Well?

Well?

maybe 3 or 4

We had this thread yesterday. 1 if the flow of water is fast, 3, if it is slow.

3 will

The tap is dripping
therefore 3

One.

None of them will be full, forgot to pay the water bill, so it's getting cut off

3 and 4, simultaneously

it might depend on the speed of the water flow. in theory 3 and 4 should fill at the same time, but I think if there's a constant flow going from 2 to 3 then 3 might be full before the water has time to balance out to 4
