Graphic Designer: "You want me to animate what?"

I feel like this is what plays in the lobby of purgatory.

took me 11 minutes to realize this wasn't the one where they start arguing lol

Ah yes, the interaction between the narrator and the viewer is so nice. No one is shouting at each other, calling each other names for being either too smart or too stupid or talking about their unrelated-to-the-video past. A simple, calm and level-headed interaction between the educator and the learner. Completely no need to, I don't know, make them siblings or anything.

"man, this blunt is weak af" 15 minutes later

This is like one of those dreams that makes perfect sense while you're having it but upon waking seems totally nonsensical.

This may seem unrealistic in any real world application, but it's actually one of my favorite party tricks. You have to see the looks of peoples faces when I turn a watermelon inside out

Something about complex, high-level mathematics being explained like it's kindergarten video is oddly satisfying

the guy was able to ask all those questions without being embarrassed for not understanding and the lady wasn’t mad at them for not understanding like man, if only

these are the type of dreams you forget when you wake up

The fact that there is a normal version of this makes the insane comedy one a million times better.

“Why do you think mom and dad have the same last name?”

This gets even more cursed once you realize that this is the only video on the channel.

Notice how this was fun and educational at the same time but if your professor/teacher assigned you to watch this you’d probably hate it.

i can't unhear the brother and sister argument

It feels weird watching this without the incest

It's like you got abducted by aliens from another universe and you are being forced to learn their laws of physics.

"we did something impossible, heres how" "just use an impossible material of course"

"You have a lot to learn about turning spheres outside in" -Huggbees.

This conversation between two siblings is absolutely surreal to hear. What a beautiful relationship!

This sounds like two omniscient beings conversing on how to create a stable universe.

“Mom Phineas and ferb are playing with reality again”

Somewhere out there, a teacher saw this video and played the other one to their class

i thought this was the parody version that slowly devolves into chaos because of the narrators’ personal history with each other but the original is actually pretty neat

“That’s no good, you are pinching it infinitely tight.”

This just feels like two gods playing with physics in their own personal dimension/plane of existence

In an alternative universe where the siblings didn't argue with each other

Ahh! Who'd ever dub this super educational program with two narrators cursing at eachother and them getting frisky then actually being siblings instead??! 😄🤷🏾‍♀️

this feels like a tutorial on how to escape reality

"guys look I found this cool material that can go through itself" **Accidentally folds it** "Shii-"

I scrolled perfectly to the “this is not what brother and sister were meant to do” part and i was disappointed to find that it’s just normal here

Two siblings talking about spheres. How lovely 🥰

“If you insist” and “Here goes” will remain the most human things she says throughout

You see, the funny thing is that I would never watch this if told to, but because I found it in my recommended I watched all 21 minutes

its weird hearing this without the arguments and incest

Okay, this one doesn't end in an incest debate.

i like to imagine this is their purgatory, where the woman is damned to explain the inside-outside sphere over and over again, and the guy punished to never fully comprehend, for an eternity. Like Sisyphus' rock, but a math equation

No matter how far you try to run, UKposts will always bring you back here

RIP the people who clicked on "How to turn a sphere outside-in."

People who don’t know about the other video: 🌝 People who do: 🌚

These two are the entities who are talking to each other in Minecraft's ending.

My blanket in the middle of the night when I'm trying to find a damned corner

Such a great video! No screams at each other, no inc###, no naming the other and no divorces!

This is one of UKposts’s most mysterious videos. The comments. It’s theme. The 90s graphics. The gods.

This is how it feels to figure out how to operate someone else’s shower

these are the kind of shit you would watch when you’re sick and can’t move

I'm glad these two have a great relationship and don't get off topic.

