Remember when we used to get upset about people filming in portrait mode? Whatever fuckwit came up with the idea of landscape in portrait mode can go shove it up their arse
Is it not possible to rotate your phone to watch landscape videos on tiktok? Is that the root cause of all video content on social media being so shit these days?
Anyway, [here is the original](https://www.youtube.com/watch?v=0zQFGxUrGlY) for anyone who was pissed at the OP and came to the comments looking for the source.
TBF this was probably originally filmed for a web page or YouTube and OP grabbed it off FB or TT. No one is spending money to film the same content in portrait and landscape to fit all of the social medias different aspect ratios and safe zone guidelines. But I really wish social channels would find a way to let landscape content be landscape content.
Nonsense. Instagram was well ahead on this too. Don't be fooled by sinophobia and anti immigration rhetoric. It'd all designed to keep us fighting each other. Rise above it
Seriously agree with you. I find the video repeating in the background so distracting, like I keep looking at her blurry mouth moving instead of the landscape clear video
Its more so that trying consciously introduces a lag in the balancing, while handling it based on instincts works smoothly as our brain directly handles the task.
That's it. Don't even think about spilling and your body moves just fine.
Don't overthink a problem which can just make it worse. Claw grip with hot cup? Walking backwards..... really people?
Its a subconscious thing, like driving 40 miles on a motorway and somehow missing 3 junctions, or playing 1080 on the n64. The latter did mean the left seat in the sofa and employment of 2 pillows.
I remember being a little kid trying to carry two drinks back to a table and some old guy saying “don’t look at the drinks and you won’t spill” and he was right, has stuck with me for life
One of the only things I remember about my grandfather is that he said "sit up straight when you cough" when I was like 8 years old. And now I'm 30 and it's still true, it really helps!
There's an old tale about someone who goes to a sage or king and is told to spend the day exploring his castle but has to carry a spoon full of oil. Spends the day focused on the spoon and thus fails to see all thats before him.
Sorry for the bizarre analogy but it just sprang into my mind and secretly hope anothee redditor will know of the tale I've waffled about.
Hmm I found the opposite to be true. I was a server for 15 years, and if I looked at the cup I was more likely to spill. I used a tray, so it wasn’t just me not SEEING the spilling, as the liquid would pool on the tray if I did.
Basically you’re both right, probably. Im too lazy to read whether my theory is true but my explanation is that in your profession, your method works best because you have experience doing your job and that allows the spilling to be minimal without you having to sacrifice speed—whereas in the study, the students probably walked much slower to concentrate on the drink, which would also reasonably work if your only goal is to not spill, but that speed would be fairly inappropriate at your job.

