Scientists figured out how to write in water
- galaxyLogic 3y agoInteresting but what is it good for?
- fnordpiglet 3y agoWriting in water
- chrisfosterelli 3y agoIs this not a solved problem? https://scubagearcanada.ca/slate-glow/ https://scubagearcanada.ca/slate-glow/ EDIT: I guess the article is literally writing in water, not writing on something while in water.
- hinkley 3y agoOr writing on something with water, which is also solved. https://buddhaboard.com/ https://buddhaboard.com/
- Calamitous 3y agoAh, reddit is leaking again.
- anon____ 3y agoThe authors write this in the conclusion of their paper: > 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. https://onlinelibrary.wiley.com/doi/10.1002/smll.202303741 https://onlinelibrary.wiley.com/doi/10.1002/smll.202303741

- xorbax 3y agoI think if you start consider what it does to enthalpy and entropy at the microscale and then consider how to use that to modify dynamics (i.e. reactions in progress) you can start to do some pretty fun things.
- tetris11 3y agoThere's a Metalocalypse episode where they use water as a new media fornat that produces superior quality sound. Science fiction into fact?
- 10g1k 3y ago"Any sufficiently advanced technology is indistinguishable from magic." Arthur Clarke.
- hinkley 3y agoTime to resurrect Keats? Headstone: "Here lies one whose name was writ in water." Alternate reaction: The example should say "John Keats" instead of 'TUDa"
- Helmut10001 3y agoI only know Keats from the Hyperion Cantos, where "he was resurrected [in 2737] in multiple cybrid incarnations". He was also the name giver of the book series. [1] Thank you for this reminder! [1]: https://hyperioncantos.fandom.com/wiki/John_Keats https://hyperioncantos.fandom.com/wiki/John_Keats
- mellosouls 3y agoI scanned the article for Keats and no mention, poor form ArsT. 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.
- hinkley 3y agoTo be fair the scientists are German. Probably not up on English literature. 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?
- xorbax 3y ago"John Keats, John Keats Please put your scarf on."
- TowerTall 3y agoI has always been super easy to write in water if you use dry water. /s 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. https://en.wikipedia.org/wiki/Dry_water https://en.wikipedia.org/wiki/Dry_water

- kazinator 3y agoYou can write in water by using a marker to write on a piece of glass, and then carefully submerging the glass, so that the writing lifts off the glass and floats on the surface. I saw that on Japanese TV. https://www.youtube.com/watch?v=F4NSDttKJC4 https://www.youtube.com/watch?v=F4NSDttKJC4
- iancmceachern 3y agoYes, they also use this to print complex patterns on complex shapes, it's called hydoprinting, lots of cool videos on YouTube on that also
- flobosg 3y agoYou just reminded me of this video that I watched years ago: https://www.youtube.com/watch?v=Vyga8VMWXKg https://www.youtube.com/watch?v=Vyga8VMWXKg

- pmontra 3y agoFrom the article > 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
- rootw0rm 3y agoThey put a whole house on a little tittle.
- dieantwoord 3y agoI had such a space pen about 20 years ago and it was already possible to write with it under water: https://en.wikipedia.org/wiki/Space_Pen https://en.wikipedia.org/wiki/Space_Pen
- iancmceachern 3y agoPencils also work well, there are pencils specifically designed for it. https://www.xit404.com/collections/aqua-pencil-solo-packs https://www.xit404.com/collections/aqua-pencil-solo-packs It's what scuba folks use.
- iancmceachern 3y agoSolved problem, scuba pencils: https://www.xit404.com/collections/aqua-pencil-solo-packs https://www.xit404.com/collections/aqua-pencil-solo-packs
- trehans 3y agoIf you read the article, it addresses this exact scuba pen, and why this is solving a different problem.
- iancmceachern 3y ago(For others) It's the substrate, they're trying to write in fluid, with no "paper".
