Resources required:
1 balloon (round ones will work, but the longer ‘airship’ balloons work best), 1 long piece of nylon thread, 1 plastic straw and tape.

Description of investigation:
Tie one end of the string to a chair, door knob, or other support.
Put the other end of the string through the straw.
Pull the string tight and tie it to another support in the room.
Blow up the balloon (but don’t tie it). Pinch the end of the balloon and tape the balloon to the straw as shown here.
You’re ready for launch!!!!! Let go and watch the rocket fly!

Investigation Questions:
Does the shape of the balloon affect how far (or fast) the rocket travels?
Does the length of the straw affect how far (or fast) the rocket travels?
Does the length of the string affect how far (or fast) the rocket travels?
Does the type of string affect how far (or fast) the rocket travels? (try fishing line, nylon string, cotton string, etc.)
Does the angle of the string affect how far (or fast) the rocket travels?
