Quiz Show with Caitlin Hofmeister

[@saphruthven]

I now want to know what happened during the commercial break

[@MaxFrisch84]

Caitlin won by cuteness.

[@aidanadkins6895]

Stephan Chin always wears a red shirt. So could we call him the Crimson Chin?

[@ChaosWolfJoe]

+Aidan Adkins This is funny. I like this. Much good.

[@kisuetahamasaki9269]

Caitlyn is so adorable !!!!

[@workinghoustonian]

+Kisueta Hamasaki yea she is ^ ^

[@uglyweirdo1389]

Quite. I wonder if she likes picnics? I wonder if she would like to go on a picnic with meeeeeee.

[@qwertboyo]

These are so goofy and I love them, and never edit out anything it's perfect.

[@199NickYT]

During the commercial break, my guess was the good ol' "How did Darth Vader know what Luke got him for Christmas?" Joke. Since Hank says "I felt his presents" just after you guys came back from the break!

[@griffinsmith8326]

I MUST KNOW WHAT HAPPENED IN THE COMMERCIAL BREAK.

[@TheRealSkeletor]

Two things: 2:19 Someone please make that a gif. 5:22 "We're going to talk about size" *Hank covers himself*

[@Mockturtlesoup1]

lol. "next, we're gonna talk size..." (hank puts hands over his junk.)

[@Nolac00k-k5d]

6:29 best quote ever

[@13vatra]

You can get this tie! Not this tie, you can get a tie that looks like this. This one's MINE! That's just too perfect!

[@Crystalvampire66]

Ok. So I had an idea that needs to happen. An all game show youtube channel with Michael hosting most, if not all of the shows. He'd be perfect for it.

[@Ardithel]

This is by far my favourite Scishow Quizshow so far, for reasons :) Incidentally, I would have guessed off-hand that the contestants are the people on whose behalf Hank and Caitlin are playing (ie: Justin Eltoft, Sean McLennan & Jason Archibald), but you raise an interesting point.

[@Ardithel]

Not sure why I said "you" as if Michael is ever going to read this XD

[@Omilliyo]

Michael has gotten better at hosting.

[@billymoore1970]

Our sun is white. If it were yellow, snow would be yellow. And how would the kids write their names in the snow then?

[@nav6maini]

Wait you are just kidding right

[@effortless35]

Gabriel Tzukishiro Nah, it does look whitish from space. The atmosphere scatters a lot of the blue making it look yellow or even red during sunset.

[@jessehe1671]

The Sun is actually white, if that's what you were wondering, but the reasoning behind this comment is... shaky, to say the least.

[@effortless35]

Well, it's white and it's a star so... But yeah, not a white star in the BAFGKM sense.

[@nav6maini]

It's a ball of fire FIRE Red and orange fire RED AND ORANGE FIRE

[@SynergyhubOrg-WA]

Enjoyed the contest for sure. Like the low tech and casual approach to it. Now a pop quiz: Is the "buzzer" a) A major chain store's "Easy" button spray painted white b) A battery powered closet light "as seen on TV" c) A dead prop.. the buzzer is added in Post Production

[@manos6590]

Please never EVER attempt to "correct" or "fix" all that silliness, it's awesome!

[@jakestein8588]

There are sharks that don't need to buccal pump in order to breathe while stationary. Some sharks have spiracles which act as nostrils that allow them to breathe while still.

[@jbaketkd]

Smart people are the coolest! I would love to hang out with the Sci Show cast

[@TacoSt8]

caitlin is so cutee n.n

[@n3tdh]

+Omar St i think a major part of her beauty is her perky happy energy. she seems like the friend you want to hang out with because she could eliminate your sorrows with a mere smile

[@jasminaquino6971]

Is this the first time Hank wins? Yayyyy "Hank. My name's Hank. My name's Hank Green."

[@JiffyPopLuv]

You guys are my favorite people

[@Arikayx13]

More Caitlin Hofmeister on Sci show space!

[@Dr7Mac]

Hello Scishow, I think one buzzer per contestant might be better.

