I keep most of my PSK on a keychain and in my wallet. I liked the way the coated cotton works , but i hate the mess of trying to get them out of a kit. So I hit on a discovery, chapstick burns like crazy!!! I keep a chapstick on my keychain and the other day i was practicing my fire making skills and had a hard time catching the plain cotton ball with a spark, little windy. long story short... i grabbed the chapstick smeared a cottonball with it and tried to spark it. WOW!!! it caught right away!! and burned hot and for atleast 2 minutes.
Just thought i'd pass it along
