A Pure and Restful Quiz Show | SciShow Quiz Show

[Music] hello and welcome to scishow quiz show the only quiz show where they pull in writers as last-minute host yeah I'm your host sorry Riley and today's contestants are Hank green one-fourth of the amazing new science podcast that's not for children scishow tangents sara is also on tangents yeah we got half of us here well 2/3 will 3/4 if you count the one that's ally yeah guest host and Sam's right there on tangents is great all the way from the UK we have the evolutionary biologist PhD and our friend Sally LePage hello we're very excited to have her I'm gonna lose you say this I don't know I think I'm prone to overthinking the question I lose a lot okay so thank you to some of our amazing supporters on patreon we've chosen two of you at random to win some prizes that Hank and Sally will earn for you who is it Hank will be competing on behalf of Amanda Piazza hello Amanda and Sally will be playing for Kelvin Dueck hi Calvin great name great name yeah Stefon show our players and audience what they can win where am I what's do wait a second I know what this is this is the prize Oh let's get into it our two contestants today Amanda and Kelvin will both have a chance to walk away with some prizes so I must remind you that these prizes do not have a cash value you can't just like walk into a pizza place and be like here's a pin give me a pizza everyone's gonna be taking home autographed cards from our final round and the winner gets the lovely I won scishow quiz show pin and exactly one bushel of scishow swag from dftba.com but wait there's more the loser of the show the one with the least points but also the one with the most heart will get the I lost scishow quiz show pin which just lets the world know that you're proud of who you are and the fact that you lost an internet game show and who wouldn't be all right good luck contestants game on I'll start you both off with a thousand points I mean often it is the better strategy if you get a question right you get 200 and if you get one wrong you'll lose 100 okay so you'll still stay pretty high no matter how you do I've gotten negative but you can't have negative points cuz that's an added rule now doesn't my card no you cannot have negative points yeah well I made it happen one time impressive it works really hard I didn't do the skill in itself no I'm managing sigmay I did actively work toward it and the comments were very insistent that we now we dock me future points yeah but then we didn't do that and in order of you submitting your thesis Sally yeah Congrats thank you all of the categories in today's quiz show are about pure and restful things oh that's good I'm so glad it's not about evolutionary about the history of people submitting theses yeah going wrong all about fruit flies but our actual first category is Meadows love useful one of the most beautiful parts of meadows are the wildflowers but they're more than just fun to look at over the years humans have also found dozens of medicinal uses for them but our ways of identifying which plants to use haven't always been reliable take one idea called the doctrine of signatures according to some scholars it is said that a plant is safe and useful if it meets what condition a it releases a dark liquid when crushed B it has a strong or bitter smell C it looks like the thing you're trying to treat or D it leaves a mark if you rub it on your skin unless AC it looks like the thing you're trying to treat cuz that sounds like the kind of messed up thing somebody would think yep it's C it looks like the thing you're trying to treat the idea behind this doctrine is that if a plant looks like the thing you're trying to treat then it's there to help you so if you find a plant like bloodroot which releases a red orange compound then it can probably help heal blood conditions or if you find one that looks like a brain like a shrivel II walnut that can probably help your head obviously though that's not exactly super scientific and some historians today actually argue that this doctrine was never used to find new medicines at all instead it was just a way to help remember which ones were safe a lot of these plants haven't been documented so there's a good chance we'll never know the full answer but one thing's for sure just because a plant looks helpful totally doesn't mean that it is question number two depending on the types of plants and the time of year you might also find caterpillars lurking in meadows besides being all cute and fuzzy it turns out that some of these critters are a little sensitive for example one type of caterpillar in peru doesn't like being yelled at which like save if you scream at it you'll trigger its defense mechanism so what does it do hey it screams back at you be it unfurls tentacles see it spits out a toxin or D it releases noxious gas oh that's none of the things I was thinking it might be ha ha okay first of all this I thought this minute was supposed to be relaxing now they're screaming I mean probably spits out a toxin to easy yeah yeah noxious gas it's not noxious you know the answer is B it unfurls tentacles it isn't totally clear why this caterpillar which is part of the pneumatic camp a genus unfurls its tentacles but scientists have a few ideas one researcher suggested it could help the insect blend in by unfurling its tentacles it could look more like a flower blowing in the breeze they could also keep the