  • Patent number: 3954269
    Abstract: This invention pertains to a generally ball shaped device having a hollow interior chamber with a relatively small weight such as a steel ball bearing in said chamber; the exterior surface of the device is provided with a plurality of numbers or other symbals spaced thereabout, preferably in a symmetrical relationship. The interior chamber provides a pocket diametrically opposite to each symbol whereby the ball shaped object, when thrown along any flat surface or into water, will always come to rest with one symbol positioned on the top thereof diametrically opposite to the pocket in which the interior weight settles due to gravity forces.
