Abstract
A toy vehicle has a curved cam surface on the upper surface of its chassis, with a forward point on a tangent that is relatively close to the center of mass of the vehicle, and a rearward point on a tangent that is relatively far from the center of mass. The vehicle includes a breaking mechanism that can be used to start the vehicle rotating forwardly. As the vehicle rotates, the point of contact between the vehicle and the supporting surface moves from the front wheels to a leading edge and subsequently to the cam surface. As the vehicle rotates with the cam surface in contact with the supporting surface, the center of mass of the vehicle is forced upwardly, providing sufficient momentum to propel the vehicle into the air.
