Hey does anyone know a substance that can stay cold for an almost infinite   
   amount of time? Cause I would like to know for an example for an invention   
   that got an idea for.   
      
   For example say if you needed your water cold for walking in a desert the   
   coldness of that substance could freeze the air to get fresh water.
