That's the first fountain I've seen that I would like to have.

Water, sound, and video frame rates. Also, always include the sauce OP. https://youtu.be/uENITui5_jU

Whoa! That's rad.

this isnt actually what it looks like, it just looks like water spraying everywhere IRL.
Jus10Ed
So does that make them a water bender or an air bender?

Where is the video?

Where's the sauce!?

https://youtu.be/Q3oItpVa9fs here, have some music that is about affecting matter with sound.
SnipersAngel
I wasn't fully paying attention and thought 'i can't hear anything'
Tippster
...and Frame rate and shutter speed.
HenElt
Nope - it's real time. It's from a YouTube vid from a few years ago, where they even explained how it works... I'm sure you can find it :-)

Standing waves are pretty neat.

Have you seen it done with fire?
KnowerOfNothing
I have now!
51CorgisInABar
Right? That was my reaction
CheetahFart
But completely unrelated
VulpineEmpress
Drown the witch!
EmCeeMiNacion
At what sample rate?
Isthe4thtimethecharm
The witch controls water this one will have to burn.
robotbob123
She could extinguish the flames burning her. She's too powerful!
CrazinRican
But what if she floats?
VulpineEmpress
Couldn't find this online so I made a little OC for you:
Witch hunter logic...
jrsofty
Then she weighs the same as a duck!

And then we burn her!

BURN HER!!

Isn't it the cameras rolling shutter that causes this effect?
OCDdriver
Good question! A rolling shutter effect would be seen as a disjointed or disfigured stream.
DavidBrooker
No. But this is also a type of sampling error. Rolling shutter causes a different class of errors.
[deleted]
[deleted]
DavidBrooker
(As a rule, rolling shutter errors are still present when viewing a single still frame. Nyquist errors require a time-series.)
DavidBrooker
Right, but cameras can produce several types of errors. Nyquist errors, as above, rolling shutters, and many others. Both Nyquist errors 1/2
DavidBrooker
and rolling shutters are classes of sampling error, but they produce different effects. 2/2
Telruin
Mythbusters explain this. The gist of it, the hertz of the sound match the frame rate. In person it would look nothing like that.
spicypadthai
Do it really match?
MagikLight
So our eyes can't process the speed at which this happens?
ilikehornets
So uhh, the noise just vibrates the nozzle?
reux
Come on baby make it hertz so goooood
lostangle
Thanks! Was starting to get my hopes up for a science experiment. Would not work well with young kids.
shaun894
So.. is this what dogs see on old tvs?
DavidBrooker
This is called 'frequency folding' in sampling theory.
Ewanator
You da real mvp
pikasouras
@Telruin what about the shadow
Telruin
Light moves incredibly fast. If water is at the same point for every picture taken, it stands that the shadow would also be the same.
domenick91
So wait what would it look like in person?
justsaiyanit
.
YouMayFindThisMildlyInteresting
You'd see the wave, but it would be falling full speed from the faucet - not seemingly freezing in place.
capnh00kt
Mythbusters ended last season bro
NovaMakesMemes
I upvoted you, because haters are after ya bruh. Good luck on the next post.
CasuallyMasturbatingInPublic
So how is that relevant?
EternalSunshineOfTheSpotlessMind
Every show ends last season.
darearkin
So everything they did before that is now null and void?
scampbellucf
Nice, I'm bringing back the five second rule.
Telruin
I will try to give a longer explanation. Imagine a metronome, set to a 1 second interval. Then you take a picture once a second. 1/x
Telruin
Looking back the metronome would seem to be standing still. In the video the music is shaking the water, but it's still in the same 2/x
Telruin
location for every picture taken, as the camera takes 25 pictures pr second, and the music "shakes" 25 times a second. 3/x
Telruin
(The shadow is the same as light travel's incredibly fast, and if water is at the same spot, the shadow being made would also be the same)/4
lowesdriver1990
Why does the shadow sort of match?
[deleted]

helloworldtestingmic
This question is the reason we need better education and less pseudo science tv channels. Light speed = 300k km p/s
MeHoyMiBoi
The water probably does look like that in real life, but only for a split second at a time thus it wouldn't look like it in person. 1/
MeHoyMiBoi
But the camera captures only those split seconds it is in that position so you get a constant shape effect 2/2
IShouldBeStudyingRightNowInsteadOfBrowsingImgur
Exact same reason. Shadow matches frame rate of camera.
Win1forthegifer
Had the same thought
etherbunny41
It's the same principle as this: http://www.mirror.co.uk/news/weird-news/video-aeroplane-propellers-optical-illusion-2983200
Bhargo
obviously a glitch in the matrix
OCDdriver
Nope, that's due to 'rolling shutter'.

Why, why do you feel the need to summon him? Just cause he come here for points once a month?
BenjaminT247
guy said mythbusters explain this, so i am summoning a mythbuster
damnyuoautocorrect
No it was "mythbusters EXPLAINED this". It's done.
OCDdriver
When used with a strobe light it CAN be seen in real life. Very cool effect
MechAnon
If the frequency of the strobe is the same as the framerate of the video, so no different really...
OCDdriver
I just assumed that part was obvious.

Humans can only see 30fps, idiot. Xbox for life.
californiaqueensgetitdone
They've got a display for that at the Richmond Science Museum.
OCDdriver
Also at Science Museum Oklahoma (a fantastic tourist stop and next door to our amazing top rated zoo!)
Omen909
This could be considered a slight spoiler for a recent movie, but...
Omen909
Now You See Me 2 uses this effect as a minor plot point.
DuckTalesOohWooOoh
It's actually a big problem with florescent lights in shop environments. When bulbs flicker, moving saws can appear to stand still
Nyxkerrigan
Dont have all your lights on the same phase and make sure that atleast 2 phases are always on.
usersubbordercontrol
Hmm... sounds like an evil murder plan. Wire into the lights to flicker, to cause accidents... I wouldn't do that though
OCDdriver
Such a weird thing to see. does 50hz ballast fix the issue?
AGrammeIsBetterThanADamn
50hz ballast exacerbates the issue. You need an electronic 20khz ballast. Switches so fast, the lamp never stops glowing. So any T8 or T5.
OCDdriver
Informative!
leontheprofessional
The complexity of something so simple is amazing. Also I read specs on this stuff all the time dullest read ever.
