If you think I'm going to walk backwards infront of the whole campus to prevent my coffee from spilling, you are absolutely correct.
when did stefan get ripped
Both of them have the same doofus face in the thumbnail.
Awwwwwwwwwwwwww.😁
Also Dr Shini is awesome.
I'd dare to say she's stunningly gorgeous.
@@IljaSara I agree
Aside from her great looks - I’d wager from her crash course and broadcast appearances that she has a dream-unicorn-level personality cause to be able to have dinner or brunch with her, time would literally jump. Like a inverse time dilation.
10:20 The way you phrased the question by including "less than," technically, means that A, B, and C are correct. If it is less than 1 in 100,000 it is also less than 1 in 10,000 and 1 in 1000.
You would be correct, if not for the fact that the actual question happened before the 10-minute mark.
Dr. Shini is the real winner for having that sweet sweet accent.
6:40 Put a lid on the coffee.
We over here playing checkers, this guy's playing chess
For question 2 I have a better method learned when I was a student : do not look at what you're holding (also true for glasses and such), because the correction you'll involuntarily make to correct the wobble will actually increase it, where simple steadiness and looking upfront will do a better job at keeping the content steady. Plus you're actually looking where you are going, which is probably better than walking backwards.
My manager overheard me talking about wanting to design a gyro-stabilized coffee mug so I didn't spill it on my way back to my desk. She told me she worked as a cocktail waitress when she was in college and learned to not look at what she was carrying in order to prevent spills, so she agrees with you.
I tried that and spilled it even worse. Go figure. I guess I'm just doomed.
I always do the claw technique if a cup is too full. (Hold from above)
👍👌
I use it as well for grabbing chips/crisps
I don't look at the cup. Somehow focusing on the surface level in the cup makes you overcompensate and induce a bigger oscillation. If you focus out at the real horizon you dampen the oscillation. (Works for me anyway.)
SciShow Quiz show! It truly is the best quiz show on SciShow!
I think it's funny that Erin and Evan both have "E" names, and Stefan's shirt had a logo with opposing Es.
That was not on purpose, but awesome!
@@SciShow Engineering Explained.
Walk with a spoon in your mug of coffee. The spoon breaks up the waves, keeping them from building.
I just found scishow quiz show and I've already watched all of them. We need more!
This was actually really informative and fun. Good stuff.
Omg Shini is the business... Just stating fax.
I love that scishow now use the metric system more in their videos
Modern fighter jets also use inherently unstable designs in order to increase maneuverability. Without the aid of modern fly-by-wire systems pilots would be unable to keep these planes in the air. The fish's small fins and its brain act as control surfaces and the fly-by-wire system. Or in this case swim-by-neurons :)
If you create a ring of poop around you, maybe you and your eggs are less likely to be approached by predators not in the sky?lol
is it me or is that an engineering explained t-shirt?!
awesome :D
@@orbitalspider they sell them true there web store (DFTBA)
so it's a nice thing to do.
That was entertaining. Good job guys.
0:11 - Actually, SciShow Quiz Show is only the second best quiz-show on SciShow.
4:44 - There was a second part to that; first tilt the cup 35°, _then tilt it back_ .
7:12 - Yes, yes it is. Fluids come in a variety of viscositis, including very high.
14:16 - Alex Dainis just did a video on the fly-in-the-wine thing last week: th-cam.com/video/WPiLA22-QU4/w-d-xo.html
I like that format a lot! Because I got everything wrong I can now actually remember the right information! Very entertaining! Thank you!
I love this quiz. Thanks scishow!
*_I see the word 'Aliens', I click_*
Someone tag Engineering Explained
Conspiracy Theory: the ‘secret’ Sci-Show swag is the shirt Stephen is wearing
Omg Dr. Shini!!!! I've been a fan of hers for ages! I didn't know she did crash course engineering
"Luckily, the penguins have a solution: they can projectile poop."
😊
But when all those flies on Titan overpopulate, will one among them present a solution: kill half and call it mercy?
I'm waiting to see what kind of higher life form they evolve into by the time we get there. Oh, wait. I'll be long gone by then. Oh, well.
Can we have Michael on Scishow TANGENTS?????
How do they manage to form sentences around Shini? She's too powerful, I'd be stutter city.
I on the other hand would be able to form many sentences. One of those being. May I treat you to lunch?
