If you use the large straws from Mcdonalds uses for their milkshakes you can cut them in half and make two firestraws with several vaseline covered cotton balls. You melt wax into the open ends to seal them from water. When you need them, you just cut them in half and light with a spark maker. I usually put one straw and a sparker in the ammo holder on the buttstock of my gun. That way, I've always got one if I grab my gun and go. I've also used the vaseline from one when I had really chapped lips while on a hunt.
