Crews in the Gulf of Mexico are trying to find a way to stop an oil leak from turning into a geyser.
As many as 40,000 barrels a day have been pouring into the water since last week's drilling accident.
Robot submarines have been brought in to try and plug it. Meanwhile, airplanes are spraying chemicals over the water to break up the oil.
The spill is about 70 miles from the coast of Louisiana.
