Rube Goldberg machines, those kooky machines that perform simple tasks with convoluted methods, are generally a thing of marvel, especially when said Rube Goldberg machine is the winner of the 2014 annual contest among college students. Luckily, that impossible contraption, which was built by a team of students from Purdue University, appeared last night on Jimmy Kimmel. 

A little background: Rube Goldberg was a cartoonist and mad tinkerer who conceptualized crazily-inefficient machines in the ‘30s. But this is the Internet so of course you already know that.

Watch in childlike amazement as this machine goes through an elaborate process to zip a man’s zipper.
