Powderpuff football games are flag football or touch football games involving girls from junior and senior grades or cross-town school rivals in the United States and Canada. The proceeds from the game's ticket and concession sales are usually donated to charity, the senior class, or a dance. These games can be played as either an exhibition or a contest. Powderpuff is the name given to the ball used in the game. It is a soft, spheroidal object, usually made of rubber, although some games use balls made of feathers or corn. In most cases, the goal is for there to be no injury to the players. If a player is injured during play, they may be removed from the field on a stretcher. If a player appears unable to continue, then they may be replaced by a substitute. The first powderpuff game was played in Chicago in 1894. That same year, the original rules were written up by Mrs. Carrie Chapman Catt. The game has evolved over time with changes being made by its administration team (known as the "tag team"). Today, there are more than 600 active teams in the US, Canada, and England. Games are played throughout the year, but especially during the winter months. Powderpuff is a unique experience that brings together students from different schools in a fun environment. It can be played as a competitive event or as a display of skill.
