- Coalescence of large scale emulsion droplets
- How to split a droplet in two (the diameter of the tubes is 350 microns).
- A soap film formed by accident while measuring surface tension. Note the ultra-thin portion of the film near the top as the liquid in the film drains downward.
- Beautiful colors from light interference in a tiny soap film.
- Lowering the focal plane through Pickering emulsion droplets
