Rube Goldberg machines turn even the most basic tasks—like zipping a zipper—into complicated, overwrought feats of physics. But at least they usually do them fairly quickly. Not so with builder Bob Partington’s Rube Slowberg. 

Showcased on the YouTube show Field Day, Partington describes his invention as the world’s slowest Rube Goldberg machine. To allow this machine to complete its task—getting a golf ball into a hole—requires waiting for molasses to drip slowly out of a jug, a turtle to amble across the course, popsicles to melt, and more. At one point, the ball is rolled forward by the motion of grass growing. Yes, you have to wait for the grass to grow. The total time elapsed between when Partington hits his ball and it arrives at the hole? More than six weeks. Luckily, the video is a timelapse.
