ABSTRACT:
A novelty device in the form of a color-changing amusement ball comprising a spherical body member, a transparent spherical cover concentrically surrounding the body member and spaced therefrom to define a spherical cavity, and a layer of liquid crystalline material disposed within the cavity. The liquid crystalline material is responsive to temperature changes and/or deformational stresses applied thereto so that the material changes color with a change in temperature to which the ball is exposed and/or on deformation of the ball which can be accomplished by impacting the ball against a hard surface.
