Diet Coke and Mentos. It has to be Diet though.

You only need a 2L bottle of the Diet, and you need to throw some mentos in there, bottle it up, and then drill a hole through the top of the cap, and BOOM, you get a big chemical reaction

:)

It's a classic project, but it's also fun to do with friends in your free time.
