I’m sincerely puzzled by this. I was poking fun, not trying to be abusive. I’m very sorry if something I said (or the way I said it) offended you, but calling me names isn’t a super mature way to inform me that you don’t like to be teased on the internet.
The conversation was talking about a party. I don't really party and I don't really get drunk so for me, party was implying getting drunk. When I have a normal conversation with people, I try not to make passive-agressive comments and ask rhetorical questions, at least with strangers...
Okay, I admit touché. I was under the impression that a “hot toddy” was any hot drink made with liquor and sugar, but I’ve been operating in shameful ignorance lo these many years of my majority.
Still, you’ve never had a hot bourbon/rum/whiskey/brandy/vodka with honey, simple syrup, and spices and it shows!
Look at Mr Fancy over here with dedicated drinking glasses. I’m 39 and all my friends still use whatever is at hand to drink whatever beverage is available.
Right now I’m drinking white wine out of a high ball glass with ice cubes in it.
I haven’t drank in a while but when I used to have parties in our apartment people bought disposable cups to drink from, you wouldn’t just use glasses or mugs from the host.
Unless it’s a small group like 3-4 friends and you’re drinking wine or something, then ofc you’d bring out the wine glasses.
Hey! You too are trying to add some of your mean and useless contribution to the bashing thread. Thanks and I hope you break a knee right before Christmas .^
Maybe more of an "I'm bored at work" trick. If you find yourself at a party that would be livened up by stretching a rubber band around a coffee mug, it's probably about time to leave.
I mean, more and more I find myself going to and hosting parties where, instead of giant handles of booze, people bring a wine cooler and a diaper bag. Gotta keep the party tricks up with the times.
If your party is full of morons. This is like a kids puzzle. Like level one of one of those "3d chinese puzzles" you buy as a gift for someone you dont even know.
Ha I was doing a whole thing last night on that topic. I was actually making good strides towards understanding it too but it's so difficult but it's basically taking two points that aren't connected and attaching them via an unseen direction.
A bit like placing the two tips of a horseshoe on a piece of paper and picturing what those two points touching the paper would look like from a 2D perspective.
What's even more interesting however is that you can actually replicate this by wiring a circuit in 4D by connecting ends that do not physically touch on a board with wires creating a 4D style connection.
Imagine a tree growing over 20 years, but being able to see all 20 years of that tree at the same time. From seed, to sapling, to small tree, to big tree.
Typically this is the case for me but the explanation here helped a ton to lead me to the simple realization, just for this instance, that the rubber band isn't wrapped around the handles. It's wrapped around the cup!
I've been watching videos like this for over a decade, I've seen the gifs of how they pull electrical cords out from stuck places by feeding it through itself, I understand conceptually that you're effectively flipping the object inside out. Like here the rubber band isn't wrapped out the handles, it's wrapped around the entire cup. I understand that.
Topology is the study of shapes and spaces, specifically their properties that are invariant under stretching and squishing. So one trick to wrapping your head around topological properties is to stretch and squish something like play-doh until it looks more reasonable to you. If you flattened out the sides of the mug and shrank it so that you have basically just a loop with a bump on one side, maybe it's easier to see why the rubber band trick works.
Im fairly good at math back in the days, but could never do well with topology. with topology, some folks just seem to have a better innate mental map for it.
On this example in particular, just mentally invert what area you believe is the "inside" of the shape the rubber band makes. Instead of the small narrow section between the arms of the band, imagine the opposite area is the "inside" of the shape. Then you see that the rubber band can just slide off the cup in both directions.
Unfortunately, topology is one of those things that's a bit tricky to do much of without going full-on into proof-based abstract math. It's usually taught after a course in real analysis and abstract algebra so that concepts like the metric topology and fundamental group are digestible and relatable. These might not technically be required, but a level of comfort with proof-based math sort of is.
If you want to wrap your head around this trick and others like it, rather than just learning about topology in general, there are ways. Reposting my comment from elsewhere:

