Invented by Edward Craven Walker, this novelty lighting instrument featured a glass bottle full of wax and oil with a coil in the metal base. When the lamp was turned on, the coil would heat up and globs of wax would bubble around in the oil, producing a "lava" effect. Some claimed the lava lamp was meant to simulate the hallucinogenic visuals from the drugs that were becoming so popular.
