Ornamental or amusement device

Claim 1

An ornamental or amusement device, comprising: a housing formed with a closed internal chamber adapted to extend in the vertical direction when the housing is supported in an upright position; at least one side of said housing being transparent to permit viewing said chamber; said chamber being filled with a transparent liquid; a body disposed within said chamber and having the geometrical configuration of two inter-penetrating tetrahedra including eight apices and presenting the appearance of a six-pointed star when viewed along the axis of any one of said eight apices; the housing at one end of said chamber being formed with a recess corresponding to the shape of said apices; said body having a density different from that of said liquid such that inverting the housing from its upright position causes the body to move through said liquid away from said one end of the chamber to the opposite end, and then returning the housing to its upright position causes the body to move through said liquid back towards said one end of the chamber until one of the apices of said body is received within said recess formed in said one end of the chamber for orienting the body with respect to the transparent side of said housing; said chamber being of larger cross-sectional dimensions and height than the largest dimension of the geometric body so as to permit the geometric body to tumble when moving away from said one end of the chamber towards the opposite end.
