ABSTRACT:
A display device consisting of a sealed chamber defined by two closely spaced panes or plates of a transparent or translucent material. Liquids of different specific gravities and selected viscosities are located in the chamber. In operation, the device is inverted and the liquid of the heavier specific gravity flows through the liquid of the lighter specific gravity in distinct, spaced apart beads or droplets under the influence of gravity. The downward flow of the heavier liquid causes the upward displacement of the lighter liquid. A series of obstructions of various shapes and geometric configurations are interposed in the flow path of the heavier liquid to change its flow path and create the visual display.
