Each person needs one plastic soda bottle.

• We will be using water rockets and air pressure. PSI = pressure per square inch

• The pump is used to pressurize the inside of the body tube to provide thrust for the rocket.

• Fins are attached to the bottom of the body tube to provide stability during the flight.

Fins cannot be flimsy

• Expect Rotation, Center of gravity is important. Don’t be top heavy

• Rotation is important because the flight path will be more stable.

• A rifle is an accurate weapon because the bore of the rifle causes the projectile (bullet) to spiral.

• Your rocket should be aerodynamic: The least resistance through the air.– Your rocket should have a nosecone.

• Lift and Drag – Two aerodynamic forces

• This cheesy rocket design would have too much weight and drag to successfully take off.

• We will have a launch pad

• We won’t have a guidance system like this rocket.

• We won’t have a guidance system like this rocket. – Your rocket should be balanced however and put on

the launch pad for a vertical launch.

• Your rocket should have a payload.

• We will also analyze trajectory / path of rocket when we fire + calculate total elevation.

One standard plastic soda bottle is inverted so the opening becomes the nozzle.

Another can be cut on the bottom and placed on top to increase height of rocket.
