I'm making a mask, sort of a gas mask, but with a bunch of special effects. I plan to have some breathing vents (that you don't actually breath through), and if possible I would like to have fog issuing from them. I've done a few Google searches, but everything I've found has been really big or thousands of dollars. What do you suggest?
If all else fails, I can probably make some sort of compartment for dry ice.
