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. By controlling multiple
machines from one remote, 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.
