- The Lava Lamp was invented in 1963 by Edward Craven Walker, and produced in Poole, UK by Mathmos (known as Crestworth until 1992) - the company that he founded. Many other companies worldwide now produce their own versions, but the Mathmos types are the originals.
A 40 Watt incandescent reflector golfball lamp in the base provides the illumination, along with the necessary heat that is required to liquefy the wax compound that is positioned at the bottom of the Lava Lamp bottle, within a coloured oil-based liquid. Notice that the wax forms something resembling a stalacmite as it warms up. Once the wax is liquefied, its lower density causes it to rise towards the top of the bottle in random blob shapes through convection; however, once at the top, the wax cools, and the density increases, causing it to return to the bottom, and the cycle repeats constantly until the lamp is extinguished, when the wax then cools, and solidifies at the bottom of the bottle again.
This particular example uses a bottle containing yellow oil and red wax, but there are many other combinations.
