Shrink to the size of a microbe and travel the human gut, from the first bite to the grand exit. Fifteen stops, 340 real gut microbes, and a gift shop at the end.
Buckle in. Mission Control drives the Micro-Sub through all 15 stops, with popup science, quizzes and microbes to tap along the way.
Take the controls. Steer through acid, villi forests and the microbe metropolis, and catalogue as many of the 340+ microbes as you can find.
Open the field guide, pick any microbe, spin it under the microscope and feed it. Watch what it makes: butyrate, acetate, vitamins and more.
