Plus, some folks swear diet sodas make for higher geysers. The other thing that happened was that the gas came straight back up and made me belch huge clouds of powder. [RAMUNE SODA FLAVORS], Will Soda Cans Explode in Checked Baggage? Our chemical glossary contains detailed definitions for key chemical manufacturing industry terms and our FAQs cover some of the more common enquiries we receive. The Diet Coke and Mentos reaction is a common experiment performed in many science classes. Why Does Japanese Soda Have a Marble? 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. Not surprising from a fellow who doesnt think people actually buy Mentos casually. No Dude, they just make them for Coca-Cola experiments. - Structure, Composition & Facts, The Total of All Chemical Reactions in an Organism, Working Scholars Bringing Tuition-Free College to the Community. With this in mind, the chemicals in Mentos also serve as foaming agents by facilitating the rapid release of CO2 gas. 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. Acids are often sour tasting. I think the cracks in the mentos will disappear during consumption. Nucleation is the process by which a state of matter becomes another state of matter on its own. What makes Cola and Mentos react? 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. also, i had to lay down to hold in the gas. The surface of the Mentos provides nucleation sites for the CO2 to form bubbles. Step 3: Shake and Launch! -does pepsi max work as a substitute for diet coke? Mentos candies typically have gum Arabic and gelatin in their formulas. That year, the grist being run through the rumor mill included the sad tale of a misadventuring tot who had gulped soda and ingested Pop Rocks, a carbonated candy known for producing a fizzling sensation in the mouth. Example: [Collected on the Internet, 2006]. * 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. There's a plastic layer with holes in. For instance, most students are familiar with baking soda and vinegar volcanos, have dabbled in watering plants with different types of liquid, and have attempted to make a battery out of a potato. So you won't get the same reaction in your stomach. Thread the trailing string length through the bottle cap. The YouTube video discussed above is not exactly scientific, however. Now that this YouTuber has done us all a favor and performed this experiment, you do not have to. Any type of soda is pressurized to keep it fizzy inside the bottle. What is the most reasonable hypothesis to explain the difference? June 15, 2008 -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Pop a bottle and have a browse. However, there are very few candies with the same kind of porous surface as Mentos, which is why the science experiment is typically done with these candies instead of others. Make sure you do it outside. Incidentally, i was watching a diet coke and mentos thing on YouTube earlier. Almost everyone in middle school or high school has heard the urban legend: if you drink Coke and eat Mentos, youll explode! 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/. A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage. Imagine a glass that's being filled with water a single drop at a time. When analyzing my new approach to this time . Overall, theres no need to worry if youve done this once or twice before on a dare from a friend. 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. Buy chewing up the candy you have destroyed all the little pores that result in the large surface area responsible for the nucleation reaction. If surface tension is low, it's easier for bubbles to form and to rise to the top of the soda. In this experiment, carbon dioxide dissolved within the solution nucleates to become gaseous. Then drink a little over half slowly in give or take 2 min. Apparently, we were dead wrong, as the paper points out: The pH of the diet Coke prior to the reaction was 3.0, and the pH of the diet Coke after the mint Mentos reaction was also 3.0. The force exerted by the soda stream can be harnessed to do work. 13 chapters | much more than one liter could give me on its own. The gruesome appeal of the combusted tot story kept the legend in circulation long after it had been repeatedly debunked and dismissed. Use the needle to thread the string through four Mentos, leaving a 10cm length of sting trailing off the Mentos Bundle. I don't burp much, so I hold it in anyway. Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the 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. Because these molecules are thus less likely to hold onto each other, the solution is easier to disrupt. All other trademarks and copyrights are the property of their respective owners. Create an account to start this course today. The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. Part of the scientific method is making a prediction called a hypothesis. Log in here. 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. Just it's structure. 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. All the carbon dioxide in the soda - all that fizz - is squeezed into the liquid and looking for a way out. It's been called the "vinegar and baking soda" reaction for a new generation. All content 2019 by Eric Troy and CulinaryLore. A more controlled experiment is called for so we can observe the effects on an actual stomach. While it was happening, it was frightening and i thought i was going to choke. Diet Coke and Mentos - . Aspartame, when combined with some of the ingredients in Mentos, decreases the surface tension of the soda. The bubbles are carbon dioxide, and when the soda is pressurized, it can hold more carbon dioxide. They are a pain in the ass to make, though. He was claimed to have died after eating Pop Rocks candy with soda. Do not try such experiments yourself though. Drop your Mentos in the Diet Coke and step back - it's about to get messy! Surfactants lower the surface tension between two liquids, a liquid and a solid, or between a gas and a liquid. The resulting splash from diet soda with this mixture would surely be something to record. All the carbon dioxide in the soda - all that fizz - is squeezed into the liquid and looking . A study reveals why Mentos and Coke can be a dangerous combination. 