Everything they have tried has failed thus far,hence its still liaekngThey first tried to close the blowout preventer,when the rig was burningNow that everything is piled up,on the sea bed i believe its made matters worseThey then tried to cut the riser pipe,not sure if that workedThen they built a box to capture the oil,but it blocked with iceThey tried top kill pumping stuff in to block it,ive herd mention of golf balls and tyresDont know if to believe that or notNow i believe they are drilling what they call relief wells,in other words more holes that could also leak
