That fabled tear-shaped raindrop may make for a good color-by-numbers, but the truth is that raindrops are a lot more complicated and far less pointy.

@@misterhat5823 it's a way for viewers to show their support for SciShow's free videos lmao no one's forcing you to buy it
@@misterhat5823 I would have gotten it... but it has lgbt stem day... like I don't care what genitals u like... I will hire u if ur good at math and science. Virtue signaling
"The Shape of Water" could make a really cool calendar!
@@misterhat5823 yeah, it's a for-profit company, of course they're trying to earn money.
@VladLen yeah, it's a for-profit company that also receives support through fan donations like Patreon. If your intent is to buy a calendar, then you most certainly don't need to get their expensive calendar. But if you wanted to support the channel, the calendar is a bonus.
I think the tear drop shape comes more from seeing water streaking down windows during rainfall. And like the snowflake shape that doesn't really exist, it just became the come representation for rain.
I’d argue it comes from tears. 😂
@@franimal86 but the sad emojis tears are shaped like straws lol 😭
the snowflake shape does exist, just not as the 8-fold symmetrical origami ones
Tear-drop shape is also just useful as a graphical illustration.
However, it's known for centuries that liquid droplets falling from a considerable height become spherical and that knowledge has been applied to hot metals & glass cooling as they fall to form everything from lead-shot & marbles, to cannon-balls!
@@1224chrisng, snowflakes are hex shaped...
I’d like to point out raindrops in anime tend to be straight lines, signifying movement of a drop through space quicker than the human eye can perceive it. It’s like impressionist rain drops
Or more accurately, a picture of a raindrop with long exposure heheh
Have you seen Japanese classic woodblock prints (by Hiroshige for instance) showing rain? It is as you describe already, black lines. And it is beautiful.
Ah, a fellow man of culture, I see
It goes "SHAAAAA"
@@Chrishelmuth1978 aha
Michael's evolution into a metal demi-god is going well. And he looks newly buffed.
I am pleased. Carry on with the science-ing.
hehe yeah was thinking the same, keep the hair ...I miss mine, shaved myself bold just out of curiosity, but am now in the slow process of growing it back 😓
@@blehsarr5165 bald and bold
IK RIGHT he looks amazing with that hair!!!
@@yuridc1780 hehe yeah got bold and went bald 😅
Native hair and American fat heavy body …
Tear-drop shape has always been a very useful as a graphical illustration so it'll continue to be used so as not to be confused with spherical objects like balls.

prince rupert drops are clearly drop shaped, explain bozo
@@theendofthestart8179 "From a considerable height." The drops have to be moving fast before they solidify

@@sianmilne4879 are you telling me that rain doesnt fall from a considerable height?

I've been living in the desert for too long. I miss rain so much i could cry.

