From AAAS ScienceNOW:

So-called non-Newtonian fluids are the stars of high school science demonstrations. In one example, an ooey-gooey batter made from corn starch and water oozes like a liquid when moved slowly. But punch it, or run across a giant puddle of it, and it becomes stiff like a solid. Pour it on top of a speaker cone, and the vibrations cause the fluid to stiffen and form strange tendril-like shapes. Now, a group of college students has figured out a new use for the strange stuff: filler for potholes.

Clever! The prototype, from a group Case Western Reserve University undergraduates, consists of a waterproof Kevlar-reinforced pouch filled with shear-thickening fluid that can be simply dropped into a pothole to effect a quick fix. Under its own weight, the fluid is Newtonian and flows to take the shape of its container (i.e. the pothole). But when a car drives over, it thickens in response and supports the weight. Apparently it works very well as a temporary fix, but questions remain about long-term and cold-weather performance.
