I'm a sucker for Luc Besson. Any movie with M. Besson as writer/producer/director, I'd watch them! Even more if it was Luc Besson's and Jean Reno played in it! Woohoo...!
Now, please try to imagine this scene: A car with all its window rolled up, skirted off the bridge and fell down to the body of water down below. It gradually sank, taking its driver and passanger trapped inside to the murky bottom. Suddenly, while being fully submerged in the water, the driver's side window burst open and the driver heroically pulled the passenger and both escaped to the surface. Then they swam to the shore and thus were saved from death.
I'm sure you were all familiar with that kind of scene, at least with some variations.
The latest version is what I saw in Transporter 3. Frank Martin, the Transporter, got out from his car by kicking the passenger's window into pieces.
Unbelievable power!
You see, because I like science, whenever possible I'd watch Discovery Channel, or NatGeo, or some other channel that aired science programs. Now, in one of the Mythbuster's episode, the host tested the best method to break a car's glass window and whether it was possible to escape like what people can see in so many movies.
First they used a manual window fully submerged in a shallow tank. The muscular man tried to lower the glass using the window lever. No matter how hard he tried to, the window just wouldn't roll down. The lever even broke in his hand.
Then they sank a car door with electrical window. The man once again pressed the window switch to lower down the glass. Interestingly, you could hear the motor whining but the glass just wouldn't move.
The next method they used was using a steel hammer to smash the glass. That person swung the hammer again and again furiously but the glass didn't even crack. He kicked on the glass but nothing happened.
Then they decided to try the special glass-breaking hammer, the one you can see in buses as an emergency tool. The hammer is small, the handle is to be held in one hand. The head is a bit larger than a permanent marker but with a pointy tip. To their and my wonder, the glass cracked with the first impact. With another blow the glass shattered thus the trapped victim could escape.
The explanation for this is what we called hydrostatic pressure.
The hydrostatic pressure acting on the plane (all of the surface of the car) made it impossible for the smaller force exerted on the glass to pull the the window down. I should describe this in a picture you know but let me describe it in a comical way.
Imagine it like when someone triple your size stepped on your toes and you just can't pull your leg free -- because you don't have that much power (lesser foce). Now, the only way for you to do is to politely ask the big guy to move his foot. But then again, maybe he will. Or maybe he won't. In that case, possesing various persuasion skill surely come in handy.
But -- back to the window again -- you can use the special hammer with the pointy tip that made the area of the surface so small that the same force you use (whacking at the glass) create a much greater pressure on the surface (its P = F/a where P equals pressure; F equals force; a equals area on which the force is applied).
Simple physics. I believe you must have got it in the 8th grade.
Now, that made Frank Martin's escape is improbable because no way his legs have that much force!
Therefore, he should have just drown to death in his car. Just like that bad guy said to the exotic Ukrainian woman.
Did I mention that that Natalya know ways to arouse even a dead man?
