The stronger hydrogen peroxide will produce a massive amount of foam in this experiment. The sodium iodide is a catalyst. This is something that has the ability to speed up a chemical reaction and makes the hydrogen peroxide break down very quickly. When the Mentos are dropped into the diet soda, it causes a chemical reaction. The reaction takes place so quickly because Mentos have very small pores on their surface. These help to cause the reaction with the CO2 to occur very fast.
1. Would this reaction be different with a different type of candy? Which ones would work the best? Why?
2. Would this reaction work the same with a different carbonated beverage? Why?
3. Can this reaction be done if a beverage was old and was less carbonated?
