The Lava Lamp Night Light from ThinkGeek combines the mesmerizing quirkiness of a 60’s lava lamp with the usefulness of a night light to illuminate those dark corners of your room.
The Lava Lamp Night Light looks great plugged into any wall outlet. A flip of the switch and science takes over. The wax is slightly denser than the oil it lives in, at room temperature that is. Once the light is on and the wax starts to heat up, it becomes slightly less dense than the oil and it rises (and then drops as it cools).
