Scientists Discover Liquids Can Snap Like Solids

Researchers from Drexel University and ExxonMobil have discovered that simple liquids can fracture like solids when subjected to strong forces. This finding has implications for various fields, including 3D printing technology and biological systems, and challenges our current understanding of fluid mechanics.
Researchers have found that liquids can snap like solids when pulled with enough force. The discovery was made by a team from Drexel University and ExxonMobil, who conducted experiments on viscous liquids. They used a high-speed camera to observe the liquids between two metal plates, applying various forces. The first snap occurred in a tar-like hydrocarbon blend liquid, and the same breaking point was found in a different liquid, styrene oligomer. The team believes that viscosity plays a crucial role in this phenomenon. Thicker liquids can crack even when pulled slowly, but the amount of force needed is the same regardless of viscosity. This discovery has implications for fields like 3D printing and soft robotics.
