take 2 l. bottle
cut the bottom of a bottle off
put the 2 bottles together
take a piece of balsa wood and make the wings
fill the bottom part of the water rocket with paper
put the wings on the bottle rocket
cut a circular cup in half
put a tennis ball on the cup
a rocket powered by water
it will become an air powered rocket
the rocket is pushing water downwards which means that the water pushes the rocket upwards very hard that it can overcome gravity and fly.
If you have leaks in a water bottle rocket, the pressure will quickly escape along with the water and the rocket won't be able to reach as high an altitude as a rocket without leaks.
The duration a water rocket stays in the air can vary based on the pressure level in the rocket, the design of the rocket, and external factors such as wind speed. On average, a water rocket can stay in the air for around 5 to 20 seconds.
There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
The manipulated variable in an experiment with a water rocket could be the amount of water or air pressure used to launch the rocket. This variable is intentionally changed by the experimenter to observe its effect on the rocket's performance.
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!
A water rocket should probably have three to four fins.
Water serves as the reaction mass in a water bottle rocket. When the water is pressurized and released, it creates the thrust that propels the rocket into the air. Additionally, the water helps to stabilize the rocket by shifting its center of mass downward as it is expelled.
Jean Le Bot's first water rocket was launched in 1888. It was a pioneering experiment where he used water propulsion to launch a rocket. The rocket successfully reached a height of 12 meters before coming back down. This event laid the foundation for further developments in water rocket technology.
