Want a fool proof firestarter? Doesnt break...no moving parts...works when hot/cold/wet/windy/at any altitude? First get a misch metal rod--the kind you scrape with a blade to give off wicked hot sparks. Then get some 100% cotton balls (not the synthetic stuff), and a a jar of vaseline. Now get a cotton ball and a gob of vaseline and work it into the cotton ball. Really saturate the cotton with vaseline and work it into the cotton. Now when you need a fire, get one of those cotton balls and fluff it up--tease the fibers apart and try to really fluff it up. Now strike the rod and aim the sparks onto the cotton. You can easily make it burn for 7 minutes!! If you want to extend the burn time, place it on a bottle cap from a beer/soda bottle so the melting vaseline can be trapped on the bottle cap--essentially making it like a candle. These things will burn when wet, windy, at any altitude, etc. Best of all, for $5 and a trip to the dollar store, you can have a life time supply of fire starters.
