A launcher powered by a hand bicycle pump or small compressor fills a plastic pop bottle rocket with compressed air. When the bottle is released from the launcher, air escapes the bottle. As the bottle pushes out the air, the air pushes the bottle upwards (Newton's Third Law of Motion).

What do you put in a bottle rocket?

Typically, a water rocket uses a plastic bottle in which the pressurized air, and water, goes in. When the air pressure becomes high enough, the plastic bottle releases and flies high up into the air. The higher the air pressure, the faster the water shoots out, and the greater the “push” force on the rocket.
