you see Western witch-hunters just used "a tablespoon" of piss but in Japan they measured it out precisely.
I remember pondering this when I learned about the real witch hunters of the 16th century. They had "perfected" techniques like baking pies with dog piss to catch witches, precisely honing in on just the right amount of dog piss. It was all made up! But to them it was as much a science as astronomy.
