We conclude our series of articles on experiments in fluid dynamics by listing the materials and methods employed, as well as discuss a few experimental techniques which were not considered in earlier articles. Several books on flow visualisation [1, 2] are available which the reader may wish to refer.
In this series of articles, the author discusses various phenomena in fluid dynamics, which may be investigated via tabletop experiments using low-cost or home-made instruments. The fifteenth article in this series demonstrates some fluid instabilities.
In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.

In this series of articles, the authors discuss various phenomena in fluid dynamics, which may be investigated via tabletop experiments using low-cost or home-made instruments. The first article in this series is about the salt oscillator — a hydrodynamic curiosity.
We exhibit results from oscillatory extensional deformation of microscale filaments of glycerol and polydimethylsiloxane (PDMS) using a microextensional rheometer (Rao et al., Rev Sci Instrum 84(105107):1–9 2013). We decompose the tensile stress in the symmetry plane of the filament into a bulk stress and a surface tension-induced stress. Pipkin diagrams using Lissajous figures show the sample response...
Regenerated silk fibroin solutions (RSF) are produced by dissolving degummed silk fibers in water. We have observed that RSF solutions at a concentration less than 15 % by weight exhibit an unusual gel-like response in conventional shear rheology measurements. At higher concentrations, the response is predominantly viscous (or liquid-like). We have probed this counterintuitive behavior of silk fibroin...
