Some C02 extinguishers also shoot out flakes of "dry ice", looking much like
very heavy, large snowflakes. I have a 35lb (15 lbs of CO2) extinguisher that
I have discharged many times to produce "smoke" for photographing vehicles,
etc. The "snow" shoots out about 10-15 feet and is very unlikely to blow away
as a gas would.

I've never put out a fire with it. Knock on wood.
