Hi
I would love to see what Hipyo Tech would think of these keycaps. This was a great project!
Yay this video is awesome
thanks for always making me smile! whenever im feeling down i watch your videos and they cheer me up! keep up your good work!!! lots of love from a long time viewer ❤
You should try concrete acid staining next, it looks like it makes some really pretty results.
After the wood and the cobblestone keyboard I'm waiting for the copper and iron and gold and diamond keyboard 😂
Honestly, a metal one would be so cool
you never know, it could happen haha
And netherite
Stained glass keyboard?! 😮
Built with in water keyboard??????????
The comedic timing of “it reduces the noise a lot” followed by the most ear piercing scream was just absolutely perfect lol
I KNOW RIGHT??? I LITERALLY LOST IT IN FITS OF LAUGHTER, IT WAS GLORIOUS
Aaaaaahh I’m being vibrated against my will 😂is most crazy sentence I ever heard 😂
Mmmmm. Thick milk 😂
Love this video
Primo coffee snortage for me 🤣
In the most benevolent way possible, Evan has the most muppet-like energy I've seen in a human person
this is one of the funniest things ive ever read but so soo true lol
@@underworldrat it's delightful and so fun to watch
AM I A MAAAAN OR AM I A MUPPET! (Am I a muppet!). If I'm a man, im a muppet of a man!
Evan and katelyn put more effort into their sponsers than many creators put into their whole videos, and it makes the adds genuinely fun to watch.
I still skip them out of habit lol
That's probably one of the reasons they get so many sponsorships. Their ads don't feel like ads, they're actually incorporated into the videos, they make entertaining bits. It makes people actually WATCH the ads
Makes you actually want to watch them
@@lijau5418 Give them a shot!
"I am being vibrated against my will" is a crazy sentence without context
NoT tHaT tYpE oF cHaNnEl
Creative people are often kinky
Even with context XD
Don't kink shame
Cnc vibes
"We got nervous about the vibrators dying so we bought more" "we are going to finish this time"
...Giggity.
Slowly but surely becoming that type of channel
Embrace the chaosss
Katelyn does end up blowing Evan 26:32
@@ctrlundo XD
19:31
"Mine died."
"Can't have your vibrator die in the middle of it"
"We're in the middle of it"
"We haven't even finished"
Then the goop part 😟
😙 -“we’ll make do with one?”
“we’ll make do with one…”- 🗿
I paused the video on the product page and there was: "For the love of god, do not use in concrete". Well... now there is soda all over my keyboard.
I was about to comment that lol
now you're just missing a concrete mouse, pc case, cathodic monitor, and a cave to have a *historically* accurate caveman pc xD
I for sure read CATHOLIC monitor😂
@@onepurpleostrich Yes, a magical stone that shows Jesus xD
Omg I was thinking this exactly XD just go full Cave Nug XD
thats so funny haha
The number of people who would pay thousands of dollars for a "flintstones" pc rig is not zero XD
When they asked what looks wrong with this picture, I honestly thought they forgot the mold release 😂
S A M E 😅
I was thinking they forgot to make it level for some reason
Same lol
Same/
My husband and I both shouted “mold release” hahah
6:50-7:20 😂😂😂😂😂😂. Pure gold comedic timing. I am in bed, and my husband is asleep. I had to stop myself from laughing so much that I thought my head and lungs were going to explode. I was physically shaking so hard with suppressed silent laugher that the bed began to shake, and I worried even more that I was going to wake my husband.
So for the fiberglass one, it worked how it’s supposed to. Typically fiberglass strands are added to concrete that is being poured on a slope, but they don’t want the concrete to run. Like a boat ramp. It also adds insane strength to a compression strength test.
While I doubt this will be an issue for you guys, concrete can take 30 days or more to cure, sometimes leaking out moisture. If the keyboard stops working, that’d most likely be why.
If you have to redo this, instead of using the table, you can still use the vibrators and plunge them into the concrete straight in and out, moving positions each time. This will help prevent over vibrations and separating the mixture.
There is a surprising amount of complexity to getting a good concrete mix depending on your intended use. Every pour has a different ratio of cement, gravel, sand, water, and other additives.
