Transmitting sound by vibrating materials
Purpose: To improve the sound of the traditional homemade "tin-can" toy phone.

Overview: Sound is formed by an object moving back and forth, or vibrating. These vibrations move molecules in the air by first compressing them and then causing them to spread apart. In order for us to hear something vibrating, the object must be quivering with enough force for our ears to detect it (loudness). It must also be vibrating between about 16 and 20 thousand times per second, which is the frequency response of the human ear.
