Balloon Rocket Science Activity


  • Balloon
  • Paper clips
  • Thin wire or string
  • Tape
  • Drinking straws
  1. Hang the wire or string across the room.
  2. Make a rocket that will propel itself along the wire.
  3. Use the balloon to provide the rocket's power and the straw, paper clips and tape to guide it along the wire.
  4. Use your imagination and your knowledge of air power to make the balloon travel across the room. Remember, the air that is forced out of the balloon pushes the balloon along in the opposite direction.
Can you make a rocket system that will get across the room and then come back again?! Draw a diagram of your design.

Note: This science activity is based on Newton's Third Law of Motionevery action has an equal and opposite reaction.
