The force exerted by the soda stream can be harnessed to do work. This doesnt 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. 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. I was snorting gum out of it for hours afterwards. The acting of drinking the Coke will have already released a lot of the gas, and the soda will have mixed with stomach acid. Coke and Mentos Reaction Lab Ingredients in the Mentos and Diet Coke and, more importantly, the structure of the Mentos, allow carbon dioxide bubbles to form extremely rapidly. 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. This forces the liquid to overflow and shoot out. Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. It turns out Mentos were the best seeders for the reaction. However, this stomach did swell up a lot which would probably result in vomiting, just as we saw in the YouTube video. Why is Diet Coke a better choice for this experiment than other sodas? It certainly wont be comfortable and Mentos, but there arent any real health risks from doing so. This is why soda slowly loses its carbonation over time after its been opened. "These ingredients reduce the work required for bubble formation, allowing carbon dioxide to rapidly escape from the soda,"Coffey and her students found, after comparing the "contact angle for aspartame and water in contrast to pure water or sugar water.". Lower surface tension makes it easier for the bubbles to break out to the surface and attempt to escape. Search Pepsi Girl + Mentos. These bubbles form because of a disruption in the solution. Why does the reaction happen? This material may not be reproduced without permission. do with the outside." Invert the test tube, holding the cover in place. Or actually I can say whenever I buy a coke/pepsi I ask for a roll of mentos from the seller. Read all Stars Jamie Hyneman You can always add more Mentos for a bigger effect. When analyzing my new approach to this time . However, none of the ingredients in mentos are basic, and the experiment works to some degree with any type of soda and any type of candy. When mint or fruit Mentos are dropped into a fresh bottle of Diet Coke, a jet of Coke whooshes out of the bottle's mouth and can reach a height of 10 metres. The sudden swell of carbon dioxide inside your stomach will need an escape. A study in the US has identified the prime. Diet coke has 135 calories in a 12 fluid ounce serving, while mentos has 90 calories. They are covered in bumpy craters, which increases the total surface area. Create an account to start this course today. Mentos ingredients also help this reaction to some extent. If you looked at it with a microscope, it would look pitted, just like a golf ball. Carbon dioxide is the force that pushes the liquid out of the bottle in a fraction of a second. When Mentos react with Coca-Cola, the following reaction is explosive, rapidly forming a fountain of pressurised Coke that then spurts out of the bottleneck and shoots into the air. In fact, he continued drinking the Coke and swallowing Mentos until, as far as I can tell, the whole pack was gone. The nucleation reaction causes the rapid release of the carbon dioxide from the water, resulting in carbon dioxide gas which rapidly expands in the soda, pushing the liquid out of the bottle. I'm a guy. Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, Science Behind Mentos and Diet Coke Experiment, How to Turn Milk into Plastic - Science Experiment, FTCE Middle Grades General Science 5-9 (004) Prep, ILTS Science - Physics (116): Test Practice and Study Guide, Glencoe Chemistry - Matter And Change: Online Textbook Help, Middle School Life Science: Homework Help Resource, Explaining & Analyzing Physical Structures in Biology: Practice Problems, Medicinal Chemistry: Definition & Research, Absorption Spectroscopy: Definition & Types, Lanthanide Contraction: Definition & Consequences, What is Aerogel? I feel like its a lifeline. The short answer is that eating Mentos by chewing them up while drinking Coca-Cola, or any other soda, will little to no effect. Creatine can be taken as a supplement to help improve athletic performance and increase muscle mass. Mentos are then added to the solution, and the observers can stand back and watch a geyser form. 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. But what is the science behind this thrilling visual display? Combine Diet Coke and Mentos, and the result is explosiveDiet Coke shoots out of the bottle like a miniature, sticky Old Faithful. Materials: 1 pkg. Why or why not. