HOW IT WORKS: The tip of the stick consists of a central stud with a spring around it. The battery, switch, buzzer, nail and wire are connected to form an electrical circuit. The wand acts as an extra circuit breaker. When you touch the ends of the track with the stick, the spring bends and hits the nail. This completes the circuit, causing energy to flow through the buzzer, activating it.
