Unfiltered local tap water, piezo microphones, audio mixer, active speakers, cables, coated veneer plywood

An ice cube made of 85 litres of unfiltered local tap water. By the end of the four day lasting graduation exhibition, the ice will most likely have melted into the room completely.

During the melting process the ice cube is monitored by four pairs of piezo microphones attached to it. The sound picked up by each microphone pair is given back into the reverberent room respectively by one of the four speakers.

In the freezing process the impurities inside the tap water concentrate as a yellowish core inside the cube, covering the cube in a slimy layer when when getting to the surface.

The less ice is left and the more microphones fall off, the more the audio setup will generate feedback.
