marketing for Coca-Cola Sergio Zyman as a product the company intentionally sent to die, almost purely to spite Pepsi.

In a nutshell, this was just the exact same drink as Tab, sans caramel coloring. The company also removed the caffeine from the product- another move that isn’t terribly popular with consumers.

They then very prominently featured the fact that the product was caffeine and sugar free right on the can. Naturally, both being clear colas, most stores stocked Crystal Pepsi and Tab Clear very close to one another.

This all combined had Coca-Cola’s executives hoping consumers would similarly assume that Crystal Pepsi was a diet drink and caffeine free. If accepted by the public, these two factors would virtually guarantee that Crystal Pepsi would never be a mainstream drink, no matter how hard Pepsi tried to make it a thing.

In the end, Zyman called the launch of Tab Clear, “a suicidal mission from day one” and in an interview for the book, Killing Giants: 10 Strategies To Topple The Goliath In Your Industry gleefully noted,

“Within three or five months, Tab Clear was dead. And so was Crystal Pepsi.”

While Crystal Pepsi was temporarily re-released a handful of times in the late 2010s, it seems that the only person to ever enjoy the refreshing taste of clear cola long-term was Marshall Georgy Zhukov.

Cola is just nasty stuff. An addictive, sticky brown liquid that rots your teeth and wreaks havoc with your pancreas. Looks a bit like dirty motor oil and extremely cloying. It literally takes the rust off cars too. The way its so universally drank around the world is certainly something that would give aliens pause…..

Key concepts Chemistry Physics Materials science Carbonation Physical reactions Explosions Introduction Have you ever seen the Diet Coke and Mentos experiment that is all over the Internet and wondered what makes the reaction work? You might think that there is some ingredient in a Mentos candy that causes a chemical reaction with the soda pop, like the way baking soda reacts with vinegar. But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction are there, but that they are simply rearranged. It also means changing some factors may cause a larger or smaller physical reaction to take place. Background A carbonated beverage is packed full of dissolved carbon dioxide gas, which forms bonds with water. While the soda is in the bottle, the gas is kept in solution by the bottle's pressurized conditions. When you pour some soda into a glass, some gas escapes and forms foam, but most stays trapped by the surface tension of the water. But all those gas bubbles want to escape, making it no wonder that soda makes you burp! To create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide's bonds with water in the Diet Coke must be broken. A Mentos candy can help with this. Although the candy may look smooth, if you looked at it under a microscope you'd see tiny bumps coating its entire surface. This rough surface allows the bonds between the carbon dioxide gas and the water to more easily break, helping to create carbon dioxide bubbles and cause the classic eruption. The speed at which the Mentos falls through the soda can affect how large the eruption is, and this can be tested by comparing whole with crushed Mentos, the latter of which are less dense. Materials •    Wax paper •    Cutting board •    Knife •    One roll of Mentos (at least eight candies) •    Two index cards •    Tape •    Two two-liter bottles of Diet Coke •    An outdoor area at least two meters from buildings •    Eye protection (safety goggles or glasses) •    Video camera with either a tripod or a helper to take the images (optional) Preparation •    Place a piece of wax paper on top of the cutting board. On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. An adult may help you cut up the candies. What does the inside of the candies look like? •    Make a Mentos cartridge to hold the candies for you before you drop them into the Diet Coke bottle by rolling an index card into a tube, slightly larger than the diameter of a Mentos candy. Tape the tube together on the side. •    Be sure to wear eye protection when putting the candies into the cola! •    Wear clothes that you would not mind if they get splashed with a little soda pop—this activity can get a little messy! Procedure •    Place a Diet Coke bottle in an outdoor area, at least two meters from any buildings or anything hanging above the area, such as eaves, overhangs or wires. Make sure that the bottle is on a level surface and stably standing straight. Why do you think all of this is important? •    If you want to videotape the reactions, set up the video camera so that it has in its viewfinder the bottle and a height equivalent to at least the first story of a building. •    Carefully remove the cap from the bottle and place the flat index card on top, covering the hole. •    Add four whole Mentos candies to your cartridge, put on your eye protection, and start the video camera. •    Place your full cartridge on top of the flat index card. Line up where the opening of the bottle is with the opening of your cartridge. Quickly pull out the flat index card, releasing the Mentos candies into the bottle. Then step back without tipping the bottle over or disturbing the reaction. •    How quickly did the reaction start to happen, and how quickly did it stop? About how high did the eruption go? How much cola is left in the bottle? •    When the bottle stops spouting, stop recording. •    Remove the spent cola bottle and place a new full bottle in the same position, again making sure that it is level and stably standing straight. As with the first bottle, remove the cap and place the flat index card on top, covering the hole. •    Add your four crushed Mentos candies to your cartridge, pouring them in from the wax paper. Put on your eye protection and start the video camera. •    Like you did before, place your full cartridge on top of the flat index card, then line up where the opening of the bottle is with the opening of your cartridge. Quickly pull out the flat index card, releasing the crushed Mentos into the bottle, then step back without tipping the bottle over or disturbing the reaction. •    How quickly did the reaction start to happen, and how quickly did it stop? How high did the eruption appear to go? How much liquid is left in the bottle? Is it more or less than the amount that was left when you used whole candies? •    When the bottle stops spouting, stop recording. If you videotaped the reactions, you can watch your videos now. What do you notice from the videos? •    Which reaction went higher, the whole or the crushed Mentos? •    Extra : Find an exterior wall of a building with no windows and set a Diet Coke bottle at the base of the wall. Use a tape measure and blue painter's tape to mark off the height from the top of the bottle in meters. Then repeat this activity three times, with the bottle in front of the tape-marked wall, video taping it each time. When you review the recordings, use slow motion and pause the recording when the spout is at its maximum height. Using the tape marks in the background, estimate the height of the spout. Calculate the average height of the fountains for the whole and for the crushed Mentos . What is the difference in height of the eruptions? •    Extra: What other factors affect the size of the Mentos and Diet Coke eruption? You can try testing different kinds of carbonated beverages, different kinds of candies with different shapes and textures or using other things to start the reaction, like rock salt, pennies or dice. Which beverages, candies or other things cause the largest and smallest fountains? Why do you think this is? •    Extra: Do this activity again but instead of testing whole Mentos versus crushed, compare warm versus cold Diet Coke. Does temperature affect the eruption height? Observations and results Was the eruption higher when whole Mentos candies were used compared with crushed candies? Was less Diet Coke left in the bottle after the reaction with the whole candies compared with the crushed ones? In the Diet Coke bottle the Mentos candy provides a rough surface that allows the bonds between the carbon dioxide gas and water to break more easily, helping to create carbon dioxide bubbles. As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption. Because Mentos candies are rather dense, they sink rapidly through the liquid, causing a fast, large eruption. The crushed Mentos candies, however, are not as dense as the whole ones, which causes them to sink more slowly, creating a relatively small cola fountain, which should also leave more liquid in the bottle than the larger eruption with whole Mentos candies did. Cleanup Hose off any part of a building that was splashed with Diet Coke. If you try this project with regular Coke, the eruption should still happen but its sugary content may make cleaning more difficult.

