Abstract
An ornamental ball includes a spherical body consisting of two semi-spherical half bodies, and an inner ornamental member contained in the ball. The inner ornamental member is fixed inside the ball, having an axis shorter than the diameter of the ball and having two ends of the axis fixed at non-diametrical locations of an inner surface of the ball. Consequently, the ball rotates irregularly owning to the gravitational impact of the ornamental member.
