ABSTRACT:
Described herein is a novel optical toy of the kaleidoscope type. The article is comprised of a cylindrical tube having a mirrored inner surface. This tube contains a transparent sphere which is gravitationally rollable through the interior of the tube. The sphere is retained within the tube by means of a ring positioned about each end of the tube. The ring has an inner diameter slightly smaller than the diameter of the sphere thereby preventing the sphere from passing from the tube. Positioned on the outer end of the tube is a prism or other suitable article useful in refracting light. This may be spaced a short distance from the outer end of the tube by means of a clear tubular attachment and it breaks up white light into its various components and reflects the different color light into the tube where it is reflected off the mirrored inner surface and passes through the transparent sphere producing various eye-pleasing color designs on the mirrored inner surface.
