A wire loop game, or buzz wire, is a game which involves guiding a metal loop (a 'probe') along a serpentine length of wire without touching the loop to the wire. The loop and wire are connected to a power source in such a way that, if they touch, they form a closed electric circuit.

In this game, you will guide a metal wand along the length of a bent wire without touching the wire. The wand, the wire, and a buzzer are connected to a battery. The minute the wand touches the wire, the circuit is closed, causing the buzzer to make a loud buzzing noise.
