Use the needle to thread the string through four Mentos, leaving a 10cm length of sting trailing off the Mentos Bundle. This forces the liquid to overflow and shoot out. On the wax paper, carefully use the knife to crush and cut four Mentos candies into many small pieces, as shown in Figure 2 below. So why do Mentos make so many bubbles? The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. The Mentos experiment can be done with any soda or carbonated liquid. Finally, making your soda bottle warmer instead of colder will make the geyser higher and faster. It could easily have got quite serious, i think. 1. This way, you can see which one erupts higher. So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. The trick is to drop the mento in as fast as you can. Next topic: Old 3 part inflation story. 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. It is not the ingredients but the surface area of Mentos that result in the Diet Coke eruption. Mentos are dense candies, which aids the sinking process a factor the study explored by comparing reactions made with whole Mentos versus crushed ones, the latter of which resulted in weaker eruptions. In order to understand why Coke and Mentos react so explosively, you have to understand how both ingredients work in the first place. The reaction between Diet Coke and mentos is caused by nucleation. To conduct this experiment, first start off by finding a location that can be easily cleaned or hosed off, such as an open area outside. Gotta do it fast, though. At 0 degrees, the reaction time was 1.7 seconds and decreased to 0.6 seconds when the temperature increased to 80 degrees. When this happens fast enough, you get a nice Diet Coke fountain. It's every 8th grader's dream either you spew a volcano of soda or you explode. Hypothesis: If three Mentos are dropped into a 2-liter of Diet Coke, Diet 7-Up, and Dr Thunder, then the Diet Coke will have the largest reaction to the Mentos. anyways no expanding tummy as of yet. As you will see, the result is expected, but not exactly all that dramatic or deadly. Ok, so I was curious about this as well. Mentos will result in the formation of a geyser in any carbonated liquid. 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. If your eruption wasn't everything you'd hoped for, make sure you have fresh ingredients. Creatine can be taken as a supplement to help improve athletic performance and increase muscle mass. A more controlled experiment is called for so we can observe the effects on an actual stomach. Imagine this small process happening thousands of times in the second and you get the trademark fountain of soda bubbles that rise out of the bottle. 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. What is the science behind Mentos and Coke eruptions? 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?" Anything can cause nucleation, like a lemon or a jelly bean. Effects of diet coke and mentos on the body. When combining Diet Coke and Mentos, one would get a physical reaction. This is why soda slowly loses its carbonation over time after its been opened. "And if you have rough candy with a high ratio of surface area to volume, then there's more places for the bubbles to go.". Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle. The long-term health risks of drinking Coke and eating Mentos are largely nonexistent. All Rights Reserved. The formation of carbon dioxide bubbles is like a chain reaction that exponentially accumulates, causing pressure to build in a fraction of a second. In an . haha at first i was like wtf man? I then quickly swallowed whole 3 mint mentos, using a small ammount of water to chase them down quickly. Safety Tip!! But, any carbonated beverage works. Thus, the texture of Mentos alone increases the rate of nucleation. As a result, they are important biologically, industrially, and environmentally. Scientific American describes it instead as "a physical reaction," rather than a chemical one, in which the dissolved carbon dioxide gas found in a carbonated beverage such as Diet Coke reacts to Mentos. Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. She is also certified in secondary special education, biology, and physics in Massachusetts. Cover the opening of the test tube with an index card or similar slim, small paper. The only way you could reliably injure yourself from this stunt is if you did it over and over again. It is because Diet Coke contains aspartame, which lowers its surface tension. In comparison, diet cokes showed reduced reaction times. Its like a teacher waved a magic wand and did the work for me. Next, secure a bottle of diet cola to the ground and remove the lid. Water molecules are polar and attracted to each other. The bubbles are carbon dioxide, and when the soda is pressurized, it can hold more carbon dioxide. Add Tip. I was snorting gum out of it for hours afterwards. I'm a guy. If i'm using an acid too, for example tartaric or citric, the toxicity of bicarb, the acid and the compound resulting from the reaction are all important, as is the pH change of the internal environment. 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). The YouTube video discussed above is not exactly scientific, however. Date Of Creation: 17 September 2021. 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. The Diet Coke and Mentos geyser is the result of a physical process rather than a chemical reaction. Bottled sodas are kept under pressure so that more carbon dioxide can be forced into solution. Sodium bicarbonate can throw your acid-base balance way out and kill you. Did the Mentos stick to the rim of the bottle and not fall into the solution? This alert about an unnamed child in Brazil's sorry fate began circulating on the Internet in November 2006. I vaguely remember that episode. No evidence was ever found that this story was true. Inflation from diet coke and mentos can cause an increase in blood pressure, heart rate, and body * Citric acid and bicarbonate of soda should release lots of carbon dioxide. This year, I adapted my somewhat free-wheeling "wing it" approach to this experiment to instead have students research, test, and adapt as needed. Aluminum Foil: Should the Shiny Side be Up or Down When Cooking? Imagine a huge geyser erupting at Yellowstone National Park. The sudden swell of carbon dioxide inside your stomach will need an escape. