Explosives
|
|||
|
|
|||
|
Underground cumputer bulletin boards vary in emphasis. I have seen boards
|
|||
|
that were devoted to finding a mate, remenisient of the want ads in certain
|
|||
|
underground newspapers. Some are primarily interested in software piracy.
|
|||
|
Others are strong on hacking computer systems or phone phreaking. In 1984 a new
|
|||
|
interest appeared which was quite startling to your present author -- do it
|
|||
|
yourself explosives. Though seemingly disrelated to telecommunications, it was
|
|||
|
on the phreakhhack boards that this information began appearing.
|
|||
|
The longest and most descriptive article on explosives ever written for a
|
|||
|
computer bulletin board showed up about the middle of the year on Pirate-80 and
|
|||
|
a few other elite underground systems. About the only subjects of consequence
|
|||
|
not covered by the article are thermite and nitroglycerin both of which
|
|||
|
established themselves early as very popular. Because of its comprehensive and
|
|||
|
representative nature I am prsenting it here in its entirety including the
|
|||
|
warning statement which is a part of the original article.

THIS INFORMATION IS PRESENTED FOR ACADEMIC STUDY ONLY. THE ACTUAL CONSTRUCTION
|

|
OF THE DEVICES AND MATERIALS DESCRIBED IN THIS FILE WOULD BE DANGEROUS, EVEN
|

FOR AN EXPERIENCED CHEMIST. ALSO, THE CONSTRUCTION OR POSSESSION OF MANY OF

THESE DEVICES WOULD BE IN VIOLATION OF VARIOUS FEDERAL, STATE, AND LOCAL LAWS.

INTRODUCTION: The trouble with text books on chemistry and explosives is the
|
|||
|
attitude with which they are written. They don't say, "Now I know you would
|
|||
|
like to blow Holy Hell out of something just for the fun of it so here is how
|
|||
|
to whip up something in your kitchen to do it". They tell you how Dupont does
|
|||
|
it or how the ancient Chinese did it but not how you can do it with the
|
|||
|
resources and materials available to you. Even army manuals on field expedient
|
|||
|
explosives are almost useless because they are just outlines written with the
|
|||
|
understanding that an instructor is going to fill in the blanks.
|
|||
|
|
|||
|
It is a fun game to search out the materials that can be put together to make
|
|||
|
something go "boom". You can find what you need in grocery stores, hardware
|
|||
|
stores, and farm supplies. An interesting point to remember is that it is much
|
|||
|
easier to make a big explosion than a small one. It is very difficult for a
|
|||
|
home experimenter to make a fire-cracker, but a bomb capable of blowing the
|
|||
|
walls out of a building is easy. The king of explosives for the
|
|||
|
do-it-yourselfer is black powder. It is easy to make and when properly confined
|
|||
|
is capable of devastating power. For this reason, I will begin by telling you
|
|||
|
how to make black powder, how to make black match fuse, and how to put the two
|
|||
|
together with results that would please even a wild-eyed anarchist. I will end
|
|||
|
this introduction and begin my instructions with this statement: "I know you
|
|||
|
would like to blow Holy Hell out of something just for the fun of it so here is
|
|||
|
how to whip up something in your kitchen to do it".
|
|||
|
|
|||
|
HOW TO MAKE BLACK POWDER: You will need potassium or Sodium Nitrate, Sulfur,
|
|||
|
and hardwood charcoal. The common name for Potassium Nitrate is saltpeter.
