In the unlikely event of the LHC creating a black hole, would we live long enough to know what happened?

I know it's extremely unlikely and perhaps impossible, but let's say the Large Hadron Collider DID create a black hole. How long do you think it would take to spaghettify the entire planet? If I'm on the other side of the globe, would I have time to hear a distant rumbling? Would I have time to say "OH SHI..."? Or would it be more like turning off a light switch?

Even if the micro black hole didn't evaporate (which everyone believes that it would), it still wouldn't destroy the earth. Here's a quote from an article that I found:

If a slow-moving micro-black hole set up home inside Earth and sat there for 13.7 billion years (the age of the Universe), it would weigh in at a puny 10^-18 kg (the mass of a virus).

It would dissolve in a fraction of a second. So I guess it would take infinity time to spaghettify the planet? The point is that it would not.

What would happen if I were to wave my hand through the location of this micro-black hole? Would part of me get stuck there? Would it just pull off some skin cells?

Most likely not. The tiny black hole would go right through your hand virtually without any interaction with the molecules of your hand. The article AnteChronos referred to is good article. Please read it for more information.

Thanks for the answers! Guess I can move on to worrying about gamma ray bursts now.
