Step 7How this works
This is called a solar still.
What happens is, the sun's heat evaporates only the pure water from the moist soil. The water vapor rises to the poncho where it condenses into water drops. After a while of this, the water drops build up and roll down the the middle of the poncho where they then fall into the container.
This gives you pure water from your urine.
