Soil moisture pit

1. Dig a hole 2m x 2m x 1m.
2. Take an empty water bottle and cut the top off.
3. Make a small hole in the center for the bottle.
4. Cover the large hole with a sheet of plastic wrap.
5. Place a small rock on the plastic wrap over the water bottle.
6. Let the sun do its job.
The water bottle should fill at least once a day, which is enough to keep you alive. Probably won't work in cold weather.
