Dumping Terrorist's handbook
Buying Explosives and Propellants
Almost any city or town of reasonable size has a gun store and a pharmacy. These are two of the places that potential terrorists visit in order to purchase explosive material. All that one has to do is know something about the non-explosive uses of the materials. Black powder, for example, is used in blackpowder firearms. It comes in varying "grades", with each different grade being a slightly different size. The grade of black powder depends on what the calibre of the gun that it is used in; a fine grade of powder could burn too fast in the wrong caliber weapon. The rule is: the smaller the grade, the faster the burn rate of the powder.
Explosives
Black Powder
Black powder is generally available in three grades. As stated before, the smaller the grade, the faster the powder burns. Burn rate is extremely important in bombs. Since an explosion is a rapid increase of gas volume in a confined environment, to make an explosion, a quick-burning powder is desirable. The three common grades of black powder are listed below, along with the usual bore width (calibre) of what they are used in. Generally, the fastest burning powder, the FFF grade is desirable. However, the other grades and uses are listed below: GRADE BORE WIDTH EXAMPLE OF GUN F .50 or greater model cannon; some rifles FF .36 - .50 large pistols; small rifles FFF .36 or smaller pistols; derringers
The FFF grade is the fastest burning, because the smaller grade has more surface area or burning surface exposed to the flame front. The larger grades also have uses which will be discussed later. The price range of black powder, per pound, is about $8.50 - $9.00. The price is not affected by the grade, and so one saves oneself time and work if one buys the finer grade of powder. The major problems with black powder are that it can be ignited accidentally by static electricity, and that it has a tendency to absorb moisture from the air. To safely crush it, a bomber would use a plastic spoon and a wooden salad bowl. Taking a small pile at a time, he or she would apply pressure to the powder through the spoon and rub it in a series of strokes or circles, but not too hard. It is fine enough to use when it is about as fine as flour. The fineness, however, is dependant on what type of device one wishes to make; obviously, it would be impracticle to crush enough powder to fill a 1 foot by 4 inch radius pipe. Anyone can purchase black powder, since anyone can own black powder firearms in America.
Pyrodex
Pyrodex is a synthetic powder that is used like black powder. It comes in the same grades, but it is more expensive per pound. However, a one pound container of pyrodex contains more material by volume than a pound of black powder. It is much easier to crush to a very fine powder than black powder, and it is considerably safer and more reliable. This is because it will not be set off by static electricity, as black can be, and it is less inclined to absorb moisture. It costs about $10.00 per pound. It can be crushed in the same manner as black powder, or it can be dissolved in boiling water and dried.
