June 15, 2008 -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. A classic experiment in chemistry is combining a small candy called Mentos with Diet Coke. Chemunicate creates commissioned graphics for chemistry researchers and institutions. But there have been no rigorous scientific studies of the reaction until now. 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.

How can you explain physical change with experiment? When you add Mentos to the bottle, youre drastically speeding up this process. 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. On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. The molecules are not chemically altered. The Diet Coke and Mentos experiments turn a sugar-free cola beverage and chewy candies into a geyser. He also shares personal stories and insights from his own journey as a scientist and researcher. In fact, its not really a reaction at all or at least its a physical reaction rather than a chemical one. 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! The team also investigated the total mass lost in the fountain and the influence of the sweets surface roughness. June 15, 2008 — -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Well, its probably not pretty. Write down what happened when you dropped the Mentos in the coke. The cookie is used to store the user consent for the cookies in the category "Other. Compare your notes on the experiment to the control group. Read on to find out more about how this Mentos and coke reaction works. To create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide's bonds with water in the Diet Coke must be broken. Im the owner and blogger here at SodaPopCraft.Com. The exception was citric acid, which did increase fountain height too, but which required slightly more than usually used in drinks. But can you swallow mentos or can you eat mentos can be answered fairly simply as to YES, you can only eat mentos or swallow them while being careful not to choke on them. All rights reserved. After all, its well known that dropping Mentos into a bottle of Diet Coke will cause a sudden geyser of soda foam to erupt. 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. The soda is saturated with carbon dioxide that is looking for a way to escape. Cutting, bending, dissolving, freezing, boiling, and melting are some of the processes that create physical changes. All the reactions took place in a bottle angled at 10 off vertical and the fountain trajectories were recorded on video. What does the inside of the candies look like? Be ready. Does the amount of Mentos affect the height of the explosion? As it sinks, the Mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a Diet Coke geyser. But opting out of some of these cookies may affect your browsing experience. Opening a soda generates the characteristic 'pop' and 'hiss' sound many are familiar with. It also means changing some factors may cause a larger or smaller physical reaction to take place. That means that all of the pieces of the reaction are there, but that they are simply rearranged. diet soda eschews these ingredients in the name of fewer calories, dishwasher soap and water to a soda bottle. Since the escaping gas either comes out in the form of a long burp or in foam expelled through vomiting, the issue stops once the soda has evacuated your stomach in one way or another.

The Mentos and Coke reaction is a popular science experiment that involves adding Mentos candies to a bottle of Coca-Cola.

124 lessons. Should more countries vaccinate children against chickenpox? WebWhat is Mentos and Coke Reaction in Human Body? Rough candy 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.

On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. As well as brewing my own homemade soda concoctions. Rough-surfaced mints without the surfactant did not create such large fountains. While this reaction may be entertaining to watch, it has no direct effect on the human body, if you swallow either. 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. Examples of physical change include, cutting paper, melting butter, dissolving salt in water, and breaking glass.

Summary. Generally, they found that carbonated water gave the smallest geysers, with sugar-sweetened beverages giving better results, and diet beverages better still.

It shouldnt be a regular trick in your party repertoire. The dissolved substances in the drink were stopping the smaller bubbles combining into bigger bubbles.

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. 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. In an experiment, you have two groups: an experimental group, and a control group. This is a commissioned Chemunicate graphic. Sugary drinks can contribute to many health conditions, including obesity, type 2 diabetes, and tooth decay. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve. Experiments in a 2006 edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke. Mentos are also fairly dense and sink rapidly, quickly creating bubbles that seed further bubbles as they rise. When soda is poured into a glass, most of the carbon dioxide remains trapped under the water (or liquid) thanks to its surface tension. 6 The physical process of But caffeine-free Diet Coke did just as well, suggesting that caffeine does not accelerate the reaction, at least at the normal levels in the drink. Very slowly and carefully, open a new bottle of colorless soda. As the carbon dioxide is less soluble at lower pressures, it starts to leave the drinkin the form of small bubbles. NEW CHALLENGE and it turned put great. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. 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.

