Water rockets use water and air modern rockets use thrust and oxygen.
Yes, the NASA website even has tutorials for how to build water rockets with body tubes.
No they cannot. Why do you think that they're called 'dirt rockets'
Less water more air
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!
air and water
Newton's third law
No.
Model rockets can use anything from 1/4A to G engines.Amateur rockets can use up to N engines.Professional rockets have no limit.Each successive engine letter has twice the power of the previous. Assuming Professional rockets start with O engines, the smallest Professional rocket engine has 256 times the power of the largest Model rocket engine. Most will of course be much larger.
If you have a parachute, then it allows your water rocket to land safely.
toys r us thanks
Space shuttles, space rockets and also the atmosphere