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. Diet Coke, a sugar-free cola beverage, and Mentos, a chewy round candy, are combined to generate a Diet Coke and Mentos eruption. Additionally, the stomach has a couple ways of expelling excess gases. but i have seen videos of it on youtube? -does pepsi max work as a substitute for diet coke? "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.". It is also found in many foods, including meat and fish. 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. Therefore, diet soda is better than regular soda if you want to make the biggest Mentos foam geyser possible. Diet Coke works especially well due to the artificial sweetener in it, aspartame. how can they do it then? Protected by fear, few kids actually end up attempting the stunt, even to prove their guts to their peers. Search Pepsi Girl + Mentos. 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. Now, make a Mentos-and-soda fountain! 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. Then drink a little over half slowly in give or take 2 min. 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. Thread the trailing string length through the bottle cap. This keeps the bubble growth going. 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). Steaming hot water bursts into the air with the crowd watching in awe. However InflatableSteve's Video that was grand lolz. First, you will need to prepare your crushed Mentos candies. You should also follow any safety advice and precautions listed on the product label. Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the Coke. All the reactions took place in a bottle angled at 10 off vertical and the fountain trajectories were recorded on video. 124 lessons. The result is a massive eruption of foam, shooting stories high into the air. Concerning getting powder into capsules, you can get or make something for this. Surface tension allows a cup to be filled with water past its brim. Christina graduated with a Master's in biology from the University of Louisiana at Lafayette. You could even theoretically accomplish this with club soda, although the surface tension of the water wouldnt be weakened since club soda only has a few basic ingredients. [RAMUNE SODA FLAVORS], Will Soda Cans Explode in Checked Baggage? Also, stand clear of the bottle after you add the Mentos. Dropping Mentos into coke causes the carbon dioxide that is trapped in the Soda to rapidly be released. Coca-Cola is a carbonated beverage that is full of dissolved carbon dioxide. We can see how much better Diet Coke and Coke Zero react with Mentos just by looking at the experiment we showed earlier: both of these sugar-free sodas produced fountains that exceeded 2.5 metres, while the fountain produced by regular Coke barely reached 1.5 metres. Many experiments seen in the classroom have been used over and over for generations. One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. These microscopic irregularities on the Mentos surface serve as nucleation sites where carbon dioxide bubbles form. It was funny afterwards. But i think nucleation sites are the way to go, not an actual chemical reaction. Try a new bottle of Diet Coke and a new package of Mentos. The nucleation process is also faster, leading to higher gas pressure. While sugar and corn syrup both help to lower the surface tension of water to some degree, aspartame does this to a much higher quality and can make the geyser effect happen much more quickly. Version 1 - Mentos and Diet Coke vs. Mentos and other diet sodas. 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. 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. 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 . Do fruit Mentos work with Coke? It is likely that these stories are exaggerated and have been spread on the Internet for entertainment purposes. As the bubbles get bigger, they detach from the Mentos and race to the top of the soda. Try to keep as much of the co2 in the coke ie not shaking it. 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. The blog, its authors, and affiliates cannot be held responsible for any accident, injury or damage caused in part or directly from using the information provided. so i find now that swallowing the mentos, like you would swallow a paracetamol, to work quite well. I don't burp much, so I hold it in anyway. The original ingredients of Coca-Cola contained cocaine from coca leaves and caffeine-rich extracts from kola nuts. Both of these ingredients lower the surface tension of the soda, which exacerbates the bubbling reaction and makes the geyser happen much more quickly. 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. !Facebook http://www.facebook.com/furiouspeteInstagram http://www.instagram.com/furiouspete Furious Formulations: http://www.furiouscuts.comCheck out my other Channels:Vlogs http://www.youtube.com/furioustalksSupplement Reviews http://www.youtube.com/suppsreviewsThe Furious Dog http://www.youtube.com/thefuriousdogFurious Eats http://www.youtube.com/furiouspeteFurious GamePlay http://www.youtube.com/FuriousGamePlaySend cool stuff to my PO Box!Furious Pete1801 Lakeshore Rd W Unit 6PO Box 52559 Turtle CreekMississauga, ON, L5J 4S6Thanks for subscribing! Put it on the bottle in such a way that all the mentos in the tube are . Procedure: Stack the Mentos candies (approx. (Can You Bring Cans On A Plane). Key Takeaways: Mentos and Coke Trick. 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 MythBusters performed just such an experiment using a pigs stomach. "This was a good project for my students to study because there was still some mystery to it.". Place the soda bottle outside in and area that can get dirty. Mentos reacts strongly to all carbonated drinks owing to some of its molecular properties. 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. It turns out Mentos were the best seeders for the reaction. 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. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Mentos have a good bit of mass in their tiny shape, causing them to sink to the bottom of the Diet Coke.