|
|||
|
Sodium Nitrate is sold at farm supplies under the name of Nitrate of Soda. It
|
|||
|
is also called Chile Saltpeter. Sodium Nitrate makes a slightly more powerful
|
|||
|
black powder but has the disadvantage of being hygroscopic (obsorbes moisture
|
|||
|
from the air), so if you use it, store it in tightly closed containers. You can
|
|||
|
also get sulfur at farm supplies as a wetable powder used for spraying. It is
|
|||
|
cheap and works well. Some drug stores sell sulfur under the name Flowers of
|
|||
|
Sulfur. If you use Nitrate of Soda, it will be in the form of prills (little
|
|||
|
round beads). Bake it in an oven at 200 degrees for 10-15 minutes to drive out
|
|||
|
the moisture. Then dump a cup or two into a blender and switch it on. It will
|
|||
|
do a beautiful job of reducin it to powder. Buy a bag of charcoal briquettes
|
|||
|
at a grocery store. Put a few briquettes in a rag and pound with a hammer. Dump
|
|||
|
the result into the blender, grind, then strain through a tea strainer. Mix by
|
|||
|
volume: 6 parts potassium or Sodium Nitrate, 2 parts powdered charcoal, 1 part
|
|||
|
sulfur. This mixture will burn if ignited and will explode if ignited while
|
|||
|
tightly confined. It can be greatly improved, however, by processing it as
|
|||
|
follows: Moisten with water unuil it will stick together when pinched between
|
|||
|
thumb and finger. Press it into a disposable aluminum pie pan. Bake in a
|
|||
|
preheated oven at 200 degrees for about 30 minutes. get it totally dry. Grind
|
|||
|
into as fine a powder as possible. A mortar and pestle is best. If you use a
|
|||
|
blender at this point, there is a danger of explosion. It is not very sensitive
|
|||
|
to friction or impact, but is very sensitive to sparks. If you followed these
|
|||
|
directions, you should have a fine slate-grey powder.
|
|||
|
|
|||
|
When baking black powder, remember to preheat the oven. Place your pie pan
|
|||
|
approximately in the center of the oven. Do not set it on the bottom of the
|
|||
|
oven. These warnings are to prevent hot spots that could ignite the powder
|
|||
|
causing a fire or explosion. Something went wrong once when my father-in-law was
|
|||
|
doing this and it blew the door right off the oven. His training in military
|
|||
|
demolitions included field expedient explosives. The point is that things can go
|
|||
|
wrong even when you know what you are doing. Protect yourself at all times. Use
|
|||
|
common sense. Wear safety glasses; don't stand in front of the oven, etc.
|
|||
|
|
|||
|
HOW TO MAKE BLACKMATCH FUSE: Take a flat piece of plastic or metal (brass or
|
|||
|
aluminum are easy to work with and won't rust). Drill a 1116th inch hole through
|
|||
|
it. This is your die for sizing the fuse. You can make fuses as big as you want,
|
|||
|
but this is the right size for the pipe bomb I will be getting to later. To
|
|||
|
about 122 cup of black powder add water to make a thin paste. Add 122 teaspoon
|
|||
|
of corn starch. Cut some one foot lengths of cotton thread. Use cotton, not silk
|
|||
|
or thread made from synthetic fibers. Put these together until you have a
|
|||
|
thickness that fills the hole in the DIE BUT CAN BE DRAWN THROUGH VERY EASILY.
|
|||
|
TIE YOUR BUNDLE OF THREADS TOGETHER AT ONE END. SEPARATE THE THREADS AND HOLD
|
|||
|
THE BUNDLE OVER THE BLACK POWDER MIXTURE. LOWER THE THREADS WITH A CIRCULAR
|
|||
|
MOTION SO THEY START CURLING ONTO THE MIXTURE. PRESS THEM UNDER WITH THE BACK OF
|
|||
|
A TEASPOON AND CONTINUE LOWERING THEM SO THEY COIL INTO THE PASTE. TAKE THE END
|
|||
|
YOU ARE HOLDING AND THREAD IT THROUGH THE DIE. PULL IT THROUGH SMOOTHLY IN ONE
|
|||
|
LONG MOTION. TO DRY YOUR FUSE, LAY IT ON A PIECE OF ALUMINUM FOIL AND BAKE IT IN
|
|||
|
YOUR 200 DEGREE OVEN OR TIE IT TO A GRILL IN THE OVEN AND LET IT HANG DOWN. THE
|
|||
|
FUSE MUST BE BAKED TO MAKE IT STIFF ENOUGH FOR THE USES IT WILL BE PUT TO LATER.