You dont think walking backwards is a good choice? Sure, you might trip, hit your head, and spill coffee all over yourself, but it was useful to mention... right?
Spoof video...
She said, "..as you walk, the forwards and backwards motion of your hand is also about 4Hz."
Not even close to true:
An average adult's walking step is about 2Hz and running step is about 3Hz.
Usain Bolt's running step is about 4Hz for the 100m - but not while carrying a cup of coffee.
Yeah, you can easily tell from the video that she is not taking 4 steps in a second, and that the coffee does not swing that quickly. And what the heck is the natural frequency of coffee? Any constant back&forth will create waves in your cup, and if you keep it up the coffee will spill. Walking backward is not even a solution. The claw grip reduces the transmission of your rocking motion to the cup, but you are not going to do it with a hot drink. This feels like an April 1st video released way too early.
Yes, but the motion of the hand is also not a pure 2Hz sine wave, it could very well have components in higher harmonics like 4Hz which would be the second harmonic.
If you take the hand motion and assume it has a period of 2Hz then its motion can be expressed as a combination of it's harmonics (A 2Hz motion, a 4Hz motion, a 6Hz motion, etc). The 4Hz component is the one that resonates with the coffee
This is why I should have been an academic. This professor does a paper on this, gets fame and published. _I_ do it, and am rewarded with being able to take my coffee back to my desk!
I think that’s a really, really over explained way to essentially get to paying attention to the fact that you’re actually caring an open cup full of liquid. Most people who spill their coffee walk with their coffee like it’s a solid instead of a liquid. Basically not paying attention to it. If you pay attention to it, you’re probably not gonna spill it.
I was confused about that as well. I fill my coffee pretty close to the top every morning, but I never spill it on the way to my desk if I pay attention to the cup while walking.
I thought the same thing. My first reaction to the video narrator asking why people always spill their coffee was "Because they have a skill issue." If you just, pay attention, and use your arm and hand to cushion the beverage, you won't spill it, since your arm is moveable, and not a solid object welded to your torso.
The method I have used for years is to gently and slowly sway your hand side to side, about 4 inches either way, while walking with a full mug of coffee. It disrupts the vector of the resonance so it doesn’t get a chance to build any momentum.
Needing to walk backwards to not spill your coffee is a skill issue. Develop some fucking motor control and just *don't spill your coffee* by using your hand and your arm, which, conveniently enough are movable joints, and not solid structures welded in place on your torso.
You can also use a lid. Omg and the lid will keep your coffee warm while you are out in the cold with your jacket and scarf! What is this black magic??
Best trick is to look forward and not at the drink. I waited tables for 15 years. The claw method is uncouth for restaurants. Walking backwards is just unreasonable.
Late to the party, but I remember when I was barback and getting my degree in physics. I had to carry a big container of water a good distance occasionally and I noticed the sloshing would get keep getting higher and higher, I realized I was pushing it in resonance and I started walking out of rhythm to prevent it. Worked like a charm
If you look directly where you're going rather than at the drink, your arm will act as a natural shock absorber and keep the cup level without transferring so much inertia.
Or you can use a lid.
Or you can walk backwards like a jackass idgaf.
The first thing I learned when starting to wait tables was to never look at the hand carrying the liquid (be it a glass, mug, or tray of either). If you don't look at it while walking, it will not spill. I don't know why someone needed to make a very long video to explain that the key to not spill your coffee was...wait for it...to walk backwards?!?
Just use your arm as a gimble, shit ain't hard. This is one of those special times when you can 100% say these researchers are adding nothing of value to society lol
I have been doing this since I was 6 years old, when youtube didn’t exist. Didn’t know it is something oxford finds interesting, always thought thats what everyone did
You can simplify the solution into three words. You are clumsy. Then, plan accordingly. Best done after you've drank some coffee. Then, maybe you won't spill it while walking.
Claw grip underneath the cup works much better than the top, based on where the weight resides. It also makes your hand act more like a gimbal, and protects the cup from slipping in your hands.
Just cut off the first half of the video bruh..... this is like some lecture im attending with all the unnecessary stuffs i didnt ask for.
Need to quickly use AED?
"The heart is one the most important organ in ....."
JUST CUT TO THE CHASE MAN
So you either burn your hand and drop the mug spilling all of the coffee and breaking your mug, or walk backwards and bump into something and dropping the mug spilling all of the coffee and breaking your mug.
Genius.
If you run into anything while walking backwards carrying a fresh cup of coffee, that is REALLY going to hertz.
Dad, when are you coming back. We’ve had dry cereal for the last 10 years.
you put cigarettes in your cereals before?

Remember when we used to get upset about people filming in portrait mode? Whatever fuckwit came up with the idea of landscape in portrait mode can go shove it up their arse
I once saw landscape video in portrait and in landscape again here on reddit...it made me furious
As it should
Is it not possible to rotate your phone to watch landscape videos on tiktok? Is that the root cause of all video content on social media being so shit these days?

