Balloon rockets

The campers made balloon rockets today – and you can too!

You will need:

  • 1 balloon (round ones will work, but the longer ones work best)
  • 1 long piece of kite string (about 10-15 feet long)
  • 1 plastic straw
  • tape

Instructions:

  1. Tie one end of the string to a chair, door knob, or 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 (but don’t tie it.) Pinch the end of the balloon and tape the balloon to the straw as shown above. You’re ready for launch.
  5. Let go and watch the rocket fly!
