The lava lamp invented in the 1950’s by Edward Craven Walker. He made the well-known design and made it work while trying to build an egg timer. His invention became the most common thing you see in a modern teenager’s room. Although it invented in the 50’s, the concept took off in the 1960’s. Remember those times when you were free to do whatever you wanted, those magical times full of rock’n’roll? The spirit still goes on with the help of the lava lamp.
History is…history. Let’s focus our attention on the way that lava lamps work. They also called “liquid motion lamps,” but we will go with the famous name. In the light, there are two liquids which are unresolved in one different and have close densities. I’m not going to go detailed on the fluids. At the bottom of the device there is a heating zone, often it’s a bright light bulb. The liquid that is heavier absorbs the heat also starts to heat up, therefore expanding. As it does this, it enhances less dense. Because the two fluids have similar densities the balance suddenly shifts and the liquid rises.
All in all, if you are a teenager and you like unusual things, a lava lamp is the thing for you.
