  1. This hat seemed to turn to stone

    At Knaresborough’s dripping well, Victorian visitors saw everyday objects hanging beneath mineral-rich water.

  2. The water was building a shell

    Minerals left by the dripping water formed a hard coating around each object, following its shape.

  3. A stone coat, not a stone hat

    The shape stayed familiar because the deposit formed around it. The apparent transformation was encrustation.

  1. The pantry is alive

    Some ants store liquid food inside their own bodies. Their swollen abdomens turn living workers into the colony’s food reserves.

  2. These workers hang from the ceiling

    Storage workers cling to the roof of a nest chamber. Other workers bring them food, filling the enlarged crop inside the abdomen.

  3. One colony. Different jobs.

    Some workers collect the food; others store it. The colony’s supply is held in the bodies of its own workers.
