Mentos are fairly dense objects and so tend to sink rapidly in the liquid. At the end of the 1990s, the manufacturer of Wintergreen Lifesavers increased the size of the mints and they no longer fit in the mouth of soda bottles. boredville.com. 1 decade ago.  Steve Spangler's televised demonstration of the eruption in 2005 became popular on YouTube, launching a chain of several other Diet Coke and Mentos experiment viral videos. Occasional vomiting from sickness or a stomach bug is normal, but forcing yourself to throw up soda and candy at every party is a one-way ticket to extra complications. You can see the results of this yourself by crushing a Mentos and dropping it into a bottle, then comparing the reaction to the whole candy with all its pores intact. Like most chemical reactions, the process occurs more quickly at a warmer temperature. Now, imagine you drink a can of soda very very quickly. Put a funnel or tube into the spout. Although I’m sure thousands of people (okay, 8th graders) have tried it, you just can’t turn your body into a human volcano with erupting geysers of diet soda. Protected by fear, few kids actually end up attempting the stunt, even to prove their guts to their peers. It was reported that a guy died in Brazil when he used mentos and coke together. The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released. © 2020 Copyright Soda Pop Craft - Make Your Own Soft Drinks At Home, link to Can Gatorade Give You Diarrhea? The reaction is caused by a process called nucleation, whereby the carbon dioxide in the soda is … However, any type of carbonated soda can be a replacement for Coca-Cola; the key is carbonation more than anything else. All of the tiny pores on a Mentos’ surface break the polar bonds between the carbon dioxide and the water, which is why any Mentos candy with a smooth surface fails to produce any reaction at all.  The Diet Coke and Mentos geyser experiment became an internet sensation in September 2005. Pre-existing bubbles provide a way for the reaction to occur without requiring bubbles to form within the liquid itself (homogeneous nucleation). CrerateSpace Independent Publishing Platform. Mentos candies contain millions of cavities, roughly 2-7 Î¼m in size, that remain unwetted when added to a soda. The rest of the process happens thanks to the physical properties of Mentos. If this were the case, eating Mentos and drinking soda may indeed be dangerous. This is the same thing that happens to any other container with the volatile ingredients. In order to understand why Coke and Mentos react so explosively, you have to understand how both ingredients work in the first place. Mentos candies typically have gum Arabic and gelatin in their formulas. Mentos are fairly dense objects and so tend to sink rapidly in the liquid.  When the pressure is released from a soda bottle upon opening it, dissolved carbon dioxide can escape into any tiny bubble located within the beverage. Your stomach is surrounded by many other internal organs that shift normally when you eat a large meal. H Regular soda uses sugar or corn syrup to derive most of its sweetening flavor, but diet soda eschews these ingredients in the name of fewer calories and better health. Mentos that drift peacefully through the soda will have a weaker reaction in comparison. You’ll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. Science teachers found that Mint Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. The investigation in the matter proved the cause to be real. ↽ While there are many stories of people dying from suddenly exploding due to the rush of carbon dioxide expanding in their stomach, none of these stories are factually true and no video footage has ever been recorded of such an accident. All of these tricks help to improve the speed and drama of a Mentos eruption. I'm a soft drinks enthusiast amd I'm bringing you all I know and research from the world of Soda Pop & Kombucha soft drinks. This doesn’t always cause a geyser to erupt out of a coke bottle; for instance, a Mentos candy cut into quarters will produce less of a reaction than a full candy. Are There Any Long-Term Health Risks Eating Mentos & Soda?  When dissolved gas diffuses into bubbles that already exist in a liquid, it is called Type IV bubble nucleation. But the rough coating of the candy begins to dissolve the moment you eat it. Lower surface tension makes it easier for the bubbles to break out to the surface and attempt to escape. It is likely that these stories are exaggerated and have been spread on the Internet for entertainment purposes. But the bubbling you’ll feel on your insides isn’t easy or gentle, so it shouldn’t be performed regularly. This effect can be maximized to a certain extent by adding a few Mentos candies to a given soda bottle, although there is a breaking point where adding more candies doesn’t make the geyser any more impressive. Eatings softmints and Coke will NOT cause any harm whatsoever. The physical characteristics of Mentos (surface roughness) have the effect of drastically reducing the activation energy for carbon dioxide bubble formation, so that the nucleation rate becomes exceedingly high. Since the escaping gas either comes out in the form of a long burp or in foam that’s expelled through vomiting, the issue basically stops once the soda has evacuated your stomach in one way or another. However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. These ready-made bubbles (which are nucleation sites) exist in things such as tiny fibers or non-wettable crevices on the sides of the bottle. O  It has been claimed that gelatin and gum arabic in the Mentos candy enhance the fountain, but experiments have shown that these candy additives have no effect on the fountain. Thankfully, there’s already a well-known escape hatch located at your mouth. Other soda types will work but Diet Coke seems to work the best (sugar molecules in regular sodas help keep the carbon dioxide in solution, slowing the reaction). Almost everyone in middle school or high school has heard the urban legend: if you drink Coke and eat Mentos, you’ll explode! Therefore, diet soda is better than regular soda if you want to make the biggest Mentos foam geyser possible. A Mentos has many, many fine scratches on the surface; a perfect place for bubbles form. You can also increase the effect by adding extra ingredients to a given soda.

