Spectacular Sonic Blaster

We found out that sound waves cause vibrations in our eardrums.

A big enough sound wave can even make some objects move.

We tested this out by using a tube with a small hole in one and plastic covering the other. We tapped the plastic end and saw that it made the Pom Pom move!

We didn’t think it would work with a bigger object as it would be too heavy.
