Get bacon and cook the fat off of it. Then take aluminu foil or some other mold and put the brease and fat into it. Leave in f***** to harden and insert wick while hardening.
Salt Peter and sugar. That's pretty damn easy if you ask me. Put it in a skillet or frying pan and heat it on medium to high. Then mix the two together in the pan and put into a mold that won't burn through. Place a slow burning wick into it and let it harden. Light it and throw it at someone.
