How could I build a mask that can breath out fog?
I am wondering if there is a way to make a mask with some sort of built in 'fog machine' of sorts. A way that I can breath out a fog like vapor from the mouth of the mask that is safe to breath in.
I intend on making the mouth of the mask able to open and close by attaching the bottom jaw to my jaw to allow it to open when my mouth opens and close when it closes.
I already fairly certain that dry-ice is entirely out of the equation as breathing in the vapors produced can be harmful.
