sciencehabit writes in with a link about a group of students who have come up with an interesting idea about how to fill potholes. "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. Now, a group of college students has figured out a new use for the strange stuff: filler for potholes."
