SmarterEveryDay : If you'd like to help, it would be great to get some captions for this video in your native language. At this point, there's no English. Help would be appreciated! http://www.youtube.com/timedtext_video?ref=share&v=EVbdbVhzcM4

AuthenTech - Ben Schmanke : RIP the poor editor on this project, lol :) YEARS of footage chopped down to a succinct 8 min

FR0ZENxTUNA : *When YouTube recommendation is on point*

No Ban : We get it, you vape.

Viral : who clicked on this video without knowing what is going on xD

Как снимать видео : Залипашки ))

Ryan True : I had to overcome people mocking me, I love aviation so I read books, watch documentaries and films, I read magazine's and build model aircraft, I have done RC flying, I'm currently an aircraft systems technician and I talk to aircrew where and when I can and done my first solo flight last year. 23 years it took me to get to fly an aircraft properly myself but I did it

Limondero : *_4:52_**_ - Казалось бы..._*

Jacko Jambo : 4:54 *sponsored by IKEA*

Jerry Da King : their water bills must be really high

TET2005 : That's how we gonna destroy the ICBM!

BV3D: Bryan Vines : I came for the cool vortices, and got a bonus inspirational message. Thanks!

Blue Eyed Crunchy : This is incredibly inspiring and actually gives me drive to pursue engineering. It’s so incredibly satisfying when you’re able to finally get the result you want. Thank you for this video because it actually makes me want to pursue these kind of things.

Nimo Kali : Wow, that is stunning!

DabTime : If this was somehow created in a perfect simulated environment, with no wind or anything, could it be possible that there are even smaller rings within the secondary rings that come off of the main, large ring? Like a fractal?

oskr93 : Hi, this is extremely interesintg. I would like to know if possible: -The number of outer rings coming out of the collision. -Do the numbers of rings vary with collision speed/velocity of injection of fluid, or density of fluid? Your work here is truly on another level, I just had the crazy idea of aplying the most basic for of Cymatic unduction to the pumps, would a fluid vibrating a some specific frequency affect the most simply energy form projected in the video? Many Thanks for pursuing this and cheers to more. Is there an email to contact your group?

Rare Earth : I love how your mind works. You are the best thing on YouTube by leagues. Your patience is genuinely inspirational.

DEEKSHANT SINGH : Alright, *I'll do it myself*

am Sloth : 4:41 ССлава Украине

Kevin Nguyen : I bet that what a supernova will look like

Coolfrymaster : This is cool but is there a purpose to it? Or just to renew information

SmarterEveryDay : We used a computer controlled cylinder to pump fluid behind a rubber membrane to fire toroidal vortices out of the vortex cannons. We fixed one of the vortex cannon in a stationary position, and used a multi-axis microscope stage to align a second cannon to it… which sounds incredibly easy, until you realize that DYE density was an experiment all on its own. If the density of the dye mix was lighter than water, the vortex would go up. If the dye was more dense than water the vortex would fall. We had to overcome SO MANY VARIABLES and we basically spent about 4 hours figuring each variable. Water/dye temperature differential Water turbulence Water turbidity (cloudiness or haziness of a fluid) How to reset the aquarium Cannon Spacing Cannon Nozzle Cannon Shape Dye homogeneity in the vortex itself The piston displacement volume The piston stroke speed Rubber diaphragm tension, would make one side fire faster than the other. Water or air to drive diaphram? Firing speed (too slow and they drift, too fast and turbulence tears apart secondaries) We did a complete redesign of the cannon 3 different times. The Dye loading method was changed several times At times We tried to maintain negative pressure on the cannon chamber… we also tried to put shutters on the front of the muzzle. Ultimately I decided it was ok to live with dye dripping out of the front. We had to premix the dyes and eventually we got there. It got to the point where we didn’t even really know what success looked like and always thought we were there.

CD Snider : Great video! Why didn't you just locate the original inventor of the machine?

Алексей Ружицкий : 4:42 Казалось бы, причем тут Украина

Bald Satana Sempai : 4:42 - ще не вмерла України ...

просто Бека : 4:42 казалось бы...

Practical Engineering : This is so awesome. Congratulations on getting it to work. What a video!

Banshee Ampony : This is the most amazing thing I’ve ever seen

llPro Playerll : I think I know why it works like that. Since water tries to stick together, the weak part of the paint that is spread connects to a stronger, and thicker part of the paint. Edit: I don’t know what highlighted comment means but ok Also I think the impact of the two paint bubbles make the paint flat while the outlines were thinker then inside

j b : Perfect for the opening credits of a James Bond movie.

Manuel Mouro : This is so inspiring!!!

BWX : You are promoted to mad scientist status. Congratulations.

Kayoe : Dirty sprite legendary

R : Cool video...but Earth is still flat.

Евгений Тыжнов : Может наша вселенная есть результат столкновения двух движущихся навстречу элементарных частей?

Yudis 617 : Amazing 👍

My Mate Nate : "All you gotta do is fill the tank back up and give it another shot" - best quote ever and soo inspirational! Keep up the amazing work.

박준영 : 굴절 때문에 시각 오차가 크군 구름아트하고 싶은분인듯

Sudhanshu Chaurasia : interference of two waves might be explanation of this. constructive interference occurs there where the outer ring are formed and destructive interference where its void.

Clak Doyle : 4:28 Slow motion

David Irwanto : Beautiful

LeiosOS : Man. I am basically researching this in superfluids (numerically). It's super cool (both literally and physically). Let me know if you want to make a video on something like that. I would love to work with you on it!

Darkine Pro : Róóbert Fico si to ty ?

cheeez.plays on Instagram : This reaction is very easy to explain having reviewed the footage very closely.

mirror , : スゲーーーーーーーーーーーーーーーーーーーー! translation:greatー ー ー ー ー ー ー ー ー ー ー ー ー ー ー ー ー ー!

RomaN RaD : Cool!!!

Justin Y. : Man, just imagine how this would look like on a larger scale

Ivanildo Cafu : Nassim Haramein loved it! 😄

DRVO Arquitetura : This got to be one of the most beautiful displays of the cientific process ever made, let alone the motivational speech. The fact that we all got to watch that makes me trust the internet again in this dark times of misinformation.

Mizu Egu : Cool 😍, btw, orang Indonesia mana nih? Bilang hadirr dong :v
