I understand that fiberglass is made by blowing high pressure air on extruded “blobs” of glass. Is it safe to say the same is done with steel wool (using an inert gas)? Or is it created by the steel wool fairies?
Do not ever call the big strong men that “blow” steel wool “fairies”. They hate that stereotype. 
Sorry, it was just too easy to resist.
Sumultaneous identical threads are a no-no around here…one of these’ll have to be shut down by a mod. My vote goes to this one.
