Creating a solar still

My brother just gave me instructions via Gmail chat on how to create a solar still to make clean water while on water restriction in Nashville.

Jason: if I remember correctly

you dig a hole

cover with plastic

put a vessel (empty) in the middle and put a small rock on top of the plastic and center over the vessel to catch the water that condenses on the plastic film

follow?

I suppose you could put river water in the hole to up the moisture content in the still and thus produce more water

full sun

i think
