                                Pyrotechnics #2


      Touch Paper, Self Igniting Mixtures, Percussion Explosives


Sodium Azide - NaN
                  3
This white powder is very poisonous. It is also a bit unstable, so treat it
gently.

Lead Nitrate - Pb(NO )
                    3 2
This contains poisonous lead and is very water soluble so your body will
absorb it quickly, given the chance. The government has banned leaded paints
and is phasing out leaded gasoline because the stuff slowly accumulates in
your body and can screw up all sorts of important innards. If you are careless
with Lead Nitrate you can do a few lifetimes' worth of damage in one
afternoon.

Ammonium Nitrate - NH NO
                     4  3
Commonly used as fertilizer, this stuff is somewhat dangerous in large
quantities, particularly if it gets very hot. (Entire shiploads of this
material have been known to go up all at once.) When heated gently, it
decomposes into water and nitrous oxide (laughing gas). Farmers sometimes use
it to blow up tree stumps by mixing it with fuel oil and setting the gunk off
with a detonator. We'll have a very different use for it here.

Potassium Nitrate - KNO
                       3
Also known as saltpeter, this is commercially used as a diuretic for animals.
It also works as an oxidizing agent in various pyrotechnic mixtures. That is,
when heated it provides the oxygen needed to make the rest of the mixture
burn.

Potassium   Potassium
 Nitrate     Nitrite   Oxygen

 2KNO   --->  2KNO    +  O
     3            2       2



Potassium Chlorate - KClO
                         3
A much more spectacular oxidizing agent than Potassium Nitrate. It not only
yields more oxygen than Potassium Nitrate, it does so more easily. Pyrotechnic
mixtures containing this chemical will require much less of it, and yet burn
more fiercely. Even percussion can readily set the mixtures off. This can be
useful, but it sometimes makes the mixtures more sensitive than you'd like.
Mixtures containing this chemical must be handled carefully. Potassium
Chlorate is also poisonous.

Potassium     Potassium
 Chlorate      Chloride   Oxygen

  2KClO   --->   2KCl   +   3O
       3                      2


Aluminum Dust

Very finely divided aluminum. When put in a glass jar, it almost looks like a
solid piece of grey metal. In this form it is flammable. Also, it can
seriously damage your lungs if you inhale it. Be careful not to stir up any
clouds of dust, and it goes without saying that you shouldn't use it near an
open flame.

Zinc Dust

Very finely divided zinc. Not quite as flammable as Aluminum Dust, but still
worth handling carefully. Can also damage your lungs if inhaled.

Lampblack

This is very finely divided carbon, usually obtained as a soot from other
manufacturing processes. It is much more effective in pyrotechnic mixtures
than powdered charcoal. Tiny spots of this are almost unnoticeable, but they
stick to your hands and smear incredibly far. If you're not very tidy you
should expect to find black smears all over your face and hands after using
this.

Sulfur

A yellow powder used as a reducing agent in many pyrotechnic mixtures. Buy
this in the finely powdered form. You can also get it in hard lumps, but these
will just waste extra time as you have to grind them yourself.

Potassium Permanganate

An oxidizing agent that's somewhat less vigorous than others mentioned here.
Not usually used in pyrotechnic mixtures because it's more expensive and less
effective than some of the alternatives. There are a few cases when it's just
the right thing. Don't let this accidentally come in contact with glycerine.
If such an accident happens, the resulting mess should be immediately wiped up
with wet paper towels and buried or flushed down a toilet. It should NOT be
thrown away in a dry waste receptacle!!!

Gum Arabic

A white powder which is mixed with water to make a glue like substance. Useful
for coating various mixtures or binding them together into a solid mass.

Sodium Peroxide

A very strange and dangerous oxidizer. Don't let it get wet and don't let it
touch your skin.

Glycerine

A thick liquid, chemically similar to rubbing alcohol. Though harder to get
burning, it will burn in the right circumstances. Fairly safe stuff.

Iodine Crystals

Pure Iodine is a steel grey solid, which is poisonous and which produses
poisonous vapors when heated. Smells similar to the chlorine used in bleaches
and swimming pools. If you accidentally should drop some on a hot surface and
notice the odor, you should leave the area.



