=Mentos and Soda= Problem: What happens when mint mentos are added into different types of soda?

Background:" Each Mentos candy has thousands of small pores on its surface which disrupt the polar attractions between water molecules, creating thousands of ideal nucleation sites for the gas molecules to congregate," (Mental Floss). When you combine Coke and Mentos a large amount of CO2 gas is subsequently released from the soda followed by foam erupting from the bottle. The mento is ideal for this reaction because it has many small pores on its surface, these pores catalyze the release of CO2. "MythBusters concluded that the potassium benzoate, aspartame, and CO 2 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," (Wikipedia). Diet Coke is always recognized as the only soda used in the experiment, but we want to try a variation of sodas. We are looking to see if a different soda will give a better reaction and thus a higher geyser. We will use diet Coke as a control group and use three other sodas, such as Mountain Dew, Sprite, Dr. Pepper, Pepsi, or Root Beer, as variable groups.

Hypothesis: If we drop mentos into a dark soda, it will rise higher than a lighter colored soda.

Materials: - 4 different types of soda. 2L bottles ($3 each) - 2 packs of mint mentos ($1 each) - Meter Stick

Methods: 1. Set up a 2L of soda with a meter stick behind it 2. Drop a mento into the open soda bottle 3. Record on slow motion camera 4. Record how high the soda sprays on each bottle (in meters)

Data:

Conclusion: From analyzing our data, we concluded that our hypothesis was correct. The dark or brown sodas went higher off of the ground when we put a mint Mentho in them.
