Abstract: A fluid dispenser and a mold used for manufacturing the fluid dispenser are disclosed. A baffle inside the fluid dispenser extends from an area on the bottom of the fluid dispenser toward a first side wall and away from a second opposite side wall forming an acute angle with the bottom. A gap between the baffle and the first side wall allows fluids to move freely from one side of the baffle to the other permitting emptying most of the residual fluid through a dip tube disposed into the bottom corner with the second side wall. The mold contains two cavities each disposed within a block configured to close over a molten plastic parison. Each cavity comprises a blade configured in a way that closing the mold produces the baffle inside the container.

Abstract: The module, following the geometry of joined truncated icosahedra, is designed to provide, when a plurality of them are joined to form a space vehicle, at least a subsistence environment for terrestrial life, including a centrifugally induced artificial gravitational field, as well as an in-orbit base from which larger space structures can be built.

Abstract: The genus extender is a toy block designed to be used with a plurality of homohedral modules, either by itself or with other genus extenders, in constructing geometric models with a topological genus of two or more.
