What is the digestive system?

Did you know your mouth makes enough spit in your lifetime to fill a whole backyard swimming pool?! Eww! Get ready for a messy, mind-blowing adventure as Mira and Finn shrink down to take a roller coaster ride inside the human body! We are following a single bite of a crunchy red apple as it travels all the way through your incredible digestive system. You will discover how powerful squeezing muscles let you swallow food even if you are hanging upside down on the monkey bars like a bat! Then, plunge into a churning stomach acid bath that is strong enough to dissolve metal razor blades (don't worry, your tummy has a special slime shield to keep you safe!). You will also explore a shark-sized tube folded up in your belly, meet millions of microscopic fingers grabbing your nutrients, and say hello to the thirty-nine trillion friendly bacteria living in your gut right now! Plus, we are answering the ultimate question: what exactly is poop made of, and why do we have to go? Buckle up, because science has never been this gross, or this awesome!
