Purdue University's engineering students have outdone themselves with this world-record-setting Rube Goldberg machine, which takes 300 increasingly quixotic steps to blow up (and then pop) a balloon.

Congratulations members of the Purdue University Society of Professional Engineers! You've made something both amazing and utterly useless, which makes you not only experts in over-engineering, but also bonafide Internet stars.
