What is water rocket?

A water rocket is a type of rocket that uses water as its reaction mass. It works on the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

Water rockets are typically made from plastic bottles and are filled with water and pressurized air. The air pressure builds up inside the bottle and, when released, propels the rocket into the air.

Water rockets are popular among hobbyists and science enthusiasts as they are simple and inexpensive to build, yet can achieve impressive heights and distances. They are often used in educational settings to demonstrate principles of physics and aerodynamics.

Water rockets can be modified and customized in various ways to improve performance, such as changing the amount of water or air pressure, adding fins or a nose cone, or using different nozzle designs.

Overall, water rockets are a fun and educational way to explore the science of rocketry and propulsion.