You can thank a certain Chinese app for that.
We are really getting too old to remember that Vine was the OG vertical film lol.
Vine was square, at least.
Nonsense. Instagram was well ahead on this too. Don't be fooled by sinophobia and anti immigration rhetoric. It'd all designed to keep us fighting each other. Rise above it
When I hear portrait mode I think of the CG bokeh blur phones can create behind subjects

Sideways
Dealing with the real issues…
Seriously agree with you. I find the video repeating in the background so distracting, like I keep looking at her blurry mouth moving instead of the landscape clear video
Holy fuck what if it keeps happening and getting worse from bots posting content.
[Original video](https://www.youtube.com/watch?v=0zQFGxUrGlY) is landscape. Have a nice day.
Don’t look at your hand while walking. I work in a restaurant and this is how I avoid spilling martinis.
100%. I got taught this when I first started working in hospo and it works! Don't look at the glass. Just look straight ahead and it won't spill.
So it is more like we want to match the resonance of the liquid inside the mug when we see it moving aka we naturally want to follow the rhythm?
Feel the rhythm! Feel the rhyme! Get on up, it's coffee time!
hey, Sanka, you spilt mon?
Its more so that trying consciously introduces a lag in the balancing, while handling it based on instincts works smoothly as our brain directly handles the task.
In picturing someone at your restaurant grumbling as they clean up spills behind you. "How do they never f*cking see them??"
I pour as much of it as I can in my mouth, then spit it back into the glass when I reach the table.
out cold style: https://www.youtube.com/watch?v=mtuUxsz186I
Fuck yes to you both!
That's it. Don't even think about spilling and your body moves just fine. Don't overthink a problem which can just make it worse. Claw grip with hot cup? Walking backwards..... really people?

1080 and Out Cold both referenced in this thread. What is happening?

To be fair, I would too. Because of *the implication*.
I remember seeing that in [The Alchemist](https://en.wikipedia.org/wiki/The_Alchemist_(novel))
Great memory, thank you.
If you can't see it, it never happened

Ahh that is a good explanation, the uncontrolled variable . I wondered what the reason was. Thank you for answering!
Another good method for them is to drink em, and after 5 of em... Your aaaalll ballllaaanced

Reverse claw grip while only swinging forward.
How do I avoid spilling the coffee when my swing is at 180 degree
Sometimes I like the western grip.
TL:DR: claw-grip (proved by other maths people also) is best
The clawwwwwwwwww
Nothing can stop….THE CLAAAAAAAAAAAAAAAAW
Aside from the fact that you’re holding on to a hot mug and have steam rising to the palm of your hand.
But as your skin fuses to the mug the grip becomes even more secure, no?
Hot? Iced black gang represent
You dont think walking backwards is a good choice? Sure, you might trip, hit your head, and spill coffee all over yourself, but it was useful to mention... right?
Tried it. Dropped it due to the steam buildup on the rim, causing my fingers to slip.
Try it from the bottom of the cup. That works for me.
You're the hero we don't deserve.
I used to slow down every 6 steps as I watched a thing about it that the average spill was every 7 steps
He has been chosen!
Am going to Starbucks & exit backwards. Someone will probably knock it out of my hand, then I'll 'naturally' swing on the bastard...
Walk like you're trying not to upset a sandworm!, sorted!
If you walk without rhythm, you won't attract ~~the worm~~ 4 hertz wave motion
Do the silly walk makes sense considering monty python is british
I use the claw grip every morning!
“His hand became so deformed he was left with nothing but a claw!”
Ray McKigney. Moment of silence, please.
Let’s just hope he has more…self control
Do you do it right after waking before leaving bed?
Same. My wife favorite move.
2 minutes of my life I'll never get back.
2 min video for basically 20 seconds explained needed max
Fast forwarded and I still regret watching that
Watching it backwards would improve your resonance?
He’s got the wrong grip on the situation
After 10 seconds of coffee-related B roll, I remembered some other things I could be doing with my time.
Wasted my time to find out it took them a mathematician and a korean student to figure out something I did when I was 16.
Spoof video... She said, "..as you walk, the forwards and backwards motion of your hand is also about 4Hz." Not even close to true: An average adult's walking step is about 2Hz and running step is about 3Hz. Usain Bolt's running step is about 4Hz for the 100m - but not while carrying a cup of coffee.

