I went into the Video like: wait what? And then: oh yeah, that makes sence

You can also just not fill it to the brim... the dune equivalent would be to not go anywhere near that planet. [Thank y'all for this multi-thousand Like morale boosts from this very incidental throw-away comment, and thank you the many funny and thought-provoking replies.]

"Walk without rhythm and you wont disturb the worm" -Terraria dunetreader boots

A fun story related to this is when building the shinkansen the japanese engineers had issues with getting the train faster because their overhead wires started to oscillate damaging themselfs and the train. At the same time the french TGV was faster the shinkansen so the engineers went over to france to find out what they did differently. Turns out the french werent too precise when putting down the posts for the cables and had some odd meter differences between them while the japanese worked to centi and millimetre tollerances. Due to this the resonance frequency of the wires on the french side was not constant and the train could go faster

Doesn't for weapon of choice. "If you walk without rythm, you won't, spill, your cofee."

"Sir did you irish that coffee you walking funny"

I remember Cambridge did a whole study on this, basically was a normal walk over 6 paces it starts to slosh 😂

Now i cant stop imagining going to a cafe and the barista does the sandwalk every time they go hand out a coffee

you can point the coffee slightly in the direction of where you're going. slightly! the faster you go the more tilted you make it. its like that swivel tray thing

Mocad'Dib, Coffeatz Haderach, he who takes the coffee

You don't know how beneficial this information to a waiter

He's very right, I've been walking without rhythm for days now and I haven't attracted a single sandworm.

There's a story where constant simultaneous footsteps from an army marching over a bridge destroyed the bridge which works kinda like this

When you realize your arm doesn't have to move the same way as your body when walking: Now my arm just has a Gyroscope..

I discovered this effect as a child without knowing about any physics... Really cool

Gonna start crip walking when I’m holding a coffee

If you claw grip the cup from above (if the cup's not too hot) and let your wrist sway slightly, the sway will cancel out with the waves and often never spill a drop even while walking and turning fast

Never rly thought about how to avoid mechanical resonance with my coffee before but thats rly smart

"Why are you walking like Jack Sparrow?" "Shh, you'll spill my coffee"

Instruction unclear…. Summoned giant sand worm at the office

Wait, so you telling me, to not spill my coffee, I must make peace with Caffa-i-Khaliq.

Or walk normaly and rock your hand back and forth at a 1/3 pace to every fifth step. It’s the same level of harmony practice by middle school bands.

My favorite part of that movie was when they told them not to walk with a rhythm and their special sand walk has a very distinct rhythm.

As a young child I burned myself really bad when carrying a hot cup of coffee across a room. I was scared to cary hot items for a long time and learned to do this by watching carefully as I got older.

Depending when and how you spill your coffee, both will also feel like the same thing.

This has the same energy as using a cup of water to learn how to drift a car

So that’s how I never spill a drink when absolutely BLASTED

Funny way of saying just don't walk like an angry cartoon character

As a caffeine addict, I shall heed your advice next time I'm running an errand with coffee in my hand

This is also why British soldiers "break step" over bridges. In 1831, a bridge collapsed under them, partially because their footsteps matched the resonant frequency of the bridge.

Note to self if I randomly teleport to the dune universe hold a cup of coffee

That sandwalk is a cool little detail that made the movie super interesting, as well as many other things

Instructions unclear, my top half keeps my drink stable when walking

sandworms : ok now we know those are humans too

Walking up stairs with a cup of coffee is a good way to find out what hating being alive feels like if someone doesn’t already

I never realised I had been sand walking my whole life

It's so cool how this absurd opening just makes sense in a matter of seconds

Always gonna do sand walk when getting coffee for my entire life from now on

I figured this out intuitively long before I saw this video. Its very interesting how we can utilize things that we have figured out through trial and error without knowing the underlying reasons as to why something works.

"That's why I drink coffee while walking on the desert" ah explanation😂

Shoutout to dune for inventing physics

Me : **spills coffee** Also me : "It's a dune reference, u wouldn't get it"

that's why i just watch my cup and change my steps according to the waves

I like this being a sort of training for avoiding fantasy/sci-fi creatures. like how they had princesses balance books on their head to keep a straight posture, people in another world would try not to spill something while walking to keep from waking beasts

i like to imagine that this is exactly how Herbert came up with the sandwalk. "hey, if i pace my walk weirdly, my coffee won't spill.... wait... oh my god!"

