300 step Rube Goldberg device smashes world record!

The Purdue Society of Professional Engineers team smashed its own Guinness world record for largest Rube Goldberg machine with a 300-step behemoth that flawlessly accomplished the simple task of blowing up and popping a balloon.

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.
