[TheForge] boing boing pond.

Chirp is a much better term, consider it adopted thank you. As interesting
and weird as water is, ice is even weirder. I wouldn't be surprised if the
chirping is the sound of an impact phase change resonating through a damping
media.  Maybe nuclei are excited by romantic radio waves. <grin> I'm sure
something can be learned from the effect but is there practical uses? Beyond
more knowledge that is.

I know about how easily X-rays can be generated, unwrapping Saran wrap will
do it too. I think the Scotch tape method was discovered first, I don't
know. The Saran wrap method was used in an episode of the TV show "Bones" to
x-ray a piece of evidence during a power outage. That's only to show how
common the knowledge is if Hollywood is using it accurately. Then again
Kathy Reichs the writer director, creator of Bone is herself a forensic
pathologist and insists on a reasonable validity to the science in the show.

The world is so full of cool stuff a boy has to wonder what the rest of the
multiverse has to marvel about.

I saw that.  The sound is indeed cool.  To my ear, it sounds like a "chirp",
which is a scientific term, believe it or not, for a waveform that (you
guessed it!) sounds like a chirp!
http://en.wikipedia.org/wiki/Chirp
I learned about this waveform from a discussion (?) of Fourier-transform
NMR, in which the radio signal exciting the nuclei may be delivered as a
chirp in order to scan the wavelength spectrum.
Now, this makes me wonder WHY a chirp is produced by skipping rocks, and
whether anything can be learned from it.  I( get on these rants every now
and then since somebody discovered you could produce X-rays using scotch
tape!  http://en.wikipedia.org/wiki/Scotch_Tape#X-rays)