Math Woman: it is surprising, but watch this: **sphere goes old testament angel**

“Do you expect me to believe that you can invert a sphere but not a circle?” “YES”

The last time I watched this was before starting college. I'm now in Grad school studying mathematics. It's fantastic how absolutely dense this movie is with math concepts explained at an elementary level. The whole section explaining domes, bowls and saddles is a very intuitive explanation of Morse homology and the Euler characteristic. It's also surprising to see that David Ben-Zvi worked on this, a name I recognize from a lot of topics touching Geometric Langlands and Mirror Symmetry

"Sometimes i feel like i'm on the outside looking in..."

Him: “I still don’t understand. Is there some other way to look at this?” Her: OK. 😐

"Watch out:" *soul dematerializes into the ether* * "That's a sharp corner"

I got confused man, I thought the other joke was the original lol

So nice. Imagine if someone stole the footage and turned it into a gradual descent into talking about their past and discussing incest and cheating. that would be funny indeed.

This is what our parents hear when we try explaining that we can’t pause an online game.

Can you imagine the look on the guy's face sitting at his Silicon Graphics workstation when this was brought to him to animate

Normal version: 🧠🧐 Huggbees comedy version: ☠️💀

Reminder: This is not the two siblings who slept with each other video

i feel like i've just learned some forbidden knowledge

This feels like the female voice is an omniscient god explaining the 4th dimension to a deity-in-training

i thought this was the meme version and got so confused when it continued to be educational

what the fuck? I just watched this thinking "oh this video is hilarious I haven't seen it in forever" and then the video ended while I was waiting for the jokes to kick in. I just pranked myself into learning topography for 20 minutes

Its taken me 10 years but Ive finally understood what tf they did to this sphere.

I wish my parents were this calm when they fight

If you ever think your school presentation is useless. Just go back to this hood classic.

I keep waiting for the incest plot twist

I love how this video anticipates where you’re going to get confused and has the dude voice ask for further explanation

I feel like I have learned everything and nothing at the same time.

“That’s not what a brother and sister are supposed to do!”

What a relatable relationship between these two

it feels like an ai and a human trying to comprehend the universe together

I'm too used to the Huggbees version

This is the weirdest episode of sesame street i've ever seen

"Can I see that from pole to pole?" "Damnit, Derrick these things take a month to render, it's the 90's"

“It’s MY Sleepover and I get to pick the movie!”

Why does this feel so unsettling?

Vocal - 100% visual - 100% Dancers - 100% Song - 100% M/V - 100% Instruments - 100% Beautiful - 100% Queen - 100% Fan - 100% Handsome - 100% ssgelm Never disappoint! 🐇

It's like watching a video of an elder goddess teaching a young god how to manipulate his newly acquired realm. Slowly, but surely, he learns how to use his abilities in order to bend his realm to his will.

"It is surprising, but watch this!" Proceeds to do something unthinkable to mortal man. "That wasn't easy to follow, was it?"

Imagine actually wanting to learn math and seeing all the comments talking about there “peaceful interactions” 💀

I saw the cursed version of this...

16:27 Man: "I still dont understand, is there any other way to look at this?" Woman: -pissed silence- "okay"

The power of late 90's graphics is pumping inside my veins

POV you're trying to find the long end of the blanket

"Someone should create a movie about this!" Famous last words

I'm glad someone finally figure out how to turn a sphere inside out without poking holes or creasing it

this feels comforting, yet unsettling. it’s like purgatory

This video is pure ASMR. Soothing voices, nice and pleasant sounds and very short musical plays. Love it.

Im sure I saw a version of this video were they constantly insulted each other, this literaly feels surreal because this is so calm and the other version was so unhinged

Imagine being the person who thought all of this in his head without an animation to help

random guy on the street: I’ll give 5 dollars to anyone who can invert this ideal sphere me: hmm

this feels like two 4d entities having fun in a 3d world and i love it

I am glad the two siblings have an ordinary relationship with eachother.

And to think that this video is actually from 1994.....

Imagine showing up to science class in 2001 high af and the teacher turns this on

This dialogue is top tier, their exchange is honestly great! And at the same time *Creates a problem to solve the problem* 😂

Rip to the people that got the wrong one 🙏

Mathematicians go insane because they have videos like this playing in their heads several times every day.
