**Mentos and Pop Experiment**. **Jasmine Futrell-McGee**. **Max Cowles** In the Mentos and Pop Experiment three different types of Mentos Candies including the original Mint Mentos, Strawberry and Fruit, will be combined with four different carbonated beverages including Pepsi, Diet Pepsi, Coke and Diet Coke. Upon the combination of these products, a fountain of foam will be created, thus leading to a loss of original liquid. The bottles of pop will be measured before and after the Mentos have been placed into them. The masses that are taken will determine how much liquid is lost, which will prove which combination of Pop and Mentos created the most successful reaction. After each reaction was carried out, the Diet Coke and Mint Mentos combination lost the most liquid, thus creating the biggest fountain of foam. From this evidence, we can conclude that the large porous surface of the Mint Mentos combined with the aspartame in Diet Coke, produces the most violent reaction. Keywords: Aspartame, Surface Area

In her study with her Physics class they used both Diet Coke and Mentos among other carbonated beverages and sugar containing products. The basis of their experiment was to determine what type of reaction was taking place in this explosive display. Different and similar methods were use to come to the conclusion of reaction type. As in our experiment the mass before and after the experiment was recorded in oder to determine which Pop and product mixture created the most explosive reaction. While testing the pH changes specifically in the Diet Coke and Mentos trial, it was determined that the reaction was not acid-base because there was little change in the pH. Because the presence of carbonic acid and carbon dioxide are already known in the Coke products, the equilibrium between these is merely disturbed by the introduction of Mentos. Differently, if the reaction was in fact acid-base as it was when baking soda was used; the acid would have been neutralized. The active ingredients in mainly the pop seem to play a large role in the reaction that occurs; Caffeine, aspartame and potassium benzoate all allow for the carbon dioxide bubbles to be produced. Aspartame, which is a type of sweetener, works better for the creatin of bubbles than drinks that are sweetened with corn syrup as well as the benzoate, the combination of the two creates a large reaction of bubbles and mass lost. On the other side of the spectrum, the physical makeup of the Mentos makes the reactions different. The difference between Fruit and Mint Mentos are the coating. While the Fruit Mentos are contained in a waxy candy coating that reveals rough patches, Mint Mentos are also covered in rough spots. These areas of roughness on the surface of the Mentos work as growth sites for crabon dioxide, or bubbles, to be formed. The more area there is for the growth of these bubbles, the more explosive the reaction will be. Along with the varying space for growth sites, the force in which the Mentos fall is a contributing factor. While each of the Mentos is dropped, they travel to the bottom of the bottle, on the way down, bubbles begin to form and rise to the top of the bottle. The Mentos that have more growth sites often have longer reaction times until completion. The results of our tests and the tests done by Coffey and her students were similar; however their discovery of the reaction type was significant to the explanation of our results.
