I Borrow A Cup Of Flash Powder?
Webster's
Collegiate Dictionary defines a staple as "a commodity for
which the demand is constant; something having widespread and constant
use or appeal." In our parents' and grandparents' time, staple
ingredients included butter, milk, salt, sugar, eggs, flour and
baking powder. These were the basic ingredients assumed to be present
in any well-stocked kitchen, and sometimes the only ingredients
found in poor kitchens. Today's homemakers might consider microwave
burritos, Diet Pepsi and pudding cups as staples -- I know I do!
However, the fact remains that anyone hoping to actually cook a
meal will probably need at least one of the staples.
In the special effects industry, we have staple ingredients, as
well. These products are used on a regular basis to create any number
of effects, from flashes of fire to clouds of smoke. While the "spices"
(color and sparkle additives) may vary from shot to shot, these
ingredients will always be in demand. Let's take a look at some
of the staples you might find in a pyrotechnician's kit flash
paper is one of the most basic -- and most versatile -- ingredients
for creating special effects. It can be used by itself and lit with
a match or cigarette to create a quick flame effect; or it can be
used to hold pyrotechnic powders such as flash
powder for airburst effects or sparkle
additive for a burst of flame with crackling sparks. Flash paper
can also be used as a primer, ensuring that all of the powder in
a flash
pot burns evenly. When flash paper is burned in a confined space
(such as the barrel of a flash
gun or confetti
launcher) the gasses produced act as a propellant for the flash
paper itself and, sometimes, for the confetti
or streamers loaded on top of it. In addition to its many uses,
flash paper is also a relatively cool-burning product that produces
no smoke or fallout, and is available in a wide range of sizes and
colors.
Flash
cotton is similar to flash paper in many respects, which isn't
surprising when you consider that they're just different forms of
the same material (nitrocellulose). The light, fluffy form of flash
cotton, however, means that it is much more volatile than flash
paper and burns at a quicker rate. This makes flash cotton an excellent
choice as a primer in devices that use a glo-plug
or spark
wheel for ignition, since the cotton will ignite at a lower
temperature than even flash paper. In addition to this, flash cotton
can be coated with sparkle additive to create a burst of sparks
with little visible flame, or it can be used by itself to create
a small, instant flash of fire in devices such as the Flint
Flasher or Thumb
Thing.
Flash powder is the primary ingredient in any effect calling for
an instantaneous puff of smoke. Because of its volatility, and the
force with which it burns, flash powder is almost always used in
a flash pot -- and is *never* used in a handheld effect. Flash powder
is often used on its own to create a quick burst of light and cloud
of smoke; but it can also be used with sparkle additive to create
a giant burst of sparks. The flash of light produced by flash powder
can be white (the most popular) red
or green. There is also a sonic
flash powder available that produces loud reports when it's
fired in an appropriate pot.
Colored
smoke powder is a much slower burning effect than flash powder,
but it produces thick clouds of smoke in a wide range of colors.
The smoke from flash powder, even colored flash powder, is always
white. Because smoke powder is less volatile than flash powder and
has no fallout, it can be used in effects that occur at close range
to an actor. This makes it perfect for (dis)appearances, magical
lamps and malfunctioning machinery.
All of these powders and papers are pretty unimpressive until they
actually start burning, which is why any well-stocked pyro kit will
contain a variety of igniters.
The Surefire
electric match is one of our most popular igniters, it can be
used in any of our flash pots for igniting flash powder and colored
smoke powders, or it can be fired by itself to create a miniature
firecracker effect. Because the electric match combines a piece
of nichrome wire with a pyro compound, it will fire at a lower voltage
than the standard Surefire
igniter or bare
nichrome wire, making it ideal for effects using a low-voltage
power supply.
Just as every kitchen has its unique assortment of herbs, spices
and favorite ingredients, so too will every pyrotechnician's kit
contain a mix of color and sparkle additives, igniters and flash
devices. However, these products truly are the staples of a good
pyro kit. Try working without them for very long and you'll soon
find yourself over at the theatre next door, cup in hand.
