Why the drop remains a drop – the surface tension
The surface of a liquid can be compared to a stretched, elastic film. Liquids, including liquid hot-melt adhesives, strive to keep their surface area small through the molecular forces that occur.
As the sphere has the smallest surface area in three-dimensional space, drops are formed. Thus, the liquid has the smallest interface to the surrounding gas (for example, the room air).
