ABSTRACT:
One type of kaleidoscope has an object cell that contains a multitude of small objects immersed in a viscous liquid. By inverting the object cell, a user can enjoy a continuous ever-changing display of pleasing and colorful symmetrical images as the objects cascade through the viscous liquid under the influence of gravity. Eventually the objects settle to the top or bottom of the object cell as determined by their densities, and the viewer needs to invert the object cell again. It is desirable to prolong each cascade so as to reduce the frequency with which the object cell must be inverted. Several ways of accomplishing this are disclosed. The walls of the cell may converge and may be provided with bumps or other surface irregularities. The movement of the objects may be impeded by the provision of fixed obstacles within the object cell. In another approach, an upwelling and circulation of the viscous liquid is produced by a simple pump that is mobilized by inverting the object cell.
