H2O2

flash powder is only used because of its bright light, there are way more energetic materials.

The general consensus is DONT DO IT!

Arguing wont change the facts of life and how substances behave.

Of course there are more powerful things than flash powder. Just thinking thats the most powerful energetic substance most people will come into contact with, and bearing in mind 50mg of flash is the maximum allowed in the US.
I also do a bit of pyrotechnic work and flash isn't just used for it's bright flash. There are many forms, but most commonly it is used for the loud report and brissance, which is used to break shells (http://www.pyroguide.com/index.php?title=Aerial_Shell).

[rp181]

its 5g, not 50mg.

As much as I like energetics and solid propellants, this isn't the place to discuss them.

Unless someone is still talking about using highly concentrated H2O2 in a spudgun, this thread has kind of outlived its usefulness (if there ever was any ).

"Firecrackers can contain no more than 50 milligrams of flash powder per cracker."

Brissance to describe a 1.3 material?? That's a new one on me.

And I would argue that nitro-cellulose is the most powerful energetic that the public comes in regular contact with.

'Fraid I don't do pyrotechnics, but I am in regular contact with materials such as CL-20, HMX, RDX, NG, etc.

I told you the truth when i said i wanted to use the stuff in a spudgun. As a general rule i dont lie about the ways I use explosives on the internet. I am aware acetone peroxide and H2O2 are, and have been, used in terrorist weaponry. I do realize the stuff is unsafe and unstable. But the 35% stuff is more safe, of course, than the 60% I though i could use earlier. Perhaps we should focus less on the peroxide, and more on the gun. Couldn't a steel chamber hold the pressures exerted by the gas (of cousre used in low quantity)?I mean, it is beyond my ability to build a steel gun, but couldn't a safe peroxide gun made of steel work safely?

You could just thread a bunch of galvanized pipes together to make a steel gun, ya'know. I hope a monkey wrench ain't beyond your capability.

[magnum9987]

Its not. But my house doesnt have many pipes lying around. the cheap bastards who built my house took all surplus.

Sure. But I guarentee it can't be done by *YOU*.

1) You need a very good understanding of what consitutes safe (which you obviously don't).

2) You need the finances to be able to build a clean fueling system and such (read: it'll take more than just plumbing fittings).

I find it HIGHLY unusual that you would contemplate such a fuel for your FIRST spudgun.

And this statement you made;

" As a general rule i dont lie about the ways I use explosives on the internet."

Raises concerns as well. Is this one of those "times"?

Why would you decide that you need a fuel with more"umph" than the commonly accepted, safer, and easier to obtain fuels such as hair spray, propane, butane, mapp gas etc. ?

Further, why do you come to this conclusion without having built anything before?

I have to wonder, just what the hell ARE you up to.

Uhh dimwit, they took the surplus because it's their pipe.. That stuff costs contractors real money...it's not up to them to supply your spudgun hobby, what little there is of it at this point....

[TurboSuper]

Mmm...what I find funny is that a 6' gun is considered "small". Are you the jolly green giant?

[brogdenlaxmiddie]

I still stand by my previous posts. Your an idiot for thinking that we'd go along with this idea. Don't try it. I believe that Mr. Crowley once said "You should put some unregged Co2 in a plastic bottle. You'd be surprised of the performance." (or something of those lines ) I think that would be safer for you in comparison of using H202 in high concentration. especially since your showing little to no REAL knowledge in regards to the chemical reaction of the substances. But seriously Mag, I think your smarter than this.... (or at least I hope)

[rp181]

If you were really intenet on building an oxidizer cannon then 2 things:
You would know there are better and safer things to use as an oxidizer.

2: Wouldn't steel chmabers be unsafe due to high concentrations of liquid oxidiser on it?