", "Orchestrated Chaos: A Mentos Tribute to Eepybird.com", About.com Chemistry page with instructions, "Watch Scientists Conduct the Mentos and Diet Coke Experiment at 14,000 Feet", "Diet Coke and Mentos: What is really behind this physical reaction? Drop a few Mentos into a two-liter bottle of soda, and a geyser of foam erupts rapidly, sometimes reaching heights of 15 feet or more. A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle's base. Thus, you may simply wind up with a bad case of indigestion, or feel nothing at all. i already saw this on the site, and its so lame. You might think that there is some ingredient in a Mentos candy that is causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. Analysis: There have been many messages and videos like these warning not to eat Mentos before or after drinking Coke or Pepsi, especially with Diet Coke, claiming that the mixture will generate a chemical reaction forming Cyanide, which will ultimately explode your stomach. BIBLIOGRAPHY: Diliberto, J. As previously stated, the surface of Mentos candies is what makes this reaction work. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle. , Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. … The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. Overall, there’s no need to worry if you’ve done this once or twice before on a dare from a friend. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. So it is very important that this shaking in compressed air cars doesn't cause a reaction like Mentos and Cola do when put together.  Thus, the geyser reaction will still work even using sugared drinks, but diet is commonly used both for the sake of a larger geyser as well as to avoid having to clean up the stickier residue left by a sugared soda. As an Amazon Associate I earn from qualifying purchases. CO I'm not precisely sure as to what the explanation is for the reaction, but i"m pretty certain you're not going to explode. • Also, none of the ingredients in Mentos are basic: sugar, glucose syrup, hydrogenated coconut oil, gelatin, dextrin, natural flavor, corn starch, gum arabic. Finally, making your soda bottle warmer instead of colder will make the geyser higher and faster. − The basic science of the Coke and Mentos reaction is fairly straightforward. So you won’t get the same reaction in your stomach. The activation energy for bubble nucleation (formation of bubbles) depends on where the bubble forms. Mentos’ ingredients also help this reaction to some extent. Stand the diet coke bottle upright and unscrew the lid. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle. But the process is constant and grows exponentially. The rough surface of the candy creates friction where the heavier carbon dioxide molecules can sink and break away from their bonds with the water surrounding the. [Side Effects], link to What Flavor is Cool Blue Gatorade?  The foaming is aided by the presence of food additives such as potassium benzoate, aspartame, sugars, and flavorings in Diet Coke,  all which influence the degree to which water can foam. The activation energy for the release of carbon dioxide from Diet Coke by addition of Mentos has been found to be 25 kJ molâ1. What are mentos-diet coke effects on human body? Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. If you crush the Mentos, so it doesn’t sink much at all, you won’t get nearly the dramatic reaction. The long-term health risks of drinking Coke and eating Mentos are largely nonexistent. Hiskey, D. (2013, February 6). ) Drinking too much of any soda or sports drinks can lead to all manner of ill effects, and especially for those with any sort of pre-existing health issues or food intolerances. ( Yet another factor that can affect the size of the Mentos / Coke geyser is the temperature of the soda itself. Coke and Mentos Experiment.
