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. Various types of carbonated beverages react differently with Mentos: Seltzer water has the weakest reaction while, very specifically, Diet Cherry Dr. Pepper has the strongest reaction. When soda is made, manufacturers oversaturate a liquid drink with gaseous carbon dioxide. You press it onto a heap of half-capsules of one side, press an identical one onto a heap of the other half of capsules, cover one layer in powder and place the other one precisely on top of it, capsules down. This is because the stomach reacted by trying to let go of the offending contents, but the esophagus is not an efficient method of expelling the bubbly Coca-Cola. Procedure: Stack the Mentos candies (approx. Their explanation is this process called nucleation. They covered this on Mythbusters. The gum is similar to the stuff in mentos, gum Arabic, which releases gas from fizzy drinks even if added alone. Carefully open the cap of the bottle of Coke. The carbon dioxide molecules are looking to attach themselves to any rough surface. Still not quite getting it? Then. Aside from the microscopic structures on the outside of the Mentos shells, there are several chemicals that make Coca-Cola explode in this way. I'm probably being pessimistic about it. Its like a teacher waved a magic wand and did the work for me. I might be expecting too much. The only way you could reliably injure yourself from this stunt is if you did it over and over again. Why does the reaction happen? how can they do it then? 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. For instance, if citric acid is added to a soda mixture, the fountain height will actually increase to up to six times its normal height. You can always add more Mentos for a bigger effect. Don't worry, legitimate scientists have actually studied this thing. The bubbles of nucleated gases that result from the surface of Mentos generate more bubbles to form. Thus, the process represented in Equation 1 - which powers the Coke and Mentos fountain - is a physical change. When combining Diet Coke and Mentos, one would get a physical reaction. This is the same thing that happens to any other container with volatile ingredients. Enrolling in a course lets you earn progress by passing quizzes and exams. Was Coca-Cola the First Soda to Use Santa In Advertisements? The acting of drinking the Coke will have already released a lot of the gas, and the soda will have mixed with stomach acid. Don't worry, legitimate scientists have actually studied this thing. This is essentially speeding up the process that makes sodas fizzy. Place a piece of wax paper on top of the cutting board. Try to keep as much of the co2 in the coke ie not shaking it. Thats why you feel bloated and your burp. you got good ideas, let me know!WOOOOOW TELL ME WHAT TO POST NEXT!Youtube is F*cked they disabled comments! The mint ones have small dents in them, which allows the coke to react immediately. If drops are continually added, this bubble will grow and continually burst, spilling water down the sides of the glass. Not all such videos found on the Web are on the up-and-up, however, including the famed "Pepsi Girl" clip, which purports to document a demise caused by the ingestion of a mixture of Mentos and Coca-Cola. A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. 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. Snopes and the Snopes.com logo are registered service marks of Snopes.com. When soda is poured into a glass, most of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface tension. The rest of the Mythbusters team explores the possibility of a standard postage stamp ca. For all the liquid to leave through the opening, the upstream pressure then also has to increase, redirecting the flow of the Coke upwards and you know the rest: explosion. Though the manuscript is behind a paywall, a presentation that Dr. Coffey made about the experience is available on the schools website. However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. The nucleation process is also faster, leading to higher gas pressure.

Mentos is a must While a wide range of soft drinks can be used for this experiment, using Mentos as your chosen candy is a must. Then I immediately chugged another half liter or so of coke. Aluminum Foil: Should the Shiny Side be Up or Down When Cooking? Is the How Coca-Cola Reacts to Stomach Acid Video Real? 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. "All enquiries are treated as confidential - we never share your details", "We provide comprehensive technical support with every enquiry", "Our manufacturing facility is accredited to ISO 9001, ISO 13485, ISO 14001 and ISO 45001", Explore Chemistry at the Catalyst Science Discovery Centre, Your Own Body Is Actually The Cause of Sunburn, This site is protected by reCAPTCHA and the Google. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Thread the trailing string length through the bottle cap. 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. With this in mind, the chemicals in Mentos also serve as foaming agents by facilitating the rapid release of CO2 gas. The "child who died from combining Mentos and Coca-Cola" story is an updating of an older legend that began in 1979. But what is the science behind this thrilling visual display? mentos eruption. You could use a dry mixture of two powders which generate carbon dioxide when they dissolve in water. 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. If you'd like to try more than one Mentos, roll them into a small paper tube to drop in. Mentos are then added to the solution, and the observers can stand back and watch a geyser form. 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. 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. The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. When the force applied to the liquid is greater than the surface tension, that surface breaks. Mentos that drift peacefully through the soda will have a weaker reaction in comparison. Mentos dont only react with Coca-Cola. The short answer is that eating Mentos by chewing them up while drinking Coca-Cola, or any other soda, will little to no effect. No evidence was ever found that this story was true. Forgot password? 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. but then after an hour i realised my tummy had gone down, so it had risen, i just hadnt noticed alot lol. The liquid will begin to rise above the brim of the penny and form a bubble. Video Instruction. While we cant really know what kind of damage this kid may have done to his stomach, the results were fairly predictable. 