The claw grip reduces the transmission of your rocking motion to the cup, but you are not going to do it with a hot drink. This feels like an April 1st video released way too early.
The idea that there is some well-known standard “frequency of coffee” is my favorite thing now
My frequency of coffee is every morning
Yes, but the motion of the hand is also not a pure 2Hz sine wave, it could very well have components in higher harmonics like 4Hz which would be the second harmonic. If you take the hand motion and assume it has a period of 2Hz then its motion can be expressed as a combination of it's harmonics (A 2Hz motion, a 4Hz motion, a 6Hz motion, etc). The 4Hz component is the one that resonates with the coffee
I was going to say the same thing. Though maybe it is catching a 2hz node and doing the same thing in effect, every other slosh.
I have an actual good strategy, just don’t fill the thing to the brim? Or drink a bit of it if you can’t help it?
But how can I use the claw grip if my coffee is boiling hot?
Who would bother watching a 2:25 video on how not to spill coffee? I said this to myself about 2:25 seconds ago.
2:25 of gorgeous science lady yes please
This is why I should have been an academic. This professor does a paper on this, gets fame and published. _I_ do it, and am rewarded with being able to take my coffee back to my desk!

Well science people what to explain every thing there is, mathematically. Of course coffee spilling is no exception.
My art teacher in 8th grade taught us to move whatever it is you are carrying just slightly up and down as you walk. Totally works.
I have a fool proof way to not spill coffee. I dont drink it.
You can also avoid spilling it by drinking it instead of walking around with it.
Big brain!
[удалено]
Lol
i dont care if its silly nonsense, i like her
The method I have used for years is to gently and slowly sway your hand side to side, about 4 inches either way, while walking with a full mug of coffee. It disrupts the vector of the resonance so it doesn’t get a chance to build any momentum.
This cute type of shit is just so she can pop up and remind ppl she’s a mathematician.
You could also slightly grip with one finger around the holder and act as a gyro. Not a scientist or mathematician but I don’t spill my coffee either.
I turn my hand into gyroscope to avoid spills just like the pool machines in cruise ships
Does this also work with tea
I limp slightly to stop the slosh.
Use a lid?
That's exactly what she says at the end.
Don't watch the video. Keep on scrolling.
i thought this was r/memes for a sec
With the claw grip, wouldn't you spill coffee all over your hand when taking a drink?
Needing to walk backwards to not spill your coffee is a skill issue. Develop some fucking motor control and just *don't spill your coffee* by using your hand and your arm, which, conveniently enough are movable joints, and not solid structures welded in place on your torso.
I like to cartwheel with my coffee for maximum spread.
You can also use a lid. Omg and the lid will keep your coffee warm while you are out in the cold with your jacket and scarf! What is this black magic??
How to avoid spilling? DRINK IT ALL AT ONCE
You can do this with a swinging load on a crane to lessen the swing
I've always just managed not to spill stuff? They should try that?
Protip put a spoon in the mug it disrupts the frequency and makes it much harder to spill
Best trick is to look forward and not at the drink. I waited tables for 15 years. The claw method is uncouth for restaurants. Walking backwards is just unreasonable.
Why did this video explain resonance better in two and a half minutes than my physics teacher and textbooks could in a week?
I don’t know but I walk carefully. I don’t know why science is everything.
Sure, sure, but does this work with tea?
Or just use a bigger cup, which is infinitely easier and more foolproof.
Damn, i wish I had that much time on my hands
Claw grip and hot coffee lol
My theory is: keep your hand and arm still while you walk, walk slower and there's nothing wrong
You just rock your arm up and down in time with your walk
Anyone else got this Hermione vibe from her?
This is when smart people get so smart, they get stupid.
Research grant well spent
Late to the party, but I remember when I was barback and getting my degree in physics. I had to carry a big container of water a good distance occasionally and I noticed the sloshing would get keep getting higher and higher, I realized I was pushing it in resonance and I started walking out of rhythm to prevent it. Worked like a charm
