Thanks for the comments. I did edit it, and was wondering when first writing whether I should have said that about oxygen. Incidentally I also tried this with a propane tank, and noticed I could let out any remaining gas by simply putting pressure on the valve with something like a small screw driver, much like with a bicycle tire. I had no issues cutting that one either. It had a different tone--a bit lower. I'm thinking of now finding a bunch of old tanks and possibly tuning them to different pitches by figuring out where to cut them, and creating an instrument with scale notes. I noticed a few empties dumped out by the railroad tracks in my neighborhood. Such waste.
