How does the pitch change when the balloon is tighter?
Balloons can make some fun noises when you pinch and stretch the opening as you let the air out! The reason a balloon makes a higher pitch when you pull tighter comes from the amount of movement allowed. Because the air pushes through the opening of the balloon against the tightened rubber, this rubber vibrates as it gets pushed apart and pushes back together against the air. The tighter this opening, the less leeway the rubber has to move, and the faster it will vibrate, causing a higher pitch.
