At home, do-it-yourself fluid mechanics

Scientists describe their work on an at-home study of rheology, which is used to study the way non-Newtonian liquids or semisolid substances flow. The projects assigned to students had two parts: gathering qualitative visual evidence of rheological properties and taking quantitative measurements. The students checked for four behaviors — shear thinning viscosity, viscoelasticity, shear normal stress difference, and extensional viscosity — and even without access to laboratory rheometers, they developed creative and unique ways to carry out their measurements.
