The space between them should be filled with wet sand and the top should be covered with wet material. When the water evaporates, it pulls the heat out with it, making the inside cold.

It is considered the most natural, the cheapest and the easiest-to-do fridge. Thus, the foods keep fresh for much longer period of time. Isn't it a nice alternative idea to packs of ice while camping?
