MilesMagic Micro Psychic Nut Off Bolt Screw Gimmick - Magic Trick

Magician first demonstrates a bolt and a nut to audiences. Then he randomly choose one of them, and asks the person to fasten the nut onto the bolt a few rounds. The magician then holds the bolt by two fingers wearing short sleeves, and it's time for the magic to happen. The magician puts a spell on the device and the nut gradually moves on its own, no interference by the magician, then spins off from the bolt.

The magician passes the separate pieces to the audience for inspection. They look just like any ordinary bolt and nut. You can perform the trick in any condition without practicing any skills.
