Yes, I think that was in my shooting mercury bullets video. I always assumed it was because my mercury was dirty, I never thought it could be due to electric charges!
But Cody, where would the lipids be coming from? is there soap in your mercury? something has to make the barrier layer to stabilize the droplet. I think this needs a video on your channel!
I had never seen the submerged "anti-bubble" before, but I have studied the surface phenomenon that was initially shown with the milk. Back in '79 I won the Houston Science Fair Physics division (and most original exhibit) with my "Interstice formation in liquids" project, but I had never heard of "anti-bubbles." The surface phenomenon, which involves droplets floating above the surface, happens in every polar (meaning the molecules are inherently bi-polar charged due to covalent bonding) liquid. This happens in the sink, on the hood of a car, and I've even noticed it in urinals, as well as molten solder (tin and lead). The Hydrogen atoms in water are bonded at a 107 degree angle with a covalent bond to the Oxygen, so even plain water will do this. I was able to set up an apparatus with nearly 100% floater generation, and also used dye to study the droplets. Interestingly, the addition of soap (or any surfactant) simply causes the floating droplets to flatten out, and they will often merge creating "drops" nearly 2cm in diameter. I also played around with pH, but that had no effect on the phenomenon. If I remember right, the air gap is just a few hundred Angstrom, close to the wavelength of yellow light - one experimenter used diffraction rings from a sodium lamp to measure the distance. Any dust or particulate on the surface of the liquid tends to pop the bubbles so that they either don't form, or are extremely short lived. One of the coolest things about this is that if you introduce a static electric field, the phenomenon disappears! Apparently this alters the surface polarity enough to prevent the electric charge drop levitation. Run a comb through your hair and bring it near the liquid to watch this, or just stand on a bathroom mat that makes static when you rub your socks on it: when you bend over to get a close look at the drops, they all disappear! The only research I was ever able to find on this came from two Scientific American articles in the old "Amateur Scientist" column (I would not be the person I am without reading that during my childhood). I was able to disprove most of the theories in those articles, but never came up with a full theory that explained all the behavior I observed.
I don't think there's a way to do that since bubbles and antibubbles happen in different places? one in air and one in water. question mark because who knows, there might be a way. lol
People should not play god! If the bubble and anti-bubble came together, who knows what would happen. A hole in space time? Micro black holes? A doge that did not speak in doge speak? Don't talk crazy about such things ;)
I was wondering when she was going to get to that and she never did. I was going to suggest that the soap or food coloring was increasing the surface tension of the milk enough that the droplets were able to rest on the surface. After seeing the rest of the video I think that it could possible be just like the way she explained how the antibubbles form under the liquid, except they form on the top of the liquid instead. The only area where the gas film exists is between the surface of the sphere and the milk it is sitting on. The film of air is strong enough that it allows the sphere to float on top of the milk like it was in a small boat made of air.
I think the keyword is coalescence of droplets at the interface. Such as this post at physics stackexchange h ttp://physics.stackexchange.com/questions/163013/how-can-a-droplet-of-liquid-float-on-the-surface-of-the-same-liquid
You can have bubbles or anti-bubbles that are either stuck to the surface or not stuck to the surface. Only the free-flying bubbles and the fully submerged anti-bubbles are spherical and have a double-layer going all around. The varieties that are stuck to the surface are basically incomplete, on one side they have no double-layer.
From the definition, it should be. The milk bubbles are a film of gas (air) surrounding a sphere of liquid. The definition also included "typically submerged in a liquid", but regular bubbles were also said to be "typically surrounded by gas", which we know isn't always true. In short, yeah, I think so. (And I know I messed up the quotes, I'm not gonna go get the exact ones)
I lol'd when you went "Whhyyyyy!" always wondered how bubbles work. I've seen those antibubbles before but never thought about them enough. now i know! thanks
Omg I've needed an explanation of the water-beads-on-water thing for literally forever; and the best I've ever been able to come up with is "something something surface tension something." This is much better; thanks so much! 😀👍
Regarding milk at the beginning - couldn't that just a regular example of surface tension? Pretty much same thing as water droplet on a lotus leaf. Milk is an emulsion and dish soap acts as a surfactant (deceases surface tension), which allows for unstable droplets of mainly oil in the outer layer to form. Quite easy to test as well by repeating the experiment with both skim milk and whole milk. It should be much harder to produce the droplets with skim milk If my theory is correct.
