There's something that's oddly hypnotic about watching this
hand-cranked machine slice, drop and catch these small spherical
rare earth magnets one at a time. The little 5mm ball magnets
start out as a connected string, and are continuously fed
through the contraption in a loop. As the video goes on, you get
to see views from different angles as the balls are tossed
around and the machine hands off each tiny silver globule like
it's playing catch with itself.  The apparatus is entirely hand-
built, created by inventor Dave Johnson for his father-in-law's
75th birthday. Pretty neat stuff. I don't know how this thing
wouldn't score any points in ol' daddy-in-law's eyes. [Laughing
