Hot air can be cooled by the evaporation of moisture. This principle is used by the desert pack rat to air condition its underground nest. Any source of water can be used, even water contained in freshly cut grass. The pack rat gathers and stores vegetation within the compartments of its nest. Tunnels connect these compartments to the rest of the nest and allow the moist air to circulate and cool the entire nest.
The pack rat's own body waste is even used as a source of moisture for cooling. The tunnel first passes through the pack rat's bathroom, and the body waste is not removed from the nest until all of the water has evaporated. During long hot spells, the pack rat even brings droppings of larger animals into its nest to provide additional water for its air conditioning system. One can't help but wonder how the little guy figured all this out. Maybe he had some help from his Creator!
