Welcome to Scishow Quiz Show
Scishow's favourite Quizshow
Today on the show
We have, the guy who signs my pay cheques
Hank Green
That's a really this shirt, you look really nice today
we do direct deposit anway
have you lost weight?
(laughter)
Going up against Hank
we have resident insect expert
Olivia Gordon
who is out newest host on Scishow
Hello Olivia
Hello Hank
That makes todays show, Host vs Host
Did we put a bunch of insect questions in there?
Because I'm not gonna do well
hmmm we'll have to see
I hope not, because then if I don't do well
that does that always makes me nervous
when it's like a bio chemistry question
and I'm like
contestants are competing on behalf of
patreon patrons tank today you are
playing for Chris Peters Chris Olivia
today you are playing for Thomas
Flanagan Thomas think we're gonna make a
good team
ok as usual I'm starting both of you off
with 1,000 points each time you answer a
question you will win or lose some
number of points depending on how good
your answer was whoever has the most
points at the end of the game wins some
special sideshow prizes for their
patreon patron Stefan
show our contestants and our audience
what they're playing for today thanks
Michael both Chris and Thomas will be
taking home autograph cards from the
final round with our contestants final
guesses and wagers on them the lucky
winner will get a lovely i won scishow
quiz show pin and the lucky loser will
win the highly coveted I lost scishow
quiz show pin and the winner will also
take home some secret scishow swag from
dftba.com back to you Michael
okay you guys ready right let's do that
thing where we answer questions in round
one is all about carnivorous plants
ok that's an insect most plants get all
the important nutrients they need like
nitrogen from the soil but carnivorous
plants usually live in nutrient poor
places and survived by capturing and
digesting other living things the
pitcher plant for example is basically a
slippery cup of sweet-smelling nectar
that's full of digestive enzymes and
bacteria just like never mind what
ok because i have excellent darlin first
called them insect in various plants
because he only saw them trap
invertebrates but since then pitcher
plants have been seen digesting small
amphibians mammals and other organic
matter that you might not expect to find
in there so what else do some pitcher
plants eat fruit fallen leaves animal
poop chunks of tree bark animal poop
that is correct it doesn't seem like it
would be a good place to get my
attention from pitcher plants have the
digestive power to break down vertebrate
and invertebrate tissues but a couple
Southeast Asian species attract mammals
for their nitrogen-rich poop instead of
tricking the animals into falling into
the digestive fluid soup it's more of a
mutualistic relationship three plant
species produce sugary nectar on their
inner lids and rims which tree shrews
love to eat shrews score down to dine
and use the plant as their personal
toilet some other pitcher plants
meanwhile actors comfy roosts for will
be bats the bats can climb in and out
without touching the pool of digestive
fluid so they get a safe place to sleep
during the day and the pitcher plants
get their nutritious guano that is a
hundred points for Olivia
well the good news is i have a thousand
and I didn't even do anything to get
them like basic income scishow quiz show
edition now I think it's important that
we take a moment to pay tribute to one
of the unsung carnivorous plants the
bladderwort mmm
despite having a kind of unfortunate
matter well i had that is back in
college it's pretty noteworthy plant
it's probably the most widespread
carnivorous plant and it has one of the
coolest trapping mechanisms which it
uses like a boss
the bladderwort lives in water or
waterlogged soil and has a bunch of
little underwater chambers that actually
suck in its prey like larvae or small
crustaceans and attracts them with a
cute little lid that snaps down so with
all of this in mind what is the bladder
board better at than any other
carnivorous plant it has the fastest
reaction time it can hold in store more
prey than any other carnivorous plant it
captures the biggest pray relative to
its size or it gets all of its nutrition
from its prey and none from
photosynthesis
Oh
didn't-didn't like I was their first we
establish this a it has the fastest
reaction time of any kind of this plant
it sure does Hank green you get 100
points all right tie ballgame
scientists have studied the traps or
bladders of a couple bladderwort species
with high-speed cameras and they all
have similar trapping mechanisms
basically internal structures pump water
out of the little bladders so there's a
lower pressure inside and a trapdoor
keeps a watertight seal so it's ready
for action when something like a tiny
crustacean bumps up against trigger
hairs on the door it opens in about half
a millisecond the walls expand sucks in
water and the prey and closes in about
2.5 millisecond the next fastest by
comparison are Pimpernel sundews when
something stimulates the tip of its
tentacle its tentacle snatches the
praying about 75 milliseconds
okay we're moving on to round 2
and since Olivia knows all about insects
this section is all about bugs bugs are
kinds of insects
wait what's there in about an insect is
that a question
just tell me bugs are terrestrial
arthropods okay what what are some non
terrestrial arthropods lobsters
Oh lobster is an insect it's not an
insect it's over fee
I got it icic so bug is broader than
insect yes okay got it
so the kind of bug that we're talking
about technology really ought in
computer programming the term bug means
some sort of mistake that makes the
program not work the way it was supposed
to the word was first used to describe
technical failures in late eighteen
hundreds like Thomas Edison referred to
errors and telegraph signals an
electrical circuits as bugs but there's
this almost folkloric tale about how
engineers started using bug and debug in
the language of computer programs in
1947 the mark to computer at Harvard
University which was designed before
math calculations wasn't working
what was the problem it was making a
buzzing noise like a be there was a
month stuck inside that one can i do
that connect can we do have to read for
all the meat cutter the rules here
