  • Patent number: 4747798
    Abstract: A flying dish having a convex center portion surrounded by a concave ring portion. The convex center portion has the form of the pistils of a flower. The concave ring portion supports petals of a flower. The concave ring portion contains respective pivot axles for the flower petals. Each pivot axle is provided with a coiled spring extending between the inner wall of the concave ring portion and a slot on the back of a flower petal. Each flower petal is provided with a small whistle. When the rotational speed of the flying dish reaches a predetermined level, the flower petals open under centrifugal force and begin whistling due to the air stream. When the speed of the flying dish slows, the flower petals gradually close and the whistling disappears.
