Video: Rube Goldberg Machine Record

The Purdue Society of Professional Engineers team smashed its own Guinness world record for the world's largest Rube Goldberg machine with a 300-step behemoth that flawlessly accomplished the simple task of blowing up and popping a balloon. The machine debuted at the 25th annual Rube Goldberg Machine Contest at Purdue University. The team’s entry in last year’s contest, a 244 step machine, was the previous world record holder.

The team spent more than 5,000 hours constructing the machine that accomplished every task ever assigned in the competition's 25-year history, including peeling an apple, juicing an orange, toasting bread, making a hamburger, changing a light bulb, loading a CD and sharpening a pencil.
