what’s up guys today we are back and
we’re fulfilling a request that came out
of the comments from Phil R who says
freeze the heart and liquid nitrogen
then smash it into pieces just like my
ex did Phil I’m sorry to hear about your
misfortune but a lot of people are
supporting your comment so that’s the
experiment we’re trying today now you’ll
probably recognize this heart from the
casting experiments we did where we
cloned it in chocolate and made a two
pound solid chocolate heart for
Valentine’s Day that was pretty awesome
but Valentine’s Day is over so I get a
big thermos of my homemade liquid
nitrogen a glass jar from our vacuum
chamber experiments and a wide variety
of tools so we can chip into this thing
and dissect it in a random style
now I’m no biology expert so I printed
off a little reference guide here that
we can use to figure out exactly what
we’re hacking into and maybe we’ll learn
something about how the heart works as
we do so looking at these pictures here
you can see this is kind of like a
mirror image of the heart so right here
we have the right atrium the right
ventricle and over here we have the left
ventricle and the left atrium then up
here we have our arteries and valves
apparently these little things here are
small muscles that are from when the
heart developed and they don’t really
seem to serve a purpose so let’s go
ahead and transfer liquid nitrogen into
the jar first hopefully our glass jar
doesn’t crack from thermal shock because
if it does we’re going to be wasting a
lot of nitrogen nitrogen is interesting
stuff like as this glass cools down to
temperature it actually does this rapid
boil at the end where we get little bit
spilling out everywhere which is too bad
because this stuff is really precious
and hard to make all right little heart
you have served us well it’s time to
meet your frosty faith here we go oh
yeah
I always forget about this there’s like
this nitrogen vapor there and whenever
something warm touches it it like
creates this little force field that is
super cool that is not a sin it’s like
ripples in the ocean except it’s
nitrogen vapors how cool is that it’s
not even touching the nitrogen yet here
we go and we have contact
[Music]
what’s really funny is you can still see
little bits of the red chocolate and
there’s even some blue silicone from we
poured the mold stuck down inside one of
these arteries that’s been about two
minutes there let’s just see how the
outside of the heart is looking oh yeah
that’s a little frosty this is hard in
the rock now a heart of this size I
imagine is going to take at least 10 to
20 minutes to freeze all the way through
because although the outside is freezing
solid there’s so much mass to this heart
that it’s going to take quite a bit of
time for the cold to penetrate all the
way through and I would like this to be
completely frozen by the time we start
chipping into it so let’s just go ahead
and plop it down in the nitrogen and let
it sit for 20 minutes oh well my tongs
got stuck okay I’m just going to dip
this in by hand and we’ll see how much
nitrogen that displaces you can already
see it’s starting to boil out the top
and that’s because this heart is so warm
the nitrogen is going crazy and I don’t
want to lose too much of it so I got to
do this kind of slowly here let the
heart settle in look at this there oh
here it goes that was an accident
started and there goes the nitrogen wow
that froze up quick look at this the
artery is already solid right there
that’s already solid about half my
nitrogen just spilled out so we’re going
to try this again a little bit slower
and as that boils down we’ll just keep
it topped up with nitrogen and give it
about 20 minutes to set so side note I
actually made this liquid nitrogen I’ve
got a generator that took a couple years
to set up but it’s finally working and
this is the first batch of homemade
liquid nitrogen that have actually put
to use and it looks like it’s doing a
good job
I mean it’s working homemade liquid
nitrogen guys video coming soon
all right so update guys it has been 20
minutes that our heart has been sitting
in a bath of liquid nitrogen let’s take
a peek inside and see if anything’s
changed
here we go
oh look at that guy’s it has cracked you
can see it’s cracked right through the
right ventricle and it’s split over into
the left ventricle on the left atrium
there’s a possibility that’s from when I
was dropping it I was a little bit too
abusive with this thing but I didn’t see
any cracks initially these have all
popped up in the last 10 minutes so the
question on my mind right now is after
20 minutes in liquid nitrogen is this
thing frozen completely solid or is
there still some gummy meaty tissue on
