BP Explosives Well, BP'rs, we have been challenged if the old codgers have any bang left. With permission of the esteemed author I forward the following. All scientific results are expected to be posted on BP. I have read your guys' email about m-80's and such... all quite wonderful, but apparently your recipes have gotten a little dusty... Oliver's purple flame "smoke bomb" add two parts sugar to one part potassium nitrate in an old soup can. place several model rocket igniters in the mixture and ignite. It will shoot out a large purple flame and an extremely thick smoke; enough to cover a city block. by the way... It will melt the can. Now for the potassium pemaganate. (that stuff also cures trench foot.) Oliver's contact explosive get a small glass jar. put a little bit of gasoline inside and shake it, to effectively cover the walls of the jar. Let the gasoline evaporate inside the jar by setting it in the sun for a while. open the jar just enough to put your drop of potassium permaganate in (from an eye dropper) and then quickly close it. If you chance to throw this jar against a wall hard enough to break the jar, a fireball proportionate to the size of the jar will seemingly magically appear. Have fun and don't lose any fingers! DISCLAIMER: nobody else is responsible for your actions.
