- The drops that form around the side of a wine glass are strange, but most people don't realize just how strange. Here the effect is explained, along with time-lapse footage of these "tears" or "legs" of wine to show the effect for what it truly is.
Naturally, such a short video has to contain some simplifications. For more details, check out the Wikipedia article (en.wikipedia.org/wiki/Tears_o...) or James Thomson's original explanation in 1855 (books.google.com/books?id=MVIw....

Great video. I watched it to the very end.
'Cause it's blood of grapes.
I had never noticed that the legs could run up, as well as down. It might be time to see this for myself by pouring a few glasses of wine, you know, FOR SCIENCE!
Phenomenal. I love this.
So cool! I drink wine every day at home (Argentine wine is really good and cheap so why not?). This is very interesting, I'm going to take a closer look at my glass tonight
Great video and explanation. The animations explained the theory very well. Also love the music. Thank you!
Outstanding! Wine trainers and educators will savor this one. The explanations and analogies are clear and precise. Thank you for the terrific time-lapse footage!
I observed this one of these days in a glass of whisky. I was fun to just keep watching those drops form and fall. I immediately remembered this video, and came back to watch it again.
Glad to hear it was worth a re-watch. I've seen these in whisky also and have always wondered if the dynamics are any different.
Great, thorough, easy to comprehend explanation and excellent videography. Well done!
Finally, tears explained, simply and clearly! Good job
Great filming and explanation, thank you
Very good explanation! The comparison between the people on the escalator and the wine was perfect!
Great video! I'd never noticed this before and found your explanation to be easy to understand and fascinating! Thanks!
Best thing I saw all week on youtube. Thanks for sharing!
good clip man, keep up the good work.
Dude, great video. I forwarded to a High School teacher looking to inspire her students. She is thrilled. Keep doing what you feel passion to do!

That's fascinating. Well presented too, and with beautiful timelapses.
Except for the fact that this was very interesting, the video was really nice and I love how it almost sound like you speaking through a phone, I was surprised of how soothing it sounds.
Very good, the best explanation I've seen, thank you!
I love a simple yet awesome explanation!
Very interesting, cool, and aesthetically pleasing. The visual effects of the time lapse photography made me think of geese drinking water from a pond. Nice execution!
Great job that was one of clearest explanations I have ever heard for legs in wine, please do one explaining tannins
informative, yet beautiful video! and the music!
Dan, you rock. I cannot wait to share my newfound knowledge on my wine tours. Thank you.
Thanks Christina Ernst - enjoy the wine tours, and thanks for spreading the word.
the best explanation that I have seen about the issue.
Very interesting, and your explanation made a lot of sense.
It makes me watch over and over again. (great music too) Thanks for sharing.
Well done! That was very clear and concise.
Well done. A terrific science explanation for the average wine consumer. Very entertaining and informative. Bravo!
Great video, didn't even know wine did that. And you explained it really well.
Also, Emancipator is a great artist, hearing that was a surprise. Song is "Wolf Drawn", for those wondering.
Thanks Dan! Possibly the only clear and simple demonstration of the Gibbs Marangoni on the internet...Cheers!
This video was amazing, will you make more?
This was fascinating and most entertaining! Thanks for enlightening us about the legs of wine.
Great use of time lapse, gorgeously shot with a lovely subject matter (if we say so ourselves)!
Nice vid. Great atmosphere.
Your voice sounds like its coming from outer space (through mission control). Adds to the atmosphere.
great explanation!
I love it!
Best explanation I have found for this!
This is so well explained! well done!!!
Great explanation :) thank you!
Great info, great music, very interesting. Thank you.
Beautiful video, thank you for making it
Good explanation. Enjoyed the wine dance!
Fascinating! I loved this video and h hope you make more like it.
This is a fantastic explanation. I was a Physics teacher for many years and sometimes used this example when discussing surface tension. I just wish I had been able to explain it as well as you. Thanks for this great post.
Thanks Tony Suffolk - that means a lot coming from a veteran teacher. Glad to hear other people are using this great example.
This was a slay.
Thank you, great video!
This video is the perfect combination of science and art! Well done!
@Dan Quinn or whoever made this video: this is superbly good, you must keep making educational TH-cam videos for the sake of humanity.
