I am Lincoln and this is Dan.

- We had so much fun last time with our friend, Shonduras,

that we want wanted to bring him back

for another crazy video.

- I had a blast as well, I did the behind the scenes,

and in the comments, you guys left some weird ideas

of things we should cut open next,

so we're gonna take your--

(blast)

- (spits) What the...

(spits) We're gonna cut up a fire extinguisher.

- Yeah (spits).

- And before we cut this thing open,

we gotta have a little fun with it first.

- Let's do this!

(upbeat music)

(Lincoln shouts excitedly)

(Shaun laughs) (Dan shouts excitedly)

- [Shaun] Blast off!

(Dan shouts excitedly)

- I didn't know fire extinguishers could be so awesome.

Dan's got the tools now. - [Dan] I got 'em.

- [Shaun] We need to got this thing opened, yeah? - [Dan] Let's go cut 'em open.

- [Shaun] What the--- (Dan grunts)

- [Dan] Oh!

- [Shaun] I got, I got--

- This one right here is your basic, it's called ABC.

A means your trash, which is like wood and paper,

B is your gas or oils,

and then C is something that has a current to it,

like you plug it into the wall.

And so this is your most popular because it covers

the three of the most common types of fires.

- These ones are what I like to call the kiddos.

They're smaller versions of this one.

- And then this one is pretty much just pressurized water.

It shoots off, it's really cool, but we--

(Shaun and Dan laugh)

That's why he went under the table. - [Dan] That was good.

- It only handles A fires,

so for anything that's chemical, electrical,

this guy isn't gonna be the extinguisher

that you guys want to use.

- The last thing we want to do is just cut into this thing

'cause it's, apparently it's going to explode all over us

because it's filled with nitrogen that makes it - [Shaun] Apparently...

- [Dan] so it would go out. (Lincoln laughs)

We're gonna knock it a little bit

on the side with a rubber mallet.

If we do it gently enough, then possibly,

all the nitrogen's gonna come out,

and then we can cut into it and it won't be as dangerous

and we can see what's inside of there.

- 'Cause there is still,

- [Lincoln] Powder. - [Shaun] There's still powder in here,

we didn't use it all, so...

(knocking with rubber mallet)

- [Dan] Whoa...

- [Shaun] Oh now it's gonna come. - [Dan] I hear a noise.

(air escaping)

- [Shaun] Can you hear that?

- [Dan] Then we get to the end and it just explodes

all over us.

(loud click)

- [Shaun] Whoa!

I'm not gonna lie, that scared me. - [Dan] Right, I was gonna say that (laughs).

- [Shaun] Alright.

- [Dan] Okay, we got this guy.

- It's like a giant pixy stick.

(Lincoln shouts excitedly) (Shaun laughs)

(upbeat music)

- [Dan] Check this out.

It is full of that powder with--

Oh, there goes my grass.

- [Shaun] Well.. (Dan and Lincoln laugh)

- When we were at the fire extinguisher store buying this,

there actually is a store that sells fire extinguishers. (all laugh)

They told us that this powder is 98% baking soda.

So that's all it is, and once

they put the nitrogen inside of it, and put the pressure,

that's really what makes it shoot out.

So when you take a look at this

when I dump it into this bin...

- [Lincoln] Oh no...

- [Dan] It's just that powder. - [Shaun] It's just a powder.

- [Dan] That's it. - [Shaun] It's crazy.

Actually, didn't they say if you mix it with water,

it turns into concrete or cement?

- [Dan] Oh! - [Lincoln] Oh yeah!

- We should do that.

(water spewing) (Shaun laughs, speaks inaudibly)

- [Shaun] That's enough I think.

Let's mix this and see what happens.

- [Dan] Making your brew.

- So here's the inside of that fire extinguisher.

Here's the top that we cut off.

This video was so much fun to make.

In fact, you've got to go watch the behind the scenes

on Shonduras' channel, because it was so funny,

some of the outtakes that we have on there.

- And we'll see if this turns into cement,

because supposedly, this is slowly turning into cement.

It was crazy, we actually went to a fire extinguisher store,

talked to a professional fire extinguisher salesmen,

and bought all these fire extinguishers, learned about them,

that's all in the behind the scenes as well,

along with bloopers, mess ups,

so I hope you guys enjoyed the behind the scenes

on my channel, and yes, I will announce the winner

of the skateboard as well.

- And if you like us collaborating with Shonduras,

and you want to see him in more videos - [Shaun] More!

(Shaun laughs) - [Dan] Let us know.

- Thanks for watching and subscribing to What's Inside.

- And look, now you guys are on the behind the scenes.
