Abstract

A counterintuitive submerged floating of objects lighter than the supporting liquid was observed. Polymer plates with dimensions on the order of magnitude of the capillary length were hydrophilized with cold air plasma were floated in an "under-liquid" regime (totally covered by liquid) when immersed in water or glycerol. Profiles of liquid surfaces curved by polymer plates are measured. We propose a model explaining the phenomenon. The floating of Janus plates is reported.
