Hi
Floaty table (clearly not)
Hello, that floaty table is amazing!
@EvanandKatelyn, say the name Oliver Clothesoff!😂 And by the way you guys are amazing!
Hi
I find it funny that editing Katelyn always has to fill in Evan's words because he keeps forgetting to finish his sentences lmao
duh
I've got no idea what you
@@RonByg mean?
You mean when
@@richard.d_ I'm an engineer, and the vocabulary for tensegrity escapes me everytime I see one of these structures. Cut the guy a break 🤣
I need a house tour to see where all of this furniture goes lol

@@m3nac345 it's still in their living room, but theirs no other footage of Joob using it (unless it's on Twitter or Patreon or something)
@@lindsitruelock5632 shut up
I love how they explained how it works and yet I’m still soooooo confused
I don't get how the center string is pulling in opposite direction.. I feel the need to get to the bottom of it😅
You know how when you pull on a rubber band and let it go, it doesn't just fall? It has a spring to it? It also becomes longer and thinner, right? You pulling on the elastic causes an internal force to form within the band. This force is released when you let go of the band or when the band snaps. When they tighten the strings, they're adding tension. The tension withen the string, it's enough to hold up the table.
@@excess_alex.mp4 cool I do understand that now
@@taju999 top table-piece wants to drop, the middle is below the bottom-tablepiece - making the middle string straight
@@ayoCC oh woah! Finally I understood
At the end, Katelyn was like the overprotective mother while Evan was the dad messing around with the kid.
Yes

Haha thank you!! We were so relieved it worked!
@@EvanAndKatelyn The tensioning worked great :O

This is probably one of the few channels where your models consistently actually look exactly like the outcome. Nice job guys!

6:30 high five, right in the eye
Classic Evan and Katelyn lol
😂😂❤️
He also nailed the high five if you think about it lmao
A good way to know if the strings are in the same tension is to make them vibrate like a string instrument. The lines will be in tune with each other if they have the same tension. Keep in mind the vertical lines will sound different than the diagonal lines.
Or just let gravity test it?
Ooh I like this! Although it would only work if the lines were also *exactly* the same length to begin with... I imagine they ended up with a slight tension differentiation to compensate for the slight length differentiation they got when cutting the lines
@@cameronmueller-harder3916 why would the length of the string matter? wouldn’t the pitch only depend on the distance between the two ends of the string if they’re all the same tension?
@@canadianchemist5052 That's a very good point, it's not at all intuitive! Here's a way of thinking about it that makes it a little bit more intuitive: Picture you have two elastics that are super super stretchy. One is 11 inches long, and one is 1 inch long. If you stretch them both to exactly a foot long, the 11 inch one is going to make a relatively medium pitch noise, but the 1 inch long string is going to make a *much* higher pitch noise! (*wistful sigh* don't you just love logical extremes?) Obviously their strings are much closer in length than 11 inches vs 1 inch, but if two are about a half inch different (one was a quarter inch too short and one was a quarter inch too long, say), they could totally make noticeably different pitches!
Oh wait I think I misunderstood your argument, sorry! This is definitely super counterintuitive, and I have no way of making it more intuitive... if two strings are the same tension, it actually doesn't matter how long they are at all! An inch long string stretched to 2 inches will make exactly the same pitch as a 10 inch string stretched to 20 inches. This feels super wrong, but it's totally true (as long as the strings are completely identical in every other way)! This is why tensioning the strings using pitch won't work... because if their strings start as different lengths then they actually don't *want* them to be the same tension!
Again, let's take it to the logical extreme. Let's say their strings are supposed to be 12 inches long, and one they accidentally cut to be 10 inches and one to 14 inches, oops! They decide to use them anyway, and tension them using pitch. If they make them the same tension, then one leg of the table will suddenly be 10 inches tall, and one would be 14 inches tall! This is why they tensioned them the way they did. This way they were able to counteract any small differences in length. In this example extreme case, it would mean tightening the 14 inch string a whole lot. That would then mean the 10 inch one and the 14 inch one could be in equilibrium with each other (although probably not, given how big of a difference that would be), but they would be at very different tensions, meaning very different pitches!
This has got to be the best tensegrity table I have seen! So solid, great work on both the engineering and aesthetic side of it!! 😁
I have seen a few of these and this is the best, the multiple and diagonal lines are genius.
Evan, “Remove the blue one.” Katelyn, “They’re all blue.” Good thing you aren’t defusing a bomb.
lol good thing!
I think this calls for E&K to play Keep talking and nobody explodes on their gaming channel
@@johnccena I would love to see them do that.😂
@@Kai_Patton_Lilith its a game where 2 players diffuse a bomb, player 1 has the bomb in their screen, but player 2 can NOT see the bomb. Player 2 has instructions on how to diffuse the bomb but player 1 can NOT see the instructions. Player 2 has to guide player 1 on how to diffuse the bomb. its kinda fun
Oh! They should totally play "Keep talking and nobody explodes"!!
This made my day, you guys are so wholesome. Magician Pro tip, black line is less visible than transparent line!
It's not that I don't believe you, but WHY? Do you know the brain/eye mechanics behind this?
Cool. I did not know this.
@@Danutty
Just a guess from general crafting experience: clear fishing line is very shiny, it reflects light. That makes it much more conspicuous, than one would expect.
oooh I like that pro-tip. It actually makes sense... I think.
@@raraavis7782 That's why puppet strings are always visible on TV.
You two should be guests on Good Mythical Morning. The chaotic beard intensity of Evan and Rhett would be amazing.
I like the way this turned out. It's really pretty and would look so nice as a coffee table or just as decoration!
was anyone else having massive anxiety that the string was going to snap and slap evan in the ankle? god
I thought he was gonna step on the other side of the board and get smacked in the head three stooges style
With 200 lbs test line, nah.
Yes... I literally looked away like it was a horror movie!
@@Aeguis yeah but my issue being with 200 lb test line it could ALSO inflict some Very painful wounds if it did snap
... no

