Duck

One form of testing if a woman was a witch was to tie her to a pole and plunge her into the water. If she were a witch her witchcraft would prevent submergence. Otherwise she would merely drown and the authorities would be obliged to apologize to her bereaved family. Towns with civic pride set up permanent ducking stools for this vital research.
