An air blown projectile cannon, preferably softballs, comprises an electric fan that blows the projectile from the cannon. Preferably, the cannon is a self-contained domed or spherical unit that may project balls almost continuously without multiple button pushes or the like. There may be a magazine for holding multiple balls. The housing may be mounted on a frame so that the cannon may be aimed horizontally and vertically, the frame also having an integral seat or stool for the cannon user. For ease of use, the fan should be mounted at the centre of gravity of the domed casing. The casing is preferably acrylic or plastics. |
