Purex bottle napalm for little green army men? I can still hear the bewww...bewww...bewww sound it made dripping off the end of the burning bleach jug. Oh and hairspray flame throwers!!! We also made little rockets fueled with phosphorus carefully scraped from matches.
I was in college before making spray-deodorant flamethrowers. Paper matches (wrapped with aluminum foil) make fine little premade rockets, shot from a bent-paperclip launch rail. In my younger years, wooden match sticks could be used as ammo in a "gun" made from a modified wooden spring clothespin (the spring became the trigger, propellant, and igniter). Matchheads were reserved for "bolt bombs", where you walk along rail tracks until you find 1 big nut and 2 bolts that thread into it, fallen off a train... half thread one, load the charge, and loosely thread the other from the opposite side, then throw against some hard surface.
