Let
It Snow!
Simulated
snow is a special effect that has been with us, in one form or another,
for many years now. Plays such as A Christmas Carol, ballets like
The Nutcracker, and all those holiday pageants and concerts generally
call for snow at least once during the performance. The classic
method for producing snow on stage was to use artificial white "flakes"
of confetti or shredded plastic. These flakes were dropped from
above the stage falling gently to the floor and creating the desired
effect.
Creating
snow in this way, however, presented some inconveniences. First,
because the "snow" in this case is really a paper or plastic
product it lacks one important aspect of real snow it doesn't melt!
This is only a minor inconvenience if the snow is falling behind
an upstage window, or if the "snowstorm" happens immediately
prior to an intermission. In these cases, the stage crew can remove
the snow after the show, or while the curtain is down. The non-melting
aspect of paper or plastic "snow" can also come back to
haunt the next production to use the theatre. Many technicians can
tell stories of artificial snow drifting gently to the stage floor
weeks, even months after the holiday show has closed.
Snow
machines were created to provide snow that looks and behaves more
like the real thing. Using a special fluid, the snow machine creates
thousands of realistic "flakes" that are really a water-based
foam. The water content in the foam is kept very low so that the
snow evaporates within seconds of touching the floor, leaving no
residue behind. This aspect alone has made snow machines incredibly
popular for performances where having confetti or plastic flakes
on the stage - or, for that matter, in the audience - is not desirable.
Dance companies, who try to avoid having anything on the floor that
might cause their performers to slip, stumble or fall, love the
fact that they can have a realistic snow effect without the worry
of anything under their dancers' feet. Rock 'n' roll bands and other
entertainers have started making use of snow machines to create
blizzards over the audience without having to pay exorbitant cleanup
fees to the venue's management. Because the snowflakes that the
machine creates are mostly air, they behave more like real snow
as they fall. Lighter than plastic or even tissue paper, the foam
flakes fall more slowly and can be blown across the stage by mounting
a fan under the machine. Care should be taken when adding a fan
to a snow effect, however, as blowing the snow too far may cause
it to evaporate before it reaches the stage floor. For most effects,
the blower built into the machine will provide adequate coverage.
Let's
talk a bit about coverage, and getting the most out of your snow
effect. The thing to remember when creating a snow effect on stage
is that it doesn't need to snow over the entire set. Usually, a
"curtain" of snow along the front of the scene is enough.
Without a fan, one machine will create a "cone" pattern
of snow that is about 15' wide by about 20' long. This coverage
is more than enough for most small stages. For larger stages (proscenium
width of 40' or more) two machines can be placed at opposite ends
of the stage and fans added if needed.
When
using two or more machines together, it's a good idea to make use
of the daisy-chaining feature of the BM60, BM70 and BM80 Snow Machines.
If you are using a DMX-compatible control console you can simply
address all the machines alike, thus allowing you to control them
all simultaneously. By controlling multiple machines from one remote
or control console, you can guarantee that the output volume on
all machines will be equal, resulting in an even distribution of
the snow. Also, linking the machines together means that you can
assign one crew member to "snow duty" instead of two or
more. This not only saves on crew costs, but can keep errors during
performance to a minimum.