[@joshuavanmechelen8536]

Ok... great idea to spice up the channel... here's what you should add: cheesy game show back ground music ( intense for the final round), more questions in same amount of video time, during commercial break you could "sell" some fake science-based thing (old invention or futuristic new one perhaps?). Totally thought that Sci-Showdown should be the name of the game show. Please consider these suggestions and I love your channels!

[@MrHSX]

What happened during the break?! I must know!

[@blazebluebass]

10:20 Now I want Michael's tie!!! I do not know who came up with this SciShow Quiz Show idea but it is absolutely great!

[@meebond]

I am interested in Caitlin Hofmeister!

[@aussiebaka4588]

How quickly Hank's hands moved to cover his junk as soon as "size" was mentioned! Oh gosh I got a giggle! XD

[@SarahZhou]

the meh michael made :) Lol

[@rhaegartargaryen9559]

Michael is hilarious, lol. I love his channel!

[@mickeymoose636]

Rhaegar Targaryen He has a channel???

[@michaelaranda]

Nicholas Audinet He sure does! Several, actually! Artsy stuff? Go here: kzbin.info Daily Vlogs? Try here, instead: kzbin.info Or both. Probably both.

[@KyleJustRuns]

1:36 was that a Freudian Slip there Caitlin? Lmao Hank dodged that one real quick with "celeries?" 🤣😂🤣

[@cm374787]

So many Justins get picked for the quiz show. I like it. I like to pretend Hank is playing for me. Hank is my spirit animal.

[@Blackterror92]

Nice show, make more of these

[@extrams0]

This had me confused for a while, but the most important thing is what they don't say in this movie: in that an ext. combusion engine is a HEAT ENGINE. it's not "any" energy that's applied to the working flued, but heat energy. - rocket: uses volume increase of combustion (= internal combustion) - nuke plant: uses volume increase of heat (= external "combustion". Not combustion but the peeps who named it were to laisy to update the name) - hydro-power: uses movement of of falling/running water (gravity) - battery: chemical energy The last two are neither internal nor external combusion engines. Likewise, If you take a nuke plant, and instead of heating the water to steam, you use a battery to convert water to hydrogen gas (so, exact same principle, but use electricity instead of heat), it's no longer a heat engine.and thus not a ext. combust engine.

[@casschambre1974]

I really enjoy the quiz shows. Always funny. Always informative. Keep it up!

[@TheMunich2011]

You should try and get your brother in to do the quiz show

[@nadiact-ie5hy]

That would be a fair fight!

[@MelvinArthurMurray]

That would be intense Lol

[@walter081095]

Hey Hank is using a gold and white shirt right?

[@taken_over3416]

You just made me remember things from a life past

[@seanmclennan8535]

Michael! It's McLe*nn*an not McLe*ll*an! :(

[@skyfinity9199]

Sorry you didn't win. If it's any consolation, you still seem pretty interesting. :)

[@michaelaranda]

Sorry. :( My only excuse is that the print on the back of the cards is tiny.

[@seanmclennan8535]

***** I forgive you. :) AND I'm giving you another chance. :) Don't mess it up next time!

[@seanmclennan8535]

***** Thank you!

[@ljmastertroll]

What's the exchange rate on SciShow bucks these days?

[@jezzalike22]

2 celeries to a buck I believe

[@Galakyllz]

jezzalike22 I've heard the exchange rate for carrots is far worse...

[@ssppeellll]

It's small potatoes.

[@SlimThrull]

ssppeellll * rimshot *

[@csdn4483]

No answer is correct for the combustion question because combustion requires a fuel and an *oxidizer*. Nuclear does not oxidize, but fissions (or some day, fusions) an atom that becomes two or more atoms plus a few neutrons, some gamma rays, and some neutrinos. So that answer for the final question are all wrong. So, while yes, the fuel does act on the working fluid, it is not doing it through combustion.

[@Pyrex92]

I wish they had these more often. I love them!

[@chrislamar8646]

You guys need another buzzer btw

[@supernovadiary]

Could you do a video on the science of quicksand? Thanks :)

[@BamboLord]

man, in regular scishow episodes you can't tell how much of a hunch back hank has

[@CallMePapa209]

So true

[@atomicdeath10]

I'd like to actually play!

[@Adharaaa]

There needs to be an episode of this where Michael is a contestant and Hank is the host.

