It was right where you said it would be.

There is only one thing left for me to do now.

I'm going to come find you.

[Music]

NOPE!

Nuh-uh! Not touching it!

Nooooo siree bob!

Nooooooo way.

You can mechanically wheeze all you want, Micheal Eggs Benedict Afton, Purple Guy, Jingle Heimer Schmit.

But I am not. I. am. not. spending another 20 minutes trying to piece together whether you're Springtrap,

Whether you're Purple Guy, whether you are a second Purple Guy

And whether all of this requires yet another rewrite of the timeline.

I am NOT doing it!

At least not until the next book comes out in June.

NOPE!

No siree doggo.

Today, the series that prompted lore base theories to flood this channel

is getting the old school Game Theory treatment.

That's right!

Today, I am tackling the science of Five Night's at Freddy's.

Hello, Internet!

Welcome to Game Theory!

Where today's Freddy theory is going to be a bit different.

No source code deep dives, no rooting around for obscure hidden Easter-eggs.

Only hardcore real life research.

Oh, but speaking of the source codes.

Something really fascinating is going on right now.

Scott Cawthon's two websites are having a conversation.

ScottGames is saying things like,

"You're crowding us. You can't tell us what to do anymore. We outnumber you."

And the FNaFWorld is replying with,

"Be quiet. Yes, I can. You will do everything that I tell you to do."

Which makes it seem that FNAF six: Sins Of The Father (It's my title, feel free to use it Scotty C)

Is gonna be like an all out animatronic civil war style battle

against the OG creator William (a.k.a Springtrap) Afton.

How awesome would that be?

Title, gameplay, boom! Done.

Feel free to use that idea as well.

Meanwhile, another FNAF update

Since a lot of you have been asking me on Twitter

about my thoughts on this.

The movie got itself cancelled

and then found itself a new production partner, Blumhouse Productions

the same guy's that did Paranormal Activity, Oculus

The Purge, Get Out. Honestly I think it's great news.

Blumhouse has made a name for themselves

by doing awesome movies on really teeny-tiny budgets

and FNaF as an indie franchise

needs that cheaply made indie vibe to really make it scary.

It doesn't need a big studio like Warner Brothers,

Where it used to be:

going in and meddling and trying to make it more family friendly

so they can go in and sell more FNaF toys

and it becomes the next Minions or something.

Low budget is the way to go

because it forces you to get creative.

So this news actively made me excited for the movie

A video game movie based on FNaF

Seriously, all the subs to Film Theorists

better get themselves ready for a heaping helping of Freddy when that movie rolls around.

Anyway, enough updates.

I think that covers all the FnaF related things that you guys have been asking me about on Twitter.

On to the episode.

THIS WEEK!

I'm covering a topic I've wanted to do since

the release of FNaF 4 back in 2015

and never had the opportunity to

because I was always so busy trying to piece together

the damn lore!

And that is...

Can an animatronic actually kill you?

Since, you know, this series has a lot of animatronics.

And a whole lot of death

at the hands of animatronics

But more specifically, I wanna focus on

The Bite!

*Chomp*

You know the one I'm talking about.

Whether or not you believe this moment to be The Bite of '83,

or The Bite of '87,

Whether or not the date really even matters anymore

One thing is clear:

This is the moment that set in motion everything else in these games.

Based on the evidence coming from six games and The Silver Eyes book,

William Afton, creator of the animatronics, suffers this tragedy

where his son's head gets crushed in a childhood bullying incident.

A few days later, the son dies of his wounds in his hospital bed.

Setting in motion Afton's quest to "put him back together."

Cut to scooping, sister locations, a dead daughter,

and more missing children that you can shake a basket of exotic butters at

and all because of this one moment.

The bite is treated as a freak accident.

Something that couldn't have been helped.

The horrific ending of an innocent childhood prank gone wrong.

A series filled with haunted puppets and reincarnated skin suits starts with this.

Just a random tragic incident that nobody could have stopped.

A simple mechanical failure.

Remember, this is before any of the suits are haunted.

It's still just a regular old animatronic.

But is that really true?

Does a regular old animatronic actually have the ability to crush a child's skull?

Or is there something a bit more sinister going on here?

Let me just say this:

I will never look at my last Sister Location theories the same way again.

And it's all thanks to the results of this episode's research.

To begin to piece together the real danger these Disney rejects pose,

we need to understand what makes them so dangerous in the first place.

Sure, it might be easy to assume that Golden Fredbear

and Golden Bonnie here are so deadly

because they're springlock suits,

but as we hear about in FNaF 3's phone calls,

the locks are only used to hold back the sharp pointy innards

so they could be worn in suit mode.

(voiceover)

It's also something that we witness up close and personal

during night 4 of FNaF: Sister Location.

The springlocks hold back the robotic innards.

And then unsnapping and releasing the mechanism

is what makes them so deadly.

But during FNaF 4's bite,

Golden Freddy is already in 'robot' mode.

There would be no springlocks activated.

They would not be snapping shut.

To put it simply, the robot is operating

like any normal animatronic would be.

