The scientist and his team typically focus on the flow of sand, gravel and other industrial materials. "It really is like a liquid if you move it slowly, but it does everything you expect of a solid if you play with it quickly," Kamrin said.Īfter seeing a scientific talk about oobleck's properties, Kamrin and his colleagues launched a "very healthy" internal debate over how cornstarch and water might differ from other wet, granular materials. When you run your fingers slowly through cornstarch and water, it acts like a liquid, but apply rapid force, and it solidifies, bends and even tears. Oobleck is a non-Newtonian fluid, a term for fluids that change viscosity (how easily they flow) under stress. ![]()
