Hank vs Aranda: The FINAL FACE-OFF | SciShow Quiz Show

[Music] greetings Internet and welcome to scishow quiz show I'm your host Michael Aranda if you are the most attractive scishow host I must say I don't you ever get mistaken for me near not wearing a black shirt all the time yeah me too you're welcome thank you in real life my name is Blake de pastino and I'm their editor in chief of scishow and also co-host of PBS eons with this guy who'll get to later but I'm only here today to officiate over the final face-off between these two scishow hosts on my right is the real Michael Aranda hmm can I ask you a personal question tell me about your here you've updated your look have I yes I just let the blonde grow out and I haven't gotten around to bleaching it yet I'll be back I'll be back I like it I actually getting my own blonde streak if you consider grade to be a very very light shade of blonde I left is eccentric billionaire Hank green hello I die all my hairs and you know he is right - enough to introduce you we're all wearing black today because this is the last episode for a long time of scishow quiz show before we may be updated in some ways but I'm wearing like confetti sprinkles maybe it's black it's got a little blue in it you're right it is deep navy school illusion I don't wanna care either it's like the dress is it black or navy I'll tell you what somebody's got a better bicep than somebody else so these two dummies are playing for prizes but they're not going to receive the prizes Curtis did they will go to patreon patrons who we've selected at random who are they you'll be playing for a Sandra Reedy hello Sandra and you what's your name will be playing for Daniel Bryan Daniel O'Brien and to show our players and audience what they will win here is a lovely and talented Stefan chin Stefan where am I oh it's the prize well my friends this is it this is our final time together for now but you know what that means everything's on sale everything must been all prizes are 40% off 60% off 90% off wait what's that oh there's nothing left wait looters what I don't know what's happening well Sandra and Daniel you're definitely still getting the autograph car from the final round of the show and the person who ends up with the most points will get the commemorative I won scishow quiz show pin it's made of metal but the biggest loser of the show will get the last final and the rarest of the rare pins because it's the last ever I lost scishow quiz show pin well I guess this is it coming at you from the prize zone this is Stefan chin signing on okay now I'm gonna start you each off with a thousand points each trying to get a correct answer you will gain points and if you give a wrong answer you will lose points yes do you follow that yes yeah okay so arbitrary is it so without further ado let's jump into our first round mm-hmm looks can be deceiving okay this is a picture round so all of our answers will be based on images you ready mm-hmm plants and animals come in a dizzying variety of colors in many cases these colors are based on pigments and those sign-ins for example art pigments that give plants fibrin chains of red purple and blue but as purple were interested in today because my question to you is which of the following four purple fruits or vegetables does not actually exist okay the tomato be the cauliflower see the strawberry or deed the line ooh a purple line oh I forgot we had to buzz in i'ma say D no I wasn't gonna say D but cuz you lost points I'm gonna say C that strawberry looks fake to me that is correct hey I don't understand the answers to these things but I have a colleague who does so here's smart Blake to explain the answer thank you dumb Blake anthocyanins aren't just pigments they're also antioxidants meaning they can help wrangle charge free radicals that can cause harm to cells now some people think that foods high in anthocyanins are especially good for you like that purple cauliflower but the science behind that claim isn't exactly solid nonetheless scientists have found ways to get more of these molecules into foods that normally don't have them which is where those blue tomatoes and purple limes come from garden variety Tomatoes don't usually have anthocyanins in their fruits themselves but some wild varieties do so with careful pollinating and selective breeding researchers have been able to produce tomato plants that make purple fruits and most limes don't produce entha sign-ins naturally so to get purple ones have given Mexican limes the genes from grapes and blood oranges which sounds rather delicious as for strawberries they do contain anthocyanins but not enough of the blue ones to make the berries look purple and so far as far as we know no one has tried to breed or engineer purple strawberries back to you dumb Blake I'm glad you won oh so there might not be a purple strawberries yet hmm but I am all about their development because they look delicious let me redirect the conversation in slightly and let's talk about cockroaches Oh there are over 7,500 species in the order black todya bola to do which i think is hilarious because how whoever named the cockroaches we're like you're looking at cockroaches and you're like oh yeah yeah we'll just say it means something in Greek anyway blat Odia is the order that includes cockroaches and they are incredibly diverse some are even downright beautiful so I had no idea I thought cockroaches were one species they would think under different cockroaches this is amazing news I mean probably not amazing it is for everybody I'm excited though I am too I mean it's why I was I can't get excited about cockroaches I yeah that's great which of the following is not one of those cockroach species oh okay we've got pictures oh yeah so is it a the red stripe anyone be this noble bug see this spotted beauty D this large winged bug huh E this glowing beast or F this little blue beauty okay boy oh boy they they are staggering variety hit me I'm gonna go with F I was gonna go with that oh you saved me I lost points oh thank you I will go with I don't know like a well there was so many there were so many the roaches that we love to loathe are just a small fraction of the order blue todya the ancestor of all cockroaches split from its insect relatives right after the end-permian extinction 252 million years ago and in this post extinction world there was room for roaches to diversify which is probably why you can find all sorts of pretty cockroaches today you can even find ones that mimic other insects including beetles and fireflies with that picture on our line was a