#042 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 fly all the time. We see it constantly. But how does it actually work? Is it just "Bernoulli’s" principle? Is the air pushing up? Are the wings pushing down? And what’s happening at the molecular level when a bird takes off? Let’s talk about feathers, airflow, collisions between air molecules, and why the way flight is usually explained might not actually be the whole story.

A kid’s question sparks the episode. 01:00 — “Isn’t this physics?” Why a chemistry podcast is talking about aerodynamics. 02:00 — A disclaimer about flight explanations Melissa explains why common explanations of bird flight can be misleading. 04:00 — The weird analogy that starts it all What does oobleck (cornstarch and water) have to do with bird wings? 06:00 — Air isn’t nothing Thinking about air as billions of tiny molecules interacting with wings. 09:00 — The classic explanation of lift Bernoulli’s principle and why it’s often used to explain flight. 13:00 — Why that explanation isn’t the whole story What’s missing from the “air moves faster over the top” idea. 18:00 — Collisions at the molecular level What air molecules are actually doing when a wing moves through them. 22:00 — Pushing air downward Why deflecting air matters for creating lift. 26:00 — Wing shape and angle How airfoil shape and angle of attack change the behavior of airflow. 30:00 — Flapping vs gliding Why bird flight isn’t the same as airplane flight. 34:00 — Turbulence and airflow patterns What’s happening behind the wing as the bird moves through the air. 37:00 — Bringing chemistry into the picture How thinking about molecular motion helps make sense of the physics. 39:00 — Final recap So… what actually keeps birds in the air?

In this bonus episode, we host a rematch of our game “Fun Fact or Fake Factoid” with Claire and Jam, using stricter rules: each claim must be entirely true or false as worded, and the winner earns a treat. We test statements about pregnancy-related brain changes, koala fingerprints, bird body temperature, whether every fig contains a dead wasp, how egg markings form, woodpecker tongues wrapping around their skulls, unique parrot pigments, bald eagles’ ability to take off from the ground, black bear maternal instinct, and whether red bird color is structural rather than pigment-based.

MRIs are loud. They’re huge. They’re magnetic. But what are they actually doing? This week, we bring Claire back to help us connect the dots between NMR (yes, organic chem flashbacks) and MRI. How does a technique built on tiny hydrogen protons turn into a 3D image of your brain? How can it tell the difference between tissue and fluid? Why can’t you bring metal anywhere near the machine? We ask: • What are your protons doing inside an MRI? • How does “magnetic resonance” become an image? • Why does oxygenated blood matter? • And how did anyone figure this out in the first place? If you’ve ever had an MRI, or just wondered how we can see inside the body without radiation or surgery, this episode pulls back the curtain.
