The cohesion and adhesion of water necessitates that it has enough molecules to interact with each other. Any time water is divided, the forces that allow it to make things wet either have to be ignored or the water has to be separated enough that each part is no longer in contact with the other. So water either can’t be touching itself because it’s separate and can’t make something it’s not touching wet or it’s still a singular conceptual entity doesn’t change its own properties simply by existing.
