Everybody knows that Diet Coke + Mentos = geysers of carbonated awesomeness. But though it’s the most famous reactive liquid, Diet Coke isn’t the only drink that will activate on contact with Mentos and make a mess of your kitchen!

If you’re feeling especially Mythbuster-y, tape several pieces of poster board together, mark off heights, and see which beverage creates the greatest geyser. (Hint: Don’t skimp on the diet root beer.)
