full text A build-it-yourself solar still is one of the
best ways to obtain drinking water in areas where the
liquid is not readily available Developed by two doctors
in the US Department of Agriculture it’s an excellent
water collector Unfortunately you must carry the
necessary equipment with you since it’s all but
impossible to find natural substitutes

The only components required though are a 5＇ 5＇ sheet
of clear or slightly milky plastic six feet of plastic
tube and a container — perhaps just a drinking cup —
to catch the water These pieces can be folded into a neat
little pack and fastened on your belt To construct a
working still use a sharp stick or rock to dig a hole
four feet across and three feet deep Try to make the hole
in a damp area to increase the water catcher’s
productivity Place your cup in the deepest part of the
hole Then lay the tube in place so that one end rests all
the way in the cup and the rest of the line runs up —
and out — the side

Next cover the hole with the plastic sheet securing the
edges of the plastic with dirt and weighting the sheet’s
center down with a rock The plastic should now form a
cone with 45-degree-angled sides The low point of the
sheet must be centered directly over and no more than
three inches above the cup The solar still works by
creating a greenhouse under the plastic Ground water
evaporates (evaporation) and collects on the sheet until
small drops of water form run down the material and fall
off into the cup When the container is full you can suck
the refreshment out through the tube and won’t have to
break down the still every time you need a drink
