Groovy 80s Hippy Style Blue Lava Lamp Party Light

Lava lamps consists of an illuminating bulb, a glass bottle containing water and a translucent mix of wax and carbon tetrachloride, and a metallic wire coil. The metallic wire coil is hidden in the base of the lamp on which the glass bottle is sitting. The wax is slightly more dense than the water at room temperature, and slightly less dense than the water under marginally warmer conditions because the wax expands more than the water when both are heated causing it to rise in non-uniform blobs.
