Science of Sharing

From The San Francisco Examiner:

“Science of Sharing,” a permanent new area of 15 displays and games at the Exploratorium, encourages visitors to study their own behavior. The exhibit is devoted to experiences that shed light on the interplay between science, society and culture. The area was developed by a social psychologist and includes sections like the Trust Fountain, a two-person drinking fountain in which a stream of water for each participant is controlled by the other.
