Water rockets

Bottle rockets or water rockets, what are they?
Water rockets are a source of entertainment and education. They are made with an empty two-liter plastic soda bottle by adding water and pressurizing it with air for launching.
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 to help students understand the principles of aeronautics.
Two-Liter Pop Bottle Rockets may well be the GREATEST PHYSICAL SCIENCE TEACHING TOOL EVER CREATED!!!
Middles grades students can manipulate and control variables, see their hypotheses verified and graph their findings.
High school 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 impuls and momentum, projectile motion, freefall calculations, internal and external ballistics, and the practice of true engineering.
How could something that sounds so simple be so complex? Open your mind to the science and mathematics behind this educational "toys".
Launching soon!!!
