(Guinness was my inspiration on this thought :] ), also made me think of another experiment designed for guys doing dumb things: 
Observations and results
The Science of Coke and Mentos from EepyBird.com
Examples of physical reactions are boiling or freezing water, breaking glass, and dissolving sugar
Originallythe explanation for the effect was thought to be quite simple. Physical reactions
WebIf you haven't heard about the Diet Coke and Mentos Experiment then you have probably been living under a rock. The Diet Coke and Mentos reaction is a fun demonstration in chemistry and physics classes of many important concepts in thermodynamics, fluid dynamics, surface science, and the physics of explosions. And if you have rough candy with a high ratio of surface area to volume, then theres more places for the bubbles to go.. 
Have you ever taken a can of soda, shook it up, and given it to your friend? Tilt the cup and slowly pour the soda down the inside of the cup to make as few bubbles as possible. The cookie is used to store the user consent for the cookies in the category "Other. Thanks for reading Scientific American. 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. Your stomach is surrounded by many other internal organs that shift normally when you eat a large meal. And its a great way to learn about chemical reactions. 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. A classic experiment in chemistry is combining a small candy called Mentos with Diet Coke.
"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. Next, get ready to drop your Mentos into the Diet Coke. 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! However, scientists are finding that theres more to this spectacular demonstration than meets the eye. The proposed explanation for this is that the dissolved compounds may actually be affecting how thebubbles themselves behave, and it is this combined with factors relating to surface tension that influences fountain height. Examples of chemical changes are burning, cooking, rusting, and rotting. Because no new chemical compounds are formed, the escape of CO 2 from a soda is known as a physical change. WebNow remove the index card and let candies fall in and step away from the Mentos and coke volcano. Physical actions, such as changing temperature or pressure, can cause physical changes. Tilt the cup and slowly pour the soda down the inside of the cup to make as few bubbles as possible. The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites. A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. Use a tape measure and blue painter's tape to mark off the height from the top of the bottle in meters. We found that the max amount of mentos with the largest explosion was 4 mentos, it went 350 cm high. A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. 
It does not store any personal data. Because no new chemical compounds are formed, the escape of CO 2 from a soda is known as a physical change.
"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.". 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! COKE AND MENTOS. Preparation. When you melt an ice cube (H2O), you have a physical change because you add energy. Do a little bit of research about the ingredients of Mentos and soda. Line up where the opening of the bottle is with the opening of your cartridge. 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. Previously, scientists have tried to investigate why this is, and they suggest that the artificial sweeteners in diet forms of carbonated drinks, specifically aspartame and benzoate, might be responsible.

Any type of soda is pressurized to keep it fizzy inside the bottle.
Create your account. Though the surface of a Mentos candy may look smooth, at a microscopic level its full of pits, peaks, and craters, like a miniature version of the surface of the moon. Youll suddenly experience an upsurge of soda foam and will likely burp or vomit up large amounts of the stuff in seconds. 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. Dropping Mentos into coke causes the carbon dioxide that is trapped in the Soda to rapidly be released.
Crushed Mentos that fell more slowly created puny fountains that only travelled about 30 centimetres. Many people speculated that the geyser was

