Don’t get too excited about stumbling across another video of a dazzlingly fast-moving, complicated Rube Goldberg machine. While this creation certainly has some clever mechanisms, it’s also billed as the world’s slowest—and that’s actually selling it short.
Designed and built by YouTuber Bob Partington, watching a golf ball get from one end of this maze to the other is an endurance challenge that’s really only made tolerable through the magic of video and time-lapse photography.
The obstacles include waiting for everything from molasses to pour, to a turtle to meander a couple of feet, to simple grass growing that helps push the golf ball along. In real-time, it required a total of six excruciating weeks for this Rube Goldberg machine to deliver the golf ball to its final destination—so you’ll probably just want to stick with this three-minute condensed version.
