This episode uncaps the surprising history of the tansan—the humble metal crown that sealed our childhood sodas and our uncles' beers. We trace its journey from an unlikely Japanese brand name to the prized currency of sidewalk games like Tatsing. Learn how this piece of industrial waste was transformed into the sound of Christmas karoling and, tragically, the explosive center of the 1992 Pepsi "Number Fever" scandal. Join us as we explore the rise and fall of this accidental Filipino icon.
