This project demonstrates Newton's Third Law of Motion by using balloons to propel themselves along a string. Students will observe how the release of air from a balloon creates an equal and opposite reaction.
If I release air from a balloon taped to a straw on a string, then the balloon will move in the opposite direction of the air release.

Attach a straw to a balloon using tape.
Thread a long piece of string through the straw.
Stretch the string tightly and secure at both ends.
Inflate the balloon but do not tie it.
Release the balloon and observe its motion along the string.
Measure the distance traveled by the balloon.
Repeat the experiment with different balloon sizes.
Record and compare your results.
Analyze how balloon size affects distance traveled.
Discuss how this demonstrates Newton's Third Law.
The balloon will travel along the string, moving in the opposite direction of the air being released, illustrating Newton's Third Law.

Make sure to supervise when cutting string and using scissors.
Use a large poster to show your procedure and results.
Include diagrams of the setup with labeled parts.
Demonstrate the balloon rocket setup live if possible.
Newton's Third Law states that for every action, there is an equal and opposite reaction.
Yes, balloon shape can affect how the air is released and the rocket's speed.
It moves in the opposite direction due to the release of air creating a force that pushes it.
