Experiment: Coca Cola, Mentos and Baking Soda! It's not what you would call a chain reaction, because that's something else in chemistry terms, but it's a cascade whereon all of a sudden, all of the CO2 that was contained in the liquid is suddenly not as attracted to the liquid as it was before, because of this slight change in the chemistry that occurs." We also tried it with coloured mentos and mint Mentos. The reaction is … The eruption you get when you mix Mentos and Coke is generated by the rough coating of the candy, which causes lots of bubbles to form rapidly on its surface when it’s placed in a carbonated beverage. A tube the width of the Mentos. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. 5:18.

Make sure you drop in all the Mentos candies at once. Experiment Coca cola VS Mentos in the Pool AND Coca Cola vs Mentos Underground. Answer Save. Don't open the bottle of soda until you're ready to go. Log in here. Probably one of the most interesting experiments with Coca Cola and mentos. Coca-Cola is a carbonated beverage that is full of dissolved carbon dioxide. This is essentially speeding up the process that makes sodas fizzy. The engineer explains that the yellow nose cap is full of mentos, while the body is full of pressurized diet coke. (2008). ... and creates a volcanic eruption of cola. Bottled sodas are kept under pressure so that more carbon dioxide can be forced into solution. Previous article Grandma heckles bodybuilders – part 1; movlogs. One roll of Mentos candies. June 15, 2008 — -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. ... Posts should be able to elicit a reaction of 'that is next level' from viewers. The exception was citric acid, which did increase fountain height too, but which required slightly more than usually used in drinks. The goal is to keep as much dissolved carbon dioxide in the bottle as possible. When the pressure is released, the carbon dioxide is forced out of solution and makes little gas bubbles. Yes, we have all seen coca-cola and mentos, but this time its on steroids. You can also increase the effect by adding more surfactants to the soda before you add the Mentos, like adding a … There's a lot of carbon dioxide dissolves in the soda, which gives it its fizz. Experiment Coca cola VS Mentos in the Pool AND Coca Cola vs Mentos Underground. They provide a surface for the carbon dioxide bubbles to form on, and allow them to form much more rapidly. 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 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. Facebook Comments. Instead it is a physical reaction. Phosphoric Acid molecules attach to the milk giving them more density and separate out while the remaining liquid that makes up the milk and cocoa cola now being lighter floats on top. If Coca Cola is put in a balloon and Mentos is placed next to it, when the balloon is stung the reaction will be impressive. It just won’t be nearly as awesome.) The slide show claims that the event had been reported in the media and provoked a public reaction. However, scientists are finding that there’s more to this spectacular demonstration than meets the eye. Generally, they found that carbonated water gave the smallest geysers, with sugar-sweetened beverages giving better results, and diet beverages better still. I am a … V I Cothran, J T Kuntzleman, D J Campbell; This Week in Chemistry – Glow-in-the-dark Fungi Mechanisms, and Lithium Battery Fade Causes, This Week in Chemistry – Making Ibuprofen Last Longer, and the World’s First Nanocar Race, WEEKEND POST 128 | HEATHER GOESCH NUTRITION, Previously, scientists have tried to investigate why this is, http://dx.doi.org/10.1021/acs.jchemed.6b00862. Setelah melakukan serangkaian percobaan dan analisa, jawaban dari fenomena ini melibatkan beberapa faktor fisika, seperti kekasaran permukaan Mentos, pengaruh tekanan permukaan, dan juga kecepatan Mentos turun ke dasar botol. The gas form of carbon dioxide bonds with the water molecules present in the cola. mr pagalpanti. SHARES. [1] Other factors that affect the growth rate or total number of carbon dioxide bubbles also changed the geyser's height, such as temperature and the original surface tension of the soda.