                                Touch Paper

  This is an easily made material that acts like a slow burning fuse and is
ideal for testing small amounts of a pyrotechnic mixture. It is made by
soaking a piece of absorbent paper, like a paper towel, in a saturated
solution of Potassium Nitrate. (A saturated solution means that you have
dissolved as much of the chemical in water as is possible.) Hang the paper up
to dry, and be sure to wipe up any drips. When dry it is ready. Cut off a
small strip and light the edge to see how different it acts from ordinary
paper. This will ignite all but the most stubborn mixtures, and will ignite
gunpowder, which will in turn ignite most anything else.

  Don't dip the towel in the Potassium Nitrate solution a second time to try to
make it "stronger". This will actually make it less effective. Some of the
fancier paper towels don't work too well for this. Best results are obtained
from the cheap folded paper towels found in public restrooms everywhere.


                           Self Igniting Mixtures

  Pulverize 1 gram of Potassium Permanganate crystals and place them on an
asbestos board or in an earthenware vessel. Let 2-3 drops of glycerine fall
onto the Potassium Permanganate. The mixture will eventually sizzle and then
flare. Potassium Permanganate is the oxidizing agent. The glycerine is
oxidized so quickly that heat is generated faster than it can be dissipated.
Consequently, the glycerine is ignited. Because this mixture takes so long to
catch on fire, it is sometimes useful when a time delay is needed to set off
some other mixture. If you lose patience with this test, DO NOT THROW THE
MIXTURE AWAY IN A WASTEBASKET!!! Either bury it or flush it down a toilet. I
know of at least one house fire that was started because this was not done.
Given time, this stuff WILL start to burn.

  This demonstration produces a very nice effect, but sends out a lot of
poisonous fumes, so do it outside. Make a mound of equal volumes of iodine
crystals and aluminum dust. Make a small indentation at the top of the mound
and add a drop or two of water and move away. It will hiss and burst into
flame, generating thick purple smoke. The fumes are Iodine vapor which is
very caustic, so make sure you are upwind of the fire. Since this is set off
by moisture, you should not store the mixed material. Mix it immediately
before you plan to use it.

  Shred a small piece of newspaper and place on it a small amount of sodium
peroxide. Add two drops of hot water. The paper will be ignited. CAUTION: Keep
Sodium Peroxide from moisture and out of contact with organic materials (your
skin, for example.)

  Ammonium Nitrate, 5 grams, 1 gram of Ammonium Chloride. Grind these
SEPARATELY, and add 1/4 gram of zinc dust. Form a cone and add 2-4 drops of
water. A bright blue flame with large volumes of smoke forms. Depending on the
quality of your zinc dust, you may need to increase the quantity of zinc.
Since this is ignited by moisture, you should not attempt to store this
mixture.


                           Percussion Explosives

  This section will not only introduce a couple of mixtures with interesting
possibilities, but it will also demonstrate how sensitive mixtures containing
Potassium Chlorate can be. Keep in mind that Chlorate mixtures can be a LOT
more sensitive than the ones shown here.


  Mix 1 part by weight of Sulfur, and 3 parts Potassium Chlorate. Each should
be ground separately in a mortar. They should be mixed lightly without any
pressure on a sheet of paper. A small amount of this mixture (less than one
gram!!) placed on a hard surface and struck with a hammer will explode with a
loud report.

  Mix the following parts by weight, the same way as above,

                Potassium Chlorate 6
                Lampblack          4
                Sulfur             1

  Both of these mixtures are flammable. Mix small quantities only.



                             Lead Azide  Pb(N )
                                             3 2

  Unlike many explosives that must be enclosed in a casing to explode, and
others that require a detonator to set them off, Lead Azide will explode in
open air, either due to heat or percussion. Mixed with gum arabic glue, tiny
dots of it are placed under match heads to make trick exploding matches. The
same mixture coated onto 1/2 " wood splinters are used to "load" cigars. In
larger amounts, it is used as a detonator. A moderately light tap will set it
off, making it much more sensitive than the percussion explosives already
mentioned. It is very easy to make.

  Take about 1.3 grams of sodium azide and dissolve it in water. It's best not
to use any more water than necessary. In a separate container, dissolve about
3.3 grams of Lead Nitrate, again only using as much water as needed to get it
to dissolve. When the two clear liquids are mixed, a white precipitate of Lead
Azide will settle out of the mixture. Add the Lead Nitrate solution, while
stirring, until no more Lead  Azide precipitates out. You may not need to use
it all. Note that the above weights are given only for your convenience if you
have the necessary scales, and give the approximate proportions needed. You
need only continue to mix the solutions until no more precipitate forms.

