Summary
What if your underwear could track your toots?!
In this hilarious and science-packed episode for kids and families, Mindy, Guy Raz, and the gang head to FLATUS FEST to discover a real invention from the University of Maryland: smart underwear that measures human flatulence (aka farts)!
Along the way, we explore:
- Why we fart (yep, it’s science!)
- How gut microbes create gas
- What “normal” farting actually looks like
- And how scientists are building a real-life Human Flatus Atlas
Plus: a toot-tastic festival, musical mayhem, and one VERY gassy Gramma G-Force.
It’s the Who, When, Wow, How, and WOW in the World of Smart Underpants and the Science of Toots!
