SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

episode 37: Glowing Things
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.
