[light static]
>> All right, man, we're starting fires.
Because we're talented, and very scout-like.
>> JASON: And--
>> BRIAN: That's a good, that's, uh, the mush mound method.
I love it. So, we've already verified, yes, it's true,
the sun can cause fires.
>> Quite quickly.
>> You're welcome, science.
>> Yes.
>> Uh, we, we got that figured out.
>> Yeah.
>> So, now let's talk about this. Uh, ferrocerium rods?
>> Ferrocerium rods. Often mistakenly called
flint and steel.
>> Right, because they're neither flint nor steel.
>> Yeah, in fact, we made that mistake, because this
is the same material that's in a lighter.
And we made the mistake of calling it the flint,
when we did - >> Oh!
>> - the little flash-bang episode.
>> Got it. Yeah.
>> --is extract the flint. >>--and the flint.
>> Get the flint. >> --and the flint.
And flint, this is just rock.
Pushing the flint up, and the flint--
>> The flint--
>> Hold the flint away from you.
>> That flint is spring-loaded.
I broke so many of the flints.
>> People got a little fired up about that, so to speak.
Do you think if we heated this up, it would do the same
thing with the exploding, only just big huge?
[laughs ominously]
Okay, that's a future episode.
>> I think we need to find out. But, uh, yeah.
It produces extra-hot sparks...
>> Op, yep, there it is.
>> -that are, like, what, over 3000 degrees Celsius?
>> Yeah, dude, 5500 degrees Fahrenheit, almost.
Have one of these, you're able to produce sparks for,
pretty much ever and ever. You're doing great. No.
>> I'm just knocking the--
>> Just knock it all, like, crazy.
So, all it has to do
is be struck on something hard. >> Yeah.
And you can use like a knife or something like that with this,
but we've got these little devices here.
>> There you go, we'll use the utili-key.
[clatter and scraping]
Okay. What, uh, what is your game plan here?
>> I'm just throwing the sparks at the burn-y stuff.
>> Oh! Look at that.
>> See, okay, so this is using the serrated edge
of this, right? >> Yep, yep.
[Jason's vocalized affirmation]
>> BRIAN: So the, the problem is, I don't think... well, hold on.
[scraping]
What is it we expect to have happen?
>> Uh, that--
>> Are the leaves, let's put the tinder on.
Let's pretend we've got a yak.
>> That's much better. Yeah.
>> We put [stammers]
>> We found and slaughtered a yak, here, on the property.
They're running wild out here, by the way.
>> Build the rest of the teepee.
You know, [stammers] no, no, a teepee,
what are you doing? You don't build a teepee out of yak hair.
>> You keep s--
>> The yak hair is the warm gooey center
of the teepee.
[through laughter] >> The warm gooey center.
>> Yak teepees is my favorite candy.
>> I clearly don't know anything about fires.
>> There you go, keep going. Yeah! There you go. You got it.
Here's another fun fact, kids.
Outdoors, these are called twigs.
You'll find them everywhere. [laughs]
>> Also, this place is just filthy with yaks. You got to do
something about that, dude.
>> I love the fact that everything we're grabbing,
like, the thought of getting out of the chairs
does not even occur to us. [laughs]
>> Oh, I know. It's just, what can I get. [grunts]
[laughter]
What is the laziest possible way we can do this episode?
>> We're surrounded by fuel.
I feel like we're getting near
a respectable teepee.
>> It's just turning into an art project now.
>> It's, why, are you kidding me?
I'm going to get an A+ on this.
>> Is that yak hair? Are they just super-flammable creatures?
[laughter]
>> I would love to believe... that someone is like,
god was just, like, "Not going to lie.
I made a mistake on that one." [laughter]
>> Man... >> "That's on me, bro."
>> Man, in certain parts of Asia, you just see yaks,
running on fire, in the burning plains.
>> Okay, I'm going to guess that it's going to
just leap right in there and go, instantly.
>> All right. Well I'm going to...
>> Nope. Nope.
Eh. Eh!
You're supposed to get in close.
I see that in the--
[stammering] see, okay then you do that, right?
>> That's... yeah.
>> Come on, baby. Come on. Yeah!
>> Yeah!
>> BRIAN: Yak hair! >> JASON: Okay. Okay.
>> Take that, yaks! Why are you still attacking?
>> Because, it's going out! >> Attack the yak, no, it's fine.
Here we go, here we go, there we go.
All right, so now,
now you want to put, you want to put more of the, the little
uh, twigs and needles on there. There you go.
♪ ♪
Yeah, no, it's still going.
Look, we got it. >> Oh, is it?
>> We already won. We defeated the mini-boss.
[bewildered stammer]
It's like, I said the words, "We defeated the mini-boss,"
and you're like, "Let me fix that!"
>> I'm just, "No! More fire, Brian!"
>> No, you have to wait until...
>> Oh.
[laughter]
Oh, that's how it works.
>> All right. >> That's how fire works.
>> That's one more, uh, legend tested.
[drum hits with every word on-screen] >> Legend tested. >> Ferrocerium rods actually work.
>> Maybe we wouldn't die in the wilderness.
[laughs] >> Yeah.
>> I mean, we probably would. >> Don't get ahead of yourself.
[in relief] >> Ah.

[notably quieter] It's great.
>> I want to name each of these
as a click-baity question. Like, uh, "does the sun light fires?"
Yes, yes it does. "Do ferrocerium rods work?" Yes.
Yes they do.
[laughter]
"Will a MAPP gas torch light a campfire?"
[laughter] Yes, yes it will.
