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

“Mom Phineas and ferb are playing with reality again”

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.

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

The person who animated the sphere: "My goals are beyond your understanding."

It feels weird watching this without the incest

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

i feel like i've just learned some forbidden knowledge

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

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

i can't unhear the brother and sister argument

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

Ancient VSauce

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

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

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

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

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

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

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

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

Two siblings talking about spheres. How lovely 🥰

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.”

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

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

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

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

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

its weird hearing this without the arguments and incest

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

this feels like a tutorial on how to escape reality

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

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

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

I can't even fathom how much specialized knowledge you would need to even think of seriously asking this question, math is wild

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

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

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

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.

Normal version: 🧠🧐 Huggbees comedy version: ☠️💀

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

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

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

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

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

Alternate title: two people have a candid, respectful, academic conversation They were so polite and friendly-formal with each other

So this is what math teachers do in their spare time

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

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

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

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

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

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

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

This sounds like two self-aware AI talking to each other.

I remembered this video and accidentally clicked the Huggbees version first. For a while, I was scared that there was only one version. What a relief that there is the good version too.

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

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

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

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.

i can’t believe i watched all of this without getting bored. educational brain rot

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.

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

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

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

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

I keep waiting for the incest plot twist

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

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

It’s kinda cute how the woman is very patient with the man and is explaining it over and over without getting annoyed or frustrated

What a relatable relationship between these two

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

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

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

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

its nice how someone didnt divorce during this

*Kids in science class years ago:* "Man this is so boring!" *People on youtube now:* "I might as well watch this for fun"

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

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

this is a lot less traumatising than that one

This is the most polite argument I've ever heard

Math teachers: "Trust me, this will all be useful in the future." What it's actually useful for:

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

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

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

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

I absolutely love how nicely they talk to eachother

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

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

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

Rip to the people that got the wrong one 🙏

Why does this feel so unsettling?

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

after watching this, i feel like i know everything and nothing at the same time

thanks youtube for recommending this 12 years later. i understand nothing that's happening but i like this style of video, reminds me of watching educational videos in elementary school :)

I'm too used to the Huggbees version
