Bill Nye on the "top kill" method

Aside from the fact it's a terrible tragedy and a total disaster, the undersea oil spill is a fascinating problem. Here's a video from CNN with Bill Nye "The Science Guy" on how "top kill" works. It's more than just sticking mud in a hole! Incidentally, he was the speaker at my PhD graduation and I was proud to shake his hand. I mean Bill Nye, not John King.
