Wind Chimes, Jewels and Clay Oh my!

 

Wind chimes are musical garden decorations that make gentle sounds when the wind blows them. They use science, history, and different materials to create sweet outdoor music. [1, 2]

Ancient Magic and History

Scaring bad luck: People in ancient Rome and China hung up early wind chimes more than 2,000 years ago because they thought the ringing breeze would scare away bad spirits. [1, 2]
Protecting crops: In places like Indonesia, farmers hung up loud shell and bamboo chimes to make noise and scare hungry birds away from their food plants. [1]

The Science of Sound

Vibrations make notes: When the wind pushes pieces of a chime to bump together, they wiggle back and forth. This quick wiggling is called vibration, and it makes sound waves travel through the air to your ears.
Size changes pitch: Short metal tubes make high, squeaky notes, while long tubes make deep, booming notes. [1, 2, 3]

Different Materials

Everything makes music: You can make chimes out of metal spoons, old keys, sea shells, glass beads, or dry bamboo.
Unique sounds: Hard metal sounds bright and clear, while wood and bamboo make a soft, cozy clacking sound.
