'Witch Bottle'

I was just reading about this earlier in my book Witchcraft by Eric Maple.

During the 17th century in England, someone urinated in a jar, added nail clippings, hair and pins, and buried it upside-down in Greenwich, where it was recently unearthed and identified by scientists as being the world's most complete known "witch bottle."
