This was making the rounds on email yesterday: The Pure Smoke system by Jason Brumbalow. Say you need a clothes iron or a tea kettle to make steam on stage, but generating that kind of heat is too dangerous for the actors. You can probably hide one of these somewhere and let it make some room-temperature theatrical fog for you.
It essentially works like an e-cigarette with a nicotine-free cartridge. The major difference is you cue the vapor with a squeezable trigger rather than an airflow sensor which is activated when you inhale on the end. The vapor is generated from propylene glycol, which is among the safer kinds of chemicals used in theatrical foggers and electronic cigarettes.[ref]The amount of vapor produced by the Pure Smoke in the video looks to be extremely small, but if you are interested in the possible health risks of inhaling propylene glycol,Â especially in the quantities produced by full-stage theatrical foggers, I urge you to check this fact sheet aboutÂ propylene glycol from Monona Rossol, the leading expert on chemical hazards in the entertainment industry.[/ref]
The website lists the system at $147, with refill smoke packs starting at around $25. It says each cartridge gives you over 80 large “puffs”, with a refill pack giving you 10 cartridges, so that’s about 3 cents per puff. The cost is a great deal cheaper than palm-sized theatrical foggers ($1850), though I’d imagine the vapor is considerably less dense and long-lasting.
It has a battery pack which takes 4 AA batteries (not included) which is connected through a long wire to a squeezable trigger mechanism. The mechanism is rigged to be strapped to a performer’s chest, though I imagine you can alter it to fit any prop you need the smoke in. A hose runs from the mechanism to the dispenser tip, which also holds the smoke cartridge. The dispenser is about 3 1/2″ long; the diameter of the base is about half an inch, and the tip is a quarter of an inch.
