What's the best design for a water rocket? Answered
There's two parts I'm wondering about: - fin design - recovery system design I'm planning to use angled fins. What angle is best? Does the shape of the fins matter, or can I just make triangles out of cardboard? For the recovery system, which is better: airspeed flap or "nose separates at apogee"? The second one is definitely easier to build, though.
