lava lamps contain blobs of coloured wax inside a glass vessel
Caption
lava lamps (or Astro lamps are a decorative novelty item, invented by British accountant Edward Craven Walker, the founder of Mathmos, in 1963. The lamp contains blobs of coloured wax inside a glass vessel filled with clear or translucent liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel.
