Abstract: An oscillating wave cell is disclosed. The oscillating wave cell comprises a substantially transparent, fluid vessel having a generally upper surface, a generally lower surface and transparent end caps. The wave cell contains first and second immiscible fluids of different colors, such as primarily a light mineral spirits and water. An air trap is provided which extends downwardly from the lower surface of the vessel. The air trap includes a partition defining a first trap chamber and a second trap chamber. The air trap further includes a plurality of passages extending between the vessel and the first trap chamber for permitting fluid flow therebetween. The partition extends downwardly from the lower vessel surface and includes a slot disposed away from the lower surface for permitting fluid flow between the first trap chamber and the second trap chamber. A base having an upwardly extending rocker mechanism including a cradle concealingly receives the air trap and supports the vessel.