Meaning that the danger is coming not from

some weird, unique detail of FNAF-verse style robots,

but rather from the same mechanisms

that exist in any animatronic,

be it in a fictional pizzeria

to the creepy remnants of Big Bear Jamboree heads

looking down on you from the Winnie-the-Pooh ride in Disneyland.

Go ahead, look it up.

There's some nightmare fuel for ya.

Or better yet, if you're at Disneyland,

leaving the Heffalump and Woozle section of the ride,

look behind you and look up.

Oh, prepare for a surprise.

Anyway, all things considered,

to truly unwrap this theory, we need to know

how normal animatronics acually work.

Enter a man named Bernd Reiter,

an engineer who used to build robots for Chuck E. Cheese.

Turns out, how these things are built is actually a closely guarded trade 'secwet',

"Seek-weht," because I can pronounce my 'R's.

But, in an article he did for Nuts and Volts magazine back in 2009,

he confirmed that almost every entertainment robot on the planet is built from one core technology,

pneumatic actuators.

What are those?

Well, yo, listen up then,

ya' homies know when all the sickest ballers wanna pimp out their bangin' rides, yo,

they install hydraulic lifts in their undercarriage --

Like, Ramone, from the Cars movie?

Well, where hydraulics use oil and fluid dynamics to do that sweet lifting, yo,

pneumatics use air pressure.

Ya' build up a bunch of air pressure, and then release it,

That release moves... whatever you want -- a piston, a pulley, the deadly grin of a lifeless singing bear.

They're used in everything, from robots to build cars, to the jaws of... well, Jaws,

at Universal Studios.

Now, Reiter doesn't specify how powerful pneumatic actuators in a Chuck E. Cheese-style robot's mouth would be,

but we can go ahead and calculate a rough estimate.

Where as other actuators in the body and legs would have to be more powerful,

since they're moving larger, heavier chunks of robot, the ones in the mouth are smaller, more delicate.

They only have to move a couple of ounces of plastic and metal for the jaws, teeth, and cheeks.

The pneumatic tubes themselves are also only a couple inches long.

Meaning that they could only build up so much air pressure.

All things considered, you're only gonna need about 40 PSI of air pressure max to do all of that.

That's not a whole lot, it's like the pressure created from a strong breeze.

So how the heck do a handful of small pistons powered by air...

... create enough force to crack a child's skull wide open?

Umm... they can't.

You see, crushing a human skull ain't easy.

The 22 bones of the human skull are there to protect the most important organ in our body from damage,

And the whole thing has got a rounded structure to help disperse any forces applied to it.

The strongest boxer in the world could punch you in the head at full force. and it'd barely crack,

but this perfectly normal Chuck E. Cheese wannabe not only cracks the crying child's head, but breaks through...

... hard enough to cause severe trauma to the brain?

How much force is needed to do that?

Well, it's actually a tricky question.

First, we've got to ask, 'how old is the victim?'

When you're first born, the skull is softer, moldable, since, y'know...

It has to pass through... narrow lady bits.

Once it's made that... journey, it has to be able to accommodate for your growing brain.

So, it has these soft spots called fontanels to give the skull flexibility.

So I immediately thought that our crying child birthday boy

might be a bit easier of a nut to crack

considering how young he is,

but the research didn't pan out that way.

The soft spots dissapear, or ossify,

by the time that you're 9-18 months old.

And I don't care how heartless of a killer you are, purple guy,

you ain't letting your one year old

hobble his way home after a day of sitting terrified in a broom closet.

Second, to answer the question I had to ask,

"What parts of the skull are we talking about?"

Because different sections have different thicknesses, and as a result, different strengths.

According to research done by Tobias Matei

who studied children's bike helmets and how they protect the skull,

the thinnest region of the skull bone is about where your temples are.

Lo and behold, that's exactly where our Crying Child is seeing most of the damage done.

When he's placed in Golden Fredbear's mouth by the bullies, he's facing outward towards us.

Mostly facing the camera, meaning that the weaker sides of his skull are the ones that are having to deal with the crushing forces of the teeth.

So, I looked it up.

To fracture the skull there would require the equivalent

of a 1,100 pound man

or 500 kilogram woman

(Equal opportunity, not being sexist here.)

to step on the head in that exact spot.

But then again, that's just to have the thing fracture.

We're talking about a catastrophic head failure that impacts the brain.

We have to get more specific and a bit harder of a bite.

Luckily, I found a study looking into exactly that.

Testing over 300 samples, some scientific madmen

determined that human skull bone, when put under various kinds of stress,

had a failure pressure of 1900 PSI or 13 MegaPascals.

13 MegaPascals means that for every square meter of surface area,

it takes 13 million newtons of force to break a skull open.

Now obviously that number is hard to imagine without giving you a real world example of what it feels like.

The challenge, though, is that to accurately represent that pressure we need to know how that pressure is being delivered.

If I'm delivering a lot of pressure onto a small point,

it's going to do a lot more damage than if I deliver that same amount of pressure across a wider surface area.