Place a piece of wax paper on top of the cutting board. Steaming hot water bursts into the air with the crowd watching in awe. This will count as your control group. Make sure to check out our How many Mentos can you drop in while being able to keep the soda from spewing out of your mouth (i.e., how strong is your mouth vs the pressure released)? When the bottle stops spouting, stop recording. It is likely that these stories are exaggerated and have been spread on the Internet for entertainment purposes. The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. 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. This keeps the bubble growth going. Since objects do not become a different substance during a physical change, it is usually easy to reverse the change. Conclusion.

Christina graduated with a Master's in biology from the University of Louisiana at Lafayette. Let us know what you observed in your science experiment! As the bubbles get bigger, they detach from the Mentos and race to the top of the soda. Also, stand clear of the bottle after you add the Mentos. Mentos are dense candies, which aids the sinking process a factor the study explored by comparing reactions made with whole Conclusion. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. 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. 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. However, scientists are finding that theres more to this spectacular demonstration than meets the eye. No new substance is formed in a physical change; water moving between states of matter, a Popsicle melting, and a paper crumbled are examples of physical changes. Using the tape marks in the background, estimate the height of the spout. ), A tube the width of the Mentos. Tilt the cup and slowly pour the soda down the inside of the cup to make as few bubbles as possible. Diet Coke will work better than regular Coke for this experiment.

4. The crushed Mentos candies, however, are not as dense as the whole ones, which causes them to sink more slowly, creating a relatively small cola fountain, which should also leave more liquid in the bottle than the larger eruption with whole Mentos candies did. 2.
Mentos ingredients also help this reaction to some extent. Lower surface tension makes it easier for the bubbles to break out to the surface and attempt to escape. These bubbles form because of a disruption in the solution. As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption.

Tilt the cup and slowly pour the soda down the inside of the cup to make as few bubbles as possible. To unlock this lesson you must be a Study.com Member. 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. This in turns means that the carbon dioxide gas is more rapidly released. Wax paper Did what you hypothesize happen? In fact, its not really a reaction at all or at least its a physical reaction rather than a chemical one. Physics What is Mentos and Coke Reaction in Human Body? Mentos will result in the formation of a geyser in any carbonated liquid. Youll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. Like you did before, place your full cartridge on top of the flat index card, then line up where the opening of the bottle is with the opening of your cartridge. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. Preparation

A two-liter bottle of diet soda (diet soda makes for a much better reaction, but you can use regular soda if you like. 3. Background By dissolving quantities of the compounds in carbonated water, they were able to test each compound individually. 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 quantitiesusually found dissolved in commercial carbonated drinks. ), Tarantula Facts in 2023 Fun & Interesting Facts, 12 Michael Jackson Facts For Kids 2023 [Must Read], Mood in Literature (Definition, Examples & Case Studies) 2023, Antithesis Examples, Definition, Usage, and Popular instances. Was the eruption higher when whole Mentos candies were used compared with crushed candies? Diet Coke is preferred because its chemical properties result in the largest geyser. Materials science 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. The reaction results in a massive eruption of soda due to the rapid release of carbon dioxide bubbles from the soda. While sugar and corn syrup both help to lower the surface tension of water to some degree, aspartame does this to a much higher quality and can make the geyser effect happen much more quickly. [RAMUNE SODA FLAVORS], Will Cans Explode in Checked luggage? That paltry fifteen grams of carbon dioxide in the bottle might not sound like much, but as it comes out of solution in the bottleit can expand to take up up to 8 litres in volume. When you open a bottle of a carbonated drink, you release the pressure. The Diet Coke and Mentos experiment results from the nucleation of carbon dioxide from liquid to gas. Mentos are dense candies, which aids the sinking process a factor the study explored by comparing reactions made with whole Mentos are then added to the solution, and the observers can stand back and watch a geyser form. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. WebThe chemical reactions involved in dropping mentos candies into a bottle of diet coke make quite the spectacle! The reaction has been performed numerous times on television and the Internet, but has not been systematically studied. As , EL NORTE is a melodrama divided into three acts. Many people speculated that the geyser was However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. I wonder how a nitrogenated beverage would compare, since nitrogen bubbles are inherently smaller? 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. The winners are: Princetons Nima Arkani-Hamed, Juan Maldacena, Nathan Seiberg and Edward Witten. Chemistry As it sinks, the Mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a Diet Coke geyser. Tape the tube together on the side. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. As a reminder, molecules are two or more atoms linked by chemical bonds. Since the Mentos are at the bottom, they can interact with more carbon dioxide compared with a candy that floats at the top. 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. The reaction makes the beverage blow out of its bottle. Surface tension is the bond between molecules in the liquid. Status: False.