[@camembert101]

These people are just fun to watch :)

[@BryanSeigneur0]

I have an engineering core (comp. sci. degree) and I have learned so much astrophysics from Caitlyn. She's really good at transmitting information she doesn't know the backstory on between people who know the backstory, which is a special power of communication. lol but seriously

[@blazebluebass]

The beginning cracked me up. Good job! =D

[@HeinzP100]

I love this quiz show. Where else can nerds be nerdy in a nerdy sort of way?

[@ab6852]

I disagree with the answer to the final questions. There is no 'combustion' in a nuclear reaction.

[@ghuegel]

You're totally right. The nuclear power plant is analogous to an external combustion engine in that the nuclear reaction is used to heat water to drive turbines, but combustion is a chemical process, not a nuclear one.

[@gephc4]

That's exactly what I thought! If splitting atoms counts as combustion, so does water falling down a hill. This one was a tie. :)

[@AlexanderPavel]

It has nothing to do with chemical combustion though. Listen to the definitions again. A combustion engine uses a fluid to do work and doesn't necessarily need a chemical combustion.

[@jahlaydominguez5761]

The definition of an 'external combustion' engine as said at 8:53 - energy is applied to the working fluid from some outside force. Even though combustion is in the name, it does not have to have 'combustion' to be an external combustion engine by this definition, so nuclear power plants do in fact use an external combustion engine.

[@jahlaydominguez5761]

Geph C Its true that the water is a working fluid in a hydroelectric dam, but since humans are not actively putting energy into the fluid (except by building and maintaining the dam, which doesn't count) it can not be an external combustion engine.

[@DOMin8r1992]

I love these videos! Thanks

[@anaraug]

I liked the part where they answered quiz questions.

[@seanmarshall8713]

Caitlin, why don't you have a twitter.

[@LennyLenward]

Yay Sean and....... Archibald....

[@LimeGreenCutie7]

SciShow Celeries. I love it.

[@leemurdock5222]

Caitlin - my favorite SciShow Space host!

[@ThePlayfarer]

This show is always so awkward, but I love it anyway. xD

[@IvannaperezElkIP123]

Man, Michael's hair is so cool!

[@Neumah]

SciShow, you should do a segment on human hearing and how it relates to the audio engineering terms Peak and RMS levels, and then go ahead and make use of them correctly in your videos. Actually, snarkiness aside, that might be something the viewers might find interesting, like "why is the commercials on TV or youtube always much louder than the rest of the content?"

[@RadicalRatapus]

next week can we play for his tie?

[@StephenRoseDuo]

I didn't know Nuclear power plants use combustion... I always thought it was radioactive decay. None of the above was the best answer

[@devins7457]

They use the decay to heat water that produces steam that turns turbines that creates energy that powers stuff...

[@Mc_Vomit]

External vs internal combustion has nothing to do with an actual combustion reaction. As they said in the video, it's about whether the fuel is also the fluid that's doing work. Internal, energy comes from the working fluid. External, energy comes for some external source to the working fluid. So for an SFR, the fuel is being pushed out of the rocket and doing the work. In a hydroelectric dam, the water is the "fuel" and is also doing the work. In a fuel cell, the fuel is again doing the work and producing the energy. However, in a nuclear power plant, the fuel is not the fluid doing the work. The fuel is radioactive material, but it gives it's energy(from decay) to steam, which is the fluid doing the work. The key hint to the question was the example of a steam engine, since a nuclear power plant uses steam to spin its turbines.

[@8happyperson]

***** You explained it the best, thank you :)

[@jahlaydominguez5761]

The definition of an 'external combustion' engine as said at 8:53 - energy is applied to the working fluid from some outside force. Even though combustion is in the name, it does not have to have 'combustion' to be an external combustion engine by this definition, so nuclear power plants do in fact use an external combustion engine.

[@Mc_Vomit]

Stephen Rose I think you miss heard the question. The question was "Which of these devices uses external combustion?" You're correct that nuclear power does not use internal combustion, it uses external which is why it was the correct answer.

[@sharksgrr]

this show needs to happen more often, because it's both incredibly funny and interesting.

[@David-ld3ts]

I'm pretty interested in hank right now...