Never thought my job of testing concrete would lend a useful comment like this 😂
Fellow concrete technologist..hi!
your pressure pot has IMPECCABLE comedic timing
Concrete tips:
Once a piece of concrete is solid, you can wet it again with more water to ensure all the cement powder inside is fully hydrated for extra strength. Concrete takes a long time to cure so you could actually just stick the tray of keys into a pot of water for up to a week to ensure it is as strong as possible.
There are some gorgeous concrete dyes that could work really well for projects like this. I don't think you can go as well as you do with the resin, but it can give some fun character to these projects.
Also, instead of sand, you can try fly ash or other additives in the mix for added strength. There are lots of sources online for which additives give what characteristics that I am sure Evan would love to research.
That is such a great tip! I had no idea that doing something like that would actually make concrete STRONGER. My family does a lot of DIY stuff and I'm sure this'll come up for me at some point - so thank you for spreading your knowledge!
i remember when they used to make DIY projects with concrete like coasters, I'm almost sure that they tested concrete dye at some point but they completely forgot the existence of it for some reason lol
what got me was submerging the concrete in water for more strength, I would NEVER thought this and it makes a lot of sense
Thanks!
@@keikouyeda1224 I read somewhere you can also use latex paint as well. For something this small it would be worth it.
Also sifting everything before hand would be super ideal.
thank you so much for scratching the structural engineer itch inside of me, oh my god I kept saying cure it! , wait for 7 - 14 days haha. I also saw the problem they were gonna face with the space bar (and the keyboard base for that matter if it would bend), of it just breaking because it is not 1) thick enough, 2) it is not reinforced!, they could have easily added a straightened paper clip as a reinforcement and it would have worked :D I would love if they saw both of our comments and implemented the fixes and maybe provide us with an update! it is such a cool video though :)
I laughed so hard at the sudden squeak I actually lost oxygen and felt like I was about to pass out. Evan and Katelyn killed me (almost) dying laughing 😅
Also respect to Katelyn and Evan for always using the necessary safety measures when working with all the different materials and tools!
"That does reduce the volume a lot-"
The cries and shrieks of the damned rise immediately
I watched that part a few times, laughing so hard
i actually cried laughing when that happened, me and my bf have moments like this all the time but we never get it on camera
ÄAAAÂÆÆEËEEEEEEEEEEEEEEEEEE 👹👹👹👹
Alternative pressure pot silencers is officially my favorite era of Evan and Katelyn. Closely followed by the "Did we Level?" era and the "Should we Mold Release?" era
Next one to try is an ultrasonic whistle. (The cat probably won't like it...)
Next try a whoopie cushion!!!
"It does reduce the volume a lot" followed by ear peircing shrieks is the new
"Wouldn't it be ironic of I dropped through the ceiling" followed by immediately dropping through the ceiling
the best part about watching you two is that you just genuinely love enjoy having each other in your lives, it is so precious Ɛ>
Right? The chemistry between these two is just plain incredible.
15:46 "Oh to be buried in goop" Resin time song at a funeral goes hard
LMAOOO 😂😂
Resin at the Funeral is like an AU Panic! At The Disco
"were gonna finish this time" is SUCH a perfect reply to 'we bought more vibrators'
Woah! I'm actually impressed by how effectively and immediately that little vibrator worked on the concrete. I figured it would help slowly, but I totally didn't expect it to practically liquefy the concrete. How awesome!
Okay but why is it so AESTHETIC and the typing sounds like beautiful rain pitter patter?!?! Amazing!!!
No one: nothing
Evan and Katelyn 1-2 years ago: Extremely family friendly, always forgot the mold release, worked with what they had
Evan and Katelyn now : concrete vibrators, lil jokes, have almost way to much equipment, Evan has a beard, Katelyn has better editing skills, they have merch, they have 2 presure pots, Jubi is getting drugged (catnip)
I wanna make a sitcom about this. Oh wait I already have this ❤ hilarious
Wait till you see the 3rd pressure chamber😏
And they still always forget the mold release.
We want more Jubi.
