Ball centrifuge for use as toy, advertising or therapy; has balls moved by inclination, rotation or oscillatory movement of tubular, cylindrical, spherical or egg-shaped hollow body or gravity

摘要

The ball centrifuge has transparent hollow bodies (1) that interact with balls (3,3a) to produce advertising media, toys or therapeutic devices. Inclination, rotation or oscillatory movement of a tubular, cylindrical, spherical or egg-shaped hollow body of two identical or different halves clipped together sets balls in motion. Alternatively, the balls are moved by gravity. The base parts may have mirrors inserted in recesses to produce optical effects, or be covered with holograms.
