The ultimate addition to the Ultimate Water Rocket Launch Pad! This is the same launch system as used at the National Science Olympiad Competition. It provides a launch that is exactly the same every time. The rocket is pressurized and released by pushing buttons. Rocket pressurization occurs in under 5 seconds. You push the button and the rocket is launched. This system requires a large compressor (example: 1.5 horsepower motor and a 5 gallon tank or better.) or other constant pressure supply (i.e. SCUBA tank). It also requires high pressure line from the compressor to the launch system. Many states use this system at their respective regional and state competitions. (Arizona, Illinois, Nebraska, Pennsylvania, California, Kansas, North Carolina and others pending.)

NOTE: This upgrade kit is not a complete launcher - it is only to convert your existing Ultimate Water Rocket Launch Pad to a pneumatic system. You will need to ship your pad to us. We'll perform the upgrade and ship it back to you.

This is needed if your compressor is: 1: located at a distance, or 2: You don't have a gauge or a reliable gauge on your bicycle pump or small compressor.

This is needed if you have a large compressor. The regulator is used to adjust the pressure at the launch pad to the desired pressure. This is also a safety feature....it keeps the students from over-pressurizing their rockets.

This item allows you to replace the 2 liter nipple on your Ultimate Water Rocket Launch Pad with one that will launch 3 liter bottles. The two nipples are interchangeable. This nipple works only with the non-pneumatic launch pad.
