The normal liquid the photo studio was no longer usable within a short time. The mist hung in the room and it was a single soup. Since then helped only open the door and blow with the wind machine the smoke out. With fluid B which is much better, the fog is so long since as I need him for the recordings and will disappear within a short time. Only if I smoke machine too strong operated remains this fog a long time hanging in the studio, but that is not to compare the length of time ago with the normal fluid.
