According to the figure, the first step of obtaining water outdoors is to find a hole with green plants on its bottom. Next, remove the green plants in the middle and put a container there. Then, cover the hole with a plastic sheet and place two stones on both ends of it to secure its position. A third stone is laid on the middle of the plastic sheet so that the middle part is also the lowest part.

When the sun shines on the green plants in the hole, water evaporates from these plants. The vapor rises up and then cools down to form water drops on the plastic sheet.
