    Product Description


    1.  Using the paper towel, charge both ends of a combination acrylic-PVC rod and place it on the swivel (the thin set works well on the overhead).
    2.  Again with the paper towel charge the acrylic rod. Bring it near the acrylic end of the mounted rod– it repels.  Bring it near the PVC end & it attracts.
    3.  Repeat with the PVC rod and any of the other rods you wish to try.
