KUSA - The lava lamp may have been around for half a century but certain things just never get old or go out of style.
The dim but groovy lights hit shelves Sept. 3, 1963. Millions of variations of the pieces have been a hit worldwide.
Edward Craven-Walker, a British inventor, designed the piece after he was inspired by a strange looking egg and water timer he saw at a pub in Britain.
The 60s accessory is based on two liquids which will not mix because of the slightly different density.
Even these days with technology surrounding us, the lava lamp still provides some simplistic entertainment.
