It should. The principle is very basic physics. Surface tension keeps the fluid in contact with the solid surface. If the force required to maintain that connection is greater than the linear force of the flowing liquid, it will detach. By adding a relatively sharp bend underneath the rim, the fluid must overcome the forces trying to separate it from the surface (gravity and its own momentum) to stay in contact, which it can’t do using the surface tension of fluids as thin as wine or water (or,…
