Battery to ignite a flame
by Johnny
(Canada)
You take 2 "D" batteries and open (they can be dead or still good) then take out the carbon rods be carful not to break them! Take a "9 volt" and take each of the carbon rods and put one rod in the + and one in the - then touch both the rods together. It creates an arch.
Have dry tinder and touch the "arch" and blow gently this will ignite a flame! Trust me on this, it does work!
Make sure you have the basic wilderness skills to safely enjoy your trip.
