Paintball
Paintball is a sport in which players try to eliminate opponents by shooting each other with balls of coloured dye. The players can compete either in teams or individually. The balls of dye (called "paintballs") are shot through a device called a paintball marker (or paintball gun). When the paintballs hit, they release the dye. When they hit a player, the dye marks that player as eliminated. The game is often played as an organised competitive sport, involving leagues, tournaments, and professional teams.
