Fluctuations and Instability in Sedimentation: Supplemental Video 1

A supplemental video from the 2011 review by Élisabeth Guazzelli and John Hinch, "Fluctuations and Instability in Sedimentation," from the Annual Review of Fluid Mechanics. 

Shown: Sedimentation of a suspension of spheres having Φ ≈ 0.3 in a test tube at low Reynolds number, showing a sharp front between the clear fluid and the suspension (Credits: B. Metzger & É Guazzelli).
