How Did Humans Discover Dynamite?

For a thousand years, humanity had only black powder to move mountains—and it was hitting a brick wall. Then chemistry created nitroglycerin: an explosive so astronomically violent it could shatter granite, but so unstable that a dropped crate could level a city block. It took the death of an inventor’s brother, a global wave of catastrophic explosions, and an accidental leak into microscopic fossilized algae to create the stable clay that blasted transcontinental railroads, cut the Panama Canal, and funded the Nobel Peace Prize. In this video, we deconstruct the terrifying origin of dynamite: how an uncontrollable liquid was tamed by prehistoric shells to engineer modern civilization.
