C-4
This
is the standard-issue plastic explosive used by the U.S. military.
I recieved most of my early demo training in the army, which
spoiled me for C-4. It retains its moldability over a wider
range of temperatures, doesn't exude liquid (as does Semtex),
and is pound-for-pound the most powerful explosive in common
use. Its power, stability, and versatility are un- equalled.
C-4 is in such demand and so well thought of that Muammar
al- Quaddafi paid Edwin Wilson an exorbitant sum for 20 tons,
even though he could get all of the Semtex he wanted on the
open market for a much-lower price.
With
a few simple modifications, C-4 becomes even more versatile.
If you mix 7 fluid ounces of mineral oil with a 1 1/4 pound
bar, you get an exc- ellent paste explosive, roughly equivalent
in power to TNT, and capable of sticking to almost anything.
Sealed inside flat plastic bags, this mix can secreted in
any number of useful spots (softsided luggage, for instance).
One note of caution should be mentioned. With C-4 or any plastic
explo- sive, the user should avoid mashing it when loading
it into special devices or preparing charges. The sectional
density of an explosive has a direct bearing on its power
and velocity. The explosive packages are press-loaded to their
optimum density for highest performance. This it not to say
that they will not explode when used in this manner, but they
will not utilize their full explosive potential.
Sometimes
commercial number 8 blasting caps will not detonate C-4, which
was formulated for use with the more powerful J-2 military
caps. In this case, two number 8s can be taped together, or
some of its RDX can be extr- acted to use as a booster. To
do this, a small lump (about 1 ounce) of C-4 is put into a
cup of gasoline. The lump can be broken apart with a fork.
Let it sit for an hour or so. The RDX should have separated
from the plastic, which is soluble in gasoline, to form a
white powder at the bottom of the container. This residue
is filtered out of the gasoline and washed on the filter with
a little more gas. Letting it sit overnight will evaporate
any residual gas. Find a tube that will snugly fit the balsting
cap and hammer one end closed. One or two grams of the RDX
is pressed into the bottom of the tube, and the blasting cap
is inserted and taped into place.
