Droplet impact: Bouncing from beds of nails
 | Slow motion of a drop hitting a superhydrophobic surface. |
Water droplets impact and splash on a solid surface in many ways, but on superhydrophobic surfaces the droplets can impact, spread and rebound with startling effectiveness. On superhydrophobic surfaces it is possible for a droplet to rebound completely and display fascinating oscillations as it does so. At higher speeds droplets can impale on the Fakir's carpet and send jets down the lines of symmetry of the substrate. Read more about the work of Professor Quéré and colleagues at Physics World.