Those are not anti-bubbles, just when the surface tension of a droplet and the milk surface prevents the two mixing. All it takes is a small bit of impurity to break the surface tension of the droplet and it breaks open and mixes with the rest of the milk. Also happens with very clean rainwater on a puddle
Tony P If the bubble isn't in the liquid but instead is skimming along the top, what is stopping the droplet from just falling back into the milk? What binds the air in a sphere?
Physics Girl, do you have any idea how much this video demonstrates how biologists hypothesize the first primitive cells came about on early Earth!!!!???? OMG! :o
The soap molecules behave very similarly to the phospholipid molecules that make up cell membranes, except that they've been shown to form their "bubbles" spontaneously under the right conditions. These naturally-occurring "bubbles" of lipids could have served as a prototype that eventually developed into something we would recognize an primitive, but living, cell. They're pretty jargon-heavy, but here's a couple wiki pages with more info: en.wikipedia.org/wiki/Lipid_bilayer en.wikipedia.org/wiki/History_of_cell_membrane_theory
yea, I couldn't help but notice how similar the antibubble are to phospholipids, the stuff that makes up most of the cell membrane. they both have a hydrophilic head and long hydrophobic tails. and they are both have bi-layer, with the hydrophobic tails sticking in and the hydrophobic heads sticking out. biology girl? xd
Absolutely this could help understand what forces made the early cell membranes possible. But i think early cell membranes could have been bubbles (lipid film in water or organic solution as a medium) instead of anti bubbles.
Physics Girl is incredible I pressed like before the video started as her bubbly personality & enthusiasm for science really shines though... sorry if I milked it a bit 🤔
This is dope, a bunch of enthusiastic popular science UA-camrs linking to each others videos. Makes me feel good about UA-cam, getting kids into these science journeys.
I made some of those weird bubbles from the beginning by accident recently. I work in a very dirty job making the pvc resin (a powder) that gets melted to make plastic. I accidentally spilled some coke on my desk and I decided to try to absorb it by putting some of the powder on it. It ended up creating these small beads of powder and liquid that rolled around on the surface. They were actually very resilient and required deliberate effort to pop them. I was even able to bury them with powder and dig them back out.
Thank you! I've been wondering about these for years, after I noticed them while washing dishes: tiny beads of water rolling around the sink above the film of water. Seeing them inside the bulk liquid was quite interesting! I'll definitely have to try this.
omg i love this channel. physics with fun, thats the combination every student wants. 👍👍😍😍 it would be very nice if i could get more channels like this.
Check" smarter every day" and older videos of "Veritasium" (nowadays he's making different things) and certainly vsauce. Actually, subscribe to Vsauce ASAP
You're welcome. I wonder if you'd be interested in making a video about protein liquid-liquid phase separation. It's the new frontier in biophysics, droplets of protein separating out in water, but still staying as a solution, just an enriched one. Veritasium already made a video about alzheimer's and I think this is relevant.
That's what they call them, antibubbles! I did my physics project on antibubbles in high school, 1970....except had no name that I could find back then. I got as far as trying to photograph them with a strobe light. They can be generated without soap of course, especially when droplets strike glass, but they're much shorter lived. If they're electrically charged, you should be able to steer them with electrical polarity. This video made me think of a thousand more experiments to try. Antibubbles.....very cool, thank you kindly!
I like how multiple youtube channels actually helped in one science experiment. I almost imagine a potential future, where science and ground breaking experiments and tests no longer have to be done in labs and university's with lots of funding. But can instead be achieved from the collaboration of multiple youtube channels, and is directly funded by the community from views.
> But how antibublbes explain the balls on surface of milk? Those on the milk are called "globules." If globules submerge, they become full fledged antibubble. See amasci.com/amateur/antibub/antibub1.html, the cartoon sequence.
I saw these antibubbles when watching my mom do the dishes as a child when the clean tap water hit the soapy dish water. It always mesmerized me. I asked my mom and my dad why it happened, and neither knew.
