Through one hole or two?

[5up3rp3rs0n]

A ghost moving the clay! aaaaaaaaaaaaaaaaaaa

[musicmuscle123]

...a torus and which is the remaining "handle", allows the intersecting bar to be viewed as intersecting different or both holes at any time. This double-holed torus never really needed to be transformed for the holes to be intersected differently, but transformations can exemplify one reference, even though all are valid at the same time.

[musicmuscle123]

HOWEVER, the main problem here is that everybody is looking at the double-holed torus as one object, when really, it is just 2 objects (tori) intersecting each other. however, spaces can't be jointly occupied so an observer has to select which torus gets to be whole and which is sheared to look like a C.This allows the C to openly slide along the main torus, exposing that it creates truly 3 holes (since a torus can be "split" its almost like have 3 C's). Switching references of which C's make..

[musicmuscle123]

I don't get the fuss. There is no strange topological property here. You just have to remember, that math, and geometry in particular, tell us that objects can self-intersect without creating singularities. With this in mind, it already tells us some weird things can happen.

[the3Dandres]

stop motion ;p



[BigWeebz]

this is fucking stupid. of course you can do that with a figure 8 made of CLAY that you CLEARLY MOLDED AROUND THE POLE hahahaha

[jrhinson]

I don't understand what is supposed to be so fascinating about this. The clay was just molded around the bar, was it not? Pretty sorry for a "magic trick".

[MyOverflow]

@jrhinson If you understood the topology behind it, it's actually fascinating.

[WoopWoopDk]

wow... you dident open it behind the stick... no no... not at all... fake stop motion lolol

[rroms]

i thought it would be more hardcore because of the video title

[planetmeagher]

@rroms i get it

[RawrberryPoptartz]

This isn't a magic trick.. It's called molding the clay...

[TheEskimoDance]

What is this wizardry?

[Elocho17]

again in the weird part of youtube

[AudioJustG]

"Through one hole or two?"

Thats what she said...

[MarshalltheArtist]

@AudioJustG Your mother didn't give me that limitation last night!

[ProducerSkeleton]

Clay... How stupid do you think we are? Of course a stop motion video of clay can bend the laws of physics. [It's Claymation]

[firebeast1025]

its bend



[TrollingYourButt]

bullshit, easy to do when you use clay, try it with something where the loops can't be changed

[HowOriginal03]

nice :D

[Spartacusi23]

thats wat she said

[nikkil001]

haha cool

[winhugs]

The double torus has a 3-fold symmetry realizable in 3D Euclidean space.

[Regginyaga]

Heresy

[Sonny0612]

i gonna try that on my girlfriend

[RawrrItsFaith]

*cough* playdoh *cough*

[oddnamera]

this looks like it was done with play doh

[ExquisiteCombos]

@oddnamera it is,or else u cant remake the spheres to do that......

[divdawgd]

You broke the loop, sorry.

[sleepdrinkandkill]

he moves one hole and sticks it in the middle

[Guitarledgend0123]

Sorry, you broke your own prerequisites.

[lely2cool]

EASY!!!

[Musashi242]

you broke the loop once you changed the molecular structure. once again, egghead scientists stupified by the obvious.

[jobriq5]

@Musashi242 this has nothing to do with molecular structures.... its a topological abstraction, there are no molecules this is just a demonstration

[TinyMike111]

If I wanted to see it again, I'd just click the time bar.

[DanielDownNdirty]

your mom has 3 holes and me and my buds will happily fill them all trollololol

[PoliMeim]

@DanielDownNdirty or, hows about me, you, and your buds have a big gay orgy. That would be fun! we could cum in each other's mouths, fuck our brains out, swap blow jobs, and just have an over all good time. Heh? Heh?

[DanielDownNdirty]

@PoliMeim ill bring the poppers 

[PoliMeim]

@DanielDownNdirty !!!! :D

[fatalus553]

@DanielDownNdirty XD

[fatalus553]

@PoliMeim XD

[fatalus553]

@PoliMeim XD

[koerund]

to ur username, if u could divide by zero then every value (lets call it x) would be equal to its double or half: x = 2x or x = x/2 (i can proof this, im not making baseless claims)

[noeltrixie]

wait, how much is the clay in ur country?