Olympic swimmers are staving off E. coli by chugging Coca-Cola

Not only is Coca-Cola an official sponsor for the Paris Olympics, but it’s received ringing endorsements from some athletes. Olympic swimmers are chugging Coke after events because of its supposed ability to stave off bacteria and stomach issues—a real concern for those swimming in a heavily polluted Seine river.

“The myth of Coca-Cola is true,” Moesha Johnson, an Australian marathon swimmer, told the Wall Street Journal . “We will often have a Coca-Cola afterwards just to try to flush out anything inside of us.”

Other Olympians agree: A gulp of Coca-Cola after a dip in the Seine can be an elixir against stomach-irritating bacteria and viruses. Fizzy beverages have long been a home remedy for gastrointestinal distress, with the rationale being that bubbles settle the stomach and sugars in the drink replenish glucose. But doctors are lukewarm on the treatment, instead recommending natural anti-inflammatories like ginger in place of a sugar-loaded swig that can cause even more stomach upset. Some long distance runners, however, still swear by the drink to give a late-race boost of energy.

Coca-Cola was already on the rocks with health experts, who have accused the company of “ sportswashing ” sugary soft drinks, and environmental activists, who have criticized the company’s distribution of the drink in plastic bottles during games. Coca-Cola has said it offers sugar-free alternatives, and the Olympics Committee has stood by its partnership with the drinks brand.

But the soda’s supposed health properties aside, its popularity as a stomach-settling antidote has piled on concerns about the cleanliness of the Seine. Davey Jones, professor of environmental science and public health at Bangor University, told BBC Science Focus the river, which hosted the triathlon and swimming marathon events, is replete with odious microorganisms like bacteria and viruses. If the Seine contains E. coli, which is indicative of the presence of sewage or animal feces in a body of water, it likely also contains norovirus, the most common cause of gastroenteritis, which causes cramps, vomiting, and diarrhea.

“Whenever there’s sewage overflow, for example, into the Seine, norovirus gets released into the water,” Jones said. “You only need, in theory, to ingest one to ten viral particles to get sick. And when we’re sick, every time we go to the toilet, we emit trillions of these viral particles.”

E. coli’s Olympic mettle

The presence of bacterial and viral particles in the Seine have had an unwelcome spotlight leading up to and during the Olympics. At the beginning of the games, pollution in the Seine delayed the men’s triathlon by a day after officials canceled a training session for the event. Water tests showed elevated E. coli levels after a heavy rain storm. Two triathlete swimmers dropped out of competition due to illness, though neither linked it with swimming in the Seine. 

“For the moment, there is no direct link between the Seine and any illness,” Paris deputy mayor Pierre Rabadan said in a press conference Monday.

But concerns about the cleanliness of the Seine did not begin just prior to the Olympics. For decades, the river—a vital artery in the heart of Paris—has been considered a cradle for pollution. Like many old cities, Paris’s sewage system combines both sewage and stormwater, and after long periods of rain, waste doesn’t get treated before flowing into the Seine.

