One of the Directors I work with is a fan of dropping all sorts of things. In Death of a Salesman it was leaves. In the Seagull it was flower petals. I built 3 little machines that have worked for dropping both of thes as well as snow flakes. I don't have the drawing here at home, I'll check the 'puter at work tomorrow. The boxes I built were for a relativly tight area, but I think you could modify them to
cover a larger one. 'course you could just
build a
chicken wire snow machine too.
As far as coverage, well that's really up to the look you want while falling, and the
build up you want on the floor. I wish I had found you resource for individual petal, I had to buy tons of silk flowers and take them apart.
Standard cautions for effects such as this;
Normally I never reccomend reusing anything you have dropped. this is especially true for snow as the plastic bits tend to
pick up a ton of dust through static. I have found that flower petals can be re-used but it is very important that you throughly "clean" them between uses. it's imperative that you clean any and all dust/dirt/
stage floor detrius off the petals for the
safety of you actors eyes. I've found putting the petals in a 5 gallon bucket and blowing a lot of air into them is an effective process, or just have a good old threshing party on a clean
drop cloth in the shop. Another important
safety tip is "watch where you
drop". If this is for a dance company You really need to be careful not to dop the petal directly on the dancers as silk petal
build up on the
stage floor can be really slick.
Hope that helps a
bit. I'll see if I have some drawing of my little machines at work and post them tomorrow.
