Years later, a young girl asked Maya, "Why didn’t you use a stone or a piece of wood like everyone else?"

Maya replied: "Because I watched. A stone would grind the iron down further. Wood would swell and crack in the frost. Glass—broken glass cuts. But a whole bead? A whole bead has no sharp edges. It is hard, smooth, and patient. The problem wasn’t strength. It was shape."

Maya said nothing. She went home, opened a small birchwood box, and took out a single glass bead—a deep, swirling blue, no bigger than a chickpea. It had been her grandmother’s. Everyone thought it was a useless trinket.

Panic stirred. Some suggested abandoning the well. Others blamed Maya for not predicting the rust.

The villagers drew water that evening, and for three more winters, until a new blacksmith arrived.
