Frequently Bought Together
Pressurize. Launch. Learn.
Water-Powered Launch
Newton’s Third Law You Can Feel—Students pump air into a water-filled bottle rocket until pressure builds, pull the release cord, and watch water blast downward as the rocket shoots upward. The equal-and-opposite reaction is not a diagram—it is a soaking, roaring, unforgettable experience.
Aquaport II Launcher for Safe, Repeatable Launches
The pull-cord release mechanism keeps students at a safe distance during launch. The launcher holds the rocket securely under pressure and releases cleanly, giving consistent launches students can compare across design iterations.
Thirty Student Rocket Kits
R2K kits give every student materials and guides to design their own nose cone, fin configuration, and payload bay from a standard plastic bottle. Each rocket is unique—each launch tests a different hypothesis.
Deluxe Port Pump II—Hand-Powered Pressurization
The included hand pump lets students control pressure buildup. Pump more for higher launches. Students learn the direct relationship between pressure, water volume, and thrust—by feel, not formula.
What Students Will Do
- Design nose cone and fin shapes for a plastic-bottle rocket
- Attach fins and nose cone using hot glue and tape
- Fill the rocket with a measured volume of water
- Mount the rocket on the Aquaport II launcher
- Pump to target pressure using the Deluxe Port Pump II
- Launch using the pull-cord release
- Measure altitude and flight time
- Adjust water volume, pressure, fin shape, and nose cone design
- Compete in altitude and accuracy challenges

Why Teachers Love Water Rockets Getting Started Packages
The Most Memorable STEM Day of the Year
Water rockets launch with a roar and a spray. Students remember this lesson for years. The visceral experience of pressure, thrust, and flight cements physics concepts that worksheets cannot.
Thirty Students, Thirty Unique Rockets
R2K kits give every student materials to build their own design. Different fins, different nose cones, different hypotheses—every launch is an experiment.
Water-Powered Means Safe and Reusable
No combustible propellants, no single-use motors. Add water, pump, launch, recover, repeat. Students run multiple trials in a single class period.
Launcher and Pump Included—No Extra Equipment
The Aquaport II launcher and Deluxe Port Pump II are in the box. Students supply plastic bottles. That is the only additional item needed.
Pressure You Can Control, Thrust You Can See
Students pump to a target pressure, launch, and see the result. More pressure, more water, higher launch. The cause-and-effect loop is immediate and measurable.
Competition Drives the Science
Who launched highest? Who hit the target? Students optimize water volume, pressure, and fin design when a trophy or class ranking is on the line.
