Tubes pipes and if was the vacuum

And other about that people show in movies the capsules, os a size of a coke can, travels thru pipes, tubes, till came in the other end, I never knew in any place have that, but if we used the physics? Think the vacuum, the vacuum can smash a can that is heat if you got the air out of a can it collapses, so is a very strong force you know that have bullets that is hit in the space with air, have bullets of gun that is compressed air and is so dangerous than a gun that have a spoleta de polvora in the bottom, I had when I was a child a gun to play that was only spoleta, it have a shot of a gun my father give away from the idea of let me play because the neighbors thought that have some shooting in the neighborhood,  the other of England is air. So if you make the tubes and have the capsules like a bullet have to have a perfect format to travel and the force don't get dissiped inside of the pipes is aerodynamics, bullets and rockets that travel by the initial impulse and travel if nothing dissipates the initial force will travel forever, so think that the tube only travel one side if you want to send is one tube and receive is other, so thinking that you will receive and if you put a pump suction machine of your side and make the tube without air but the direction is in the home of the recipient that the suction is to be make, if have completely vacuum in the pipes the capsule wouldn't be sucked to the other end, and also other case of close pipes is the blood in the veins at it have pressure.

Ps.: And more to create the vacuum, what will make suction, is need to close the tubes, that of course is close the end in the sender, the pipes can't have flaws, the blood in the veins is that, if the person loses a little of the absence of air in the veins, the heart will lose pressure and will pump with less strength.
