Lava lamps are very nice things to have. I love to sit and watch lava lamps.

One thing that could make them even better is to impregnate the wax with a thermochromatic dye that changes colors at the same temperature that the wax changes bouyancy from float to sink (and vice versa). And maybe the liquid inside. Then we'd have a multi colored shifting lava lamp.

You could watch the thermal currents, not just the wax.

Now that's an idea!

Very excellent.

hmmm not quite thermoelectric but not a bad idea...

Cool - now get back to coding!

Essentially the same as a previous idea on Halfbakery. (see link). Redundant...?
