This is Ben's version of the classic Martin Gardner's Deck Twist. But instead of a deck, you'll only need a willing spectator's wrist for this. You'll wrap the band around their wrist a couple of times, be careful of getting it too snug. Then, after three slight tugs on the band, it'll curiously unwrap itself. You'll be left with the now free band in your hand and the spectator's wrist naked once again.
