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.
