The Astro lamp, or lava lamp, was invented around 1963 by Edward Craven Walker.It was adapted from a design for an egg timer spotted in a pub in Dorset, England. Edward and Christine Craven-Walker licensed the product to a number of overseas markets whilst continuing to manufacture for the European market themselves under the original name of the company, Crestworth.

Lavarand, also known as the Wall of Entropy, is a hardware random number generator designed by Silicon Graphics that worked by taking pictures of the patterns made by the floating material in lava lamps, extracting random data from the pictures, and using the result to seed a pseudorandom number generator.

Common screw-in bubble light. A bubble light is a decorative device consisting of a liquid-filled vial that is heated and illuminated by an incandescent light bulb.Because of the liquid's low boiling point, 39.6°C (103.3°F), the modest heat generated by the lamp causes the liquid to boil and bubble up from the vial's base thus creating a decorative effect.
A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
All lava lamp tests produced violent reactions, with the reactions differing depending on the lamp's design: When lava lamps with safety caps exploded, they vented their contents out through the tops of the lamps because of the safety caps popping off (as designed). The Build Team then tested a bottle-capped lava lamp, which leaked due to a ...
