Double-stranded vibrot chains have an affinity for chiral vibrot fluid interfaces. (A) Double-stranded vibrot chain of geometry 2×6. (B) Experimental snapshots with a 2×14 chain at three observation times. Orange lines are connectors. (C) Evolution of the distance between the centers of mass of the left-handed and right-handed fraction of vibrots (orange curve), distance of each fraction from the chain’s center of mass (purple and green).