Though Paris has long promised a long term solution to the river’s pollution, an Olympic deadline pushed the project into high gear. The city invested $1.5 billion in cleaning the river before the games, a process that required building a massive underground basin for rainwater to be funneled to treatment centers before joining the river. Paris mayor Anne Hidalgo even promised to take a swim in the river after the cleanup efforts. But skeptics made their thoughts clear, with some threatening to hold a protest by defecating in the river ahead of the officials’ promised swim.

The post-Olympics future of the Seine is still in question. The city’s cleanup efforts were successful in allowing Olympic events to take place in the river, but spats of heavy rain still threaten safe water conditions. With climate change making extreme weather both more common and unpredictable, treatment of the Seine—and finding lasting solutions to pollution—promises to be a persisting issue. “The success will be complete if politicians and scientists keep up their efforts for the next few years,” Jean-Marie Mouchel, professor of hydrology at Sorbonne University, told Wired .

5 coolest experiments involving Coca-Cola

How to perform cool experiments with cola at home

Safe­ty pre­cau­tions

Don’t drink the Coca-Cola used in any ex­per­i­ments! Ob­serve safe­ty pre­cau­tions when work­ing with heat­ing de­vices.

Reagents and equip­ment

• bleach (15% so­lu­tion sodi­um hypochlo­rite);
• a rusty tool;
• fry­ing pans;

Step-by-step in­struc­tions

Diet Coke and Men­tos erup­tion

Toss a Men­to into a bot­tle of Diet Coke. Ob­serve the re­lease of gas and for­ma­tion of a spout of foam .

Coca-Cola and milk

Pour 50 mL Coca-Cola into 30 mL milk . Ob­serve as the milk cur­dles and the so­lu­tion pales.

Coca-Cola and rust

Let a rusty tool sit in 150 mL Coca-Cola for 5 hours. Re­move it from the so­lu­tion, wipe it off with a pa­per tow­el, and pay at­ten­tion to the dis­ap­pear­ance of the rust.

Cola and bleach

Add 20 mL bleach (15% so­lu­tion sodi­um hypochlo­rite) to 50 mL Coca-Cola. Ob­serve as the mix­ture pales.

How much sug­ar does Cola con­tain?

Pour 200 mL of clas­sic Coca-Cola onto a fry­ing pan. Heat un­til all the liq­uid evap­o­rates. Re­peat the ex­per­i­ment in a sec­ond fry­ing pan us­ing Diet Coke. No­tice the large quan­ti­ty of black tar from the clas­sic Coca-Cola.

Process de­scrip­tion

• Men­tos have a rough sur­face, which aids the for­ma­tion of a large amount of car­bon diox­ide gas from the Coca-Cola on its sur­face. Food ad­di­tives in the Cola and Men­tos con­trib­ute to the for­ma­tion of a large quan­ti­ty of foam.
• Milk con­sists main­ly of pro­teins, fats, mi­croele­ments, and wa­ter. When Coca-Cola is added, the phos­phor­ic acid it con­tains forces the milk to cur­dle. Mean­while, the form­ing clots of pro­teins drag col­or­ing mol­e­cules with them, caus­ing the mix­ture to pale.
• Rust con­sists most­ly of iron(III) ox­ide, and de­vel­ops on iron ob­jects due to hu­mid air or house­hold chem­i­cals. But it’s no prob­lem for clas­sic Coca-Cola! A rusty tool left in Coca-Cola will be thor­ough­ly cleaned from the unattrac­tive tar­nish. This hap­pens thanks to the phos­phor­ic acid in Coca-Cola, which dis­solves the iron(III) ox­ide. 2H₃PO₄ + Fe₂O₃ = 2Fe­PO₄ + 3H₂O
• Bleach con­tains sodi­um hypochlo­rite, which is a strong ox­i­diz­ing agent and eas­i­ly ox­i­dizes the col­or­ing mol­e­cules in the Coca-Cola, caus­ing it to pale.
• The main in­gre­di­ents of clas­sic Cola are sug­ar and wa­ter. As the wa­ter evap­o­rates, the mix­ture thick­ens and forms a black mass re­sem­bling tar, which main­ly con­sists of caramelized sug­ar. Diet Coke con­tains sug­ar sub­sti­tutes in­stead of reg­u­lar sug­ar. These sub­sti­tutes are much sweet­er than sug­ar – even be­ing added in tiny amounts, they make the drink ev­ery bit as sweet as the clas­sic ver­sion. As a re­sult, we see a much small­er amount of residue than in clas­sic Cola.

Wie viel Zucker enthält Coca Cola?

Sind coca cola und andere limonaden ungesund.

Wer kennt sie nicht? Die süße, leckere, prickelnde und erfrischende Limonade an einem heißen Sommertag.

Sicher läuft dir schon das Wasser im Mund zusammen. Aber Halt! Coca Cola und Co. tun deinem Körper und deiner Gesundheit leider gar nicht gut! Schon gar nicht, wenn du sie regelmäßig gegen den Durst trinkst.

Heute zeige ich dir deshalb in einem Video, wie viel Zucker in einer Flasche Cola steckt. Steckt in Coca Cola Zero (Zero steht für null Zucker) weniger oder gar kein Zucker? Ist es gesünder?

Schau dir zuerst einmal das Video an! 🙂

Erschreckend oder?