|
|||
|
AIR DRYING WILL NOT DO THE JOB. IF YOU USED SODIUM NITRATE, IT WILL NOT EVEN DRY
|
|||
|
COMPLETELY AT ROOM TEMPERATURE. CUT THE DRY FUSE WITH SISSORS INTO 2 INCH
|
|||
|
LENGTHS AND STORE IN AN AIR TIGHT CONTAINER. HANDLE THIS FUSE CAREFULLY TO AVOID
|
|||
|
BREAKING IT. YOU CAN ALSO USE A FIRECRACKER FUSE IF YOU HAVE ANY AVAILABLE. THE
|
|||
|
FUSES CAN usually be pulled out without breaking. To give yourself some running
|
|||
|
time, you will be extending these fuses (blackmatch or firecracker fuse) with
|
|||
|
sulfured wick.
|
|||
|
|
|||
|
HOW TO MAKE SULFURED WICK: Use heavy cotton string about 188th inch in diameter.
|
|||
|
You can find some at a garden supply for tieing up your tomatoes. Be sure it's
|
|||
|
cotton. You can test it by lighting one end. It should continue to burn after
|
|||
|
the match is removed and when blown out will have a smoldering coal on the end.
|
|||
|
Put some sulfur in a small container like a small pie pan and melt it in the
|
|||
|
oven at 250 degrees. It will melt into a transparent yellow liquid. If it starts
|
|||
|
turning brown, it is too hot. Coil about a one foot length of string into it.
|
|||
|
The melted sulfur will soak in quickly. When the string is saturated, pull it
|
|||
|
out and tie it up to cool and harden. It can be cut to desired lengths with
|
|||
|
sissors. 2 inches is about right. These wicks will burn slowly with a blue flame
|
|||
|
and do not blow out easily in a moderate wind. They will not burn through a hole
|
|||
|
in a metal pipe, but are great for extending your other fuse. They will not
|
|||
|
throw off sparks. Blackmatch generates sparks which can ignite it along its
|
|||
|
length causing unpredictable burning rates. Now you have the basic ingredients
|
|||
|
to shake the earth like thunder. In the next installment or two, I will tell you
|
|||
|
how to put it all together to do just that. You will find that you have baked a
|
|||
|
very deadly pie. I have twice been accused of setting off dynamite in the woods.
|
|||
|
The explosive power of your little grey powder may exceed your expectations, so
|
|||
|
choose your testing ground with care.
|
|||
|
|
|||
|
HOW TO MAKE A PIPE BOMB: Buy a section of metal water pipe 122 by 6 inches long,
|
|||
|
threaded on both ends. Buy two metal caps to fit. These are standard items in
|
|||
|
hardware stores. Drill a 1116th hole in the center of the pipe. This is easy
|
|||
|
with a good drill bit. Screw a metal cap tightly on one end. Fill the pipe to
|
|||
|
within 122 inch of the top with black powder. Do not pack the powder. Don't even
|
|||
|
tap the bottom of the pipe to make it settle. You want the powder loose. For
|
|||
|
maximum explosive effect, you need dry, fine powder sitting loose in a very
|
|||
|
rigid container. Wipe off any powder that has gotten onto the top or threads of
|
|||
|
the pipe. Gently screw on the second cap. Hand tighten only. Place a small piece
|
|||
|
of tape over the hole and go to your test site. Remove the tape and insert a two
|
|||
|
inch piece of black match fuse or a firecracker fuse into the hole. Place the
|
|||
|
bomb behind a large rock or tree. Using thread or string, lightly tie a 2 inch
|
|||
|
piece of sulfured wick to the end of the fuse. Avoid letting the wick touch any
|
|||
|
objects. This might cause it to go out. Light the wick and head for cover in a
|
|||
|
direction that keeps the rock or tree between you and the bomb at all times. Get
|
|||
|
behind cover at least 50 yards away. You may not expect such a large explosion
|
|||
|
from such a small object. Be extra cautious until You have done this a time or
|
|||
|
two and it gets real what you are dealing with. The pipe will be blown to pieces
|
|||
|
which will fly through the air like bullets. An accident could seriously wound
|
|||
|
or kill you. This is not a big firecracker. It is more like a hand grenade. The
|
|||
|
size of the bomb can be increased by using a larger pipe and caps. To make a big
|
|||
|
noise without blowing up your pipe, cap one end only. Drill a 1116 hole at the
|
|||
|
top of the threads at the capped end. Put in about 3 to 4 rounded teaspoonsful
|
|||
|
of powder. Pack about 2 inches of wadding on top of the powder. Toilet paper or
|
|||
|
facial tissue is good for this. Pack it tight. Open up a safety pin and stick it
|
|||
|
into the hole. Work it around to loosen up the powder so a fuse can be inserted.
