- Article #1: Explosives
- By Zaphod Beeblebrox/MPG
-
- This article deals with the instructions for creating some dangerous
- explosives. If you intend to make any of these explosives, do so in SMALL
- AMOUNTS ONLY, as they are all dangerous and could seriously injure or kill you
- if done in larger amounts. If you don't know anything about chemistry, DON'T DO
- THESE EXPERIMENTS! I am not joking in giving this warning. Unless you have a
- death wish, you shouldn't try any of the following unless you have had prior
- experience with chemicals.
- I am not responsible for any injury or damage caused by people using this
- information. It is provided for use by people knowledgable in chemistry who are
- interested in such experiments and can safely handle such experiments.
-
- ===============================================================================
-
-
- I. Common "weak" explosives.
-
- A. Gunpowder:
- 75% Potassium Nitrate
- 15% Charcoal
- 10% Sulfur
-
- The chemicals should be ground into a fine powder (seperately!) with a
- morter & pestle. If gunpowder is ignited in the open, it burns fiercely, but if
- in a closed space it builds up pressure from the released gases and can explode
- the container. Gunpowder works like this: the potassium nitrate oxidizes the
- charcoal and sulfur, which then burn fiercely. Carbon dioxide and sulfur
- dioxide are the gases released.
-
- B. Ammonal:
- Ammonal is a mixture of ammonium nitrate (a strong oxidizer) with aluminum
- powder (the 'fuel' in this case). I am not sure of the % composition for
- Ammonal, so you may want to experiment a little using small amounts.
-
- C. Chemically ignited explosives:
-
- 1. A mixture of 1 part potassium chlorate to 3 parts table sugar (sucrose)
- burns fiercely and brightly (similar to the burning of magnesium) when 1 drop
- of concentrated sulfuric acid is placed on it. What occurs is this: when the
- acid is added it reacts with the potassium chlorate to form chlorine dioxide,
- which explodes on formation, burning the sugar as well.
- 2. Using various chemicals, I have developed a mixture that works very well
- for imitating volcanic eruptions. I have given it the name 'MPG Volcanite'
- (tm). Here it is: potassium chlorate + potassium perchlorate + ammonium nitrate
- + ammonium dichromate + potassium nitrate + sugar + sulfur + iron filings +
- charcoal + zinc dust + some coloring agent. (scarlet= strontium nitrate,
- purple= iodine crystals, yellow= sodium chloride, crimson= calcium chloride,
- etc...).
- 3. So, do you think water puts out fires? In this one, it starts it. Mixture:
- ammonium nitrate + ammonium chloride + iodine + zinc dust. When a drop or two
- of water is added, the ammonium nitrate forms nitric acid which reacts with the
- zinc to produce hydrogen and heat. The heat vaporizes the iodine (giving off
- purple smoke) and the ammonium chloride (becomes purple when mixed with iodine
- vapor). It also may ignite the hydrogen and begin burning.
- Ammonium nitrate: 8 grams
- Ammonium choride: 1 gram
- Zinc dust: 8 grams
- Iodine crystals: 1 gram
- 4. Potassium permanganate + glycerine when mixed produces a purple-colored
- flame in 30 secs-1 min. Works best if the potassium permanganate is finely
- ground.
- 5. Calcium carbide + water releases acetylene gas (highly flammable gas used
- in blow torches...)
-
- II. Thermite reaction.
-
- The Thermite reaction is used in welding, because it generates molten iron
- and temperatures of 3500 C (6000F+). It uses one of the previous reactions that
- I talked about to START it!
-
- Starter=potassium chlorate + sugar
- Main pt.= iron (III) oxide + aluminum powder (325 mesh or finer)
-
- Put the potassium chlorare + sugar around and on top of the main pt. To
- start the reaction, place one drop of concentrated sulfuric acid on top of the
- starter mixture. STEP BACK! The ratios are: 3 parts iron(III) oxide to 1 part
- aluminum powder to 1 part potassium chlorate to 1 part sugar.
- When you first do it, try 3g:1g:1g:1g!
- Also, there is an alternative starter for the Thermite reaction. The
- alternative is potassium permanganate + glycerine. Amounts: 55g iron(III)
- oxide, 15g aluminum powder, 25g potassium permanganate, 6ml glycerine.
-
- III. Nitrogen-containing high explosives.
-
- A. Mercury(II) Fulminate
- To produce Mercury(II) Fulminate, a very sensitive shock explosive, one
- might assume that it could be formed by adding Fulminic acid to mercury. This
- is somewhat difficult since Fulminic acid is very unstable and cannot be
- purchased. I did some research and figured out a way to make it without
- fulminic acid. You add 2 parts nitric acid to 2 parts alcohol to 1 part
- mercury. This is theoretical (I have not yet tried it) so please, if you try
- this, do it in very* small amounts and tell me the results.
-
- B. Nitrogen Triiodide
- Nitrogen Triiodide is a very powerful and very shock sensitive explosive.
