ABSTRACT:
An apparatus for generating a deep U-shaped vortex, with the vortex being of sufficient height to include a relatively large air well in its center. The apparatus may be used as an amusement park ride, wherein it comprises an observation platform, a large vessel partially filled with liquid, and an impeller to rotate the liquid within the vessel and thereby create a vortex of liquid within the vessel. When the vortex is created, an air well develops in the center of the vessel, with the air well being of sufficient size to allow the entry of the observation platform therein, with the observation platform being surrounded below and at its sides by the rotating liquid, but without coming into contact with the rotating liquid.
