Gunpowder is the most destructive tool ever devised by Man. It has forever changed the face of warfare, allowing an untrained peasant to kill a highly disciplined, professional soldier with virtually no effort. Scholars have begun to speculate: could this formidable development destroy the concept of chivalry, perhaps even that of mercy? Only time will tell, and this troubling debate has only just begun. Also, gunpowder is used in fireworks to celebrate various occasions, and if you light off even a quite small one in your hand, it will hurt very, very badly. I cannot overstate how unthinkably horrible the pain is.