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 cookie is used to store the user consent for the cookies in the category "Analytics". However, ingesting Mentos and Coke separately can have various effects on the body. They suspected other compounds dissolved in the drinks might be affecting fountain height, so they carried out further tests on these compounds in isolation. Mentos are dense candies, which aids the sinking process a factor the study explored by comparing reactions made with whole Let us know what you observed in your science experiment! Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. Make sure to check out our Two index cards
this big guy just dropped another BOOMIN video so like it up. The Diet Coke and Mentos experiment results from an increased rate of nucleation. The reaction results in a massive eruption of soda due to the rapid release of carbon dioxide bubbles from the soda. Diet coke and mentos is a deadly combination that erupts as soon as one comes in contact with the other. What could you do to make your eruption bigger? The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites. Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. The team also investigated the total mass lost in the fountain and the influence of the sweets surface roughness. Status: False. The exception was citric acid, which did increase fountain height too, but which required slightly more than usually used in drinks. Diet coke and mentos is a deadly combination that erupts as soon as one comes in contact with the other. Materials
Then step back without tipping the bottle over or disturbing the reaction. Published Nov 8, 2006. When you open a bottle of a carbonated drink, you release the pressure. really cool seeing a systematic experiment on this. Finally, making your soda bottle warmer instead of colder will make the geyser higher and faster. Be sure to wear eye protection when putting the candies into the cola! 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. When you add Mentos to the bottle, youre drastically speeding up this process. (Can You Bring Cans On A Plane). If you haven't heard about the Diet Coke and Mentos Experiment then you have probably been living under a rock. Speed also matters, and the faster the Mentos sinks, the larger the eruption. Status: False. 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. "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. The carbon dioxide, once freed from its bonds, forms small bubbles that are lighter than water and which want to rise. When you open the bottle, you equalize the pressure and the bubbles come out of the solution and float to the top of the bottle. Since the Mentos merely facilitates the creation of bubbles, the candy will continue to act as a catalyst for carbon dioxide bubble formation until all of the surrounding CO2 has been exhausted in the bottle. V I Cothran, J T Kuntzleman, D J Campbell; Celebrating Sant Jordi (Saint Georges Day) Chemistry with ICIQ, Reversible Reactions, Equilibrium, and Le Chteliers Principle, WEEKEND POST 128 | HEATHER GOESCH NUTRITION, Previously, scientists have tried to investigate why this is, http://dx.doi.org/10.1021/acs.jchemed.6b00862. Status: False. Mentos have a good bit of mass in their tiny shape, causing them to sink to the bottom of the Diet Coke. Extra: Do this activity again but instead of testing whole Mentos versus crushed, compare warm versus cold Diet Coke. In each case, the physical properties change but the chemical properties remain the same. 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. Which process involves a physical change? Safety Tip!! What are the signs of a physical reaction? Do Not Sell or Share My Personal Information. 2. 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. Its one of the most popular science demonstrations: Pop a handful of Mentos candies into a bottle of Coke, and a fountain of bubbles rapidly spurts from the open bottle, often over a metre into the air. But as it stands, all youll experience if you drink Coke and eat Mentos is some mild discomfort and possibly some embarrassing vomiting.

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. Read on to find out more about how this Mentos and coke reaction works. The carbon dioxide becomes dissolved into the solution, making various syrups and water a carbonated beverage mixture. 6 The physical process of Carefully remove the cap from the bottle and place the flat index card on top, covering the hole. Mentos has thousands of tiny bumps over its surface even though the candy might look smooth to the naked eye. The rough surface of the candy creates friction where the heavier carbon dioxide molecules can sink and break away from their bonds with the water surrounding the. Place a straw in the soda and look at the straw from the side. In fact, its not really a reaction at all or at least its a physical reaction rather than a chemical one. Write down what happened when you dropped the Mentos in the coke. Thus the Coke and Mentos reaction is a physical one, not a chemical reaction. What is physical and chemical change with example? Drop your Mentos in the Diet Coke and step back - it's about to get messy!
The dependent variable is the the Diet Coke with the mentos because it depends on the mentos to have a chemical response. 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! So, any rough surface inside the bottle will cause the carbon dioxide molecules to cluster together in a process called nucleation, which forms bubbles. 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. You can expect a large eruption. Make sure the candies are in line with the mouth of the bottle. What makes something a physical reaction? Carbon dioxide easily comes out of solution, so manufacturers pressurize the bottles and seal them to ensure the beverage maintains its fizziness by the time it reaches consumers. 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. Instead, the vigour of the jets depends on various factors that affect the growth rate of carbon dioxide bubbles. Rough-surfaced mints without the surfactant did not create such large fountains. Video camera with either a tripod or a helper to take the images (optional)
It is always recommended to consume any food or drink in moderation and to be aware of the ingredients and potential side effects. If you videotaped the reactions, you can watch your videos now. 4. Mentos are a type of candy that contains sugar, glucose syrup, and a variety of flavors. COKE AND MENTOS. You can try testing different kinds of carbonated beverages, different kinds of candies with different shapes and textures or using other things to start the reaction, like rock salt, pennies or dice. Water molecules like to be next to other water molecules, so basically anything that you drop into the soda that disrupts the network of water molecules can act as a growth site for bubbles, Coffey told New Scientist. Note be sure to only try this experiment with a responsible adult! When you review the recordings, use slow motion and pause the recording when the spout is at its maximum height. While this reaction may be entertaining to watch, it has no direct effect on the human body, if you swallow either. What is a physical reaction example? More to explore
As it sinks, the Mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a Diet Coke geyser. Speed also matters, and the faster the Mentos sinks, the larger the eruption. June 15, 2008 -- The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation.
