1. A novelty article comprising:
- a handle including an end;
a plurality of sections of color shifting film extending from said end; and
a light source connected to said handle, wherein when activated, said light source illuminates at least a portion of said plurality of sections of color shifting film, wherein said color shifting film comprises alternating layers of at least a first and second polymeric material, wherein at least one of said first and second polymeric materials is birefringent, wherein the difference in indices of refraction of said first and second polymeric materials for visible light polarized along first and second axes in the plane of said layers is at least about 0.05, and wherein the difference in indices of refraction of said first and second polymeric materials for visible light polarized along a third axis mutually orthogonal to said first and second axes is less than about 0.05.

Abstract
Hand-holdable novelty article comprising a handle, a light source and a plurality of sections of color shifting film. The light source is preferably disposed within an end of the handle. The plurality of sections of color shifting film extend from the end of the handle. During use, light from the light source interacts with the plurality of strands of color shifting film, producing a brilliant colored effect. Movement of the plurality of sections of color shifting film produces multiple colors.
