The Geyser Tube experiment is a new version of a classic experiment - mixing Mentos® with cola for an amazing physical reaction.

With microscopic layers of liquid sugar on the surface, the Mentos® attract the carbon dioxide of the cola, creating a reaction called nucleation that results in cola rushing out of the bottle.

The tube dispenser enables kids to drop the desired number of Mentos® mints into the cola bottle (not included) from a safe distance before the reaction happens. When the mint is loaded, pull the pin, stand back and watch as the cola produces a sensational 25ft high jet.
