Amazing. I had roughly the same idea, with used condoms.

No really, I hope she’ll be listened to ASAP, and it’ll work.

It’s more similar to a gigantic tampon actually.

She needs to stick with teaching, not doing. There are just a few 'minor' details to deal with:
1) Tires don't hold air until they're on a wheel.
2) Wheels rust.
3) How do you get them in the well, past the partially sealed BOP with 10,000 psi oil gushing the other way?
4)How do you get the air in them, once they're in place (the local friendly BP service station doesn't fill tires)?
5) What's the coefficient of friction between the pipe and the tire?
6) in a three foot diameter pipe with 10,000 psi oil in it, the up force is about 10 million pounds (pi r squared p). What air pressure in the tire is required to resist this?

Like I said, she should stick with her class room.

Does anybody remember the rainbow-colored goo from the 70’s that was marketed as a toy? Put a wad of the stuff on the end of a rigid straw and blow through it, and you’d get a rainbow-colored plastic “bubble” you could play with. The stuff didn’t inflate easily or evenly but it was fun. I’ve often wondered if they could use a similar technique on the pipe...similar to an angioplasty but leave the “balloon” in.
