Place a small rock in the bag to weigh it down.
If you have a piece of tubing, a small straw, or a hollow reed, insert one end into
the mouth of the bag before closing (remember to tie off or plug the tubing
so that air will not escape). This will allow you to drink the condensed water
without untying the bag. Then tie the bag securely shut as close to the end as
possible; it’s important to maximize the amount of air space in the bag.
Place the bag on a slope in full sunlight. The mouth of the bag should be
positioned higher than the base of the bag (which contains the rock), to keep
the bag from slipping or blowing away and to keep the water dripping to the
lowest point.
To drink: If you don’t have a tube to draw the condensed water from the still,
loosen the tie around the bag’s mouth and drain. Retie the mouth securely
and reposition the still to allow further condensation.
Change the vegetation in the bag after extracting most of the water from it, to
ensure a regular supply of water.If you can’t fill a bag with vegetation, tying it to the end of a branch with lots of leaves
will do the trick. Just make sure it’s in a sunny spot. If this tree had been poisonous, the
water it produced could also have been poisonous. Don’t take chances unless you’re sure
of the source tree or bush.
