Bill describes the Alignment Optical Telescope used in the Lunar Module on the Apollo missions to the moon. This telescope took star sightings which were used to align the Module's guidance system. Bill shows how the telescope used an Archimedes spiral inscribed on its eyepiece to replace the heavy motors, worm gears, and rigid tracks used in a traditional sextant -- this shaved weight from the Lunar Module and allowed it to carry more fuel.

Bill reveals the stunning engineering underlying the design of a diaper. He describes the five layers of a diaper, including the superabsorbent polymer in the diaper's core. He illustrates the action of this polymer with a stunning demonstration using a single bead of polymer: it soaks up enough water to grow from a diameter of 4 mm to nearly a half inch.
