Hello, i am trying to remember the name of the guy who created a water fountain that seemed to recycle its own water by using pressure or something in order to siphon it back up to the start. I can't remember the era this guy was from but i am pretty sure it was before electricity so probably several centuries ago. I saw it on the history channel last year if that helps. I do not remember him having to do anything to make it work. It seemed like the water fell in a large bowl which emptied out to closed bowl beneath which had a tube connected to it that lead back up to the start. I am thinking that maybe the large bowl had enough water in it pushing down on the water beneath that the water beneath traveled back up to the top. any ideas on the name? or how to make a fountain like this? i.e. a fountain that does not require electricity or pumps to continue operating.
