Percussion and string instruments have already been explored. This exhibit examines another way to make sound, this time using air, i.e. a wind instrument. Children can move a set of pan pipes along a slider and a ventilator blows air over the top of the pipes when the green button is held.
A fast stream of air moving over the top of a pipe causes the air in the pipe itself to vibrate, creating a sound. The length of the pipe affects the pitch of the sound, creating a higher or lower note.
This small exhibit encourages visitors to lean close and listen carefully.
