ABSTRACT:
A bottle rocket launcher comprises a long hollow tube barrel having an tube-axial sealing valve that has a rotary cylindrical or spherical valve member where the valve is attached at the breech end of the launcher barrel. The rocket launcher can be angled up to a near vertical position with support legs. In use, a bottle rocket can be partially inserted into the valve passageway that is held open. The flammable rocket fuse is lit and the bottle rocket is dynamically inserted by hand contact with the rocket stick into the barrel inside chamber body to a position that is beyond the valve member. The valve is rotated into a valve-closed position while the rocket fuse is burning. When the bottle rocket powder is ignited by the burning fuse, the burning exhaust gases thrusts the bottle rocket along the inside of the barrel tube and propels it into the sky in the direction that the launcher barrel is pointed. The rocket exhaust gasses are all restricted to the valve sealed interior confirms of the launch barrel, which protects the operator from the gases or from a premature explosion of the rocket. The launch tube may be independently supported on the surface of the ground or the launch tube may be used as a hand-held device.
