Since we are talking about atmospheric gases. Little know fact. Oxygen is paramagnetic. I didn't know this until I went to a class reunion and went to a lecture on low temperature physics.

 

If you have liquid oxygen in a suspended test tube  it is attracted by a magnet and will swing toward the test tube. 

 

Here are a couple of experiments. The first on is the one I saw during my reunion low temperature lecture. On the second experiment it is will suspend itself between two magnetic poles.

Hello.....Fly tying,  fly tyingbiggrin.png

Although the site is fly tying ... the question is about adhesive solvents and health concerns.  The discussion has migrated, but it's still interesting information.  No?

 

I can move the thread to "The Lodge" ... if needed.

I'm not in a big yank about it but my eyes did glaze over a couple of times there.
