I have been playing with my various spark generating toys and decided that I have been using perfectly dry tinder in an ideal situation. Built confidence and skill but had me worried about that time when I and everything else was wet.
I took a cotton ball and rubbed some vaseline on it. Worked it around a little and then tried to make sure the outside of the ball was well coated. Probably used about 3-4 peas size worth of vaseline total. I dropped it into a cup of water. It floated. I took a piece of fatwood about finger sized and pushed it to the bottom of the water. Left both in the water for several hours.
I came back and fished both out. I squeezed as much water as possible out of the cotton ball. Then I opened it up hoping to find mostly dry cotton on the inside. I made a fuzz stick of the fatwood. Then I partially split the finger sized fatwood fuzz stick into about 6 sections. I only split the fatwood about 1/3 the length. I made a few more fuzz curls on the new splits. I pulled the cotton ball apart some more and pinched it between the 6 finger splits of the fatwood. It began to look like a rake or fork with cotton spacers.
I threw some sparks from either my BSA HotSpark or SparkLite. I had both out and was playing around with both. It only took two or three strikes and the cotton caught. It flamed and caught the fatwood on fire. I had a 2-3 inch flame for several minutes between the vaseline cotton and fatwood. I only allowed it to burn down 1/3 the length of the fatwood. I was able to hold the other end of the fatwood stick with no difficulty. My son mentioned it would make an excellent torch to explore a cave or something.
Anyway I proved to myself that even if I fell overboard, swam to shore during a rainstorm, and everything around me was wet, I could get a fire going with a few simple things to carry. The flame was sufficent it would have easily dried out any small kindling collected and I could have added larger pieces to dry and burn. Alternately I could have only used half the fatwood to hold the cotton ball and the remainder split up as my kindling. A finger sized piece of fatwood would easily burn 10 minutes with a 2-3" flame.
Once you get confident with dry tinder, I recommend you try building fires in less than ideal situations with either wet tinder, gloves, or one-handed. Increase the difficulty continually. Soon, starting a fire with dry tinder will seem painfully easy.
