Claim 10:
11. A cooling apparatus with a collapsible walls subjected to a pressure greater than atmospheric pressure and forming a first chamber and a second chamber within said apparatus; said first chamber containing granulated endothermic chemicals with interstitial spaces filled with a dry gas having a dew point temperature range 10° F. to −150° F. fora humidification liquid at said pressure greater than atmospheric pressure; said second chamber separated from said first chamber by a barrier material insoluble in said humidification liquid; said second chamber filled with said humidification liquid that is removed from said dry gas at said dew point temperature range; such that when the apparatus is exposed to atmospheric pressure, said dry gas expands away from said barrier material and exposes said humidification liquid vapor to said dry gas and said dry gas absorbs said humidification liquid vapor forming a vacuum with said apparatus; and said vacuum collapses said collapsible walls into a minimal volume by absorption of said humidification liquid in to said interstitial spaces causing a first cooling of said apparatus collapsible walls; and said endothermic compounds react with said humidification liquid to cause a second endothermic cooling of said apparatus collapsible walls and said first and second cooling cools any medium surrounding said collapsible walls.