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. So, any rough surface inside the bottle will cause the carbon dioxide molecules to cluster together in a process called nucleation, which forms bubbles. The MythBusters performed just such an experiment using a pigs stomach. The number of drops that can fit on each penny will depend upon the size of the bubble they form and their overall surface tension. However, most of the carbonation is released from the soda as it is being drunk, so the pressure is lower and carbon dioxide is less likely to nucleate. It's true that most of the people that do it do indeed inflate from simply having that much soda in them, but if you can hold the gas down I don't think there's anything stopping you from inflating. These microscopic irregularities on the Mentos surface serve as nucleation sites where carbon dioxide bubbles form. The other thing that happened was that the gas came straight back up and made me belch huge clouds of powder. Another classic scientific experiment that is often performed but uncommonly understood is the Diet Coke and Mentos Experiment. Is the How Coca-Cola Reacts to Stomach Acid Video Real? Diet Coke makes a better spectacle than regular Coca-Cola because both aspartame and benzonatate (a preservative used in artificially sweetened drinks) lower surface tension more than sugar does. When soda is made, manufacturers oversaturate a liquid drink with gaseous carbon dioxide. Mentos that drift peacefully through the soda will have a weaker reaction in comparison. So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. Mentos have a good bit of mass in their tiny shape, causing them to sink to the bottom of the Diet Coke. As it does not have sugar so it will be easy to clean up the mess after experiment. Drop your Mentos in the Diet Coke and step back - it's about to get messy! It is likely that these stories are exaggerated and have been spread on the Internet for entertainment purposes. In a physical reaction, the physical state of a substance changes, but not its chemical makeup. You can expect a large eruption. Of course, this is for YouTube, so he continues drinking and swallowing candy. Additionally, the stomach has a couple ways of expelling excess gases. The chemical reactions involved in dropping mentos candies into a bottle of diet coke make quite the spectacle! Inflation from diet coke and mentos can cause an increase in blood pressure, heart rate, and body Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the Coke. Either way, it's funny. Course, it could be just the soda inflating me. (2008). Mentos are a brand of packaged scotch mints or mint flavored candies sold in stores and vending machines.First produced in 1932, they are currently sold in more than 130 countries worldwide by the Italian-Dutch corporation Perfetti Van Melle. They, too, concluded that the "surface roughness" of the Mentos is "one of the main causes of the reaction. It doesn't matter if the liquid contains sugar or not. Any Mentos in the soda will eventually cause all the carbon dioxide to become gaseous and escape the bottle; the only difference is in how fast and how explosively it occurs. The hands-on experiment involves dropping several Mentos Chewy Mints into a bottle of Diet Coke, which can cause a stream of the diet cola to shoot many feet into the air within seconds. The Mentos' surface area is conducive to carbon dioxide nucleation from the solution. The YouTube video discussed above is not exactly scientific, however. When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. this big guy just dropped another BOOMIN video so like it up. 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. When taken with fruit juice, creatine is more easily absorbed by the body. If you down a large amount of soda, the carbon dioxide is released. You want to be careful about that. This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. Your membership is the foundation of our sustainability and resilience. A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. Mentos has thousands of tiny bumps over its surface even though the candy might look smooth to the naked eye. It causes me no vomiting as well as no. Effects of diet coke and mentos on the body. The Diet Coke and Mentos reaction is a common experiment performed in many science classes. Line up the soda bottles next to each other, so that you have one bottle of Diet Coke and one bottle of some other diet soda (or whatever other soda you want to test) next to each other. No evidence was ever found that this story was true. Aluminum Foil: Should the Shiny Side be Up or Down When Cooking? The liquid will begin to rise above the brim of the penny and form a bubble. I'm probably being pessimistic about it. 2. If drops are continually added, this bubble will grow and continually burst, spilling water down the sides of the glass. Like many, I'm a HUGE soda drinks fan and have an obsession with making, testing, and trying the myriad of flavors and brands from across the world. The "child who died from combining Mentos and Coca-Cola" story is an updating of an older legend that began in 1979. If your eruption wasn't everything you'd hoped for, make sure you have fresh ingredients. This is because as they rise, they disrupt the solution on their way to the surface, allowing more carbon dioxide to escape from the solution. Your stomach will not explode. But i think nucleation sites are the way to go, not an actual chemical reaction. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual. There are many other factors that can affect the height of a soda fountain when Mentos react with Coca-Cola, such as the viscosity of the liquid and presence of other chemicals in the mixture. 