Hast du beobachtet, wie viel klebriger Zucker in der Pfanne mit normaler Cola übrig bleibt, wenn das Wasser verdunstet ist? Wenn du nun einen Liter Cola trinkst, dann nimmst du 35 Stück Würfelzucker zu dir. Das sind umgerechnet 106 Gramm Zucker auf einem Liter Cola!

Das tut deinem Körper und deiner Gesundheit gar nicht gut. 🙁

Aber wie sieht dies bei anderen Limonaden aus?

In diesen Getränken steckt ungefähr genau so viel Zucker wie in Cola:

• Capri-Sonne
• verschiedene gespritzte Fruchtsäfte

In diesen Getränken steckt mehr Zucker als in Cola:

• Verschiedene Pago Fruchtsäfte
• Coca Cola Vanille

Coca Cola Zero ist genau so süß wie normales Cola, weil Süßstoffe zugefügt wurden. Diese Süßstoffe sind Ersatzstoffe für Zucker, die meist noch süßer als Zucker schmecken. Es wird aber vermutet, dass Süßstoffe bei übermäßiger Einnahme Heißhunger auslösen können und den Geschmack verändern, wodurch sich der Geschmackssinn an die Süße gewöhnt und saure, bittere und nicht so süße Lebensmittel gemieden werden.

Was kannst du statt ungesunden Limonaden gegen den Durst trinken?

Als ideale Durstlöscher gelten:

• Wasser (am besten frisch aus der Leitung)
• Mineralwasser
• Kräuter- und Früchtetees (ungesüßt)

Natürlich ist es in Ordnung, hin und wieder süße Getränke zu speziellen Anlässen zu trinken, aber denk daran, lieber Wasser zu trinken, wenn du Durst hast! Du tust deiner Gesundheit etwas Gutes damit. Quelle: https://www.sipcan.at/getraenkeliste

Mach dein eigenes Experiment daraus!

Frag deine Eltern, ob sie dir dabei helfen würden, ein Experiment durchzuführen. Gehe wie im Video vor und erhitze mit deinen Eltern eine andere Limonade und schau, wie viel Zucker übrig bleibt!

Deine Viki 🙂

Die Kinder sollen …

• erkennen, wie viel Zucker in herkömmlichen Limonaden versteckt ist
• wissen, dass vermeintlich „gesunde“ Fruchtsäfte sehr viel Zucker enthalten
• lernen, dass Zucker nicht gesund ist
• gesunde Durstlöscher kennen lernen

The Infamous Coke and Mentos Experiment

September 11, 2014 By Emma Vanstone 1 Comment

The science experiments my children talk about for months afterwards are generally the messy ones, like our splatter patterns , glow in the dark oobleck ,  baking soda experiments and the well known coke and mento experiment .

If you try this classic chemis t ry experiment definitely do it outside as it’s VERY messy and sticky. Sometimes you’ll see it called a coke and mento geyse r, as the eruption looks like a geyser!

Coke and Mentos Experiment

You’ll need:.

Coke or other fizzy soda

Instructions

We dropped two Mentos into a bottle of normal Cola and Diet Cola. I used the cheapest brands available in our local supermarket.

Once you drop the Mentos into the coke, stand back as it’s VERY explosive. The trick is to drop the mento in as fast as you can. If too much of the fizz escapes before you add the mento the reaction won’t be as good.

What happens when Coke and Mentos mix?

There are several theories, but it’s thought that the many small pores on the surface of the mento speed up the release of carbon dioxide (CO 2 ) gas from the soda as they give a larger surface area for the reaction to occur over, causing foam to erupt at a super fast rate.

Which soda works best with Mentos?

Any fizzy drink will produce a similar effect, but diet drinks seem to work best, as we found in our investigation. This is most likely due to the particular chemicals in diet drinks.

The reaction isn’t a chemical reaction but a physical reaction! The molecules haven’t been chemically changed, just re-arranged!

See Steve Spangler for a much more thorough explanation of this very cool experiment .

Does the number of mentos affect the height?

More Mentos candies should mean a better explosion, but there is a limit to how many will actually make a difference. We found 7 to be the maximum number we could drop in at once.

More Coke and Mentos Eruption Ideas

Investigate to find out if the type of fizzy drink matters. Does diet soda make a taller geyser?

Try lots of different sodas and diet sodas.

Test fruit-flavoured Mentos instead of mint flavoured.

Find out if the number of mentos affects the height of the geyser.

Investigate to discover what would happen if you left the top off the Cola for a few minutes before adding the Mento.

Use the reaction to power something? Maybe a LEGO car?

Design a device to drop several mentos into the bottle at the same time. Can you find out what the optimum number of mentos for a 2-litre bottle of soda is?

Dem zucker auf der spur : ein trendthema - auch für den unterricht.

In zwei kompakten Unterrichtsstunden entlarven Kinder und Jugendliche die Namen für Zucker, werten die Angaben auf der Verpackung aus und hinterfragen ihren Zuckerkonsum.

• Unterrichtsmodul für die Jahrgangsstufen 5 bis 10
• thematisiert den versteckten Zucker in beliebten Produkten
• Zeitbedarf: eine Doppelstunde
• fächerübergreifend einsetzbar
• auch für spontane Vertretungsstunden geeignet
• vom Materialkompass des Bundesverbandes der Verbraucherzentralen mit "gut" ausgezeichnet

Ziel: Die Schülerinnen und Schüler wissen, hinter welchen Begriffen sich Zucker versteckt, können den Gesamtzuckergehalt in Lebensmitteln ermitteln und den eigenen Zuckerkonsum reflektieren.

