Strange water phenomenon - Smarter Every Day

[knifemakejake]

perhaps the moss effects the PH of the water slightly, and the resulting difference is enough change surface tensions? I see the same thing when I'm washing my car

[MegaHammer12345]

ice sicles yayyyy

[XepptizZ]

There was a time warp episode about this, it actually always happens when raining, just faster. I'd reckon that the increased density simply enforced the effect.

[JDMachinima]

I think it has something to do with the density of water that is in a frozen state. Those water droplets that rest atop the others are in a pseudofrozen state, due to their contact with cold air, and wind from there fall. Therefore they act almost like solid water. Solid water is less dense than liquid water (the reason ice cubes float in a drink), therefore the droplets act as tiny ice cubes that float upon the denser surface. Im just a physics student, but thats the most logical answer.

[persiansthebest]

@destinws2 well i saw the same thing at the science centre in canada. It was an experiment were we used our hands and made vibrations on a bole, then little bubbles started to pop out. It was really cool

[Just1Spark]

Sorry, heres the correct part. watch?v=BTGxrLqCOCo

[Just1Spark]

Here is the answer. watch?v=ubka5f1vUC8 Stan Dayo This guy duplicates this effect with Coka Cola. 

[RawKinRobby]

Look in to Victor Shauberger's work. Water becomes extra dense at 39 deg. and has some amazing properties. It's Alive!

[sethelliotttaylor]

It may just be happening because of water being cohesive

[drdewburger]

This happens with oils too. I would go with what 4forpengs said.

[bumblescum0123456789]

I see this in the shower sometimes

[CYNiCAL2009]

Apparently there is two types of water which look completely identical but they are both phobic of the other type. Not sure if this is the case here but you know..

[kasroa]

I get the same effect when I drag my Styrofoam cup full of tea across the table in work. The vibrations cause the surface of the tea to vibrate in many bizarre patterns. At a certain volume the vibrations cause small droplets to appear and glide across the surface in exactly the same way as in this video.

[destinws2]

@kasroa

Ooo... cool!

[superbranster]

I think it is just simply air getting trapped between the drop of water and puddle

[teccdeccdude231]

This video made me have to go pee.

[ethanL337]

I haven't read every comment so I do apologize if this was suggested. You say the current temp is almost freezing. Couldn't the water droplets be freezing a little bit when they fall? When the droplet is falling could there be just enough wind to cool the air around the droplet, making the surface freeze a tiny bit?

[burnEXcess]

watch?v=JjLtt2IcNGg

look similar to this

I have never seen something similar in nature till now :)

[weldrocks]

This interested me as well It seems to be Antibubbles

[gravelstone8]

The nearby rock can be giving off a surfactant. A surfactant is a soap like substance that can bind to polar molecules and nonpolar ones as well. The hydrophilic end of the surfactant attaches to the water and the hydrophobic end allows it to "float" or "skate" on top of the water (since the hydrophobic end will repel the water below it). We can see that the rock is porous because there is moss growing from it. Also, in the video we see the water droplets are dripping from the nearby rock face.

[gravelstone8]

@gravelstone8 And if the rock isn't giving off the surfactant maybe the moss is...

[destinws2]

@gravelstone8

What exactly is a surfactant?

[jmd448]

could this be sort of like the behavior you see in semi solids when subjected to vibrations, look up cymatics, its what that reminds me of.

[brianferry123]

No I was just making the association

[PRINCECOUNTYBEATS]

water can evaporate in the cold, it doesnt need to boil. its because of the difference in partial pressure of water in the atmosphere verses the water. maybe since the water crystallized it no longer exerts a partial pressure like liquid water. and theres as much a pressure pulling it on the ice as there is pulling it in the atmosphere

[brianferry123]

Hey I had to come back would this be the Leidenfrost effect

[destinws2]

@brianferry123

No, that has to do with a layer of steam keeping a bead of water skirting around on a cushion of air. This is more likely "antibubbles"

[brianferry123]

This has to be one of the cool vids ever

[KYkMan]

Water coming from the waterfall is colder and therefore more dense than the water it's falling into? Because the temperature difference is so slight, the surface of the water can only hold tiny droplets, before the temperature equalizes.

I don't know...

[0nurato]

i think it happens because the temperature differences 

[TTThienTN]

@0nurato I think the same too. I had a hot pan and i added a little bit of cold water and like a billion little water marbles were bouncing around like crazy.

[CirrowProductions]

The water could be originating from a natural spring, so there's geothermic pressure pushes it out and it's naturally warmer because it's heated?

[thephantompoet]

I would add that the effect seems to be possible because the surface is vibrating so much from dripping water. The same thing happens any time a drop enters a pool, only for a fraction of a second.

[holyguy95]

Happens in the shower

[Supermassively]

An icicle has snapped off his roof and impaled his brain. He has this terrible habit of standing directly underneath them and staring up at them. And I always say, "Destin, take two steps back and stare at the icicle from the side." And he's like, "no, I like the way they look from standing directly underneath them." It was only a matter of time.

[searedice]

This always happens in my coffee, of all places :P

[snowhare]

@10mintwo: Yes. They are antibubbles. They don't have to be fully submerged.

"Antibubbles are globules of liquid that are surrounded by a thin film of gas. They are a common occurrence, but you may not have noticed them. Antibubbles can either skitter across the surface of a liquid or they can be submerged under liquid. Antibubbles appear bright because they refract light back toward its source, similar to how water droplets in a rainbow refract light" (about.com)

[ClickTop]

It's surface tension. Search for "time warp water droplet" and check out the Discovery page on it.

