If an air bubble displaces a viscous liquid in a narrow gap between two plates, the interface between the bubble and the liquid tends to lose symmetry. This will lead to the formation of interfacial patterns called viscous fingering that are similar to snowflakes and dendrites. We will show how by tinkering with parts of the system (for example, by making the plates elastic), we can discover a surprising range of new phenomena: from suppression of viscous fingers to fluid-incused wrinkling of elastic sheets.
