Start a Fire With a Magnifying Glass or Lens

Starting a fire with a magnifying glass or a lens has become one of my favorites.  It’s a very cheap and fast way to start a fire only if the sun is out.  I have used both magnifying glasses found here and lenses shown in the video below which can be found here to start fires in less than 10 seconds.

This video on starting a fire with a lens shows in detail how to also prepare your wood before you attempt to start the fire to ensure it lasts.
