Are you a fucking moron?
NO flash powder, especially in something for AIRSOFT.
And if you don't even know the power of it, why the HELL are you playing with it?

Ive been working on a few things occasionally.
I have an unfinished wimshurst generator sitting on my porch.
I've gathered most of the parts necessary to make a co2 laser. If anyone has a zinc selenide HR or a 95% reflective OC lens for sale pm me.
I'm making a hand-forged sword currently. I have the blade mostly done, it still needs tempered and ground down a bit. I'm going to try to cast an aluminum hilt for it also.

Perhaps you would be better of keeping your assumptions to yourself. Anyone that does adequate research before making flash powder will be fully prepared for it's power.

Mentioning you don't play airsoft is even more concerning, since it morphs this from 'terrible game play idea' to 'IED experimentation' as far as I can tell.

The first time I ignited a sample of flash powder (a composition of ~2.2km/s) in any quantity above .50g, I was actually surprised by the lack of power compared to what I was expecting.

Discussion of IED's is not permitted on this board, regardless of you intents.

I guess all we can do is thank God that you aren't playing with any of the big boys.

BC, my mom's cousin is a pyrotechnition, and he made a sample of FP using magnalium and perchlorate in a 50:50 ratio. He only made about an ounce, but when e set the stuff off, unconfined, it sounded like a well confined 10g aluminum/perchlorate salute. There's a video on youtube of a guy setting off a 25mg sample, and it sounded like a firecracker!

You assume mine 'sucked'? It was in the 2.2km/s vicinity, which I can assure you is higher than your KNO3/Mg mixture.
I don't know how ou can make an assumption like this, perhaps I am just not as giddy over explosives as you are? I don't get very excited over relatively small bangs. (Yes, sorry to break your heart, flash powder is a small bang)

Any explosive device you are making with FP, by the government's definition, not my own, will land you in serious shit for being an IDE.

The mere thought of you using peroxides, especially ones so prone to form fairly dangerous monomers, is disturbing. MEKP is a much safer alternative, and people on the strictly chemical side of things seem to prefer even nitroglycerin for stability and safety.

Da Pneu Kid, not sure what you are getting at, but an oz is more than twice the size of a 10g salute, and both mixes you mention are more powerful than what spudblaster here is talking about. I'm not sure of your point...


I'm not saying Flash Powder is weak, I am just calling SpudBlaster a dumbass. Let's all keep things clear.

Srry, I meant to say gram. The mix he made was ridiculously more powerful than regular Al/KClO4 powder. I meant that unconfined, a sample of MgAl/KClO4 is as loud as a 10g AL/KClO4 salute. Srry about the mistake.
And I also meant that the weak FP he was using was nothing compared to this.

And you measured the deflagration velocity how?

2.2km/s is far from deflagration. This is the accepted value for the composition I used.

I do enjoy watching relatively small explosions.

I guess I assumed you were beyond this point. My mistake.

Flash powder usually produces a small explosion, until you start to increase the quantities to the point of several hundred grams. Even then, it does not compare to several kilograms of APAN boosted ANFO detonated by an HMTD cap.

For once we agree.

Maybe where you live. Laws and regulations are different in Canada.

Walk in and slap one of your little toys on the desk of the nearest LEO. See what happens

Why would it be disturbing?

Anytime I cannot verify, and have reason to suspect someone isn't trained in a field such as this, I get a disturbing feeling. Can't be helped.

I can assure you that I know at least as much as you do about the chemical properties and safe handling of organic peroxides.

To criticize me for assuming the level of your knowledge, and then making assumptions about mine is very hypocritical of you. Tsk Tsk.

Monomeric AP, and even dimeric AP does not form in significant quantities when the synthesis is done properly.

Even then, it is a stupid risk to take when there are much safer alternatives out there.

I don't make MEKP because I do not have a good source of pure MEK, and I find it cumbersome to transport and use, being a liquid and all. I generally use HMTD, as it is marginally more stable than the trimeric form of AP.

HMTD's relatively short shelf life is another big advantage, as no one wants HE's laying around.

Don't be so presumptuous.

I maintain the right to presume whatever I please, at my own risk.

made a wrist rocket, a hovercraft, and im working on a pedaling soap box. my parents say im only allowed on the comp for 1 hour during the weekend and then never agin till the end of school. which is only another week.

I've made many things
I'm still working on my hovercraft, I like balistic stuff I've made many crossbow things for pencils, I used to do incredible powerpoints that astonished classmates and teachers, not just flipbook stuff, but even games, scence selection. I once ran a buissnes in summer camp making stoneage weapons, it was sucsessful the first time around then customers lost intrest. I once got a little into ruberband guns I made my own invention for a fully-automatic-moterless-crankless-rubberband-gun mechanizm I wanted to get a patent but those are dificult and expensive to get. I studied small arms a lot and designed some as well knowing I'll probably never make them, then I retuned to spudguns where I can build my ideas.

ive been working on a rc hovercraft and still working on m normal sized hovercraft. i also build tons of balloon guns and balloon gun rifles. and i like to work on dirtbikes.
