The way this reaction works is, when Diet Coke's carbonation bubbles get into the pores of the mentos, enough carbon dioxide is made which causes the many explosion that happens when they are combined ( "Mental Floss" ). I'm addicted to Crystal Pepsi: https://youtu.be/qEjy3dS6COs \"HAVE A CRYSTAL PEPSI DAY!\" - L.A. Cover the opening of the test tube with an index card or similar slim, small paper. Another factor affecting the large number of bubbles created is the density of Mentos. While we cant really know what kind of damage this kid may have done to his stomach, the results were fairly predictable. Shake and inflate. The question is whether this reaction would occur in your stomach. A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. * Just drinking fizzy water was fairly OK but made me cold to the extent of uncontrollable shivering. 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. This is because fruity Mentos have an extra coating of flavor which slows down the reaction time. Use the needle to thread the string through four Mentos, leaving a 10cm length of sting trailing off the Mentos Bundle. In comparison, diet cokes showed reduced reaction times. One enterprising group made a mentos and diet coke-powered rocket. Instead it is a physical reaction. Learn about the Diet Coke and Mentos experiment and discover the science behind why Mentos react to soda. I don't burp much, so I hold it in anyway. While science teachers have been dropping candies and mints into 2-liter bottles of soda for years in an effort to release all of the dissolved carbon dioxide, the Mentos and Diet Coke reaction became world famous in 2005. Was Coca Cola the only Soft Drink to Contain Cocaine? Surface tension is the bond between molecules in the liquid. Log in. 460 Words2 Pages. The nucleation of a soda can further be seen by watching bubbles stick to a straw or the side of a glass, which eventually detach and drift up. Are There Any Long-Term Health Risks Eating Mentos & Soda? Apparently, we were dead wrong, as the paper points out: The pH of the diet Coke prior to the reaction was 3.0, and the pH of the diet Coke after the mint Mentos reaction was also 3.0. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. The gruesome appeal of the combusted tot story kept the legend in circulation long after it had been repeatedly debunked and dismissed. Measurements of the pH of the Coke before and after the experiments showed that its acidity did not change, ruling out the idea that a simple acid-base reaction drives the fountains. Hold Bottle by top with one hand place around the neck so that the bottle is upside down. 1. -does pepsi max work as a substitute for diet coke? 124 lessons. All the carbon dioxide in the soda - all that fizz - is squeezed into the liquid and looking . This is the same thing that happens to any other container with volatile ingredients. When i inflate using pumps, Plavini and the like, i manage up to thirty litres equivalent at atmospheric pressure. Mentos dont only react with Coca-Cola. *Amazon and the Amazon logo are trademarks of Amazon.com, Inc, or its affiliates. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Not surprising from a fellow who doesnt think people actually buy Mentos casually. No Dude, they just make them for Coca-Cola experiments. Origins: Mentos, a candy that has a soft, chewy interior encased in a slightly hard shell, is no longer just for noshing on when combined with a carbonated beverage in a closed environment that. All the reactions took place in a bottle angled at 10 off vertical and the fountain trajectories were recorded on video. Additionally, we do not recommend using any chemical without reading theMaterial Safety Data Sheet (MSDS), which can be obtained from the manufacturer. Read all Stars Jamie Hyneman Sodium bicarbonate can throw your acid-base balance way out and kill you. Enrolling in a course lets you earn progress by passing quizzes and exams. The candy's shell is pocked with little nooks and crannies the beverage's carbon dioxide molecules are immediately drawn to, and the confection's relatively large surface area provides infinitely more such nooks and crannies (nucleation sites) than, say, an M&M would. As it does not have sugar so it will be easy to clean up the mess after experiment. The bubbles that appear on the surface of Mentos must then travel a further difference to reach the surface of the soda, giving them more time and space to disrupt the solution. The Coke-Mentos science experiment is certainly fun to do but its also messy, so we recommend doing it outside or in an easily-cleaned space, like a bath! Youll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. Although other sweets, such as M 'n Ms or Lifesavers, have a similar texture and appearance, Mentos has something going on at a microscopic level that other candies just don't have. Videos of those who have attempted such foolishness consistently show the subjects experiencing great physical distress in the aftermath of their ill-judged stunts. Log in here. The 6"5 Beachball, Helium balloon, heck whatever is here! Those who have disregarded common sense and tried such anyway report that the intensity of the reaction forces the mouth open, thereby releasing most of the gas and foam into the wild, as it were, rather than keeping them contained within the person. do with the outside." Coffey, T. Chalk doesn't dissolve in water, so it should provide nucleation sites without getting soggy. It is best to use the regular Mentos without extra coatings. We dropped two Mentos into a bottle of normal Cola and Diet Cola. Is it some sort of chemical reaction between Mentos and Diet Coke that is producing the explosion? This means that they sink to the bottom of the beverage. It is almost certainly not true that anyone has ever died from doing this. Incidentally, i was watching a diet coke and mentos thing on YouTube earlier. So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. Because these molecules are thus less likely to hold onto each other, the solution is easier to disrupt. Aluminum Foil: Should the Shiny Side be Up or Down When Cooking? For instance, in photosynthesis, water and carbon dioxide are transformed into sugar. