Siphoned Heron's fountain

[Ghost]

thanks, see if any of the above ideas will work.
but why the library?

containers are equal and hoses are equal, just different water level.
one container is sealed and the other has an open top.

Water can't flow uphill, which is to say you cant make water flow from a lower level to a higher level, The outlet of the siphon must always be below the level of the water you are trying to drain.

The pipe will siphon the full container into the empty one but stop as soon as the empty one has the same water level as the now half full one. The empty or almost empty one will never discharge water into the more full one. That is unless you put the more full one below the empty one. Imagine the empty one on a shelf and the full one on the floor.

But go ahead and try it. Its a great idea and helps teach some basics of hydraulics. A length of plastic tube and some old plastic soft drink or perhaps milk containers will do.

I have spent countless hours musing over similar arrangements but could not make one work theoretically. hence never spent a cent.

  Ghost,
I only have a basic smart phone.
There is one other aspect to this and that's work equals mass times distance.

where does the air go in the almost empty container?
it seems as if the air will stay in there and not leave room for extra water to come in.
so how is extras water going in to balance the system to a stop?