main part of the caterpillar from being eaten basically by increasing the chances that a predator would bite one of those limbs instead of the insects main body they could even be predator detectors there are little hairs at the end of each tentacle called CT which could be used to pick up vibrations from animals that make a lot of noise like birds or maybe it's all three whatever the answer is these caterpillars can be a lot of fun for the researchers who find them in 2015 when a few ecologist came across them in Peru they got to spend the next several hours of screaming at insects which is all you could ever hope for in a job really I'm not scared of that at all any one of you could unfurled tentacles at me and I'd be fine I feel like if you screamed and then someone raised their arms like wave them around would that be I think this around I know yeah so on to the next category while you're relaxing in a peaceful meadow why thing you might want to do is watch some clouds go by so these next questions are all about clouds if I put them from both sides now because of airplanes oh yeah the top and bottom they look something up and down and yet somehow constellations I still even today don't really know clouds at all mm-hmm well we'll test your knowledge do you know it so that they play in my batch it's Jenny Mitchell okay good that's great I enjoyed that back question three in 1883 the famous Krakatoa volcano erupted in Indonesia like other eruptions the spewed a bunch of ash into the air but what was unusual is that it also created a previously undocumented type of cloud which is probably not what you'd expect from a huge volcanic eruption what kind of cloud was it a a thick shelf cloud be around mammatus cloud see a wispy noctilucent cloud or D a UFO shaped lenticular cloud B and the Matis cloud I don't know why I feel like I know that it's not D and that's all I've got but I have to go I've focused not D now that would be really embarrassing let's just go with a no it's C okay d the answer is C wispy noctilucent clouds noctilucent clouds are some of the rarer clouds out there but they're also some of the most beautiful they're best seen around dawn or dusk and look like feathery translucent streaks across the sky thanks to recent studies we know they're normally spotted near the poles since they need really cold dry air to form but the first time someone recorded seeing them was after the violent Krakatoa eruption in the 1880s when the volcano erupted it launched dust and ash dozens of kilometers high so far into the atmosphere that the air was cool and dry enough for noctilucent clouds to form been water vapor condensed around that Ash and dust creating a bunch of these rare wispy clouds this probably wasn't first time noctilucent clouds formed on earth whether at the poles or from volcanoes but from what historians can tell this was almost definitely the first time someone documented seeing them question four like noctilucent clouds nucleus clouds also form high in the atmosphere and are best seen around sunrise or sunset but usually they're not good news and this time it has nothing to do with volcanoes why do sky watchers dread seeing them eh they're a sign a blizzard is coming be there a sign the temperature is about to drop see they're nearly invisible to planes so they're dangerous or D they damage the ozone layer I hope the idea of a dangerous cloud we didn't see it nothing it's like black ice in the sky plane skidded out I don't think it's that one I've maybe I should have left that one open but maybe or maybe I'm tricking you and it is maybe well luckily I don't think it's that one either okay Oh either a sign that a blizzard is coming it's d they damage the ozone layer make rias clouds are also called type 2 polar stratospheric clouds and they're not great for the ozone layer the layer of our atmosphere that protects against a ton of radiation chlorine-containing gases can cling to the particles of these clouds and then react with each other to eventually form single chlorine atoms these atoms are highly reactive and can tear apart thousands of molecules in the ozone layer before they're finally neutralized by something like nitrogen without the clouds these reactions can still happen but they tend to be less common there is a silver lining here though make rias clouds definitely aren't the worst thing for the ozone layer and things that are more dangerous like chlorofluorocarbon or CFC emissions have been much lower in the past few decades if it's very much like that game where there's a goat behind the door and you've got to pick the other door oh the money ha ha yes yeah you did it good job you got the points and right now Hank has 900 points not bad and Sally has a thousand points so we've got net negative but we're neutral change yeah that's good and with that our last category is about tea arguably one of the most relaxing beverages is this the point where I say is a Brit I don't really like to you know yesterday sounds just freaking hot water mixed with orange juice it's really good for sore throat so if you are presenting on camera I would highly recommend what did you call it hot orange I like that name is that a thing that people say no but you don't have squash here as in like cordial we call squash so orange squash is like orange cordial and you'll mix that with hot water I don't know what any of those words means like I suppose and it's shelf-stable and you just mix it