for years.

A see-through suppressor with a high speed camera

COME ON!

This is awesome!

The problem is I didn't

have access to licenses or the equipment necessary to make it.

All that changed when I met Steve.

Hey it's me Dustin, welcome back to Smarter Every Day.

I'm with Steve and Steve makes suppressors, right?

That right.

What's the name of the company?

Soteria

Soteria

Suppressors

(Here to fire off suppression)

Okay this is something we've been wantin' to do

FOREVER

This is a Good old Boy Alabama deal i've contacted steve he's contacted me he likes the high-speed camera i like the concept

Of See-through Suppressors so we worked out a Little Deal Here when you Say all right so what are we gonna do

We're gonna fire our suppressors with

Using a cast Acrylic as a Casing we Can Actually See What transpires

Inside the suppressor once you know the Round leaves the barrel and

The Compressed gases behind It you know come on a barrel Create pressure wave in the ignition of The gases?

We get to see what Actually

As the bullet comes Out from the end as It Expands

So you Got this this Expansion coming Over Here towards Your microphone right right so what i i wouldn't Expect This pressure field to be

Symmetric or even Spherical it'S gonna be it's gonna be like a Lobe Correct a

reverse mushroom and You can See that if we Take The Muzzle brake off of It and you can Actually See

When the When the Round Exits the barrel Within on course you can See that reverse mushroom Cloud oh?

That's awesome The moment we've Been Waiting for

There we Go this is ptfc seal

Steve Would like to say something

I can Say full disclosure here we've never fired the 308 with a cast acrylic suppressor before

I think it's gonna break i do

so

But My guess is if It Does Fail That we're gonna get a Failure right Here near the thread on the back?

or the front and That's because of the

Stress Concentration What Kind of Thread did You use is a Sharp-toothed Thread This truncated Thread It'S a fine Thread

Hopefully It won't but if It if It does we're gonna Get some Great High speed Hints the Lexan

There we Go

I think it broke Where i thought it Would

Yeah My engineering professor Didn't lie to me

Have You ever Seen that? I've never seen that

I've never seen anybody do that before

I've never seen ANYBODY do that before!

Munford People What's Mumford People Mumford usa Mumford Alabama Mumford Us i don't understand the reference

We'd be recnecks.

But we Design and Stuff The fact that It came off had to do with Axial stress like iF once It pressurized That Tube

It's pulling the Whole

Can And Those Threads Just Couldn't Handle That Right Right

Okay so the one we're about to do is something you Actually sell That's right and you've Never Seen It like This? Never have

Cool so this is a .223 and the idea here is to?

Contain The Gasses in the back and Then Stop It from exiting with that Diamond Pattern in the front

so if you think about What the suppressor is doing there's two Stages to it the first one is the

Capture of The gases on the inside of is Expansion volume and Then There's This Restriction to flow

To keep Those Gases Inside the can so you don't let them flow out

There's This Really Cool Thing That happens when you Spend a Lot of time Designing Things

Eventually You start to see things and you Just Kind of have a Gut Feel like engineering Judgment on this next suppressor

Steve had that Gut Feel right before we Pulled the trigger he can Hear him yell out it's pretty fun

he didn't want to shoot This i

Convinced Him to do it Because It Was the prettiest one in my Mind i thought i could see more of the gases what steve?

Didn't tell me is that This Was one of the first conceptual designs Sotiria made back before They'd done much Research

He also didn't tell me that he had no Intentions of Shooting This one so he made it out of Thinner

Acrylic As a Display Piece it's got like This claw Built into it and that Claw Kind of Looks like it's going to

Grab Some of That gas and not Let It Go so I'm Pretty pumped about that You Ready

Ready to fire!

Why didn't you tell me! I did it i said full disclosure and you went on with the test anyway

I said it was my favorite

Because This ones Got claws it's my favorite design and you Knew it was gonna

How did you know it was gonna fail in all seriousness?

Well It Was a Smaller Diameter

On that .308 It Works Well on the .223 but on the .308 we Need more capacity

That's a 30

That's 35 millimeter

Suppressor It Needs to be like 41 millimeter

This Is a Developmental test so let's see what we can Learn

Instead of Using a segmented Baffle System This Type of suppressor Uses a Monocore Design so it can Be Easily Cleaned in the field

We fired Another Round Through The monocle Without containment so we could see exactly

What was happening as you can See these flat parts are flexing Out from the inside and They're pushing on the inside of the sleeve

Causing a Localized stress Concentration This is Called destructive testing and it's my favorite Part of engineering

Steve obviously Knew this was going to break if we Used a metal can and this Wouldn't

Have Shattered But What he did is he weakened one part of The system so that We Could See how strong the other

Components were won't you figure that out you can figure out

How to tweak your design and you can make a Really strong

Overall Product Without Making It Too Bulky This is Really Smart and it's something That engineers do all The time and it's one of My

favorite Things in engineering ok That Was everything i thought It Would Be It was Rad i've Got a super cool

Sponsor to introduce to you today This is not a normal ad This is a

Really Big Deal For The Sandlin Household We Have Been hoping that hellofresh Would sponsor smarter Every day for a Really long Time

I'll Let my Wife who talked about This on the podcast i'll let her Explain How our?

relationship With hellofresh Started Would You like to Explain How this came about i

Basically Bought Myself a

Subscription for Christmas so i wouldn't have to do as Much meal planning or shopping for the new year and other People have?

Asked to support Smarter Every day are these Milk refining Type Things

Yes and other meal planning companies Have sent us Meals and i did not?

Like The Setup or the Food options and so i went back to paying for hello fresh because i enjoyed it Better

We Really Wanted hello fresh
