I'm not sure why, but for some reason I want a Lava Lamp

@djsumdog I used to have one but the lightbulb wasn't strong enough to melt the wax and I don't think it was replaceable.

@xianc78 @djsumdog I wonder if there's a more efficient way to do this without needing as much energy.

You would need a liquid that would be able to do the same thing, but at the temperature of a high powered LED .... and not be toxic to clean up if it breaks.
