Forget the spin? How do you make a droplet bounce?

[@GoingtoHecq]

The surfaces are hydrophobic, the the water won't attach to them.
As a result the water maintains its own surface, and since water has surface tension, the surface of the water pulls back into itself, making it act like a bouncing kickball.

[@MikeGrattan]

From the linked story: "Controlling how liquid drops bounce off a surface may be useful in many areas such self-cleaning surfaces, deicing applications, or for mixing different materials."

[@paullelyukh2422]

you can control the hydrophilic/hydrophobic effects of the surface in specific areas using microscopic structures, this could have applications in microfluidics, printing stuff

[@nickq8093]

The surface in general is hydrophobic: water won't stick to it.
Think of the droplet as a somewhat self healing water balloon. A normal non-hydrophobic surface acts like it has lots of hooks and curls which as the surface of the water spreads out and then tries to retract on result in the drop tearing itself completely apart.
the hydropohbic surface instead acts like it is completely smooth, and as a result the water droplet is able to stay intact.
Now, the researchers created a hydrophillic (water will stick to it very strongly) pattern using thin lines on the hydrophobic surface. This patter causes the surface tension of the droplet to pull the droplet in a specific way, while doing only so much damage that it can still heal itself.

So I take it they coated the plate with a hydrophobic coating but masked off the shapes in blue from the pictures so the drops would only stick to the masked tracks, which caused the drops to behave in different ways depending on the masked shape.

This is actually really interesting. Since most of the surface is hydrophobic those small patches that actually let the fluid stick kinda attract it and let you manipulate the waters movement through that.

[@frost3193]

Next time , make them water droplets spin like fidget spinners

[@suruxstrawde8322]

Looks like they're using a hydrophobic surface with radially symmetric tracks to guide it. Interesting idea to use water's connectivity for that, they could make surfaces with those on them in a pattern to make any water on them fall in a specific direction.

What's fascinating to me is when there is only a single side that has the special coated lin, that the drop eventually jumps out in that direction. I would have thought that it would have ended up splashing away from the coated line.
