From the Rube Goldberg Contest at Purdue:
Inspired by cartoonist Rube Goldberg, college students nationwide compete to design a machine to complete a simple task using 20 or more steps.
The 2009 task was to replace an incandescent light bulb with a more energy-efficient, light-emitting design.
Check out our favorite entry, "Scene of the Crime," from the University of Illinois team. It won second place.
