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

starring some of the geniuses that make the YouTube series SciShow happen this week.

As always, I'm joined by Stefan Chin.

Hello.

What's your tagline?

The back of your leg is always clean.

Boom, take that haters. Sam Schultz is also here. Hello. What's the longest thing you can think of? A blue whale. That's good. Yeah, blue whale's a pretty long. Yeah, I bet they're like, there's some walls that are by the greatines. The Great Wall is big. Human intestines.

They're super long, but not as long as a blue whale, right? How big are they? Blue whales are longer than intestines. What, they aren't, though. They're like 20 feet. Oh, okay. That's pretty short.

You leave the country. You go into the big city. You have big dreams. You have big farts.

And I'm Hank Green. My tagline is darkness is always waiting for you. Oh, come on. True, but depressing. Every week here on SciShow Tangents, we get together to try to one-up a maze and delight each other with science facts. We're playing for glory, but we're also keeping score and awarding sandbox from week to week. We do what we can to stay on topic, but judging by previous conversations, we suck at that!

And so if your tangent is real bad, we can dock you a Hank Buck.

Now, as always, we introduced this week's topic with the traditional science poem this week from me. I wrote this poem about a real-life event that is happening right now in Montana.

In Montana, a rancher once found two dinosaurs

dancing around. A company called and said, quite appalled, those are our minerals in your ground.

Years ago, you see, the rancher had talks. A company paid them to sign several docks. And now the

company cries, when the bones fossilized, they were no longer bones,

they were rocks. So when you own a bunch of land in a place where there might be coal or oil or

natural gas, you sign away your mineral rights, but you keep the surface rights so you can keep
