The stream from the bottom of the bottle becomes short when the bottle is filled from above

[Mihal]

the homogenous part of the stream becomes too short when the bottle is being filled from above. I need the longer stream when the bottle is being filled, such is shown on the photo where the bottle is not being filled.

this is needed for the kelving generator, in the design of which the lengths of the components are important. In this case, the length of the jet is the length from the nozzle to the inductor, and it must be specific and not changing during its falling. So I don't want it to shorten when I pour water into the bottle from the tap or hose!
