Cat, no I do not take pictures and I am glad I do not. Sky & Telescope, and sometimes spaceweather.com and other sites, report periodic problems doing astrophotography now because of satellites passing by and leaving lines and streaks across the image.Rod, do you do any astrophotography? I should think that, with exposures of any length, you would get more satellite contamination? Surely this would be a real distraction, creating unwanted lines on photos. I suppose you could take them out with Photoshop or similar, but this would be an added nuisance?

Have you ever put a fire to a fine grade steel wool pad? They burn, we as kids knew this. Try it , you will see.I have found this, which might help:
When used as a fuel in commercial products and industrial processes, metals usually come in the form of a powder. Although, even if you have ground a metal block down to a powder, it still won't burn as efficiently as it could if you just use the oxygen in the ambient air.18 Feb 2018
Why don't metals burn?

Perhaps, but they sure would light up. I thought about it being an additive also. If you got them wet they would rust up.Clovis,
No, I have not tried that. But there is a difference between applying a flame to a finely divided substance, and something heating up by friction. Also, I don't know what there is in a wool pad - maybe some organic soap type detergent?
