Lava Lamps (1960's) - Mortal Journey
A lava lamp (or Astro lamp as it was originally know), is a decorative light featuring various colored, oozing blobs of wax that rise and fall in a heated and lighted lamp. The lava lamp was invented by Englishman Edward Craven Walker in 1963 and grew in popularity during the 1960's psychedelic craze.
