Question

We can hear sound. Sometimes, we can see and feel it, too. If you strum on a guitar and look closely at the strings, you can see them vibrating. That vibration is the very sound you hear. If you put a piece of paper over a stereo, you can see the sound vibrating the paper. If you put rice on top of a drum and bang on the drum, you’d see the rice move. Want a simple way to feel sound? Put your hand on your throat and hum.
