Rube Goldberg reality show casting call

The Discovery Channel is casting for a reality show called "Super Rubes," in which the contestants will build elaborate Rube Goldberg machines.
Super Rubes is a weekly one-hour show that follows a band of talented creators as they design, build, and set off a massive Chain Reaction Machine in front of a cheering crowd. The point of a Chain Reaction Machine is to do something very simple, like turn on a light bulb, using as many steps as possible. This is an opportunity for engineers to let their creative hair down and have some fun building a giant Chain Reaction Machine. Our team will take on impossible challenges (i.e. "Can you crack an egg with a human hair?") in a race against the clock.
