 * Reason:(nominating on behalf of Synapticrelay who has been inactive for several months) The animation meets all the criteria of a featured picture and Synapticrelay deserves our formal gratitude for creating such an outstanding illustration of the concept. It has a max resolution, as an animated image, of 1,400 × 1,080, but it was dialed back to 600 × 463 for size considerations. But animated images are allowed to be smaller. It is otherwise clear and focused and has no display issues. In my opinion, it is certainly among Wikipedia's best work. I simply cannot think of a better illustration of viscosity and it immediately explains the concept to lay-readers. It is verifiable by common knowledge or any physics or engineering textbook mentioning the topic. The caption could probably be expanded, but the quality of the animation is such that very little needs to be said about it. No digital manipulation. Again, thank you, Synapticrelay, for creating and uploading this amazing picture. Footlessmouse (talk) 00:58, 17 November 2020 (UTC)

 * Support. Instantly gets the concept across without need for annotation. We don't have enough featured pictures that are scientific illustrations rather than photos or historical reproductions, and I think this is a great example of its type. —David Eppstein (talk) 22:37, 17 November 2020 (UTC)
 * Support per above. --Janke | Talk 06:29, 17 November 2020 (UTC)
 * Larger version is very pixelated, but the smaller one looks good. Support, although I'd like to know what the method for making this was. Computer simulation of viscosity? If the user was more active, I'd like to hear a lot more from them. Adam Cuerden (talk)Has about 7.7% of all FPs 04:53, 18 November 2020 (UTC)
 * Hello! I am the original creator of this image. I created this in Blender 2.79 using the built-in fluid simulation mechanics, and rendered in Cycles. I have the original files available, and would be able to create a higher-resolution/clearer image if need be. Thank you so much for the nomination! Synapticrelay (talk) 02:19, 19 November 2020 (UTC)
 * I think it's good as-is, since the higher resolution would also cause issues with rendering gifs. maybe a high-resolution video for those that prefer that? But that confirms the physics, so that's good. Adam Cuerden (talk)Has about 7.7% of all FPs 11:00, 19 November 2020 (UTC)

 * Support The boundary of the orange fluid where it meets the floor jitters a lot. Can this be easily fixed? cm&#610;&#671;ee&#9094;&#964;a&#671;&#954; 02:25, 20 November 2020 (UTC)
 * Comment I believe it is inaccurate. The flow is less for the viscous flow. Charlesjsharp (talk) 20:21, 22 November 2020 (UTC)
 * Hi! I believe you may have misunderstood the caption: the fluid with the higher viscosity, the orange fluid on the right, flows slower than the other. Viscosity is a continuum: the viscosity of water is (in terms of dynamic viscosity at NTP) on order of 10-3 Pa*s while the viscosity of corn syrup is on order of 100 Pa*s. (Going out further, the viscosity of most glasses are of order 1018+ Pa*s) So the animation is basically just an illustration of the difference in fluid flow for two liquids with viscosities differing by about four orders of magnitude. We can reword the caption if you believe it is confusing. Please let me know if you have any questions or if I have misinterpreted your comment. I hope this helps.

 * Fine if you specify the relative viscosity Charlesjsharp (talk) 12:02, 23 November 2020 (UTC) (CEng FIMechE)
