1 The Mentos and Diet Coke Experience has become quite popular all around the United States. When Mentos are dropped in Diet Coke, a huge eruption occurs. The main idea of this experience is to determine what causes the interesting reaction. There are many different theories floating around the internet, however; only one can be correct. This lab requires performing the Mentos and Diet Coke experiment numerous times, changing a variable. The variable that is going to be tested and changed is the substance Gum Arabic- an ingredient in the Mentos. The ingredient Gum Arabic reacts with the carbonation of the soda – making the huge eruption.

4 Abstract Our goal for the experiment was to find if the ingredient Gum Arabic, found in Mentos candy, caused the eruption when Mentos were dropped into a bottle of Diet Coke. Our hypothesis was that candies with gum arabic would have a greater reaction than those that did not. We tested this by dropping Mentos, Tic-Tacs, SweeTarts, and Kit-Kats into 2-liter bottles of diet coke, and measuring how much was left in the bottle when the reaction was done. Our hypothesis was proved incorrect by our experiment, because the second most-reactive candy was SweeTarts, which does not contain Gum Arabic.

5 Conclusion After doing the experiment, it was decided that the hypothesis was to be rejected. The hypothesis stated that the gum Arabic from the Mentos, and the carbonation from the Diet Coke created the reaction. However, two of the four candies used in the experiment did not contain gum Arabic, and they had extreme reactions. For instance, the Sweetarts (containing no gum Arabic) and Diet Coke mixture had the highest fizz geyser and only had 32 oz. of the solution left after the reaction. Obviously, this proved our hypothesis wrong. From this experiment, the group learned that this reaction is not a chemical, but a physical reaction. After this information was obtained, the group discovered that it cannot be the gum Arabic causing the reaction because all the candies created fizz and geysers. This showed that Mentos are not the only candy that can react with the Diet Coke. The experiment showed the group that candy and Diet Coke can potentially be dangerous. If someone takes a sip of Diet Coke directly after putting a piece of candy in their mouth, the reaction could occur inside their mouth. Aside from that, the errors in the experiment should be discussed. One possible error that was made was when the Tic-Tacs were dropped in the funnel, not all of them went through. This could have affected the results of the experiment. So, if the experiment was done again, the size of the funnel should be modified. Overall, the experiment went very smoothly and the results were quite surprising.
