what is a lava lamp?
The lava lamp isn’t a recent invention as such, but they still sell sa favourable amount. The lamp contains wax, which when heated by the bulb, turns the lax almost liuidy and in effect, the wax ‘dances’ around inside the lamp. A bulb at the bottom of the lava lamp allows light and the heat to help ‘melt’ the wax. The lava itself comes in many different colours, as well as the liquid inside the lamp.
The shape can come in many different styles (including circular and oval), though the most common shape the lamp comes in is a rocket like shape.