Bubbles are as deserving of study as any other phenomena, and I for one refuse to watch your antibubble screed. Also, thanks for the beyond slow motion link.
But the milk bubbles are NOT anti-bubbles since they exist on the fluid. If you conclusion doesn't answer your intro question, you got something wrong somewhere.
Thank you for this video! I've observed the formation of these antibubbles while making coffee in my machine at home. I was always searching for what these were, but never really found an explanation, here it is!
It's a common feminist talking point that STEM is hostile towards Females. There have been concerted & oft quite costly initiatives to drive girls toward these courses of study ( with little impact, positive impact... that is ). Keep up!
That was more intelligible. Still I don't see how this video would falsify (or confirm) that. "Oh there's TWO women in a physics video so there can be no particular social challenges for women who want to get into professional physics?" - sorry, doesn't work that way.
steve1978ger You're extrapolating quite a bit there & quite obviously terminally invested in your ideology. I won't waste my time with such a disingenuous type. Why would you start trying to argue with me? If you have such an informed opinion, why would you feign ignorance to the point of not even being able to spell the word "what" correctly? ...You're welcome for the explanation troll.
WOW! This video is awesome. After 30 seconds of watching I immediately tried this experiment and I was mind blown. Your video was very educational and entertaining. Thanks!👍
Interestingly, I first noticed this phenomenon years ago but never knew how to describe it so I could find out what was going on. When I was younger I used to drink tea with milk but couldn't stand it if the tea was too hot so I used to pour a bit of milk into the tea, then stir continuously until it cooled down. While stirring, sometimes my hand would slip and the spoon would create those antibubbles skimming over the surface, but only if I'd been stirring for a while: it would never work if I'd only been stirring for a few seconds. And yes, pretty much everything physicsy that we take for granted on Earth goes topsy-turvy when you go into space. Weightlessness makes things weird, it shows us how vital gravity is to our intuitive understanding of how the world works.
5:30 - here's what I love about this channel, and about girls in science. You're not trying to be a guy, or play by male rules, or be dispassionate or clinical - you're a total girl and totally into science and it's wonderful. That transition from giddy bubbles to teary "I love science" to - WHAT ABOUT SPACE THO. I love it :)
This brings up memories of my nanny when I was four. When I would take a bath, we would play with the water until golden bubbles would appear. She called them magic bubbles
When I first moved to Montana that winter it got to about 20 below zero F, and we blew soapy bubbles outside and they freeze instantly! Then if you touch them they shatter! It's so awesome.
Probably 10 years ago now there was an article in Physics Today about how a fluid bubble can float above a fluid surface. The mechanism was drive by the bubble having a lower temperature than the water surface. The bottom of the bubble is slightly heated due to it's close proximity (but not touching) with the water surface. Heating the bottom of the bubble increases it's surface tension which pulls the bubbles surface down. The surface tension "powers" a torrid circulation pattern in the bubble. Since there's a no slip condition with the air that's in contact with the bubble, the bubble drags air underneath it. If the circulation is fast enough, it'll suspend the bubble above the warmer water surface until the temperature equalizes, killing the circulation and causing the bubble to drop down into the water surface. This is hard to explain w/o diagrams...
Small kids have been using that trick to make popsicle speed boats since the '80s in my contry. Just find a relatively quiet pool of water, break off half of a popsicle, swipe the jagged end on some detergent bar and place it on top of the water. IIRC this has something to do with surface tension and the detergent breaking that up or something.
There is a couple videos on TEDx talking about the 4th phase of water. It offers a very similar explanation for this phenomenon. More to the droplets floating on top of water. Interesting stuff.
Thank you for this explanation! I often get the little antibubbles on the surface of my coffee when I'm pouring in the milk and have been wondering what they are and how they form. Cheers!
I see thees all the time in mercury; never knew what they are called, thanks!
yeah you can see them in that video where you dropped tings into mercury at the end!
Yay ! Cody is here :D
Yes, I think that was in my shooting mercury bullets video. I always assumed it was because my mercury was dirty, I never thought it could be due to electric charges!
But Cody, where would the lipids be coming from? is there soap in your mercury? something has to make the barrier layer to stabilize the droplet. I think this needs a video on your channel!

