1. How do you get all of the air out of a plexiglass box?
2. Can a rocket keep on going through space if the fuel was shut off?

1. You cannot get all of the air out of the box, but almost all. It is not possible to achieve a "perfect" vacuum (even in space). You could connect a pump of some sort to a valve on the box, and simply remove as much air as you can. That is the best you can do.

2. If a rocket was going through space, and the engines were turned off, the rocket would keep going through space as long as no other forces act on it (i.e. gravitational pull of objects, asteroids, etc.).
