The Karpinski Genii Tube has unique features that differentiate it from the traditional Genii Tube. The square design, rather than the more common cylinder design, has two distinct load chambers which can be filled separately. Additionally, the hinged division allows the tube to be opened vertically and shown empty. The angled wooden slats that create the load chambers have been painted black to blend with the sides and to disguise the change in depth.
