If you were wrong that it's not coil spring but rope, then here's my answer:

The colored ribbon didn't transport from its initial/original position to the end of the rope.


(Actually it depends on your observation, that's what I've observed during our class, we have done the same activity)


But if it's really a coil spring:
The colored ribbon, still didn't transport from it's initial/original position to the end of the rope because it seems impossible.

My answer maybe right IF the colored ribbon wasn't tight.