  The precipitate is filtered out and rinsed several times with distilled
water.  It is a good idea to store this in its wet form, as it is less
sensitive this way. It's best not to store it if possible, but if you do, you
should keep it in a flexible plastic container that wont produce sharp
fragments in case of an explosion. (NO MORE THAN A GRAM AT A TIME !!!!) Also,
make sure that the mouth of the container is wiped CLEAN before putting the lid
on. Just the shock of removing the lid is enough to set off the dry powder if
it is wedged between the container and the stopper. Don't forget that after
you've removed the precipitate from the filter paper, there will still be
enough left to make the filter paper explosive.

  Lead Azide is very powerful as well as very sensitive. Never make more than a
couple of grams at one time.

            Reaction Equations

Lead        Sodium        Lead     Sodium
Nitrate      Azide       Azide    Nitrate

Pb(NO )   +  2NaN   ---> Pb(N )  + 2NaNO
     3 2         3           3 2        3

  Don't try to salvage the Sodium Nitrate that's left over (dissolved in the
water). Sodium nitrate is cheap, not really useful for good pyrotechnics, and
this batch will be contaminated with poisonous lead. It's worthless stuff.
Dump it out.

  To demonstrate the power of a little bit of Lead Azide, cut out a piece of
touch paper in the following shape



-----------------------------
!                            !
!                            !

-----------------------------

  Where the size of the wide rectangle is no more than one inch x 1/2 inch, and
the length of the little fuse is at least 3/4 inch. Apply a thin layer of wet
Lead Azide to the large rectangle with a paint brush and let it dry
thoroughly. When done, set this tester out in the open, light the fuse at the
very tip and step back. If done properly, the tiny bit of white powder will
produce a fairly loud explosion.


                          A Lead Azide Booby Trap

  Get some string that's heavy enough so that it won't break when jerked hard.
A couple of feet is enough to test this out. You may want to use a longer piece
depending on what you plan to do with this. Fold a small "Z" shape in the
center of the string, as shown in figure 1. The middle section of the "Z"
should be about one inch long.


-------------------------------------.
                             .

           .
       --------------------------------------------------

                  Figure 1. Fold string into a small Z

  Next, twist the Z portion together as tightly as you can. Don't worry if it
unwinds a bit when you let go, but it should still stay twisted closely
together. If it doesn't, you will need a different kind of string. Figure 2
tries to show what this will look like.

-------------//////////////////-----------------

                  Figure 2. Twist the Z portion tightly

  Next, apply some wet Lead Azide to the twisted portion with a paint brush.
The Lead Azide should have a bit of Gum Arabic in it to make it sticky. Cut
out a piece of paper, two inches by 6 inches long, wrap it around the twisted
portion, and glue the end on so that it stays put. You should now have a two
inch narrow paper tube with a string sticking out each end, as shown in figure
3.

          -------------------------
          !                       !
----------!                       !-------------------
          !                       !
          -------------------------

                  Figure 3. The completed Booby Trap

  You should now set the booby trap aside for at least two weeks so that the
Lead Azide inside can dry completely. Don't try to speed up the process by
heating it. When the two ends of the string are jerked hard, the friction in
the wound up string will set off the Lead Azide. The booby trap can be
attatched to doors, strung out as tripwires, or set up in any other situation
that will cause a quick pull on the strings. Be careful not to use too much
Lead Azide. A little will go a long way. Before trying this on an unsuspecting
soul, make a test booby trap as explained here, tie one end to a long rope,
and set it off from a distance.

  The paper wound around the booby trap serves two purposes. It keeps the Lead
Azide from flaking off, and it pads the stuff so it will be less likely to get
set off accidentally. A good vigorous swat will still set it off though, so
store these separately and keep them padded well.


                          Getting The Chemicals

  As always, be sure to use your brains when ordering chemicals from a lab
supply house. Those people KNOW what Sodium Azide and Lead Nitrate make when
mixed together. They also know that someone who orders a bunch of chlorates,
nitrates, metal dusts, sulfur, and the like, probably has mischeif in mind,
and they keep records. So break your orders up, order from different supply
houses, get some friends to order some of the materials, and try to order the
things long before you plan do do anything with them. It's a pain, and the
multiple orders cost a lot in extra shipping charges, but that's what it costs
to cover your tracks. DO it!
