Get Your Science On: Voice Vibrations

In this episode, Mayon shows us an awesome way to see sound using a microphone, speaker, and a piece of rubber!

What’s Happening?

The speaker causes the rubber to vibrate. Depending on the sound you make, different parts of the rubber will vibrate. The places that vibrate the most are called antinodes and the places that don’t vibrate at all are called nodes. The sand gets knocked off of the antinodes and collects at the nodes, so you can easily see the patterns where the fabric is vibrating!
