Let’s find out how they do their magic.

How do lava lamps work?

Lava lamps work based on the two main ingredients, and that would be wax and a liquid. The interesting thing is that those two compounds do not mix, and that is the main reason why they create such a playful and spectacular. The lightbulb placed at the bottom of the lamp has the role of heating up the wax.

In the initial stage at room temperature, the wax will be denser than the water, but when the heat comes into play, the wax will become less dense and it will begin to float. As it floats up and moves further and further away from the heat source, the wax cools down and becomes more solid. When the wax reaches the top of the lamp and becomes denser than liquid, it will sink again.

The cycle is repeated continuously until you turn the lamp off. It is a very interesting and easy principle to understand if you want to know how do lava lamps work.