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). These experiments are classic because they are excellent examples of basic scientific properties, which can be learned in a fun and interactive way. 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. You can expect a large eruption. For instance, in photosynthesis, water and carbon dioxide are transformed into sugar. My next plan is to use powdered chalk and fizzy water. It worked, but even quite small quantities seem to start messing up my internal environment and i got cramps and tingling. Numerous video clips of "Mentos eruptions" exist on the Internet; one needn't search all that diligently to stumble across scads of them. Slowly and carefully open a new bottle of Diet Coke. Here's What Really Causes Diet Coke And Mentos To React. 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. When you drop a Mentos into the soda, tiny bumps on the candy surface give the carbon dioxide molecules a nucleation site or place to stick. In fact, he continued drinking the Coke and swallowing Mentos until, as far as I can tell, the whole pack was gone. 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. I've always had to explore this entire fetish on my own, that is, without anyone physically present i can share it with, and that probably makes me dogmatic and inflexible. Thousands of microscopic carbon dioxide bubbles accumulate in these pockets, which then leaves gaps inside the bottle. The rest of the process happens thanks to the physical properties of Mentos. If you down a large amount of soda, the carbon dioxide is released. The Diet Coke and Mentos experiment results from an increased rate of nucleation. Materials: 1 pkg. It turns out Mentos were the best seeders for the reaction. (2008). One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. 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. Their surfactant properties then lower the surface tension of the Coke, which breaks apart the water molecules and, in doing so, allows carbon dioxide bubbles to form more readily. 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. I vaguely remember that episode. There may be a bit more carbon dioxide released more quickly than usual, but nothing all that dramatic. 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. Another trick I do is stuffing baking powder into large 1 gram empty medicine capsules. Once you drop the Mentos into the coke, stand back as it's VERY explosive. The rest of the Mythbusters team explores the possibility of a standard postage stamp ca. 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. This alert about an unnamed child in Brazil's sorry fate began circulating on the Internet in November 2006. What Does "All Day" Mean in Restaurant Slang. anyways no expanding tummy as of yet. 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. Beware of the 20-foot stream of soda that will erupt when you pull off this experiment. 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. 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. Carefully open the cap of the bottle of Coke. Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres. 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. when you drink Soda, the contents of the stomach (stomach acid, food, etc.) 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. The chemical reactions involved in dropping mentos candies into a bottle of diet coke make quite the spectacle! Mentos dont only react with Coca-Cola. If you shake the can first, you disrupt the solution and get a face full of soda. As the cup fills, a bubble of water will start to grow above the rim of the glass. also, i had to lay down to hold in the gas. She is a current PhD student in biology at Wake Forest University, and has been teaching undergraduate students biology for the last three years. They covered this on Mythbusters. He obviously feels terrible and has a bad stomachache. This in turns means that the carbon dioxide gas is more rapidly released. ", As it sinks, the Mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a Diet Coke geyser. you got good ideas, let me know!WOOOOOW TELL ME WHAT TO POST NEXT!Youtube is F*cked they disabled comments! When Diet Coke and Mentos join, the result should be a large fountain of foamy soda that erupts from the bottle. This is likely for two reasons. Aside from the microscopic structures on the outside of the Mentos shells, there are several chemicals that make Coca-Cola explode in this way. There is no danger in eating Mentos mints while drinking Coca-Cola. 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. 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. This sound is a result of nucleation. but i have seen videos of it on youtube? As previously stated, the surface of Mentos candies is what makes this reaction work. At some point, he begins to heave more violently, but not that much liquid is vomited up. The combination of any carbonated liquid and mint-flavored Mentos will rapidly produce copious amounts of foam because the candy works to disrupt the surface tension of the liquid, thereby releasing all the drink's fizz (carbon dioxide) in one surprisingly speedy whoosh. A classic experiment in chemistry is combining a small candy called Mentos with Diet Coke. But the process is constant and grows exponentially. Do you think Mentos would react with all liquids or just some? First you need a 2 liter of diet coke and 2-3 packs of mentos. Try to keep as much of the co2 in the coke ie not shaking it. A two-litre bottle has about 15 grams of dissolved carbon dioxide, which, under the right conditions, becomes 8 litres of carbon dioxide gas in just a few seconds. 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. 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. But the bubbling youll feel on your insides isnt easy or gentle, so it shouldnt be performed regularly. What could you do to make your eruption bigger? 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. Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. Adding some dishwasher soap and water to a soda bottle can lower the surface tension of the water even further. But, any carbonated beverage works. 