20 frames from Albert Freiherr von Schrenck-Notzing's cinematographic film taken on 25th of June 1913 of Stanisława P emitting oral ectoplasm. The bright flash from the photographic process caused the sensitive substance to retreat back into Stanisława, which is what you are viewing here. The complete film is archived at the University of Freiburg at the Institute of Parapsychology.