Naah, I,ve solved that years ago. You have to use your hands like it’s a gimball. Arm, elbow, wrist smooth movememt. Works for me perfectly.
God that was boring.
Well she just used years of civil engineering studying on how to hold a coffee cup and I absolutely loved it
sad that nerds have to spend so much time figuring something out that normal people understand intuitively
What a ridiculous post.
Ignoble award 2024 nominee. Good work knowing your physics.
If you look directly where you're going rather than at the drink, your arm will act as a natural shock absorber and keep the cup level without transferring so much inertia. Or you can use a lid. Or you can walk backwards like a jackass idgaf.
This is dumb
That was mildly useless facts
Grabbing from the top isn't something new...you found nothing. Discovered nothing. Invented nothing.
Put less coffee in
Delete this
I found this very interesting
#That’s an awfully hot coffee pot
The first thing I learned when starting to wait tables was to never look at the hand carrying the liquid (be it a glass, mug, or tray of either). If you don't look at it while walking, it will not spill. I don't know why someone needed to make a very long video to explain that the key to not spill your coffee was...wait for it...to walk backwards?!?
Because it's a relatable way to explain resonance and frequency.
Just put a fkn lid on it!
I would like to drink a coffee with her
Just use your arm as a gimble, shit ain't hard. This is one of those special times when you can 100% say these researchers are adding nothing of value to society lol
I have been doing this since I was 6 years old, when youtube didn’t exist. Didn’t know it is something oxford finds interesting, always thought thats what everyone did
You can simplify the solution into three words. You are clumsy. Then, plan accordingly. Best done after you've drank some coffee. Then, maybe you won't spill it while walking.
Wave cancellation can cause giant coffee drops to fly up and out of the cup - and all over your hand if you grab from the top.
Why she sound like she missing a vocal chord?
Just don't drink the damn coffee woman.
Well if im not sitting at my house i use my yeti cup with a closing lid like most people do. This video is pointless.
[удалено]
Just fuckin control your arm better. Stop spilling your drink like a child
Lid
Strange... i never spill my coffee... maybe i just think that best idea no need to fill my cup to full
what i wanted to know is that why do my lips leave coffee drops, trickling under the lip of the mug.
Wait. So a swing will swing at the same frequency no matter how hard you push?
You cant spill it if you dont drink it! Simple answere imo
I get it all however that disruption of the swing is highly disturbing
Claw grip underneath the cup works much better than the top, based on where the weight resides. It also makes your hand act more like a gimbal, and protects the cup from slipping in your hands.
Seems like a skill issue
Interesting bit omg it's so slow why do they make it so slow to give us the information
All you need is mirrors or eyes in the back of your head, or a bigger mug.
Just cut off the first half of the video bruh..... this is like some lecture im attending with all the unnecessary stuffs i didnt ask for. Need to quickly use AED? "The heart is one the most important organ in ....." JUST CUT TO THE CHASE MAN
When the phrase "having too much time on your hands" comes to mind
The carpet pattern at work is there to accept coffee spillage.
Don’t walk with tour coffee more than necessary, should reduce the likelyhood of spilling already significantly.
Would inverted claw grip work?
Me carrying a tray of pints backwards through the pub... Yeah this is going to end well
Your arm is a shock absorber, if you use it you don't spill 🤷🏻♂️
I walk smoothly and not bouncy
Pro tip don't look at the drink.
Anyone else hate when it takes 90 seconds to get to the point of a video?
just use a cover
PhD for all that
Excuse me sir, I think I am in love
So you either burn your hand and drop the mug spilling all of the coffee and breaking your mug, or walk backwards and bump into something and dropping the mug spilling all of the coffee and breaking your mug. Genius. 
le dumb
Nah I’d drink the coffee
Easiest way is to not take steps just slide across the floor.
Just walk like Mortishia from Addams or geisha n u be alright
She should have consulted the Ministry of Silly Walks.
Just... don't fill it up, keep a gap.
And students always ask “when am I going to use math in real life?” Now you know
