Q & A
What is the main product idea discussed in the script?
-The main product idea discussed in the script is a concrete keyboard, which is a unique and unconventional take on a traditional keyboard.
Why is creating a concrete keyboard considered challenging?
-Creating a concrete keyboard is challenging because concrete is not typically used for making thin-walled objects that need to withstand pressure and impacts, such as typing or hitting the keyboard in frustration.
What materials are used to strengthen the concrete in the keyboard?
-To strengthen the concrete, the creators use PVA glue, fiberglass, and additional sand. These materials are intended to improve the concrete's durability and resistance to cracking.
What is the purpose of using a vibrator in the concrete mixing process?
-The vibrator is used to help get the concrete into the small crevices of the molds and to remove air bubbles, which can weaken the concrete structure.
Why is the pressure pot used in the concrete curing process?
-The pressure pot is used to cure the concrete in order to reduce bubbles and increase the concrete's strength, which is crucial for the keyboard's durability.
What role does the vinyl concrete patcher play in the keyboard's construction?
-The vinyl concrete patcher is used as the base concrete mix for the keyboard. It is designed for thin use cases, making it suitable for creating the thin walls of the keycaps.
What is the issue with the concrete keycap stems?
-The issue with the concrete keycap stems is that they need to be strong enough to be pushed onto the keycap without cracking or breaking, which is a challenge due to concrete's tendency to crack under strain.
What is the solution for the keycap stems to overcome the cracking issue?
-The solution is to add a plastic 3D printed stem before adding the concrete to the keycap molds, which provides additional strength and prevents the concrete from cracking.
How do the creators address the molds having different thicknesses?
-The creators address the issue of different mold thicknesses by adding resin to the thinner molds to make them thicker, and then recasting them in silicone to create new molds that will produce stronger keys.
What is the final outcome of the concrete keyboard project?
-The final outcome of the project is a unique and aesthetically pleasing concrete keyboard, with each key having an organic and imperfect look, giving it a stone-like appearance. Despite some challenges and cracks in the space bar keys, the keyboard is functional and admired by the creators.
Outlines
😄 Introducing the Concrete Keyboard Concept
The video starts with a humorous introduction to a fictional product—a concrete keyboard. The hosts joke about the impracticality of such a heavy keyboard and humorously discuss the sales of a product that hasn't been made yet. They then dive into the actual project of creating a concrete keyboard, discussing the challenges of using concrete for thin-walled keycaps that must withstand forceful typing. To address these challenges, they plan to use PVA glue, fiberglass, and additional sand to strengthen the concrete. They begin by mixing a vinyl concrete patcher, which is designed for thin applications, and discuss their unconventional approach of repurposing materials for unexpected uses.
🔨 Crafting and Testing Concrete Keycaps
The hosts proceed with the concrete keyboard project by experimenting with different methods to create durable keycaps. They add a plastic 3D printed stem to the concrete mix to reinforce the keycap stem. Using a vibrator to settle the concrete into molds and remove air bubbles, they engage in playful banter. They also discuss the challenges of getting the concrete into the molds and the importance of removing bubbles for strength. They test various techniques, including adding PVA glue to the concrete mix to increase its strength, and applying fiberglass for reinforcement. After several trials, they find that the control concrete without additives is the easiest to work with, although they note that it may not be as strong as other versions.
🏗️ Building a Concrete Keyboard Case and Addressing Mold Issues
The video continues with the construction of a concrete keyboard case using a mold from a previous resin keyboard project. To prevent cracking, they modify the mold by adding 3D printed plugs for screwing. The process involves carefully handling the concrete to avoid bubbles and ensure a good cast. After demolding, they discover issues with some of the molds, which have thinner tops than expected, leading to concerns about the concrete breaking during demolding. To resolve this, they decide to reinforce the molds with resin to create stronger keycaps. They also create new molds using silicone and Legos for a fun and effective mold-making technique.
🎶 Advertorial Break and Mold Making Mishaps
The video includes a lighthearted advertorial segment promoting Mint Mobile, highlighting its affordability and ease of switching. After the advertisement, the hosts return to their concrete keyboard project, facing a mishap where they forget to add plastic components during mold making, leading to a humorous moment where they must clean out the molds. Despite the setback, they remain positive and continue with the project, demonstrating their perseverance and good humor.
