        ZOOM | Experimenting with a Glass Xylophone

        The cast investigates how the pitch of sound changes when they strike a variety of glasses filled with different amounts and types of liquids in this video segment adapted from ZOOM. When you hit an empty glass with a spoon, both the glass and the air inside it vibrate. You hear these vibrations as sound through the air.
