How Was the Gun Invented?

A ninth-century Taoist alchemist is trying to live forever. He mixes saltpeter, sulfur, and charcoal in a stone furnace, convinced he's found the key to immortality. Instead, his workshop goes up in a wall of fire. He didn't find eternal life — he found gunpowder, and he had no idea he'd just invented the deadliest technology humans would ever build. In this video, you'll trace the thousand-year chain from "fire medicine" to modern firearm — the fire lance strapped to a spear, the world's oldest confirmed hand cannon serial-numbered before most of Europe had guns at all, and the 1453 siege where cannons brought down walls that had held for a thousand years. You'll see why every early gun's real problem wasn't the explosion, it was lighting it — and how a clamp called the matchlock, a spinning wheel called the wheellock, and a French gunsmith's flintlock each solved it, one flaw at a time. You'll meet a Scottish minister who reinvented the firing mechanism because he was sick of losing ducks, the rejected patent that built Smith & Wesson's fortune instead of Colt's, and Hiram Maxim, who finally asked what happens if the gun reloads itself.
