This monaural recording was made with a WWII surplus hydrophone immersed in a glass of water in which a dry lump of pottery clay has been dropped. The clay immediately starts absorbing water and gradually exfoliates, emitting air bubbles and clouds of clay until it has turned into a layer of mud in the bottom of the glass. The process takes quite a while, and generates all manner of interesting sounds in the process, hence I've uploaded MP3.

This was recorded in 1992 with a Sony Walkman Pro cassette recorder. The underwater microphone looks like a hockey puck and is of unknown origin, thought part of a submarine hydrophone array. The microphone preamp is one of my own design and construction.
