Exploding Soap Bubbles: Hydrogen + Oxygen  
A series of three videos shows that as the ratio of oxygen to hydrogen in soap bubbles increases, the explosions that occur when the bubbles are ignited get louder. (The fact that with an excess of oxygen the explosions would become softer again is not shown.) Each video is repeated with no voice-over so that only the sounds of the explosions are heard. Five still images are provided to show the stoichiometry on the molecular scale. The videos are intended to be shown in order beginning with Hydrogen Alone and ending with hydrogen plus more oxygen.

Hydrogen + Chlorine Cannon  
When a corked test tube containing a mixture of hydrogen and chlorine is struck by light from a burning magnesium ribbon, the resulting explosion propels the cork out of the test tube.