Zucker und die versteckten Süßmacher

Ob beim Einkauf, am Kiosk, in Brotdosen, zu Hause im Kühlschrank oder Vorrat – fast überall locken süße Snacks, bunte Süßigkeiten, Süßgetränke, gezuckerte Milchspeisen und Fertigmüslis. Viele der süßen Produkte werben mit Aufschrift „zuckerfrei, zuckerreduziert oder weniger süß“. Da verwundert es nicht, dass Kinder und Jugendliche zu viel Zucker essen. Deshalb fordern Mediziner und Ernährungswissenschaftler: Weniger Zucker! Wenn Jugendliche diesen Empfehlungen folgen wollen, müssen sie die Süßmacher in Lebensmitteln erkennen, den Gesamtzuckergehalt einschätzen und für sich selbst konkrete Maßnahmen zur Zuckerreduktion entwickeln.

Das Thema im Unterricht

Im Unterrichtsmodul Dem Zucker auf der Spur steht Zucker sowohl unter gesundheitlichen als auch unter geschmacklichen Aspekten im Mittelpunkt. Die Schülerinnen und Schüler entlarven die Namen für Zucker, werten die Angaben auf der Verpackung aus und hinterfragen ihren Zuckerkonsum. Die kompakte Einheit ist direkt einsetzbar und enthält alles, was sich Lehrende für eine effektive Unterrichtsvorbereitung wünschen: relevante Hintergrundinfos, aktive Links zum Weiterlesen, veränderbare Arbeitsblätter und Infografiken. Damit eignet sich das kostenfreie Material auch für spontane Vertretungsstunden und eine fächerübergreifende Verbraucherbildung entsprechend den Bildungsplänen.

Ziel: Kinder und Jugendliche können den eigenen Zuckerkonsum einschätzen und bei Bedarf reduzieren.

Kompetenzerwartungen: Die Schülerinnen und Schüler

• arbeiten heraus, hinter welchen Begriffen sich Zucker versteckt,
• können den Zuckergehalt mithilfe der Nährwerttabelle ablesen,
• bewerten den Zuckergehalt beliebter Produkte und entwickeln Ideen zur Zuckerreduktion.

Zum kostenlosen Download beim BLE-Medienservice

Trendthema mit aktuellen Informationen

Das Unterrichtsmodul enthält alle relevanten Hintergrundinfos zum Thema Zucker sowie Links zum Weiterlesen und Hinweise zu Originalquellen.

Lebensnahe Arbeitsaufträge

Recherchieren, reflektieren, berechnen – in den schülernahen Arbeitsaufträgen verstecken sich viele Kompetenzbereiche.

Materialkarten

Zu jedem Arbeitsauftrag gibt es die passenden Materialkarten mit Produktabbildungen, Werbeaussagen, Barcode zum Scannen der Nährwerttabelle. Sie stehen zum Ausdruck oder zur digitalen Nutzung zur Verfügung.

Aufbau der Unterrichtseinheit

Einstieg: „Da ist gar nicht soviel Zucker drin – oder doch?“ Gemeint sind Ketchup, Knuspermüslis oder ein anderes bei den Schülerinnen und Schülern beliebtes Lebensmittel. Sie äußern sich zur Frage und aktivieren damit ihr Vorwissen über Zucker und dessen Kennzeichnung.

Qualitätsgeprüftes Material

Bewertung im Materialkompass lesen

Erarbeitung und Reflexion: Die Schülerinnen und Schüler erfassen den Infotext auf dem Arbeitsblatt „Zucker und die versteckten Süßmacher“. Dann erarbeiten sie im Plenum die Definitionen von freiem Zucker und Gesamtzucker, setzen sich mit Zuckerquellen auseinander und ergänzen Beispiele aus ihrem Essalltag. Nun reflektieren die Schülerinnen und Schüler ihren Zuckerkonsum. Sie untersuchen und bewerten selbst gewählte Produkte über die Angaben auf der Verpackung. Die Bewertung kann vorab im Plenum am Beispiel Joghurt erarbeitet werden. Der versteckte Zucker kann zusätzlich auch über Zuckerwürfel verdeutlicht werden. Die Erkenntnisse führen zur Frage nach den Handlungsalternativen.

Transfer und Anwendung: Im Plenum diskutieren die Schülerinnnen und Schüler ihre Lösungen zum Zuckersparen und beziehen dabei die folgende Aufgabe ein: Sina könnte z. B. nur einen halben Becher Fruchtjoghurt essen, ihn mit Naturjoghurt mischen oder in den Naturjoghurt frisches Obst schneiden. Welche Alternativen gibt es zu Knuspermüslis und süßen Softgetränken? Am Ende folgt der Impuls, dass beim Kauf neben Zucker auch Nachhaltigkeitsaspekte wichtig sind. Wie ist das süße Produkt verpackt, ist es ressourcenschonend und fair erzeugt?

