As far as motion lamp recipes go, a study of the aforementioned emergency room patient provides more detailed information than do patents and corporations.Gas chromatography-mass spectrometry analysis of the patient's blood and the remaining lamp liquid revealed components mostly consistent with Walker's patent.But here's food for thought for those with an insatiable thirst for liquid motion lamps: The study concluded that PEG was probably to blame for the kidney toxicity.

The journal didn't name the manufacturer of that particular lamp. The story goes that Edward Craven Walker, leader of a World War II Royal Air Force squadron and a nudist filmmaker, drew inspiration for the groovy lamp from a pub's egg timer.

But most people would call it a Lava lamp, the trademark name for one company's product that's widely used to describe liquid motion lamps and their characteristic undulating flow. The patent literature suggests that there is some truth to that tale.

Walker was certainly the first to commercialize the lamps, which went on to embody the "Age of Aquarius." Those early patents aren't easy-to-follow recipes, but they do discuss how the kitschy lamps work.

The random motion captivates people's interest, and is something that other collectibles very rarely recreate, notes Anthony Vassallo, a liquid motion lamp collector who helps maintain the tribute websites Additional agents, he explains, help the wax gently plume upward instead of breaking apart into bubbles as it is heated and keep wax from sticking to the sides of the container. Spain tells C&EN that only five or six staff chemists know the formula and are in charge of occasional reformulations.

"You never know how the lava is going to flow." Water and wax, which the original patents name as main ingredients, remain components of the commercial recipe, says Tom Spain, vice president of sales, marketing, and product development for Haggerty Enterprises, the official U. Densities must be recorded for each batch of wax that Haggerty makes, which is mixed in 5-foot-tall vats in factories in China.

Last but not least, the water layer is added to the cooled wax very slowly so as to avoid creating emulsions, which are cloudy-looking oil-water mixtures.

In fact, the recipe for the water layer is carefully adjusted to perfectly complement the density of each unique batch of wax.

The shapely vessel houses two main ingredients that are mutually insoluble.

The key to the lamp's ever-changing serpentine flow is to closely match the density of the two layers.

A heat source tweaks the density of one component so that when warm, it is less dense than the other component and so floats to the top.

Upon cooling, it is denser than the other component and sinks to the bottom. patent mentions additives such as dye, mineral oil, carbon tetrachloride, and polyethylene glycol (PEG), but the exact formula of commercial lamps is a trade secret.
