Your ability to find the most mind blowing things in the most mundane things in life is amazing.
Thats the best part of this channel
You do know all of this science is found in books and science papers. He doesn't "INVENT". If you go looking for answers to everything you will find a lot more questions
Maybe it's more accurate to say that nothing is truly mundane?
He likely got the idea from Posy's video on this called "Hot Water Colors"
Thanks. Now my friends think I'm weird. "Why do you keep staring at your hot chocolate? "
Lmao 😂
I tried explaining it to my parents, they just called my therapist…
Don't worry, they already do.
It's ok! When they say something you just have to... blow up a balloon and rub it on your head and then walk towards their mug. Totally normal XD
@@user-bt2lx4gy7h How did you know?
that's pretty cool, I cant believe i never noticed that before!
@TheBackdoorScientist I think we need a new Safety Third guest!
Hello there, mate
it's the backdoor scientist !
Honestly, I'm not surprised that you and we never noticed. I could be misunderstanding what he is saying, but it seems that we need to look at it with that lighting angle, which is almost impossible for most people, because that lighting and position is not useful.
Jesus loves you ❤️Please turn to him and repent and receive Salvation before it's too late. The end times written about in the Bible are already happening in the world. Jesus is the son of God and he died for our sins on the cross and God raised him from the dead on the third day. Jesus is waiting for you with open arms but time is running out. Please repent and turn to him before it is too late. Accept Jesus into your heart and invite him to be Lord and saviour of your life and confess and believe that Jesus is Lord, that he died for your sins on the cross and that God raised him from the dead. Confess that you are a sinner in need of God's Grace and ask God to forgive you for all your sins through Jesus.
Time is running out.
Looks like this is a great idea for the slow mo guys to film
omg omg omg YES, this comment needs to be highlighted and shared to Slow Mo guys!
I would watch that.
Slow mo cosmic rays are pretty fast mo. Upper limit is 1000 ft per frame at 1,000,000 fps.
well I think you'd be capturing the propagation of the lines more than the cosmic ray@@DrDeuteron
@@zachhoy if the lines are from cosmic rays, they propagating that fast.
It’s nice when people present things as “first described”, “first explained”, etc instead of first discovered for things like this.
I agree, also I highly suspect that boats were used long before western history gives credit for. To a lesser extent I expect the same with hot air balloons.
“Described” suggests the conscious putting down on paper or clay tablet, so is closely tied to the recording of history. It’s rather like the Schrödinger’s Cat dilemma. Before being described the event is in a meta-state of being known/unknown. But we may later discover someone who looked at the cat earlier and noted down it’s state of health.
I'm always impressed by how novel your videos are
Exactly
Every time I see one of his thumbnails I'm like "oh I know about cloud chambers. Eh, might as well click anyway in case there's good footage". And then it turns out to be far more interesting and not at all what I expected. I really should have learned by now
I've been watching for years thinking "Any day now this guy's going to run out of weird shit to show." nope, it just increases. I am happy to have found this channel. He's so odd but so cool at the same time.
Yeah a lot of them seem like dumb experiments at first glance but sometimes find some unknown phenomena
Love how he's just calmly speaking while his geiger counter is losing it
Edit: God yall have no sense of humour
You probably mean giggidy counter
lmao @@pykapuka
As a German I can tell, calling him "Giger" is really funny
Why would he talk differently?
ameriseeium
THIS is the content I love from you. Seriously please do more of this. You're taking something that is genuinely interesting and doing some actual science to figure out what the heck is going on. One of your best videos to date.
yeah exactly!
Your curiosity is infectious and your ability to relate complex scientific ideas to everyday life is unique.
This is just a guess , but may be the reason water droplet form on top and just doesn't mix with rest because , water droplet are pure water while rest is mixture (tea or cocoa). Which result in difference in composition, thus slower rate of diffusion.
Interesting guess but the droplets are fully levitating, they don't make contact with the water at all until a micro-ripple bumps into them and then they're instantly consumed.
This effect works with just water
Surface tension
@@DrDeuteronthat's what I was thinking. But surely they must've disproved that somehow if it wasn't mentioned as a theory.
Very cool experiment! I also suspected that the levitation is caused by a tiny electric charge :)
Hello checkmark person!
Nah I'm kidding it's cool to randomly see you Posy, love your videos :)
@@First_Grafter less random in this case because he also made a video about this phenomenon
@@sopphi OMG I totally hadn't seen that before, makes a lot more sence then.
Hi Posy. 🥴
Love you man
Hope to see your new music on Spotify soon
I went through this exact thought process when observing this very effect on the surface of my morning coffee. Ended up concluding that the convection processes would dominate any movement compared to the relatively weak effects of any possible cosmic rays.
