Water puppetry (Vietnamese: Múa rối nước, lit. "puppets that dance on water") is a tradition that dates back as far as the 11th century CE when it originated in the villages of the Red River Delta area of northern Vietnam. Today's Vietnamese water puppetry is a unique variation on the ancient Asian puppet tradition. The puppets are made out of wood and then lacquered. The shows are performed in a waist-deep pool. A large rod supports the puppet under the water and is used by the puppeteers, who are normally hidden behind a screen, to control them. Thus the puppets appear to be moving over the water. When the rice fields would flood, the villagers would entertain each other using this form of puppet play.
