Elastocapillary Winding

Written by

in

A fiber sitting atop a bubble spontaneously winds around the bubble's cap.

The energy necessary to bend the fiber comes from the reduction in free energy the system has from winding.

When "unbridged" the fiber sits atop the liquid film. When "bridged", it sinks into the liquid so that the fiber touches air outside the bubble and inside it.
