Now the options are starting to open up!

The airbrush really looks like t would be an easy option.

I m not sure what im looking at with the last humidifier altho the plume looks very close.

The ultrasonics humidifiers use a piezoelectric cristal when works atomize water in little drops(make like fog). the cristal ever be cover by water in the first pics they use a porous material (white) to absorve some water to up side of cristal.

Other factor is the shape of outflow more or less narrow to adjust the plume.

Switch on off the current do the pulses effect. The usb humidifiers works to 5v. adjust the circuit and with some more power enhance the effect.

one example of usb humidifier video:

Hi I hope this helps it looks just like what you are after, although I am not sure you have this in the States?

This would be safer than any of the options listed already - some just sound like an explosion waiting to happen.

Welcome to MAGICOOL website

If you could rig it up so that the cans could be replaced you may have a winner.
 
I was thinking of using one or two of these to generate mist for in the Hellboy/BPRD "Johann Kraus" costume I am making for Halloween next year:

No real pressure behind the smoke, but it's safe... and looks pretty small. (Not to mention inexpensive.)
 
Hmm... I just found a similar product here. Disco smoke in a can! I'm gonna see if I can use that. Thanks for the tip! :thumbsup
