A blowgun (also called a blowpipe or blow tube) is a simple ranged weapon consisting of a long narrow tube for shooting light projectiles such as darts. It operates by having the projectile placed inside the pipe and using the force created by forced exhalation ("blow") to pneumatically propel the projectile. The propulsive power is limited by the strength of the user's respiratory muscles and the vital capacity of their lungs. History Many cultures have used such a weapon, but various indigenous peoples of East Asia, Southeast Asia, Western Europe, North America, Central America (the Huehuetenango region of Guatemala), and South America (the Amazon Basin and the Guianas) are best known for its historical usage. Projectiles include seeds, clay pellets, and darts. Some cultures dip the tip of the darts in curare or other arrow poisons in order to paralyze the target. Blowguns were very rarely used by these tribes as anti-personnel weapons, but primarily to hunt small animals such as monkeys and birds. The North American Cherokee were known for making blowguns from river cane to supplement their diet with rabbits and other small creatures. Blowguns are depicted in paintings on pre-Columbian pottery and are mentioned in many Mesoamerican myths. Back then and today, the Maya use a blowgun to hunt birds and small animals with spherical dry seeds and clay pellets. The clay ammunition is made slightly larger than needed (to allow for shrinkage and refinement) and stored in a shoulderbag. The outside of the dry clay pellet is shaved off and burnished right before use. Shorter blowguns and smaller bore darts were used for varmint hunting by pre-adolescent boys in traditional Cherokee villages. They used the blowguns to reduce the population of small rodents such as rats, mice, chipmunks and other mammals that cut or gnaw into food caches, seed and vegetable stores, or that are attracted to the planted vegetables. While this custom gave the boys something to do around the village and kept them out of mischief, it also worked as an early form of pest control. Some food was also obtained by the boys, who hunted squirrels with blowguns well into the 20th century. Today blowguns are used with tranquilizer darts to capture wildlife or to stun caged dangerous animals. Herpetologists use blowguns to capture elusive lizards with stun darts. Blowguns are also used recreationally, with either darts or paintballs. Sport blowgun There are