[@jimstilling733]

Please bring back the quiz

[@ligitmuffin]

I'm a hetero male... but GOD DAMN MICHEAL IS A SEXY BEAST. That is all.

[@krupajoekrupa]

nuclear power plants generate electricity by using heat from the reaction to boil water which spins turbines. The answer was basically given when the steam engine was used as an example.

[@ominousblackcat]

Just watched all the Quiz Shows. So funny, and I still feel like I learned things

[@kea7119]

Hank is just awesome. XD

[@kevind814]

Y'all need to get an extra buzzer; it will be much easier to tell which buzzer goes off first.

[@squeezemyparticiple]

When I saw the shirt Stephen was wearing, I immediately thought "HERE COMES...THE CRIMSON CHIN!!"

[@Twitchi]

And welcome to "Can you hit the button quicker than hank can?"!!!!!!

[@blackburn3r]

what happened in the commercial break.

[@alixc940]

I have the same glasses as you, Hank!

[@jlew92xx]

I have a question about the last question... Did you guys consider the "external combustion" the core, the heat source??? That's fission not a combustion....

[@AlleyBetwixt]

The nuclear donut plant made me think of The Simpsons.

[@Julika7]

How do I find the pictures you're using? Like the shark egg case by "Xtylee"? Haven't you once have a sheet of paper for the credits?

[@everestfalls]

thanks for making me smarter everyday.

[@riaupreti4725]

Does the celery come before the number or after? (important questions)

[@HALLish-bl3bm]

Combustion = Nuclear? I get that you where differentiating between working fluid and fuel, but I have an issue with the wording.

[@jahlaydominguez5761]

The definition of an 'external combustion' engine as said at 8:53 - energy is applied to the working fluid from some outside force. Even though combustion is in the name, it does not have to have 'combustion' to be an external combustion engine by this definition, so nuclear power plants do in fact use an external combustion engine. Its true that the water is a working fluid in a hydroelectric dam, but since humans are not actively putting energy into the fluid (except by building and maintaining the dam, which doesn't count) it can not be an external combustion engine.

[@TheHuesSciTech]

+Jahlay Dominguez Sure, *if* that were the definition, you'd be right. But it's so not -- wikipedia, and every other source I've looked at, says that an external combustion engine must involve combustion, defined as burning fuel with an oxidiser.

[@michaelmathes7162]

I love SciShow

[@TripzHD]

Make some more! -So great guys! :)

[@davidsmith-uq7fr]

I have a huge crush on Caitlin.

[@junkbot2.1]

i wanna know what happened during that commercial break!!!

[@ZMACATTACK808]

Now I specifically want Michael's tie.

[@BPBland]

There was a little explanation for all of the answers except for the final one. I know that answer but some people might like to hear it.

[@ryanburnsed5690]

They didn't say why nuclear was the correct answer, why is that? I could have sworn it was hydroelectric dams! Thanks for what you do guys. :)

[@lauren2576]

And now I understand why Michael said this was the rockiest one they'd filmed. Haha

[@zachariahz.3494]

Does SciShow do live shows? Because that would be awesome.

[@Videogamefan1992]

I was smiling during the whole video. So funny!

[@DanielaSerodio]

For a second there Michael was channelling the Old Spice guy. "You can get a tie that looks like my tie"

[@RocketBurnsAnimator]

I mistook the thumbnail as Hank getting married to the lass

[@MCshadow21]

The crew was extra giggly today

[@georgiamorse6233]

When he was reading the last green was like mmmm (most likely thinking: this a total turn on) I'm like what r u doin hank?!

[@cruznunez9981]

Happens with tiger sharks too, I read once in a book. Don't blame me if that's wrong. The book said there are two babies born in the shark, and they fight until only one is left.

[@HistoryNerd808]

It is. They give birth to 2 baby sharks but they're in separate ovaries so that they don't kill each other. The young in each ovary though have a fight to the death.

[@ohbbyilikeitrawr]

I really like hanks shirt!

[@chrislamar8646]

Wow, seven minutes? Man, that's a new record for me

[@markkeen3129]

Did anyone else get a youtube ad at 8:02 cause I got one about dairy milk.

[@aztec999999]

I love these

[@mattdangerg]

Why are there never any commercials!
