Lava lamps were invented by Edward Craven Walker in
Britain and first marketed in 1963. He was inspired by an
egg timer he saw in a pub. It had been created by a Mr.
Dunnett who was by then dead. Craven Walker spent the
next 15 years making a better lamp.
His psychedelic invention fitted perfectly with the ‘swinging
60s’ and sales took off around the world. The invention
is patented and the recipe for the contents are supposed
to be a secret.
"If you buy my lamp, you won't need to buy drugs."
"...starts from nothing, grows possibly a little bit
feminine, then a little bit masculine, then breaks up
and has children. It's a sexy thing.“
Edward Craven Walker
