Been a while since I had anything to do with a rock&roll stage, but I'd
speculate the dry-ice-in-water fog lingers for the same reason ocean fog
does: It's a water-saturated air mass that's been cooled below its dew
point, so small-enough-to-stay-suspended water droplets precipitate.
The droplets can't evaporate again until the air mass they're in has
warmed up. (Even then, the evaporation must take some finite time.)
