kjh1's Journal: Superhero Body Armor Coming Soon

Armor Holdings Inc. plans to start selling their "liquid armor" next year. From the Business Week article: "it's a mix of polyethylene glycol, a polymer found in laxatives and other consumer products, and nanobits of silica, or purified sand. Together they produce a "sheer-thickening liquid" that stiffens instantly into a shield when hit hard by an object. It reverts to its liquid state just as fast when the energy from the projectile dissipates."
