What do raindrops look like? Exactly how we drew them as kids, right? Wrong! Teardrop-shaped rain is physically impossible. This week I went inside a vertical wind tunnel to bring you the true shape of rain.

I've always wanted to make it rain.
Did you learn something from this video? Let me know what you thought! And also tell me how awkward I looked indoor skydiving!
you looked really awkward 10/10
Super awkward sorry man I am telling the truth
make it rain ayyyy 8)
Yes ! thank you. Keep up the good work.
Really interesting idea
Do more videos on creative topics
Scientist 1: I'm going to research the shapes of raindrops.
Scientist 2: No, you can't. We have more important things to do right now.
Scientist 1: I was going to save it for a rainy day.
*laugh tracks plays*
I did not understand the joke
Master Therion your jokes used to be funny.

Rain drop
Drop top
Tear drop shape turns into blob blob

Came to the comments to find this. Was not disappointed.
anastasia better joke than most of comedian I know in a short comment
Reminds me of my slither.io name.

You took my jooooooke~
Could you make a video about chromostereopsis? That effect where red and blue 2D images seems to be 3D
It basically works by letting each eye see only one of the 2 colored images (for example, through the red lens, you can only see the blue image), and since the we images are slightly different, they work like the eye: both eyes are in different points, so they'll see a very slightly different image of what you're looking at. The 3d glasses work by letting each eye see what it would see if the objects were in 3 dimensions. Therefore, the brain interprets the images as a 3d object.
Or orange and green
thanks,
I finally know what it's called.
we need a vid on that. Underrated comment
I think vox has a really good video you might be interested
Teacher: Draw a rain drop.
Me: Draw pancake drop*
Teacher: That’s not a rain drop!

Yes. Yes I did. But in this case it can also be a he.
Lmao!
0:40 Why is that the most PERFECT Raindrop I've ever seen in my life??
It is wrong tho
Because it wasn't. Lol
nope
Nisha Prabha did you even watch the vid smh
Vimal Singh Isn't that random?
I love this question. A raindrop shows us how beautifully and surprisingly complex the world around us really is. Our cognition runs on a low resolution filter of the world 24/7. But there is so much more complexity in every little bit of detail. So yeah for raindrops and it's okay to be smart to show us how low resolution our perception of the world really is.
I love this comment. Thanks!
"Our cognition runs on a low resolution filter of the world" - I like that. That was one of the most poetic comments I've seen on TH-cam!
Wow a poetic scientist
@@TommoCarroll Thanks for your nice comment. I honestly just wrote what I was thinking at that moment. I'm very grateful it resonates with you.
@@mysticcocoa8886 Thank you Cherry for that compliment. I wish my paper reviewers would agree with you.
This version of 'The Shape Of Water' was way more instructive.
how did you even get subs with out content!?
No doubt in that

I thought rain drops were lines...
Motion blur
I seen it on anime
I always knew they where not teardrop shaped (also i took a pic of them) but my man i think u have been playing minecraft too much
I also thought that they were lines. Like in minecraft. It kind of makes sense because then they would have the least air recistance so i still don't understand why they are vertically flat... that gives it so much air resistance that it doesn't make sense that they stay in that shape
Lol
“Blob shaped” such scientific 😛

"Such scientific"
Off topic but, am I the only one thinking how he could draw the raindrop so nicely in one stroke? 😅😅😅
Maybe not in 1 try tho
no

When does it rain money?
When there is "change" in the weather. 🤪🤪🤪

Also, nice Heisenberg reference.
You can also notice these shapes when it hails
You take so much efforts for each of these videos. I wait for them every week. You are a true creator, not just a youtuber.

