Adam Savage builds a Kendama

Adam Savage, who you probably know from the the old Discovery Channel show MythBusters and more recently the hit YouTube channel Tested teams up with Michael Steven's of Vsauce for a special one-day build in Adam's workshop.

"Michael has recently taken up playing the Kendama, a Japanese cup and ball toy, and Adam helps make one from scratch that helps optimize his play. This build engrosses both into topics of machining, knot tying, and geometric conundrums."
