How Do Motion Lamps Work

In a liquid motion lamp, the heat usually comes from a light bulb. 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.

How long does it take a motion lamp to work?

Lava lamps should start working within an hour to an hour and a half of turning them on. First they will form stalagmite shapes, then they will start to form lava lamp shapes. Please note, new bottles will take longer to heat up (up to three hours), but the heating time will decrease after several uses.

How do liquid motion timers work?

Liquid motion timers entertain with tiny colored “bubbles” that slide from one level to another on plastic shelves suspended in liquid. Timers like these often grace desks in office cubicles, home offices and college dorm rooms.
