Military working on liquid body armor

The US Army Research Laboratory has developed a new type of liquid body armor made out of a special liquid,
polyethylene glycol, with bullet-stopping particles suspended in it. The liquid armor actually stiffens on impact to stop projectiles, and before you start worrying about the prospect of soldiers springing leaks on the battlefield, is actually soaked into the Kevlar fabric used in bulletproof vests, holding the liquid in place.
