<p>A wheel-shaped top with magnetic spindles projecting from the body. A circular disk with a beaded rim is mounted on each end of a shaft; the rims of the disks forming a two-rail track encircling the shaft. A handle has two legs attached to opposite ends of the shaft. The spindles are magnetically attached to the two-rail track. The top orbits around the track in response to hand manipulation of the handle; the top is launched from the track when the orbital speed is sufficient to centrifugally separate the spindles from the track to spin on a surface, and the top can be magnetically retrieved, while spinning, by engagement of the spindles with the shaft or with one or both of the disks. In an alternate embodiment, the top includes a simulating feature, such as a continuous or blinking light, a sound, or the like configured to activate when the top is rotated.</p> |
