Lava Lamp

Beginner 🎓 Education / Academia

Definition

A decorative lighting fixture consisting of a glass container with a heat source at the base, containing two immiscible liquids (typically wax and colored dyed water) that form slowly moving blobs when heated. The mesmerizing effect made lava lamps iconic symbols of 1960s counterculture and remain popular retro décor.

Example Usage

His dorm room was decorated with a purple lava lamp that glowed softly through the night.

Origin

Invented in 1963 by British accountant Craven Walker, who originally called it the 'Astro Lamp'; it became known as the 'Lava Lamp' in the U.S.

Fun Fact

NASA has studied the motion of lava lamps to understand fluid dynamics in zero gravity, and lava lamps have actually been taken to space as part of educational experiments.
