  • Spiral and zigzag trajectories of rising bubbles and falling leaves represent some of the path instabilities commonly observed for objects moving through fluids. Here, Mathai et al. show that the moment-of-inertia plays a crucial role in triggering such path instabilities for rising spherical particles.
