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

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

Sarah E. Riley. Sarah, did you know that a cup of coffee has as much caffeine as four

cocoa colas? No, I did not know that, but that feels like quite a bit of caffeine.

Yeah, which tracks for me, because sometimes people will be like, well, I use so you can't

drink coffee. You drink coax all the time. It's a quarter of four coax at once. Yeah.

Who drinks four coax? Anyway, I'm trying to stop drinking coax because there's just

it's a ridiculous amount of pure table sugar to be putting into my body. But the problem

with that is that I need the equivalent amount of caffeine, which is difficult to get other

places. That's just a me problem. How are you doing, Sarah? Oh, I'm doing okay. I think

I've thought more about caffeine in the past one minute than I have in the past year.

I don't use caffeine in any way. I just I'm tired all the time.

Yeah. I would love to see caffeinated, Sarah. That seems like going to be a trip. I got

this unsweetened tea at the store. And that's twice as much caffeine as in a coke. So I've

have drunk half of it. And I'm going to try my very hardest, just pure mental strength

to not have the rest of it, or also joined by Sam Schultz. Hello, Sam, our resident

every man. Hello, here on SciShow Tangents, we get together. We try to one up, amaze

and delight each other with science facts. And we try to stay on topic while we're doing

it. But sometimes I'll just rant about caffeine instead. Our panelists are playing for

glory and for Hank Bucks, which we will be awarding as we play. And at the end of each episode,

one of them will be crowned the winner. Now, as always, we introduced this week's topic

with the traditional science poem this week from Sam.
