High-speed camera captures a fluid behaving like a solid

By itself, the study revealed what was possible with the material. You could turn the friction (and thus the fluid state) “on and off like a switch” just by varying the pressure.

However, Swansea University also suggested this could have a significant impact on engineering going forward. Scientists are already hoping to use DST for soft body armor, dynamic speed bumps and other products that could change properties on demand. Don’t be surprised if high-speed cameras become a mainstay of some engineering teams as a result.
