The history of the world in 244 steps!
From the YouTube description:
The 2011 Purdue University Rube Goldberg machine shattered the world record for most steps ever successfully completed by such a machine. In 244 steps the “Time Machine” traces the history of the world from Big Bang to the Apocalypse before accomplishing the assigned everyday task of watering a flower. The record has been sanctioned by the Guinness Book of World Records and the World Records Academy.
