Abstract
A novelty lamp which comprises a transparent container with a top surface, a bottom surface, an outer portion, and an inner portion. The inner portion extends upwardly from the bottom surface of the container and defines a hollow area. The bottom surface of the container is mounted in a base member. Two substances are received in the container. One of the substances has a higher relative density at room temperature and is immiscible with the other substance. Upon application of heat, which is supplied by a light bulb mounted within the base member, globules of the substance with the initially higher relative density become less dense, rise in the other substance and flow around the outer and inner portions of the container. As the globules rise toward the top surface of the container they cool, become more dense and drop back down toward the bottom surface of the container.
