Balloon rocket

Last week our class did a science experiment in room 15. We got given a piece of paper that had some stuff written down on it, we had to write down what we thought was going to happen before we did some science. I hope you enjoy! :)
Balloon Rocket!


Equipment:
  • 3 balloons (just incase if one or two of them pop)
  • 1 long piece of kite string (about 10-15 feet long)
  • Tape
  • 1 plastic straw


Method:

  1. Tie one end of the string to a chair, door knob, or the other support.
  2. Put the other end of the string through the straw.
  3. Pull the string tight and tie it to another support in the room.
  4. Blow up the balloon (don’t tie it.) Pinch the end of the balloon and tape the balloon to the straw shown below. Now you're ready to launch!
  5. Just let go of the end and watch it zoom off.
    Prediction
    Zeb: The balloon will fly across the line.
    Tyrone:The balloon will go across the line like a rocket and run out of oxygen or air in it and it will stop.
    Observation
    Zeb: The balloon went zooming across the line.
    Tyrone: The balloon flew across the string and got from one chair to the other.
    Explanation
    Zeb: The air was pushing the balloon across the line.
    Tyrone: The air or oxygen comes out of the balloon causing it to move the opposite direction of the end of the balloon.