I think it deals with reading speed generally being faster reading one word at a time versus a sentence. I’m not sure if there’s been research on the comprehension with one vs. multiple words. Or maybe they’re trying to match the captions to the audio. Regardless, I agree with you
For most folks it looks like it's impossible to get the rubberband around the handle and the mug in that way without cutting and reattaching the rubberband or something. It's hard to visualize how flipping the rubberband over the cup results in this kind of configuration.
At first it looks like the handle was removed, the band wrapped around the mug from the handle base points, and then the handle replaced. Like if you just pinched a band wrapped around a cylinder with your fingers
Put the rubber band under the handle, pull tight around the mug till the ends meet, then wrap each end over the bottom and top of the mug respectively.
Theory of surfaces is really neat when you get a hang of it. My first professor when we got to topology was terrible and basically just pointed to equations and said "normal vector" this and "continuous surface" that. However, the next semester when we started with Green's theorem and all that I got a TA who knew our pain and was basically teaching the class instead of the bad professor because he was doing some research thing.
He deeply understood the material and it was so good to learn from him. I hope he got his PhD and kept on teaching. Here's to you De! You revealed to us the deep magic mystery of toroids and helixes and all that jazz, and I am a better person for it!
I think this is finally a better explanation to the video on how to untangle the electric cord without cutting it. I just still don't quite get it though.
I love topological tricks, they always seem so straight forward but my brain can never seem to grasp them until explained. Its like the "hold my beer" of magic.
This is why math people are literally insane, we should really be more greatful to them and phycisits, they usually die poor or alone because nobody understands them, on the other side we have toktoker idiots who can barely formulate a sentence bigger than 3 words who literally have cults and millions of followers.
This is NOT an optical illusion. Video creator is not using words good. This is just a real thing you can easily do that looks exactly like what it is.
Nice party trick actually.
If people take my mugs to drink at a party, I’m bonking them on the head with ‘em.
hot toddy enters the chat
A hot toddy party just makes me think of fuming hot columns of vomit.
Why? lol
The idea of getting drunk on hot drinks makes my stomach churn.
You realize it’s possible to drink without getting drunk, right?
You realize it's possible to communicate without being a disagreeable cocky prick, right?
I’m sincerely puzzled by this. I was poking fun, not trying to be abusive. I’m very sorry if something I said (or the way I said it) offended you, but calling me names isn’t a super mature way to inform me that you don’t like to be teased on the internet.
Sounds like you struck a nerve
Drink less and then it won’t:
a. Be weird to drink and not get drunk b. Not seem offensive when people have a normal conversation with you
The conversation was talking about a party. I don't really party and I don't really get drunk so for me, party was implying getting drunk. When I have a normal conversation with people, I try not to make passive-agressive comments and ask rhetorical questions, at least with strangers...
Looks like somebody has been drinking too much or too little.
But they haven’t been drinking exactly the right amount
My guy, I get jumping the bandwagon to get at me, but maybe, just maybe, do something more edifying with your day?
Holy hell, really came out of left field with your own cocky prickness for the most benign comments. You alright there sport?
Never tried glögg? It's delicious.
Eggnog with brandy is delicious.
It’s good with bourbon, also!
The only reason to drink a hot Toddy is if you're sick but still want to drink, in which case do that at home.
Or you have a wife named Ms Liz who makes great Hot Toddy’s
Oh, wow. You’ve never had a hot buttered rum and it shows!
Hot buttered rum and a hot toddy are two different drinks? Are you gonna accuse me of never having had an Irish coffee next?
Okay, I admit touché. I was under the impression that a “hot toddy” was any hot drink made with liquor and sugar, but I’ve been operating in shameful ignorance lo these many years of my majority.
Still, you’ve never had a hot bourbon/rum/whiskey/brandy/vodka with honey, simple syrup, and spices and it shows!
I do, when I'm sick and still want to drink.

