1. 1 balloon (round ones will work, but the longer “airship” balloons work best)
2. 1 long piece of kite string (about 10-15 feet long)
3. 1 plastic straw
4. Tape
Directions from https://sciencebob.com/make-a-balloon-rocket/:
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.) Tape one end of the balloon to the straw as shown above.
5. Let go and watch the rocket fly!
