The Hand Buzzer produces a startling but harmless buzzing sensation. You slip the ring of the hand buzzer over your finger and conceal the device in your hand. Wind it up in a clockwise direction and you're ready for action.

Shake hands with the victim and watch their reaction as they try to figure out what's going on.

Another way to use the hand buzzer is to ask somebody what kind of bug is red and blue with green wings. When they ask why, tell them that they have one on them and then press the buzzer against their back.
