This is one of the most beautiful pop-science videos ever created. Excellent job!
Physics girl brought me here, this is very cool experiment ❤🙏❤
This is embarrassing. In all my years of hoarding science and DIY videos, I have arrived to this lovely portrayal of physics only now when the video has 834 likes when it should already have 1M. Bravo the the team! I found this video from a reference from Physics Girl on UA-cam. I've already subscribed. Best to all! :)
Alguien viene de un poco de todo

This is so poetic, the music and everything else !
So so so beautifully made video
This is my favorite sailor moon song
Beautiful and cleanly explained as always. Great work!
Brilliant job explaining the basic concept, guys ! Keep it coming. :)
Absolutely incredible.
That is so beautiful.
Great demonstartion of surfactants.... even if no soap is used
Amazing !
Dislikes = fanbois of fluid simulations on low-performance computers that look like shit that are used in SF movies
if silicone oil experiments would be used instead, SF VFX would be fucking fire.
Cool imagery. Science is beautiful.
Cool
Are you sure this is due to the evaporation of the alcohol? I'm sure evaporation contributes to some extent to this, but I think the much more important factor here is the alcohol dissolving in the oil, which should result in the water forming droplets as well.
I really like all your videos though!
Superb
Do you play Rhythm Heaven???
un poco de todo? jaja
Why does the water float on top? I thought oil floats on top of water? Is sunflower oil very dense? Or is the drop so small it floats on top of the oil's surface tension?
That's a good question. I've noticed that small water drops added to a pot of sesame oil sink to the bottom...
It's maybe because they are using a very thin layer of oil and the water droplet only looks like its floating on top but is actually on the bottom.
why the ejected droplets seems to be smaller and slower reaching a circle limit?
The ejected droplets become smaller because their alcohol evaporates. They slow down because they're traveling further away from the center where the difference in surface tension is driving the outward flow that ejects the droplets. The droplets in the middle are bigger because most alcohol was concentrated in the middle, so the evaporation was slower there.
What oil did you use?
I am pretty sure they used the sunflower oil throughout the whole thing. 0:09
Is this an example for Reaction-Diffusion process? The patterns resembles some patterns as in Gray-Scott Model ( mrob.com/pub/comp/xmorphia/ )
No reaction going on here, so no reaction-diffusion ;)
This perfectly describes the entropy death of the universe, from the big bang till the inevitable heat death of everything.
Entropy isn't real
@@coles5451 then why are you so ugly? 😜
thats how matter in universe expending
Moar.
None of the text in this video is legible. 😑
