Disc amusement device

Abstract

A disc amusement device may include a central body and a peripheral body. The central body may have an upper convex surface that may be circular shaped and a lower convex surface that may be circular shaped, and the upper convex surface may be opposingly positioned relative to the lower convex surface. The peripheral body may have an annular shape, and the peripheral body may be coupled to the central body so that the peripheral body may be concentric with the central body. The peripheral body may include an interior convex wall and an exterior convex wall. The interior convex wall may be coupled to the central body, and the exterior convex wall may be distal to the central body. An upper valley may be formed between the interior convex wall and the upper convex surface, and a lower valley may be formed between the interior convex wall and the lower convex surface.
