Water rockets, also called Bottle rockets, are like their model rocket cousins, except that these are powered by a combination of water and air pressure instead of a chemical propellant. The pressure vessel, the engine of the rocket, is usually a used plastic soft drink bottle.
How they work
The bottle is partially filled with water (typically a third full), and then inverted so the nozzle points towards the ground. The bottle is then pressurized with air and then released.
Water and air are used in combination, with the air providing a means to store potential energy, as it is easily compressed, and the water providing momentum when ejected from the rockets nozzle (Newton's third law).

Researching Water Rockets, I found out that Nasa is in fact sponsoring a Water Rocket project itself. Interesting! http://bit.ly/4oNlLd

ohh wait. i forgot. ALL Gazans dont deserve access to water & medicine beacause Hamas sends Qassem rockets. Makes perfect sense. Not.

@brampitoyo sure, I'll go to OMSI. Why not? I can play with the water bottle rockets!
