2Is Mentos the only candy that makes Diet Coke erupt? My QuestionIs Mentos the only candy that makes Diet Coke erupt?
3ResearchThe reaction with the Mentos and Diet Coke is not a chemical reaction but a physical reaction. This means that nothing new is happening.The reaction occurs when the carbon dioxide gets trapped in nucleation sites(bumps on Mentos surface).This reaction multiplies and the geyser is formed.
4My HypothesisMy hypothesis is that Mentos is not going to be the only one that works because it is a physical reaction, and other candies may have this same physical feature as the Mentos.
5The ExperimentI tested out five different candies in this experiment including the Mentos.I used a PowerAde bottle as a tube and I dropped all five candies into the diet coke and observed how high the geyser went on each.MaterialsLemonheadsSweetartsSweetart ShockersSour SkittlesMentosSix 2-liter Diet Coke bottlesPowerAde BottleSpaceControls and VariablesControl=Diet CokeIndependent Variable= CandyDependent Variable= Size of Geyser

7My ConclusionMy conclusion is that my hypothesis is somewhat correct. With their being a reaction with all of the candies, but with Mentos being a true eruption.