|
|||
|
When this goes off, the recoil will be tremendous. You will loose your pipe
|
|||
|
unless you brace it securely against something. The pipe can be reloaded and
|
|||
|
used again. A fun trick is to mount the pipe pointing upward. Drop a tin can
|
|||
|
over the open end and light the fuse. The can will be blown high into the air.
|
|||
|
Campbell's soup cans are great for this.
|
|||
|
|
|||
|
HOW TO MAKE ROCKET FUEL: This is easy to make and fun to play with. Mix equal
|
|||
|
parts by volume Potassium or Sodium Nitrate and granulated sugar. Pour a big
|
|||
|
spoonful of this into a pile. Stick a piece of blackmatch fuse into it; light;
|
|||
|
and step back. This is also a very hot incendiary. A little imagination will
|
|||
|
suggest a lot of experiments for this.
|
|||
|
|
|||
|
ANOTHER ROCKET FUEL: Mix equal parts by volume of zinc dust and sulfur. Watch
|
|||
|
out if you experiment with this. It goes off in a sudden flash. It is not a
|
|||
|
powerful explosive, but is violent stuff even when not confined because of its
|
|||
|
fast burning rate.
|
|||
|
|
|||
|
As I continue from this point some of the ingredients are going to be harder to
|
|||
|
get without going through a chemical supply. I try to avoid this. I happen to
|
|||
|
know that B. Prieser Scientific (local to my area) has been instructed by the
|
|||
|
police to send them the names of anyone buying chemicals in certain
|
|||
|
combinations. For example, if a person were to buy Sulfuric acid, Nitric acid
|
|||
|
and Toluene (the makings for TNT) in one order the police would be notified. I
|
|||
|
will do the best I can to tell you how to make the things you need from commonly
|
|||
|
available materials, but I don't want to leave out something really good because
|
|||
|
you might have to scrounge for an ingredient. I am guessing you would prefer it
|
|||
|
that way.
|
|||
|
|
|||
|
HOW TO MAKE AN EXPLOSIVE FROM COMMON MATCHES: The word "safety" in safety
|
|||
|
matches is misleading. The chemical on the heads of safety matches is a powerful
|
|||
|
explosive. It is similar to black powder but has a lower ignition temperature
|
|||
|
(more sensitive to heat) and unlike black powder is easily detonated by impact.
|
|||
|
This feature moves it up into the high explosives class. To test this, lay a
|
|||
|
paper safety match on ~a hard flat surface and hit the head sharply with a
|
|||
|
hammer. What do you know! It goes bang! To collect a quantity of this explosive,
|
|||
|
it is best to use wooden safety matches. Buy several cartons. They're cheap.
