In this science experiment we will explore Newton's third law which states for every reaction there
is an equal and opposite reaction. In the process we will make some really cool sounds and
launch balloon rockets up about 40 feet in the air.

Process for Balloon Rocket Experiment:
1) Attach a balloon rocket to the pump.
2) Pump it up!
3) Point it up into the air.
4) Let it go.
The Science Behind Balloon Rocket Experiment
The sounds you hear are generated by the air molecules escaping the balloon rocket and the
small plastic lips of the balloon vibrating which creates sound waves. When you release the
balloon rocket it takes flight spinning, circling, and weaving through the air. This occurs because of
Newton's Third Law which states for every action there is an equal and opposite reaction. In this
case the action is air molecules escaping the balloon through the open untied mouth where the air
was pumped inside. The reaction is the rocket balloon being pushed in the opposite direction from
where the air molecules are escaping.
