A coin drops into a container in a complex series of chain reaction steps to perform a simple task. The first lever is pulled and activates a second lever, which in turn activates a third lever pulling the magnet away from the steel ball. The steel ball rolls down the ramp tipping the teeter-totter and knocking the coin onto the exposed wires. A buzzer is then activated and, as a result, the vibration knocks the coin into the cup.