You have such gorgeous long hair! I remember your short 'do with the bleach streak and that was cool. but long hair looks fantastic on you!
"We been through every kind of rain there is. Little bitty stingin' rain... and big ol' fat rain. Rain that flew in sideways. And sometimes rain even seemed to come straight up from underneath."
This is one of those fun facts I knew since when I was young and completely forgot about it for years.
Watched scishow for years. This is my favorite version of Michael
I didn't know an octopus had three hearts, but it didn't surprise me too much because knowing how tractors work with fluid dynamics and spiders also, it would make sense that they would need three pumps to move all those tentacles.
Fluid Dynamics and Spiders? that's an interesting story.
@@1224chrisng you didn't know spiders 🕷 move like a loader does?
Scientists have been able to make them move like that for years now.
The more you know!
Octopodes don't have tentacles.
@@TheRealSkeletor Noted. 🤔. I'm not a marine biologist, I'm a scientist damnit! 😆
Yeah. That's why if the tarantulas get thirsty, they might fall into a feedback cycle where they can't hunt because they don't have enough hydraulic pressure to move around and because they can't hunt they can't replenish their body fluids.
Ah yes I do INFACT need *Pie* this upload helped me use my pecan pie to look at rain drops, but sadly my pie didn't last long.
Always great to see Michael! Wonderful episode as always!
You've actually answered a question I've had for a very long time. I had wondered why rain came in drops instead of one (or many) massive globes, and I'd never thought to consider air resistance.
it's also the same reason why small meteoroids and asteroids never strikes earth; they fall at such a speed, they burn away against the atmosphere. other stars like our moon, doesn't have an at atmosphere that's why it can get hit; and also the reason why the crater don't disappear, the lack of atmosphere preserves it in the vacuum of space.
Prof Mike Merrifield (of 60 Symbols) said that bigger drops flatten at the bottom into the hamburger bun shape, as Michael described.
They then become concave at the base, then they trap air and inflate like a balloon until they pop, into many smaller droplets.
That cycle of droplets coalescing and popping continues until they hit the ground.
Bro, your hair is epic.
Yah!! I saw a vid of him from years ago with a crew cut and this is better for his face
Hi, thank you for the science, also thank you for your amazing hair
Seriously every time I check in with scishow his hair gets prettier
The "tear" drop shape comes from, well, tears of course! Tears fall down the surface of the face and the pores and slight contours of skin and or hair combined with friction drag out the trailing edge of the droplet making a "tail" thus making a tear drop shape. Tears also are a bit more complex in that they are also made up of salts and oils as well as water.
Thank You. I was confused by the entire premise of the video since like you said thats a tear drop not a rain drop.
Next you'll tell me the hearts people draw don't look like a real heart.
They may not look raindrop shaped, but they do keep falling on my head.
Caus that’s a tear drop
Great content!! Bring back the Quiz Show!!!
I think I found that elusive cartoon teardrop shape. At 3:52, in the third panel, you can see the drop with a round base and a pointy top. It doesn't last, but it looks like it is there for a fraction of a second.
I saw that too
I like that the reason Rain drops aren't that pointy shape is the same reason faucet drips are: surface tension
We need pi for everything round, and we need pie because it tastes so damn good
Forrest Gump studied rain as well: "We been through every kind of rain there is. Little bitty stingin' rain... and big ol' fat rain. Rain that flew in sideways. And sometimes rain even seemed to come straight up from underneath. Shoot, it even rained at night... "
Michael: We need Pi!
My brain: I need pie...
i thought we all knew this and never once thought that they were "teardrop" shaped. i was under the impression the general concensus was that the top of the teardrop shape we see represented was an illustration of the drag force of a falling liquid or fluid object
It's always represented movement, falling down, to me
Love vids like this
the fact that the Pi calender isnt round surprises me lol that would have been perfect lol
haven't checked sci show in a while and DUDE WOW YOUR HAIR I'M SO JEALOUS 😍
Okay but when you throw a baseball it doesn't have little lines behind it indicating "whoosh! Really fast!' like in a cartoon either. It's an exaggerated reflection of the round drop moving downwards quickly.
oh my GOD Michaels hair looks AMAZING!!!!
I love the universe! So amazing!
30 years ago, in Jr. high my son got into an argument with his science teacher who claimed the air resistance tear drop shape of a raindrop was the most aerodynamic. My son argued that raindrops did not have the most aerodynamic shape because if they did they would kill you. Luckily, he was right.
Doesn't blowing a bunch of air back at the falling drops change the shape of the drop. Logically if the drop is no longer falling as fast I'd expect it to not have a tail. I'm sure they accounted for this somehow, but would have been nice to know how.
I imagine it's to replicate air resistance
This man’s voice is so calming. I could fall asleep just hearing him say “I hate you”.
Raindrops are fascinating! its fluid dynamics in freefall!
Ive seen Raindrops falling, from big blobs tumbeling down to hairs of water blowing in the wind, i bet the "aerodynamic" ones are out there somewhere 😅
All those memories lost in time, like tears in rain…….
The information in this video is great, but it cannot compare to the glory that is Michael's hair! Seriously, it looks so soft and shiny, and I am so jealous!!!! We need a science of Michael's hair video!
Why do I hear a weird faint sound at 4:08? It was so subtle I thought it was my headphone capturing static but it always appears in the same part of the video, kind of like a individual pulse sound.
Wait, so what influence do the shapes of raindrops have on the weather? Did I completely miss that explanation?
I love the night elf look!
nice little nod to the film The Shape of Water, very sly 😉
This man's hair journey has been lovely to watch 😍
Raindrops keep fallin' on my head
I like how Misty’s Cascade Badge is the thumbnail.
Lots to learn, like how to secure funding for fun projects like this!
I would never have guess this video would be so dang interesting. :)
so if a cartoon used accurate rain, would we notice?
Love "The Shape of Water" reference at the end. Or at least the way he said it makes it sound like a reference.
When a big storm comes I've seen the really big drops (you know they are big because when the street is dry you can see the way bigger wet circle they leave on impact) look like rods mid air, like thick pencils. But I only see that as I said when the drops are huge.
My brain RN 🤯🤯🤯
I definitely need pie.
Man... now I want pie.
loving his hair
I'm growing my hair out to that length again, and he's always improving his speech (not that he had a problem to begin with) he sounds good
Props for calling out The Shape of Water!
Raindrop bingo could be a cool band name
I recently discovered that a teardrop shaped loop, on a roller coaster, is much easier for a person to handle (the G-forces) than a circle. Very interesting.
I hadn´t realized that the surface tension of water is that strong.
Also: reaching god level hair!! Any guys out there willing to follow the example?
Wow. Except for their glaring differences, water and mercury are a lot alike. That made sense a minute ago. I mean.. Their viscosities and cohesive properties seem like barbs of the same feather. That’s slightly better.
Flagging this video as needing (not just auto-generated) subtitles. Please help us hard of hearing and deaf folks access your content!! 🥰🤟🏻
Here's a question though - if it looks nothing like it, why did we illustrate it like that in the first place?
I imagine that it was because we modeled it after something way more viscous... or perhaps it was just for illustrative purposes?
I'm pretty sure the common raindrop/teardrop shape is more supposed to represent what water droplets look like running down a surface (like a window pane or someone's cheek) rather than water droplets free falling in the air.
0:43 Sheet Type Collision (c) is a pointy tipped rain drop shape
This video just reminded me of the really weird movie that came out a few years ago “The Shape of Water”
Very interesting
Should’ve waited to drop this on March 14th
The big drops having a flat surface makes sense and not just for suface tension reasons. If all y'all ever felt just one big sucker splat on you, you actually feel how big it is thanks to how much of it touches your skin when it lands. I get storms regularly when I wonder if it's small hail hitting the windows, but nope it's just big raindrops xD;
I love our good old solvent of life!
New channel idea: Scishow Rain
Water likes to stick together, so would a less cohesive liquid have a shape more similar to the teardrop?
Nope

