| How it works The galvanised iron tray was filled with water. The hessian bag was hung over the side with one of the ends in the tray to soak up the water. Gradually the hession bag would get wet. When a breeze came it would go through the wet bag and evaporate the water. This would cool the air and in turn cool the food stored in the safe. |
| The Coolgardie Safe was named after a little mining town in Western Australia. It was invented in the late 1890's because the weather was so hot. It was usually placed on a veranda and where there was a breeze. The Coolgardie Safe was made of wire mesh, hessian, a wooden frame and it had a galvanised iron tray on top. |