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. When soda is poured into a glass, most of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface tension. When soda is made, manufacturers oversaturate a liquid drink with gaseous carbon dioxide. Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. This alert about an unnamed child in Brazil's sorry fate began circulating on the Internet in November 2006. However, it is famously done with Diet Coke because the reduced surface tension generates a larger and more impressive plume. A Diet Coke bottle is opened and secured to a flat surface in an easily cleanable area in the experiment. Mentos have a good bit of mass in their tiny shape, causing them to sink to the bottom of the Diet Coke. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? "This was a good project for my students to study because there was still some mystery to it.". Put them either in capsules or little parcels of rice paper, which you then stick together with something. 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 doesnt make the geyser any more impressive. Speed and pressure are also important factors in the explosivity of Coke fountains. * Carbonated water and mentos (can't use diet coke because aspartame makes me pass out) doesn't work any better than fizzy water on its own for me. also causes the carbon dioxide gas to be released. Dangerous (Do not drink Coka-Cola and eat MENTOS together)Last week a little boy died in Brazil after eating MENTOS and drinking COCA COLA together. Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. Thousands of microscopic carbon dioxide bubbles accumulate in these pockets, which then leaves gaps inside the bottle. [RAMUNE SODA FLAVORS], Will Soda Cans Explode in Checked Baggage? Diet cola of any manufacture is regarded as the liquid of choice for creating a "Mentos eruption" or "Mentos effect" because a cola's brown color serves to make the reaction much more starkly dramatic in all its explosive glory, and diet versions of those sodas don't leave the same sticky residue that their sugared counterparts do (an aspect well worth considering when contemplating spraying a wide area that you may afterward be called upon to clean). The gas form of carbon dioxide bonds with the water molecules present in the cola. Ok, so I was curious about this as well. The Diet Coke and Mentos experiment results from an increased rate of nucleation. A mint-flavored mentos makes a geyser 5 meters high and a fruit-flavored mentos makes a geyser 2 meters high when the two candies are put into identical bottles of soda under identical experimental conditions. The force exerted by the soda stream can be harnessed to do work. Measurements showed that the surface tension in water containing the sweetener aspartame is lower than in sugary water, explaining why Diet Coke creates more dramatic fountains than sugary Coke. That year, the grist being run through the rumor mill included the sad tale of a misadventuring tot who had gulped soda and ingested Pop Rocks, a carbonated candy known for producing a fizzling sensation in the mouth. Ok, so i was wonderin about coke and mentos inflation. Copyright 2023 @ Sodoapopcraft.com Watson-Publishing Limited Co. Telephone: +441414590217 Email: [emailprotected]. When the Mythbusters performed this experiment, even dumping the contents of a Mentos and Cola fountain directly into the stomach did not cause it to burst. This uneven texture provides a perfect surface to disrupt the solution and serves as an excellent attachment point for nucleated bubbles of gas. Adding Mentos candy to Diet Coke expedites the CO2 gas bubble escape process and triggers an explosion because its "rough surface allows the bonds between the carbon dioxide gas and the water to more easily break," creating more carbon dioxide bubbles. 2. But the rough coating of the candy begins to dissolve the moment you eat it. Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle. Thus, the texture of Mentos alone increases the rate of nucleation. No evidence was ever found that this story was true. Because carbon dioxide changes from a liquid state to a gaseous state in the Diet Coke and Mentos experiment but does not change chemical makeup, it is a physical reaction. In an . They are a pain in the ass to make, though. People will do anything for YouTube views, so you can watch a dimwit do this experiment here. