Kids love to read about gross things like pee. But few realize how fascinating, and even educational, the subject can be. You can learn about all sorts of things from pee—American history (Civil War belles hoarded urine for making gunpowder); the animal kingdom (when lobsters fight they squirt each other with pee from bladders on either side of their eyes); even espionage (scientists are using urine to classify "odortypes" that will identify individuals as accurately as their fingerprints).

In this sequel to the wildly popular The Truth About Poop, Susan E. Goodman and cartoonist Elwood H. Smith bring their humorous touch to a book that’s overflowing with compelling, if stomach-churning, information.
