what are the fact behind in it.
Small sound can still make a big noise when you use a good sound conductor. Experiment with balloon and compressed air. Find how it works with your own ear.
What you'll need:
1. Balloon
Instructions:
*Blow up your balloon.
*Hold the balloon and get close to your ear while you tap lightly on the other side
What's happening:
Hear the noise loudly when slapping lightly on the balloon. By blowing the balloon you forced the air molecules inside the balloon closer together, they become a strong conductor of sound waves than the ordinary air around you.
Nice
