The Sound of Glass by Bohyun Yoon uses Water as its Medium

The Sound of Glass by Bohyun Yoon is an interesting device which creates sound through the relay of water. The device is made from a single piece of molded glass transformed into a hollow shape, giving it the ability to create different sounds.

There is also a spout on the Sound of Glass helmet with which its wearers can pour water into other helmets. The idea is to create unique sounds using the water and spouts as a form of performance art.
