How a 2 liter bottle rocket works?

A 2-liter bottle rocket operates on the principles of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The rocket is filled partially with water and pressurized air is added through a pump. When the pressure builds up sufficiently and the launch mechanism is triggered (often by releasing a cork or stopper), the pressurized air forces the water out of the bottle, propelling the rocket upward. The rapid expulsion of water creates thrust, allowing the rocket to ascend into the air.
