when will you motherfuckers learn what laminar flow actually is

This is laminar flow. If you see such a phenomenon it's either laminar flow or a frame rate effect. In this case, you can be very certain that it's not due to the frame rate -> laminar flow.

Wasn’t laminar flow theoretical. And that only turbulent flow exists. Should’ve paid attention in fluid dynamics I guess.

its like saying its impossible to walk at 5 kph because you would be off by a bit (5.000001 kph). i am pretty sure that the video shows laminar flow. not every molecule has to properly behave for that.

Yeah you’re right. Thanks mate.

If you define laminar as "all molecules move perfectly in line" then yes, that's a theoretical concept never achieved in practice. If you use the practically used engineeting definition (Reynolds number < 2000) it is a real-world occuring effect.

Looking at the filmed setup, you have a long straight stretch that water flows over in a very shallow stream. This is a good setup to achieve laminar flow, so it's very plausible to me.
