Abstract
Hand-holdable toy light tube comprising a handle, a light source and a tube of color shifting film. The light source is preferably disposed within an end of the handle. The tube of color shifting film extends from the end of the handle. During use, light from the light source interacts with the tube of color shifting film, producing a brilliant colored effect. Movement of the handle and thus of the tube of color shifting film produces multiple colors.
