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.
