Unfiltered local tap water, piezo microphones, audio mixer, active speakers, cables, coated veneer plywood
An ice cube made of unfiltered tap water. The volume of 85 litres is determined by the length of the exhibition being four days. By the end of it, the ice will have melted completely; or it will set against the prediction and still remain after the end of the exhibition. The puddle is growing.
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 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 surfacing during the melting.
The less ice is left and the microphones fall off, the more the audio setup is likely to generate feedback.
