1. Low surface tension also helps bubbles grow quickly. Whats up people. Inflation from diet coke and mentos can cause an increase in blood pressure, heart rate, and body Plus, some folks swear diet sodas make for higher geysers. Log in here. This is the same thing that happens to any other container with volatile ingredients. Open the pack of Mentos and place all of them in the tube. The YouTube video discussed above is not exactly scientific, however. Of course, this is for YouTube, so he continues drinking and swallowing candy. I've tried it, unsuccessfully. Why is Diet Coke a better choice for this experiment than other sodas? Mint candies are more basic, increasing the acid-base reaction, Mint candies are more acidic, increasing the acid-base reaction, Fruit candies have a more rough coating, decreasing nucleation sites, Fruit candies have a smoother coating, decreasing nucleation sites, http://www.appstate.edu/~coffeyts/DietCokeandMentos.pdf, https://www.youtube.com/watch?v=mb6neBVtvsE, https://brilliant.org/wiki/why-do-mentos-explode-in-coke/. Why does Mentos react to soda? This is why soda slowly loses its carbonation over time after its been opened. I dunno, I've chewed up a mentos and dropped it in soda- still fizz's just fine. All the carbon dioxide in the soda - all that fizz - is squeezed into the liquid and looking for a way out. Next, secure a bottle of diet cola to the ground and remove the lid. Here's an experiment to try at home regarding surface tension. - Structure, Composition & Facts, The Total of All Chemical Reactions in an Organism, Working Scholars Bringing Tuition-Free College to the Community. Mentos will result in the formation of a geyser in any carbonated liquid. Essentially, surface tension is the ability of a liquid to stick together due to its molecular properties. Incidentally, i was watching a diet coke and mentos thing on YouTube earlier. Then. As a result, they are important biologically, industrially, and environmentally. Because these molecules are thus less likely to hold onto each other, the solution is easier to disrupt. When soda is poured into a glass, most of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface tension. Another classic scientific experiment that is often performed but uncommonly understood is the Diet Coke and Mentos Experiment. do with the outside." The formation of carbon dioxide bubbles is like a chain reaction that exponentially accumulates, causing pressure to build in a fraction of a second. I was snorting gum out of it for hours afterwards. Add Tip. Most Coca-Cola is kept carbonated by a sealed bottle, which creates a pressurized environment where the carbonated gas cant escape until the cap has been broken off or opened. I used the cheapest brands available in our local supermarket. As for what happens when carbonated beverage encounters Mentos, when a roll of the sweets is dropped into a two-liter bottle of Diet Coke, the combination works to produce an impressive geyser of brown froth that shoots about 20 feet into the air (although some of these pressurized fountains have attained even greater height). I think the cracks in the mentos will disappear during consumption. Next topic: Old 3 part inflation story. copyright 2003-2023 Study.com. this big guy just dropped another BOOMIN video so like it up. Additionally, diet sodas produce bigger reactions than regular sodas, because diet sodas such as Diet Coke contain potassium benzoate and the artificial sweetener, aspartame, as opposed to sugar or corn syrup. In an . Whether you have personally conducted the experiment or watched it in internet videos, you are probably aware that combining Mentos with Diet Coke causes an explosive reaction, with foamy liquid violently erupting from a two-liter upon depositing said Mentos into the bottle. Imagine a glass that's being filled with water a single drop at a time. Diet Coke, a sugar-free cola beverage, and Mentos, a chewy round candy, are combined to generate a Diet Coke and Mentos eruption. This is likely for two reasons. Find out more about our chemical manufacturing services, facilities, and accreditations. 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 mints are small oblate spheroids, with a slightly hard exterior and a soft, chewy interior.. It certainly wont be comfortable and Mentos, but there arent any real health risks from doing so. Does Diet Soda Make a Difference With Mentos? Im the owner and blogger here at SodaPopCraft.Com. The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. The resulting effect is quick, high, and explosive, yet what takes place is not a chemical reaction but a physical one (even though some are moved to believe the confection's gum arabic component or diet soda's aspartame has something to do with the process). The trick is to drop the mento in as fast as you can. Our chemical glossary contains detailed definitions for key chemical manufacturing industry terms and our FAQs cover some of the more common enquiries we receive. Materials: 1 pkg. It could easily have got quite serious, i think. Many people speculated that the geyser was the result of an acid base reaction, given the low pH of soda. Only after the Mythbusters pumped a large amount of compressed air into the stomach did it finally burst, and it took a LOT of air. But there have been no rigorous scientific studies of the reaction until now. 