Loved it, thanks.

That was was awesome!!! thank you very much. So happy to see you back.

I put mi glasses on and i saw that several times. I am so pleased you are back!

So beautiful and interesting! Thanks!

one ring to rule them all

[@MrRedwires]

Very pretty! This makes me wonder if there are any worthwhile applications of the drop-splitting caused by the superhydrophobic cone. For microfluidics, I think there already are fairly good mechanisms to create droplets within the microfluidic chamber, rather than needing to accelerate the droplets and let them impact a surface... However, that ring shaped impact that formed a bubble seemed rather neat. Maybe a high-efficiency tiny soap bubble generator? :>

This is fascinating, thank you for sharing. Is it possible to have stable vortex rings of fluid in air, similar to smoke rings?

[@arkenson532]

It is not possible because surface tension tries to minimize the surface area of the droplet and thus drives the ring into spherical droplets, either by collapsing into a droplet (like the earlier clips in the video), or by breaking into multiple droplets. In the case of smoke, there is not surface tension since smoke and air are miscible, and thus it can be stable for a long time.

How much FSP does the camera set？
