Lava lamps are one of the most mesmerizing objects ever.
The lava-like liquid slowly flowing through colored wax is fascinating to watch, and also very relaxing. Some people even find it hypnotic.
But what’s the science behind it?
The lamp works because of density: liquids with high and low densities (like water and oil) can’t mix no matter how hard you try. When you turn the lava lamp on, heat from the lightbulb warms up the wax until it becomes less dense than room-temperature air, so the wax starts to rise. As it gets further away from the bulb and cools down again, it becomes more dense than air and sinks back down. This continues on for hours, although, you should never leave it on for more than 10 hours or it could overheat.
The lamp’s container is made from a heat-resistant material so it doesn’t melt under the lamp’s heat. That’s good because they can get pretty hot, so be careful not to touch while it’s running or it could burn you.
