Fragments & Bullets

"There is some kind of, what I may call, tradition in our family to collect bullets that fall on our house. It goes back to some twenty years ago or more. In fact, it is nothing more than a small plastic box in which one finds bomb fragments and bullets of different kinds & shapes. The other day I decided to weight this collection. Its weight was more than half a kilogram (I think it is something around one pound)."
Ibn Alrafidain
