    摘要: A ball whirling toy having an orbital track with a concave/convex cross-section, the concave side of which faces inwardly toward the center of the track circumscribing the orbital track. A handling arrangement is secured to or part of the orbital track whereby, upon insertion of a ball within the track, and movement of track by the handling arrangement, the ball will be caused to move around the inside of the track. "Track" means any continuous path which can withstand centrifugal force caused by a motion of a ball around this path.
