Zero-Gravity Fridge Rover Magnet

Wind up the gears and watch the Zero-Gravity Fridge Rover Magnet defy gravity! See how it moves up the fridge surface, using the power of kinetic energy. It's an amazing science gadget!

Inside the Rover's clockwork mechanism is a coiled spring that winds 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.
