Why Water Bottle Rocketry:
Model rocketry is an exciting and educational activity that can be enjoyed by all ages. Water bottle rockets are built using soda bottles of many different sizes and are pressurized with a bicycle pump and then launched with the aid of a specialized launcher. Flights of over 400 feet are possible. Water bottle rockets can focus students on many different concepts and have many advantages over solid fuel model rockets.

Advantages Over Solid Fuel Rockets:
  • Cheaper rockets. Water bottle rockets can be built for a few pennies.

  • Much faster. Water bottle rockets can be built in minutes and flown immediately.

  • Safer. Water bottle rockets are propelled by air pressure, not hot gasses. You control the launch pressure.

  • Construction flexibility. Water bottle rockets can be very simple to construct using found materials or very finely crafted using aerodynamically shaped fins and other more sophisticated materials.

 What Rocketry Can Teach:
  • Newton's laws of motion

  • Flight guidance

  • mass

  • aerodynamic stability

  • drag

  • measuring altitude

  • velocity

  • center of gravity

  • center of pressure

  • propulsion

  • thrust

  • force

  • pressure

  • PSI

  • square root

  • surface area

  • volume
