How to Use a trash bag to supplement water in the desert

This video is about how to supplement water in the desert using a trash bag. You find a tree that is edible and not poisonous and you open the trash bag and place it over a few of the branches with leaves and seal the opening off. Then you take a little cord and tie off the corner of the bag and find something heavy to weigh the branch down. You want to make sure the corner of the bag is down so that all of the water will run down to that corner. When you feel some water in the bag you can cut a hole where the knot is and let the water run out into your cup or what you are drinking out of.
