Friday Fun: Rube Goldberg edition

Rube Goldberg Machines are always fun, and I saw a video for this one on a recent BoingBoing post. What caught may attention, of course, is the role a chess set played in the whole thing.

The video is pretty good, but there are quite a few jump cuts so I figure they weren't quite able to make the whole thing work in one go. No problem, it's still very cool.
