Lets talk about those long burn torches. These usually take less work and resources to make while giving you a longer span of light. One method is using a cattail. If you have any kind of oil on you, simply dip the cattail in the oil and light it like a candle. I have had these burn for nearly an hour. Animal fat can give you oil to perform just as well as say olive oil. Maybe that’s not a resource available to you.
