What's that smell? Is it us? Is it you? We hope it's neither, thanks to deodorants and antiperspirants. This week, Melissa and Jam delve into the chemistry of this everyday important substance. What are the differences between deodorant and antiperspirant? How do they work in the first place? Does one work better? Is one better for us? Be kind to one another, wear deodorant.

Birds… but chemistry.
What does compost have to do with eggs? How are birds basically doing chemistry experiments to make their colors? Why would a bird eat dirt… or rub ants all over itself?? This episode is a grab bag of wild, fascinating bird facts that connect back to chemistry you already know. No quiz, just vibes.
