How does the Instant Hot Pack work?
Similar to the Instant Ice Pack, there are 2 layers to the pack; inner and the outer. With the Instant Hot Pack, there are no granules, instead the inner pack contains a non toxic liquidchemical. Upon breaking this inner pack, the liquid contained by the outer layer, will slowly react into a soft solid, which produceds the heat. Up to 55 degrees celsius can be reached by the Instant Hot Pack. Over time, all the liquid will turn to solid (the opposite of the Instant Ice Pack).
