Has anyone else here ever thought of using these things for survival? A typical cold pack contains the ionic compound ammonium nitrate sale which reacts with water. If you are stranded in a hot & dry place (like last nights Surviorman), an instant cold pack can come in handy. It can cool you off, and in a pinch you can drink the water inside the pouch(before crushing the dry stuff into it). Any thoughts on these things?
