Oil from the wrecked rig off the coast of Louisiana has been leaking at an estimated 42,000 gallons a day, a large amount that could lead to problems if not stopped.
Experts say right now, the oil does not pose a huge threat to the environment, as long as it stays off-shore.
The oil undergoes a process called weathering out in the open, that makes it less toxic to marine life.
However, if the oil continues to spill into the Gulf of Mexico at this rate, things could get messy.
Since the rig was only 50 miles out, experts say there's a chance the spill could reach the coast.
