ABSTRACT:
An ornamental lamp employs one or more upward extending transparent tubes containing an electrically non-conductive liquid under a partial vacuum. A heater at the lower end of each tube causes bubbles to form and to pass through a restriction and to ascend in the liquid. A series of electric lamps are spaced at intervals within the tube above the restriction. The lamps supply additional heat as the bubbles ascend to prevent condensation of the bubbles. The lamps also illuminate the bubbles. A pleasing twinkling effect is produced as each bubble passes one of the lamps.
