Farts. Trouser trumpets. Sulfur squeaks. Or toots, as Lulu insists on calling them. Smelly bubbles of air we don’t like to talk about. But Songbud Alan and Producerbud Ana are not ones to shy away from the stinky sidelines of science. 

First, they take us to a concert hall to meet a FARTchestra and hear how behind some of the world’s greatest works of art lies the power of farts. Next Dr. Juan Pablo Zhenlio takes us through the ecosystem of human digestion, meeting trillions of microscopic organisms to learn why we fart. Then we jump into the world of animal farts. What do snake farts sound like? Manatees? Cows? Chimpanzees? Birds? 

Finally we ask the most important question of all: What would happen to the planet if we stopped farting? 

For more on toots, read Dani Rabiotti and Nick Caruso’s book Does it Fart? The Definitive Field Guide to Animal Flatulence.

Special thanks to the Brown University Orchestra, Dr. Juan Pablo Zhenlio, Dani Rabaiotti and Nick Caruso.