It would have been a huge pour though
"It's ok let go lol"

That whole time I was screaming “PUT DOWN A DROP CLOTH!”
I spent 27 minutes just watching in complete awe.
You 2 are aesthetically and intellectually far beyond the RUclips DIY channel standard.
You guys are just magical beings.
Speaking of aesthetics, I keep thinking that Katelyn should do makeup tutorials, particularly when I see her eyebrows and eyeliner. 😂
your words, they are too kind! thank you ❤️
I does speed up the video
The site Chemical 14 built one of these out of steel about a week ago.
I love these videos but i feel soooo alone the entire time :'(
I really appreciate Evan’s engineering of this project. That is a skill I have no training in so I really admire him.
Tension physics is relatively tricky as well. At least when on a scale where you’re trying to hold up a lot more weight. But still something like this can still be a bit of a challenge especially when dealing with the twisting force as well when only having basically a single line in the center supporting the weight of the top. A cool redesign of this would be to have multiple little stems jutting out from the bottom and “hovering” between each other, allowing for more support for the weight and by spreading the load out further it would also keep it more balance and less wobbly right off the bat. Another thing they could have done was design it in a way that the support lines ran to help keep it from twisting could have been placed so that they ran right across another line, and could have used like an X connector to almost tie those 2 separate lines together, so that when it wants to twist, the tension of the anti twisting lines helps, but those also pull on another line to help keep it rigid as well. There’s so many cool things you could do with this to improve it but for the basic design they were after and for not spending a ton of time trying to design it to be perfect and doing a bunch of trial and error, this is very well done
2:06 That hit home so hard Evan! I hear ya buddy.
9:17 The drill was synced with the music.
Oh I think so
Omg ur right
It is synced
I can't unsee that
Oh NOICE
the amount of times evan didn't finish his sentence is equal to the amount of times katelyn freaked out
😂I thought I was the only one who noticed, she needs to calm down like alot
Same
You ain’t wrong
‘Words are hard 😁’
I dont blame with the amount things and times these projects go wrong i really dont blame her for freaking out XD.
I love E&K because their background fields of engineering and design come together so beautifully because they’re so in sync with each other.
Evan clamping everything together to support it,
Me clamping my life together just to have the tiniest bit of stability
That is unbelievable, absolutely beautiful and so imaginative. And as an aside, I could watch a one hour video of nothing but Katelyn being Katelyn. What gem you are. Great personality, sense of humor and absolutely beautiful. You are one lucky boy Evan.
Evan: “This is going to be complicated.” Me (completely incapable of doing any of their projects- even the ‘easy’ ones): 👁👄👁 got it 👍🏽
haha, when Evan says it's complicated you know it's EXTRA complicated
Just watch it for the aesthetics and funnies 😂
Lmao i like that face
@@EvanAndKatelyn it's thanks to his engineer brain isn't it 😂
@@EvanAndKatelyn the video was 2 hours ago but Evan and Kaylyn responded 3 hours ago
Omg when Evan said to turn the camera off because he didn’t know what he was doing. I literally can’t stop laughing 😂
haha, i'm glad I kept filming!
EvanAndKatelyn thank u. This has made my day.
I dont think u need the when😂
@@EvanAndKatelyn hi evan and katelyn luv u UWU :3

