Oil is back to gushing from broken pipe at the bottom of the Gulf of Mexico as BP removed a leaky containment cap to replace it with a new, better cap (they swear). If the new cap, named "Top Hat Number 10," works it could capture nearly all of the oil spilling from the leak. But like any of these attempts, it's not as easy as it looks. Coast Guard spokesman Capt. James McPherson said, "It's not just going to be, you put the cap on, it's done. It's not like putting a cap on a tube of toothpaste." It's more like Tetris.

Things do seem to be going smoothly so far, if you discount the oil now spewing into the water at thousands of gallons more per day. Robotic submarines removed the cap yesterday, and BP aims to have the new Top Hat on by Monday. Still, the cap is just a temporary fix as permanent relief wells would not be finished until mid-August at the earliest. According to CNN's numbers, 3,713,200 gallons of oil have spilled into the gulf since the April 20th explosion. Check out the video below of robots removing the cap:

Experts warn that Top Hat Number 10 could actually work too well, and the results could be even more catastrophic for the gulf. Professor Paul Bommer said that if the 150,000 pound cap "does work and they shut the well in, it is possible that part of the well could rupture if the pressure inside builds to an unacceptable value." If the pressure builds too much, it could blow the cap off. But it's nothing a good "junk shot" won't fix, right?