Loved this, getting to guess the awsers was fun
Michael's Magnificient Hair is back! 👨🏻🎤
2:10 Scientists were going to design a car based on the shape of the boxfish?
That's thinking outside the box.
@@AxxLAfriku OMG it's AxxL!!!! You are the TH-cam Megastar and biggest star of this generation. Also known as the Ugliest Human Worldwide and G.O.A.T.
I am honored to have you reply to my little comment ;)
Actually, it's thinking INSIDE the box :)
Your jokes are so cringey
I appreciate your replies, Sir. I prefer yours over the dirty metal computer dude.
@@BlackWolf42- LOL "dirty metal computer dude" that's hilarious ^_^
Shini: "By the way, I kinda feel the pressure now!"
Me (thinking it): "That's alright, Shini, just go with the flow..."
...And so, the Battle of (more-or-less unintentional) 'Fluid Dynamics' Puns began!...
I'm glad you guys managed to work poop into this.
The box fish would be a good design for space ships
That tie is everything.
This is great. Try doing a Jeopardy!-style quiz contest.
8:33 "exactually" >.
These are my favorite
5:20 I just have a cup that's about twice the size it needs to be, and I've never spilled my coffee
u guys should post more of this kinda stuff
For some reason, the boxfish question for me just sent my thoughts out to space. What is the easiest shape to create a probe to buzz around a station? A box. So of course it was extremely maneuverable. I have no idea how that works in fuild, but I guess they use they're fins very effieciently.
13:07 Just ask The Talking Heads if there's water flowing underground - I'm pretty sure they'll have an answer for you.
Hey SciShow! I am not sure how to submit an idea for the show, since I don't have Facebook, Twitter, Instagram, or anything like that, but I read the most interesting story today about how there are not JUST Fraternal Twins and Identical Twins. There is an incredibly rare type that is referred to as, "Semi-Identical", and I was wondering if you could do a video on that? I thought maybe your viewers would find it fascinating, as well! Keep up the great work! ~Susan
Thanks Susan! We'll add this to our pitch board!
@@SciShow Cool! I believe the term they used for the "Semi-Identical" twins was sesquizygotic. Thanks again!
holding a cup from the top works every time, i do it always
We will find life on Mars. Because we sent it there.
"Orange light?"
"That is incorrect."
Dr. Somara, stop wringing in first!
Dr Shini is awesome!
For spilling coffee problem, I would try building a floating box, like half a cube that holds the mug tightly, with 4 strings attacked to corners connected at a single point on top, and a strings that connects that point to a handle or ring that you can hold...
Tilting the front of the coffee cup slightly downward relative to walking stability/speed with dimensional analyses and derivative theorems of Pythagorean's theorem you could calculate exactly the degree at which you should tilt your coffee cup in order to completely avoid spillage assuming you haven't filled your coffee cup all the way to the brim. =)
Excellent set of questions and a good entertainment, keep posting this series
Brilliant people!
The fluids are indeed dynamic
Notice me
They are viscous.
@@carcinogenicthalidomide3057 more like feceous
The trick not to spill coffee is not to look at it and not try to compensate. The high frequency comes mostly from trying to hold it stable and the high muscle tonus resulting.. Relax and just walk; way less sloshing that way.
collab of the century
Thank You!
Who else plays along with them? I got 1700 before the winning round then bet 1100 of my points on C and lost lmao
To be fair I took a pretty long pause for some of the questions so that kinda gave me an unfair advantage xD
Hahaha same, but I had 1500 and bet 500 on A.
OMG, why have I never even thought about playing along?!?
This is stupid why do i discover now i can play allong... im stupid
I do too, only without the scores.
The fluids in aliens?
Is it green?
no it's blue..... dabadee dabadie
Vex milk
If it is, the question remIns...is it Hank Green, or John Green?
My favorite show
what i do when i'm carrying a coffee mug is i put my thumb through the handle, and then use my four fingers to hold underneath it. that way, i have the most possible control over the tilt, because first of all i have joints for both tilt and roll axis, second of all, i have a tighter grip on it, and third, it just is far more comfortable to carry that way.
Alex Dainis did a video about a fly ruining your wine from the final round. It was probably available after this was filmed though..
I literally thought for about 5 seconds after they came back from commercial break that Hank had a giant lollipop and they just weren't going to talk about it. Then I realized it was the red part of the pen he was writing with.
