New cap placed over Gulf oil spill - will it work? (photos)

Workers prepare to lower a new cap that will hopefully stop or at least slow down oil leaking from the Deepwater Horizon oil drilling platform in the Gulf of Mexico. As of 7:00 AM PT on Tuesday, the cap has been placed over the spill and workers are attempting to put it into place. BP is currently testing the plug and says it will know in two days how successful it will be.

Although there were some reports that the leak had stopped, live images on Tuesday morning showed they were premature.

Here's a shot of the cap as it is in place.
