The heavier liquid absorbs the heat, and as it heats up, it expands. As it expands it becomes less dense. Because the liquids have very similar densities, the formerly heavier liquid is suddenly lighter than the other liquid, so it rises. As it rises, it cools, making it denser and therefore heavier, so it sinks.
How does a normal lava lamp work?
Well, lava lamps are designed so that the temperature at the top is a bit cooler than at the bottom. … So when a glob reaches the top of the lava lamp, it contracts. It becomes denser than the surrounding liquid and begins to sink. When it reaches the bottom, the whole cycle repeats!

The aqueous phase may be water mixed with alcohol or other water-soluble solvents.
What is the science behind a lava lamp?
When enough bubbles pop, the water-and-remaining gas becomes more dense than the oil. So the ball of water sinks down through the oil and joins the rest of the water. Changes in density as gas is added to or taken away from water cause it to float up and sink down through the oil. Thus the lava lamp is created!
Can a lava lamp be left on all night?
While it may be tempting to operate your lava lamp all hours of the day and night, this can cause it to overheat, which may make the colored blobs stop moving in an amoeba-like fashion. … A lava lamp may overheat in eight to 10 hours, depending upon the bulb and brand of lamp.

Are lava lamps toxic?
Laboratory tests are done on leftover parts from AW’s lava lamp. Wax, kerosene, and polyethylene glycol are found, all dissolved in water. Wax is, in general, non-toxic in humans. Kerosene, at least in the amount that could be found in a lava lamp, is not poisonous, but the polyethylene glycol, could be a problem.
Do lava lamps use a lot of electricity?
Lava lamps use the heat from an incandescent light bulb to heat the wax. The larger the surface area of the bottle the more power they need. If we size a bottle by the liquid depth (bottom of bottle to liquid surface) : Small lava lamps : ~5″ (liquid height) use 15W bulbs, ~6″ use 25W bulbs.
Do lava lamps cause cancer?
Lava lamps do not directly cause cancer. However there are ingredients in a lava lamp that has known potential causes of death, such as kerosene, if consumed. But it is not known to cause cancer. Basically, do not drink the contents of a lava lamp.
