Somehow? How?


Only thing I can guess is that maybe someone shook the gadget and the
parts rattled against each other. I'm remembering how as a kid holding
an iron rod in your hand and hitting the end with a hammer would shake
up the atoms so they lined up with the earth's magnetic field and the
rod became a weak magnet.
