Bottle Rocket Launcher

Turn almost any plastic soda bottle into a rocket, using water as the propellant, with this solid, durable metal launcher equipped with a simple triggering mechanism.

Operation requires an ordinary bicycle pump (not included).

Users can vary the fin size and placement, vary the water level and air pressure, measure rocket altitude with the included paper astrolabe, and even loft a full-size soccer ball with this investigation of the conservation of action and reaction momenta.

The launcher must be stuck into the ground, and aligned to the intended direction of launch.

For outdoor use only.
