A water trick my Native American grandmother taught me

You will need a large clear plastic bag for this and it does not give you tons of water but it will give you enough water to survive in a pinch. Here's what you do; look for the oldest non-poisonous tree that you can find. Take the leaves off the tree and put them in the clear plastic bag and lay it in the sun. The water from the leaves will condensate into the bag and give you water. The older the tree, the deeper the roots, the cleaner the water. You can do this on a cloudy day as well but it will take longer for the condensation to take place.
