What would you make with this?

I have 2 out of date medical O2 tanks sitting here.

If you're offering to sell or give them to me to cut up and use as a crucible, I do appreciate it, but it would cost me $10 to drive there and back and I don't get up that way very often. I'd rather just buy one for $20 that I don't have to cut, etc., have it delivered to my door and use it right out of the box. Maybe some other flat-lander can use them though.