@@davidedwards1705 It's spelled Joobie!
I've been watching since the early days of the concrete coaster crafts and this video really feels like y'all have come full circle
for some reason, this makes me nostalgic for the concrete toast coasters ^^
What happens if you mix resin and concrete…?
omg yes, we did quite a bit more concrete in the early days!
@@Camerons16 it wouldn't go well because concrete uses water and resin doesn't react well with water
@@Nonbeany ahhh
The goop scene perfectly embodies why I love this channel
Evan's distressed "woawoawoawowoa" on the wobbly space bar made me laugh so much lol. I've never had the dream of rubbing my face on concrete but now I feel like I'm missing out 😂
I love the random things on the pressure pot lol.
The fact that the Amazon listing said to not use the personal item with concrete 😂
It’s funny they edited that in. However, one thing I noticed here that I totally missed in the OG video about vibrating concrete, is that the “personal” one is a NECKLACE?!?!? WHY would you wear THAT as JEWELRY in PUBLIC?!?!? OR AT ALL?!?!? That is so nasty, what the heck
@@DannyDevitoOffical-TrustMeBro
Yeah, I’ve seen a lot of weird “personal” ones like that. Necklaces, shelf “decorations”, ones that are supposed to look like squishy toys, it’s kinda wild how much people want them to be discreet but also out in the open.
@@ellespoonies some people have family or kids who might find their toy. if i lived with a kid or a parent id rather them find a little vibrating stick on a chain or something that looks like decor than Bob the big black bussy buster.
@@separatedfoxor just…hide it better? It’s so much weirder and creepier to leave it in full view. Leaving it on high shelves is a much more intuitive solution, and _doesn’t_ result in children actually thinking it’s a literal kid’s toy and trying to pick it up and play with it. Disguising it as a kids toy is the absolute worst way to keep kids from messing around with an adult toy.
@@DannyDevitoOffical-TrustMeBroas a child, my parents told me to get something out of their nightstand top drawer. They mentor bottom. Well I was searching everywhere for it because they kept saying it was there. I found a very obvious vibrator under a bunch of stuff. I would so much rather it be a necklace that I didn’t think of
Omg. I fricken lost it when that noise maker blasted off. That was such perfect timing. The universe does have a sense of humor sometimes.
That does reduce the volume a lot-" Universe: "heeheehee... you sure?"
All the intentional and unintentional innuendos in the video ending with Katelyn screaming "it's in" and later Evan saying "this was unexpectedly hard" absolutely SENT me. 😂🤣😂 And this was also a very cool project that resulted in one of the nicest-sounding and most cool-looking keebs I've ever seen. 👍One of my favourite E&K vids to date.
It’s my first time watching this channel and I simply love it, too loud and funny, a lot of jokes, so easy to watch and much chemistry between both ❤️❤️❤️❤️
"yeah_its_not_like_its_important" might be my favorite subtitle ever lol. Bravo Katelyn
I lol-ed so hard at that one!
Every time the Bad Noise occurred, the timing was absolutely perfect. Sorry to enjoy your suffering so much, but the way you both ducked like it was a bomb going off each time *chef’s kiss*
I absolutely love your videos! They always make me smile and everyone in my family knows who you guys are and we all love your videos so much, even my dad loves your videos. I have been watching you guys for about 5 years now which is kinda crazy because it feels like just yesterday I found your channel! I’m always looking out for new videos, keep up the great work!❤
Liquefaction is a wonderful kind of magic, like magnetism. Though we understand how it works, it's still so cool, and nice to see other people enjoy it as much as I do.
"It does reduce the volume a lot" I watched this multiple times cackling. Such poetic irony. That was amazing 😂😂😂
Me too
I am cracking up rn I watched it at least ten timess😂😂
Item name: *Concrete Keyboard*
Quality: *Legendary*

One of the few channels who's ads I don't skip!
