The most complex Rube Goldberg machine in the world

Purdue’s Society of Professional Engineers and the Society of Hispanic Professional Engineers have created the world’s most complex Rube Goldberg machine. The 300-step machine has set a new record for the largest functioning Rube Goldberg machine, according to the Guinness Book of World Records.

A Rube Goldberg machine is a deliberately over-engineered device that performs a simple task in a complex fashion. In this case, the machine blows up a balloon and pops it.

The team spent 5,000 hours building the contraption. Last year, the same group created a machine that had 244 steps.

The contest dates back to 1949, when it started as a competition between two Purdue University fraternities. That contest lasted until 1955. It was revived in 1983, and the first national contest was held in 1988. Sponsors for this year’s national competition were Alcoa, Lockheed Martin, Priio, Rockwell Collins, and the Purdue Colleges of Engineering and Technology and the School of Mechanical Engineering.
