When you bend it, indium gives out a "cry" much like the better-known "tin cry". Neither of them is really much like a cry, as you can hear if you play the sound for this sample.
This sound file is a bit larger than most, because it's a super-high fidelity recording made in the "dead end" studio at WGBH Boston, using the finest high sensitivity microphones available, and I didn't want to lose anything by compressing it. My host family when I attended the Ig Nobel Prize ceremony, Jane and Miles, are both sound engineers at WGBH, and they kindly set up a recording session to capture this important element sound.
When Oliver Sacks came to visit me he liked these bars so much that I gave him one to take home, so there are actually only two left in the table.
