Hi,

would a mix of f.i. 82% Ammonium Nitrate, 8% (applicable) Fuel and
10% Acetone Peroxide be cap sensitive ? Or even more than cap sensitive ?

I remember most commercial used explosives are mixes of lots of AN with
little amounts of Glycerine Tri- or Glycol Dinitrate and some other
ingredients, and they are well cap sensitive.
(They are wide spread in germany and named Donarit or similiar).

Furthermore, may 250g of this compound be able to prime greater ANFO
loads or are they not powerful enough ?

Please excuse my ignorance, but I had understood hexamethyltetramine to be
the substance I buy for my dry-fuel campstove, or "Esbit Cooker".  I haven't
bought any for years, but it is small (about two cubic inches or less) cakes
of crumbly resin-like stuff, usually white with a bit of yellow color if
it's pretty old.  It lights easily with a match and burns quite slowly
and fairly cleanly if the ventilation is good.  I believe this was standard
issue to soldiers of some WW2 armies.  A piece about 3" x 2" x 0.3" 
(as I recall) burns for nearly half an hour (slightly quicker if broken)
and is about enough to boil a quart of cold water.

More recently, I've acquired a few tiny cakes as fuel for a Stirling engine
kit from Edmund Scientific.

This stuff isn't very "pyrotechnic" by most people's standards.  If it's
not hexamethyltetramine, does any one know what it *is*?

I haven't been a regular reader of this group, but I'll watch for a while 
to see if anyone's familiar with this stuff.  If it *is* a form of the
chemical described above, would it be a useful 'raw' material?

Last summer I filled a 2 liter plastic soda botlle partially full of
warm tap water, about 3-4" worth. I then dumped in a few chunks of
dry ice. We then screwed on the top of the bottle TIGHT and ran like 
crazy.

After 2-3 minutes of strange noises (plastic under stress) the container
exploded with a huge mist of water (probably ice crystals due to the huge
drop in pressure). The noise was deafening to say the least and I was worried
it would shatter nearby windows.

My 10year old son LOVED it.

The largest piece we found was a piece 1" long by 1/2" long - who
knows where the rest of it went?

If you do it yourself, a few cautions are in order:
1-Only do this in plastic bottles. Glass or metal containers could easily kill
  you or anyone in the area. 
2-The time delay is unpredictable and very variable. There is simply no way to
  predict when it will detonate so RUN away and STAY away until it detonates.
3-Dry ice is dangerous to touch or hold. Use gloves or spoons. If it touches
  your skin, it will damage it due to the extreme cold (-112F).
4-Its LOUD!


Be careful out there...

I see your poing about the gunpowder goig out when submersed, but that is only
assuming that the "flame" gets "wet", and since it's does not disolve in water,
and the reaction ("burning") is independant of a oxigen source and thus probably
wont go out when under water.  But too be sure I'll try it.

I'm not sure that you will ever be dealing with preasures great enough to cause
detonation, unlesss you confine it in a metal container or thick glass.

What i like most about gunpowder disolved in acetone is that it's very sticky,
and sounds like a very effective substitute for napolm.

Yes, what you have described is infact hexamethylenetetramine, a molecule
with a tetrahedral structure formed from mixing a formaldehyde solution with an
ammonia solution. At the corner of the tetrahedral structure lurks a nitrogen
atom which is joined to a CH2 group along the sides. It is otherwise known as
Hexamine and Urotropine and is commonly used in organic chemistry and as 
heat tablets. It is available at both chemists and camping stores and
is used in the manufacture of the explosives; RDX, HMX, HMTD and various
other derivatives. All of these explosives are very powerful, some are
very unstable and others are terribly carcinogenic.

I don't know about RDX being the choice anarchists explosive. It is easy to
synthesise if you know what you're doing, but getting access to enough
nitric acid (sg 1.5-1.52) can be a bit troublesome. It would take a
very dedicated anarchist who can synthesise such an explosive in bulk.
Anyway, where you see anarchist, read terrorist and their mainstay explosive
would seem to be AN based such as ANFO. You can't beat ANFO in performance/
cost ratio and it can be used in very large quantities (hundreds of kg) with
relative safety.

