A friend of mine of a few years ago used to work in the oil biz. He used to
pump LN2 down *DEEP* holes to get more oil out... One of the jobs was being
done in the middle of the Araibian Sea off a 10000 ton freighter with the
LN tanks and pumps on the fordeck. The injection pressures run up to
10K atm by the way. 
One day a hose failed. All and sundary dived for cover as the pumps unloaded
5000 gal of LN2 real fast... all over the foredeck. There was a LONG loud
grown and a huge bang.
The result was an 18' gap all the way to the bilge! The ship was carefully
returned to port, and when a ranting manager demanded to know what they 
thought they were doing was told " It's broken "
this same group of fun guys did even better latter on in the same general
area.

I'm reposting this article from it's previous title because of the numerous
homosexual advances I have gotten from a ucsb address.
I'm looking for a homemade substance that will explode with the noise of
an M80 firecracker.
I don't want it cased in metal or anything as I don't like shrapnel and don't
want to hurt anybody or anything.
I just want a simple boom to liven up the neighborhood.

you meant FLAME, of course.

Two other ways to mitigate flame:

	- make sure the temperature of the exhaust gases is below their
	  ignition point. (difficult to engineer, as the reaction is
	  likely to extinguish if too much of the produced heat is
	  carried away)

	- chemically inhibit open flame.  The simplest way to do this
	  is to add CCl4 (carbon tertrachloride, available at some
	  hardware stores as a cleaning agent) to the smoke compound.
	  The CCl4 fumes will snuff the open flame. They will snuff you
	  too, if the room ventillation is inadequate.

Historical note: CCl4 was once used for the purpose of extinguishing
fires.  You can still see some automatic CCl4 sytems on old boats.
The CCl4 is contained in a glass ampuole which is suspended about 1 meter
above the floor.  It is held up by a temperature sensitive doodad
which drops it if there's a fire.  The CCl4 spills all over, and the
fumes smother the flames.  Too bad it kills people.

Unfortunately, it probably contains phosphorous, which is a trick to
obtain...  however, it is pretty easy to make igniters out of paper
matches.

For larger engines, use whole matches, for smaller engines, cut the
matches in half lengthwise.  Use a new razor blade, and you should
have no problem cutting them w/o the head crumbling.  Once you have
the appropriate width match, cut a slit in the top of the head and
center a piece of nichrome wire about 2" long or in the slit.  Then,
run one half of the nichrome wire down one side of the match and
the other half down the other side, bend out pigtails (like estes
igniters) and secure with masking tape.  Voila.  It takes about 10
seconds when you get good at it, and each igniter probably costs
no more than 5 cents.  Just be sure to cut the slit perpendicular
to the flat side of the match, otherwise the head will probably
fall apart.

Good luck!

Dissolve up as much of the chloratre mixture as you can in HOT water. Allow 
the water to cool slowly, and crystals of the chlorate will form, decant off
the excess water and filter off the crystals.  Put the crystals out in the 
sun to dry (or in a warm place).  Repeat the process with your crystals if 
you want to further purify them, but one recrystallisation should be enough.
Be aware that you won't get anywhere near all the ClO3 out.

By the way, if you're using chlorate in a fertiliser, I'd give up gardening
now, if I were you, while you've still got some plants..... :-)

Well, the finished product is quite a change from the earlier files, with
a LOT more useful information, and a few deletions.

THE good news: 102 pages, with:

A full index, cross-references, several appendices, and a complete table
of contents. Photos of many neccessary lab setups are included, as well
as numerous diagrams.

The bad news: to make room for the pictures and diagrams, the section on
locks was removed, as well as the stuff on boobytraps and other borderline
subjects.

The first NINETY (90) orders will received signed and numbered copies, with
the other 10 (numbers 1-10) will go to a few major contributor's, with

Good advice. However, it is interesting that the commercially produced flash
powders I have purchased came in plastic containers. They said to do the
mixing in those containers. The flash comp is not the best around, it is
rather slow - the aluminum is fairly course. Maybe they feel that this was
sufficient to eliminate any static danger.

I did not do so. I used a wooden cup and rolled the mixture together in the

I haven't been following this discussion, but I just thought I would
throw in a caveat that KMnO4 is supposedly not all that safe to work
with in pyro comps.  Perhaps someone could post some info on KMnO4?  I
just know that it is quite reactive.  A strong soln of potassium
permanganate will oxidize paper or metal with little to no provocation
(unlike, say, KClO4).  So I would be a bit leery of using it in pyro
compositions.  I have made flash powder from it, which was nifty,
although I have forgotten why.  Maybe the color of the flash?

  Oh I like to read R.Pt, and I Like to do HMTD and TNT and RDX, But I
never ever blow up cans, because it can throw a metal stripe towards
me.  Thanks for warning, Jeremy, You propably saved my life !!

  Anyway one visually most beautiful pyrotechnical device ( after 30
kilogram red-coloured smokebomb in shopping mall ... :-) ) is a small
piece of TNT attached into a 200 gram butane Camping-stove cartridge.
I can warmly recommend it. It's really a wonderful blast, when
suddendly, after a small bang a 30 feet bright flame ignites the
night. I have never tried this with  flours or carbondust, but when
you compare Butan, fine wheat flours and carbon dust into a small
200 gram TNT explosion, I can only imagine the flash ... ( small
stripes of aluminium plates might also be worth trying.. )
  BTW terrorists use next recipe to create a temporay hell into the

How thick was the plastic?  Plastic is much like a capacitor.  The more mass it
has the more energy it can store.  That is why plastic baggies are not much of
a worry.

Many companies do not want to create the hotest flash, because that costs more. 
They want the CHEAPEST flash possible.  You can tell that someone is being
cheap when a salute can comes down with an end blown out!

You would 'die' if you saw how commerical companies make it.  25lbs at a time
(well the law now says 10lbs). SIFTED 3 times is very common.  The sifting
really does make a difference in how hot the flash will be.

Well, if you've only got a couple people doing the pulling, you only need it to
work once and they're busted.  All you need to do is make it *clear* that all
future offenses will be prossicuted, and FOLLOW THROUGH on the next offense. 
That'll put any other offenders at bay.  Another alternative is a camera of
some sort at each alarm.  When an alarm is pulled, +click+ and smile, you're on
candid camera.  If the camera is hid well enough, no one except those who
install/service/develop the film will know how the pullers are getting
identified.  Taht solution is somewhat expensive, though, but you could go out
and get those cheapo little "disposable" cameras and use them...
