avoid yet another accident. the first few times, i skidded through the cones, but with practice brakes. reporter: the third time was the charm. a better feel for snow and ice and having passed the class maybe a break on my car insurance. let s reiterate one point here. if you have antilock brakes and most cars over the last 10, 15 ye years, come with them. you apply steady pressure. the brake may bounce back at you. that s okay. steady pressure that allows the tire and the brake to grip. if you don t have antilock brakes, that s when you apply the pumping pressure. most cars, norah, have antilock brakes. steady pressure. it will bounce back at you. that s okay. steady pressure. back to you. good information, thanks so much. up next, president obama not shying away from the tough
pumping pressure, too, and that should have the mud pushing the oil back down through the well pipe, but officials are taking it very slow, very cautious approach and they say even they don t know when the process will be complete. although they say it could involve up to 70 hours of pumping. anderson? how do they know they ve reached the goal? how do they know it s been stopped? reporter: yeah. that s a good question. it s in that word static, anderson. they re taking periodic readings and in case in this case when we use the word static is not moving. static means not moving. right now, i want to show you this little demonstration here. the oil is pushing up very hard inside that well pipe, about 7,000 pounds per square inch. they re adding the mud with pressure on the top, because without the pressure there s so little mud initially, it would blow it right back up if you didn t have that pressure pushing back on it. but the mud is heavier than the oil. as they ntinue to push i
that green light at the static kill and so far, anderson, no signs of anything going wrong with it either. i should point out, tom, once again, we are reading tea leaves and waiting for press releases from bp because they have continued to refuse even though they once said they would do it to have some real-time explanation of what s going on in the live picture. correct? reporter: exactly. we get periodic updates through press releases or a brief phone conference. that s about it. so we don t know we won t know for a while this ship is, what, pumping a lot of barrels of heavy drilling fluid. do we know what s going on? reporter: yes. that s what we know. we won t know if it s working for some time. it s pumping many barrels of heavy drilling fluid or mud, as they call it, down into the oil well about a mile under the water. they re steadily increasing the pumping pressure, too, and that should have the mud pushing the oil back down through the well pipe, but officials