🎵 Harmonica Fun and Custom Mold Success
In a playful interlude, the hosts engage in a brief harmonica performance, adding a touch of whimsy to the video. They then return to the task of checking the success of their custom concrete molds. After a messy process, they are delighted to find that their molds have worked well, despite some concerns about potential breakage. The hosts express relief and satisfaction with their custom mold technique and the resulting concrete keycaps.
🛠️ Final Assembly and the Challenge of the Space Bar
The hosts reach the final stages of assembling their concrete keyboard, expressing emotional investment in the project and admiration for the smooth, organic finish of the concrete keycaps. However, they encounter a significant challenge when the space bar key breaks. Despite attempts to repair it with super glue and adjust the assembly, the space bar remains nonfunctional. They humorously consider a 99% concrete keyboard, with the remaining 1% being resin for the non-concrete components. After much effort and some stress, they manage to assemble the keyboard, embracing its unique aesthetic, including the imperfections and cracks that give it character.
🎉 Triumphant Completion and Reflection
In the final paragraph, the hosts celebrate the completion of their concrete keyboard, admiring its beauty and unique qualities. They reflect on the unexpected difficulty of the project and express their love for the final product, even with its imperfections. The video concludes with the hosts typing on the keyboard and appreciating the cooling effect of the concrete wrist rest, highlighting the functional and aesthetic success of their creation.

Transcripts
Are you tired of keyboards being so lightweight?
(keyboard bangs)
Or do you want to feel like
you're tapping your fingers on the sidewalk?
Well, do we have a product for you.
The concrete keyboard!
(phone rings)
Wait, what do you mean
they haven't even started making them yet?
Again?
I've already sold five thousand.
Tell them to get started.
(dramatic music)
(hands clapping)
(Katelyn laughs)
Oh, oh, oh, you're here. Oh, hi.
Um, Today we're making a concrete keyboard
and we've made several weird keyboards in the past.
We've made it all resin one, we've made an all wood one,
but an all concrete keyboard
introduces some interesting challenges.
Yeah, concrete usually isn't made to make things
with such thin walls that are gonna hold up
to vigorous smashing when you're angry
(computer smashes)
and you're losing your video game.
So we have a few different ways to strengthen it.
We have PVA glue, fiberglass and we have additional sand.
Let's go ahead and start with just a basic concrete mix.
So the concrete mix we're using is a vinyl concrete patcher.
It's already designed for thin use case scenarios.
But is it designed for key caps?
No, not at all.
Like, what we do a lot on this channel is
use existing things for things they were never meant for.
(screams)
Alright, that looks good.
But one thing about concrete, while it is pretty strong,
it's not great at not cracking.
Yes.
Under strain.
And we really worry about
making the stem of the key cap out of concrete
because you really have to shove it onto that key cap.
So what we're gonna do is we're gonna add
a plastic 3D printed stem before we add the concrete.
(light music)
Now how are we gonna get this concrete into here?
With our vibrator, of course.
(Katelyn laughs)
It's seen some use
(both laugh)
with the other concrete in the past.
Yeah.
Do you wanna explain Katelyn?
Yeah, yeah.
Vibration is used to get concrete into the little crevices
and it also helps with removing bubbles.
We're gonna use it for these little tiny molds.
EVAN: Yeah, now watch this. It's not moving.
Oh yeah. Look at that.
(buzzing)
Oh, it's moving.
EVAN: Look at that, simple application of a vibrator.
How do we get it down? With good vibes.
Whoa
KATELYN: Whoa.
EVAN: Whoa, whoa.
KATELYN: It's turning it into soup.
EVAN: Yes.
KATELYN: Oh, see the bubble pop?
And see it like lowering into the mold?
I love how we're minutes into the video
already busting out the vibrator.
I mean.
KATELYN: Oh my gosh, it went down so much.
EVAN: Look at that. That's magic.
I'm realizing that I should probably put down some paper.
KATELYN: Yeah, this is gonna be a messy project.
It was a little bit too juicy.
(beep)
So I just sat down to make more of these
and I have this spare vibrator in my back pocket
and it started vibrating.
I was very surprised.
EVAN: Oh my gosh.
KATELYN: It's one reason
we're working a little bit quickly.
You know, concrete has a cure time
and we wanna get all of our tests into the pressure pot.
Aside from a little control, we're gonna leave out.
