The Minty Cola Fountain
Using a bottle of fizzy cola and a packet of mints, Professor Hal Sosabowski performs a dramatic, demonstration showing carbon dioxide coming out of solution at immense speed in this Teachers TV video. When sparkling drinks are made, carbon dioxide is forced into solution under pressure and the bottle is sealed. The resulting eruption when mints are added shows how nucleation sites can cause a reaction to occur spontaneously.
