This experiment creates a fountain of pop that can go as high as six feet!
DO THIS OUTSIDE! It will make great mess.
2-liter or 20 ounce bottle of not sugar free pop (the more pop, the higher the fountain.)
A roll of Mentos candy (other candy works okay, but Mentos work best for some reason.)
1. Get the Rollo’s ready. Take part of the wrapping off so that you can quickly put
them into the pop bottle.
2. Open the pop bottle.
3. As quickly as possible pour half the roll of Mentos into the pop.
4. Stand back!
