After 911, when the pentagon was taking suggestions for exotic weapons, I sent them a proposal for great stuff bombs to use with the Afghan caves. That would be a really nasty way to get sealed into a cave. That stuff finds every crack and crevasse.
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.
I believe you are referring to Super Elastic Bubble Plastic. Man, that was great stuff. I wish I had hoarded it!
At 10,000 psi, it would take a lot more than a cardiologist with a strong grip to inflate anything.
