Sounds of Science

Talking Strips

Talking strips contain recorded messages on plastic, just like a phonographic record. To play the message your thumb becomes the record needle. Talking strips about sound waves. 

Big Lightning Thunder Tube

Grasp the Thunder Tube in the middle with one hand and let the spring hang down. Make the spring dance by shaking your wrist and the air comes to life with sound! The tube works like a drum being played by the spring. Sound waves are created within the tube and the waves resonate back and forth against the sides of the tube, amplifying the sound.

Sound Hose

Twirl the tube above your head and the air molecules drifting inside are in for a ride! They begin to bump against each other and vibrate, creating sound waves that you can hear. The faster you move the Sound Hose, the higher the pitch. Experiment with different speeds to pick up the whistle.
