Have you ever mixed corn starch with water? If you have, you probably noticed how it oozed like a liquid when flowing across a surface, yet hardened like a solid if you suddenly struck it. That’s because the corn starch/water mixture is what’s known as a non-Newtonian fluid – the particles it’s composed of slide past one another easily when moving slowly, but jam against each other when forced to move quickly. Recently, a group of students from Cleveland’s Case Western University encased such a fluid within sturdy bags, to create a simple product that could be used to temporarily fill potholes in roads.
