Talk:Storm glass

Latest comment: 7 years ago by Weatherlawyer in topic Chemistry of...

Cecil Adams is widely read and respected, but he is by no stretch of the imagination an expert. nor are his experiments scientific. The column in question (http://www.straightdope.com/columns/read/2963/can-storm-glasses-predict-the-weather) suggests a very undisciplined testing method - didn't use a standard storm glass, but built one himself. Storm glasses are probably random and not accurate at all, but to quote Cecil Adams as proof of this is insufficient. I suggest the Cecil Adams reference be deleted. —Preceding unsigned comment added by Cupaxtai (talkcontribs) 04:42, 18 October 2010 (UTC)Reply

I qualified the statement a bit. howcheng {chat} 16:38, 18 October 2010 (UTC)Reply
I agree with the call to remove the section- there is wider literature on the phenomenon which isn't covered and so this gives undue prominence to an unscientific study. Either the section needs fleshing out or deleting. —Preceding unsigned comment added by 87.114.253.8 (talk) 09:21, 16 November 2010 (UTC)Reply

Chemistry of... edit

It occurs to me that there's a healthy bit of chemistry/physics that happens with one of these things...

You start with two different solvents (water/ethanol), with different densities. You throw them into a tall cyllendar and let them sit. They will differentiate to a (probably quite limited) extent. You then saturate the solution with several compounds, and let them precipitate out. The solution is predisposed to not convect much, and later redisolving of the compounds makes the solution at the bottom denser still than the solution at the top, further curtailing convection...

Depending on how well the compounds dissolve in either solvent, I could see them precipitating out near the bottom or near the top, where the two solvents are less mixed, and I've little idea how the mixed solvents actually affects solubility, or for that matter multiple disolved compounds.... Ah, much to think on. 166.147.88.15 (talk) 00:33, 25 April 2013 (UTC)Reply

Agreed the reference to Darwin as his work was not relevant to this article was removed by me and I am asking members of Skywarn Forum to look at making and using three devices each (just so the talk page can have more flesh.)