Often said by morons.  Anarchism is a movement for social change, and as
the title of one anarchist pamphlet puts it, "you can't blow up a social
relationship".  (The subtitle is "The anarchist case against terrorism":
it was produced by a group in Queensland.  Since it was never widely
circulated, I'll send a copy to anyone with an OCR who is prepared to
scan it in and make it available over the net).

The point of anarchism is doing away with power relationships like those
between bosses and workers, priests and worshippers, governments and
subjects, husbands and wives, adults and children.  Ultimately the way
for a worker to get rid of a boss is just to stop him *being* a boss:
that cannot generally involve stopping him existing by blowing him to
dogfood, though *some* (a very small minority) of anarchists have thought
that setting an example along those lines might be a useful tactical step:
"propaganda by the deed", it was called, and even the people who believed
in it never assumed it would have any other function than to act as an
inspiration to workers in a wider struggle.  The final step is just to stop
obeying bosses.

An interesting book on the political realities of propagandizing with high
explosive is Louis Adamic's "Dynamite" (Rebel Press), a history of sabotage
in the USA.  Turns out that, over the last 100 years, the organization most
given to nitro-group politics (the state apart, of course) was of all people
the AFL between WW1 and WW2.  Read the book to find out why.

Followups redirected to a more sensible place.  Rec.pyrotechnics is going
through a bad patch with this sort of mad-bomber stuff right now (as if
napalm had anything to do with pyrotechnics!): please don't cross-post there.

 You did this? Did you inhale the gas? When N2O decomposes with heat,
several other nitrogen oxides are produced along with N2O. Some of them
are very poisonous, such as NO and NO2.
 A question for the chemists out there: What is the structure of N2O? Is
it a resonance stabilized hybrid of several structures, inculding one
where the two N's and the O are a three membered ring?

Beside the soap solution for creating napolm, there is also another solution
that i recently came upon, gunpowder.  It will disolve in acentone to produce 
a thick and very sticky mixture, not only that, but once inginted it is almost
imposible to put out, since the gunpowder will burn by itself, and acetone will also.  The thing is that it will continue to burn even under water.

I haven't actually tried it, but it certanly sounds like it sould work.  
Anyone have any other ideas about it (whether or not it would work?)

If you want to build one that has no risk of bursting in your hands,
use propane cylinders.  The ID of a common propane torch cylinder is 
just the right diameter for a friction fit.  Cut the ends from
several with a pipe cutter, weld them together and you're ready 
to fire.  If you weld this "barrel" to one of the short, fat propane
torch cylinders whose top has been cut out with a hole saw and use
the short fat cylinder as a cobustion chamber, you'll achieve
phenomenal range.

	I have never tried the soap and gas stuff, but I have a 
simple receipe for napalm. Get white styrofoam, the brittle crackly
stuff works the best. (you know the stuff when you break it little
beads fly everywhere.) Get a glass jar. Oh, you will need lots of
styrofoam :). Break or cut the styrofoam up and put it in the glass
jar. Now get some paint thinner (the cheaper the better). Pour enough
paint thinner to fill about an inch or so in the bottom of the jar.
Let it dissolve the styrofoam (note you may need to add more paint
thinner). Take out the white slime that is left over and light it.
It will stick to anything and is the consistancy of thick jelly
and will burn quite hot for a while. (Burned a hole through a 
metal sliding board once, real thin metal. Yes, it did stick to
the slidigng board.)

	You can use gas too, but I always liked the results from
paint thinner better. also gas gives it a yellowish/orange flame the 
thinner is more of a blue.

Good luck and Be safe,

I tried the acetone-gunpowder misture, and it apears that the resulta are 
much less than satisvactory.  Too bad, I was kinda hoping to find another use
for it.  

One thing that i did try, is putting the acetone-GP mixture on a nicrome wire
and since it's very sticky it works really well.  From there after it dries,
all you need is a nice batery (i used a 6V sealed lead-acid).  Now you don't 
have to spend a fortune for those rocket igniters.

 It has been said that RDX is the explosive of choice for anarchists and
terrorists alike. Probably because of its high explosive nature, alongside
its ease in preparation. I might add that hexamethyltetramine is easilly
prepared by allowing a mixture of ammonia and formaldehyde solutions to
evaporate. Stoichiometry isn't critical as both reactants are gasses, but
I would try for a 3:2 formaldehyde/ammonia ratio.
