I'm writing a comprehensive essay on explosive theory and mechanics for the EmE at the moment. Either way, I think it would be a good idea.

Nope...

Pyrodex is a blackpowder substitute with similar characteristics as blackpowder but enhanced safety. The smokeless powder in other ammo is nitrocellulose...

Yeah SP is much difernt, if it was is=n an estes rocket it would shoot out a brith yellow/orange flame. Also SP comes in small circels not a powder. I nearly burn myself the first time i light some SP i thought it would just puff like bp but it shoot up a 4 foot flame from about 1/4 teaspoon of powder.

1/4 teaspoon is very little for 4 feet high.

Sp burns a lot slower than bp. I always confused pyrodex and smokeless most all the time.

I've said it once and I'll say it again just to make sure you all have heard it: All Estes/Quest rocket engines contain BP. No rocket motors that I know of contain Pyrodex. As 6C said, black powder is gun powder, and neither are the same as Pyrodex or smokeless powder. As it relates to the topic of this post, any of the above substances will work in a combustion-based pressure explosion (like the "Soca bottle bombs" described by zero.)

A little proofreading never hurt anyone.

Which explains why you misspelled "soda".

Regardless, your information is correct. Black powder and pyrodex perform very similarly, while smokeless powder is generally unsuitable for salutes.

Smokeless powder, however, can be detonated as a high explosive with a blasting cap. It is, in fact, the most powerful and most readily available commercial high explosive to the civilian market. It requires no permit and in many places not even so much as an ID check to buy.

You do not have to crush up the powder, but it works a lot better. Also, only use the white tipped ones. If in a good case, it will make a good firecracker.

You got 5 dollars? You can get about 50 grams of black powder for 5 dollars, they are in the model rocket engines, if you are desperate. You can get a weak black powder from bottle rockets, and a weak flash powder from the sparklers, but it must be in a very fine powder.
You can use a empty rocket engine case for a tube, or roll your own thick tube out of kraft paper. You can make really good plugs from dowels or epoxy. Everything is at walmart except for fuse. You can order fuse from cannonfuse.com, but it will not get to you until next week. I would just use the sparklers as a fuse.
