Let the Sun Shine
Place your Solar Still on a flat surface in the sun, and leave it alone for a few hours.
Clean water will begin to separate from the dirty by evaporating up with the sun.
Our plastic wrap will then catch the clean water at the top and create condensation.
That condensation will then trickle down to the center due to the weight of our rocks until it eventually falls in our clean jar.
After a few hours, you'll have a nice glass of clean water.