dilute it down with water and then you have a drink okay and if you mix it with hot water it's what you usually haven't have a cold and hot squash is you have those sachets of cider powder you mix with hot cider powder yeah it's like you can get your hot chocolate powder your apple cider powder so imagine that but is a concentrated liquid instead of a powder right I'm super into calling packets of kool-aid sachets now mm-hmm do you know no because it's way too fancy okay so with all that in mind instead of the questions being about tea they're about something that starts with the letter T Wow okay sure these animals have been known to lay fertilized eggs up to four years after mating thanks to special sperm storage compartments in their bodies what are they a tawny owls be tawny frogs see Texas map turtles or D tiger salamanders I was almost definitely feeling invertebrate but there I was wrong I'm gonna go to saunders cuz they do weird stuff it's not so definitely don't think i mean i know that some likes like sharks do weird stuff like this so my initial perspective was definitely not owls they're way too complicated to do something like this but now i'm going to say it's sea turtles you probably don't think all that often about how Turtles mate but it's actually pretty cool all female turtles have sperm storage tubules in their oviducts the tubes eggs pass through and they can keep viable sperm cells in those tubules for years which allows them to continue producing offspring even if they haven't made it in a while this is obviously helpful if there aren't many male turtles around but some researchers also think it allows females to influence who father's their babies even if they've made it with multiple partners so she decides one male is healthier or generally better than the other she could choose to pass his genes to her offspring question 6 is scientists observe weird weather all the time on other planets and moons but our research methods have even become good enough to detect some types of weather on exoplanets so far what weather have we found evidence for outside of our solar system a thunderstorms B tornadoes C tsunamis or D typhoons thunderstorms because they're the most chemically active of those things yes you're right the answer is a thunderstorms in 2009 astronomers discovered a planet about a hundred and twenty light-years away called hat P 11 B we find exoplanets all the time but what was especially strange was that in 2013 another researcher suggested there were radio signals coming from this planet as usual though they probably weren't from aliens because they never are instead some scientists think they're evidence of huge thunderstorms 120 17 conference papers suggested that if this planet had storms with at least a couple hundred lightning flashes per kilometer per second that would be enough electricity to generate the radio waves we've observed and since we have seen that kind of flash density during some volcanic eruptions it's not unheard of like a lot of things in space we just need more observations to confirm and now for the last question you're lying before I was lying before this is your first try doing this today but now I am so you can get ready to place your bets this is the betting round this is the betting round so for the last two questions we've swapped places Hank has a thousand points Sal you have 900 points to bet oh there's so much game theory in this now and before you do I'll tell you that this question is about another thing that starts with T the top cork oh it's about that top spark or anything I know about clocks is your something me too Barney yeah I know everything I know about quirks I know from writing that song or having Henry from minutephysics tell me how it's wrong it's got a commercial break and now we're back maybe from the break with our final question the existence of quarks tiny particles that make up things like protons and neutrons was proposed in the 1960s but it took until 1995 for scientists who officially discover all six of them the last quark found was the top quark it's the most short-lived of these particles but it's also the heaviest thing if that's the only thing I knew it so the final question is which of these has the most similar mass to atop a a hydrogen ion be a helium atom see a Gold atom or D a lead atom groaning noises I mean that's a big quark man okay okay ready ready yeah you can show your answers we said the same thing and you're both wrong the answer is a Gold atom yeah it's C gold a gold atom weighs about 197 atomic mass units which is just a teeny tiny fraction of a milligram but it's still one of the heavier atoms on the periodic table which makes it pretty amazing that one quark one of the building blocks of matter weighs about the same scientists are still trying to figure out exactly what the top quark does since it doesn't make up protons and neutrons like other lighter kinds of quarks but they think it could have something to do with giving other particles their mass which physicists have been trying to understand for a long time so I guess that leaves us with Hank with 201 points and Sally with one point Hank's the winner by 200 points hey you're welcome Amanda I'm sorry Kelvin if we took away that four you're going negative with one and you would have tied that the universe is balanced and thanks for playing and thank you for watching this episode of scishow quiz show if you'd like to see more