Well its a good thing you found this video! What are the odds, also how does this only have 16 likes? More people need to see this!
I'm very disappointed that you didn't try to make a normal bubble touch a antibubble to get bubblenergy or maybe a bubblehole
That my friend, would destroy the entire earth. The Sudds clock is now at 2 seconds.
I don't think there's a way to do that since bubbles and antibubbles happen in different places? one in air and one in water. question mark because who knows, there might be a way. lol
+
Using soap to make antibubbles for energy production... that's what I call _clean_ energy.
People should not play god! If the bubble and anti-bubble came together, who knows what would happen. A hole in space time? Micro black holes? A doge that did not speak in doge speak? Don't talk crazy about such things ;)
Another interesting physics idea is nanobubbles - harder to do demos with though
Put a bubble in an antibubble
This guy gets it.
And an eletrical charge just to see what happens. Probably nothing.
The crew on the ISS love doing that kind of stuff. =)
It'll explode the universe
You become your own grandfather if that happens
What about unclebubbles?
Sounds like an excuse for the uncle to fart....
Ehh! EHHH! Lol! Unclebubbles!! (Elbow nudge) ehh!
Lol
best dad joke!
Small boobs= antibubbles
Wait, what happened to the milk bubbles, no conclusion?
good question on that
Right? She forgot what she was doing lol.

My A-level physics project in 1978 was on antibubbles.
Is it the base of qm
I'm reporting this video to UA-cam due to its hydrophobic content!
Tumblr is coming
Don't forget the antibubble propaganda.
But still it's not inappropriate content
Nice. :)
+Physics Girl Hi! ^_^
Hi, I like your enthusiasm for physics and the fact you enjoy learning new things and sharing what you learn with us all.Physics Girl you rock!
So was the milk experiment at the beginning an anti-bubble or not? I think your answer was "almost" but I'm not sure there was a follow up.
You can have bubbles or anti-bubbles that are either stuck to the surface or not stuck to the surface. Only the free-flying bubbles and the fully submerged anti-bubbles are spherical and have a double-layer going all around. The varieties that are stuck to the surface are basically incomplete, on one side they have no double-layer.

(And I know I messed up the quotes, I'm not gonna go get the exact ones)
kurtilein3 so the definition of a bubble requires this double layer? But the milk "spheres" were just caused by surface tension?
+kurtilein3 how do you know though that the milk isn't just acting hydrophobic, like Rain-X
I think, given the explanation, that those are anti-bubbles-bubbles due to the components/medium combination.
If I was publishing an encyclopedia, I would use a photo of Ashley to illustrate a “million dollar smile”. Wow! 😁 Excellent video, Dianna. 🙏❤️🌻
I guess that one would have to be verrrrrrry patient to have an anti-bubble bath.
I lol'd when you went "Whhyyyyy!"
always wondered how bubbles work. I've seen those antibubbles before but never thought about them enough. now i know! thanks
Omg I've needed an explanation of the water-beads-on-water thing for literally forever; and the best I've ever been able to come up with is "something something surface tension something."

It is, she even made a video about it

That face drop when Dan is called 'friend'. The friend zone is strong. Ouch.
Hilarious!
danuk500 ouch indeed
But you never explained why the surface soapy milk beads happen!
IKR! I've seen them on the surface of water as well. Would love to know what causes them.
Soap alters surface tension.
Those are not anti-bubbles, just when the surface tension of a droplet and the milk surface prevents the two mixing. All it takes is a small bit of impurity to break the surface tension of the droplet and it breaks open and mixes with the rest of the milk. Also happens with very clean rainwater on a puddle
Yep, those are "globules." When a "globule" is forced to entirely submerge, then it becomes an "antibubble."
What about normal air bubbles in water? Are those not "real" bubbles? Or would they be something like simple bubbles, or single-layer bubbles?
They're so cool. I always get this dorkish smirk on my face whenever I see one.
Pretty awesome... But what are the skimmers that bounce on the top??! XD
I gathered it's the same thing, you just can't see the air layer
+
+Tony P but it's in contact with air, meaning the air layer would just go away.
