Guns and bullets are not to everyone's liking, but it is the near-extinct ancient technology that makes this odd sight worth a visit. It's all about gravitation. Molten lead is poured from the top of an old brick tower. By the time the drops reach the bottom, they solidify into perfectly round balls which subsequently get separated by size, mixed with graphite and packaged into neat boxes. You won't see the actually process – which is both unsafe and unhealthy – but they'll turn on century-old separation machines for you, let you climb the tower and – if you wish – shoot at beer cans from a pneumatic gun.
