Poland’s Military Institute of Armament Technology in Warsaw has been skunk-working on liquid body armor. Specifically, non-Newtonian Shear Thickening Fluid-based body armor. “Shear-thickening fluids, unlike other liquids, harden when struck by a strong impact,” popsci.com reports. “With shear-thickening fluids (affectionately known as oobleck), the bullet’s force is absorbed by the liquid, then dissipated outwards through the fluid medium.” Previous attempts at oobleck body armor fell afoul of weight restrictions . . .
