Tying Water in a Knot

Reporting in the journal Nature Physics, William Irvine and Dustin Kleckner, physicists at the University of Chicago, describe the knotted fluid vortex they created in the lab -- a scientific first, they say. The knots resemble smoke rings -- except these are made of water, and they're shaped like pretzels, not donuts. Understanding knottiness has extra-large applications, including untangling dynamics of the sun.

Rename this video "scientists dominate vaping trick contest."

"You can't have the sun in your lab"

Not with that attitude.

"Rings spinning in opposite directions start to get closer to one another"

as I learn more, some properties of water unveiled to be analogous to those of electricity. Fascinating.

[Logan-qinx]

the real question is, can you make a noose out of water?

Or can you...

Looks like this could even be used to better understand the shapes and movements of galaxies.

Never seen this channel before and "tying water in knots" reminds me of the pseudoscience "shaped water" thing. I was pleasantly surprised. Thank you. =] Also, as a mathematician, it would be interesting to know if any knot theory stuff applies to this. Haven't studied knot theory myself but it definitely has the outward appearance of relevance in at least visualising the knots.

amount of KNOTTITNESS????
"science"

[savybones]

OH this is why when a motor boat goes by, the water feels chunky like a million ice cubes "SCIENCE"

Sounds like something that came out of my free time when I wonder about the most random shit o-o Nice

2:30 lol only a scientist would consider "understanding the sun" to be a practical application.

[TheLordHighNoob]

THEY SAID I COULDN'T HAVE A SUN IN MY LAB!
WELL!
They were right.
Hey, I tried!
Anyone for pizza?
Or meth?
I'm just lonely, is all.

1:48 Does a naughty fluid stay not it? XD jk

WHY DID IT TAKE ME SO LONG TO FIND THIS OMFG

[Supware]

Is it possible to blow a smoke trefoil?

[stormq]

the claps at 1:20 scared the shit out of me.

[김동재-km]

Um anyone knows if the design of the 3D model is shared on a site?

[xSkitZx]

So this, a bunch of scientists think it might be related to the sun's corona because.... it looks similar?
o_O really?

[adriansaravia]

i like how there are some people worrying about globadl warming and human extinction while these guys are trying to figure out how to tie water into a knot
