World's biggest lava lamp unveiled on South Bank. The biggest lava lamp in the world has gone on display on the South Bank. The 200-litre version was created to mark the 50th anniversary of the company that manufacturers them. Cressida Grainger, the Managing Director of Mathmos, says the super-size lamp will go on display as part of the London Design Festival.
Lava Lites are lamps that were invented by an English man named Craven Walker in 1964. They are basically tall thin glass jars filled with liquid and a special kind of colored wax, set on top of a base with a light bulb. When the bulb is turned on, the lamp glows, the liquid heats up, and the wax begins to melt. Blobs of wax rise to the top of the lamp, then cool and sink back down--over and over again.
