I don't think that is all there is to it. The page says they are filled with "Phase Change Material" (which I would guess is some sort of wax) that melts at !40F. I don't know why that would be better or worse than a lump of metal though.

Apologies for going meta, but it's refreshing to see that I'm not the only one who uses capital 1's from time to time.

It's much more likely to be a fusible alloy such as Wood's metal or Field's metal. My guess is that it's closer to Field's metal, since it is non-toxic and has a melting point very close to their advertised ideal.

Good guess about the wax.
