The History Of The World in 244 Steps

On YouTube:

Immediately after the 2011 national Rube Goldberg Machine Contest, a machine built by the Purdue’s Society of Professional Engineers team completed a flawless run of 244 steps setting a world record now featured online by the World Records Academy.

It doesn’t have the poetry of other Goldberg pieces I’ve seen (like OK Go’s video, or that Honda commercial), but impressive nonetheless.
