 My name is Specialist Fletcher Grant, I'm in the United States Army and we are currently in South Africa and some of the South Africans taught us how to produce water using nature and I'm going to show you how to do so in some simple steps. You need a non-poisonous, very green tree, a plastic bag, sunlight and time and you can make your own water. So first step, you have to make sure the tree is actually green, looks generally healthy. Make sure the leaves look healthy and you have to make sure that the tree is not poisonous. So a good way to do that, that we learned, is to break up a branch and look for a white milky substance in the branch. If there is no white milky substance, also to tell a way if it's poisonous, you take it and you can actually stick it in your armpit under your clothes and you leave it there and you get a generally itchy sensation, the tree is obviously poisonous. But in this case the tree is not poisonous so I'm going to take this out. All you need is this one plastic bag in order to help produce water and so what you do is you take generally like leafier branch and you take the plastic bag and you put the branch inside of the plastic bag and you get as much green as you can inside of there because the more green you have the more evaporation you have and the more water you can contain inside the bag. Once you get it tied and not wrapped around the branch and you get it nice and secured you can tell that there is little to no space for any evaporated water to leave. You leave it in the sun for a few hours and you can come back to some water. For example, what's going to happen after you get done with that process, if you look up here this one was tied around 9am this morning and it is 3pm our time and you have a pretty good amount of water and also you still have time for more water to come because the sun hasn't set yet but by sunset we should have a good amount of water and that's how you produce water using a generally green tree.