|
|||
|
Note that these should be safety matches, not the strike anywhere kind. Pinch
|
|||
|
the head near the bottom with a pair of wire cutters to break it up; then use
|
|||
|
the edges of the cutters to scrape off the loose material. It gets easy with
|
|||
|
practice. You can do this while watching TV and collect enough for a bomb
|
|||
|
without dying of boredom. Once you have a good batch of it, you can load it into
|
|||
|
a pipe instead of black powder. Be careful not to get any in the threads, and
|
|||
|
wipe off any that gets on the end of the pipe. Never try to use this stuff for
|
|||
|
rocket fuel. A science teacher was killed that way. Just for fun while I'm on
|
|||
|
the subject of matches, did you know that you can strike a safety match on a
|
|||
|
window pane? Hold a paper match between your thumb and first finger. With your
|
|||
|
second finger, press the head firmly against a large window. Very quickly, rub
|
|||
|
the match down the pane about 2 feet while maintaining the pressure. The
|
|||
|
friction will generate enough heat to light the match. Another fun trick is the
|
|||
|
match rocket. Tightly wrap the top half of a paper match with foil. Set it in
|
|||
|
the top of a pop bottle at a 45 degree angle. Hold a lighted match under the
|
|||
|
head until it ignites. If you got it right, the match will zip up and hit the
|
|||
|
ceiling. I just remembered the match guns I used to make when I was a kid. These
|
|||
|
are made from a bicycle spoke. At one end of the spoke is a piece that screws
|
|||
|
off. Take it off and screw it on backwards. You now have a piece of stiff wire
|
|||
|
with a small hollow tube on one end. Pack the material from a couple of wooden
|
|||
|
safety matches into the tube. Force the stem of a match into the hole. It should
|
|||
|
fit very tightly. Hold a lighted match under the tube until it gets hot enough
|
|||
|
to ignite the powder. It goes off with a bang. --- For later projects, like a
|
|||
|
chemical time delay fuse, you will need some concentrated sulfuric acid. So, I
|
|||
|
better tell you how to make it.
|
|||
|
|
|||
|
HOW TO MAKE CONCENTRATED SULFURIC ACID FROM BATTERY ACID: Go to an auto supply
|
|||
|
store and ask for "a small battery acid". This should only cost a few dollars
|
|||
|
(about 4 dollars). What you will get is about a gallon of dilute sulfuric acid.
|
|||
|
Put a pint of this into a heat resistant glass container. The glass pitchers
|
|||
|
used for making coffee are perfect. Do not use a metal container. Use an
|
|||
|
extension cord to set up a hotplate out doors. Boil the acid until white fumes
|
|||
|
appear. As soon as you see the white fumes, turn off the hot plate and let the
|
|||
|
acid cool. Pour the now concentrated acid into a glass container. The container
|
|||
|
must have a glass stopper or plastic cap -- no metal. It must be air tight.
|
|||
|
Otherwise, the acid will quickly absorb moisture from the air and become
|
|||
|
diluted. Want to know how to make a time bomb that doesn't tick and has no wires
|
|||
|
or batteries? Hold on to your acid and follow me into the next installment.
|
|||
|
|
|||
|
HOW TO MAKE A CHEMICAL TIME DELAY FUSE: To get an understanding of how this is
|
|||
|
going to work, mix up equal parts by volume Potassium chlorate and granulated
|
|||
|
sugar. Pour a spoonful of the mixture in a small pile and make a depression in
|
|||
|
the top with the end of a spoon. Using a medicine dropper, place one drop of
|
|||
|
concentrated sulfuric acid in the depression and step back. It will snap and
|
|||
|
crackle a few times and then burst into vigorous flames. To make the fuse, cut
|
|||
|
about 2 inches off a plastic drinking straw. Tamp a small piece of cotton in one
|
|||
|
end. On top of this put about an inch of the chloratessugar mixture. Now lightly
|
|||
|
tamp in about a quarter inch of either glass wool or asbestos fibers. Secure
|
|||
|
this with the open end up and drop in 3 or 4 drops of sulfuric acid. After a few
|
|||
|
minutes the acid will soak through the fibers and ignite the mixture. The time
|
|||
|
delay can be controlled by the amount of fiber used and by varying how tightly
|
|||
|
it is packed. Don't use cotton for this. The acid will react with cotton and
|
|||
|
become weakened in the process. By punching a hole in the side of the straw, a
|
|||
|
piece of blackmatch or other fuse can be inserted and used to set off the device
|
|||
|
of your choice. Potassium chlorate was very popular with the radical
|
|||
|
underground. It can be used to make a wide variety of explosives and
|
|||
|
incendiaries, some of them extremely dangerous to handle. The radicals lost
|
|||
|
several people that way. But, don't worry. I am not going to try to protect you
|
|||
|
from yourself. I have decided to tell all. I will have more to say about
|
|||
|
Potassium chlorate, but for now, let's look at a couple of interesting electric
|
|||
|
fuses.
