How The Massive Dome Will Cap The Oil Spill (VIDEO)

In a first of its kind operation, BP will attempt to cap the gushing oil well in the Gulf with a 10-ton concrete-and-steel dome more than a mile underwater. If it works as planned, and no one is certain it will, the procedure would stop most of the hundreds of thousands of gallons of oil pouring into the Gulf.

CNN has a handy video showing you how this is supposed to work.
