Geyser Tube

If you love fun science experiments, you will get a blast out of the Geyser Tube. All you need is the Tube, a roll of Mentos candy and a liter bottle of soda. Assmble everything according to the instruction booklet and then stand back. Because before you know it, the chemical reaction within the bottle between the candy and the pop will send a foamy geyser shooting up to 25 feet into the air. Oh, yes. You don't want to try this inside. This is definitely an outside toy.

The Geyser Tube is loads of stilly sticky foaming fun that will have you laughing every time you set it off.