+Neil Gupta but the air is bound in a sphere so it's somewhat self supporting. i think this explains its short lifespan :)
Tony P If the bubble isn't in the liquid but instead is skimming along the top, what is stopping the droplet from just falling back into the milk? What binds the air in a sphere?
I love your enthusiasm for science. This is what makes great teachers, I'm sure you will help inspire many young people to become scientists.
Physics Girl, do you have any idea how much this video demonstrates how biologists hypothesize the first primitive cells came about on early Earth!!!!???? OMG! :o
I don't :(
The soap molecules behave very similarly to the phospholipid molecules that make up cell membranes, except that they've been shown to form their "bubbles" spontaneously under the right conditions. These naturally-occurring "bubbles" of lipids could have served as a prototype that eventually developed into something we would recognize an primitive, but living, cell.
They're pretty jargon-heavy, but here's a couple wiki pages with more info:
en.wikipedia.org/wiki/Lipid_bilayer
en.wikipedia.org/wiki/History_of_cell_membrane_theory
+DontStealMyFish The basis of the cell membrane is a phospholipid bilayer. It's the "hydrophilic head" and "hydrophobic tail" stuff she explained.
yea, I couldn't help but notice how similar the antibubble are to phospholipids, the stuff that makes up most of the cell membrane. they both have a hydrophilic head and long hydrophobic tails. and they are both have bi-layer, with the hydrophobic tails sticking in and the hydrophobic heads sticking out.

Certainly the word "surfactant" should have been used at least once during this.
surfactant is way too big of a work for kids these days. if you use it, you risk being accused of bullying and/or liking school.
+rillloudmother that's probably true, sadly....
Or they can google it in like 2.5secs and gain more knowledge?
It's not like 'soap molecule' isn't completely equivalent and more easy to parse.
I learned something new :")
Thank you! I've been wondering about these for years, after I noticed them while washing dishes: tiny beads of water rolling around the sink above the film of water. Seeing them inside the bulk liquid was quite interesting! I'll definitely have to try this.
Anti-bubbles are bubbles that can’t even.

hope you're joking.
Would it be wrong to say a bubble is like a magnet?
You guys are awsome keep physicsing the world needs more people like you guys
So you are a step closer to producing the antibubbles of abiogenesis...

I am a hydrosexual and I am disappointed to find out that bubbles are hydrophobic.
This was great, loved the animation, loved the slow motion, great job.
I wish my interns were that hot. But nobody else would do their job in that case.
I wish my business grows big enough to need interns
interns = poor young workers we exploit to do free labor
xygomorphic44 in exchange for experience
You are right xygomorphic44. I've been an intern too back in the day, looking back I feel they were six wasted months, good times though.
How does that matter? Interns do all the work anyway.
I know physics and chemistry but until today i wasn't aware of antibubbles and the fact that beauty and brain are miscible. Keep up the good work :)
So you guys got physical?
there seemed to be some chemistry, if you know what I mean
Nah, I don't think they mix well.
Sure, but the opposites attract ;)
+Marc Cornellà this is the best chain ever..
Marc Cornellà There are no antibubbles on physics girl, that's for sure.
Vihart= Awesome explanations for math
Physics Girl= Awesome explanations for physics/science
Ashley is really pretty
So cool! I've never noticed antibubbles before.
surface tension, not rocket science
I know. .... Can't help but shake my head in disarray.
is worse, is fluid dynamics ;)
Who said it was rocket science?

"I know. .... Can't help but shake my head in disarray."
Whoa!!! ...can you teach me how?!
I thought it was cool
Learn while playing, play while learning - cool! Keep it up!
Wow. With all the feminists going around, I thought there was no such thing as a girl in physics.
wat
It's a common feminist talking point that STEM is hostile towards Females.
There have been concerted & oft quite costly initiatives to drive girls toward these courses of study ( with little impact, positive impact... that is ).
Keep up!
That was more intelligible. Still I don't see how this video would falsify (or confirm) that. "Oh there's TWO women in a physics video so there can be no particular social challenges for women who want to get into professional physics?" - sorry, doesn't work that way.

You're extrapolating quite a bit there & quite obviously terminally invested in your ideology.