true Firefly not a cockroach mimic now you astute viewers might have noticed that there's a termite in that group as well and that's because technically speaking termites are cockroaches a pair of studies has demonstrated that termites are an offshoot of the cockroach order basically a version of roaches that lives in colonies but the interesting thing is that this split took place around 150 million years ago a good 50 million years before ants are be started living in colonies so good for them I guess back to you Blake I once filled a cockroach on my face with a shoe no the cockroach was on the counter I was asleep at the time and I oh yeah and I woke up and I was like there's a cockroach on they leave like squish on your face yeah it was smelled really bad on the inside huh think about be ahead for now but it's anyone's game because it's time for round 2 which there's our patron potpourri oh is that why it smells so good in here suddenly if yeah we asked our patrons to vote on some topics for potential questions and these are the ones that they voted for and it's about blood do you ready oh I have some of that what blood type are you really you should know that oh I'm the best one I am a positive and it's only a plus I've ever gotten I'm very proud of it so a blood type is a combination of special molecules called antigens that you have on your red blood cells hmm like a person with a B+ has a and B antigens as well as rhesus D antigens which is the plus and so these three antigens and various combinations of them give us the eight major blood types that we know of mm-hm and your blood type is super important because it dictates who can receive your blood but your blood type is actually an oversimplification because there are many other rare blood types hmm these happen when people have or lack other antigens so the question is how many of these blood antigens are known to science oh is it a around 35 be a little over 200 see more than 600 D over 2,000 so it's a total number of known blood antigens known to science so there's like zoos like I can't look up at card huh I guess I look first and I'm gonna go over 2,000 that is incorrect well but I was talking about all animals not just human that's not what the questions so therefore judging on this we don't have judges because we're making us all yes B that is also incorrect is it it was more than six hundred two thousand is more than six hundred but we go by Price is Right rules I was in so I think I should get those points what if we just give Michael a thousand points for hosting special oh okay what do you mean even when a donors blood is matched with the recipient like a person with a negative blood is given o-negative blood transfusion reactions can still happen and that's because there aren't just three blood antigens there are hundreds over six hundred as of 2019 and new ones keep being discovered those discoveries generally occur when something goes wrong when a human body encounters a blood antigen has never seen it mounts an immune response to it so new antigens are generally discovered when an unexpected reaction occurs either during a transfusion or hopefully when blood is being tested before being used if something strange does happen like two blood samples clumping together that could indicate that either the donor has a new rare intogen or the recipient Lexx one that most other people have in other words one of them has a rare blood type from there scientists have to track down what actually caused the reaction can figure out what's different about the blood cells involved so while we think of human blood is coming in eight flavors if you were to take into account all of the known antigens in all their possible combinations there are actually millions of human blood types those eight are just by far the most common a while smart Blake was talking we decide the plate gets 10,000 points but why thank you but you can't win because you're hosting oh that's true and then not have to give it to the patreon patron and then they're all the tax ramifications of semi existent gameshow okay so moving on from human blood let's turn to another delicious liquid day whiskey Oh sometimes that's in human blood well probably not actually whiskey let the whole of the whole whiskey yeah whiskey is made from mashed fermented cereal grains like Captain Crunch or Froot Loops it says here yeah and the unicorn think that they sell at Costco did that also is included in this you can make whiskey from that it's not exactly clear who distilled the first whiskey many would say that Tennesseans perfected it hmm because Tennesseans added a step to the process known as the Lincoln County process so what happens during this process is it a aromatic compounds from sweet woods like sugar maple leach into the whisky be new aromatic compounds are made when the booze is heated in the barrel see new aromatic compounds form when the booze is vigorously stirred or a/d a significant portion of that yes just like that d a significant portion of the aromatic compounds are moved by charcoal hmm yes mr. green with D D yes Scotch is only Scotch if it's made in Scotland and champagne is only champagne if it comes from the old province of champagne in France but the key to making Tennessee whiskey even more than the place is the Lincoln County process that's the charcoal mellowing step that by law defines Tennessee whiskey because sugar maple is usually used for the charcoal you may think that Tennessee whiskey sweetness comes from the wood but this process doesn't add sweet flavors it actually removes some of the chemicals in the booze and chemists have only begun to investigate exactly what's taken out researchers at the University of Tennessee studied the chemicals in whisky that humans can smell called odorants and compared them before and after this critical step unsurprisingly the filtered whiskey had a milder smell but the researchers were shocked to find that some odorants decreased by up to 30% so that charcoal really does take a lot out of the booze in future studies researchers hope to bury things like how long the whiskey filters and the ratio of charcoal to whiskey to figure out what makes for the tastiest final product please enjoy this quiz show responsibly and now back to regular dumb Blake quite interesting indeed let's see what other patrons are interested in apparently it's monkeys oh yeah I'm gonna be my blood whiskey monkeys all the best thing this show has everything these are very smart animals that can learn new behaviors so it shouldn't be surprising that monkeys that hang around humans