  Transport of liquid drops in fibrous media occurs in various engineering
systems such as fog harvesting or cleaning of textiles. The ability to tune or
to control liquid movement can increase the system efficiency and enable new
engineering applications. In this Letter, we experimentally investigate how
partially wetting drops on a single fiber can be manipulated by vibrating the
fiber. We show that a sliding motion along the fiber or a dripping of the drop
can be triggered by standing waves. We identify the conditions on the drop
volume, the fiber tilt angle and the amplitude and frequency of oscillations to
observe these different behaviors. Finally, we experimentally illustrate that
vibrations can be used to control the transport and the collection of water
drops along a fiber using a combination of the sliding and dripping
transitions.
