How do you make the coolgardie safe?

To make a Coolgardie safe, you'll need a wooden frame to hold a water-soaked cloth or burlap, which acts as a heat-absorbing surface. Place a container of water at the top to keep the cloth damp, and ensure there is good airflow around the safe. The evaporation of water cools the air inside, helping to preserve food. For optimal results, position the safe in a shaded, breezy area.
