Researchers in the UK studied the properties of liquids using a high-speed camera. It removes so quickly that liquids are more like solids. In the future, this method will be used for the design of materials that experience shock loads.
Scientists use high-speed cameras to capture the “invisible” world – those objects that move too fast. This time, researchers at the University of Swansea used a camera that records 1000 frames per second for the first time to examine liquid 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 the properties of a material and how 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 also suggested that this experiment would have an impact on 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.
