Researchers investigated the air
in movie theaters to learn how to predict the level of excitement in the
show being watched. The revealing chemical patterns exhaled in this “crowd
breath” are most clearly noted during suspenseful scenes in movies, and are
consistent across multiple viewing audiences. The scientists say the rise in
both CO2 and isoprene are a result of the accelerated breathing induced by a
suspenseful movie scene.
