Mind, there's a good chance what you've seen was actually produced by a

stage fog, and the result does persist as you've described.

I've never liked those, mind - inhaling the results is allegedly
harmless, but I've always had my doubts.
Apparently a lot of opera singers would agree with you - machine-produced
fog effects are apparently very popular with the stage directors, but the
singers complain that the fog makes their throats sore. :(