I swear everything we were taught in school turns out to be wrong. What even is the point of school🤔
Sebastian Elytron, the point of school is to teach you how to figure things out and not learn by rote.
To assimilate you to the needs of Illuminati Borg Government. 😜😂
Shur'tugal Vodr haha...shhhh....don't tell them the secret, you'll blow our cover!
I don't ever remember being told that raindrops look like that. Anyways, almost all of my teachers have told me school isn't meant to teach you everything you know, it's to teach you how to learn everything you will know
@@eyekosaeder5387 OY VEY
This is now one of my favourite TH-cam sites. I'm 71 and this site makes learning fun.
I have a very distinct memory about pancake-shaped drops splitting. They weren't really raindrops: I was on Iguazú Falls on top of a waterfall, and as drops of water went down, you could see from up there how some of them, too big to remain spheres, essentially formed a ring and then multiple smaller drops, all in a split second. My mind was blown when you showed the exact same thing here (except seen from the side).
Poor elephant :(
0:37: WRONG! If i was asked to draw a raindrop i'd just make a dot because i'm lazy af, but a dot is just a microscopic blob, which means i'd be right😁
I will draw strokes, because motion blur
Nice flag! Res, zelo lepa
i’d draw a realistic one
i mean like shading
I really love the pace of this Video.
This is a very interesting video, learning about raindrops. Keep making those amazing videos!

Oh yea
Bendy hand also
thats not mickey
Jokes on you, that’s no raindrop, that is a fine tear drop my friend
Oh my god! This video really helped me a lot! I was doing a class project and we needed to know information like this, and I watched this video and it helped me a lot! Thanks so much! You deserve a sub! :D
I've done indoor skydiving. So much fun.
0:14 when she hits you with that " I'm 15"
Then what about those giant rain drops that hit like a hail of bullets made out of water?
They might be the 3-5mm droplets forming closer to the ground.
FormalThread479-Minecraft
I also expect that lateral winds can get them going faster than terminal velocity.
Anything going fast enough can sting when it its you.
Or maybe thats actually just hail.
I love the fact that this channel answers questions i never asked but i want the answer for
Really love your videos Joe there in 2021 in Australia they’ve really helped me get through our last 18weeks of constant lockdown. Thanks 👍🏻👍🏻👍🏻
I think most of us knew this already but just never thought about it seriously. There are lots of slow mo videos of rain on TV and the internet.

