Money Eating Robot
Ages: 8+
The Money Bank Robot is hungry for money! Just place a coin on the coin tray and - Gulp! - The robot swallows the coin into its mouth! The Money Bank Robot is composed of two series of circuits controlled by a knife switch. The reason why the robot can open and close its mouth is the conductivity property of conductors. Conductivity is a property that allows electricity to flow through a material. Coins are conductive materials. When the coin touches the two metal pieces on coin tray, the circuits are connected, driving the motor to rotate.
