Lava lamps: 50 years old and still groovy
LONDON (AP) - Call them '60s relics or hippy home accessories, lava lamps have been casting their dim but groovy light on interiors for half a century, having hit British shelves 50 years ago on Tuesday.
A British company began marketing their original creation as an "exotic conversation piece" in 1963. Since then, millions of models of the much-copied invention have been sold worldwide.
The design was created by British inventor Edward Craven-Walker, who was inspired by an odd-looking liquid-filled egg timer he saw in a pub in south-west Britain.
The former World War II pilot then spent years transforming the concept into a home lighting accessory, having recognised the potential for such an invention during anything-goes '60s Britain.
