How to Make A Solar Still
If you are ever stranded and caught without a fresh water source, you may need to make a solar still to get rehydrated. Just follow these easy steps.
- Dig a hole and place a cup in the center
- Place brackish water, urine, vegetation and other sources of water in the hole, but not in the cup
- Place a clear plastic sheet over the hole and weight it with a small rock so that the sheet drops into the center of the cup
- As water evaporates from the hole's contents, it condenses on the underside of the plastic sheet and then drips into the cup
- After several hours there may b e some drinkable water in the cup
- Running a straw from the cup to the topsheet allows you to drink water from the cup without tearing down the still