the inside there’s only one way to find
out so let’s grab a hammer and a chisel
and begin chipping away at it that is
frosty it’s got to make sure I don’t
drop it as I transfer it over because I
don’t want it to smash prematurely and
look at the way nitrogen is dripping out
the bottom it’s almost like these cracks
the nitrogen seeped inside the heart and
now the dripping back out here we go oh
look at the way the nitrogen Skittles
around the plate here that right there
my friends is the latent frost effect
the same thing happens with water and
extremely hot surfaces now let’s make
this into a little game of pong start
off here let’s just see if we can kind
of chip the side and see if we can pull
that top panel off because I think that
would be really interesting if we could
just take a peek right down inside
that’s actually pretty hard all right
let’s try shipping it out like this
oh wow look at that that whole piece
just comes right off it’s like a cutaway
and it is frozen completely solid what’s
amazing to me is how thick that muscle
is originally I was thinking it was
probably just a quarter inch thick but
that goes like a good inch and a half oh
my goodness look at the texture up here
that’s kind of an interesting texture
you can see the inside of this chamber
which I’m guessing is the atrium has
almost like these little wormy wall type
effect right diving a little bit further
here let’s pull away this wall of the
right ventricle Wow
you can see the membrane here where it
separates the ventricle from the atrium
there’s even like chunks of ice in there
look that is one icy heart so here we
got the bottom tip of the heart which
literally just fell off I mean it came
off in chunks and pieces and look at how
thick those muscle walls are that’s like
a good inch and a half to two inches
absolutely crazy I was not expecting the
walls of a heart to be that thick and
from this view here it’s kind of
interesting because we’re looking up you
can see there’s not a lot of space there
but those are the cracks where the blood
is flowing so we’ve got so much muscle
in so little space and that’s probably
why these things work so effectively now
admittedly I have never actually cut
open or dissected a heart before and
biology wasn’t my strong subject so what
I’m going to do is find a good video
that explains exactly how the heart
works and put a link in the description
so if you want to know more about the
purpose of the heart and its functions
you can learn for yourself oh that is
interesting you can see on this one
there’s a cross-section of something
that looks like a vein running out of it
I imagine this thing right here is
probably one of the valves that opens
and closes as the blood is pumping and
that may be what we have going on over
here you can see little cross-sections
of veins and whatnot this thing here
looks like the aorta and you can see
there’s still a little bit of silicone
in there from where I cut it away after
it came out of the mold
that’s very cool guys and slightly
educational you can see the silicone
that we poured seep down quite a ways
into this heart here I can’t get into it
as much as I’d like to because there’s a
huge chunk of frozen muscle there so I
think the only thing left to do now is
smash this and break this heart in
pieces kind of like your ex did to you
Phil all right
glasses hum for safety you don’t want
chunks of frozen heart flying at my face
here we go three two one bang pieces
everywhere you guys gonna smell really
bad a little bit later today let’s take
a look at the damage what do we
yeah look at that so there’s a healthy
amount of silicone that got in there
that’s really amazing there’s one other
little piece I want to try and that’s
this one it looks like some kind of
alien deformity let’s just go ahead and
smash that real quick Oh everywhere it
explodes explodes like an ice cube being
hit with a hammer it was basically what
it is
and now we’ve got chunks everywhere
little ear piece like Vulcan ears live
long and prosper
so there you have a guys we successfully
dissected a heart using our friend
liquid nitrogen it was really impressive
to me is how thick these heart muscles
actually are I always assumed that the
hearts were full of mostly blood but it
doesn’t seem to be the case it seems
they’re mostly muscle with a little bit
of blood being pumped in very quickly
that is really cool experiment that was
a lot of fun and thanks again to Phil
are for suggesting this experiment and
to all of you who are supporting them
check your inbox Phil I’m sending a
twenty five bucks and to the rest of you
watching hopefully you had fun hopefully
you learn something new and I look for
you in the next video
talk to you then that didn’t break haha
