This is the basic Hydroflite Launcher. It comes with everything you need to launch plastic soda pop bottles up to 250 feet in the air. All you need to provide is the plastic bottle and a tire pump or air compressor.  When you fill the bottle about 1/3 full of water and pressurize it, the rocket will shoot off the launcher and reach a velocity of up to 200 miles per hour! As the water is exhausted, the remaining compressed air comes out with a bang. You can also launch your rockets with just air. (This makes Winter launches more enjoyable because you won't get splashed.) Take a look at the center picture below. The left launch is using water and air. The water comes out in a straight stream. The splashing nearly obscures the launcher. The right launch is with just air alone. The rapid pressure drop of the air causes condensation and you can see the fog. The plume shows an expansion after it exits the rocket throat.