Breakfast of the champions, a toast!
Cheers!
I like some order in my chaos.
Mulled wine
My friend has one that says "Yup, still gay!" and it's my dedicated drinking cup when at their place, doesn't matter if it's wine or coffee lol
Nice party trick actually.
You wouldn't do shit you'd sit there and deal with it then cry to yourself lol
Hey! You too are trying to add some of your mean and useless contribution to the bashing thread. Thanks and I hope you break a knee right before Christmas .^
im insured id get millions i hope so too
Impressive comeback, you’re very smart.
Thank you when your actually important stuff like that can happen
Oooof ouch, that hurts quite a lot.
you shouldve just replied with how you were gonna bonk me with one of your mugs instead of freaking out and messaging me 2 paragraphs lol
And he's too scared keeps messaging me lol
I knew if I waited long enough I'd get double text again
The comments have over 30 views. If anyone wants to see what this guy is messaging me just dm me I took a SS might make a weird post involving it idk
I still can't figure it out. It's unpossible.
Maybe more of an "I'm bored at work" trick. If you find yourself at a party that would be livened up by stretching a rubber band around a coffee mug, it's probably about time to leave.
I mean, more and more I find myself going to and hosting parties where, instead of giant handles of booze, people bring a wine cooler and a diaper bag. Gotta keep the party tricks up with the times.
Dude I'm mid 30s. I don't even go to parties anymore
I could imagine it as a Bar Bet.
"I bet you can't reproduce this" most likely.
Or possibly "bet you I can loop this rubber band around both handles…". (The wording would need to be very careful.)
If your party is full of morons. This is like a kids puzzle. Like level one of one of those "3d chinese puzzles" you buy as a gift for someone you dont even know.
nah, the cork fingers are clearly more impossible
/s
Topology is a process that my brain can never seem to comprehend.
It's like trying to wrap your head around a 4D object.
Literally a 3D object.
Yes, I know, but you forgot to consider that I'm dumb
Might as well be 10D
"10"?? What a fake lookin number. Think you can just put two numbers next to each other and get a real number?
5318008
See, I can do it too!

Thanks ... 👌 I know it was sentences in English. & I know I didn't understand any of it. 😉
It was ok but have you tried Harry Potter?
Imagine a tree growing over 20 years, but being able to see all 20 years of that tree at the same time. From seed, to sapling, to small tree, to big tree.
The trick is to wrap the 4D object around your head.
Stick RPG 2 endgame... Anyone? Just me?
Typically this is the case for me but the explanation here helped a ton to lead me to the simple realization, just for this instance, that the rubber band isn't wrapped around the handles. It's wrapped around the cup!
It’s not wrapping inside the handles, it’s wrapping on the outside of the cup
I've been watching videos like this for over a decade, I've seen the gifs of how they pull electrical cords out from stuck places by feeding it through itself, I understand conceptually that you're effectively flipping the object inside out. Like here the rubber band isn't wrapped out the handles, it's wrapped around the entire cup. I understand that.
My brain STILL can't comprehend it
Especially when there are a lot of VLANs to make it confusing.
I can easily grasp many things intellectually but topology has always made my head hurt.

That's a great idea! Im actually going to try this at some point. Thanks for the creative assistance!
Im fairly good at math back in the days, but could never do well with topology. with topology, some folks just seem to have a better innate mental map for it.
Came here to say this. I’ve seen so many explanations and my brain just can’t turn that corner.
Not a process it's just visualization
I have to admit, I saw this one and immediately thought “Oh yeah, you could just flip each side over the top and bottom to get it off.”
Check out the big brain on Brad!
Brett*
I DONT REMEMBER ASKIN YOU A GOD DAMN THING
What?
Say what again motherfucker!
You have unlocked the age-old feud between the Brett gang and the Brad gang. Bloodshed will follow.
...is that a threat?
Bitch, be cool!!
Yeah, not sure why, but this one seemed instantly obvious to me.
Same. I love these topology tricks
Yep, I'm really bad at visualizing stuff, topology etc but this one in particular was just instantly clear to me for some reason
Yeah me too, I was like this can’t be the fuckery I’m looking this video for
yeah, its not really an illusion. its still neat though.
Are there any good resources to get a mental grip on topography?
My poor aging brain yearns to know more about this bamboozlement.
I have a book about topology in the attic. Lemme go downstairs to the basement to get it for you.
Holy shit, a topology joke
It deserves a topology brain implosion gif
goes upstairs
"Damn, I'm in the garage."
try this standup maths video.
On this example in particular, just mentally invert what area you believe is the "inside" of the shape the rubber band makes. Instead of the small narrow section between the arms of the band, imagine the opposite area is the "inside" of the shape. Then you see that the rubber band can just slide off the cup in both directions.
I'm saving this comment for when I have more brain cells available to think it through lol, thank you

