Bill the Engineer Guy shows how the humble diaper is actually a feat of engineering combining various layers and materials in order to produce a remarkable liquid soaking device that's entirely disposable.

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.
