Pyrotechnic question: educated responses only please!
    #2893889 - 07/15/04 06:00 PM (12 years, 11 months ago)

Alright....my friends and I are currently working on a series of sketch comidies, one of these is going to involve an explosion. Now, we have cloudy dirt explosions down to a T (a modified spud gun) however we need a fireball type explosion for this one. I know how to create this effect (diagram below) however I need some help in choosing the right powder, see I need "lift powder" that is going to burn at just the right speed to push the gas up into the air correctly. I don't have the funds or equipment to make quality lift powder so I am going to resort to commercial black powder, and I have read this is ok to use. My question is, what speed/burn rate of powder do I want, FFFF, FFG, etc? Anyone know their shit about this type of stuff? And by the way the detonation of this device will be in a safe area with a wireless detonator, so its all good! :thumbup:

You should try white gas or gasoline if you want a good fiery explosion.

The anarchist cookbook is bullshit.


It all depends on the diamiter of your canon and how far you want the projectile to fly.

What are your specs?

Don't worry to much about lift and stuff. Purchase or make 2FA or 4FA (blasting grade) powder if you can, or get Cannon Grade or 1FG powders as substitutes from your local gun shop. (they have about the same grain size).

Pros use 2FA or 4FA for maximum lift and burst.

If you are cheap you can mix potassium pergamanate with aluminium bronze for some pretty kickass powder.
