Abstract
A projectile suitable for launching by a gun or similar weapon, having a hollow housing within which there is carried a pressurized container having the material to be delivered therein. A piercing pin within the housing is spaced from the bottom of the container. When the projectile is launched by the firing of the weapon, the inertia of the container causes the piercing pin to penetrate the bottom of the container. The pin and container remain together until the projectile's forward motion is sharply reduced as by striking an object or the ground. The piercing pin is thereby dislodged, releasing the delivered material under pressure into the atmosphere. Stabilizing fins and weights are provided to control the flight of the projectile.