Variationen, differenzierende Angebote : Die Zusatzfragen auf den Arbeitsblättern bearbeiten. Die Schülerinnen und Schüler

• hinterfragen und bewerten Aussagen wie „zuckerfrei“ und „ohne Zuckerzusatz“,
• vergleichen ein zuckerreduziertes mit einem normalgezuckerten Produkt,
• überprüfen ihre Bewertung mit dem Nutri-Score über die kostenfreie App „nutriCard –  gesünder essen“ (im Joghurtbeispiel auf der Materialkarte lässt sich der Barcode scannen),
• diskutieren über den ökologischen und sozialen Wert ihres Produkts.

E-Learning-Angebot zum Umgang mit Zucker

Wie Kindertagespflegepersonen und pädagogische Fachkräfte den Umgang mit Zucker verantwortungsbewusst gestalten können, ist Inhalt eines E-Learning-Angebotes, das das Bundeszentrum für Ernährung (BZfE) mit dem Nationalen Qualitätszentrum für Ernährung in Kita und Schule (NQZ) entwickelt hat. Das digitale Unterstützungsformat fasst Fakten zu Zucker, Zuckeralternativen und natürlichen Süßungsmitteln zusammen. Es erklärt, wie sich Zucker in Lebensmitteln erkennen lässt und wie Fachkräfte einen sehr maßvollen Umgang mit Süßigkeiten in Kita und Kindertagespflege gestalten können. Tipps für das Mahlzeitenangebot, die Zusammenarbeit im Team und mit den Eltern runden das Selbstlern-Tool ab.

Mit Sinnesschulungen Zucker bewusster wahrnehmen

Sinnesschulungen eignen sich, um auf die Süße von Erfrischungsgetränken, fertigen Müslimischungen und Milchprodukten aufmerksam zu machen und den Zucker bewusster wahrzunehmen. Damit regen SinnExperimente die Reflexion über stark gezuckerte Produkte an und bieten die Chance, die Neugier von Kindern und Jugendlichen auf weniger süße Alternativen zu wecken. So kann die Methode dazu beitragen, die Ziele der Nationalen Reduktions- und Innovationsstrategie für Zucker, Fette und Salz in Fertigprodukten des Bundesministeriums für Ernährung und Landwirtschaft (BMEL) zu erreichen und den hohen Zuckerkonsum vor allem bei Kindern und Jugendlichen zu verringern.

Lebensmittelqualität beurteilen.

Verbraucherbildung mit dem Qualitätsfächer

Schmeckt, Schmeckt nicht! Das ist ein Kriterium für eine Kaufentscheidung. Auch die Qualität von Lebensmitteln und Aspekte wie "klimafreundlich" und "ressourcenschonend" spielen eine Rolle.

Der Nutri-Score – was steckt dahinter?

Unterrichtsmodul für die Klassen 8 bis 10

Immer mehr Lebensmittel haben es drauf, das neue Nährwertlogo mit den bunten Stufen von A bis E. Was genau bedeuten die Angaben? Wo hilft das Label und wo liegen die Grenzen?

Was ist drin im fertig verpackten Lebensmittel?

Mehr Durchblick bei der Kennzeichnung

In diesem Unterrichtsmodul befassen sich Jugendliche mit der Pflichtkennzeichnung, der Zutatenliste und dem Mindesthaltbarkeitsdatum auf Verpackungen.

High-Protein

Muckis zum Löffeln?

Besonders Jugendliche kaufen sie gern: High-Protein-Produkte in Form von Quark, Puddings, Brot, Riegeln oder Pulver. Funktioniert das wirklich, mit der Extraportion Eiweiß?

How pepsi won the cold war, defeating coke in the soviet union.

MOSCOW, Russia - The Soviet Union was the only country in the world where Coca-Cola lost the market to its eternal opponent.

The Soviets first got acquainted with Coca-Cola in the 1930s, when an official delegation visited America. Colonizing the USSR with the iconic U.S. brand was deemed too expensive at the time, but there was an idea to set up production lines with completely different ingredients. Instead of coca leaves, Georgian tea was proposed. However, the new drink - Ruscola as it was dubbed - would never see the light of day.

After World War II, Coca-Cola had a chance to get inside the Soviet bloc thanks to a famous personality. Marshal Georgy Zhukov, one of the war's most famous Soviet generals, had developed a taste for Coke, after being introduced to the fizzy concoction by Allied forces commander General Dwight D. Eisenhower.

Zhukov, however, couldn't openly drink an American branded drink. He asked the company to create a special Cola, colorless like vodka, and not in such a "funny-looking bottle." Soon he got dozens of bottles of White Coke, topped with a red star on the crown cap.

Zhukov didn't try to promote Coca-Cola in the USSR, preferring to keep it for personal use only.

Coca-Cola seemed destined to enter the Soviet market - but old rivals PepsiCo were to beat the company to it.

In 1959, at the U.S. National Exhibition in Moscow, vice-president Richard Nixon did a favor for his friend, Pepsi CEO Donald McIntosh "Don" Kendall, and guided Nikita Khrushchev to the Pepsi stand. The Soviet leader was so amazed with the drink that he drank half a dozen glasses.