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 might be expecting too much. At 0 degrees, the reaction time was 1.7 seconds and decreased to 0.6 seconds when the temperature increased to 80 degrees. Chalk doesn't dissolve in water, so it should provide nucleation sites without getting soggy. According to the Diet Coke and Mentos Eruption article, pop is supersaturated with gas. Your stomach will not explode. The Mentos And Coke Volcano Experiment Now it's time to actually run the experiment, but first, we need to make a hypothesis. 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. if the chalk method works well, tell me please :). 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. Bases are bitter and feel slippery to the touch. While there are many stories of people dying from suddenly exploding due to the rush of carbon dioxide expanding in their stomach, none of these stories are factually true and no video footage has ever been recorded of such an accident. That way you can do maybe a hundred at once. If you have health and safety related questions, visitHSE.gov.uk. These microscopic irregularities on the Mentos' surface serve as nucleation sites where carbon dioxide bubbles form. Once again there hadn't been such a child, but that did little to slow the rumor's spread. Open the soda and place the index card over the bottle opening. As it does not have sugar so it will be easy to clean up the mess after experiment. What Chemical In Mentos Makes Coca-Cola Explode? Further versions of the story specified the deceased youngster was the taciturn "Mikey" of LIFE cereal commercials. What they found was what I suspected, that the actual act of drinking the soda released much of the carbon dioxide. The Diet Coke and Mentos experiment results from the nucleation of carbon dioxide from liquid to gas. Finally, making your soda bottle warmer instead of colder will make the geyser higher and faster. They, too, concluded that the "surface roughness" of the Mentos is "one of the main causes of the reaction. 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. Regular soda uses sugar or corn syrup to derive most of its sweetening flavor, but diet soda eschews these ingredients in the name of fewer calories and better health. I'm a guy. The surface tension of the water allowed it to fill above the rim of the glass. much more than one liter could give me on its own. 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! 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. It turns out that Mentos have a very porous surface, with thousands of tiny indentations, perfect for nucleation. It makes it a rather impractical exercise, i think. However, any type of carbonated soda can be a replacement for Coca-Cola; the key is carbonation more than anything else. All content published on theReAgent.ieblog is for information only. When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. Christina graduated with a Master's in biology from the University of Louisiana at Lafayette. Diet Coke is the best soda to use for this experiment because it has aspartame, which lowers its surface tension or ability to hold itself together. Since 2005 the Coke & Mentos reaction has been wow-ing children and adults everywhere - when it goes well! Don't worry, legitimate scientists have actually studied this thing. The answer to this involves a property called surface tension. These microscopic irregularities on the Mentos surface serve as nucleation sites where carbon dioxide bubbles form. Procedure: -. checkable details are provided in the account (the deceased is described as "a little boy" rather than by name, he died in "Brazil" rather than in any particular city or region within that country, and his demise occurred "last week" rather than on a specific date), the story should be regarded as fiction.

I'm addicted to Crystal Pepsi: https://youtu.be/qEjy3dS6COs \"HAVE A CRYSTAL PEPSI DAY!\" - L.A. No chemical reaction occurs either way, Mentos+Coke is a physical reaction. * Just drinking fizzy water was fairly OK but made me cold to the extent of uncontrollable shivering. * Citric acid and bicarbonate of soda should release lots of carbon dioxide. Water molecules are polar and attracted to each other. I pack, and 1-2 cans mountain dew. Answer (1 of 7): No. 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. Instead it is a physical reaction. Then. One enterprising group made a mentos and diet coke-powered rocket. 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. 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. 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. Their explanation is this process called nucleation. The mint Mentos mixed with diet coke usually explodes the longer and higher while fruit Mentos has a more delayed and less impressive reaction. The carbon dioxide molecules are looking to attach themselves to any rough surface. 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. I only managed about 2 litres of gas like this. coke geyser. 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! 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. The Coke-Mentos science experiment is certainly fun to do but its also messy, so we recommend doing it outside or in an easily-cleaned space, like a bath! Their explanation is this process called nucleation. In an . (Can You Bring Cans On A Plane). I hope it inspires you to make your own healthier fizzy drinks at home. Ok, so I was curious about this as well. Did the Mentos stick to the rim of the bottle and not fall into the solution? I was snorting gum out of it for hours afterwards. The bubbles' buoyancy coupled with their rapid growth, causes them to rise to the surface, resulting in an eruption of foamy diet soda. Collect the following materials: Place the pennies on a flat surface. 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. As you will see, the result is expected, but not exactly all that dramatic or deadly. 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 mint ones have small dents in them, which allows the coke to react immediately. When taken with fruit juice, creatine is more easily absorbed by the body. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. It works fine, the coke fizzes because of the cracks in the mentos, not the chemical makeup. Now, make a Mentos-and-soda fountain! Mentos are also fairly dense and sink rapidly, quickly creating bubbles that seed further bubbles as they rise. Drop several Mentos into a bottle of coke or lemonade, and a huge eruption of bubbles shoots out several meters high.
