HOW it works: There is a tiny integrated circuit (IC) inside the unit magic circuit. The ic detects when a conductive medium, such as the line of the pencil, connects the two terminals, creating a closed circuit. The line of the pencil contains graphite, which is composed of carbon and conducts electricit very well. When the rings reach the two dots at each end of a line on the card circuit, the circuit is completed, activating the buzzer and the light bulb.
