At Home, Do-It-Yourself Fluid Mechanics

In Physics of Fluids, 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.
