Woflgang and Allen quickly and efficiently prepare the Mousetrap Fission demo for Robert Kirshner's The Energetic Universe course on February 26, 2015. The demo consists of 110 mousetraps armed with ping-pong balls; the demonstrator drops a single ball from above to initiate an event similar to a chain reaction.
