Castles then fell out of favor because the Sarasons invented the hand grenade using gunpowder they got from the early Chinese invention and made a hollow clay ball which was then heat treated so it was like ceramic. They put in gunpowder down the top and also put in a fuse. Lit the fuse and then threw it over the walls and they exploded like a dirty bomb as shards of ceramic would break away as it exploded inside the castle. It could also have small pebbles in it. Archeologists found in a cave in Spain a cache of 60,000 hollow ceramic balls that look like a U.S. grenade. While holding it it occurred to one archeologist what it was as they served military time.
