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.

    This is so wonderfully grody and unsettling, and it's far and away one of my most favorite sounds to have accidentally discovered—thank you!

    This really cracked me up in a big grin. Such a splendid creativity! I'm loving all sorts of funky sounds, and this definitely falls into that category. Great recording! I doubt I can find any use for it, but I'll download it in a moment anyways because of that this sound is so cool!

    What a great sound! Thank you so much for sharing this! Wrapping a mic in a condom and taping the heck out of the end works pretty well in a pinch too. :-)