We've never put concrete in the pressure pot before,
but that should reduce bubbles.
So we're hoping that the reduction of bubbles
will also make it stronger.
And we need every bit of strength we can get.
Hey, how do you turn it off?
Long hold.
Oh, that was- I put in the pulse mode.
So the guides I read online say
that you should replace
about 10 to 25% of your water
with PVA glue instead
and that adds strength to concrete.
Just like you'd imagine glue would add strength to concrete.
Interesting.
It just makes it stick more.
KATELYN: So we're not measuring.
EVAN: That might have been too much. Who knows?
KATELYN: I thought what you were saying, like,
you should replace 10% of the water.
That meant we were gonna measure.
I did like 50% of the water.
KATELYN: Yeah that seems like a lot of glue.
Okay, okay.
Maybe I'll.
(Katelyn laughs)
You can't talk about percentages
and then not measure.
EVAN: Okay. I'll, I'll add more
concrete so that we can add more water.
KATELYN: Yeah.
It's like we laugh, Teehee, it's vibrators
but like it works so well.
EVAN: This, it works so well.
There's nothing else that would work as well as this.
KATELYN: Like a vibrating table is way too
big for these little guys.
EVAN: Yeah.
Mask up because it's fiberglass time.
I'll actually be precise with this one.
KATELYN: Mkay.
3% by weight.
So this is 20,
3% of that would be 0.6.
I don't know.
You're such a precise boy.
EVAN: We can probably de-mask now.
KATELYN: Okay.
EVAN: Oh yeah. You can already see a difference.
Wow!
KATELYN: Oh yeah, It's um, fibery.
EVAN: Yeah. Look at that.
KATELYN: Okay, I see little hairs.
Whoa. It's so hairy looking.
EVAN: Get in there.
This is not flowing as well.
No.
So maybe fiberglass is better for bigger molds.
Yeah.
Get in there.
KATELYN: I'm not very hopeful about this one.
EVAN: I am not hopeful. It's not flowing.
KATELYN: No.
This is why we experiment.
What if we added more sand though?
(upbeat music)
KATELYN: Is there a ratio?
I'm sure there is.
There you go. What about that?
KATELYN: Sure.
(ding)
EVAN: I think also this might lead
to like a more industrial look for the key caps.
Especially because we might end up having to sand
it some and it might reveal sand.
KATELYN: Sand the sand?
We're gonna sand the concrete. Alrighty.
Let's do it.
KATELYN: Let's do it.
EVAN: Alright, This is flowing nicely.
KATELYN: Yeah, much better.
Yeah, the sand doesn't seem to be prohibiting it.
EVAN: No.
KATELYN: Okay, baby.
Go, go, go.
Pressure pot time.
(countdown dings)
(air compressor revs)
(hands clapping)
Demolding time.
So let's start with the controls.
KATELYN: Yeah.
Now I think that demolding these,
we need to kind of peel them out.
I want to push these in the center
and I want four of my fingers to be on the sides.
KATELYN: Mm.
EVAN: This is my like fifth finger that I don't have.
You have five fingers?
Yeah, but it doesn't work that way.
Okay, ready?
KATELYN: Yeah.
(snap)
Oh. Oof.
Oh no, that was excess anyways.
KATELYN: Okay.
EVAN: Whoa, Okay?
KATELYN: Okay.
EVAN: Okay, Okay. Did I hear a crack in there?
KATELYN: I heard a little crackle.
EVAN: Oh, yep. Oh yeah.
KATELYN: Oh.
EVAN: Yeah. We lost.
It was, it was because that big air bubble right there
that caused a weak point.
KATELYN: Yep. That's what happens
when you don't put it in a pressure pot, I guess.
Close your eyes.
Okay.
Are we doing something different
for the next ones we're gonna demold?
Yeah.
Well we need to, we need to release the
pressure from this pressure pot.
Okay.
Do I need to cover my ears?
No.
(air blows)
(both laughing)
Is there not enough flow? Or is that too too much flow?
I think it's not enough anymore.
Aw. You know, honestly,
that does reduce the volume a lot.
It does.
(air blows LOUDLY)
Ah
Oh my god.
(air squeaks)
Oh, my god.
Oh my god.
What happened?
Right after I said that?
Oh my god. That was terrible.
That was so bad.
I threaded it in here.
That's awesome.
