Silent ball is the Psi Chi national game in which a ball is thrown from player to player while everyone remains silent. The game was created to stimulate interpersonal relationships, stemming from experiments by Philip G. Zimbardo.
There may be variations and additions to these rules. For example, if players who are sitting down, because they are "out", are able to catch a throw, then they may re-enter the play. If the ball is tossed inaccurately or in an aggressive manner, then the person who threw the ball is "out". Other adaptations include disallowing players from returning the ball to the players from whom they have immediately received it imposing time limits on how long players may hold the ball before being required to pass it and the teacher of the class joining in.
Silent ball also goes by "Silent Desk Ball" or "Mum ball" by some people
The students are usually the players while the teacher is usually a referee though it is semi-common for the teacher to join as a player. In some instances, the teacher is allowed to cheat in the game.
