If you watch the point where the rocket passes trhu the metal plate closely, with forces on and in slow mode, you will notice that the rockets causes extra shakening and forces variation then it passes, almost like it was colliding to it.
By the way, is it possible to break rubber/metal plates that are size 1 and between 2 anchor points?
And that light speed level is pretty cool
. You cant see anything happen on the metal bar, not even a forces variation.
