Water drop on DWR-treated fabric
Voting period ends on 13 Jul 2011 at 20:45:20 (UTC)
 * Reason:Cool physical phenomenon. Put into several articles.  We lacked any good picture of beading on DWR until this image was created (was an awful pic from afar of a gray jacket, but you could not see beading).  Plus pretty-looking with the blue fabric and the shiny water.
 * Articles in which this image appears:Contact angle, Durable water repellent, Fluorosurfactant, Fluorine, Wetting
 * FP category for this image:Featured pictures/Sciences/Materials science

 * Comment: Could use some cropping; there a lot of fabric in the image and that's not what we're interested in. I'd say making it a square would be about right.--RDBury (talk) 23:13, 4 July 2011 (UTC)
 * Good point, on both, was wondering that. Could you do it?  I trust your eye. Please?  (On the square, they are nice for looking at as isolated pics, but as an article writer, I have a bias to short y axis becuase of the interaction with sections on text wrapping.TCO (talk) 23:45, 4 July 2011 (UTC), although in article I really care about, it is out of the text wrapping, so square could work fine...TCO (talk) 23:47, 4 July 2011 (UTC)
 * I cropped it.--Mbz1 (talk) 00:33, 5 July 2011 (UTC)
 * Like it cropped and square. Have put that version in all articles now.TCO (talk) 02:05, 5 July 2011 (UTC)

 * Weak Oppose - I'm not sure I see the EV of this shot... maybe better for Commons?  ceran  thor 01:08, 5 July 2011 (UTC)
 * It's a fundamental physical phenomonon caused by the fluorines at the end of the fluorosurfactant molecule. Read the article on contact angle and on fluorosurfactant for the physics and chemistry.  We had not a single picture of this (despite how seemingly simple it looks.) It's a $billion+ industry btw and has environmental controversy.TCO (talk) 01:16, 5 July 2011 (UTC)
 * I understand. Not everything can be a featured picture though. I'll change my vote to neutral, though I may decide to support.  ceran  thor 01:49, 5 July 2011 (UTC)


 * Question I'm not up with my lingo, but the caption reads "near spherical", but it doesn't look remotely near "near spherical". Wouldn't "near oblate" or something like that be a little more suitable? – Kerαu noςco pia ◁ gala xies 04:59, 5 July 2011 (UTC)
 * Agreed. Simplified caption.TCO (talk) 05:06, 5 July 2011 (UTC)


 * Weak support Great EV, is a very clear illustration of a non-wetting surface (that linked article could use a practical picture like this as well). My only concern is the saturated starbursts of light from the sun, but I suppose it's unavoidable due to the reflective nature of the fabric and the need for an intense direct light to show the shadow illustrating the extreme curvature of the drop. - Running On Brains (talk) 17:35, 8 July 2011 (UTC)
 * Added pic to that article. First glance is that article might be merged with contact angle (and is kind of a mess layout wise).  I can't fix the whole 'pedia though.  :(TCO (talk) 17:46, 8 July 2011 (UTC)


 * Weak oppose Definitely a candidate for valued picture, but it is a reasonably common phenomenon, and with a better camera a much better photo could be taken. Aaadddaaammm (talk) 08:22, 10 July 2011 (UTC)
 * I agree. The amazing thing is we had nothing in Commons! (posted by TCO Aaadddaaammm (talk) 10:10, 10 July 2011 (UTC))


 * Oppose I'd like to see the surface perpendicular or very nearly so to the lens. Then we could see the contact angle and so on better. Surface_tension might interest some looking to see a (mathematical) description of the shape. JJ Harrison (talk) 08:21, 14 July 2011 (UTC)
