Paintball is a superb and exhilarating game, whose popularity grows with each passing day. Psychologists believe that paintball is a way to get rid of stress and feelings of aggression. Participants in the sport of paintball are armed with markers (a compressed air rifle) that fire paint-filled balls in an attempt to shoot opponents. If the player is hit by a ball that leaves a colored spot at least the size of a lats, he is considered killed and is required to leave the field until the next game. A typical game will last 10-15 minutes.
