The lava lamp was invented by Edward Craven-Walker of the United Kingdom in 1963. The slowly rising and falling blobs fascinated people in the 1960’s and still do today. Making various simplified versions of the lava lamp is a popular science project. This is the place to find answers about the history and the mysterious workings of the lava lamp.
lava lamps by Yvonne Bernal The unique lamps were created by a British inventor and former World War II pilot, Edward Craven-Walker, who reportedly thought up the idea after seeing a homemade, liquid-filled egg timer at a pub. In September of 1963, Craven-Walker started a company to research and…

The lava lamp uses a process called convection. As the wax heats up, it expands, creating a greater volume so its density decreases. This makes it less dense than the surrounding liquid, causing it to rise. When the wax reaches the top of the lamp, away from the heat source, it begins to cool down. …

But certain types of fluids are always used -- one is generally water-based, and the other is generally oil-based. The water-based fluid might simply be water mixed wi…

The "lava" is a mixture of carbon tetrachloride, mineral oil and paraffin wax. The liquid it floats in is water. The light source is a 40-watt light bulb. When the bulb melts the wax, it will do the lava thing on its own.

The 'lava' in a Lava Lamp is actually a chemically treated wax. The clear (sometimes colored) liquid is water.

The heat source at the bottom of the lamp (usually light bulb) heats up to a very high temperature. With wax lava lamps the solid wax needs to melt first. Once the wax is liquid, it will start to absorb heat from the light bulb. Once it has collected enough heat, a blob will float to the top to cool…

A lava lamp is a pretty interesting thing, when it is cool, it looks like it's made of candle wax, because it is. Wax is strange, because when it is hot, it rises, but when it is cool, it sinks, so the bulb at the bottom heats the wax, and it floats to the top, but at the top, when it starts to cool…

Warm water and dish detergent does the trick. In our case, the gooey insides were bright red and landed on splotches on a light green carpet. It took a bit of scrubbing, but we got it all out of the carpet. The smell is a different story, and the unlovely scent of kerosene or antifreeze lingers.

It all depends on how long your lamp has been turned on. As it heats up, the wax flows in more of a long stream and then as it rises and falls, it breaks up into smaller balls.
