Buy chewing up the candy you have destroyed all the little pores that result in the large surface area responsible for the nucleation reaction. * Citric acid and bicarbonate of soda should release lots of carbon dioxide. It turns out that Mentos have a very porous surface, with thousands of tiny indentations, perfect for nucleation. To see this, recall that dissolved CO 2 reacts with water to form carbonic acid (H 2 CO 3 ): 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. The Mentos experiment can be done with any soda or carbonated liquid. You'll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. Likewise, with regard to "One year before the same accident happened with another boy in Brazil," once again the news is silent regarding such a death. I'm addicted to Crystal Pepsi: https://youtu.be/qEjy3dS6COs \"HAVE A CRYSTAL PEPSI DAY!\" - L.A. (2008). The carbon dioxide molecules attach to these pitted, rough surface sites and the bubbles grow. Once you drop the Mentos into the coke, stand back as it's VERY explosive. The gum is similar to the stuff in mentos, gum Arabic, which releases gas from fizzy drinks even if added alone. 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. You should also follow any safety advice and precautions listed on the product label. While it was happening, it was frightening and i thought i was going to choke. The eruption should happen instantaneously, so make sure to get out of the way to avoid being covered in sticky soda. That way you can do maybe a hundred at once. She is a current PhD student in biology at Wake Forest University, and has been teaching undergraduate students biology for the last three years. However, you may do untold damage to your stomach. Inflation from diet coke and mentos can cause an increase in blood pressure, heart rate, and body This was demonstrated in an experiment that tested 15 types of carbonated beverages with Mentos. Try a new bottle of Diet Coke and a new package of Mentos. 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. But the process is constant and grows exponentially. Now, make a Mentos-and-soda fountain! The team also investigated the total mass lost in the fountain and the influence of the sweet's surface roughness. What Chemical In Mentos Makes Coca-Cola Explode? This is a messy experiment. Those who have disregarded common sense and tried such anyway report that the intensity of the reaction forces the mouth open, thereby releasing most of the gas and foam into the wild, as it were, rather than keeping them contained within the person. What Is The Chemical Structure Of Coca-Cola? Numerous video clips of "Mentos eruptions" exist on the Internet; one needn't search all that diligently to stumble across scads of them. Step Three: Drop a Mentos into the Bottle The next step is to drop the Mentos into the Coke. Mentos that drift peacefully through the soda will have a weaker reaction in comparison. I think the cracks in the mentos will disappear during consumption. But, it is true that a violent reaction occurs when you put Mentos into a bottle of Coke. 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. It certainly wont be comfortable and Mentos, but there arent any real health risks from doing so. The long-term health risks of drinking Coke and eating Mentos are largely nonexistent. Pop a bottle and have a browse. From left to right: action of five Mentos candies (per bottle) with Perrier, classic Coke, Sprite, and Diet 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 to be expelled from its container. This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. Another trick I do is stuffing baking powder into large 1 gram empty medicine capsules. 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. One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. Surely, then, you dont want to eat Mentos while drinking Coca-Cola, lest this reaction occurs in your stomach. For instance, in photosynthesis, water and carbon dioxide are transformed into sugar. 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). 4. It's every 8th grader's dream either you spew a volcano of soda or you explode. One year before the same accident happened with another boy in Brazil. Scooping up powder and cramming it into them for an hour sucks :/. Christina graduated with a Master's in biology from the University of Louisiana at Lafayette. However, this stomach did swell up a lot which would probably result in vomiting, just as we saw in the YouTube video. 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. Please contact for permissions. Forgot password? 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. half a roll) in the test tube. Then I immediately chugged another half liter or so of coke. What is the Difference Between Convection and Induction Cooking? Diet Coke and Mentos: What is really behind this physical reaction?. 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. [RAMUNE SODA FLAVORS], Will Soda Cans Explode in Checked Baggage? The results of the experiment are shown in the illustration below: The types of solutes in the soda mixture also have effects on the height of the fountain. Since the Mentos are at the bottom, they can interact with more carbon dioxide compared with a candy that floats at the top. Doesn't work. Youll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. What is it with this experiment with soda and Mentos that causes this explosion to shoot so far into the air? 1. Put it on the bottle in such a way that all the mentos in the tube are . This forces the liquid to overflow and shoot out. The hands-on experiment involves dropping several Mentos Chewy Mints into a bottle of Diet Coke, which can cause a stream of the diet cola to shoot many feet into the air within seconds. much more than one liter could give me on its own. 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. Diet Coke is just more carbonated. The Coke-Mentos experiment is one of the most popular science experiments and also one of the most well-known. Whats up people. COCA COLA VS MENTOS || Sprite vs Mentos 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. The original ingredients of Coca-Cola contained cocaine from coca leaves and caffeine-rich extracts from kola nuts. Additionally, the stomach has a couple ways of expelling excess gases. Was Coca Cola the only Soft Drink to Contain Cocaine? * Fizzy water and gum tragacanth. They are dense and sink. Sign up to read all wikis and quizzes in math, science, and engineering topics. Acids and bases are common classes of chemicals that react with each other and with water. Still not quite getting it? Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. NEW CHALLENGE and it turned put great. "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.". What is the science behind the mentos and coke experiment? Thus, the texture of Mentos alone increases the rate of nucleation. 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). Either way, it's funny. In order to understand why Coke and Mentos react so explosively, you have to understand how both ingredients work in the first place. 2. The mints are small oblate spheroids, with a slightly hard exterior and a soft, chewy interior.. Is the How Coca-Cola Reacts to Stomach Acid Video Real? You can expect a large eruption. Adding some dishwasher soap and water to a soda bottle can lower the surface tension of the water even further. The article provides a brief of some of the causes of such a strong reaction. This lesson analyzes this classic experiment in more detail to understand the following learning objectives: To unlock this lesson you must be a Study.com Member. Concerning getting powder into capsules, you can get or make something for this. Mentos react with Diet Coke because their rough surfaces provide suitable sites for rapid growth of carbon dioxide bubbles, according to Mental Floss magazine. "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.". However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. Slowly and carefully open a new bottle of Diet Coke. It is a physical reaction rather than a chemical one. 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. They are typically sold in rolls which contain 14 mint . Shake bottle so that mentos and Diet Coke mix. Im the owner and blogger here at SodaPopCraft.Com. 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. Each bottle tested had a two-litre capacity, and eleven Mentos were introduced to each bottle.
