Rubber Band Powered Car C-28 Basic STEM Toy Kit Helicopter Get into the groove —After an a object is deformed by an external force, if the external force is removed, the force that the object exerts which returns it to its original shape is called "elasticity". Its direction is opposite to the direction of external force that caused the object to deform. We use the elasticity of the rubber band as a power source to allow the car to travel.
