Rube Goldberg: 125-step flashlight battery changer

Robert sez, "Inspired by cartoonist Rube Goldberg, college students nationwide compete to design a machine that uses the most complex process to complete a simple task – put a stamp on an envelope, screw in a light bulb, make a cup of coffee – in 20 or more steps.

"This year the contest involved changing the two batteries in a torch. The winning team did it in 125 steps."
