Fridge Rover is a magnet and wind-up vehicle all in one. Inside the clockwork mechanism is a coiled spring that is wound more tightly as you turn the handle. This stores energy in the spring (potential energy). When you let go, the spring uncoils, releasing the energy again, and making the wheels turn (kinetic energy). The wheels grip the surface because the magnet pulls the Fridge Rover firmly against the fridge.
