Wasn't this one already featured more than a year ago? 75.18.210.253 08:29, 25 February 2007 (UTC)

There was a different image of a ferrofluid magnet yeah, just about a year ago. It's the third image down on ferrofluid. What I want to know is what the greyish layer between the fluid and the glass is. 210.229.27.76 09:03, 25 February 2007 (UTC)

No, the other ferrofluid pictures are featured on Commons. This one is the first featured ferrofluid image on English Wikipedia. howcheng {chat} 05:04, 26 February 2007 (UTC)

So the black stuff on top is actually a liquid? That's crazy! --Soakologist 21:38, 25 February 2007 (UTC)

What's with the cool haircut? Why is the liquid all spiky? Is it normal mag field behaviour? 68.144.80.168 (talk) 06:39, 4 August 2008 (UTC)
