Balloon Rockets
Launch your own balloon rockets and watch them zoom through the air! Kids love the thrill of seeing their creations take flight and it’s a simple way to introduce concepts of physics and air pressure.
Educational Value
Teaches principles of propulsion, air pressure, and basic physics.
Materials Needed
Step-by-Step Instructions
- 1
Cut a piece of string about 10 feet long and tie one end to a chair or a fixed point.
- 2
Thread the string through one of the straws and tie the other end of the string to another chair or fixed point, making sure it's tight.
- 3
Inflate one of the balloons without tying it off and pinch the end to keep the air inside.
- 4
Tape the pinched end of the balloon to the straw on the string, ensuring the balloon is pointed away from the starting point.
- 5
Once secured, release the balloon and watch as it propels itself along the string.
- 6
Experiment with different balloon sizes and shapes to see how they affect the rocket's speed.
- 7
Try using two straws on the string to create a dual-rocket launch system.
- 8
Discuss with your child the science behind how air pressure propels the balloon forward.
