today's flush toilets. A modern engineer could say it
was an early use of the feedback principle so important
in automation.
when a worshiper put a coin in the slot, it automatically
produced a measured amount of holy water.
The coin fell onto a small pan hung from one end of a
delicately balanced beam. Its weight caused the beam
to dip; the beam's opposite end rose, opening a
stopper valve and allowing the holy water to flow out.
When the pan carrying the coin had been tilted
enough, the coin slid off. Free of its weight, the down
end of the beam bobbed upward again and the up end
