The Lava Lamp was created in the early 60s by a British engineer by the name of Craven Walker in an experiment gone awry. Nobody can remember what Walker was trying to create, only that he started a craze like no other.
It was, and still is – the popularity of the lamp has endured, a long cylinder inside which a wax like substance is heated.
This heating causes the substance to slowly bubble, float and move about the glass cylinder.
Illuminated by a soft light within, the “lava” continues to move endlessly.