Thanks! I didn't know that. Was very informative and entertaining :)
Excellent video, thank you
Great explanation
Fascinating! What a cool video.
Brilliant video!
Great video!
Very interesting. I've wondered about this before and figured it had something to do with the interactions of water and alcohol, but I wasn't sure how it all fit together. Great video.
cool video, explained really well.
cool vid.. made even better with the emancipator track in the background..
A cogent and fantastic explanation of what is perceived as a mysterious event. Well done. Natalie Berkowitz
very cool! and informative
This video is extremely well thought out and executed.
Good choice of music.
Great video, thank you!
the elevator-wall analogy was just great!
Awesome vid!
I've always been told that you could get a reasonable idea of the alcoholic content of a wine by observing how quickly the tears move: now I know why!
Nice piece. I once had a supposed wine expert solemnly inform me that the legs were simply glycerine, and I demurred a bit and suggested that at least there was some interaction with the alcohol.
Great video. Explains it well. Could do without the music though much louder than the narration.
Good choice of music too :D
This channel needs to come back.
Thanks for the great explanation!
Any idea why in a glass of milk there is a narrow clear band between the film left on the walls of the glass and the milk left on the bottom?
This Video was so relaxing to watch
I'm pretty sure the author of the video got drunk at least once during the making of this wonderful video :P Thanks for the information :) (I'll definitely see this in a future James Bond movie)
Really good!
Awesome video!
Keep the neurons spinning because that was mind blowing!
This video is amazing.
Very nice!!!
This is amazing :D
nice video kudos man
AWESOME!!!! THANK YOU!
Nice vid and explanation. But you should have also mentioned that it is most seen in wines with a higher alcohol content. The disparity in evaporation rates and surface tension means it will be seen more readily.
Beautiful. Where does the energy for the water to move the pepper come from? I understand the concept of surface tension but energy has to come from somewhere. Would it be heat-based and thus the water cools when you add detergent?
Sometimes gradients can provide the potential energy to initiate motion. Think of salt fingers - the gradient in salinity provides the potential energy that is converted into the motion of the water. I suspect the energy balance of the Marangoni effect can be explained in a similar way.
"So the obvious question is, 'What the hell is going on here?'"
Brilliant. I little humour can go a long way in teaching.
Legs of wine explained brilliantly
so nice!!
that pepper thing was crazy!!!
Beautiful
VERY COOL VIDEO!
Damn. This is beautiful
This was great! I use it in teaching about wine all the time. Now lets do one that defines what thicker, more frequent VS thinner less frequent might indicate and tell you about a wine before you taste it. :)
Agreed! Doing that study and making another video is on my bucket list
Why does it look like the drops falling stops just short of hitting the surface?
I love Emancipator.
really cool!
Before this video I never knew wine had legs or tears, now I can say I've learned something new today.
as a drop fall and it gets thinner, does surface tension work to pull the drop back up the cup? It appears like some drops fall but are pulled up like a yo-yo before they reach the main body of wine.
Also, is this a spontaneous effect? that is, do you have to swirl the wine glass for this to happen, or if you just left a glass of wine untouched, would the tears of wine occur eventually?
I cry if I spill the wine. The wine doesn't cry if I take a spill.....somehow that seems unfair....;) Thanks, Dan.
Could you use this principle to create what looks like constantly flowing rain on a small fake window? It might be a neat little decoration or experiment to create.
That might depend on the angling on the inside of the window, might be hard to find non-parallel glass sheets...
When I was at Fort Campbell I used to o to the Beachhaven Winery a lot - they explained these "legs " had something to do with the sugar content and were different for whites and reds. Sounds like time to do some tasty research!
Does that mean that eventually vine is gonna become just water?
Don't think the alcohol along the vertical edge would evaporate faster than on the horizontal surface (unless there was a temp difference), but the relative percentage would change faster in the local environment due to restricted diffusion from less underlying volume. Otherwise great explanation, thanks!
The ending was so awesome O.o
this is so cool.
What is the song at the end called?
emancipator ♥
nice display!
Awesome vid. But not all wines get these tears. Why do some (often cheap) wines not have these legs?
