A flying saucer-shape gyroscope monocycle that stands by its own gyroscope action. The device is composed of a transparent plastic-made upper dish-rotor and a lower dish body. A small D.C. motor is installed in a central hole of the lower dish body and is powered by two small batteries. The shaft of the motor is fitted tightly with the upper rotor so as to drive the rotor. High speed rotation of the upper rotor causes slits on the surface to buzz continuously. The unbalanced force of the high speed rotating upper rotor causes the whole gyroscope to vibrate and thus a vibrating switch disposed in the lower dish body contacts intermittently to cause a bulb connected thereto to flash intermittently. The flashing is visible through the transparent upper rotor and a side window in the lower dish body. Satellite bodies disposed along a circular flange on the lower body rotate counterclockwise by the reaction to the motor driving torque.