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Diet Coke will work better than regular Coke for this experiment. much more than one liter could give me on its own. [2]. Experiments in a 2006 edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke. Bottled sodas are kept under pressure so that more carbon dioxide can be forced into solution. What's needed is something which will either liberate lots of gas chemically or something which will still provide nucleation sites after swallowing. A yard or large patio (without furniture nearby) with a sturdy, flat surface will work great. Its like a teacher waved a magic wand and did the work for me. It's possible that the twitches and the tingling i got were psychosomatic, of course, but it seems to me that if i just use calcium carbonate and fizzy water the situation is a lot more controllable because i don't have to think about all the other stuff. Answer (1 of 7): No. The team also investigated the total mass lost in the fountain and the influence of the sweet's surface roughness. Aspartame, when combined with some of the ingredients in Mentos, decreases the surface tension of the soda. So, in a nutshell (or, more aptly, a Mentos shell), soda mixtures with more sugar in them are more viscous, making their reactions less powerful. Students in Dr. Tonya Coffey's Appalachian State University's physics class tested the science behind the volatile Mentos/Diet Coke reaction, publishing their results in the American Journal of Physicsin 2008. The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. I was snorting gum out of it for hours afterwards. Sign up, Existing user? If you tried to swallow the foam as is emerged from the bottle, you might well vomit because of all the gas you swallowed, but you most certainly would not die Picture: By Michael Murphy - Mich. wowee zowee. Take the geyser tube and put all the mentos in it from the packet. 2. Turn on desktop notifications for breaking stories about interest. And if you add a big enough surfactant, you get a geyser. Then. In this case, ice melting into water is a physical reaction. New user? Diet coke and mentos are both calorie-rich drinks, which can contribute to weight gain. Further versions of the story specified the deceased youngster was the taciturn "Mikey" of LIFE cereal commercials. I vaguely remember that episode. This is essentially speeding up the process that makes sodas fizzy. Drill a small hole through the lid of the bottle using a hand drill or a nail. If you have health and safety related questions, visitHSE.gov.uk. However, the Coke and Mentos experiment does not only involve a physical change. how can they do it then? This is the same thing that happens to any other container with volatile ingredients. But, any carbonated beverage works. Place the soda bottle outside in and area that can get dirty. Just it's structure. Try it at home and see how Diet Coke and Mentos react. Diet Coke, a sugar-free cola beverage, and Mentos, a chewy round candy, are combined to generate a Diet Coke and Mentos eruption. anyways no expanding tummy as of yet. this big guy just dropped another BOOMIN video so like it up. It is a physical reaction rather than a chemical one. They are typically sold in rolls which contain 14 mint . They are covered in bumpy craters, which increases the total surface area. Soda geysters, which can reach as high as ten meters, were a popular subject for viral videos in the early 2000's, but the science behind the spectacle remained a mystery until 2008. Second, even if one did get a strong reaction to eating and drinking Mentos and Diet Coke at the same time, you'd likely just quickly vomit up the foam, which there have been numerous recorded instances of. Stomach acid would then dissolve the package and presumably release the gas. Mentos are denser than Diet Coke. Its relatively easy to do because the materials are readily available: with nothing but a few Mentos and a bottle of Coke, you can trigger an immediate, explosive reaction, making this a very simple yet very fun (if slightly messy) experiment. Almost everyone in middle school or high school has heard the urban legend: if you drink Coke and eat Mentos, youll explode! So, when a Mento is dropped into some Coke, the acidity of the soda mixture quickly dissolves its shell, releasing the chemicals. Since 2005 the Coke & Mentos reaction has been wow-ing children and adults everywhere - when it goes well! This is complete nonsense! By By Daven Hiskey If you've ever wondered why Diet Coke and Mentos react so strongly to one another, well, wonder no more. 3. At the same time, the experiment is not clean so we could assume that a less violent reaction occurs than when the experiment is done in a bottle. After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. Acids and bases are common classes of chemicals that react with each other and with water. essentially cause a lot of the carbon dioxide trapped. Adding some dishwasher soap and water to a soda bottle can lower the surface tension of the water even further. Mentos are then added to the solution, and the observers can stand back and watch a geyser form. a popular reaction:. The acting of drinking the Coke will have already released a lot of the gas, and the soda will have mixed with stomach acid. What type of physical reaction is Coke and Mentos? This is where the carbon dioxide in the pop goes to the mentos (EpyBird.com), and create a bubbly stream that had so much pressure it shoots out of the container. Inflation from diet coke and mentos can cause an increase in blood pressure, heart rate, and body The MythBusters performed just such an experiment using a pigs stomach. You could use a dry mixture of two powders which generate carbon dioxide when they dissolve in water. She is also certified in secondary special education, biology, and physics in Massachusetts. The famous Mentos-Coca-Cola reaction is a phenomenon known as nucleation. So, myth busted. Next, get ready to drop your Mentos into the Diet Coke. An experiment on Seltzer water, adding various types of solutes, produced the following results: Coca-Cola isnt a single chemical compound but rather a mixture of different chemicals. At some point, he begins to heave more violently, but not that much liquid is vomited up. The mints are small oblate spheroids, with a slightly hard exterior and a soft, chewy interior..
