What's the Hardiest Hardware You've Seen?

mrsev asks: "I work in a lab and so have lots of strange equipment around me. Recently I found an old 256Mb USB Flash Disk, that I had been looking for 6 months. This would not be amazing but for the fact that it was frozen in a block of ice in one of our -80C freezers (-112F). It must have fallen from my top pocket when I was reaching in. After chiping it out and a quick thaw and dry ... it worked!! All my data was intact and there were no problems. I am now looking for a victim to test in our liquid nitrogen storage facility. My question is what is the strangest hardware survival you have seen."