I'd love to see you repeat this experiment with an alpha and beta ray source to be sure though!
It would be neat to try this in a really shallow container. That should suppress convection and you could see if crack patterns still formed.
1:05 Well the droplets are incredibly light, light enough to float around in wind. And the droplets have to touch the bulk liquid, but air is in the way. Regular water will also float around on regular water in some conditions
"These are blocked by the platsic...."
The Geiger counter starts screaming. XD
He means the alpha particles from the primary decay are blocked, but was surprised that some gamma radiation was being produced as well (which isn't blocked by plastic).
@@ferrumignisYeah, explained well what he meant, it still was funny. Also, efficiency of detection of gamma is not the same for all Geiger counters, there could be more. I did not realize that there was so much secondary gamma produced.
@@ferrumignisplatsic*
Get out your Radiacode, and find that the smoke alarm is spewing x-rays. "Gamma rays," but they're around 30KeV, less photon energy than dental x-ray tubes.
You have one of the best science channels. Always coming up with original and random topics that are both fascinating and educational. Keep up the great work!
This makes me want to watch Posy's video on this effect. He does a great job capturing the droplets with a macro lens. It'd be cool to see y'all do a collab on something.
Highly recommend youtuber Posy who did a video on this called 'Hot water colors'!
The power of observation
Observation really is all we have if you think about it...
I've been wondering about this for some time now. Thank you for covering it!
You always came with a unique idea. Thanks for teaching us. ❤

bzzzzz@@Cannotoad1201
Suddenly a magical world appears!
Tritium illumination sights also emit secondary gamma. It’s not much, but it’s detectable. I wouldn’t worry about Tritium illuminated watches, Gun sights, and keychains.
Posy has a fantastic video on this if you want to see good close-up footage of the levitating dots.
The drops are where the water is vaporizing and condensing pretty much instantaneously. Water heats up, vaporizes, then loses heat to either air particles or other vapor particles even, but it causes condensation under the wall of steam (count the steam as a ceiling and the air gap beneath as a cooler system). The faster particles brush by and slow their momentum enough that they lose thermal energy and cool down just below the temperature, but, they cool so close to the surface temperature that the heat difference is extremely small, so heat transfers slower. This keeps it as approximate condensing temperature, but bouncing just above and below this temperature for a time. But, once the convection currents reach a cooler state, more particles can fit into that cooled state, absorb heat and fluctuate also.
I suspect it is the heat that gets trapped in that space (the difference between the lower interaction and the upper interaction being minimal), so that, when enough particles get there, their activity becomes excited, pushing more vapor around and allowing for cooler air to be exposed, which allows more water to evaporate. The electric charge accelerates the water molecules as a diamagnetic substance and the added motion equals added heat (so more steam, as it takes longer to fill the "heat vacuum" left behind so more particles can evaporate due to the added energy to the system).
But that's just how I see it.
7 minutes in and I realise I'm not watching a short.
This is so well done!, Thanks for the quality production! it feels in another level
I feel the convection draws air down at certain points which the drag on the water particles overcomes their electrostatic repulsion to the point where they collapse in on each other like an electrostatic lightning bolt.
someone else said its probably micro-ripples in the fluid that are bumping into the bubbles and consuming them, it makes sense that those convection currents could be causing tiny tiny waves on the surface
@@SpydersByte also possible that at the convection lines, the temperature is different. causing different surface behaviors.
Found this a couple of years ago while looking at my tea and couldn't find anything online (was hard to search properly). So cool to see an explanation!!
Do the bubbles actually levitate, or is it just surface tension? Could it be a kind of reverse Leidenfrost effect?
It's got to be because they are charged, they space out from each other but also the main liquid. Eventually the charge leaks till they touch.
When he first mentioned about the droplets above, surface tension immediately went into my head. I wonder why he didn't mention that. He could've mentioned that it is or it is not surface tension.
I doubt it could be because they are charged. The droplets can stay away from each other because they are charged, and be pushed back into the surface because you hold a similarly charged object above them. But the water itself conducts electricity, especially when flowing like that. So the droplets should attract the opposite charge in the water, and be attracted to that.
The water would have to be charged a lot to prevent that from happening.
I would guess as well, that the droplets are floating on the water vapour coming off the surface.
It would be interesting to see how the behaviour changes when the cup is charged. Or when an oppositely charged object is held above them.
Or is there a layer of fat from the cocoa on top...
@@aalert The composition of the liquid is relevant. However, the first observation of the phenomenon as shown in the video was on tea; traditionally, the Japanese drink their tea without milk. The cocoa in the video was mixed with water, and powdered cocoa is defatted; I have seen fat globules in the British brand Cadbury's only.
