To provide a flying top form toy equipped with a flat surface body which at least has an area in the vicinity of the gravity center of the toy, and at least one planar extension having a terminal end.

A maximum distance (r) between the peripheral edge rim and the center of gravity, the mass (m) and/or the mass of an inertia (θ) of the flat surface body are defined. Therefore, this toy is started by the following method. a) The flat surface body is arranged in the vicinity of the gravity center of the toy, and on a convex surface. b) By flipping or jerking with a finger in a horizontal and tangential direction against the terminal end of the extension, a high speed rotating motion ω (ω≥300 rpm) can be imparted. At the same time, a low force VT (VT<ω*r) in the lateral direction alone is received. c) Therefore, the stabilization of the spinning under a horizontal state is ensured, and an air cushion to support the flat surface body during a flight is formed.
