Skier safety

Technology keeps making athletes better able to compete. (via DQ)

The resulting material exhibits a material property called “strain rate sensitivity”. Under normal conditions the molecules within the material are weakly bound and can move past each with ease, making the material flexible. But the shock of sudden deformation causes the chemical bonds to strengthen and the moving molecules to lock, turning the material into a more solid, protective shield.