"That reduces the volume a lot...... ?RF?LKN?RLKVFUUUUUUUUUUUUUUUUUUUUUUUUCLUJBADUC" I laughed more than I should have
Also, rhe editing of the videos is SO good and so funny. So many jokes and chef's kiss moments. It's trully a pleasure watching these videos
I rewound and rewatched the part where the party favor goes berserk multiple times...your reactions were hilarious!
hahaha the party horn really pranked us
😂 same 😂
I did too! lol Katelyn’s editing and their overall vibe/video style has gotten even more entertaining than it already was!
@@EvanAndKatelyn p-p-p-prankkkk!
Unintentional prank
when the pressure pot started squeaking i damn near choked on my lunch omg
Squeaking? More like SHRIEKING
@@LavastormSW xD not wrong
Same! Tears in my eyes! It sounded like a child crying
Thought you said "choked on my lung" which was a lot more concerning
@@rooness2184 Nah that's just what happens when I choke on my spit trying to breathe for the 18th time that day.
great video, awesome building montage, with the fast forwards and the music and all
I can proudly say I was like "WHERE ARE THE KNOBS?" just before spot the mess up lol! Only because I was just thinking about how genius they are while admiring the new molds haha
This is like a Flintstones inspired keyboard and I love it
I thought the same thing! Caveman chic?
I thought for sure Katelyn and Evan were going to come out in Flintstones costumes at the end
As someone who knows how concrete works, watching the chaos of you guys working with it is as entertaining as it is concerning
Yup. Chortle.
Katelyn starting after the add the shirt you're wearing looks like concrete and I think that's absolutely perfect
I like how you added "Coarse sand w/ cat hair", as though there's somehow no cat hair in the rest of them.
I find myself saying “Evan!” the same way in Smosh videos Chanse says “Angela!” when she goes wild
Wait what channel am I on? Lol
Based fellow smosh and e&k enjoyer
Omg a fellow Smosh fan, LETS GOOOO
Omg yess
Hell yeah, I just came from a smosh video lmao
10/10 we laughed so much during this episode, guys! Your sponsor skits are unmatched!
"✨😊~Commence the jiggling!~😊✨"is one the funniest things I've ever heard.
no-one:
evan & katelyn: we gonna make normal things-
no-one: finally-
evan & katelyn: BUT IN THE HARDEST WAY POSSIBLE (literally)
Concrete time, Concrete time, con con con con, Concrete time!
Resin time sounds much better 🤣
this would be so good with all the concrete projects in the background
Sweet jeebus. I’ve never laughed so much and so hard at an E&K video. Silliness overload in this one!
The goop segment brought me back to life 😊 thank you for your service
Evan: You know, honestly that does reduce the volume a lot!
Party blower: 😈
When other CZcamsr have a sponsor *skip
when Evan and Katelyn have a sponsor *watch ❤
seriously i was about to skip, but they just sucked me in they're so entertaining
For longer concrete casts like the space bar, I would consider embedding an opened up paper clip, I mean, some kind of metal rod/wire thingy as reinforcement, like a scale model version of rebar.
I was so incredibly high watching this and lemme tell you, the background music choices was impecable ❤
I love how unhinged yet simultaneously educational and fun these videos are lol Evan’s surprise vibrations made me laugh so much!😂😂😂
absolutely living for this becoming *that type of channel*
As a civil engineering student, i thoroughly enjoyed the video, pro tip: you can increase the strength of concrete by submerging the keycaps in water after demolding them.
Evan and Katelyn you are my favourite CZcamsrs Ang you guys are so amazing and talented
I'm watching this on my lunch break and 6:58 made me laugh so loud I had to explain to a coworker what was so funny 😂
and it happened again at 17:45 hahahahahah, still just as hilarious 🤣
the irony of the timing of that was just too much haha
@@EvanAndKatelyn so true hahaha, trying to prank Katelyn and ended up pranking yourself as well hahaha
What’s next? A cat hair keyboard?🤣
Pretty sure they all become cat hair keyboards
Cat hair in resin, like the rings those one folks make out of ashes and fur and other meaningful bits
Don't give them ideas
@@MrBuckleBuns hehehe
@@Aromantic_alien can confirm this is true
the concrete wrist pad is an ergonomic marvel
The editing for the Final Assembly is incredible
evan and katelyn really saw "work harder not smarter" and took it to heart
the comedic timing of that party horn was impeccable 😂
Never seen this channel before, but I gotta say: you two are some real life, grade A, bonafide DORKS and I mesn that in the absolute nicest way possible
7:00 had me in stitches. I just kept rewinding it. Took me 5 extra minutes to watch the whole video. 😂😂
K: "Woah, it's so hairy looking!"
