Chemistry For Your Life

#236

When a retired chemist wrote in… we had to explore to his great questions. How does reverse osmosis actually work? Should you put aluminum foil in your dishwasher? Why do mixed powders mysteriously un-mix themselves? This episode is full of clever questions, surprising chemistry, and very strong contributions from listener Vince!

Question and Response #76

You asked… so we answered. What do carbon chains have to do with Greek words? How do MRIs make “3D pixels”? Is that pool smell actually chlorine? And wait… are birds blue, or is that just a trick of the light? This episode is a rapid-fire round of your questions, and the chemistry behind them.

#235

You’ve seen it a hundred times… but how does it actually work? Why do diapers change color when they’re wet? What kind of chemistry is happening in there? And how does something as simple as pee trigger such a dramatic color shift? Let’s talk acids, bases, color, and one surprisingly deep piece of everyday science.

#042 Rebroadcast

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.