Excellent concept. Excellent planning. Good job.
Put it in the front room and use it for an occasional table.
Your happiness just make me smile all day, thanks

I read this comment as “these insults for Endeavor are getting less creative” and I’m currently equal parts disappointed and in total agreement
Evan: Messes with the project (slaps and or wiggles it)
Katelyn: *noises of concern and or disapproval*
Evan: Continues messing with the project
it really do be like that

Random thought: what if you made wearable “glass slippers” out of resin? 🧐🤔
y e s
That would be so cool!
Tensegrity slippers
MATEEEE you said this 3 times!!! Quit it
MinniMia no ✨
Some ideas I had : You could make the wires that go from the corners go diagonally to their opposite corners - that would mean they would all cross in the center which IMO would make it look even more impossible. To prevent wires from rubbing against each other you can offset them slightly so they don't exactly touch.
To make it more stable I think you could put a weight on like you did when testing so the wires give a little and then tighten the tension rods while the weight is on.
When the weight is removed again it should now be super tight and more stable.
That wouldn't work though. The whole point of the wires around the edge is that they stop the tabletop from tipping over. If they go through the middle then they won't be doing that.
Thank you for not unepicly getting alot of ads on this video
science I learnt at school: [ ]
Science I learnt from "science adjacent with Evan and Katelyn": [ ]
I prefer Science-ish. Adjacent sounds silly.
@@ChrisPage68 I think that science adjacent is the better label. Their vids are more engineering than pure science so 'Science Adjacent.'
And that is why we should watch these videos in science classes instead of doing other stuff
I just love the whiteboard that says “JOOBIE WANTS HAAM”🤣
just a reminder to us hoomans in case we forget
EvanAndKatelyn haha i love this thing I was thinking maybe you guys could create a diy resin nuetons cradle
Yass
What time stamp?

I have no idea which videos I watched and/or which channels I followed that led to this being suggested, but I'm so happy for the algorithm right now, this was amazing
Awesome! The colors are absolutely perfect! Shows it off beautifully 💙💜💗
I just want to say I really appreciate the googly eyes on your tools. I'm having a really bad day with my health and I saw the notification and went to watch because your videos always make me laugh and I'm really enjoying the googly eyes today. Lol.
Evan: Oh this makes me nervous.
Evan immediately: *goes to get Katelyn protective glasses so she is saver*
If this isn't a cupple life goal, then I don't know what is!
firejeco I mean...he didn’t want her to get stabbed in the eye
My heart melted when I realized that

14:42 the disappointment in her face 😂👌
The whiteboard that says “JOOBIE WANTS HAAM! 😺” is adorable.
Joobie wants to make sure we don't forget
Ha yes
Manager joobie wants and is paid in ham.
@@EvanAndKatelyn Ah yes, lets not forget to level and mold release the ham.
Haaaaam
So just an idea... To increase the strength and stability of the table, while putting the 25 pound weight on the table, tighten the loose strings. That way when the weight is taken off, the strings are tighter and more sturdy.
Wouldn't that cause additional stress to the wood/strings since the tension would be higher than what's needed to support the table at equilibrium?
@@alixnight5318 it would at least partially depend on the stretychness of the material. the wood looks sturdy enough, but i wonder about the string(i think it's fishing line?).
NO! IS ALREADY PERFECT
Well done. Thank you.