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. Diet Coke has an artificial sugar called aspartame that reduces its surface tension capabilities. Diet Coke and Mentos - . The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. However, the American Chemical Society provides step-by-step instructions on how to safely make a Mentos soda fountain, so this is one experiment you can try at home. coke geyser. How To Get Rid of White Spots on Stainless Steel Pans. The reaction is caused by a process called nucleation, whereby the carbon dioxide in the soda is attracted to dozens of tiny pores on the surface of the Mentos, causing so much pressure that the . * 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. ", 24/7 coverage of breaking news and live events. 2. The Coke-Mentos experiment is one of the most popular science experiments and also one of the most well-known. So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. Place the soda bottle outside in and area that can get dirty. Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. -does pepsi max work as a substitute for diet coke? What is the most reasonable hypothesis to explain the difference? Still not quite getting it? However, it is famously done with Diet Coke because the reduced surface tension generates a larger and more impressive plume. The reaction is so intense, you can make a rocket propelled by . Documentary Mystery Reality-TV Jamie and Adam try to scientifically explain the recently publicized and highly entertaining chemical reaction caused as a result of placing a Mentos candy into a 2-liter bottle of Diet Coke. also, i had to lay down to hold in the gas. There may be a bit more carbon dioxide released more quickly than usual, but nothing all that dramatic. The two biggest factors affecting the geyser are the roughness of the candy used and the rate at which it sinks to the bottom of the soda bottle. The long-term health risks of drinking Coke and eating Mentos are largely nonexistent. There is an urban legend that eating mentos while drinking soda could cause a person's stomach to burst. The gruesome appeal of the combusted tot story kept the legend in circulation long after it had been repeatedly debunked and dismissed. Does Diet Soda Make a Difference With Mentos? The effect it has on your acid levels is minimal, as long as you don't over do it (which is true for most things). Protected by fear, few kids actually end up attempting the stunt, even to prove their guts to their peers. As a result, they are important biologically, industrially, and environmentally. This experiment is an example of a physical reaction (which changes the state of a substance), not a chemical reaction (which changes the chemical makeup of a substance). Step 3: Shake and Launch! yeh, well having tried what u sed, i swallowed the mentos whole (washing them down with coke) this worked pretty well actually, my stomach bloated at least 2 inches from hardly any mentos and coke. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. Furthermore, dropping the Mentos into the soda bottle with force to make it descend quickly will force more carbon dioxide through its small pores and make a faster reaction were more bubbles are created in a short amount of time. Put it on the bottle in such a way that all the mentos in the tube are . Open the soda and place the index card over the bottle opening. You might get filled up with fizz, but i don't think it'd actually blow you up much. 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. We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites. * Citric acid and bicarbonate of soda should release lots of carbon dioxide. Acids also . you got good ideas, let me know!WOOOOOW. In comparison, diet cokes showed reduced reaction times. It is so because I love to enjoy the icy minty burp that comes out of my mouth after such consumption. 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. A&W 1/3 Pound Burger Failure Fact Check: Are Americans Really That Bad at Fractions? I then quickly swallowed whole 3 mint mentos, using a small ammount of water to chase them down quickly. 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. Use the needle to thread the string through four Mentos, leaving a 10cm length of sting trailing off the Mentos Bundle. It is the classic Diet Coke and Mentos "geyser" experiment, but with the added rigor of using the scientific method to answer the question "Which will cause a larger reaction: the sugar in regular Coke or the aspartame in Diet Coke?" However, the only way to know what would happen would be to do an experiment. The reaction occurs between these little pores and the carbon dioxide dissolved in the solution. Therefore, diet soda is better than regular soda if you want to make the biggest Mentos foam geyser possible. 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. 124 lessons. Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. I'm addicted to Crystal Pepsi: https://youtu.be/qEjy3dS6COs \"HAVE A CRYSTAL PEPSI DAY!\" - L.A. Likewise, stories of children dying from a soda and Mentos compination appear to be nothing more than an update of the urban legend concerning Mikey, the childhood star of a series of Life cereal commercials who was a notoriously picky eater.
