  • The behaviour of water impacting on surfaces is crucial to many applications, including anti-icings and self-cleaning. Here, Gauthier et al.show that the contact time of drops on a straight wire decreases with impact speed in a step manner due to the fragmentation of water in evenly divided subunits.

  • A transverse wind is shown to be capable of inciting a droplet to move along a horizontal fibre due to the presence of an asymmetric wake behind the droplet. Such a perturbation can even induce repulsive interactions between droplets.

  • Water drops placed at rest on flat, hot solids are found to rotate and spontaneously propel themselves in the direction of their rotation. The effect is due to symmetry breaking of the flow inside the drop, which couples rotation to translation.

  • A liquid droplet placed on a hot surface can levitate, and moreover, self-propel if the surface is textured. Solids can similarly self-propel, which means that the properties of the liquid are irrelevant. Rather, it is the vapour beneath the drop that does the propelling.

  • It has previously been reported that hot drops impacting on a colder surface can lead to loss of surface hydrophobicity unless the surface features are very small. Here the authors find that both small and large features but not intermediate ones are able to preserve hydrophobicity.

  • The antifogging properties of a structured surface can be considerably enhanced if the feature size is small enough and if the feature shapes are cones rather than cylinders.