A bottle with a screw on cap is also a good container for longer runs

"that's cool story bro, but you gonna pay that coffee"

*Me who took marching band never having to worry about this*

This is literally how i carry stacks of plates and bowls

I've noticed this, mainly in the context that my right arm is a MUCH more stable gyroscope than my left.

Wow what a throwback to continuous time systems imo

Really interesting take on connecting Dune and a cup of coffee 😅 and above all, it makes sense 😂

Stillgar will scream "Lisan Al-Gaib!" three days straight.

missed opportunity to call it the dune-iverse

That’s a real fun way of explaining it

Aight when I see the sand worm I should bring a coffe

I found that I moved by cup up and down while walking, it somehow prevented this issue.

Also a small tip: if you sneeze while holding a full cup combine your uncontrollable movements with an upward movement from your cup, so the downward pressure outmatches the side to side movements

that would’ve been sick if they actually used that in the film to help them walk carefully

Legend had it, if you walk with a full cup, and don't spill a single drop, Stilgar till appear and shout "LISAN AL GHAIB"

Wow...if they teach like this in school....I would have never failed

Yeah but everyone in the office will think you're mad

Oh that's why I always fail to drink water while walking

i am a recent barista and this has been a recurring issue for me with americanos specifically. gotta sandwalk, thank you

It's quite interesting. The oscillating frequency of liquid inside a cup is about 2 Hz. And it just so happens that the average number of steps a person takes per second is also 2 steps per second. This means you will encourage the cup to spill if you walk at a normal pace. There are 3 ways to overcome this. 1. Get a different-sized/shaped cup 2. Walk in an irregular pattern 3. walk slightly slower than you normally would

this also works for the liquid in my head when i get drunk.

Another less awkward way to do this that works well is to move the mug in smallish circles.

For me, I just run on my tippy toes but slowly accelerate so it doesn’t spill. The bounce from each step is does effect alot

He's just Vsauce but with more hairs

Making my tea is a dune reference

So thats why the Fremen like spice coffee so much, they know how to drink it properly

I thought this was fire department coffee lol, atleast I learned something new

buddy I'm addicted to coffee, i found this out on my own through trial and error

You could attach it to a string and quickly swing it in a circle

As a person who can levitate instead of walking, i think this is an absolute win

I just roll-step like back in marching band.

Holy sh- i cant explain how helpful this is for me

did I finally find the reason why I can't seem to spill my drinks compared to everyone else, it's my fucked up walking all along???

You also can just not move your hand while walking it helps btw 😂

If you walk without looking at the coffee cup, it also greatly reduces spillage

Most fluids interact with how sudden your movements are. If it's not a hot substance like coffee, you can hold the cup from the top, moving the center of gravity higher so that you won't spill as easy.

You can also swing it in a loop with a straight arm. With enough velocity it should stay in the cup.

The part where the coffee spills hurt my soul

Yeah being a busboy taught me to not spill all 6 coffees I was carrying in one hand

I did this and I certainly attracted the office sandworm

Great, thanks for the idea. My intern is gonna have a busy day of practice tomorrow

I feel like we all do this unconsciously when carrying mugs of coffee

The way i walk with liquids is by basically keeping my arm as gyrocopic-y as possible

You could also hold the cup from the top, and keep your wrist loose to turn your arm into a gimbal

Brb gonna start cripwalking around the office from now on.

Going to try tbis now. Thank you!

Alternatively, dash across the room while angling the cup then flip the angle while stopping so nothing spills.

Never thought I’d see a guy that looks like Will Ferrell and James Hetfield had a child

You can also walk normally if you move the coffee cup in a circular motion as you walk.

After marching band I didn't have to worry about that. We have to march in a way that our upper body doesn't bounce as to not make the sound shaky. So with proper technique, we could probably march without the coffee even sloshing.

Information I didn’t want but we all needed

simplistically brilliant

A college friend taught me to mentally hum a waltz. It works!

remember guys next time you go to the desert make a cofeee first

When I was young I learned to walk in a way that was super stable, even walking fast my head wouldn’t bob around and whatnot, I still can and i call it “hover walking” I’m not really sure how to describe how to do it 😅
