This rough stone flying under a magnet is a natural magnetite coming from a high valley of Hungary at 1000 meters in the Börzsöny mountains. You can catch it in your hand and put it back flying for ever: all the Iron oxyd, Magnesium, Zinc and Manganese which it is made, won't alterate in the next centuries...
