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. Its not recommended to do this, even for a party trick, but youll survive with only your pride wounded overall. Therefore, diet soda is better than regular soda if you want to make the biggest Mentos foam geyser possible. 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. I will, but i have to wait until i can get hold of some. 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. When taken with fruit juice, creatine is more easily absorbed by the body. If youre still on the fence about trying it, it may help to know that the experiment also provides some basic insights on the chemical and physical properties of reactants so its an educational experiment, too! Open the soda and place the index card over the bottle opening. Mentos react with Diet Coke because their rough surfaces provide suitable sites for rapid growth of carbon dioxide bubbles, according to Mental Floss magazine. The Diet Coke and Mentos experiment results from an increased rate of nucleation. Thread the trailing string length through the bottle cap. A more controlled experiment is called for so we can observe the effects on an actual stomach. Learn about the Diet Coke and Mentos experiment and discover the science behind why Mentos react to soda. Diet Coke and Mentos - . You can always add more Mentos for a bigger effect. Further versions of the story specified the deceased youngster was the taciturn "Mikey" of LIFE cereal commercials. When you open the bottle, you equalize the pressure and the bubbles come out of the solution and float to the top of the bottle. 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. 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. And most reports of death involve someone eating Mentos rather than swallowing them, which would probably cause little to know reaction. 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. One drop at a time, drop each liquid onto its own penny. this big guy just dropped another BOOMIN video so like it up. 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. Low surface tension also helps bubbles grow quickly. 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 blog aims to bring you everything soda-related - so whether thats burning questions, tips, recipes, and even in-depth tutorials for making your own healthy soft drinks at home. This in turns means that the carbon dioxide gas is more rapidly released. The Mentos and Coke trick usually gets performed with diet cola. Version 1 - Mentos and Diet Coke vs. Mentos and other diet sodas. She is also certified in secondary special education, biology, and physics in Massachusetts. Even if it did, you'd just end up belching/vomiting it all out. 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. Cans Of Bernard Dehydrated Water: What in the World is This? Once you drop the Mentos into the coke, stand back as it's VERY explosive. When i inflate using pumps, Plavini and the like, i manage up to thirty litres equivalent at atmospheric pressure. 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. an experiment conducted by elizabeth snider for ede4304 october 9, 2006. diet coke and This site SodaPopCraft.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking toAmazon.com. What Does "All Day" Mean in Restaurant Slang. This is essentially speeding up the process that makes sodas fizzy. I've tried it, unsuccessfully. June 15, 2008 -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Last night's episode of Two and a Half Men just proves that one of the show's writers is a science geek with a sense of humor. 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. While we cant really know what kind of damage this kid may have done to his stomach, the results were fairly predictable. It turns out that Mentos have a very porous surface, with thousands of tiny indentations, perfect for nucleation. 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" ). The Diet Coke and Mentos experiment results from the nucleation of carbon dioxide from liquid to gas. Thus, the rates of nucleation are further increased. Was Coca-Cola the First Soda to Use Santa In Advertisements? First you need a 2 liter of diet coke and 2-3 packs of mentos. Here's an experiment to try at home regarding surface tension. Which brings us back to this article's topic, the ballyhooed death of a youngster who consumed this combination. 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. However, the Coke and Mentos experiment does not only involve a physical change. The gruesome appeal of the combusted tot story kept the legend in circulation long after it had been repeatedly debunked and dismissed. This was a total disaster! However, this stomach did swell up a lot which would probably result in vomiting, just as we saw in the YouTube video. 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. You should also follow any safety advice and precautions listed on the product label. It is also found in many foods, including meat and fish. Mentos that drift peacefully through the soda will have a weaker reaction in comparison. It turns out Mentos were the best seeders for the reaction. The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. I did this all in less than a minute. I've had a couple of thoughts about the swallowing problem. Snopes and the Snopes.com logo are registered service marks of Snopes.com. Course, it could be just the soda inflating me. Making Lots of Bubbles. Date Of Creation: 17 September 2021. The force exerted by the soda stream can be harnessed to do work. 