Small, pea-sized balls of aluminum foil to cover the bottom of your flask. Cover the foil balls with a teaspoon of Red-Devil Lye (or the equivalent) ...Pre-stretch the balloon, (Blow it up completely first, then let the air out)...Cover the mixture with water and quickly place the balloon over the flask. It will fill with the reaction and you will have enough to rise the balloon to the ceiling.

Notes:The gas is highly explosive. The flask will reach a high temperature during the reaction.