- Never store it and be carful when you're around it- sound, air movements, and
- other tiny things could set it off.
-
- Materials-
- 2-3g Iodine
- 15ml conc. ammonia
- 8 sheets filter paper
- 50ml beaker
- feather mounted on a two meter pole
- ear plugs
- tape
- spatula
- stirring rod
-
- Add 2-3g Iodine to 15ml ammonia in the 50ml beaker. Stir, let stand for 5
- minutes.
- DO THE FOLLOWING WITHIN 5 MINUTES!
- Retain the solid, decant the liquid (pour off the liquid but keep the brown
- solid...). Scape the brown residue of Nitrogen Triiodide onto a stack of four
- sheets of filter paper. Divide solid into four parts, putting each on a
- seperate sheet of dry filter paper. Tape in position, leave to dry undisturbed
- for AT LEAST 30 minutes (preferrably longer). To detonate, touch with feather.
- (WEAR EAR PLUGS WHEN DETONATING OR COVER EARS- IT IS VERY LOUD!)
-
- C. Cellulose Nitrate (Guncotton)
-
- Commonly known as Smokeless powder, Nitrocellulose is exactly that- it
- does not give off smoke when it burns.
-
- Materials-
- 70ml concentrated sulfuric acid
- 30ml concentrated nitric acid
- 5g absorbent cotton
- 250ml 1M sodium bicarbonate
- 250ml beaker
- ice bath
- tongs
- paper towels
-
- Place 250ml beaker in the ice bath, add 70ml sulfuric acid, 30 ml nitric
- acid. Divide cotton into .7g pieces. With tongs, immerse each piece in the acid
- solution for 1 minute. Next, rinse each piece in 3 successive baths of 500ml
- water. Use fresh water for each piece. Then immerse in 250ml 1M sodium
- bicarbonate. If it bubbles, rinse in water once more until no bubbling occurs.
- Squeeze dry and spread on paper towels to dry overnight.
-
-
- D. Nitroglycerine
-
- Nitroglycerine is a *VERY* dangerous shock sensitive explosive. It is used
- in making dynamite, among other things.
- I am not sure as to the proportions and amounts of chemicals to be used, so
- I shall use estimates.
-
- Materials-
- 70ml conc. sulfuric acid
- 30ml conc. nitric acid
- 10 ml glycerine
- ice bath
- 150ml beaker
-
- Put the 150ml beaker in the ice bath and make sure that it is very cold.
- Slowly add the 70ml sulfuric and 30ml nitric acids to the beaker, trying to
- maintain a low temperature. When the temperature starts to level off, add about
- 10ml glycerine. If it turns brown or looks funny, **RUN LIKE HELL**. When
- Nitroglycerine turns brown, that means it's ready to explode... If it stays
- clear and all works well, keep the temperature as low as you can and let it sit
- for a few hours. You then should have some Nitroglycerine, probably mixed with
- nitric and sulfuric acids. When you set it off, you must not be nearby.
- Nitroglycerine can fill 10,000 times its original area with expanding gases.
- This means that if you have 10ml's of Nitroglycerine in there, it will produce
- some 100,000ml's of gases.
- To make it into dynamite, the Nitroglycerine must be absorbed into something
- like wood pulp or diamaeceous earth (spelled something like that).
-
-
- IV. Other stuff
-
- A. Peroxyacetone
-
- Peroxyacetone is extremely flammable and has been reported to be shock
- sensitive.
-
- Materials-
- 4ml Acetone
- 4ml 30% Hydrogen Peroxide
- 4 drops conc. hydrochloric acid
- 150mm test tube
-
- Add 4ml acetone and 4ml hydrogen peroxide to the test tube. Then add 4 drops
- concentrated hydrochloric acid. In 10-20 minutes a white solid should begin to
- appear. If no change is observed, warm the test tube in a water bath at 40
- celsius. Allow the reaction to continue for two hours. Swirl the slurry and
- filter it. Leave out on filter paper to dry for at least two hours. To ignite,
- light a candle tied to a meter stick and light it (while staying at least a
- meter away).
-
- B. Smoke smoke smoke...
-
- The following reaction should produce a fair amount of smoke. Since this
- reaction is not all that dangerous you can use larger amounts if necessary for
- larger amounts of smoke.
-
- 6g zinc powder
- 1g sulfur powder
-
- Insert a red hot wire into the pile, step back. A lot of smoke should be
- created.
-
-
-
-
- There are many other experiments I could have included, but I will save them
- for the next Chemist's Corner article. Upcoming articles will include
- Glow-in-the-dark reactions, 'party' reactions, things you can do with household
- chemicals, and more...
-
- I would like to give credit to a book by Shakashari entitled "Chemical
- Demonstrations" for a few of the precise amounts of chemicals in some
- experiments.
-
-
- This is it for Chemist's Corner #1... look for Chemist's Corner #2: What to do
- with household chemicals...