[epsdelta]

Of course... Damn you Topology!!

[6eggc]

one cock 2 pussi

[DWarrior666]

shopped imo

[amerikanits]

very clever

[jesuslevrai]

FAKE

[Psp4804]

@jesuslevrai Nah.

[HappyIsFleeting]

@jesuslevrai No, very real, I can do this after watching the video in its entirety. And she/he never broke the loop.

[bleak95]

@jesuslevrai are you kidding me? Simply out of your lack of understanding you claim it fake?

[numberonedbzfan27]

@jesuslevrai you trolls are getting on my nerves

[Chimb111222]

44 People couldn't say "Topological" then tried to figure this out and FFFFUUU'd

[THeBodhi1000]

het is gewon klei

[gonzal05]

Not Impressed...

[Kabitu1]

I know you´re not cheating, but it kind of looks like it at 0:24.

[Mjheiko]

mit knete ist das auch ganz einfach :)

[chadmuks]

that's what she said. well, i tricked her and went through the three holes anyway.

[Dragonicafan]

that's what she said

[ArtemDubas]

THAT IS STUPID !!

[minitos1]

through your hole LOL i didn mean this :)

[ricktbdgc]

good tune, crystal method i believe

[deciett]

I'm a chemical engineer and just looked up topology. It's a pretty cool concept and probably plays no small part in advanced spatial problem solving, I just don't see the point of something like this overall though. Too practical for this pure mumbo jumbo >.>

[Kurzula5150]

Love that, that is really good and benefits entirely from being demonstrated with a tactile and easily reproducible medium.

[Islanders1932]

As a math major this does not make sense to me....can you cut out that form on a piece of paper and do it? Or does it only work because it is clay? I feel like you are changing your original holes with the clay in order to do this. If you could please do this with a piece of paper it would really help me understand better.

[zer0dahero]

@Islanders1932 The only condition was that the loop is not broken, no other condition was stated.

[ICantStopYourMemory]

@Islanders1932 paper is flat, nonelastic, etc. Many reasons this would not work. i don't understand how you are a math major... then again i guess you will just teach kids how to do long division so don't worry about it.

IF you are interested, look up eversion of a Sphere. should explain better than anyone can in comments.

[daofeishi]

@Islanders1932 As a fellow math major, I highly recommend that you take a topology class.

[FenBolds]

Topology is awesome.

[ZeroSubscribe]

clay was my first thought

[wolke14]

quite fantastic! Difficult to understand but I thin i got it... or not?!

[euklid216]

brainfuck

[nuladee]

the two holes are homoerotic

[NarutxSasu]

topology is the study of the earths layout above sea level. how is this topology?

[UzumakiAang]

@NarutxSasu

Topology is also a branch of mathematics. Look it up on wiki!

[Crayzerkade]

@NarutxSasu You are thinking of Topography :) 

[Pinmanqaz213]

clay!!!!!!!!!!!!!!!!!!!!!11111­

[imilkdude]

my head nearly sploded.after seeing that witch craft shit

[waltdisney35]

clever!

[MultiMusicMind]

Still through one loop Haha, you look through 2 but in the back its only one loop which the stick/bar goes throgh

[NutsandGuts]

my head asplode.

[jjsantos81]

i dont know what the author wants to prove, but a topological space with two holes is not homotopical equivalent to a space with only one hole...

[jjsantos81]

@DavidSpieluhr u are wrong. a figure with two holes and a figure with only one hole are not homemorphic,.

[DavidSpieluhr]

@jjsantos81 lol, noup! you are wrong a torus of two holes is homeomorphic to three "lines" intersecting just in the beggining and in the end, suppose they have an order clockwise (lets say line 1, line 2 and line 3) they can exchange order even by means of an odd permutation (that is what happend here) by menas of a simple transformation

[allispaul]

@DavidSpieluhr But this doesn't prove that a figure with 2 holes is homotopic to a figure with 1... what are you talking about? It's pretty easy to disprove, in fact, if you want something really elementary you can just triangulate them and find their Euler characteristics.

