  We investigate the interaction between an infinite cylinder and a free
fluid-fluid interface governed only by its surface tension. We study the
deformation of an initially flat interface when it is deformed by the presence
of a cylindrical object, tilted at an arbitrary angle, that the interface
"totally wets". Our simulations predict all significant quantities such as the
interface shape, the position of the contact line, and the force exerted by the
interface on the cylinder. These results are compared with an experimental
study of the penetration of a soap film by a cylindrical liquid jet. This
dynamic situation exhibits all the characteristics of a totally wetting
interface. We show that whatever the inclination, the force is always
perpendicular to the plane of the interface, and its amplitude diverges as the
inclination angle increases. Such results should bring new insights in both
fluid and solid mechanics, from animal locomotion to surface
micro-processing.-processing.
