High speed camera captures liquids as solids

Scientists use high-speed cameras to capture the "invisible" world to the eye - those objects that

moving too fast. This time, researchers at Swansea University have used a camera that records 1000 frames per second for the first time to examine liquids in separate frames, where they appear as solids. To do this, the team placed a liquid mixture of cornstarch and water in a narrow vessel and exposed it to pressurized air. This resulted in beautiful clumps as the liquid spread - they created patterns and "cracks" that scientists could fix.

Such an experiment has not yet been performed with liquid. It can affect how researchers study liquids.

Research can show material properties andhow it behaves in different environments. By changing the state around, scientists can turn friction or fluid state on and off by simply adjusting the pressure.

Swansea University has also suggested thatthis experiment to influence the further development of technology. These cameras can be used to design soft body armor, dynamic impact loads, and other products that can change properties on demand.
