Scientists stretched a liquid and it snapped like a solid
This image was generated by AI and may not depict real events.
Researchers at Drexel University have discovered that ordinary liquids can snap apart like solid objects when stretched with enough force, challenging long-held assumptions about fluid physics. This behavior is tied to viscosity, not elasticity, and could lead to new ways of controlling liquids in various applications.
Scientists have found that liquids can behave like solids under certain conditions. When stretched with enough force, they can suddenly fracture with a sharp break. Researchers at Drexel University made this discovery while studying simple liquids. They observed that tar-like liquids snapped apart during an extensional rheology test. The team used a high-speed camera to capture this behavior, which is typically seen in solid materials. The discovery could lead to new ways of controlling liquids in applications such as hydraulics and 3D printing.