Indoor skydiving looks like wicked fun, you look like a massive kid in there =P
Cool stuff. I saw a slow mo video of a drop of water and the way it kind of spins around on itself is beautiful and how different temperatures at certain altitudes have rain turn into either snow or hail.
Fantastic episode! Thanks.
*CONGRATULATIONS YOU ARE SMARTER THAN BEFORE* ☺☺☺
2:25 oh my what the heck happened to his neck that's creepy XD
A few times over my ~40 years, I've experienced rain that was big. Like really big. Perhaps hail that quickly melted? Drops that bunched together? Of the few times I can recall this happening, it seemed like these big drops were spread further appart. It wasn't like a hard rain that comes in an almost wall. It's big drops, further appart. It's pretty neat really.
Back in the late 80's, in south central Kansas, I remember a TV station explaining this on the news. Since we only had four stations where we lived, and three had local news (the fourth was KPTS - 8, a PBS station) it was either KSNW -3, KAKE -10, or KWCH -12. I can't remember which one.
3:43 He should’ve let you hit that glass 😂
5:20 XD
this is why the rain is not damaging our roof.
1:18 wow, i loved the molecules of a waterdroplet holding each otehrs hands wow so cute.
Very clear and interesting explanation
Now the question is "are teardrops the same shape that we have been drawing since childhood?"
You didn't ruin my childhood since that was in the past and it can't be altered!
Thank you I really enjoy your content. You have a wonderful speaking voice.
Your channel is awesome 👌at explaining simple things
Same with the heart. It don't looks like this ❤ it looks more like a potato🥔
Channel name : "Its okay to be smart"
Me : Its fun to be smart !
That was a very very interesting video, thank you Joe and team
I just wanted to say that I love your videos, they make learning fun and exciting and also, my friend got me a Kiwi Co. Tinker Crate and it's one of the best gifts I've received. :)
*_Speak to the water spirits!_*
Hank is my fave host I say we see more of him
The only thing I see wrong with this is that the rain drop is not moving. In order for that shape of the rain drop to appear, some of the water would have to fall behind the main drop(the drop would have to be moving). In a wind tunnel the air pushes the drop at a certain speed but also at a certain height. If you speed the fan up or slow it down the drops would go higher or lower but more or less sustain the same height relative to all the other drops. If all the drops want to be at the same height then it makes sense for it to spread out into a pancake shape or stick together in a ball shape but you would not get the tear drop shape because you eliminated the factor that potentially created it: movement(or free falling at terminal velocity).
I suggest putting a high speed camera outside while it is raining to really see what they look like. Or conduct an experiment where you drop water from a high place and record it as it falls.
You make learning actually fun and I actually want to learn
I think they look like drop tops
Trunks popped?
Oh, of course
It's Okay To Be Smart what you know about that 😂😂😂😂
You're incorrect. If you told me to draw a raindrop, I'd draw a hyper-realistic, fully-rendered image of a raindrop falling through the sky.
I LOVE your channel name *its ok to be smart* dang
I came here because I wondered why water was spherical when it’s on the ground, and why it didn’t just depart into millions of molecules. Thanks for giving me the answer!
I thought rain was lines
So Lil Wayne's tattoo makes no sense.
It's like to ask someone to draw a star, they'll probably draw a pentagram but instead should draw a circle/sphere.
I loved this! thanks
So it doesnt look like 💧💧💧???
no it looks like 🍔🍔🍔
Also o, or 🥞
You sound different. Like you have new teeth.
Why would you think that the reason someone sounds different is because they got new teeth? Out of all the other, more normal reasons someone sounds different than they do normally. Like seriously man. Who goes out and spontaneously gets new teeth?
How do you get new teeth at all? Like a new FULL set of teeth any way, cause mine aren't looking to white right now. Also do the shape of the teeth make a difference to the sound of your voice?🤔🤔
Maybe he's wearing those invisible braces
he got a new neck maybe
Love when videos tell me I'm wrong when I was right.
I did ifly before when I was in Houston so much fun. But great vid
stop using imperial units. pls use the metric units
Learn to convert
eclipse no
they are a american based broadcast
their demographic are young americans
young americans are taught imperial
till that changes.. doubt they will either
they should however always include both
Yea thats exactly right. We dont really care who it may inconvenience, thats not our problem. Its a you problem.
Dont watch american made videos lmao
please make a video why our genital area is not same as the rest skin colour
Mine is...
I don't think that's normal dude
R u ok m8?
You either
1) Have a diesease or rash
or
2) You have a tan
YOU GUYS ARE MARVELOUS.
I like these water molecules skydiving and holding their hands at 2:09
They look like my tears after my dad made it in prison
Xd...
Wow all these celeb scandals. 😨😨😨
Me ok crap vid again life noggin viewers watch this instantly clicks play
Great video. This ties in very well with the folks who make spherical lead shot by dropping molten lead from a tower into a pool of cool water.
That indoor skydiving looks really fun. I want to do that!
Thank you for showing me this😀
Love the so serious facial expression while you were in there, Doc. Haha
The reason I haven’t done indoor skydiving is because of how the guy in there never leaves people alone
Omg I love indoor sky diving!!!!!!
another reason why you might think of them like this is due to your camera, when your camera (and your eye to an extent) sees a raindrop it looks like a huge streek because the shutter speed (how long it takes for your camera to take a photo, and for how long the lens is open), because in that time between when the shutter opens and closes it will have traveld a significant distence, and that looks like a streek. this is why when i do cgi (and so do some pros) i actualy make rain drops realy streched out tear drop shapes, because that is how a camera would see it.
That "Stay curious" though ahah
4:00 when you've been falling in a videogame for so long your character starts glitching
Never thought I would be so amazed by a raindrop. 👀

Welcome to another episode of "where quarantine got me"
when TH-cam recommend the video to you
The wind tunnel scenes reminded me of the scene in Willy Wonka where Charlie and his grandfather partake of the Fizzy Lifting Drinks and float upwards where the fan blades await their ultimate doom before belching and slowly returning to earth.
As a kid I thought they would be like spear shapes because the air going around it was squishing it's sides inwards as it travelled past, not once did I ever take the tear drop shape seriously, but now I don't even know if they're spear shapes anymore because you're telling me they're actually beanbag that's not yet been sat on shaped!
I didn't know about raindrops ripping themselves apart in mid-air! Now that I've realised it, it seems obvious that that would happen as they collect and get bigger, but it's still so awesome to see it happen!
I LOVE the Dr. Strangelove visual reference. Well done!
I went to that place before. It’s super fun.
I wish I could go back to kindergarden, draw this shape, and when the teacher tells me off I explain this then tell the 32 year old they were just corrected by a 5 year old on physics.
