Can you use Newton's third law to explain why a blown up but untied balloon will fly around the room when you let it go?

Please see below.

Explanation:

According to Newton's third law of motion "for every action, there is an equal and opposite reaction".

As a blown up but untied balloon is released, the air trapped inside the balloon pushes out of the open end. This causes the balloon to move forward.

The force of the air escaping is the "action"; the movement of the balloon forward is the "reaction".
