Tin is a fascinating material with all kinds of interesting properties. My personal favorite: the crying of tin. Bend a piece of tin close to your ear and you can hear the crystal lattice beg for mercy against impending metal fatigue. When it stops crying the piece has torn.

Twelve years later, is there still no accepted explanation of how they form?

Check out Tin Pest on youtube (can't do it at the moment). A most curious behaviour for a metal.

Fascinating, anyone here ever experience problems due to this phenomenon?
