After a failed attempt to stem the flow of oil into the Gulf of Mexico, BP officials are considering several new approaches to stopping the leak. One option would be trying a smaller container than the 100-ton box previously used to contain the spill and funnel oil to tankers on the surface. Other choices include drilling a hole into the broken pipe to draw the oil into a new pipe, or plugging the well head with a rubbery material. It's estimated that almost 4 million to as many as 21 million gallons of oil have spilled into the Gulf of Mexico. Will the latest containment efforts work? How bad will the environmental impact be?
