Lava lamps were all the rage in the 1960s — the perfect time to debut something that created such a surreal-looking landscape.

In fact, the liquid motion lamp’s inventor, Edward Craven Walker, reportedly once said, “If you buy my lamp, you won’t need to buy drugs.”
“Light of a million moving shapes…”

The concept behind the lava lamp is fairly simple: Take two materials that don’t mix, and put them together. In this case, it’s basically wax and water.

When the wax reaches the top of the lamp (the point furthest from the heat source), it cools — and so becomes heavier again and sinks.

The whole heating and cooling then repeats over and over, in all its ’60-style glory.

What makes lava lamps flow?

As we mentioned, there are two components in the lava lamp: a wax compound and a liquid compound.

The wax — the “lava” — is said to be a blend of paraffin and perchloroethylene (PERC, aka dry cleaning fluid or brake part cleaner).

The liquid part is a mixture of distilled water, pure salt, antifreeze (ethylene glycol) and a coloring agent.

The two different blends are then are sealed inside a heat-resistant glass container, which is then placed upon the heat/light source (usually a 40-watt light bulb).

The exact ratios of all the components in both the water and wax elements need to be carefully calibrated to align their specific gravities to make the lava lamp work as expected (and to not have the wax break up into little blobs or just hang in place).

Although the specifics are considered a trade secret, the guys at OozingGoo.com have done a pretty good job of figuring it out. In fact, if you have the patience, the materials and the equipment, they will even tell you exactly how you can create your own lava lamp.

The lava lamp backstory

The lava lamp — under the name Lava Lite — was introduced to the US in 1965. While the initial marketing didn’t play up the groovy angle, it wasn’t long before the light with the colorful, undulating glow caught on with the younger generation.

By 1967, the Lava Lite was being promoted with hyperbolic copy that included lines like “like wild – way out!” and “Eerie, ghostly color plus scintillating, sinuous motion… ever-changing – ever-different – never predictable.”

Lava lamp notes

As you can probably tell from the ingredients, the components of a lava lamp — whether self-made or bought — are quite toxic. So we’ll come right out and say it: Do not drink the contents of your lava lamp.

If you want to try making a non-toxic variant of a lava lamp using materials you probably have at home, get an easy homemade lava lamp how-to here. And if you’re looking to go the really simple route, you can just download the any one of several lava lamp apps for your smartphone.

    it seems like my old school lava lamp has a curcular coil inside with the wax and liquid…do you know why? extra heating help??

      The spring-like coil is to break the surface tension of the falling blobs of wax so that they mix with the pool of wax at the bottom
