Wake-Induced Oscillatory Paths of Bodies Freely Rising or Falling in Fluids: Supplemental Video 2a

A supplemental video from the 2012 review by Patricia Ern, Frédéric Risso, David Fabre, and Jacques Magnaudet, "Wake-Induced Oscillatory Paths of Bodies Freely Rising or Falling in Fluids," from the Annual Review of Fluid Mechanics.

An approximately oblate spheroidal air bubble with χ ≈ 2.0 and Re ≈ 760 rising in water (the sphere of same volume would have a diameter of 2.5 mm). The path is close to a planar zigzag. From experiments by Riboux et al. (2010).