Like a black hole that breaks my atoms apart,
Bright quasar whose jet of particles pierces my heart,
Without a doubt, deathly but smart;
Oliva Gordon, you are a piece of art.
I work in a factory where I walk past all kinds of forklifts and machinery when I return from break with my coffee. I'll have to give this walking backwards business a try! Just kidding.
1000 points to Stefan for the Engineering Explained t-shirt!
This is basically Science or Fiction from the Skeptic's Guide to the Universe podcast, except the participants on the SGU have to explain their reasoning for their answer. It's a great science podcast and I recommend everyone who watches SciShow to check it out. They've got 700+ episodes of science based content to listen to. It promotes Scientific Skepticism, which is a philosophy that basically says all empirical claims should be subjected to scientific scrutiny before being accepted. It's the best science podcast in the business, and it's been going for 14 years (15 on May 5th).
Ha! I knew the fly question because I watched a video about it by Alex Dainis. I wonder if someone else from the SciShow team did the same or if this was a total coincidence?
Hank's on a winning streak! first Sam "Hermitcrab" Schultz and now Dr. Shini ? wow, he's learnin'.
I agree with Hank that fruit fly pheromones wouldn't be smelly enough to waste a whole glass of tea. It won't kill or even harm you.
I always enjoy these "gameshow" types of shows.
Q1 boxfish are the aquatic equivalent of a fighter jet.
Q2 always the craw - th-cam.com/video/ftgAG3Vnif8/w-d-xo.html
Q3 always turn to look people directly in the eye
Q4 human contaminates everywhere!!
Fly's!Fly's!Fly's!Fly's!Fly's!Fly's!
9:39 finally pronouncing km properly! Yay
Man, I just love SciShow Quiz Show!
The real solution for not spilling your beverage is to allow the cup to pivot. The fluid and cup move as a solid body and it doesn't spill. Requires a slightly different holding technique but works for cups with and without a handle.
There actually was a Scishow video on the last question, wasn't it?
We still love you Shini! Too bad they didn't ask a question about curl (Del cross product Force Vector) in turbulent flows. ;)
Oh my God Dr shini is sweet and smart at the same time! 😭😭😂❤😂
Yaaaay! I really admire Dr. Shini!
Is it just me or is hank more energetic in this episode than previously
Didn’t Hank get asked this question during P4A in his quiz/being shocked punishment? Or am I making this up?
I’ve definitely heard that one before
Woohoo, Montana!
Soooo he opened by describing the strategy I generally use in life lol
I wasn't paying full attention and as they were introducing Dr. Somara I swear to got I I heard shitty and my head has never snapped down as fast as it just did 😂😂😂
'Tongue in cheek fluid dynamics', 'Maneuverable box'....some serious sexual undertones here.
I thought for sure that Shini would win this.
Spoilers!!!
Fruit flies on Titan... Wut.? Lmao Hank is me right there.
Anyone noticed Stephen is wearing merch from youtuber Engineering Explained
The Green Brothers shoukd compete against each other!
Clearly the solution to the coffee problem is to use mugs large enough that their resonant frequency is closer to 1-2 Hz.
I'm almost certain I've heard that walking faster also gets you out of the resonance range.
[whispered] mugs with anti slosh baffles
Oddly, not looking at your coffee as your walk, works wonders too.
Okay if you don't want to spill what is in your mug, you hold it with both hands around the rim. I actually do it with my finger tips and I keep my eyes on it, trying to make corrections as needed. I only ever spill when my headphone cable gets caught around the glass and I stand up suddenly. Or I'm stretching or turning with my arms out and smack something off my desk. Also don't over fill the container. Okay I'm done ranting.
Erin Mills is also a place in Canada. en.m.wikipedia.org/wiki/Erin_Mills
Everyone knows that aliens are made of green goo that can melt thick steel when their body was cut open
yellow not green
I want a scishow tie
To prevent coffee spilling, they forgot the classic solution: walk with a limp.
I paused before the penguin question to comment. Time 7.19; Penguins shoot poop 40cm of distance in a single push.
not after they've eaten chipotle
haven't even started yet and I know Hank's in big trouble this time :)
Haha, my thoughts exactly. First time I see her in a video, but she has that super smart vibe
Spoiler she lost
I was going to contest the assertion that Hank is the most famous author with the last name green in Missoula, Montana, but then I remembered John doesn't live in the same town as Hank.
