Echo Tubes UN Plaza
Echo Tubes UN Plaza
Talk, clap, yodel, yell—your sounds bounce back at you.
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? The Echo Tube is a long-time Exploratorium favorite, but here the tubes have an added feature: people can use them from either end, setting up opportunities for two-sided play and collaboration.
