SMOKE BOMBS 4.14 -= Exodus =-
|
|
|
|
|
|
One type of pyrotechnic device that might be employed by a terrorist in
|
|
many way would be a smoke bomb. Such a device could conceal the getaway
|
|
route, or cause a diversion, or simply provide cover. Such a device, were it
|
|
to produce enough smoke that smelled bad enough, could force the evacuation of
|
|
a building, for example. Smoke bombs are not difficult to make. Although the
|
|
military smoke bombs employ powdered white phosphorus or titanium compounds,
|
|
such materials are usually unavailable to even the most well-equipped
|
|
terrorist. Instead, he/she would have to make the smoke bomb for themselves.
|
|
|
|
Most homemade smoke bombs usually employ some type of base powder, such
|
|
as black powder or pyrodex, to support combustion. The base material will
|
|
burn well, and provide heat to cause the other materials in the device to
|
|
burn, but not completely or cleanly. Table sugar, mixed with sulfur and a
|
|
base material, produces large amounts of smoke. Sawdust, especially if it has
|
|
a small amount of oil in it, and a base powder works well also. Other
|
|
excellent smoke ingredients are small pieces of rubber, finely ground
|
|
plastics, and many chemical mixtures. The material in road flares can be
|
|
mixed with sugar and sulfur and a base powder produces much smoke. Most of
|
|
the fuel-oxodizer mixtures, if the ratio is not correct, produce much smoke
|
|
when added to a base powder. The list of possibilities goes on and on. The
|
|
trick to a successful smoke bomb also lies in the container used. A plastic
|
|
cylinder works well, and contributes to the smoke produced. The hole in the
|
|
smoke bomb where the fuse enters must be large enough to allow the material to
|
|
burn without causing an explosion. This is another plus for plastic
|
|
containers, since they will melt and burn when the smoke material ignites,
|
|
producing an opening large enough to prevent an explosion.
|
|
|
|
--SIMPLE 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
|
|
|
|
6 pt. ZINC POWDER
|
|
1 pt. SULFUR POWDER
|
|
Insert a red hot wire into the pile, step back.

|
|
|
---COLORED FLAMES
|
|
|
|
Colored flames can often be used as a signaling device for terrorists. by
|
|
putting a ball of colored flame material in a rocket; the rocket, when the
|
|
ejection charge fires, will send out a burning colored ball. The materials that
|
|
produce the different colors of flames appear below.
