Hello and welcome to SciShow Tangents, the lightly competitive science knowledge showcase.

I'm your host Hank Green, and joining this week, as always, is our science expert,

Terry Riley. Hello. And our resident, every man, Sam Schultz. Hello. I'm smiling because I had an idea. Uh-oh.

That's never good for us. So here's the idea. So there's a little bit of a delay when we record

this podcast, just like a click. If we all clapped at the same time, you and to me, you and

Sarah would clap together, but I would clap like a second and a half earlier. I think that right now,

stolen it. It is very nice in here. It's nice little place to get set up and make a podcast.

It's almost like that's what it's for. I did a tour earlier with a student group of the

studio. And this was the room they liked the most. They were like, wow, it really looks

like podcasts happen in there. We're like, yeah, it looks like that. But this is the first

one recorded in there in several years. Yeah. Yeah. Oh, it is nice to be in here though.

And it's nice to see the two of you. So every week here on Tangents, we get together

to try to one up a maze and delight each other with science facts while also trying to stay

on topic. Our panelists, Sarah and Sam are playing for glory and for Hank Bucks, which

I'll be awarding as we play at the end of the episode. One of them will be crowned

the winner. Now, as always, we introduced this week's topic with the traditional science
