Drop some Mentos sweets into a bottle of Diet Coke and a geyser-like fountain will whoosh into the air – at last, there's a scientific explanation. Have you ever wondered whether or not the Mentos trick works with regular coke? Does it work with other drinks? Here's the answer! Most people are aware that both regular and diet soda are bad for your health, but when it comes to which is worse, things get a bit tricky. The truth is they are. Diet Coke (called Coca-Cola Light in some countries) is a sugar-free soft drink produced and distributed by The Coca-Cola Company. Unveiled on July 8, 1982 and. About The Extreme Diet Coke & Mentos Experiments This is the video that started it all: a backyard experiment became a cultural phenomenon. This is what happens when. Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. The reaction is so intense, you. Key concepts Chemistry Physics Materials science Carbonation Physical reactions Explosions Introduction Have you ever seen the Diet Coke and Mentos experiment that is. One of the most popular experiments of modern times is the Diet Coke and Mentos Geyser. Made popular by Steve Spangler, this experiment is a lot of fun and sure to. ![]() Mentos - Wikipedia.

The mint is basically miniature Mentos roughly the size of Skittles, and they come in mixed flavors: white grape (green), lemon (yellow), strawberry (pink), orange (orange), raspberry (blue), and cherry (red). During the 2. 01. FIFA World Cup, a Brazilian team Mentos was released in Brazil to support the national team. The mint was green apple and orange flavors. In some countries, the Mentos Ice candy can be bought in flavors such as, cherry (red), green apple (green) and grape (purple). Ume, Fuji apple, and Pine Fresh (pineapple) Mentos are sold exclusively in Japan. Flavors only available in certain countries; Enigma (Czech Republic) Rainbow (UK and US) Ume (Japan) Fuji Apple (Japan) Pine Fresh (Japan) Ice (Canada)Marketing. Shot in South Africa, individuals facing various day- to- day dilemmas consume Mentos and are subsequently inspired to solve their problems at hand in a creative, often- humorous fashion. For example, a job interviewee sits on a freshly painted bench, staining his suit, and then solves the problem by rolling around on the bench until his suit has pinstripes. Another features a woman whose parked car is boxed in; she calls a crew of construction workers over who lift her car onto the road for her. These unusual behaviors are typically witnessed by nearby, sometimes antagonistic characters, and a roll of Mentos is boisterously displayed by the commercial's respective protagonist to the observer as an explanation for their actions. The ad campaign was parodied in multiple television shows and music videos. It displays a man sitting near a business water tank, and pops a piece of Mentos Gum in his mouth. A woman then walks by, pushes his nose up, and proceeds to kiss him, the kiss making a slurping sound. The woman then wipes her mouth, and pushes the man's nose back down as if to close it. The phrase . However, more recently, the slurping, kissing sounds have been removed. TV ads are generally based on a situation where a person facing a problem suddenly has a brainwave after eating Mentos and solves the problem innovatively. Another Mentos advert highlighted the multicolored variety of the sweets by showing a scene where two young lovers are sitting in a living room. The teen girl screams as a small seemingly harmless spider crawls across the carpet. This prompts the teen boy to get off the couch that they are sitting on and pick up the spider, only to be violently thrown about by the spider. The slogan at the end reads . Myth. Busters concluded that the potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos, all contribute to the formation of the foam. Myth. Busters reported that when fruit- flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas mint- flavored Mentos (with no such coating) added to carbonated drink formed an energetic eruption, supporting the nucleation- site theory. According to Myth. Busters, the surface of the mint Mentos is covered with many small holes that increase the surface area available for reaction (and thus the quantity of reagents exposed to each other at any given time), thereby allowing CO2 bubbles to form with the rapidity and quantity necessary for the . A paper by Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina, confirmed that the rough surface of the Mentos candy helps speed the reaction. Coffey also found that the aspartame in diet soda lowers the surface tension and causes a bigger reaction, but that caffeine does not accelerate the reaction. In some cases, dissolved solids that increase the surface tension of water (such as sugars) also increase fountain heights. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in water. The unofficial record, reached in Myth. Busters, was over 3. Retrieved 1. 6 February 2.

Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. The reaction is so intense, you can make a rocket propelled by the resulting geyser. But what's the science behind this reaction? In June 2. 00. 8, Dr. Tonya Coffey of Appalachian State University and her physics students published a paper on the phenomenon in the American Journal of Physics. They were inspired by a 2. Myth. Busters episode that, according to the paper, . When this happens fast enough, you get a nice Diet Coke fountain. In non- science speak, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. Bubbles will continue to form on the porous surface and the process will repeat, creating a nice, foamy geyser. In addition to that, the gum arabic and gelatin ingredients of the Mentos, combined with the potassium benzoate, sugar or (potentially) aspartame in diet sodas, also help in this process. In these cases, the ingredients end up lowering the surface tension of the liquid, allowing for even more rapid bubble growth on the porous surface of the Mentos—higher surface tension would make it a more difficult environment for bubbles to form. You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water. Size Matters. Another factor that contributes to the size of the geyser is how rapidly the object causing the foaming sinks in the soda. The faster it sinks, the faster the reaction can happen, and a faster reaction creates a bigger geyser; a slower reaction may release the same amount of foam overall, but will also create a much smaller geyser. This is another reason Mentos works so much better than other similar confectioneries: The candies are fairly dense objects and tend to sink rapidly in the soda. If you crush the Mentos, so it doesn’t sink much at all, you won’t get a very dramatic reaction. The temperature of the soda also factors into geyser size. Gases are less soluble in liquids with a higher temperature, so the warmer your soda is, the bigger your Mentos- induced geyser will be. This is because the gases want to escape the liquid, so when you drop the Mentos in, the reaction happens faster. What Doesn't Work. While caffeine is often cited as something that will increase the explosive reaction with the soda, this is not actually the case, at least not given the relatively small amount of caffeine found in the typical 2- liter bottle of soda generally used for these sorts of Diet Coke and Mentos reactions. You’ll also sometimes read that the acidity of the soda is a major factor in the resulting geyser. This is not the case either. In fact, the level of acidity in the Coke before and after the Mentos geyser does not change, negating the possibility of an acid- based reaction—though you can make such an acid- based reaction using baking soda.