I won't waste my time with such a disingenuous type.
Why would you start trying to argue with me?
If you have such an informed opinion, why would you feign ignorance to the point of not even being able to spell the word "what" correctly?
...You're welcome for the explanation troll.
+Caalamus You must be new to internet if you take "wat" as a spelling mistake.
I Love your way of talking about science :)
great work Dianna!
You are the whitest white girl I've ever seen. And I'm old and white.
never would have guessed you're some old white dude from this comment...
WOW! This video is awesome. After 30 seconds of watching I immediately tried this experiment and I was mind blown. Your video was very educational and entertaining. Thanks!👍
Ashley is hot AF
Interestingly, I first noticed this phenomenon years ago but never knew how to describe it so I could find out what was going on. When I was younger I used to drink tea with milk but couldn't stand it if the tea was too hot so I used to pour a bit of milk into the tea, then stir continuously until it cooled down. While stirring, sometimes my hand would slip and the spoon would create those antibubbles skimming over the surface, but only if I'd been stirring for a while: it would never work if I'd only been stirring for a few seconds.
And yes, pretty much everything physicsy that we take for granted on Earth goes topsy-turvy when you go into space. Weightlessness makes things weird, it shows us how vital gravity is to our intuitive understanding of how the world works.
I have also noticed this when just pouring normal milk into a glass.
I love tea, too.
Trying to be funny, you only sound awkward.
That's mean.
I think she's perfect the way she is - very "bubbly". :)
I love her videos - continues to feed my curiosity for the world. :)
He's anti-bubbly is all :P
I'm not being mean ( or jealous, +Harry PAnnU ! ).
I'm just giving you an honest feedback as a viewer.
No! Don't listen to him!
You sound adorable when you try to be funny. It's the cutest thing ever.
keep doing it.
5:30 - here's what I love about this channel, and about girls in science. You're not trying to be a guy, or play by male rules, or be dispassionate or clinical - you're a total girl and totally into science and it's wonderful. That transition from giddy bubbles to teary "I love science" to - WHAT ABOUT SPACE THO. I love it :)
very hooked nose
This brings up memories of my nanny when I was four. When I would take a bath, we would play with the water until golden bubbles would appear. She called them magic bubbles
That eye movement @2:16 is something else
Awesome phenomenon and awesome video!
When I first moved to Montana that winter it got to about 20 below zero F, and we blew soapy bubbles outside and they freeze instantly! Then if you touch them they shatter! It's so awesome.
I have been searching for the name of these things for years, I make them in coffee all of the time. Thanks!
Back when I was a dish washer I would look for these every night
Probably 10 years ago now there was an article in Physics Today about how a fluid bubble can float above a fluid surface. The mechanism was drive by the bubble having a lower temperature than the water surface. The bottom of the bubble is slightly heated due to it's close proximity (but not touching) with the water surface. Heating the bottom of the bubble increases it's surface tension which pulls the bubbles surface down. The surface tension "powers" a torrid circulation pattern in the bubble. Since there's a no slip condition with the air that's in contact with the bubble, the bubble drags air underneath it. If the circulation is fast enough, it'll suspend the bubble above the warmer water surface until the temperature equalizes, killing the circulation and causing the bubble to drop down into the water surface. This is hard to explain w/o diagrams...
Awesome footage and yay for accent nail!
Small kids have been using that trick to make popsicle speed boats since the '80s in my contry.
Just find a relatively quiet pool of water, break off half of a popsicle, swipe the jagged end on some detergent bar and place it on top of the water.
IIRC this has something to do with surface tension and the detergent breaking that up or something.
There is a couple videos on TEDx talking about the 4th phase of water. It offers a very similar explanation for this phenomenon. More to the droplets floating on top of water. Interesting stuff.
Thank you for this explanation! I often get the little antibubbles on the surface of my coffee when I'm pouring in the milk and have been wondering what they are and how they form. Cheers!
I miss this old format. It was so much more fun and there were more videos. Feel free to switch back, any time. X.
Could watch you all day... Lol. Great videos!
Mind=blown. This is a great channel. Really.
Okay. Just before I even watch this video: The word "Antibubble" makes me chuckle lol
