Balloon Rocket Experiment

Balloon Rocket

Hypothesis (What I think will happen)

I think that it won’t go really far but it will still work.

Materials

• String 10m
• Straw
• Balloon
• 2 chairs
• Sello tape

Method (What we did)

1. Tie or tape string to the chairs
2. Place the straw on the string with it going through
3. Blow up the balloon do not close off the end
4. Pinch together the end then tape the big body part to the straw with the open facing the way that there is no string.
5. What and see what happens.

Observation (What happened)

The balloon went flying because the air was all rushing out of one hole and that caused it to go flying.

Conclusion (Why I think it happened)

Because the air was all rushing out and making the balloon move.
