Diet Coke and Mentos Reactions

Abstract- Which Soda Will Sprout The Highest With Mentos?

The experiment I chose was “Which soda will sprout the highest with Mentos?”. The reason I chose this topic was because everyone knows that the chemical reaction with coke and mentos is, but what about other sodas? I thought that the Coke would sprout the highest because the reaction I’ve seen is like no other!

This experiment only took about 3 steps. First, I had to make sure I had all of my materials and set up something to measure with(feet or inches). I wasn´t sure on how i´d collect data because the explosion would be too fast for me to really tell how high. I ended up using a camara to take videos, and it helped so much. Once that is done you open up your soda and carefully drop 3 Mentos. I record the whole reaction to collect data. I repeated this procedure 2 more times after the first.

After collecting data, the results were shocking! They were a lot lower than I expected. Coke had an average of 4 in., Sprite had an average of 2.8 in., Fanta had an average of 0.6 in., and Birch Beer averaged at 1in. Fanta obviously didn’t do too well!

I predicted that Coke would have the highest results, and my hypothesis was correct. Also, Sprite had a pretty close 2nd place! I thought that the results were low, so I think that it would be more accurate/better with 2 liter bottles because there will be more soda. I could also make sure that each soda is exactly the same temperature. This project has taught me that Birch Beer isn’t as powerful as i believed. Also, that sometimes things are unexpected.
