Dissolve 1/4 tsp potassium nitrate in 1 tablespoon of water.
Moisten one two-ply paper towel with this solution, squeeze and refold repeatedly to make sure solution is evenly distributed
Allow it to dry. Or force it to dry with moderate heat.
Once dry, this paper will burn much like a fuse, with little or no flame.
Unfortunately, it will not burn through small openings, so its uses are limited to open-air burning.
