UltraCinese - Pk bolt &møtrik

Ultracinese may be one of THE most amazing PK effects ever. Imagine you pick up a nut and bolt (both may be borrowed), thread the nut on the bolt, and upon your command the nut slowly starts threading itself off of the bolt as if caused by some ghostly action. You can reverse directions upon your command and the nut can wind back up on the bolt. You immediately give the nut and bolt (no switching) to the spectator to keep as a souvenir. Now get this... no thread, no magnets, no reels, no rubberbands, nothing attached to the nut or bolt, nothing hidden in your hand, no switching, no kidding. Sounds to good to be true, sounds impossible, sounds like hype?
