Watching a lava lamp in action can be pretty mesmerizing, with its large bubbles swirling around and morphing. However, if you’ve ever wondered about the physics behind how a lava lamp works, you’ve come to the right place. In this post, you’ll learn everything you need to know about the mechanics of lava lamps. <\/p>\n\n\n

What Is Lava Lamp?<\/h2>\n\n\n

Lava lamps<\/a> are decorative tube-shaped light fixtures containing colored oily fluids that flow up and down the lamp in a way that evokes the flow of molten lava. As the liquid inside the lamp rises and flows, it splits into different-sized globules that twirl around to create a psychedelic effect. <\/p>\n\n\n\n

We owe the invention of the lava lamp to an English engineer, Edward Craven Walker<\/a>. He first got the idea of the lava lamp from a prototype he saw in a pub in the late 1940S. However, it wasn’t until 1963 that the lava lamp as we know it today came into existence. <\/p>\n\n\n\n

How Does a Lava Lamp Work?<\/h2>\n\n\n

Contrary to the name suggests, lava lamps don’t use volcanic lava whatsoever. The name lava lamp typically comes from the rising and falling action of the lamp’s globules. This lava effect results from the interaction between the different fluids used inside the lamp. <\/p>\n\n\n\n

Conventional lava lamps usually use two different fluids selected based on their densities such that one floats within the other. It would help if you also considered the coefficient of expansion of the fluids. This allows one to rise or sink faster than the other when you subject them to heating. The most common fluids used in commercial lava lamps are water and wax.<\/p>\n\n\n\n

When the bulb at the base of the lava lamp heats the heavier fluid (wax) at the bottom of the lamp, its temperature increases, causing it to become less dense and rise to the top. As it approaches the top of the compartment, it starts to cool and become more viscous, thus sinking back to the bottom. You can repeat this process several times until it creates the mesmerizing effect for which these lamps are known. <\/p>\n\n\n\n
