ABSTRACT:
Rounded moveable members such as a ball are directed in two established and independent lengths of transparent tubing which are arranged within a transparent sphere. The rounded moveable members such as a ball have a diameter smaller than the inside diameter of the transparent tubing thus the rounded moveable members such as a ball follow a path that gives a spinning motion. The spinning motion for the first path will be directed by the tubing secured to the inside of the transparent sphere from top to bottom. Thus the first path follows the curvature of the sphere from top to bottom. The second path is directed by the transparent tubing arranged in a cylindrical spiral about the center of the sphere which allows the rounded moveable member such as a ball to follow a cylindrical spiral path from top to bottom of the sphere. The length of tubing about the center of the sphere that is arranged in a cylindrical spiral is supported by a transparent cylinder that is secured by the transparent sphere.
