We have developed and commercialised a device to measure the viscosity of low viscosity, Newtonian liquid. This involves smearing a liquid drop on a glass slide and measuring the dimensions of the spread of the drop. Using the fluid flow equations, we have shown that a balance between the viscous and capillary forces determine the dimensions of the spread. We would now like to extend this technique to measure the rheology of shear thinning liquids and even viscoelastic liquids. We are looking for a student who likes to tinker and think. No other prerequisite is needed.