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. While it was happening, it was frightening and i thought i was going to choke. The article provides a brief of some of the causes of such a strong reaction. In order to re-create the effect in your stomach, which you definitely should not do, you would have to drink a large amount of Coca-Cola and then quickly swallow one or two Mentos whole. Copyright 2023 @ Sodoapopcraft.com Watson-Publishing Limited Co. Telephone: +441414590217 Email: [emailprotected]. The original ingredients of Coca-Cola contained cocaine from coca leaves and caffeine-rich extracts from kola nuts. Now, make a Mentos-and-soda fountain! Try a new bottle of Diet Coke and a new package of Mentos. When taken with fruit juice, creatine is more easily absorbed by the body. The last step is to stand back quickly and enjoy the spectacular reaction. Here's an experiment to try at home regarding surface tension. 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. If I was, I doubt I would even talk to you anyway. Imagine a glass that's being filled with water a single drop at a time. Additionally, SodaPopCraft.com participates in other affiliate programs, Clickbank, CJ, ShareAsale and other sites and we sometimes get a commission through purchases made through our links. Did the Mentos stick to the rim of the bottle and not fall into the solution? Surface tension is the bond between molecules in the liquid. It is almost certainly not true that anyone has ever died from doing this. Collect the following materials: Place the pennies on a flat surface. 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. 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. Already have an account? Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. This happens because the surface of Mentos has thousands of microscopic pores, peaks, pits and craters in it so what we see to be a smooth outer shell is pure deception. The Diet Coke and Mentos geyser is the result of a physical process rather than a chemical reaction. Search Pepsi Girl + Mentos. A study reveals why Mentos and Coke can be a dangerous combination. Mentos has thousands of tiny bumps over its surface even though the candy might look smooth to the naked eye. Drop your Mentos in the Diet Coke and step back - it's about to get messy! Thus, the rates of nucleation are further increased. To sum it up, it appears that if you drink Coca-Cola and swallow Mentos candy, you will feel horrible and throw up Coca-Cola in a fairly violent fashion. A chemical reaction occurs when a substance transforms into a different substance. Mentos Geyser Experiment. Its not only the surfaces of the Mentos that react with Coca-Cola. Diet soda does work a bit better than regular soda, but the main reason it gets used is because it doesn't leave a sticky residue on surfaces. In order for more carbon dioxide bubbles to be created, the bonds with the ambient water in the soda have to be broken. Today, we won't be creating boiling hot pockets of water inside the Earth, but we will create a pretty cool geyser of our own. Sign up to read all wikis and quizzes in math, science, and engineering topics. Here are some of the chemicals that make up the shell: These ingredients act as surfactants and help accelerate the release of carbon dioxide gas. So you won't get the same reaction in your stomach. It doesn't matter if the liquid contains sugar or not. The Hypothesis The scientific method is an important way scientists make observations and come to conclusions. Surface tension allows a cup to be filled with water past its brim. Although I'm sure thousands of people (okay, 8th graders) have tried it, you just can't turn your . Acids and bases are common classes of chemicals that react with each other and with water. Steaming hot water bursts into the air with the crowd watching in awe. Density is how much mass is in a given volume. (2008). This forces the liquid to overflow and shoot out. 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. This spectacle is mainly caused by a physical reaction that rapidly releases the dissolved carbon dioxide from the beverage. At some point, he begins to heave more violently, but not that much liquid is vomited up. Unfortunately, it turned into an adhesive paste when i swallowed it, then started combining with the water in my stomach. Diet Coke and Mentos - . Creatine can be taken as a supplement to help improve athletic performance and increase muscle mass. New user? when the gas builds up, your body will release it through belching. 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 surface of the Mentos provides nucleation sites for the CO2 to form bubbles. However, you may do untold damage to your stomach. Part of the scientific method is making a prediction called a hypothesis. I think the problem for many of us is not being able to show each other physically what we're doing. However InflatableSteve's Video that was grand lolz. 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. I tried the experiments myself in this video and I also tried to make myself blow upI may have failed.Furious Apparel http://www.furiouspete.comMy Camera Gear: http://bit.ly/WhatIShootWithSubscribe to Daily Vlogs! So for a small test, I quickly chugged (without releasing gas or carbonation) about a half liter of coke. The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. She is a current PhD student in biology at Wake Forest University, and has been teaching undergraduate students biology for the last three years. June 15, 2008 — -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres. 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. A Big ass explosion happenspretty damn cool. A yard or large patio (without furniture nearby) with a sturdy, flat surface will work great. At 0 degrees, the reaction time was 1.7 seconds and decreased to 0.6 seconds when the temperature increased to 80 degrees. A video that has been around since 2006 and has been seen at least 20 million times purports to show the death of a girl nicknamed Pepsi Girl (not to be confused with the curly-haired little girl on old Pepsi commercials) meet her death after downing a 2-liter bottle of Pepsi cola when she explodes as if a bomb has been placed inside her. No chemical reaction occurs either way, Mentos+Coke is a physical reaction. Almost everyone in middle school or high school has heard the urban legend: if you drink Coke and eat Mentos, youll explode! 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. Can find them at "vitamin" stores. NEW CHALLENGE and it turned put great. Put the open end of your tube of Mentos on the card and place it directly over the opening of the soda bottle. Answer (1 of 7): No. 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. Also, stand clear of the bottle after you add the Mentos. 1. This spectacle is mainly caused by a physical reaction that rapidly releases the dissolved carbon dioxide from the beverage. One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. The "child who died from combining Mentos and Coca-Cola" story is an updating of an older legend that began in 1979. (Can You Bring Cans On A Plane). Do you think Mentos would react with all liquids or just some? It causes me no vomiting as well as no. Key Takeaways: Mentos and Coke Trick.

