So little alcohol, so much energy. 5mL of methanol or ethanol is ignited in a 5 gallon water bottle. The alcohol burns at such a high rate itcreates a rocket engine effect. If the mixture is just right, it can knock ceiling tiles off. It looks really amazing atnight. After the burn, the bottle is capped and Charles Law is 8demonstrated.
