This exciting demonstration is a combustion reaction where a mixture of alcohol and air in a large bottle is ignited. Includes kit list and safety instructions.

The experiment demonstrates dramatically just how much chemical energy is released from such a small quantity of fuel. A single demonstration will take 5–10 minutes. Repeat demonstrations will require either the drying out of the reaction vessel used for the first demonstration or spare dry reaction vessels.
