Excellent! I can recall screaming when I came into contact with dry ice as a kid ::))

I had never heard of this before. That would be good live. I wonder what it would be like if a person was in the metal container?

life sciences come alive ;)) ... nette Zellkultur im Hintergrund!

Hey RC!!..  i was watching this on youtube when you uploaded it, don't think i left a comment, but sounds so different when not watching the video, kinda scary....  bit like those mysterious sounds that came from the atmosphere over Russia not so long ago

you made a really nice piece with this experiment, using contrast and blending, volume controlling....(some of it is naturally occurring I bet, but some you made too?)

assembled and recorded a noise generator:  metal containers, filled with hot water, generate these sounds when put on dry ice.

Metal objects screeching and screaming when coming into contact with dry ice is more or less common knowledge, but I experimented a bit to make these usually short noises last longer, this is the result.
The occasional cracking noises come from ice crystals that pop up at the bottom of the container.
