Information about water rockets

Bottle rockets or water rockets, what are they?


When someone mentions bottle rockets, do you envision placing a firecracker attached to a stick into a glass bottle and launching it?


Water rockets have been a source of entertainment and education for many years. They are usually made with an empty two-liter plastic soda bottle by adding water and pressurizing it with air for launching.


Soft drink (soda) companies began using plastic bottles in 1970. The Polyethylene Terephthalate (PET) material used in most plastic soda bottles today was introduced in 1973.


Water rockets are used in schools to help students understand the principles of aeronautics. The Science Olympiads provide challenges of bottle rocket design and flight, including altitudes and distances reached. Many interesting designs and additional information on bottle rockets can be found with a simple Web search.


"Two-Liter Pop Bottle Rockets may well be the GREATEST PHYSICAL SCIENCE TEACHING TOOL EVER CREATED!!" students can manipulate and control variables, see their hypotheses verified or refuted, and graph their findings. Older students experience the nature of science at its best. They can document their abilities with the following concepts: inertia, gravity, air resistance, Newton's laws of motion, acceleration, relationships between work and energy or impulse and momentum, projectile motion, freefall calculations, internal and external ballistics, and the practice of true engineering.
