4M KidzLabs Zero Gravity Fridge Rover!
Wind up the rover and watch it defy gravity as it rolls across any magnetic surface, flat or rocky. See how it moves up the fridge surface, defying the force of gravity. It is an amazing science gadget.
How it works?
The Fridge Rover combines a magnet and a wind-up vehicle. Inside the clockwork mechanism, there is a coiled spring that winds up lightly as you turn the crank. This stores energy in the spring. When you let go, the spring uncoils, releasing the stored energy and turning the wheels. The wheels can grip the surface of the fridge without falling because the magnet inside holds the Fridge Rover firmly against the fridge.