[spar130]

hey,uh...space cadet come back down to earth i mean thats not possible to put thread through a metal stick!!!

[sskittl3z]

oooorrrr.. you can slide the blue thing to the end of that rod and thread it through

[skimboley]

very very very...stupid..

[ub3r2008]

This is one of the reasons why topology is awesome.

[marzil]

that is clay, come on! do it with metal.

[vladimir0B]

This is a cool party trick! get some friends over or something and include this trick in the plan

[caddywhompus2000]

thats stupid. who carries a piece of clay around with them?

[bodinian]

You can not demonstrate this with clay, I'm not convinced until I see this done with metal

[guralnikownz]

i dont get it so if i try this with a metal 8 look it will do the same? Na

[Nowekian]

if you're strong enough to move metal! lol.

[billywongting]

or using some very soft metal

[alreadytaken334]

That's what she said.

[Muvlonion]

And this is why Graph theorists always treat the outer planer as a face, too!

[nelsyeung]

wow this is soooo clever!!!

[dangarbo10]

Great vid man ... I was trying to visualize this while reading a book and I was having a hard time. This saved the day!! 5 stars - keep up the good work.

[standup4urself98]

I don't know but I think he did a stopmotion? dont get me wrong but I still can't believe my eye's & YES I DO BELIVE in MAGIC!! heck I went 2 Las Vegas 2 see Lance Burton he's a magician to. Ithink that was cool 2!!!! =D

[bleeshpo]

I don't think it is magic or trickery. Please read the post below, I'm pretty sure it works fine. The hole with no stick just gets molded around - the stick never really goes through it.

[Th3H0wT0]

no it doenst.... watch it VERY carefully and you'll see it, dont wanna give the trick away though... just watch the left loop

[OusmandTakeover]

Well, of course it's stopmotion. It didn't move on its own.

[bleeshpo]

Mold the blue thing to the shape of a donut keeping the hole without the stick but making it small - like a donut with a wormhole. Take that little hole and stretch it around the stick until it is about to hit itself - like an exagerated smile. There's a little isthsmus left between the sides of the smile. Bend the clay a little around that isthsmus and you've got a stick through 2 holes. Right? No trick and no 3rd hole? This is the first time I've used the word "isthsmus".

[XxChrisAnthonyFanxX]

thats cool

[XcoreDK]

haha this is wax and computer animated trick

[damasta67420]

no he dosn't he moves it

[Leto85]

Hahaha, that was nice. In the beginning I didn't even know that is was made of clay. Otherwise I maybe could gues how to do it.

[TyYann]

Excellent!

[woopsedoo]

Wow that was fantasticly shit!

[Odood19]

sick! 5 stars!

[Techtoniq1]

da wurd die knete verändert, und geschnitten wie sau... 1*

[beratalbania]

easy...

[glf123456789]

coool

[Metagami]

at the top at 0:25 you transfered the outside of the object into a ring, and a ring into the outside of the object. Nicely done.

[romwell32]

Awesome combination of topology and stop motion animation!

[romwell32]

like, for math?

[hectorvrl]

LOL! nice XD

[brahman8908]

And also he didn't actually get the rod through the other hoop.

[brahman8908]

He built three holes. Thats stupid.

[lesliekwan80]

learn to count

[brahman8908]

it starts off with 2 holes in the dough. He then moves one hole to the center, now if you look at all sides for a brief moment you will clearly see three holes. Life is easy when you can count to three. Yes it is a cool trick, but in the first form there where 2 holes and in the last one he basically turned the whole thing spherical. Imagine putting a ball in the middle....How many ways could that ball escape? Go to the 25sec mark and you will see that it is three. YAY FOR BRAIN POWER........

[speedaddict2008]

nice stopmotion!

[dewinmoonl]

HahHA nicw!!!

[333chloe]

I love that movie that you made! I can't wait to see more.

[sidmjam]

awsome! again...
