lava lamps

Lava lamps are decorative lighting fixtures that create dynamic visual effects through the movement of colored wax inside a liquid. When heated by a light bulb at the base, the wax becomes less dense and rises through the surrounding liquid. As it cools near the top, it becomes denser and sinks again, forming continuous, graceful blobs. This cycle produces captivating, ever-changing shapes and motion, highlighting principles of fluid dynamics and density. Lava lamps are both aesthetically appealing and an example of how heat can influence the behavior of different materials in a confined environment.
