The HydroLaunch Water Rocket System is not a basic water rocket – it is a complete solution for implementing science and engineering practices (SEPs) in the K-12 classroom. Whether it is the introduction of mechanical complexities that enable students to engage in hands-on engineering of a water rocket, or the planned deployment of a parachute with precision, students become NASA engineers in their launch mission. The HydroLaunch Water Rocket System also requires students to consider and compare the effects of a multitude of variables upon their rockets: rocket mass, air pressure, water volume, nozzle size, fin shape and more. 

Unlike other Water Rockets available on the market, the HydroLaunch® is a complete system that provides all the features expected in a model rocket – from an aerodynamic nose cone to precision cut fins, all you need are a couple of soda bottles and a standard bike pump for your next rocketry adventure.

Highlights:

• HydroLaunch Water Rocket Launcher - A launcher that allows you to pressurize and launch using the same pneumatic line, and adjust launch angles. It comes with a launch rod to enhance launch stability.
• LaunchTrak Nose Cone - A polyurethane nose cone weighing just 85 grams to make your water rocket aerodynamic. Specially designed to house the LaunchTrak altimeter (sold separately), this nose cone adds advanced capabilities to your water rocket.
• Nozzle - Threads mated with standard soda bottles, and slots for low profile detachable fins, these rocket nozzles enable you to make a variety of rockets with different size soda bottles.
• Nozzle Inserts - 8mm, 10mm and 12mm standard inserts come in your HydroLaunch water rocket kit, enabling you to experiment with a variety of thrust profiles.
• Fins - Low-profile detachable fin holders compatible with the nozzle enable you to use either standard fins (included in the HydroLaunch kit) or build your own with our simple guide.
• Elev8Eject Parachute Eject Mechanism - The parachute eject mechanism uses a tilt switch to deploy parachutes at apogee, with 0° to 45° launch angles from the vertical.
  

STEM Curriculum:
The HydroLaunch Water Rocket System is an NGSS aligned, STEM Curriculum Education Kit that introduces students to rocket science fundamentals across four levels of education.

• Level I (Grades K-2)
• Level II (Grades 3-5)
• Level III (Grades 6-8)
• Level IV (Requires BETA Test Chamber) (Grades 9-12)

Advanced Kit Includes:

• 1x HydroLaunch Water Rocket Launcher
• 1x HydroLaunch Elev8Eject Parachute Eject Mechanism