I wish I had the skills to make something like that.

I think you can buy them in a DLC pack
U wish
you have it... with skill share! (har har har)
That moment when Katelyn stops trusting Evan and refuses to let go of the thing is so precious! I laughed so hard, that's so relatable! That table though!! Love it!
this is one of the nicest things i've ever seen on the internet. i want this in my house.
I noticed you accidentally left the tensioners out of your material list.
Looks very cool, and it's sturdy! Nicely done!
Anyone know what the tensioners are called?

But yeah, I could totally see that connector popping off and ricocheting excitingly.
yea he definitely shouldve had pants on in case it did snap so thered at least be something between the line and his leg
and the roof is just like NO
Pokes her in the eye doing so?
Nope, ‘twas the high five that got her.

This item is so mind blowing you guys should just make another video making one, maybe with some sort of twist, or a different type of tensegrity table.
OR A TENSEGRITY CHAIR

Watching Evan standing on the wood was like waiting for a balloon to pop
would of been so cool if the middle bits were transparent colored resin and the base and top were wood. Since they are the resin experts.
Might've been to heavy to work then.
should try to use leds to see if the fiber will act like a fiber optic and illuminate while on the table
Katelyn: literally crying
Evan: Square space! One stop shop! Templates! Domains!
So maybe someone else pointed this out already, what makes your design your design infinitely better are the diagonals. Without only vertical tensioning elements you have nothing to prevent it from twisting around the vertical axis.
Really really nice design for tensioning under the table, well done guys :)
Cat ignoring table IS providing approval 👌

@@HettieB8 I don't know how much 25 lbs is, is a floating stool an option?
@@meloD30 yes if you used something else with higher tensile strength. Fishing line will actually stretch and become more brittle at the higher weights for which it is rated at. I think some chain links could be used to make some cool floating stools (although I haven't made a tension table in a decade and a half at least). The challenge there is that you can't make the same micro adjustments with links of chain that you can with fishing and the stability depends upon the tensile forces exerting equally and exactly..... so theoretically yes, but not I nor anyone I know personally has proven the concept lol
@@ehrmanehrmann7115 my brain hurts from reading that

Here is a tip form a magician, if anyone is going to build this project I would love to see someone try using black thread instead of the fishing line.
If you want thread to ‘disappear’ and seem invisible you want matte black and as thin as you can get away with.
Fishing line is pretty shiny and reflects a lot of light. I think it’s designed for how light behaves in water. Either way it might be see through, but pretty bad at being invisible.
Black absorbs lots of light, and if its thin line our brains sort of ‘fill in the blank’. Even if it’s in front of like a green patterned wallpaper.
I think with black thread it would completely despair with just a little distance. I don’t know what distance, but from some distance you will see the table floating and see no trace of the string.
Evan’s design with more strings also allows you to use thinner string, so the design also make the string more invisible.
I think the issue would be with the tensile strength of thread. As someone who sews a lot... most thread really isn't that strong. I imagine you could get some, but you'd probably be better off using fishing line painted black.
Yes something like lanyard string. Black Matt DOES disappear in a black background.
Yeah, whatever the thinnest matte black material that is strong enough you can get a hold of is what you want to use.
The more true black/dark and matte the better.
You still could use fishing lines until carbon tubes are reality. But you could colour the fishing rods with vantablack ?
Ooooo that makes sense
SUPER FANTASTIC!!!

First saw one of these about 4 or so years ago. Was in the middle of building one when I had a stroke, still haven't gone back to finish it, but I will. Since then I have seen several different designs and even use of aluminum and acrilics, as well as wood and metal, in some of them.
