Chemical make-up of movie theater air shifts w/ movie moments

posted by Jason Kottke   Aug 08, 2016

A study undertaken by a group of German scientists suggests that the chemical makeup of the collective breath of movie audiences change in reaction to what’s happening on the screen.

Human beings continuously emit chemicals into the air by breath and through the skin. In order to determine whether these emissions vary predictably in response to audiovisual stimuli, we have continuously monitored carbon dioxide and over one hundred volatile organic compounds in a cinema. It was found that many airborne chemicals in cinema air varied distinctively and reproducibly with time for a particular film, even in different screenings to different audiences. Application of scene labels and advanced data mining methods revealed that specific film events, namely “suspense” or “comedy” caused audiences to change their emission of specific chemicals.
