Fun Balloon Facts
If the sound of a balloon popping startles you, you’re not alone. A bursting balloon actually creates a small sonic boom! Once a hole is made in an inflated balloon, the quick release of the balloon’s energy, or air, causes the hole to grow at almost the speed of sound in rubber. Since this speed is much higher than the speed of sound in air, the hole in the balloon actually breaks the sound barrier, creating a sonic boom.
