"Everybody farts! Even Queen Elizabeth and Justin Bieber. You probably know farts best from yourself, your family, and your friends. But how does a fart become a fart?"

This is exactly what mother/daughter duo, Stine and Hannah Dreyer set out to examine and they have developed their own Fartotology, the teaching of farts and how they develop.

Some farts are noisy, some a completely silent - and all research shows that loud farts smell less whereas silent farts smell of death and destruction. You choose freely between pest or cholera: do you want to hold the fart back and risk that it develops into a "Silent Stinker"? Or do you prefer to release the "Firecracker"?

Something all farts have in common is that they are funny, even if they appear at the worst possible moments: in class, in the middle of a good game, during dinner.

This book invites curious children and their parents to talk about shared experiences with different fart types, including the "Bubbler", the "Firecracker", the "Horror Honk" and the "Serial Fart".
