The groovy lamp is filled with a liquid combination of oil and water with wax accents to achieve a relaxing look. This item needs electricity to work. It comes with a standard UL plug in. Just simply plug into your standard plug. Wait for 4-5 hours for the wax to melt and start seeing the action. It is used weight and density between the wax and liquid. When it melts, wax becomes lighter than liquid hence it flows up. When the wax reaches the top, it cools down. It becomes heavier than the liquid so it goes down again.
