Man, you are thirsty. You vaguely remember something about a solar still. What do you need to make one?
Answer A plastic sheet, a container, a hole, and vegetation or contaminated water to distill into purified water.
There are various methods of making a solar still. The principle is the same. 1. Dig a hole. 2. Enclose vegetation, contaminated water, or even urine (anything that contains moisture) into it, as well as a container to catch the distilled liquid. 3. Enclose the hole with plastic, making sure the lowest point is centered over the container.