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. Let us know what you observed in your science experiment! Summary. The independent variable to this experiment is the Mento because it could stand alone and it does not depend on. When the bottle stops spouting, stop recording. Almost everyone in middle school or high school wondered what happens if you drink coke and mentos and has heard the urban legend: if you drink Coke and eat Mentos, youll explode! Claim: A mixture of Mentos and Coca-Cola killed two Brazilian children. Amanda has taught high school science for over 10 years. Bubble size, it turns out, is inversely proportional to the height of the Coke geyser; the smaller the bubbles, the greater the height achieved. Because no new chemical compounds are formed, the escape of CO 2 from a soda is known as a physical change. There are four steps that should be followed to get the classic eruption: Before starting the experiment, it's important to understand that the Coke and Mentos reaction is likely to generate a large, sticky mess. really cool seeing a systematic experiment on this. The team also investigated the total mass lost in the fountain and the influence of the sweet's surface roughness. Five common compounds in carbonated beverages were tested: aspartame, benzoate, linalool, citral, and citric acid. A carbonated challenge from Science Buddies, Key concepts However, consuming too much sugar can lead to a sugar crash, which can cause fatigue and lethargy. 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. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. No chemical bonds were created or broken. If you try this project with regular Coke, the eruption should still happen but its sugary content may make cleaning more difficult. Nucleation is the process by which a state of matter becomes another state of matter on its own. There really arent that many supplies you need to make a mentos and coke volcano. What could you do to make your eruption bigger? Because no new chemical compounds are formed, the escape of CO 2 from a soda is known as a physical change. Thanks for reading Scientific American. Examples of physical reactions are boiling or freezing water, breaking glass, and dissolving sugar WebNow remove the index card and let candies fall in and step away from the Mentos and coke volcano. How much liquid is left in the bottle? When you review the recordings, use slow motion and pause the recording when the spout is at its maximum height. That means that all of the pieces of the reaction are there, but that they are simply rearranged. A physical change occurs when the appearance of a substance changes but its chemistry remains the same. The change of matter which occurs without changing its chemical composition is called a physical change. Which reaction went higher, the whole or the crushed Mentos? Carefully remove the cap from the bottle and place the flat index card on top, covering the hole. One reason that our program is so strong is that our . 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. Remove the spent cola bottle and place a new full bottle in the same position, again making sure that it is level and stably standing straight. Mentos are dense candies, which aids the sinking process a factor the study explored by comparing reactions made with whole 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. Which beverages, candies or other things cause the largest and smallest fountains? When consumed in moderation, caffeine can increase alertness and improve mood. Note be sure to only try this experiment with a responsible adult! And you may not have a friend for a day or two until they forgive you. I would definitely recommend Study.com to my colleagues. How high did the eruption appear to go? Investigating further, it was found that when the substances were dissolved in water, the bubbles produced were smaller. Density is how much mass is in a given volume. Make sure you do it outside. Science of MentosDiet Coke explosions explained. Explosions Since there are so many nucleation sites on the Mentos, this happens incredibly fast, causing the huge eruption. Make sure the candies are in line with the mouth of the bottle.

The reaction has been performed numerous times on television and the Internet, but has not been systematically studied. Web1. Speed also matters, and the faster the Mentos sinks, the larger the eruption. Thus the Coke and Mentos reaction is a physical one, not a chemical reaction. Calculate the average height of the fountains for the whole and for the crushed Mentos. The Mentos and Coke reaction is a popular science experiment that involves adding Mentos candies to a bottle of Coca-Cola. 4.
