When you're surviving in the wild there's no running to 7-11 to grab some snacks. It's all up to you. This excellent instructional video teaches you how to build and set an Asian trail spring trap. Primarily, this trap would be used for medium sides animals as they make their way along a forest trail. The trap requires a heavy object near the trail (ideally a rock, or fallen log), a length of fine, strong cordage, a 4ft piece of sapling and several small branches for this device's triggering mechanism. It's a snap! Literally.
