What is happening here is the water is allowed a steady flow without any change in pressure. It’s like an open top container with a lot of water in it so the hole doesn’t need to compensate pressure by sucking in air, which is what make the usual wiggly water effects you’re used to.
Yep. This is called laminar flow. It has nothing to do with the camera’s frame rate or shutter speed like what some people are claiming in the notes.
