#037 Rebroadcast

It's the lesson we've all had to learn the hard way. The pain our mouths feel when we take a treacherous swig of the post-brush poison. This week, Melissa and Jam delve into all of our childhoods to figure out the chemistry of this infamous mixture. Why does it taste so bad? Who's fault is it, the toothpaste or the orange juice? Also while we're at it, why is it called toothpaste? Nevermind, I'm not sure we'll be able to get to the bottom of that part.

#229

In this episode, Melissa and Jam dive into a listener's question about the antimicrobial properties of lanolin found in wool. They explore the composition and characteristics of wool, including its anti-odor capabilities and layers of complex proteins. The duo discusses the challenges of determining whether lanolin remains on wool after processing and its effectiveness in making wool antimicrobial. While the episode reveals that bacteria can grow on wool, it also highlights wool's unique ability to reduce odor and potentially create a microclimate unfavorable for bacteria. Ultimately, the episode showcases the ongoing mysteries and fascinating chemistry behind wool and lanolin.