How's your heart?
It's better than ear drums.
EVAN: Woo, wow wee.
Look at the sand.
KATELYN: Whoa. It's very grainy.
I wonder if its.
EVAN: This is the sand.
This is the control in there.
Oh, that glass fiber's looking not good.
KATELYN: Oh yeah. What about the PVA glue,
the PVA glue looks pretty good.
Honestly, the PVA glue is
the one I was most hopeful of.
Hopeful of.
Yeah.
KATELYN: Because it wasn't adding anything with texture
that could prevent it from getting down into the crevices.
(metal clanks)
EVAN: Yeah.
KATELYN: Let's start with the plain concrete.
EVAN: Alright, let's do it.
(instrument strumming)
Yes.
KATELYN: There's a tiny little void.
EVAN: Overall success.
Did that fricking work?
KATELYN: Yeah.
EVAN: Wow, fiberglass surprising.
KATELYN: Now the sand does add
kind of a fun industrial texture to it.
EVAN: It does.
Really good.
KATELYN: Oh yeah.
EVAN: It feels strong. Okay.
Okay. Let's do the sanding test.
Trimming and sanding.
(pliers clipping)
KATELYN: I don't think we necessarily have
to sand down two of each of these.
EVAN: We'll just choose the best one.
KATELYN: Yeah.
(sandpaper scratching)
(rotary tool buzzing)
KATELYN: What is that?
EVAN: It's a rock.
KATELYN: Oh.
EVAN: It's a big rock.
(rotary tool buzzing)
KATELYN: Ah!
It just exposed like a fluff.
(rotary tool buzzing)
I think we can eliminate one right off the bat.
Fiberglass.
KATELYN: Fiberglass. It just wasn't sandable.
EVAN: No, it did like the, the little
Fluff
EVAN: Fibers puffed out.
Sand is interesting because
it has it the most industrial look.
How was it to actually sand it?
It wasn't bad to sand it.
Okay.
Once you got going,
I was able to make my way through it.
KATELYN: What about the control?
EVAN: Control was the easiest to sand,
which in some ways is good, but also concerning.
It also means it's less strong.
EVAN: Yes.
KATELYN: Okay.
EVAN: So I think,
And it looks beautiful.
KATELYN: It is the prettiest PVA glue.
This thing is incredibly hard and dense.
Sanding this, I could like feel the motor straining
be like heated up and stuff.
Oh my god. I think the bigger question is,
what's the perfect balance between strong enough to hold up
for what we want yet not so strong
that it's terrible to sand.
Do we need to do a strength test?
Let's put them on a keyboard and type on them.
Vigorously.
(hands smack)
Alright. First up is the control.
(intense music)
Next up is sand.
(intense music)
(keys clicking)
And now PVA glue.
(intense music)
(keys clicking)
Honestly, I feel like the act of removing them
and putting them on is more wearing on them.
Ooh. Okay. Yeah.
Than typing.
EVAN: Alright. PVA glue.
(key dings)
KATELYN: Throwing it also.
EVAN: Sanded and control.
I mean honestly they all held up pretty well.
To me it seems like the easiest would be do just the
control concrete for the majority of the keys.
Because that's the easiest mix to get consistent.
It looks nice. It's strong enough.
We could always try all of them with the control.
And if one breaks, we make it again with PVA.
Yeah. Yeah.
Yay.
Yeah.
(lips smack)
It ended up not needing any of the research.
I'm glad we did it too so we could learn.
I am too, I am too.
Now can we make a case out of concrete?
So to make the concrete case,
we are gonna use this mold from our all resin keyboard,
but we had to make some modifications to it.
While resin can be screwed into
concrete will crack
if you screw into it.
So instead we added these little 3D printed plugs
that we can screw into instead.
Commence the jigglin'.
I'm gonna start by putting some
of the concrete into these like crevices.
It's so hard to look at.
My eyes don't know what to do.
I almost need to like stare into space.
Ah!
(vibrator shakes)
It jiggled the whole clamp off.
It did
(light music)
(gasps)
EVAN: So much vibrations.
KATELYN: I'm being vibrated.
I'm being vibrated against my will.
I think we have the volume pretty good.
EVAN: I think that's good.
Say hello to my big friend.
His name is Max. Into the chamber!
Open wide mMax, Oh.
