Red Carpet Studios91092 14-Inch Cosmix Helix Wind Spinner, Deluxe with Hanger Red & Copper Finish

Q: There is a white plastic rod in the middle. How do I remove that?

The rod is just there to hold the inner spiral in place while shipping. Bend the rod slightly to just slip it out, if I recall correctly I bent the plastic rod enough to put a kink in it. It serves no purpose other than to keep it stable during shipping
