89 - Glowing Things

Published: Aug. 4, 2020, noon

Glowing Things: is that a scientific topic? Yes, but not by much. In fact, we spend a lot of the episode figuring out of there even is a scientific definition of 'glow!' Very exciting!

Here's a little fun fact for all you Sam-heads out there: my favorite color is 'glow-in-the-dark green." That's right, I finally admit that I'm the one writing all these descriptions! I guess Ceri doesn't do everything after all, huh?! 

Peace,

Sam

There is a LOT about this submarine, and a lot of it is contradictory! A very fun Google rabbit hole to fall down.
