Balloon Rocket Experiment!

Balloon Rocket Experiment! Supplies for this experiment are string, straw and a balloon. Tie the strings between two chairs. Thread a piece of a straw on the string. Blow up a balloon and tape it to the straw. Once all set up release the balloon. AGES 4+
Jalen and I had some great conversation during this experiment. What happens if you put more/less air in the balloon? How do we get the balloon to stick to the straw? Does it make a difference if we use one piece of tape or two? What is pushing the straw to move?
