surface tension

In a scientific context, this term describes a specific physical property of liquids where molecules on the surface are pulled inward, creating a skin-like effect. It is a technical term used primarily in physics and chemistry to explain phenomena like capillary action or the ability of certain insects to walk on water.

When used figuratively, the term describes a fragile social equilibrium. It suggests a situation where conflict or anger is present but suppressed, creating a feeling of instability. The imagery implies that the slightest provocation could "break" the surface, leading to an immediate and visible eruption of hostility.