|
|||
|
|
|||
|
HOW TO MAKE AN ELECTRIC FUSE: Take a flashlight bulb and place it glass tip down
|
|||
|
on a file. Grind it down on the file until there is a hole in the end. Solder
|
|||
|
one wire to the case of the bulb and another to the center conductor at the end.
|
|||
|
Fill the bulb with black powder or powdered match head. One or two flashlight
|
|||
|
batteries will heat the filament in the bulb causing the powder to ignite.
|
|||
|
|
|||
|
ANOTHER ELECTRIC FUSE: Take a medium grade of steel wool and pull a strand out
|
|||
|
of it. Attach it to the ends of two pieces of copper wire by wrapping it around
|
|||
|
a few turns and then pinch on a small piece of solder to bind the strand to the
|
|||
|
wire. You want about 122 inch of steel strand between the wires. Number 18 or 20
|
|||
|
is a good size wire to use. Cut a 122 by 1 inch piece of cardboard of the type
|
|||
|
used in match covers. Place a small pile of powdered match head in the center
|
|||
|
and press it flat. place the wires so the steel strand is on top of and in
|
|||
|
contact with the powder. Sprinkle on more powder to cover the strand. The strand
|
|||
|
should be surrounded with powder and not touching anything else except the wires
|
|||
|
at its ends. Place a piece of blackmatch in contact with the powder. Now put a
|
|||
|
piece of masking tape on top of the lot, and fold it under on the two ends.
|
|||
|
Press it down so it sticks all around the powder. The wires are sticking out on
|
|||
|
one side and the blackmatch on the other. A single flashlight battery will set
|
|||
|
this off.
|
|||
|
|
|||
|
ELECTRIC FUSE # 3: An excellent electric fuse can be bought ready made at hobby
|
|||
|
and toy stores. They are sold for setting off model rockets.
|
|||
|
|
|||
|
MORE SPONTANEOUS COMBUSTION: Some of the ingredients for these can only be had
|
|||
|
from a chemical supply so they are not my favorites. Look for powdered aluminum
|
|||
|
at a good painting supply.
|
|||
|
|
|||
|
METHOD # 1: Scatter out a few crystals of chromic anhydride. Drop on a little
|
|||
|
ethyl alcohol. It will burst into flame immediately.
|
|||
|
|
|||
|
METHOD # 2: Mix by weight, four parts ammonium chloride, one part ammonium
|
|||
|
nitrate, four0parts powered zinc. Pour out a small pile of this and make a
|
|||
|
depression on top. Put one or two drops of water in the depression. Stay well
|
|||
|
back from this.
|
|||
|
|
|||
|
METHOD # 3: Put one gram of powdered potassium permanganate into a paper cup.
|
|||
|
Drop two drops of glycerin onto it. After a few seconds it will burst into
|
|||
|
flames.
|
|||
|
|
|||
|
METHOD # 4: Spoon out a small pile of powdered aluminum. Place a small amount of
|
|||
|
sodium peroxide on top of this. A volume the size of a small pea is about right.
|
|||
|
One drop of water will cause this to ignite in a blinding flare.
|
|||
|
|
|||
|
METHOD # 5: Mix by volume 3 parts concentrated sulfuric acid with 2 parts
|
|||
|
concentrated nitric acid. Hold a dropper of turpentine about 2 feet above the
|
|||
|
mixture. When drops strike the acid they will burst into flame.
