Question

If a balloon is filled with air and its mouth untied, then air is released from its mouth in the
downward direction. Write other observations made by you. Justify your answer.​

Answer 1

Explanation:

The pressure wants to equalize, so when the mouth of the balloon is opened, air rushes out the hole. Since the hole has a narrow aperture and the pressure inside is high, this produces sufficient thrust to move the very light balloon in the opposite direction of the escaping air