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. 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. Coca-Cola is a carbonated beverage that is full of dissolved carbon dioxide. You can also increase the effect by adding extra ingredients to a given soda. copyright 2003-2023 Study.com. "If you drop a pack of Mentos into a bottle of Diet Coke, you get this huge fountain of spray and Diet Coke foam coming out," says Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina. 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. 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. When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. Their explanation is this process called nucleation. Then I immediately chugged another half liter or so of coke. The gas form of carbon dioxide bonds with the water molecules present in the cola. The nucleation process is also faster, leading to higher gas pressure. 2. All of these tricks help to improve the speed and drama of a Mentos eruption. Put the open end of your tube of Mentos on the card and place it directly over the opening of the soda bottle. Carbon dioxide is the force that pushes the liquid out of the bottle in a fraction of a second. Numerous video clips of "Mentos eruptions" exist on the Internet; one needn't search all that diligently to stumble across scads of them. You might think that there is some ingredient in a Mentos candy causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. if the chalk method works well, tell me please :). When soda is poured into a glass, most of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface tension. wowee zowee. In this case, ice melting into water is a physical reaction. Acids and bases are common classes of chemicals that react with each other and with water. If this were the case, eating Mentos and drinking soda may indeed be dangerous. But the bubbling youll feel on your insides isnt easy or gentle, so it shouldnt be performed regularly. What is the science behind Mentos and Coke eruptions? 460 Words2 Pages. No evidence was ever found that this story was true. As it does not have sugar so it will be easy to clean up the mess after experiment. With this in mind, the chemicals in Mentos also serve as foaming agents by facilitating the rapid release of CO2 gas. All content published on theReAgent.ieblog is for information only. 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. 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. Sodium bicarbonate can throw your acid-base balance way out and kill you. My next plan is to use powdered chalk and fizzy water. Overall, theres no need to worry if youve done this once or twice before on a dare from a friend. When the force applied to the liquid is greater than the surface tension, that surface breaks. 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). There once was a rumor that two children had died because they ate Mentos and drank Coca-Cola at the same time. The bubbles' buoyancy coupled with their rapid growth, causes them to rise to the surface, resulting in an eruption of foamy diet soda. What is the Difference Between Convection and Induction Cooking? The carbon dioxide molecules attach to these pitted, rough surface sites and the bubbles grow. First, the act of drinking soda releases quite a bit of the carbonation in it, limiting the possible effect. Thus, the process represented in Equation 1 - which powers the Coke and Mentos fountain - is a physical change. half a roll) in the test tube. Acids are often sour tasting. Additionally, we do not recommend using any chemical without reading theMaterial Safety Data Sheet (MSDS), which can be obtained from the manufacturer. Add Tip. What happened when you added the Mentos to the Diet Coke? 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. * 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. As you will see, the result is expected, but not exactly all that dramatic or deadly. 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. This rate is increased because the texture and density of mentos allow bubbles to form quickly, which in turn forms more bubbles. [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. (It's not just Diet Coke and Mentos that react; other carbonated Was Coca Cola the only Soft Drink to Contain Cocaine? 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. They are so small you cant even see them, but they number in the thousands, at least. First, you will need to prepare your crushed Mentos candies. The Hypothesis The scientific method is an important way scientists make observations and come to conclusions. Drop several Mentos into a bottle of coke or lemonade, and a huge eruption of bubbles shoots out several meters high. I dunno, I've chewed up a mentos and dropped it in soda- still fizz's just fine. Slowly and carefully open a new bottle of Diet Coke. It certainly wont be comfortable and Mentos, but there arent any real health risks from doing so. Theoretically speaking, any candy that has enough small pores like Mentos should be able to do this job. So, myth busted. much more than one liter could give me on its own. Diet Coke and Mentos - . It is a physical reaction rather than a chemical one. you got good ideas, let me know!WOOOOOW TELL ME WHAT TO POST NEXT!Youtube is F*cked they disabled comments! a popular reaction:. Since 2005 the Coke & Mentos reaction has been wow-ing children and adults everywhere - when it goes well! According to the Diet Coke and Mentos Eruption article, pop is supersaturated with gas. This year, I adapted my somewhat free-wheeling "wing it" approach to this experiment to instead have students research, test, and adapt as needed. Already have an account? 