there are no rules no yard is green
you are correct i was not stuck that's
200 points for Hank green
oh I get 200 hits around to the photo of
that in the Smithsonian in the American
Museum of American History is it is it a
dead moth that i am there to get like
zapped probably i would imagine i wasn't
exactly how it transpired over there
like like physical part closing together
in this giant machine
I don't know how it sounds like one of
those video games were like you have to
squash them off
it's good take that the story goes the
mark to computer was being tested by a
team of engineers including pioneering
computer scientist Grace Hopper mark 2
is designed to run using electromagnetic
relays small switches that control and
are controlled by electric currents and
when the computer wasn't working
engineers open it up to find a moth
trapped inside one of the relays they
extracted it and tape the insect into
the log book with the note first actual
case of bug being found
ok we're going to move on from software
bugs to surveillance bugs also known as
a covert listening device or those
things in the spy movies with the bad
guys what she's wearing a wire
I'm wearing why we're all wearing why
are all wearing wires right now most
simple bugs includes some sort of
microphone which received sound waves
and converts them into an electrical
signal and then a transmitter which
sends out radio waves
perhaps the most famous or infamous bug
of all time was a device known for
decades only as the thing in 1945 Soviet
schoolchildren in Moscow presented a
gift to the US ambassador averill
Harriman the gift was a thick wooden
plaque emblazoned with the Great Seal of
the United States but behind that seal
was the thing a tiny Mike connected to a
transmitter the most ingenious thing
about the thing was that it worked
without any wires or batteries the back
of the seal was Hollow and the mic was
on the front so the whole device acted
like a drum amplifying the vibrations
from sound waves that hit Soviet spies
in a van outside the embassy could aim a
high-frequency signal at the bug and
only then
would it transmit a signal that's cool
and ask this this is all new information
as it happens this device was designed
by one of the Soviet Union's most famous
engineers who is the mastermind behind
the thing was it
Igor Sikorsky inventor of the helicopter
Pavel Trankov discover of trend called
radiation Mikhail Kalashnikov developer
of the ak-47 assault rifle or leon
theremin inventor of the theremin I
didn't know that guy was Russian
mmm is that was again are you talking to
that guy i turned off and then I'd have
to answer because I touched it
ah the drink off I'm gonna go to drink
off because his works on radiation you
just lost yourself too
oh man see the thing about that though
is it was a guess but I felt like it was
the best guess so I should just I don't
need . but give me some credit
you have my sympathy does that mean I
have to answer
yeah d you are correct
oh that's cool I guess he also worked
with some stuff is an electromagnetic
fields did you do those things and also
we did an episode on him so he probably
some writer figured that out and
couldn't work it in the theremin episode
was like I'll put it in question why
should I known it
marilyn is most famous for inventing the
electronic musical instrument that bears
his name and whose spooky sounds
appeared in cheesy sci-fi movies in the
mid-twentieth century after he made that
Thurman used his expertise in both
electronics and acoustics to design the
thing which hung undetected in the u.s.
ambassador's office until $MONTH 1952
finally we have reached our double or
nothing around wherein you can wager any
number of your points on your answer to
the next question
and since we've been talking about sound
this next question is about the loudest
sound oh well you guys make your wagers
will be right back after these
commercial messages
welcome back we know
sounds created by vibrating objects
which makes waves that travel through
something like air to our ears which
allows us to here and we describe the
intensity of sound in terms of decibels
something like the conversation we're
having right now would be around 60
decibels but if you're listening to
something a hundred and 20 decibels that
would actually be sort of painful to
listen to start going to give you a
hundred twenty-two supposing you're
right now
no I don't want to let that happen
because of the physics of sound waves
there is a limit to how loud a sound can
be and still be considered normal sound
there is a point at which sound waves
become shock waves which can cause
sudden changes in pressure and
temperature so there's a certain decibel
level that is literally as loud as sound
can get and still be a sustained sound
so on earth at sea level
what is the loudest sound can be is it
140 decibels this just gonna be 188
vegetables 194 decibels or two hundred
decibels
oh oh well I've got ok i feel like i got
fifty percent chance
ok i should i should i should have been
zero but you could tell by lessening
could you tell what I just wrote no okay
I could you know I could tell you guys
ready
yes right show off your answers
oh well what
well what was wrong Hank green you just
lost yourself 1100 . hey it's all the
same to me
Olivia you just won yourself another 400
points the loudness of a sound is
determined by the amplitude of its sound
waves and generally there are areas of
high pressure where the sound waves are
and areas of low pressure in between one
sound generates waves of a hundred
ninety four decimals or higher
there's no air between the sound waves
and vibrations essentially create a
vacuum and vacuum that can be no sound
so it's totally possible that sounds can
be generated with the amplitudes higher
than a hundred ninety four decimals but
when that happens they create shock
waves that are asymmetric and distorted
rather than sustained sound waves as for
the other answers 140 decibels is the
sound of a jet engine
around 50 meters away the other two
recorded sounds in water a blue whales
call has been measured up to around 188
decibels and the pistol shrimp can snap
its claws shut really fast to create and
pop a bunch of bubbles producing
shockwaves over two hundred decibels
that can stun small prey
I do believe that makes Olivia and
Thomas Flanagan's our winners of this
