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.

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:

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.

Listen in and rethink what’s happening inside that giant magnet.

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.
