How about this solution for the oil spill?

I’d like your help in putting together this idea…

You know those long bits of steel like one finger width and a lot of meters long, that they use in building construction? I don’t know what that’s called. It’s what gets the concrete on top.

I’m imagining stuff like that being inserted in the spilling hole, but possibly upgraded with hooks to grab inside the hole.

Then more and more of those metal strips would be inserted. Somehow the increasing pressure would have to be accounted for.

And what about a bunch of pipes meant to simultaneously propelling a sealant inside the hole?

Is this train of thought with any practical merit in your opinion merit? Please let me know.
