Put it on the bottle in such a way that all the mentos in the tube are . The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. Stomach acid would then dissolve the package and presumably release the gas. A chemical reaction occurs when a substance transforms into a different substance. In effect, you have rendered the candy harmlessits just candy. Christina graduated with a Master's in biology from the University of Louisiana at Lafayette. Effects of diet coke and mentos on the body. Opening a soda generates the characteristic 'pop' and 'hiss' sound many are familiar with. Gas becomes much less soluble in warmer environments; cold soda stifles the gas creation effect and will make your geyser weaker. Diet Coke and Mentos - . In effect, you have rendered the candy harmlessit's just candy. Example: [Collected on the Internet, 2006]. The present-day ingredients of Coca-Cola classic are a little different: Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. But i think nucleation sites are the way to go, not an actual chemical reaction. 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. It works fine, the coke fizzes because of the cracks in the mentos, not the chemical makeup. 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. It's the same chemistry, but a different magnitude. How Long Do They Last? The bubbles' buoyancy coupled with their rapid growth, causes them to rise to the surface, resulting in an eruption of foamy diet soda. This is likely for two reasons. Create your account. Drop your Mentos in the Diet Coke and step back - it's about to get messy! The short answer is that eating Mentos by chewing them up while drinking Coca-Cola, or any other soda, will little to no effect. Is the How Coca-Cola Reacts to Stomach Acid Video Real? Why is Diet Coke a better choice for this experiment than other sodas? A few questions i would like answering: -how much of each should i consume? The result is a massive eruption of foam, shooting stories high into the air. Materials: 1 pkg. Additionally, the stomach has a couple ways of expelling excess gases. What they found was what I suspected, that the actual act of drinking the soda released much of the carbon dioxide. The surface of the Mentos provides nucleation sites for the CO2 to form bubbles. I could feel my belly expanding to the point of discomfort. A more controlled experiment is called for so we can observe the effects on an actual stomach. COCA COLA VS MENTOS || Sprite vs Mentos 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. But, it is true that a violent reaction occurs when you put Mentos into a bottle of Coke. It is likely that these stories are exaggerated and have been spread on the Internet for entertainment purposes. 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. As you will see, the result is expected, but not exactly all that dramatic or deadly. One reason is their large surfacetovolume ratio, which allows millions of bubbles to form from each piece. One enterprising group made a mentos and diet coke-powered rocket. So what happens if you drink coke and eat Mentos? Sign up, Existing user? I did this all in less than a minute. They are so small you cant even see them, but they number in the thousands, at least. 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. Anything can cause nucleation, like a lemon or a jelly bean. But i think nucleation sites are the way to go, not an actual chemical reaction. The video is, of course, a joke and not real although many people claim it looks real. You can view this video on YouTube. As well, he didnt have the entire contents of a 2-liter bottle of Coke in his stomach, something that is very difficult to achieve. 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. Shake and inflate. If you looked at it with a microscope, it would look pitted, just like a golf ball. This year, I adapted my somewhat free-wheeling "wing it" approach to this experiment to instead have students research, test, and adapt as needed. What chemical in Mentos makes soda explode? Thus, the rates of nucleation are further increased. I pack, and 1-2 cans mountain dew. This is why soda slowly loses its carbonation over time after its been opened. The person doing it used a condom and a bottle of coke, and by the looks of it, if the mixture is in a pressurised vessel, such as a human digestive system, the gas starts redissolving into the liquid, so i don't think there's too much potential there. This was a total disaster! 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. Imagine a huge geyser erupting at Yellowstone National Park. 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. Already have an account? That year, the grist being run through the rumor mill included the sad tale of. Ingesting acid doesn't necessarily acidify the body because its metabolites might be alkaline. 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. As the outlet explains, "those gas bubbles want to escape," and "to create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide's bonds with water in Diet Coke must be broken.". Ok, so I was curious about this as well. As the bubbles get bigger, they detach from the Mentos and race to the top of the soda. Diet soda stereotypically has a better reaction than regular soda. But the bubbling youll feel on your insides isnt easy or gentle, so it shouldnt be performed regularly. Nucleation is the process by which a state of matter becomes another state of matter on its own. 460 Words2 Pages. He was claimed to have died after eating Pop Rocks candy with soda. 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. When Diet Coke and Mentos join, the result should be a large fountain of foamy soda that erupts from the bottle. Pop a bottle and have a browse. Why do Mentos and Diet Coke react so strongly? Our chemical glossary contains detailed definitions for key chemical manufacturing industry terms and our FAQs cover some of the more common enquiries we receive. Another factor is that the coatings of Mentos contain gum arabic, a surfactant that further reduces surface tension in the liquid. Surfactants lower the surface tension between two liquids, a liquid and a solid, or between a gas and a liquid. 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. Step 3: Shake and Launch! So, any rough surface inside the bottle will cause the carbon dioxide molecules to cluster together in a process called nucleation, which forms bubbles. Enrolling in a course lets you earn progress by passing quizzes and exams. This in turns means that the carbon dioxide gas is more rapidly released. 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. Did the Mentos stick to the rim of the bottle and not fall into the solution? Water molecules are polar and attracted to each other. Then drink a little over half slowly in give or take 2 min. Procedure: Stack the Mentos candies (approx. The Diet Coke and Mentos geyser is the result of a physical process rather than a chemical reaction. Non-diet cola doesn't work at all because of the sugar. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual. Thus, the texture of Mentos alone increases the rate of nucleation. NEW CHALLENGE and it turned put great. However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. 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. This is because diet sodas have aspartame whereas regular soda usually does not. Thankfully, theres already a well-known escape hatch located at your mouth. It's true that most of the people that do it do indeed inflate from simply having that much soda in them, but if you can hold the gas down I don't think there's anything stopping you from inflating. 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. Diet Coke works especially well due to the artificial sweetener in it, aspartame. The team also investigated the total mass lost in the fountain and the influence of the sweet's surface roughness. Numerous video clips of "Mentos eruptions" exist on the Internet; one needn't search all that diligently to stumble across scads of them. Since the escaping gas either comes out in the form of a long burp or in foam thats expelled through vomiting, the issue basically stops once the soda has evacuated your stomach in one way or another. 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 Coke-Mentos experiment is one of the most popular science experiments and also one of the most well-known. also, i had to lay down to hold in the gas. When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. Collect the following materials: Place the pennies on a flat surface. Here's an experiment to try at home regarding surface tension. But why is it called the "Diet Coke and Mentos Experiment" and not the "Coke and Mentos Experiment?" Chalk doesn't dissolve in water, so it should provide nucleation sites without getting soggy. Are There Any Long-Term Health Risks Eating Mentos & Soda? 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.
