ok newbie. you seem new here so i wont flame you and i will show you the ropes about these specialised forums (not general discussion boards like spurious generalties). hopefully you dont learn the hard way
1) inquiries about explosive mixtures belong in the board "backyard ballistics", and the application of these for (hypothetical

) illegal purposes belongs in "bad ideas". "mad scientists" does talk about chemistry sometimes, but is mainly theoretical in nature. we also talk about physics, maths and the like here
2) in these subforums, you need to elaborate. you also need to sound like you actually know something. if you dont, do some research. I can bet 10$ that if you bring this to backyard ballistics, you
WILL be branded a retard and have your thread locked. explosives are a very serious thing to do, and people who hang out in backyard ballistics are very adept at what they do. which is probably the reason why they are all still alive

.
3) to sound like you at least know something (vital in the board of BB and stuff), you must at least use the word "you" rather than "u". also, give more details. the longer your post is, the more believable it becomes
i really suggest you go there and just read up on the stuff there before posting anything
good luck, and may the force be with you
