Then suspend various aluminum objects in it while in operation, there are many strange sounds produced. I recorded two sessions so far with a DA200 recorder. I will release a few of the messages so far.

The listening technique is to listen at very low volume level and then turn it up slightly as you hear the message. These are quite noisy.

I hear a male voice speaking in a monotone

"I'm testing from Jupiter"

I slowed the speed by 10% using Audacity and hear:

"i once came from Jupiter"

 A quick look at wikipedia informs that Jupiter is also a town in Palm Beach County, Florida.

Very interesting experiment and soundclips!
