Product Description
PolarityGear is the name for a Patent Pending toilet paper and paper towel holder. It uses high-tech magnetic discs with "detents" to provide a stepping torque resistance. An "undulating helix" is used to adjust the distance between the disc and hence, the amount of resistance.
This toy demonstrates the how the adjustment of the undulating helix affects the magnets and torque resistance.