A photo of Khrushchev with a Pepsi cup covered the front pages the next day - giving the brand a massive boost. "Khrushchev wants to be sociable," echoed Pepsi's U.S. advertising of the time: "Be sociable, have a Pepsi." It was a big blow for Coca-Cola.

Negotiations to bring Pepsi to the Soviet Union took more than a decade: the drink only arrived in 1972, when PepsiCo started supplying concentrate and equipment for future factories. The first Pepsi plant opened in Novorossiysk on the Black Sea coast in 1974.

Monetising the drink proved more difficult. Soviet rubles were not traded internationally, since the Kremlin forbade currency exports. The solution was to use barter. Pepsi concentrate was swapped for Stolichnaya vodka and the popular spirit's U.S. distribution rights.

Coca-Cola bosses were horrified to see Pepsi become the first American brand to take root in the Soviet Union and jealous that the massive, potentially lucrative Soviet market was eluding them. Coca-Cola CEO J. Paul Austin parlayed his friendship with U.S. President Jimmy Carter to get direct access to Soviet leaders. As a result of their talks Coca-Cola finally came to the USSR. In 1979, limited quantities of fizzy orange drink, Fanta, appeared in Moscow, Kiev and Tallinn.

The Moscow Olympics of 1980 presented Coca-Cola with a golden opportunity. Although the U.S. declared a boycott of the games following the Soviet invasion of Afghanistan, Coke ignored it, pointing to the fact that it had been sponsor and partner of the Olympics since 1928. As a multinational company it was above politics, it added. Thus Coca-Cola became the main drink of the Moscow Games.

In 1986, Coca-Cola production finally began in the Soviet Union. Lada cars were swapped for the concentrate. It wasn't a profitable agreement, since it took three days to reconstruct each car before putting it on the European market. Coca-Cola bosses saw it as a loss leader and a way into the Soviet market, where they could take on their arch-rival Pepsi - and perhaps one day eject it.

With Coca-Cola's entrance into the Soviet market in the late 1980s, the struggle of the fizzy drinks behemoths heated up. PepsiCo was the first foreign corporation to start advertising on Soviet TV, with spots featuring Michael Jackson. Coca-Cola became the first foreign company to place an advertising banner on the roof of a downtown Moscow building.

In 1989, PepsiCo and the Soviet government signed an incredible barter deal, swapping concentrate for 17 decommissioned submarines and three warships, which the company sold for scrap.

"We're disarming the Soviet Union faster than you are," Kendall quipped to Brent Scowcroft, President George H.W. Bush's national security adviser.

After the fall of the Soviet Union, the two soda giants found themselves in a new world: instead of one closed Soviet market, they inherited a dozen new ones in former Soviet republics. The two corporations began a new battle to win the hearts and cash of potential customers.

Wie viel Zucker ist in Cola enthalten – und was ist der Unterschied zwischen Cola Light und Cola Zero?

Alles, was du über deinen täglichen Coca-Cola-Konsum wissen musst:

Zucker kann sehr heimtückisch sein – er lauert in unseren alltäglichen Lebensmitteln ebenso wie in unseren alkoholischen Getränken. Meistens merken wir nicht einmal, wie viel wir auf einmal zu uns nehmen. Sprudelgetränke sind die größten Übeltäter – oft mit einem sehr hohen Gehalt an verstecktem Zucker.

Es überrascht wahrscheinlich nicht, dass Cola zu den schlimmsten Übeltätern gehört – vor allem, wenn man bedenkt, wie oft sie schon in den Schlagzeilen war. Aber wie viel Zucker ist in Cola enthalten ? Und was ist mit den zuckerärmeren Alternativen?

Wie viel Zucker ist in normaler Coca-Cola enthalten?

Welcher zucker ist in cola zero und cola light enthalten, was ist der unterschied zwischen cola zero und cola light.

Flaschenkühlschrank Coca-Cola | 51 cm Höhe

Bereite dich auf ein paar ernsthafte Statistiken vor:

In der Regel enthält Cola etwa 10,6 g Zucker pro 100 ml . Das bedeutet, dass eine 330-ml-Dose etwa 35 g Zucker enthält – das entspricht etwa neun Teelöffel Zucker.

Eine 500-ml-Flasche enthält demnach mehr als 50 g Zucker und über 12 Teelöffel !

Eine einzige Dose Coca-Cola ist also bereits mehr als die tägliche Zuckermenge eines Erwachsenen. Schockierend!

Es gibt eine Reihe von kalorien- und zuckerreduzierten Alternativen zu normaler, vollfetter Cola.

Cola Zero und Cola Light sind die beliebtesten dieser Varianten.

Cola Zero enthält mehrere gängige künstliche Süßstoffe, darunter Aspartam und Acesulfam-K . Sie enthält weder Kalorien noch Zucker, hat aber dennoch den bekannten Cola-Geschmack. Cola Light hingegen verwendet kalorienarme Süßstoffe, um dem Getränk einen zuckerhaltigen Geschmack zu verleihen, ohne das süß schmeckende, lösliche Kohlenhydrat.

Obwohl zuckerfreie Alternativen scheinbar besser für unsere Gesundheit sind als zuckerhaltige Getränke , haben neuere Forschungen ergeben, dass diese Zuckerersatzstoffe komplexer sind, als wir vielleicht denken.