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. Why do Mentos and Diet Coke react so strongly? The Diet Coke and Mentos experiments turn a sugar-free cola beverage and chewy candies into a geyser. 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. So, myth busted. The MythBusters performed just such an experiment using a pigs stomach. Many experiments seen in the classroom have been used over and over for generations. Sign up, Existing user? 460 Words2 Pages. The answer to this involves a property called surface tension. I think the cracks in the mentos will disappear during consumption. Common bases are found glass cleaners (ammonia), antacid tablets (carbonate), baking soda (also carbonate), and toothpaste (fluoride). do with the outside." You may want an adult to help you crush the Mentos candies. Sticking a finger into a glass of soda will result in the formation of tiny bubbles full of carbon dioxide that stick to the skin. Update Date: 3 January 2023. Theoretically speaking, any candy that has enough small pores like Mentos should be able to do this job. Not surprising from a fellow who doesnt think people actually buy Mentos casually. No Dude, they just make them for Coca-Cola experiments. The formation of carbon dioxide bubbles is like a chain reaction that exponentially accumulates, causing pressure to build in a fraction of a second. Mentos are denser than Diet Coke. However, the Coke and Mentos experiment does not only involve a physical change. 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. The narrow neck of the bottle also intensifies the pressure and speed because it forces the flow rate to increase. This pre-release of the gas prevents much of the dramatic release of the gas caused by the Mentos. Effects of diet coke and mentos on the body. 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. The other thing that happened was that the gas came straight back up and made me belch huge clouds of powder. Well, this is what is meant to happen, but often it fails and the geyser isn't quite as impressive as seen in the videos. How Long Do They Last? Stop messaging me thinking I'm a girl. 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. Next topic: Old 3 part inflation story. 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. All rights reserved. Then I immediately chugged another half liter or so of coke. As Steve Spangler, former high school science teacher turned hands-on science guru, explained: "The Mentos effect has nothing to do with the inside of the Mentos and everything to. 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. Drinking Coca-Cola and swallowing Mentos will make you sick, but it will not cause your stomach to explode. When this happens fast enough, you get a nice Diet Coke fountain. Mentos candies are not as smooth as they appear to the naked eye. She is also certified in secondary special education, biology, and physics in Massachusetts. 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. Put it on the bottle in such a way that all the mentos in the tube are . When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. -which do I consume first? coke geyser. Then eat . 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. All content 2019 by Eric Troy and CulinaryLore. This is the same thing that happens to any other container with volatile ingredients. Pour out the first 5cm of Diet Coke for extra working room. 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. What Is The Chemical Structure Of Coca-Cola? The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. I will, but i have to wait until i can get hold of some. What will happen if we put Mentos in Coke? 13 chapters | 0:00 / 5:15 Diet Coke and Mentos Human Experiment **DON'T TRY THIS AT HOME** | Furious Pete Furious Pete 5.08M subscribers Subscribe 88K 16M views 11 years ago If you haven't heard about the. Procedure: -. also, i had to lay down to hold in the gas. 2. I hope it inspires you to make your own healthier fizzy drinks at home. 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. First you need a 2 liter of diet coke and 2-3 packs of mentos. The Mentos and Coke trick usually gets performed with diet cola. For instance, in photosynthesis, water and carbon dioxide are transformed into sugar. As previously stated, the surface of Mentos candies is what makes this reaction work. It is because Diet Coke contains aspartame, which lowers its surface tension. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. If too much of the fizz escapes before you add the mento the reaction . Mixing mentos and soda makes a great science demonstration for students studying gases, thermodynamics, fluid dynamics, surface science, and the physics of explosions among other chemistry and physics concepts. Mentos candies typically have gum Arabic and gelatin in their formulas. "It's a great way to get students excited about science and learn something new. The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres. 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. A rougher candy surface translates to more places for bubbles to grow, or more nucleation sites. Step 3: Shake and Launch! Buy chewing up the candy you have destroyed all the little pores that result in the large surface area responsible for the nucleation reaction. Once you drop the Mentos into the coke, stand back as it's VERY explosive. But i think nucleation sites are the way to go, not an actual chemical reaction. Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the Coke. Ok, so I was curious about this as well. He obviously feels terrible and has a bad stomachache. 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. Pouring soda into a muddy hole in the ground does the same, so the Mentos are totally unnecessary. I dunno, I've chewed up a mentos and dropped it in soda- still fizz's just fine. Please contact for permissions. They also compared reactions using other fizzy liquids such as caffeine-free and sugary colas, as well as soda water and tonic water.
