    "abstract": "We present an experimental study of the motion of a solid sphere falling\nthrough a wormlike micellar fluid. While smaller or lighter spheres quickly\nreach a terminal velocity, larger or heavier spheres are found to oscillate in\nthe direction of their falling motion. The onset of this instability correlates\nwith a critical value of the velocity gradient scale $\\Gamma_{c}\\sim 1$\ns$^{-1}$. We relate this condition to the known complex rheology of wormlike\nmicellar fluids, and suggest that the unsteady motion of the sphere is caused\nby the formation and breaking of flow-induced structures.",