(metal clinks)
(air hisses)
Let it all out Max.
(machine squeals)
That's worse than the chicken.
I hate it.
(air noises)
(Music plays )
EVAN: It looks-
KATELYN: There's still some bubbles.
I, which surprises me.
EVAN: Yeah.
KATELYN: I thought all the bubbles would be compressed.
EVAN: Right? That's interesting.
KATELYN: That's weird.
EVAN: Alright, I'm gonna slowly
and carefully work this out.
Release in kind of one edge at a time.
It's worth the time if it's a good cast.
KATELYN: Ooh. Feels like it's releasing pretty well.
EVAN: Yeah.
(tinfoil shakes)
Oh nice.
KATELYN: Oh, still looks a bit wet in there,
but it'll continue curing.
EVAN: Yes. Oh yes
Yes, yes. Look at that.
KATELYN: Whoa. It's so wet.
It's so wet still.
EVAN: I'm excited to see
how this develops as it dries,
but I think that's pretty successful.
And look at the little plastic nubs.
KATELYN: The little plastic nubs. They're embedded.
They're embedded. Very cool.
So you'd think our next step would be making a bunch
of concrete key caps.
(crowd cheers)
And we wish it was that simple.
(crowd awe's)
But unfortunately we have some issues
we're gonna have to address.
We have some issues with the molds.
Most of them are totally good.
They're the same thickness as our test pieces.
We feel pretty confident.
But there are three in particular
that have much thinner tops than the tests we did.
And we're worried that
I'll pick it up later.
And we're worried that the concrete would
break when we demold it.
EVAN: So what we're gonna have to do is
take resin key caps.
We already have, add resin inside of them
to make the top thicker.
Of course we had to add resin to a concrete project
and then recast them again in silicone,
making new molds that'll make stronger keys.
KATELYN: Got enough leveling jigs.
(upbeat music)
EVAN: Oh yeah. Pure resin.
KATELYN: Looking good.
Gonna make you thick.
EVAN: Take a look at that.
I think that's like just
about the same level.
KATELYN: Okay.
EVAN: Well I think that's pretty good, honestly.
KATELYN: Cool.
EVAN: All right, cure.
So I went ahead and made a mold
for our new resin keys out of Legos
'cause it's fun.
Also, doesn't look like a face.
KATELYN: Yeah, I was just noticing that.
It's Gooping time.
You ready to goop?
You know I'm always ready to goop.
Me too. I'm always ready for the goop.
Always ready to welcome the goop into my life.
EVAN: Our lives.
KATELYN: Mm. Thick milk.
Semi congealed ice cream.
Other things.
EVAN: Condensed milk
KATELYN: Glue.
EVAN: Lube.
KATELYN: Industrial lubricant.
EVAN: Industrial bearing grease.
KATELYN: Congealed bacon grease.
♪ Oh, it's beautiful, the goop ♪
It's like a melted gummy bear. Or like a slime.
It is slime.
It is. It is slime.
Goop, goop, goop
Goop, goop, goop.
Yes. Let the goop take over.
Praise goop, praise goop life.
Oh, so luscious.
KATELYN: It's a beautiful chocolate bar.
EVAN: Added a nice thick vein of chocolate
Thick vein.
KATELYN: Mm. Oh, to be buried in goop.
Be like a sensory deprivation tank.
Sounds horrible actually.
That it solidifies around you,
into a thick rubber.
Sounds like a nightmare.
And I designed this to perfectly fit on top of here,
which then perfectly fits inside of Pascal.
So many pressure pot sessions in this video already.
And there's so many more to come.
So many more to come.
Yeah.
KATELYN: Can you believe there's a (indistinct)?
Anything good on?
Eh? Nothing. Great.
What if your wireless bill
doesn't have to be so (beep) high.
Wait, let 'em cook.
Well with our partner Mint Mobile, it doesn't have to be.
But it's too much of a pain to switch.
It takes less than 15 minutes to switch.
Can the commercial people hear me?
No.
You don't even have to change your number.
Which we already know is one (beep).
EVAN: Mint Mobile even provides family plans
that you can easily manage.
I sure miss my family.
I've been trapped in this void for ages.
EVAN: Why should you keep paying more than you have to
for access to the same network?
Mint Mobile is just $15 a month.
Only 15 bucks? Only 15 bucks?
Yep.