“University of Toronto (UofT)”
Represent!
Wow, I never thought you would need pie to understand how rain works
"The Shape Of Water" - great movie ...
Three cheers for the universal solvent👍, especially when it falls like a miracle from the sky🌧
Michael your hair omg🤩🤩🤩❤️❤️❤️
Where can we submit ideas for new shows?
So would a non polar liquid make the classic droplet shape?
Also interesting is how viscosity and surface tension affects it (eg. mineral oil vs. acetone) or what is a liquid has more coherence than adherence (mercury)
We been through every kind of rain there is
Michael 😍😍😍
How cool is that!?😃
I do graphic novels, and I'm here trying to up my art-details game.
That hair, though. Fabulous.
Has there been any experiments on the various shapes of rain drop collisions in zero gravity?
Rain doesn't drop in zero gravity, and collisions aren't likely when there's nothing making them move. There's a video of water in zero gravity on the space station somewhere on CZcams, I think it just globbed together.
Awesome job pronouncing Toronto properly. I’m from Toronto. Most people who are not from Toronto incorrectly pronounce it toe-ron-toe.
Oh huh, interesting. Toe-ron-toe sounds Midwest to me, vs how I've always heard it here in the PNW as Tor-aunt-oh
Just listen to the way Kevin Hart (and practically everyone else) pronounces it in the film, The Man from Toronto. I think I only heard one guy in that film say it like people from Toronto do.
I've always said it tuh ron toe
So it's supposed to be pronounced "toh-ROHN-oh" then? Timestamp @ 3:36 for anyone else wondering.
@@iprobablyforgotsomething yes
Tell me if my lifelong assumption is true - I've always assumed that the technical definition of a drop, when referring to weight, is the moment a droplet of water is finally heavy enough (has accumulated enough water) to fall.
omg it's Michael :D
Fascinating video, of course, but how has Michael's hair grown so long so fast?!
Shape of a water balloon being filled up vs being in flight. Pretty self evident.
Maybe the neck is what it looked like when that giant rock hit the earth that gave us the moon
Holy molly!. Nice hair!
Be still my beating heart! Michael you're looking incredible with those luscious locks 😍😍😍
Has anyone worked at comparing the colliding raindrop shapes with the shapes created by colliding galaxies? Broadly similar to my eye, but I'm not whatever kind of scientist studies whatever that kind of science is...
How did the stereotypical teardrop shape become so popular if it is not accurate?
How about the heart shape?
It is accurate, for a tear drop coming out of your eye
@@franimal86 Nope,,, it is Not!
Unless you are a Cartoon?! Or Emoji....😅
Wish I was a rain droplet. Imagine falling down toward the ground and then *splat* it's over.
We need a video proving humans don't actually look like 5 lines and a circle attached on top, sometimes with 2 fancy circles and additional line inside it
japan and Philippines storms here. southeast to north.
Now I so much need an apple pie. 🥰