So, no, in this case, the composition of the liquid appears to be irrelevant. Question is, would this phenomenon happen in pure hot water? Distilled water?
Man, you come up with the most awesome videos and examples. So often so simple, but so incredible and insightful. Thanks for so many years of intrigue!
4:23 “but these are blocked by the plastic”
Proceeds to beep crazily
In the Aussie desert, the dust bowls are, or used to be before they sealed the road HUGE. If on a dead still VERY hot summer day , back in 1958 I noticed this!
Get down really close to the dust, there is a mist of the finest dust partials over the surface, as I remember it was about a centimeter thick, thin enough to see through it but you could actually see the partials dancing in the sunlight!
The thumbnail is rather misleading, saying “cosmic rays” with no question mark. Very interesting video otherwise.
Fussing over the thumbnail? 🙄
🤓
Holy thing.. Im almost 50 and I wondered what are these lines from being child. And yes I know of bubble chamber.
This man made an entire interesting video on the steam above a cup. Give this man his award, please.
Holy moly i was just thinking about this and playing around with it yesterday while I was daydreaming around my coffee cup. Insanely convenient timing!
Hot chocolate made with water....how gross
It was the first thing I noticed… yuck!
First of all, the latin americans started to drink chocolate with this method of cacao and water.
Some powdered hot chocolates already contain powdered milk
Agree
They make it like that in the US, it's nasty
I saw this phenomenon once while enjoying some coffee and always wondered what caused it! Thanks for the awesome and informative video!
It's kinda like reading the cocoa 😂
I'm so excited to watch this. I have been wondering this very thing for a while now!
Edit: Can you please provide the citation to the researchers who thought it was cosmic rays? Also, I wouldn't expect a cloud chamber to be sensitive to gamma rays, since they have a tiny differential cross-section. Alphas would be your best bet because the energy is all deposited in a short distance; just don't drink the hot chocolate.
Lost interest at the sponsored section. Please don't promote such an extremely unethical company who have been found guilty of selling their customers' data even after saying they wouldn't do that.
But that doesn’t relate to the physics lesson
you’re currently using youtube, owned by alphabet which makes most of their money via your data. in this day and age, you have to assume everyone is selling your data, and the best you can do is keep tabs on your sensitive information. with the tools and services available online, i guarantee someone can find more info on you than you expect just by your username. data sales is pretty much low hanging fruit when it comes to unethical practices. actually, it’s more like rotting fruit on the ground at this point.
@@iamslfyou live in a society yet you partake in it, I am very clever and intelligent
Why is it unethical?
You are living in capitalism. You are going to have a hard time living ethically. What you are trying do to is just a illusion of fighting something wrong. Wanna make things right? Fight for capitalism end.
I made a reddit post in r/sciences a month ago where I asked about this phenomenon, I'm happy to see a video that goes through all the theories and questions we had on this subject. Thanks a lot !
A Youtuber called "Posy" made a beautiful video (Hot Water Colors is the title) about this. Don't think he went into the science part, but he made amazing footage with this!
Yea I would highly suggest to watch that video. It is beautiful!
@@partydogg0posy did go into the science part a little bit in his video, I think he read the same paper that describes the droplets having a charge, nad linked the paper in his description
Now i understand. Coffee + static electricity = cosmic rays need a coffee. Right
Wait... did you just create ball lightning? (A small spark/ember from a strike, floating around, but under charge and thus causing a mist "ball" around it?)
The "floating around" part is missing, here the charged ball is held on a stick. The very mysterious part about ball lightning is what is capable of floating around and maintaining large charge and how
St Elmo's fire is maybe more closely related to this. Charge on a stick, when pointy enough, does not just do things to the mist but actually ionizes air so it's shining
Interesting video, but the smoke alarm experiment isn't really enough to rule out cosmic rays. At ground level they're mostly muons, which are much more ionising than photons, and it is conceivable that they could locally disrupt the droplets in much the same way as your external electric field. Beta radiation would be a much better model. Still, a really great video on a cool topic, thanks for making it!
Wonderful explanation but please stop making hot chocolate this way 😭
❤
this is how you make hot chocolate . drinking milk when you are not baby enymore , is like suckin on mothers breast when you are grown up , grose
A whole other video would be "how to stir pure cocoa into water".

Its amazing, hes been doing it for so long and yet he always finds some new phenomenon that we can show through experimentation. And makes it fun to watch! I'm honestly in awe.
@reinux - 2024-03-23
They've gotten better as the channel got older too
@tdk99-i8n - 2024-03-23
Uniquely substantive experiments and the same low budget production for years. It's the most sustainable combo to avoid burnout and I hope he never deviates from this formula. It's actually wild to see a YouTuber today grow their viewers so much without engagement hacks and dumbing down their content
