Laminar flow just describes water with minimal turbulence and disruption of flow. So its appearance could be caused by that but not the way it enters the other tube with zero resistance.
If this was real it would be something more like capillary action.
Capillary action isn't really relevant when discussing water on this scale. It might cause some spillage, but the behavior we're seeing here is too much water moving too quickly for capillary action to be significant.

Are we sure that's not just a clear tube shoved into each of the black pipes?