|
|||

HOW TO MAKE NITROGEN TRIIODIDE: Here are some notes I took four years ago on how
|
|||
|
to make this wild explosive that can be detonated by a fly walking on it. Five

grams iodine, three grams potassium iodide, 20 ml. concentrated ammonium
|

|
hydroxide, filter paper, funnel. Stir the potassium iodide and iodine together
|
|||
|
in a beaker with 50 ml. of water. Add the ammonium hydroxide with stirring until
|
|||
|
no more precipitate forms. Filter and spread a thin layer of the wet solid on
|
|||
|
several filter papers. Break the filter papers into many small pieces and allow
|
|||
|
to dry for several hours. On drying, the paper is extremely sensitive to touch
|
|||
|
and will explode violently with the slightest disturbance. Can be handled safely
|
|||
|
when wet. Do not let any sizeable quantity of the dry material accumulate. --- I
|
|||
|
was able to buy concentrated ammonium hydroxide from a photographic supply.

HOW TO MAKE UREA NITRATE: Would you be offended if I asked you to go pee in a
|
|||
|
pot? Actually, this is the first step to making a powerful explosive called urea
|
|||
|
nitrate. Boil 10 cups of urine in a heat resistant glass container until the
|
|||
|
volume is reduced to 1 cup. Filter the urine into a second glass container
|
|||
|
through a coffee filter. Slowly add 133 cup of nitric acid to the filtered urine
|
|||
|
and let the mixture stand for 1 hour. Filter again as before. This time the urea
|
|||
|
nitrate crystals will collect on the filter. Wash the crystals by pouring water
|
|||
|
over them. Remove the crystals from the filter and allow to dry for 16 hours.
|
|||
|
This explosive has the disadvantage of requiring a blasting cap to detonate it,
|
|||
|
but I couldn't resist telling you about it.

The following message was an answer to a question from a user who knew the
|
|||
|
ingredients for nitroglycerin, but needed to know how much of each chemical to
|
|||
|
use:
|
|||
|
|
|||
|
For information only. *** By weight, one part of glycerin is nitrated with
|
|||
|
6 parts of mixed acid. The acid mixture is 40% Nitric and 60% Sulfuric. The
|
|||
|
Sulfuric acid is slowly added to the Nitric acid with constant stiring. Never
|
|||
|
mix them the other way round. Each part of glycerin will yield 2.3 parts of
|
|||
|
nitroglycerin. The temperature when adding the glycerin to the acids should
|
|||
|
never go above 25 degrees centigrade. If it does or if red fumes appear, the
|
|||
|
whole mess should be dumped into cold water fast. Do not take this as an
|
|||
|
encouragement to make nitroglycerin. You specifically asked me for the
|
|||
|
information and I have given it to you. What you do with it is your
|
|||
|
responsibility.

Because of its extreme popularity, this chapter would not be complete
|
|||
|
without a discussion of thermite. And so, by poplular demand, I present to you
|
|||
|
straight from the computer underground for a limited engagement:
|
|||
|
|
|||
|
HOW TO MAKE THERMITE
|
|||
|
|
|||
|
Thermite is made from powdered aluminum and iron oxide (rust). Mix two
|
|||
|
parts by volume powdered aluminum with three parts iron oxide. This stuff is
|
|||
|
hard to lite, but once you get it going, it generates so much heat it can burn
|
|||
|
its way through a steel plate.
|
|||
|
There are several ways to get it going. One way is to use a strip of
|
|||
|
magnesium ribbon as a fuse. If made from finely powdered ingredients thermite
|
|||
|
can generate a fast enough burning rate to be used as an explosive when
|
|||
|
confined. For melting metel, it is best to use a coarse mixture about the
|
|||
|
consistancy of ground coffee.
|
|||
|
Powdered aluminum can be bought at some paint stores or from a chemical
|
|||
|
supply. You can make your own iron oxide by burning steel wool in a stove pipe
|
|||
|
or similar container. Get it started with a propane torch and then blow a stream
|
|||
|
of air over it with a vacuum cleaner hooked up in reverse.