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. 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. Vomiting in excess is never a good sign since stomach acid wears away the cells of the esophagus and can cause mouth or throat cancer. 1. What will happen if we put Mentos in 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. This is a fun and exciting experiment designed for 3rd-6th graders. how can they do it then? But what causes this reaction? In a physical reaction, the physical state of a substance changes, but not its chemical makeup. * Just drinking fizzy water was fairly OK but made me cold to the extent of uncontrollable shivering. You may want an adult to help you crush the Mentos candies. It makes it a rather impractical exercise, i think. "This was a good project for my students to study because there was still some mystery to it.". As previously stated, the surface of Mentos candies is what makes this reaction work. Scooping up powder and cramming it into them for an hour sucks :/. However, the failure of this explosive combination of candy and soda to cause any fatalities should not be taken as a ringing endorsement of chasing down a handful of Mentos with as much pop as can be gulped. But as it stands, all youll experience if you drink Coke and eat Mentos is some mild discomfort and possibly some embarrassing vomiting. Almost everyone in middle school or high school has heard the urban legend: if you drink Coke and eat Mentos, youll explode! When soda is made, manufacturers oversaturate a liquid drink with gaseous carbon dioxide. Instead, the vigour of the jets depends on various factors that affect the growth rate of carbon dioxide bubbles. The Coke-Mentos experiment is one of the most popular science experiments and also one of the most well-known. 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. Imagine a huge geyser erupting at Yellowstone National Park. but i have seen videos of it on youtube? essentially cause a lot of the carbon dioxide trapped. 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. The bubbles are carbon dioxide, and when the soda is pressurized, it can hold more carbon dioxide. Whats up people. What is the most reasonable hypothesis to explain the difference? To find out more, Coffey and a team of students tested the reactions between Diet Coke and fruit Mentos, mint Mentos, and various ingredients such as other mints, dish-washing detergent, table salt and sand. Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres. However, i think it's a case of using a relatively inert powder with something carbonated. Then I immediately chugged another half liter or so of coke. Both fruit and mint Mentos will work for this experiment. Key Takeaways: Mentos and Coke Trick. . The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. 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 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 . 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. Do you think Mentos would react with all liquids or just some? This field is for validation purposes and should be left unchanged. Take the geyser tube and put all the mentos in it from the packet. Now that this YouTuber has done us all a favor and performed this experiment, you do not have to. Mentos are then added to the solution, and the observers can stand back and watch a geyser form. The original ingredients of Coca-Cola contained cocaine from coca leaves and caffeine-rich extracts from kola nuts. What chemical in Mentos makes soda explode? Pouring soda into a muddy hole in the ground does the same, so the Mentos are totally unnecessary. These chemicals are found in the shell itself as well as in the soda mixture, and they contribute to the formation of pressurised foam. In order for more carbon dioxide bubbles to be created, the bonds with the ambient water in the soda have to be broken. Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the Coke. The Diet Coke and Mentos experiments turn a sugar-free cola beverage and chewy candies into a geyser. First, choose an area that is okay to get messy. Create an account to start this course today. Also, stand clear of the bottle after you add the Mentos. also, i had to lay down to hold in the gas. 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 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). Enrolling in a course lets you earn progress by passing quizzes and exams. Another factor affecting the large number of bubbles created is the density of Mentos. Can find them at "vitamin" stores. The video is, of course, a joke and not real although many people claim it looks real. You can view this video on YouTube. 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. Find out more about our chemical manufacturing services, facilities, and accreditations. 124 lessons. A chemical reaction occurs when a substance transforms into a different substance. 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. 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). Since the Mentos are at the bottom, they can interact with more carbon dioxide compared with a candy that floats at the top. Do fruit Mentos work with Coke?