Mint Mobile doesn't have stores
or sales salespeople, so they keep prices
as low as they can go.

Thanks for helping us save so much money
mysterious TV people.
No problem.
It gets lonely here in the void.
We're actually looking for friends.
Mint mobile sounds cool, but these two creep me out.
(remote clicks)
(air squeaks)
(horn blows)
How long have you been planning to do that for?
I just saw this on the ground.
I probably shouldn't be putting it in my mouth.
(high-pitch whistle)
Stop it. Stop it.
(horn blows)
That's truly one of the worst noises I've ever heard.
It's the worst.
EVAN: Ooh, it looks good.
KATELYN: Nice.
EVAN: Watch this.
I designed them of removable bottoms.
KATELYN: Ooh.
EVAN: And fully disassemble
into their each individual chunks.
EVAN: Yeah. Legos.
Alright, now I should just be able to push them through.
Yes.
KATELYN: Oh, satisfying?
EVAN: Success.
KATELYN: Ooh.
EVAN: Oh, how crisp and beautiful is that?
KATELYN: That looks nice!
EVAN: I'm really proud
of this mold making technique, honestly.
EVAN: Yeah.
Nice! Two for two.
EVAN: You can feel the Legos
flexing a little bit.
(Katelyn laughs)
Oh yes. Oh yeah!
KATELYN: Oh yeah!
EVAN: Yes.
KATELYN: We did it.
EVAN: That's heckin' beautiful, baby.
KATELYN: They're all clean.
(hands clap)
(game show music)
(countdown dings)
EVAN: Oh, shoot. Oh, shoot.
KATELYN: What?
EVAN: God dang it.
KATELYN: What's happening?
(slams table)
KATELYN: Oh, my god.
We forgot the, the plastic.
And the, the fricking.
(mumbles)
Can we? Yeah. We'll just clean 'em.
We'll just clean 'em out. It's fine.
It's fine. It's fine.
It's fine. It's fine. It's fine.
It's fine.
How many people were screaming at their screens?
Come on, be honest.
Who? Who actually remembered?
Who, who remembered?
Yeah. Who? Amongst ye?
(upbeat music)
KATELYN: Mine died.
EVAN: Oh no.
Can't have your vibrator
die in the middle of it.
I know.
We're in the middle of it.
We haven't even finished.
We haven't even finished.
Can we make do with one?
We'll make do with one.
KATELYN: Okay.
We're not that type of channel.
I swear people,
as I clean my vibrator.
EVAN: Alright, They're all charged up.
KATELYN: Cheers.
(upbeat music)
Okie dokie. In they go.
(metal clanks)
Close your eyes.
NARRATOR: Oh (beep), here we go again.
(harmonica notes)
Oh wow. You're a musical genius.
Oh my gosh.
(harmonica whistles)
Give me a little Jaunty Tune.
No, I ran it out. I ran out. That was fun.
That was, that was the least bad of all of 'em.
(harmonica notes)
Oh and then blow out and blow in.
But do it on the same, in and out on the same one.
(Rick Roll tune)
It's different notes.
Different notes.
Wow.
Wow.
Musical marvel.
And with that, let's check out
how our custom molds did.
I forgot how messy we were.
KATELYN: Oh, we got concrete everywhere.
EVAN: Geez.
KATELYN: We're gonna have a lot of cleanup.
EVAN: Grasp.
Okay. Yes, yes, yes.
KATELYN: Ooh, that looks pretty good.
How's the stem?
EVAN: It's great.
KATELYN: Okay.
EVAN: Success. Nice.
KATELYN: Nice. That is clean.
EVAN: All right, Now this is the one
I am so worried about.
KATELYN: I am quite worried.
A lot more potential for breaking.
EVAN: You're not gonna do that, are you?
No.
KATELYN: No. You would never, you would never betray us.
(struggles)
Ah! Yes!
KATELYN: Woo. We did it.
Our custom molds work, baby.
Ah
Now we just have a bunch of cleanup and more demolding
and more casting and more cleanup
and more demolding and more casting.
(fast music)
We got paranoid about the vibrators dying again
so we bought more.
We are gonna finish this time.
Powerful vibrations.
(fast music)
One of the most satisfying parts of this project.
Hmm?
EVAN: Ha-ha yes.
KATELYN: Concrete chocolate bars.
EVAN: Go for it.
