What to do with a tank that has failed hydro?

Make some wind chimes! I took this in Big Sur, CA in 2006

RJP,

The exploding tank is on U-Tube already if you want to see it.
YouTube - Tank Shootout

Yeah, I know. (It's an "inside" joke, sorta. There's been a great many, legendary "I would like to see a scuba tank explode" threads here on SB.)

I have an old tank that I've been wanting to screw around with. I thought it would be cool as a bell, but don't know where to start. What's the most practical way to cut into this thing? Plasma torch?

I had a buddy at the machine shop cut my cylinder. It is perfect, he did it at no charge...

Can that failed tank be turned into a torpedo? Hahaha...just joking....

cut the bottom off, remove the valve, hang it from the valve opening, hit it with a metal object. and it becomes a great bell that can be heard from quite a distance.
