How can the same element make both pencil lead and diamonds? This week we wrap up our pencil chemistry mini-series by answering a surprisingly tricky question: how do erasers actually erase? Then we dive into one of chemistry’s coolest ideas. Graphite and diamond are both made entirely of carbon, but one is soft enough to write with and the other is the hardest natural material we know. What chang...

#158 Rebroadcast Gemstones come in all sorts of colors, but how do they get them? Are different stones super different at the molecular level? How do these different colors happen naturally? And how can those colors be replicated in lab-made gemstones? Let's get into it. References from this episode https://www.acs.org/education/students/highschool/chemistryclubs/activities/jewelry-science.html Th...

Why does a pencil work so perfectly? Why does graphite leave marks on paper instead of just crumbling apart? And what do pancakes, honeycombs, geckos, and intermolecular forces have to do with any of it? This week we follow a simple pencil all the way down to carbon atoms, graphene sheets, and the weirdly satisfying chemistry that makes writing possible. Plus: final exam horror stories, missed ala...

What happens when you mix bleach and ammonia? Why does perfume smell amazing on one person and weird on another? And why is getting a job so hard right now? This week we’re answering a huge batch of listener questions about chemistry, sunscreen, scents, books, careers, birds, and somehow even British accents. Plus, we accidentally brainstorm several new podcast ideas along the way. Support this po...

How do you turn a weird cloudy liquid into something stronger than steel? This week we’re telling the story of Kevlar: the chemistry breakthrough that led to bulletproof vests, firefighter gear, reinforced tires, and so much more. Along the way we talk polymers, hydrogen bonding, accidental discoveries, and the chemist who almost went to medical school instead. Support this podcast on Patreon Buy...
