Flash
Pots & Pans
Last
week, I compared some of the essential components of pyrotechnic
effects with the staple ingredients found in any good kitchen. As
I thought more about that analogy, I realized that even the best-stocked
kitchen is useless without something in which to prepare the ingredients.
The same, of course, holds true for special effects. Just as a good
cook needs a few good pots and pans to prepare a meal, so too does
a special effects technician need the proper hardware to prepare
his effects.
The most basic and essential piece of hardware in any technician's
kit is the flash pot. Flash pots come in a variety of styles, but
all feature the same two basic components a "pot" or chamber
to hold the powder, and some means of delivering a spark or flame
to that powder. Old home-made pots were often nothing more than
a coffee can with a large fuse in the bottom. Powder was placed
inside the fuse and when current was applied the fuse would blow,
delivering a spark to ignite the powder. While this type of pot
may still be found in some places today, the availability of inexpensive,
quality hardware coupled with the increased vigilance of fire and
safety inspectors has caused a steady decline in "do it yourself"
pyrotechnic equipment.
Theatre Effects offers several different flash pots of varying styles
and prices. While they all do the same basic job, each has specific
applications in which it shines above the rest. The pot you choose
will be determined by the demands of your show and your budget.
This week, I'd like to focus specifically on the Electronic Flash
Pot featured in the weekly special.
The Electronic Flash Pot was designed for performers who want to
create a flash effect on stage but don't want the bother of running
cables and finding an operator to run the effects. Basically, the
flash pot and firing controller are combined into one device. A
six-foot control cord is wired onto the flash pot, with a simple
footswitch attached. Power is provided to the device from two "AA"
batteries. With this set-up, all a performer need do is place the
pot on stage, locate the footswitch in a convenient spot, and load
the pot. No technician to fire the pot (or miss a cue) and no running
power cables off stage.
Because the Electronic Flash Pot uses "AA" batteries instead
of line voltage for its power, it cannot fire standard igniters.
Instead, this pot has a glo-plug -- basically a miniature heating
coil -- that can ignite Flash Cotton. The Flash Cotton acts as a
fuse, burning into the powder and setting off the effect. The glo-plug
is a reusable device, but it will need to be replaced every 20 -
30 shots; for this reason, we generally recommend buying a spare
glo-plug when you purchase your pot.
The Electronic Flash Pot can fire almost every powder that Theatre
Effects carries, except for Sonic Flash Powder. Sonic Powder is
a powerful, fast-burning powder that creates a loud report when
fired. Because of the force with which Sonic Powder combusts, it
should only be fired in the Ultra Color Volcano, a flash pot designed
for loud report effects. Powders that do work in the Electronic
Flash Pot include White, Photo, Red and Green Flash Powder, and
Smoke Powder, which is available in a wide range of colors. Additionally,
Electric Sparkle Additive can be added to Flash Powder to add crackling
silver sparks to the flash effect.
Finally, we've had some inquiries about increasing the length of
the control cord on the Electronic Flash Pot. Simply put, we don't
offer a longer cord, and it's not a great idea to do it yourself.
We use a six-foot cord because it allows the operator to be at a
safe distance from the effect without causing a drop in voltage
to the glo-plug. When you increase the length of the cord, you increase
the resistance in the system, causing the voltage to drop. It doesn't
take a big drop in voltage to cause the glo-plug to stop working
-- remember, you only have 3 volts to begin with! If you find that
you want to have a performer on one side of the stage while the
effect goes off on the other, you probably should consider the Standard
Electric Flash Pot, or the Ultra Flash Pot, both of which use line
voltage and can be plugged into extension cables of almost any length.
The Flash Pot you choose will be a reflection of what you as a performer
or technician need and expect from your special effects. While money
will always be a factor in any purchasing decision, it should almost
never be the deciding one. Take time to determine what you plan
to do with your special effects now, and over the next year. With
that knowledge, and a little help from your friends at Theatre Effects,
you should be able to pick the device that is best suited to your
needs.
