Generate hydrogen gas using aluminum metal and sodium hydroxide and ignite. Something interesting will happen! When an empty, bottomless soda bottle is filled with hydrogen and the gas ignited, the hydrogen will burn with the flame decreasing in size. After awhile, the reaction will whistle. Suddenly, the hydrogen will explode with water vapor condensing on the inside surface of the bottle.
