To make a Diet Coke Geyser all you need is mint Mentos and Diet Coke in a plastic bottle.
All you do is open the lid to the diet Coke and drop the Mentos in. The second the candy hits the Coke a geyser will shoot several feet in the air. If you want a taller explosion, then use a 2 liter bottle of soda. Amazing and fun!
I did not know Diet Coke had that much power. Two young men fueled a car for several feet with just Diet Coke and Mentos.