have all sorts of weird things but the closer researchers have looked at wild populations the more they find that monkeys do surprisingly human things even when they haven't been influenced by us which of the following behaviors has been observed in macaques that have lived around humans and in ones that aren't usually around people is it a bartering be flossing and it's helped you specify not dancing but flossing the teeth okay I would empty my pockets to see a monkey flossing yeah I would pay I give all the money I have to see that see weeding grasses d wearing coverings on their feet oh hey you saved me again thank you Michael ah I just had a bunch of fish tacos and I kind of need to foster myself right now but I can't be flossing right that's correct washing their teeth I said it can't be flossing and you just told me at one it is so you get that I'm giving you this point you're welcome Wow very lucky I too would enjoy seeing a monkey flossing but it turns out that behavior that's been observed in primates is the kind having to do with dental hygiene in monkeys tooth flossing was first reported among long-tailed macaques in Thailand in 2007 and at the time it was thought to be a novel behavior because in general it was thought that tool use wasn't very common in monkeys that was more of an ape thing but these macaques lived in and around a Buddhist shrine where there is abundant material for them to work with in the form of human hair and lo and behold as scientists observed more populations of monkeys they came to realize that flossing wasn't unique to the macaques at the shrine Japanese macaques have somehow picked up the habit - and has even been observed in macaque populations that don't live alongside people in the absence of human hair monkeys will faust with pretty much anything that's fibrous from coconut husks to blades of grass to even feathers but not all monkeys floss which suggested it's a learned behavior path from one monkey to another and that might also be why female monkeys exaggerate their flossing movements in the presence of their young which is just adorable back to you Blake I was just so excited that was the right answer whooping that actually had the fossa dancing was gonna be the answer oh yeah they also then I mean a macaque could definitely play for tonight no doubt you think so oh yeah that well would it beat you it would be me probably beat me - okay let's tell you the scores Hank green has 1400 whoo Michael Aranda has 1500 quite an - dude it has 10,000 yeah and with that it is time for our final round blue sharpies out gentlemen this is your chance because it all comes down to how much you bet and how you answer the question in this last round which our writer has titled waste not what not and as it happens this question is also chosen by our patrons and it's also about poop oh yeah specifically bat poop or as it's often called in a more sane t-turn guano okay but first let's pause for a break okay we're back anyone who has ever had bats take up residence in their attic know that that's poop a lot yeah and has it happened to you no I'm just saying like I almost pooped - lot and good for them right yeah you got to be regular if you're gonna be happy this makes them an important player in many ecosystems there are entire cave systems that rely on bat guano and over the centuries people have found it to be a very rich and useful substance - now which of the following is not a way that people have either used bat guano or are currently investigating using it okay there are only six choices ah so brace yourselves oh goodness gracious is much harder is it eh explosives be adhesives see protein powder D compost activator e detergent booster or F livestock feed supplement I mean all right you ready ready we both said C and you're both incorrect Oh which would you wager all the points oh wait I do high-five as excreted waste goes guano is incredibly useful that's why people have been mining it and using it for centuries it's high in nutrients like nitrogen and phosphorus which makes it an excellent fertilizer and all that nitrogen also makes it the perfect ingredient in explosives you see to make gunpowder you need potassium nitrate also known as saltpeter and bat guano contains a lot of nitrates which can be extracted and mixed with sulfur and charcoal to make gunpowder really there are so many uses for guano it's almost unbelievable scientists have isolated useful enzymes from the bacteria that live in it which you including potential detergent additives so yes bat poop may someday help clean your clothes and because some bats eat insects their guano is also an excellent source of chitin a polysaccharide that makes up insects exoskeletons chitin and similar molecules have a wide range of applications some of which are in medicine and food like protein powder though it's not at all certain that the chitin found in bat poop could be approved for human consumption it might be for livestock though researchers have considered using it to supplement livestock feeds lots of animals already equine of course that's one of the most important foods in cave ecosystems but as of yet no one seems to have suggested looking for it he into stuff maybe they will someday who knows back to you done Blake I almost went with that one I thought about it uses as well but I was like no one would eat protein powder with bat guano my thought was shouldn't the bats have used the protein but I guess if it's a livestock supplement then like I don't have my protein powder with that back 100 in it I'm livestock I didn't quite insist on it yeah I'm at the juice bar at the gym and like please more Becca no I don't I don't doubt it don't doubt you Daniel congratulations yes zero point zero points I thought for Daniel I was playing for Dan you were playing our Sandra you're playing I was playing through Sandra you were playing for Daniel yeah apparently not because everybody's a loser it says use both their birds victorious today which is not true but you will both reign as champion a scishow quiz show for sometime and that's because we've decided to revamp our quiz shows we want to spend some time retooling it thinking about it and we'd like input from you what you would like to see would you like different kinds of questions there kind of format a new set do you not want to ever see me on the show again there are a lot of options let us know in the comments in the meantime you can see these fellows still scishow every week I have to do is subscribe and you can see me on PBS Aeons at youtube.com slash yawns whoo [Music] you [Music]
