"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.

Baby shower idea: "The shower guests are each given a few diapers and some Sharpies and are asked to write a message to the new mom on the front and/or back of the diapers. These diapers are to be reserved for late night changings by mom (or dad – let's be fair!) so the point is to write something funny or encouraging to give her a little pick-me-up in the wee hours of the night!"

There are hedgehog diapers now? Adorable.
