Water rockets need fins because the rocket needs to stay in balance....without fins on a water rocket, the water rocket would be going out of control because it is not in balance!
No, rockets do not need fins in space because fins are used for stability and control in Earth's atmosphere, not in the vacuum of space. In space, rockets rely on thrusters for maneuvering and direction control.
Rockets need fins to help stabilize and control their flight trajectory. Fins help provide directional stability by creating aerodynamic forces that keep the rocket pointing in the right direction. This is important for ensuring that the rocket can accurately reach its intended target.
birds are alive and rockets dont need air to fly birds have wings and rockets have tail fins
you put fins on the rockets
Fins are used to stabilize a rocket, so that it does not veer off course or tumble. However, most larger rockets do not use fins because of the atmospheric drag they create.
Fins.

because without the wings the plane would be unstable and crash. by:jake tompson
Three fins are needed on most model rockets. More is ok if aligned properly, but less will cause instability in flight.
