Completely off-the-wall in an entirely non-cooking fashion...

For some reason my thoughts went to using it to heat up massage stones. That way you don't need to use actual cookware (for anything other than heating the water initially), and you have a simple way of putting together a hot wrap if your muscles are sad.


That said, I have no knowledge of these things and am not sure it would a) be a good idea, and b) not set things on fire.
