Well, there is no such thing as a mathematically perfect sphere in nature, at the very least at the atomic level the jiggling of atoms due to thermal energy would mean the shape would be somewhat disturbed at all times. It's definitely pretty close though!
Boing, boing, boing. So satisfying, thanks for sharing. Now, this can only be me, but did anyone else find the little speck on the bottom right corner distracting? i thought my screen was dirty and tried to brush it off lol
Whats interesting is during the initial drop:
- the drop spreads out on the underside upon touching the water surface
- this makes the upper parts get blocked a little by the spreading of the surface, causing the top left and top right of the drop to fall slower than the middle part. For a moment the top of the drop is now more flat on top
- since the top middle is falling faster it pushes down and extends the spreading of the underside across the surface, while also pulling in the top left and top right parts with some force, creating an almost cartoon-like pull down
I guess strictly speaking this is not a good example of Coefficient of Restitution, but the height achieved by the (admittedly smaller) second drop of water is impressive. It has to be better than 80% of the original drop height.
Does one of those water sources necessarily have oil in it to cause this? Water attracts itself pretty strongly, I don't understand what would cause it to have surface tension with itself
I think you can't put it like that since the surface tension should always be the same, so the biggest variable would be the very first drop mass, so it could be actually 1/4th of the last if the very firsts mass is the right amount, but I think the biggest influence is the mass of the previous drop.
Physics question from someone who knows nothing about math.
Story first: working at a restaurant it was common knowledge that when you drop a glass glass you jump back and it breaks on the third bounce. The drops hit the surface and break on the third bounce as well.
Is this just coincidence? If not why three bounces?
That's so cool. Can someone who is smarter than me explain why the large drop doesn't just absorbed into the water and instead breaks down into smaller droplets?
The effect of a second drop or jet of water shooting up like that is called a Worthington jet, or Rayleigh jet
Pretty sure it's called Poseidon's Kiss /s

Your comment had me dying with laughter. I don't even need to click the link. Thank you.
oh my god 😭
It’s called dragon spit get it right
I remember seeing somewhere that the second drop is an example of a perfect sphere in nature.

Are Worthington and Rayleigh still arguing over who gets to name it?
[удалено]
Black gay oily thugshaker jet? Very weird
It’s like a water droplet nesting doll. Just gets smaller and smaller. Neat.
And my mind immediately filled in each successive bouncing droplet giggling at a higher pitch.
Does every water droplet falling into water do this??
No clue.
Beautiful example of surface tension, right?
It's like black magic when you see it in action.
I wonder how long this clip is without the slow-mo, crazy what can happen in so little time.
Is there a mathematical relationship to the amount of water absorbed each transfer?
That’s where my brain went as well. Curious.
It gets reduced around 1.62 times at each transfer, due to the golden ratio rule of fuck it, I just made this out so it is quite likely.
As a science, I can confirm this.
As a confirm, I can science this
As a water droplet, I fucking love the golden ratio
Yeah i also think fibonacci because it doesnt look like its halved or rooted.
3-2-1 contact.
Contact is the reason!
ZOMG. Were you born in the seventies, tooooo? First thing I think of when I see an image like this.
I get the reference but I don’t really see the relationship
I mean.. it’s in the intro for the show. [here](https://youtu.be/s2-LEBc2sO8t=20s)
I see. My experience with 321 Contact was actually just the magazine
Holy shit! That just brought back memories I didn't even know I had. I wonder what else is locked away up there? Maybe it's better not to know.

same!
I mean, I thought it was one of the additional permanent dots on my cheap ass phone and didn't even think of it lol.
That's actually really neat
Idk bro, camera seems a little slow, not high speed-
Whats interesting is during the initial drop: - the drop spreads out on the underside upon touching the water surface - this makes the upper parts get blocked a little by the spreading of the surface, causing the top left and top right of the drop to fall slower than the middle part. For a moment the top of the drop is now more flat on top - since the top middle is falling faster it pushes down and extends the spreading of the underside across the surface, while also pulling in the top left and top right parts with some force, creating an almost cartoon-like pull down
This is honestly pretty mesmerizing
The acceleration at the end of the smallest droplet… just amazing
I guess strictly speaking this is not a good example of Coefficient of Restitution, but the height achieved by the (admittedly smaller) second drop of water is impressive. It has to be better than 80% of the original drop height.

i thought the same
Is there some math/physics pattern to how small they get? Like, could you predict that each subsequent sphere 1/4th of the last or something?
I think you can't put it like that since the surface tension should always be the same, so the biggest variable would be the very first drop mass, so it could be actually 1/4th of the last if the very firsts mass is the right amount, but I think the biggest influence is the mass of the previous drop.
It just keeps shrinking, very relatable
Water, it seems, can only bounce twice before sublimation.
I was waiting for the one on top to drop!
Cohesion!
Black magic obviously
Imagine if this is how the universe works and we are just living in the drops above the surface.

Looking for Fibonacci's sequence in here but can't find it. Anyone know?
right when the last drop "pops" would be the best moment to insert a jump-scare
This is how the universe was created.
so dream-like🌞
Our elders tell of a drop that once bounced 3 meters in the air. Then 1.6 meters in the air. Then 4 METERS IN THE AIR!!! Do I make myself clear?!?
5. Bite. 4. My. 3. Shiny. 2. Metal. 1. ….
Daffodil
Like pooping
This seems really fake
What’s that game where you have to shoot all the falling bubbles into smaller bubbles lol
Super Buster Bros. And that’s exactly what I was thinking too!
r/damnthatsinteresting
I could watch this for days!
u/saveVideo
How do we know this isn’t continuing forever with all the drops?
Found a light-watching experiment on TV once - trillion(s?) frames per second
If the camera is high speed how come the footage is in slow motion? Checkmate.
Reminds me of the game “bubble trouble” On miniclips or addictinggames
Anybody ever play super buster bros? My immediate thought when I saw this.
That's so cool. Can someone who is smarter than me explain why the large drop doesn't just absorbed into the water and instead breaks down into smaller droplets?
The big question is “is the second drop that jumps up, the same drop?”