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. Mentos has thousands of tiny bumps over its surface even though the candy might look smooth to the naked eye. 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. A lot of people, myself included, believe the diet coke + Mentos reaction is the same as the baking soda + vinegar "volcano" reactions that we all did as kids. Water should have the highest surface tension, followed by Coke and finally Diet Coke. There is an urban legend that eating mentos while drinking soda could cause a person's stomach to burst. The reaction occurs between these little pores and the carbon dioxide dissolved in the solution. Why do Mentos and Diet Coke react so strongly? 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. All content 2019 by Eric Troy and CulinaryLore. When Diet Coke and Mentos join, the result should be a large fountain of foamy soda that erupts from the bottle. So, when a Mento is dropped into some Coke, the acidity of the soda mixture quickly dissolves its shell, releasing the chemicals. Create an account to start this course today. Instructions. Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. in action:. Mentos Geyser Experiment. The eruption you get when you mix Mentos and Coke is generated by the rough coating of the candy, which causes lots of bubbles to form rapidly on its surface when it's placed in a carbonated beverage. They are so small you cant even see them, but they number in the thousands, at least. Mentos mints are covered with many very tiny pores or nucleation sites. So what happens if you drink coke and eat Mentos? Watch the full video for a more detailed explanation. If drops are continually added, this bubble will grow and continually burst, spilling water down the sides of the glass. coke geyser. And while Snopes long ago debunked the rumor that eating Mentos and drinking Diet Coke can kill you, exercising caution when attempting to mix these two products together is recommended. Anything that breaks them apart allows for bubbles of carbon dioxide gas to form in the solution. It is also found in many foods, including meat and fish. You can't swallow them whole and the saliva is going to soften and dissolve the irregularities. also, i had to lay down to hold in the gas. This is because fruity Mentos have an extra coating of flavor which slows down the reaction time. Surfactants lower the surface tension between two liquids, a liquid and a solid, or between a gas and a liquid. [RAMUNE SODA FLAVORS], Will Soda Cans Explode in Checked Baggage? Course, it could be just the soda inflating me. Mint Mentos candies 2-liter Diet Coke 2-liter Diet 7-Up 2-liter Dr. Thunder 1-liter measuring beaker Procedure: Unscrew the cap of the first 2-liter bottle of soda . Already have an account? So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. Speed also matters, and the faster the Mentos sinks, the larger the eruption. We dropped two Mentos into a bottle of normal Cola and Diet Cola. 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. Can find them at "vitamin" stores. 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. But the bubbling youll feel on your insides isnt easy or gentle, so it shouldnt be performed regularly. Hold Bottle by top with one hand place around the neck so that the bottle is upside down. 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. This material may not be reproduced without permission. Date Of Creation: 17 September 2021. [1], Tonya Coffey, a professor at Appalachian State University, used the experiment to give her undergraduate physics class a real-world research experience as one of their laboratory assignments. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. I'll try more next time. 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. diet soda eschews these ingredients in the name of fewer calories, dishwasher soap and water to a soda bottle. Do you think Mentos would react with all liquids or just some? As it does not have sugar so it will be easy to clean up the mess after experiment. They are a pain in the ass to make, though. 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. Sign up, Existing user? But, it is true that a violent reaction occurs when you put Mentos into a bottle of Coke. 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. I will, but i have to wait until i can get hold of some. The Diet Coke and Mentos experiments turn a sugar-free cola beverage and chewy candies into a geyser. Place the soda bottle outside in and area that can get dirty. Soda slowly loses its carbonation over time after its been opened that is performed.
