[SML] Ultrasonic low fog machines....

[Bruce Cooper]

I spent 9 years living with an LN2 fogger.  If you can afford one, and you can 
keep people trained on handling LN2, it is just about the BEST non-glycol, 
non-chemical fog system around.

  We used it for fog curtains, fog waves, creeping fog, sudden fog, 
directional fog..... We projected on it, we underlit it, boiled it out of 
openings and blew it high into the air. 

(Yes, people *still* coughed even though it was water vapor.)

  Tuning your airflow, Nitrogen volume, water temperature, water cycle speed, 
and a couple other variables changes the fog type, dwell, drift, and other 
qualities.

  Is it the be-all, end-all?  Certainly not.  But in 2 decades using every fog 
creation method I [and several others] have ever known, LN2 comes the closest 
to BAEA..

  Reminiscence and unintentional endorsement  concluded.  We now return you to 
your regularly scheduled 4 minute videos.....
