Abstract
A projectile substance is pneumatically propelled. The projectile substance is inserted into a longitudinal bore (23) of a barrel (22) and a rupture disk (54) is attached to a first end of the barrel (22). Next, the first end of the barrel is coupled to a first end of a pneumatic reservoir (26) having a chamber (27) therein. The rupture disk (54), as attached, acts to form a seal between the longitudinal bore (23) and the chamber (27). Then, a gas is introduced into the chamber (27) until a sufficient pressure is attained within the chamber (27) to rupture the disk (54). When the disk (54) ruptures, the gas in the chamber (27) rushes into the longitudinal (23) bore with sufficient force to propel the projectile substance out of the barrel (22).