(Evan laughs)
(quick beats)
While we're at it.
We thought we'd also make a concrete
wrist rest because why not?
(music continues)
(air whistles)
(scratching)
So the electronic side
of our keyboard is actually wireless.
There's a battery here,
has Bluetooth but you need
to be able to reach this little
switch to turn it off and on.
So we're gonna have to drill a hole in our concrete, base.
Hope it doesn't shatter.
(drill running)
KATELYN: Don't break. Don't break.
Yay, we have a hole.
You were about to get B-roll
of me putting the electronics into the base, right?
KATELYN: Yeah.
I did a test fit to see if that'll work
it fit in, but I can't get it out!
KATELYN: Well.
I literally don't think I can get this out.
It was too tight of a fit it's not coming out.
KATELYN: Okay.
(slow music)
Guys, after days,
weeks of making individual concrete keys
and other pieces and so much sanding
and so much finishing,
every individual piece is finally done
and ready to be assembled.
EVAN: I'm emotionally invested in the process
and in every single one of these
Concrete feels so nice.
It's so smooth. We got everything so smooth
and just like, can we just have a moment?
Can you just clink them?
(concrete clinks)
They're so nice.
Before we assemble everything,
I have something to admit to you, baby.
I did some little light test assembling a piece just
to see like if something would fit.
Does it, did you break something?
(gasps)
You broke a space bar.
Yeah.
There's a crack running right along there.
Right through this.
You broke a space bar and you weren't filming it.
The ultimate sin.
I, I just super glued it back together again.
And it looks fine.
KATELYN: Yeah. Well, I mean, we have a second one, so.
Yeah, so.
This is why we make spares.
Hopefully we don't break this one.
(buzz humming)
(piano music)
(keys clicking)
KATELYN: Come on.
Oh, come on.
EVAN: Oh no.
KATELYN: You broke the other one.
EVAN: No I didn't.
(somber music)
We're on the home stretch.
It looks, it looks so good, right?
I mean, the break,
the break isn't super noticeable.
EVAN: It's an aesthetic.
KATELYN: Does it work?
EVAN: No. What if I do it one half at a time?
Can't even do that. Okay. Okay.
(strings strumming)
Every other key was nice and cooperative and I love them.
Who needs the space bar key?
KATELYN: See, it's not like it's important.
EVAN: So it's like the position of these can be over here
or over here.
When I'm pushing down.
Can't align it. Align it. Oh, so sweaty.
(blowing air)
I'm gonna try this one. I'm gonna try this one.
The original broken one.
Yeah.
No, I just rebroke it again.
KATELYN: Oh no.
In a new place!
(gasps)
(whines)
I'm gonna glue this one together
'cause this one's completely busted.
KATELYN: Well, they're both completely busted.
What if we just take out those two little side?
Then the space bar will go,
Wah wah wah.
That's fine.
What if I got a hammer?
No.
What if I got a little hammer?
No.
What if we did a 99% concrete keyboard?
What's the one other 1%
Resin.
I'm about to sweat through the shirt.
Good thing it's black.
You're gonna melt the plastic
Just a little bit.
Now I'm gonna open it up just a little bit.
Oh yeah. Say ah,
KATELYN: Open wide.
Oh yeah.
He, he, he. He, he, he.
EVAN: Oh, oh yes. Oh no, did, did it go down?
Come on. Oh, I thought I had it.
Oh! Oh!
KATELYN: Is it?
(hyperventilating)
Yay.
Yay.
Yay
Yay, you did it.
Yay.
Do you need to cool down?
Oh my gosh.
EVAN: It is beautiful.
KATELYN: It's so beautiful.
Like I love, I honestly love
how organic it is
and how each one like isn't perfect.
You know, there's like little discolorations,
like little bubbles and things like that.
It makes it look like stone.
Wait, I just need to like type on it.
Ah!
(keys clicking)
Are you really typing things?
I love you. Kind of.
And other letters.
The wrist rest is very like cooling,
which is nice even though it's like not squishy,
which is what wrist rest typically is.
Like the whole thing looks so cool.
EVAN: It's an aesthetic
KATELYN: And I don't even mind the crack.
I'm glad.
Good job baby. I love it.
This was unexpectedly hard.
I am gonna take a shower now.
(keys clicking)
Just doing a little B-roll.
(laughs)