[MrJohn1966elliott]

Yeah, I see ball of water float on the water river. I don't know, It is strange things. Maybe it is new.

[iGOOGLEDit]

it sounds like slime hitting the ground.

[GlenStorageCenter]

but your still a village idoit nomather how look at it

[GlenStorageCenter]

thermal energy conductivity for various types of unfrozen ground whick vent out

into a spider like gride which release energy into the top lawers of the ground makeing heat or low conductivity in other word steam moron !

there also can be high monaro deposits or national gas or under ground springs and geysers this is not my field

[GlenStorageCenter]

oh man, this is what happends when you give the villege idiot a camera,

the post there video on youtube,

there should be a law agented give villege idiots camera !

[destinws2]

@GlenStorageCenter

First time I've been called the "villege idiot". I will consider this a demotion from my current position of village idiot.

[TheDonkyPuncher]

@destinws2 for some reason I laughed my ass off at that reply.

[Supermassively]

@GlenStorageCenter The above comment is what "happends" when you give the "villege" idiot a YouTube account. There should be a law "agented" giving internet access to people with fewer than five working neurons.

[GlenStorageCenter]

@Supermassively ROFL !

HA HA HA HA THANK YOU !

[matthewraser]

@GlenStorageCenter Its funny because you call him an idiot, yet fail to answer the question, misspell "their" and "they" in the process with spell check.

[chriswilson312]

I LOVE how you call him a "village idiot" when you don't know the difference between the words they're, their, and there. That's funny.

[adder80]

@GlenStorageCenter

Just wondering if, after 5 months, you have taken steps to become less unintelligent?

[sectrew]

@GlenStorageCenter What is "agented"?

[Herestodinner]

@GlenStorageCenter Could you just, maybe, delete your channel? Thanks.

[asboxerb]

Time Warp also did a video where they constantly agitated the water in the bucket. This motion always kept enough air under the bubble for it to attach and become absorbed. I can't find a video of it on line, though.

[seebrandt87]

can get the same effect if you vibrate a bottle or glass with water.

[phlphoffman]

I want to kill icicles

[destinws2]

@phlphoffman

They want to kill us too

[horstVanB]

Thanks for the excellent video question. I have often seen the same (I think) phenomenon in the ocean when I am surfing. After a breaking wave has passed, there will be many of these "water spheres" or "anti bubbles" on the surface of the ocean. Now I know why.

[eaglekepr]

Temperature probably doesn't affect the forming of the droplet either. I see this sort of effect often in my drip coffee pot ;) Although the drops don't last more than half a second where yours seem to zip around for a bit.

[Spaeckli]

it's proof that this happens discovery channels time warp made a little video about it.

you can really see how it comes to this phenomen and i think it looks just awesome!

/watch?v=4LJxwOs2yAQ

[samarasinghenalin]

@Spaeckli Thats really interesting. So this phenomena occurs because of the surface tension and because of the fact that there is a thin layer of air between two surfaces. Also the fact that the surface tension of water increases with the decrease of temperature may help.

[Norfeldt]

Love it. Observe nature and ask questions. You are great

[snowhare]

Christ in a bucket people. I answer the man's question with the *correct* name of the effect (antibubbles) and it gets flagged as spam? If you don't understand something that doesn't make it spam.

[destinws2]

@snowhare

Thanks for the gouge.  Yeah, I'm having a hard time with closed minded trolls lately. Most of my posts are deleted by moderators on the alien site I frequent.

[Hakaanu]

@destinws2

Dude, I heard that site will give your computer viruses and the FBI will want to question you about an ursine pedophile....

[10mintwo]

These are most definitely not antibubbles. Antibubbles are a very specific phenomenon whereby a very thin layer of air encloses a droplet of water whilst fully submerged underwater. These are just water droplets skittering on the surface due to surface tension as "kowality" correctly notes below. Search for "antibubbles" on YT to see the difference.

I enjoy your channel very much and think you're quite bright. Intelligent enough even, to begin seriously questioning your own beliefs.....

[10mintwo]

Incidentally, if one wishes to investigate this phenomenon of surface droplet skittering further, the relevant term used in the literature is water coalescence; and it has been found recently that it proceeds in a self-similar finite cascade of ever smaller mergings called a coalescence cascade. The seminal AIP physics of fluids paper being "The coalescence cascade of a drop" by Thoroddsen and Takehara from 2000.

[snowhare]

The name you are looking for is 'antibubbles'.

[mrjimmyos]

Magic!

[kowalityjesus]

I believe that this is an effect of surface tension, the same thing that allows water striders to move across the surface. I assume that when the water hits the ground and bounces up in drops, some of the drops form stable spheres, whose surface tension temporarily opposes that of the water on the ground. The bond is not covalent, but related to polarity, a 'hydrogen bond' where the unique shape of water molecule causes a self-affinity at the surface.

Beautiful footage, inquisitive mind :-)

[destinws2]

@kowalityjesus

Hmm. Thanks. Does this effect have a name? Is this information scholarly or a guess? The stable spheres you mention would be created by a "worthington jet" I believe.

[mytubechannell]

@kowalityjesus Water is most dense at 4°C. When the droplets fall off the icicle and hit the water of similar temperature and density, this creates a disturbance in the surface of the pool. The droplets which break off are very dense and cool this I think extends the period of time before they break surface tension. Surface tension temperature and density are crucial here. See Pollack and Schauberger.

[kowalityjesus]

@mytubechannell It is quite rare that I have a Youtube comment not only agreed upon but elaborated upon. Thank you, sir.