Experiment: Coca Cola, Mentos and Baking Soda! Calculate the average reaction time, geyser height, and soda volume remaining for the trials using whole Mentos and the trials using crushed Mentos. The ingredients are coca-cola, mentos, looks like dish soap, and a secret ingredient. A Youtuber subbed Mentos for an enormous quantity of baking ... of 10,000 liters of Coca Cola. That paltry fifteen grams of carbon dioxide in the bottle might not sound like much, but as it comes out of solution in the bottle it can expand to take up up to 8 litres in volume. It needs to be wide enough to use as loader for the Mentos. Like most chemical reactions, the process occurs more quickly at a warmer temperature. It's the same chemistry, but a different magnitude. Sign up to read all wikis and quizzes in math, science, and engineering topics. GIRADOR DE COCA COLA COM MENTOS (COKE AND MENTOS EXPERIMENT) - Caduzinho Carvalho. The project was eventually published in the American Journal of Physics. A slightly different experiment with Cola and Mentos in which they wanted to highlight their reaction. For this, a sand volcano was created and Coca Cola and Mentos had the reaction … A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. The result is an impression both due to the fact that many Mentos were used and the same experiment was used which made everything look like a volcano. 5 Answers. This video is unavailable. Your average two litre bottle of Coke will contain about fifteen grams of dissolved carbon dioxide. Of course, the different substances dissolved in carbonated drinks don’t act in isolation, and they may also interact with one another to increase or decrease the height of the coke fountain. So you won’t get the same reaction in your stomach. Sign up, Existing user? 4:29. Why is it so? Already have an account? Originally the explanation for the effect was thought to be quite simple. #VolcanoShow #220l #Cola What will happen if you mix 220 liters of cola in a huge barrel with mentos and baking soda? Bubble size, it turns out, is inversely proportional to the height of the Coke geyser; the smaller the bubbles, the greater the height achieved. Look. Coca cola and the mentos. 2. The chemical reaction between the Mentos and Diet Coke reduce the surface tension on the top of the water allowing the gas created through nucleation to waste less energy breaking the surface tension as it dispels the soda out the mouth of the bottle in what is observed as the fountain or geyser. do u need to untwist the cap when u throw the coke on the ground. Place it on a flat area outside where it is OK to get wet with soda. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve. By dissolving quantities of the compounds in carbonated water, they were able to test each compound individually. What will happen if Diet Coke and Mentos react. You burp; and maybe have a tummy ache; and might vomit. Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. And if you add a big enough surfactant, you get a geyser. It needs to be wide enough to use as loader for the Mentos. The results aren’t fully explained by the previous theory relating to surface tension. Their suggestion was that these compounds lower the surface tension of the liquid, which allows bubbles to form quicker. The Diet Coke and Mentos geyser is the result of a physical process rather than a chemical reaction. Basically the Mentos start to dissolve, and it's like tripping a switch. This deeply satisfying science clip, filmed in Poland on August 18, shows an explosion of foam and surprising resemblance of a lava lamp, as the chemical reaction occurs. 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. When the bubbles are smaller, there is a greater surface area for the carbon dioxide still dissolved in the solution to escape into, so the degassing of the carbonated drink happens faster – giving a higher fountain. HYPOTHESIS: I think that the number of Mentos will affect the height of the explosion because there are more physical reactions happening. A two-liter bottle of diet soda (diet soda makes for a much better reaction, but you can use regular soda if you like. Dropping Mentos into a bottle of diet soda causes a physical reaction: as they fall through the soda, the Mentos candies break the bonds between the carbon dioxide and water (the combination that makes soda fizzy), releasing the carbon dioxide gas up and out of the bottle. Super reaction. Hypothesis: If we drop four uncoated Mint Mentos into 2-Liter bottles of Carbonated Water, Coca Cola, and Diet Coke, then the artificial sweetener of the Diet Coke will cause it to produce the highest eruption. take a mouthful of soda and drop in a Mentos. beverlyfannie8353. (kids, this is rhetorical – do not actually try this), […] at the chemistry behind those fizzy Coke and Mentos […], Explorations of everyday chemical compounds, on The Secrets of the Coke and Mentos Fountain. does it only work with white mint Mentos? Volcano Eruption | Experiment: Coca-Cola and Mentos Reaction Though the surface of a Mentos candy may look smooth, at a microscopic level it’s full of pits, peaks, and craters, like a miniature version of the surface of the moon. Forgot password? Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. [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. Even after this event and reports in various means of media provoked apalled public reaction, Coca-Cola and Mentos have issued no public statements. The proposed explanation for this is that the dissolved compounds may actually be affecting how the bubbles themselves behave, and it is this combined with factors relating to surface tension that influences fountain height. Email claims that children have died after consuming Diet Coke and Mentos together. The Diet Coke and Mentos reaction is a fun demonstration in chemistry and physics classes of many important concepts in thermodynamics, ... Coke, Coca-Cola Classic, Caffeine Free Coca-Cola Classic, If Coca Cola is put in a balloon and Mentos is placed next to it, when the balloon is stung the reaction will be impressive. Investigating further, it was found that when the substances were dissolved in water, the bubbles produced were smaller. This may be the focus for further experiments. In this video, we will make a hand made volcano from sand, Coca-Cola and mentos, and also add a secret ingredient. Science teachers are well aware that some types of carbonated drinks work better than others for this demonstration; for example, Diet Coke usually gives a higher fountain than regular Coke. Facebook Comments. But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! What is the most reasonable hypothesis to explain the difference? Their results showed that increasing the levels of all of these compounds increased the heights of the fountains obtained by as much as six times when Mentos were added, and at quantities usually found dissolved in commercial carbonated drinks. Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. More recently, chemists at Spring Arbor University in the United States tested a range of different carbonated drinks and found that the height of fountains varied between different products. Mentos mint candy Diet cola A variety of containers with varying sized opening A narrow test tube wide enough to fit the candy [Klutz and others make a delivery contraption that is easier.] We tried it with cola and lemonade. This graphic is based on the following paper: New demonstrations and new insights on the mechanism of the Candy-Cola soda geyser  – T S Kuntzleman, L S Davenport, V I Cothran, J T Kuntzleman, D J Campbell; J Chem Educ; Link: http://dx.doi.org/10.1021/acs.jchemed.6b00862. Diet Coke’s reaction was the biggest and an average of only 275 mL was left in the bottle. The last soda I tested was Diet Coke. Coffey, T. There is an urban legend that eating mentos while drinking soda could cause a person's stomach to burst. Both worked. mr pagalpanti. Coca-Cola’s amount left was an average of 308 mL. Their explanation is this process called nucleation. Probably one of the most interesting experiments with Coca Cola and mentos. 61. The eruption you get when you mix Mentos and Coke is generated by the rough coating of the candy, which causes lots of bubbles to form rapidly on its surface when it’s placed in a carbonated beverage. An index card (picture below) The Mentos And Coke Volcano Experiment Five common compounds in carbonated beverages were tested: aspartame, benzoate, linalool, citral, and citric acid. Why does the Coke and Mento Rocket work? Experiment: Coca Cola VS Mentos & Fanta VS Mentos. The basic science of the Coke and Mentos reaction is fairly straightforward. Their first video, The Extreme Diet Coke & Mentos Experiments, took the idea of dropping Mentos into soda and turned it into one of the best known viral videos of all time. Relevance __A_YAHOO_USER__ Lv 7. Making Lots of Bubbles 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. As to why diet sodas like Diet Coke produce such a bigger reaction, it’s because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. A rougher candy surface translates to more places for bubbles to grow, or more nucleation sites. Additionally, the stomach has a couple ways of expelling excess gases. 1000 mentos Volcano Eruption and Sprite and Cola Baloons with 2000 mentos reaction. They suspected other compounds dissolved in the drinks might be affecting fountain height, so they carried out further tests on these compounds in isolation. Science teachers are well aware that some types of carbonated drinks work better than others for this demonstration; for example, Diet Coke usually gives a higher fountain than regular Coke. 5:47. See more. Most Coca-Cola is kept carbonated by a sealed bottle, which creates a pressurized environment where the carbonated gas can’t escape until the cap has been broken off or opened. QUESTION: Does the number of Mentos affect the height of the explosion when added to Diet Coke? Logbook Fizz that’s almost like a mist. Originally marketed as a temperance drink and intended as a patent medicine, it was invented in the late 19th century by John Stith Pemberton and was bought out by businessman Asa Griggs Candler, whose marketing tactics led Coca-Cola to its dominance of the world soft-drink market throughout the 20th … To be more viscous, which gives it its fizz the slide show claims that children have after.
