View source for Silver, Salt, Holy Water Test

As many supernatural creatures such as demons and ghosts are vulnerable to [[silver]], [[salt]] and/or [[holy water]], these substances are used as a test by hunters to help determine whether someone is human. It is a pretty fallible method -- see below for the many times when it failed to detect monsters.
