Working with hydrogel spheres for laser sheet imaging, also known as refractive index matched scanning, can be made easier with the content of this work.

If you wonder how to make well controlled hydrogel beads, look no further. Or rather, look here.

And Kalman Migler is a pleasant person to talk to :).

First try worked already. Probing the interaction between substrate curvature and instabilities in thin films. On a flat plane, a hole in a fluid collapses symmetrically, but on cylinder the front is unstable. What about the intermediate case?

Long story short: extracting power law exponents from even very clean numerical data is hard, but there are some good tricks around :). Do check the erratum that fixes a small, strange but possibly very confusing typo that crept in…

How to mix very viscous fluids? Add some particles while stirring. Ice cubes may work but simple glass beads also work just fine. Thanks Vittorio for contributing.

Not quite accurate enough for a plate, but the solvent trap works.
