Knowing how to find water in the wild is an important thing to know if you find yourself stranded in the wild. After all, you can survive for weeks without food, but only a day or two without water.
If you want to make water out of nothing, you don’t use heating elements, you use condensation. One pretty basic way you can collect water is to make a belowground still. To do this, you’ll need some square piece of plastic sheeting, a digging tool, a container, a drinking tube and a rock. You can see how it works on a picture below.
This works, even though it works very slow. You will need quite a few for a single person’s needed ration. You’ll be digging a lot of holes if you are taking care of even a small group. You will get maybe a glass of water in one day (just enough to keep you from dying quickly).
You can also force moisture through plant respiration. It’s called transpiration technique.
Tie the bag around the leafy green tree branch. Condensation rises and the plastic must be over the plant material or the condensation will escape. Weight the inside with a rock. After a while, poke a hole to drink the water or pour it into a container for later. It is very important to use non-poisonous vegetation.
Heat would make the moisture in the plants evaporate faster. Then it could circulate to the plastic and condensate. But, that way you will need to be gathering live plants and making new pits daily. A living plant will keep drawing and respiring moisture.
Getting lost or stranded in the wild is something that could happen to just about anyone. Staying hydrated is essential while camping, hiking or just spending time outside. Hope this will help if you ever need to find water in the wild.
