Scientists stretched a liquid and it snapped like a solid

Scientists have discovered something that seems almost impossible: under the right conditions, ordinary liquids can snap apart like solid objects. In experiments, researchers found that when certain liquids are stretched with enough force, they don’t just thin and flow—they suddenly fracture with a sharp break, much like metal under stress. This surprising behavior appears to be tied to viscosity, not elasticity, challenging long-held assumptions about how liquids behave.
