Local politicians probably get more calls on potholes than anything else. But these days, with budget shortfalls and with tax hikes about as popular as the Jonas Brothers, it seems that there are more potholes -- and the ones that are there are even larger.
Maybe it’s time for an additional solution that can fill the gap (pun intended) when road crews can't get to all of the bone-jarring banes of driving existence. Students at Cleveland's Case Western Reserve University have come up with an alternative, and in April they took the top prize in a competition sponsored by global materials company Saint-Gobain, in which the objective was to use simple materials to create an unconventional product that solves a common problem.
Because a byproduct of potholes is puddles, the team deduced that best way to solve the problem was to fill them with a non-Newtonian fluid. Non-Newtonian fluids respond differently to shear than Newtonian fluids, acting as a solid upon impact. The students filled a Kevlar bag with a nontoxic goop called "oobleck" to win the prize. (Without the force, oobleck is like a sack of fluid, simply conforming to the contours of the pothole and creating a level surface. A video of the solution is found below.)
