Abstract
Abstract The present invention is an article of manufacture comprising an inner surface, an outer, generally visually transparent surface, and a generally annular space between and defined by the inner and outer surfaces. The annular space contains a liquid. One or more generally flat disks are provided within the annular space, and the disk or disks floats upon the liquid. A plurality of fins within the annular space imparts turbulence to the liquid and propels the disks as the article is rotated about its axis.
