Echo Tube
Make a sound into the echo tube and listen for it to reflect back from the far end. You’ll hear a half-second delay, and strange distortions created by the journey.

Echo Tubes
Experiment with echoes with these three long tubes. Why does a clap come back as a ping? What does it take to make a good echo?

Lariat Chain
This artwork by Norman Tuck demonstrates that a very simple system—a metal chain hanging from a motor-driven bicycle wheel—can generate complex behaviors.

Wave Organ
Sound at this wave-activated acoustic sculpture is created by the impact of waves against the pipe ends and the subsequent movement of the water in and out of the pipes. The sound heard at the site is subtle, requiring visitors to become sensitized to its music, and at the same time to the music of the environment.
