The Perfect Edge

Senior Airman Joseph Collett, a survival, evasion, resistance and escape instructor, teaches the "bird's nest" technique of building a fire by igniting a small piece of flammable material with flint rocks and placing it inside a "nest" of weeds while blowing air into the nest to help the flame grow.