Als die ersten Diätgetränke in den 1950er Jahren auf den Markt kamen, waren sie zunächst für diejenigen gedacht, die abnehmen wollten. Die Forschung hat jedoch einen Zusammenhang zwischen Fettleibigkeit und künstlichen Süßungsmitteln festgestellt.

So ergab eine Studie, dass Menschen, die mehr als 21 künstlich gesüßte Getränke pro Woche tranken, ein fast doppelt so hohes Risiko für Übergewicht und Fettleibigkeit hatten wie Menschen, die diese Art von Getränken nicht konsumierten. In einer anderen Studie wurde festgestellt, dass der Konsum von Diätlimonade mit einem größeren Taillenumfang über einen Zeitraum von 9-10 Jahren verbunden war. Ein eindeutiger Zusammenhang ist jedoch noch nicht festgestellt worden.

Das bedeutet, dass Zuckerersatzstoffe möglicherweise keine eindeutige Lösung für diejenigen sind, die abnehmen wollen.

Das liegt an einer einzigen Zutat. Die Zutatenliste von Cola Zero enthält Natriumcitrat , die von Cola Light Zitronensäure , aber die beiden Getränke schmecken auch unterschiedlich.

Coca-Cola Zero sieht aus wie die klassische Coca-Cola und schmeckt auch ähnlich. Sie ist also eine gute Wahl für alle, die die zuckerhaltige Süße der Vollfett-Cola lieben, aber auf die neun Teelöffel Zucker verzichten wollen, die sie enthält. Cola Light hingegen enthält eine andere Mischung von Aromen, die ihr einen leichteren Geschmack verleiht. Sie ist vor allem bei Menschen beliebt, denen normale Cola ein wenig zu süß ist.

Manche Leute glauben, dass die beiden Produkte auch unterschiedliche Zielgruppen haben. Viele sind der Meinung, dass Cola Light – die in den 1980er Jahren auf den Markt kam – eher eine weibliche Kultanhängerschaft hat, während andere glauben, dass Cola Zero – die sich für eine maskulinere, dunklere Verpackung entscheidet – auf Männer abzielt .

Garage Library and the 0+ Space will be closed until August 30 for the installation of the project Open Storage: A Prologue.

DESCRIPTION

Art Experiment gives a new meaning to a day at the museum allowing visitors of all ages to experience culture in new ways.

Establishing new strategies in Russia for engaging with experimental art practices, each winter Garage Museum of Contemporary Art transforms its galleries into a laboratory for participation. Since it launched in 2010,  Art Experiment— the flagship program of Garage Education—has attracted over 25,000 students, parents, local residents, and Moscow visitors, making it the largest socially engaged art initiative in the country.

With a different theme each year,  Art Experiment  is structured through three daily sessions during which visitors of all ages are invited to have hands-on experiences with artists, as well as innovating creative collaborations between peers. In response to demand, in 2013 the initiative expanded from a two-day, to a three-week exhibition and Garage piloted Russia’s first training sessions for mediators, facilitating closer interaction between staff and broad publics to better understand visitor’s interests. Now, each morning session is dedicated to children with special needs, groups from Moscow orphanages, and students, while evening events include professional concerts and art-inspired holiday parties, welcoming new audiences and Garage regulars alike.

Opening on December 22, the fifth annual  Art Experiment  is titled  32 questions from Cage.  Using the queries from his 1958 lecture “Composition as Process” as a provocation, the exhibition highlights the spontaneity of music and the dialogues it gives rise to. Celebrating Cage’s interests in popularizing contemporary music,  Water Walk —a composition he wrote for television and first broadcast in 1960 on “I’ve got a Secret”—will be staged in Moscow for the first time, performed by prodigy musician and composer Dmitry Vlasik, as well as music school pupils he has trained. New commissions include the Institution of Unstable Thoughts, founded in 1996 in Ukraine, who have developed a site-specific installation exploring the audiovisual aspect of music, as well as Playtronica, a Moscow-based collective, who will create an installation to test melody on a tightrope, as well as holding workshops on transforming any object   into a musical instrument. Other artists also include Alexander Hnilitsky, SlackLabs studio, ::vtol::, Hello Computer, Baschet Soundsculpture Workshop, The Moscow Chamber Orchestra, MUSICA VIVA, and Moscow City Municipal music schools under the Moscow Department of Culture’s Office of Educational Programs support.

Reflecting the experimentation that underpins the entire project, this year Garage has also worked with recent architecture graduate Artem Slizunov who won a contest to design the  Art Experiment experience. This follows a tradition the Museum established in 2012 to support the development of young architects in Moscow through stipends and competitive projects, including Garage’s annual summer pavilion.

Featuring: The Institution of Unstable Thoughts, Alexander Hnilitsky, Playtronica, SlackLabs studio, ::vtol::, Dmitry Vlasik, interaction design studio Hello Computer, Baschet Soundsculpture Workshop from the University of Barcelona coordinated by Marti Ruids, The Moscow Chamber Orchestra MUSICA VIVA directed by Alexander Rudin, as well as children's orchestras and music schools under the Moscow Department of Culture's Office of Educational Programs.
