How does this work

Does anyone have any ideas how that works, exactly, if it can store heat until needed yet it doesnt take batteries but does have a switch, and solidifies when its hot (rather than when its cold).

Got something similar.
It's a gel in a plastic pack. You boil the pack for 5 mins. It cools and solidifies and then you "activate" it by pressing a metal disc, this reacts with the gel and it heats up. Lasts about 1-2 hours and then you need to re-boil and cool.
Make your own

the switch is actually a peice of metal and when you deform it the energy released heats up the surrounding material as it has a very low boiling point.
Kin hell Nerv, sensible science stuff. You OK?

you rock stars, is there anything you don't have?
VD?
no, you've definitely got that. the good news is you cant get it twice, no matter how hard you try. which means you're indestructible. probably.
