Contact juggling is like what those Fushigi balls are supposed to have you do. Or like The Goblin King does in Labyrinth. It's certainly an art form that takes patience and practice. Then, there's this guy. Akihiri Yanai makes it look like it's no big deal contact juggle. As one of the YouTube comments mentions, "at some points it doesn't even look real."

And now you have your task. Run, don't walk, to get your self some of those Fushigi balls and start practicing!
