a clipping of the article.

In addition, Armor Holdings, Inc. has developed a product that is similar to the Army-MIT program, a "Shear-Thickening Liquid" armor additive produced from a mixture of polyethylene glycol, a polymer found in laxatives and other consumer products, and nanobits of silica, or purified sand. When struck with a significant impact, the armor stiffens instantly into a shield, then reverting to its liquid state just as fast when the energy from the projectile dissipates. The new armor, originally envisioned to be spread on like peanut butter, is instead sprayed onto Kevlar in ultrathin coats. Armor Holdings plans to begin promote this new armor in 2007, but it is not sure if this will be used as a substitute for the Army's Survivability Vision.

Sort of like corn starch and water, but much better.

Kinda sci-fi scary but really cool, just have to make headshots I guess.