Once you know how to read contour lines topography is pretty easy.
Off topic but god I can't stand these one word at a time captions
I
agree
with
this
complaint
Topologically, this is just one sentence at one time.
If nothing else it needs to be closer to the subject matter - can't read them while also seeing what's going on.
Personally, if covering up the captions with my finger blocks the subject matter, I won't watch the video.
I think it deals with reading speed generally being faster reading one word at a time versus a sentence. I’m not sure if there’s been research on the comprehension with one vs. multiple words. Or maybe they’re trying to match the captions to the audio. Regardless, I agree with you

Nice! I am a grown ass mid thirties guy but I am gonna go to my mum’s kitchen, do this to all the cups and drive her crazy with this trick now!
As a late 40s bloke, I'm about to go do the same to bamboozle the kids
That is not what "optical illusion" means, if anything, it's a topological illusion. An optical illusion is visual, not physical.
Topology joke: What's the difference between a mug and a donut? Nothing.
Same as the difference between a man and a donut
But people have 7 holes.
VSauce lied to me
Pretty sure only one goes all the way through lol
Cool trick, but not really an optical illusion.
bro keeps saying "optical illusion"
i don't think he knows what that term means
I... don't get it. It's a rubberband around a mug handle. What's the black magic fuckery at play?
Edit because you have to say this on reddit, but, I am being genuine. Not being some "big fucking whoop!" asshole.
Yeah, it's not an optical illusion, what you are seeing is what is happening, it's just a neat way to do it.

How people continue to get the idea that posts which show exactly how something is done belong here is the real blackmagicfuckery.

This is what usually happens to my necklaces in my drawer and it is equally as confusing as to where to begin to unravel them as this mug.
There are days that I feel like I understand quantum mechanics better than I understand topology.
Someone help me, I know this trick every time I see it, but I need to look it up to actually solve it, what kind of thought process does this require?
This isn't magic or an optical illusion.

Why does he keep calling it an optical illusion tho?
This will somehow explain faster than light travel in the future.

"Honey, I need a rubber band and a coffee cup, right now"
Honey: "What freaky s$#@ did you find on the internet now?"
Uh no. Not magic at all. My 10yo nephew even knew how this was done.
This is NOT an optical illusion. Video creator is not using words good. This is just a real thing you can easily do that looks exactly like what it is.
It's a mental illusion.
I understand. But in the meantime, I don't.
Did he say, "topological Harvard" or "topological marvel"? Because it sounds like he said "harvel"
it hurts my brain

This is not an optical illusion
I feel dumb that I didnt think about the possibility of wrapping it around the bottom of the mug. Seems obvious in hindsight.
Saving this and forgot about it
I thought I was smart. I watched this. I still can’t understand it. I feel dumb.
MAGNETS.
I guess we’ll never know how this black magic fuckery was done.
All I see is a rubber band around a donut.
This counts as moving from 2 dimension to 3 dimension right?
Very impressive!!
Why’s that guy putting rubber bands on donuts
Ah, you kids and your topography....
We need more tutorials for this type of fuckery
thanks- I hated this!!
I love when the black magic is explained, in detail, in the video. Really fits in this sub.
Worst post ever
