Another great thing to do with flares is to hold them like a gun and shoot them at people you don't like. You get the pain, the death, the bang!, but also a pleasing light effect. There's one firework you can get in the black market of Naples which is called the Maradona. It's huge, it sets off a light blue flame, and is responsible for a dozen or so deaths. It's actually been reclassified officially as a WMD.
