ABSTRACT:
An improved liquid motion lamp includes a second heat source to reduce warm-up time and a removable base cover to simplify changing a first heat source. The first heat source is preferably a light bulb residing in the base of the lamp, which light bulb provides both heat to cause motion of liquids within the lamp, and light to enhance a viewing effect. The sliding cover is preferably an open ended cylinder which slides upwards to provide access to the light bulb. The liquids comprises a first liquid which is a solid at room temperature and which is preferably paraffin based, and a second liquid which is preferably water. The first liquid may be empirically determined by mixing trial batches of paraffin and chlorinated paraffin to determine the correct ratio for a given lot of paraffins. The first liquid may be prepared, and shipped with the lamp in a solid phase. The second liquid may be added at the lamp's final destination.
