okay...this should stop all questions like "wah, i don't know where to get black or flash powder,wah." well ladies here is the easiest, cheapest and maybe not the best way to get it.

1. get your homo self to wal-mart
2. go to the toy section
3. look for the "rocket" part of the section
4. buy a pack of model rocket engines-bout $4.95 for a 3-pack of C6-3 engines
5. next, take a rocket engine and lightly cut down the shaft, cut 1 layer only!!!
6. peel away the paper from the engine
7. you will have a black powder stick
8. put the stick in a sandwich bag
9. get a hammer and lighlty smash the stick into powder
10. use wisely (don't be a retard and blow yourself up)

p.s. at the top of the stick there is a small amount of flash powder

G.H.O.S.T. please bear with me here, i love you like my left nut and this will stop the stupid questions...

oh heres one go to the store and buy some pyrodex....durrr

well guess what? wal-mart is across the nation and you will not be questioned, hassled or flagged for this method of getting 100% pure black and flash powder. so...yea

k, what specific model rocket engine are u talkin about? or will any do?

i'm almost 100 percent positive that that isnt black powder. it works, i've used it, but it is not black powder if i am correct.

also a mortar and pestle works a hell of a lot better than a hammer.

its not that hard to make for yourself and teaches the beginners some basics before they make anything particularly dangerous. just use the search function and i'm sure you'll find many tutorials on the subject

why not just make it yourself

You can make your own; by weight the formula is Potassium nitrate: 75%, Charcoal: 15%, and Sulfur: 10%; do not measure by volume only by weight, use a good digital scale to get the best results. You can get all the materials to make if from: Pyro Creations and Skylighter

EDIT: You will also need a ball mill with lead milling medium in order to make the BP.

Bass Pro Shop, national chain. All kinds of gunpowder in the hunting section. Just tell them you reload your shotgun shells if they ask, or take a trusted adult.

thats a good method too and i find that the C6-3 engine works the best- remember this was for the little noobs that are starting out and don't have a $60.00 ball mill or chemicals or even a scale. i just found that this way is faster but as you may know, not the best. and the fact that wal-mart is everywhere makes this just....so...easy
