A new pothole repair method invented by students uses a non-Newtonian fluid as its major component.
Non-Newtonian fluids react differently to various forces, changing from liquid to solid under pressure. The students, from Case Western Reserve University in Cleveland, created a repair material made of plastic bags filled with a specifically created non-Newtonian fluid. The bags are flexible enough to allow police or road crews to simple lay the bag in the hole, where it then stiffens to fill the hole when a car drives over it.
The non-Newtonian pothole repair bags are meant to be used as a temporary measure, lasting a few weeks until crews can make proper repairs.
