Quick Answer
The lava lamp was invented by British entrepreneur Edward Craven Walker, who launched it in 1963.
The Full Story
Edward Craven Walker was inspired after seeing a homemade liquid-filled egg timer in a pub in Dorset. He spent years developing a lamp in which heated wax rises and falls through a clear liquid. His company, Crestworth, launched the 'Astro' lamp in 1963. The lamp became an icon of 1960s and 1970s psychedelic style. Its successor company, Mathmos, still makes lava lamps in Poole, England.
Key Facts
1.A bulb at the base heats the wax, making it less dense so it rises.
2.As the wax cools at the top, it becomes denser and sinks.
3.Lava lamps usually take a while to warm up before the wax flows freely.
