Abstract
A range of fascinating flow features was observed while cleaning or filling the medicine or liquid vials in the kitchen sink by serendipity. Here, we present the formation of an open inverted bell and bell-shaped flow structures formed from the water sheet in a new geometric arrangement, hitherto unknown. When a laminar jet impinges on the surface of the liquid in the vial of marginally larger or similar diameter, an inverted open water bell is formed, which gradually changes into a flat water sheet to classical water bell as the flow rate is increased. The inverted water bell structures disintegrate by forming water ridges, which finally break down into different sizes of droplets.
