Scientists figured out how to write in water

Dry water or empty water, a form of "powdered liquid", is an air–water emulsion in which water droplets are surrounded by a silica coating. Dry water consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid. The result is a white powder.
I saw that on Japanese TV.
Headstone: "Here lies one whose name was writ in water."
Alternate reaction:
The example should say "John Keats" instead of 'TUDa"
According to legend this is a bitter reference to his self-perception as somebody dismissed cruelly by critics, his work to be forgotten and who may as well have never existed.
It’s such a profound statement I don’t think it’s easy to forget once you know it. But then who knows what Keats’ epitaph was? Except English lit majors and Dan Simmons fans?
> Full Width at Half Maximum (FWHM). The FWHM increases slowly and at continually slowing pace with increasing time. Notably, even after some ten minutes, the linewidth has increased from 40 µm to merely 90 µm

It's what scuba folks use.

EDIT: I guess the article is literally writing in water, not writing on something while in water.
> Thus, we anticipate that our results and conclusions are valid for a broad class of systems and may open routes to many future enterprises including the structuring of fluids, the visualization of chemical traces, the assembling of functional objects like actuators or drug carriers, information storage, and numerous artistical applications. Finally, our results could also be used to prepare desired initial states for future colloid experiments, e.g., on collective diffusion. Drawing fine lines, durable patterns, and individual letters into water was only the first step.
It's the substrate, they're trying to write in fluid, with no "paper".
