[QOUTEWouldn't you want the BP to be as fine as possible? I'm just thinking after getting it wet, and clumping it up, even when run through a very small sieve (mesh strainer kind, right?) it wouldn't be as fine as it would be simply dry mixed... Or would having it in larger "clumps" (though they would be very small granules as you put it) increase the surface area making it more explosive, where as if it was very fine, it would burn more as fuel, like a model rocket?[QUOTE]

Your right there, grains a few millimeters in size is used as 'lift' while rammed/pressed into 1 large grain of fuel in a tube would be slower burning i.e. rockets and fountains.

there is a whole topic on making charcoal give it a read before you try making some.

Just a pointer, don't take anything on totse.com seriously, a lot of that is seriously dangerous, not far from techniques in texts like "the anarchists cookbook".

I would have to agree, makes me think of the JRC, very irresponsable and likely to cause serious injury or death if some of those are copied.
