About This Episode

Welcome to History's Not Boring! Mira and Finn are diving into a super gross topic today: BACTERIA! Yuck! Did you know that before a certain amazing discovery, even a tiny scrape or cut could turn into a huge disaster? Doctors had almost zero way to fight off those invisible, nasty germ invaders. People got really, really sick, and there was nothing anyone could do! It was scary!

But then, one day, a brilliant scientist named Alexander Fleming made a totally messy mistake and left something fuzzy and green on his lab desk! Oops! Instead of throwing the moldy thing out, he looked closer and realized that this disgusting green stuff was actually a superhero! It was killing the bad germs!

This messy, accidental discovery led to the first antibiotic—the ultimate germ-fighting medicine we call penicillin! Tune in to find out how this glorious, gooey error changed the world forever and saved countless lives! It’s the coolest, grossest history lesson ever!