E: "Get in there!"
E: "This is not flowing as well."
K: "Noo..."

HAHAHAHAHAHA I JUST UNDERSTOOD THAT 😭😭😭
my therapist: brutalist keyboard isn't real, it can't hurt you

The sponsor break was actually so funny! 😂
I think graffity inspired letters on the concreate would fit so well!
Eww, hate graffiti.
12:24 That little 1 second "Jump Around" one-shot was so funny and well-timed 🤣 I love Katelyn's editing! Loved the ad segue with the couple on the couch transition as well -- so smooth
That looks and sounds great!
I LOVED this episode! The jokes, the content, pushing the edge... ;)
I was always amazed with the liquefaction earthquakes sometimes create and using vibrator to liquify the concrete was super smart! Kudos guys!
Construction workers use a giant version of that when pouring concrete .. 3 or 4 inches in diameter and a couple of feet long, on an air hose that powers it
@@frontiervirtcharterthey tested one like that in a previous episode. But I'm not sure if it was that big.
It's been maybe 1 or 2 years since I started watching this channel and I always felt so comfortable and familiar with you too, but never understand why
Today I realized that you two had the same lovely energy than a CZcams couple that I liked to watch when I was little (9 years ago). They stopped to post a while, but it always will be a good memory in my heart
And now I have you two, little lovebirds, who make me laugh everytime
All good vibes for you ❤

@@sourcererseven3858I'm using Google translate when I'm especially interested!
Okay now moss on the wrist rest and a resin pond desk mat! Love it!
this channel is so amazing, its educational, but so freaking funny
The broken spacebar's crack perfectly lined up with the crack on my screen 😂
This is too relatable
I make concrete ornaments, using fast setting cement. Sometimes fine sand in the mix, as I like to sand them smooth. I then paint them with 3/4 coats of white emulsion ceiling paint, until no more can be absorbed. Then I paint them, finally coating them with 3/4 coats of outdoor varnish, or 1/2 indoor varnish. Or if pressed for time, spray varnish. I usually top up the varnish if it’s gonna be a cold winter.
Unfortunately, my healths been more limiting these past few yrs, so they all desperately need attention.
Well done guys. I didn’t think it would defeat you!
The aesthetic is really nice.
I'm so glad you take your health seriously and always protect your lungs. Way to many CZcamsrs don't.
Especially when working with fiber glass. It's so fine and terribly dangerous if inhaled
6:58
“You know honestly. That does reduce the volume a lot”
“It does-“
//violent screeching//
Comedy gold. Can’t believe I laughed out loud on the train because of this
17:48
Sounds like someone is f-ing dying lol
I am happy to see you are finally taking the levelling serious... 😂😂😂 and it's not an Evan & Katelyn video without the magical substance called Resin 🙌🏼
I LOVE YOUR ENERGY SO MUCH
Evan & Katelyn, delightfully dorky in every good way. 💞
it's always a good day when evan and katelyn post
I woke up anxious today. But within 30 seconds of clicking on this (around the time you guys were playing paddy cakes), I could feel myself smiling. You two are like human serotonin. Thanks so much for sharing.
28:22 The Void plush is so cute! I love it
Brutal!😱
Minimalist!😳
I loved ❤️
7:05 "that reduces the volume a lo....SCREEEECH". lmao that will be the internet benchmark of speaking too soon
The comedic timing on the party blowout 6:59 is *chef's kiss*
I add pva glue to my concrete and plaster projects it makes it very strong, you are basically adding a plastic vinyl material and it binds very well to things like this. I also add fine cotton fibers this increases strength of pieces a lot in combination with the glue which adds a bit of flex which help with cracking.
It actually sounds so good though haha. And it does look so smooth. Relaxing.
