Claim 0:
1. A cooling apparatus, comprising:
a container having a container wall and being surrounded by atmospheric pressure;
a 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. for a humidification liquid at said A DRY GAS pressure greater than atmospheric pressure; and
a second chamber within said container and being filled with said humidification liquid that is removed from said dry gas at said dew point temperature range; separated from said first chamber by a barrier material insoluble in said humidification liquid,
an interconnection structure interconnecting said first chamber and said second chamber, said interconnection structure containing barrier material insoluble in said humidification liquid and internally abutting and initially sealing said interconnection structure;
such that when said container is opened and said container interior is exposed to atmospheric pressure, said dry gas pressure expands said interconnection structure collapsible wall 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 within said second chamber; and said vacuum collapses said collapsible wall 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.
