Flying Top

The Flying Top is essentially a top which is spun by pulling a rip-chord attached to its spinner. Once the top is spun, the mechanism creates such a high torque that the top actually hovers up instead of falling. This is achieved by making the top very light( yet stable) and by the three wing-like features on its sides which produce lift.
