What keeps our lungs working like a well-oiled machine? In this engaging episode, Auto tries to “upgrade” the way humans breathe using balloons, only to end up popping them all over the place! Luckily, Nakira calls in expert scientist Dr. Maddy Sauleda from Dow to explain the real magic inside our lungs. Dr. Sauleda introduces kids to surfactant, a special substance that lowers surface tension and lets the tiny air sacs in our lungs (alveoli) expand and contract easily. Without surfactant, breathing would be a lot harder! Through laughter and hands-on curiosity, kids will explore how their bodies use hidden scientific principles every day, making even something as simple as breathing a fascinating discovery.
