A traveling exhibition about the sounds and songs of life

Make a Vocal Cord Model

Courtesy of the Make It team (at the Science Museum of Minnesota's Youth Science Center).

Tools: Rubber Band, Plastic Cup, A Straw. Instructions: Wrap the rubber band around the cup so it is stretched over the top and the bottom. Hold the cup upsidedown in one hand. With the other hand, point the straw -- held flat against the bottom of the cup -- at the band on the cup and blow! You will see the band vibrate and, therefore, make noise.
