Bahcall sees Paper Showers as a natural extension of the nation’s “green” trend: as more people walk or bike to work, more people will need a fast, convenient cleaning solution. With more than one hundred thousand sold since 2011, it’s hard to argue his point. Reviews for the product tout its uniqueness -- although actually using it takes some getting used to -- and functionality. Thanks to his Paper Shower idea, Jim Bahcall is really going to clean up.
