For this last one, we reworked the box so the slit was at an angle. We were too tired at this point to figure out what would happen. As it turns out, not very much. On the right, we can see the carpet through the can, which is pretty weird. We were hoping for some twisting, but in retrospect, I think that would require us to change the angle between the vector of the slit's movement and the axis of rotation of the can, and that would take a more complicated setup. Next time!
