What are antibubbles? 

I see thees all the time in mercury; never knew what they are called, thanks!

I'm very disappointed that you didn't try to make a normal bubble touch a antibubble to get bubblenergy or maybe a bubblehole

Another interesting physics idea is nanobubbles - harder to do demos with though

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.

Put a bubble in an antibubble

Wait, what happened to the milk bubbles, no conclusion?

What about unclebubbles?

My A-level physics project in 1978 was on antibubbles.

I'm reporting this video to RU-vid due to its hydrophobic content!

I guess that one would have to be verrrrrrry patient to have an anti-bubble bath.

But you never explained why the surface soapy milk beads happen!

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

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.

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!

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! 😀👍

I love how Dianna's so enthusiastic about antibubbles

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.

Anti-bubbles are bubbles that can’t even.

If I was publishing an encyclopedia, I would use a photo of Ashley to illustrate a “million dollar smile”. Wow! 😁 Excellent video, Dianna. 🙏❤️🌻

"this is my friend, Dan." *Dan looks so sad*

1:37 That face drop when Dan is called 'friend'. The friend zone is strong. Ouch.

Certainly the word "surfactant" should have been used at least once during this.

i've been exposed to audible sponsored videos for maybe 2 years now, and i go and get myself a kindle. reading>listening

This is dope, a bunch of enthusiastic popular science RU-vidrs linking to each others videos. Makes me feel good about RU-vid, getting kids into these science journeys.

Physics Girl is very bubbly (or antibubbly). :)

Pretty awesome... But what are the skimmers that bounce on the top??! XD

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.

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.

You should have Dan on more. I like that guy.

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.

They're so cool. I always get this dorkish smirk on my face whenever I see one.

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!

But how antibublbes explain the balls on surface of milk?

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

One of the best science channels on YT. Love it. Keep it up.

Awesome! Best anti-bubble tutorial ever. I've tried a few times before and never had any luck.

Don't forget to suds-scribe

You have an intern?

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.

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.

3:53 Hydrophobic ends in contact with water? Correct it with an annotation.

So you are a step closer to producing the antibubbles of abiogenesis...

just found this channel, im really liking it, it could get kids/teenagers excited about science for sure!

I was running my CNC mill and noticed this with the flood coolant, cool to have an explanation!

Would it be wrong to say a bubble is like a magnet?

so what was the first type of bubble?

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.

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.

Has anybody ever noticed how this happens in urinals (sorry ladies)? I have wanted to make a video on this same thing for a while now!

What about in space????

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!

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

your intern is a solid 10/10 holy hell

can anyone make an HD wallpaper with the images at 0:53 and 0:56?

I have searched so long for this. Every time I aggressively blow on my mug full of tea, to cool it down, antibubbles float across the surface to the back of the mug. I suppose that tea (milk, no sugar) may be an easier method of creating them, though they are shorter lived. Thanks Physics girl.

Learn while playing, play while learning - cool! Keep it up!

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.

Surprised that there have been no comments about the fact that Ashley is an absolute fox.

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!👍

I Love your way of talking about science :) great work Dianna!

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.

Smart girls are definitely more attractive. Anti-bubbles have blown my mind. That is awesome!

This was great, loved the animation, loved the slow motion, great job.

I really like how enthusiastic she is. A good role model for how everybody should feel about their jobs/hobbies!

I would love to smoke a joint with her.

I am a hydrosexual and I am disappointed to find out that bubbles are hydrophobic.

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 :)

Most fascinating thing ive seen in a while..Awesome!

I wish my interns were that hot. But nobody else would do their job in that case.

So you guys got physical?

i swear that this channel should have way more subscribers

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!

surface tension, not rocket science

Ashley is really pretty

Okay. Just before I even watch this video: The word "Antibubble" makes me chuckle lol

I have been searching for the name of these things for years, I make them in coffee all of the time. Thanks!

You are the whitest white girl I've ever seen. And I'm old and white.

Ashley is hot AF

You guys are awsome keep physicsing the world needs more people like you guys

wow so nice you found the fun and enthusiasm and convey it contagiously

Wow. With all the feminists going around, I thought there was no such thing as a girl in physics.

Trying to be funny, you only sound awkward.

You explain it best and therefore deserve a higher acalade than the others

Could watch you all day... Lol. Great videos!

very hooked nose

Vihart= Awesome explanations for math Physics Girl= Awesome explanations for physics/science

Awesome footage and yay for accent nail!

I have frequently seen natural antibubbles during rain storms as rain drops fall into puddles of water

I miss this old format. It was so much more fun and there were more videos. Feel free to switch back, any time. X.

Back when I was a dish washer I would look for these every night

Wow, so cool! I'm glad youtube recommended this video... I subscribed!

she is so much more interesting then my physics teacher

So cool! I've never noticed antibubbles before.

Anti-bubbles, a sure sign that a toddler with a bubble wand divided by zero on accident

I saw one of your videos at school and decided to check out your channel on my own time(I know, lame, right?). Your videos turned out to be really informative and interesting at the same time. Thank you!

Aren't we all just beads of milk floating across the paint until we all get reabsorbed

Mind=blown. This is a great channel. Really.

My mind has just been blown into a bajillion antibubbles

wow...that was so imfomative... i never knew anything like antibubbles existed! good job!

I'm drunk, makes me notice the pbs into sound hits my serotonin (I think that's the one). I love pbs spacetime and really coming to love this channel as well
