Flash flying saucer

A flash flying saucer adopts a method that two-way convex parts are arranged on the front face and the back face of a transparent soft plastic disc, twenty small bulbs or light-emitting diodes are installed on twenty outer rings and forty-five outer rings in total, two large button batteries are installed in the center of a five-star, and a parallel circuit is used for installation. And the arrangement carrier of the electronic components of the flashing flying saucer is formed. Thickness brought by two-way raising of the front face and the back face of the five-star center causes raising of acentral cylindrical space for installing a battery, raising of an outer ring, raising of a five-star outline and raising of a connecting line between the central cylindrical space and the five-star outline, and wiring and installation of a small bulb or a light emitting diode are facilitated. A switch is arranged on the side edge of the disc body of the transparent soft plastic disc on the outerside of the sealing cover,
