Patent ID: 8479421

Claim:
A circulating fluid amusement device comprising: a transparent, liquid filled enclosure, the enclosure having a three-dimensional geometrical shape, the three-dimensional geometrical shape having at least a first surface region and a second surface region such that when the three-dimensional geometrical shape is oriented in a first orientation the first surface region is positioned below the second surface region and when the three-dimensional geometrical shape is oriented in a second orientation the first surface region is positioned above the second surface region, the enclosure housing a stirring impeller and a plurality of particles, wherein the stirring impeller has magnetic properties and is freely moveable within said enclosure, such that the stirring impeller tends to move towards the surface which is closure to a defined bottom of the enclosure; a base support configured to removable support the geometrical shaped enclosure in more than one orientation, such that when the enclosure is positioned in the first orientation on said base support, the enclosure is removable from and is returnable to said base support in the second orientation; and a magnetic stirring system positioned within the base support, the magnetic stirring system having a rotating rotor powered by a stirring motor, the rotating rotor having magnetic properties such that when the enclosure is positioned on said base support in one orientation, of the more than one orientations, the stirring impeller within the enclosure moves towards the bottom of the enclosure closer to the first or second surface regions of the enclosure that is oriented below the other surface region and becomes magnetically coupled to said rotating rotor, wherein when the device is activated, the rotating rotor rotates the stirring impeller to move the plurality of particles.
