workshop today we are trying something
out that hundreds of you have asked for
down in the comments we’re going to see
what happens when we put soda in a
vacuum chamber we’re gonna try a bunch
of different ways we’re gonna put whole
cans in the vacuum chamber still closed
we’re gonna try warming up some cans and
then putting them in the vacuum chamber
we’re gonna try putting open cans in and
then we’re gonna try pouring soda into a
different cup and putting that in and
learn all about what happens with soda
in a vacuum let’s get started first off
we’re gonna go with what I think might
be the least exciting version of this
experiment we’re just gonna open a can
of soda put the whole thing down into
the vacuum chamber and then pull out all
the air we go got our can right in the
center of our vacuum chamber pop the top
on take out all the air here we go
turning on the vacuum and pulling out
the air three two one so far nothing
it’s not even bubbling in the can yet oh
now it’s bubbling in the can a lot and
out of the can and off onto the bottom
of the chamber just pouring out I wonder
how much of the soda will actually
manage to pull out of the can and put on
the bottom of the vacuum chamber we’ve
lost about a quarter of it out of the
cans so far now it’s just bubbling a lot
it kind of looks like it’s boiling
inside the cam so something is still
happening our pressure got to about 25
inches of mercury and then leveled off
for a minute and now it is very slowly
starting to pass that as it pulls all
the excess gas out of our liquid now at
some point and we may already be at that
point it is just going to start boiling
the water in the soda of course it won’t
be heating it up it’s just that with the
lower pressure the boiling temperature
of the water drops way down well the
bubbling is slowing down it is still
bubbling clearly but there’s less of it
let’s see what happens we turn off the
vacuum just bubbling for just a minute
it is still almost a perfect vacuum
inside this chamber this point all right
reintroducing some pressure three two
one
[Music]
smells like soda this vaporised
soda alright let’s see how much of this
can is lost so we are down to about
right here so I think we lost almost a
third of the contents of this can of
soda as it bubbled out at the top it’s
got soda floating around at the bottom
of our chamber now I think the real test
might be to see if there is any
carbonation left in this or if it’s just
it’s about as flat as if you’d left it
open for a couple of days on the counter
there’s no fizz in it just pulled it
right out there you go if you really
like flat soda here’s a way to make that
happen very quickly I don’t recommend it
it’s worse alright that was pretty cool
now the next one I was gonna try was
pouring some of our soda into a glass
and putting that in the container but
you know what I think it’ll be more fun
if I just pour it straight into our
vacuum chamber with no glass in the
middle get in the way so I’m gonna pour
in like four cans of it and we’ll see
changed my mind I’m doing more than four
I just hope it doesn’t bubble so much
that it gets all the way to the top I
don’t think it will
well we’ve got some bubbling actions
starting that’s for sure now we’ve got
lots of bubbling action starting it
looks like a pot of boiling soda
goddamnit I thought it would get a
little bit more violent than that I
thought we’d have bigger bubble action
with the bubbles climbing higher and
sort of sticking together almost a foam
pressure is still dropping a little bit
you can see we’re getting slightly
larger bubbles at this point there’s no
longer any pressure outside of the
bubbles to poke them and pop them we now
have
considerably less surface bubbles
they’re definitely dissipating I think
that means we’ve pulled most of the gas
out of our soda
it’s funny how once you get down to
almost a complete vacuum the bubbles
really occasionally start to get way
bigger you never have huge bubbles while
there’s still pressure in there but once
there’s no pressure
sometimes the bubbles get giant does
look like some sort of mad scientist
potion almost a glowing orange just
bubbling even though there’s no heat
source to it there we go I think we have
fully deep pressurized these five cans
worth of soda so let’s add the pressure
back in and see what it’s like I’m
guessing it’s completely flat
yeah yeah that’s completely flat so I
guess it’s more like Mountain Dew drink
not soda just drink that’s your thing I
guess that’s fine not really mine let’s
move on to the next experiment so now we
know what happens if we just put a whole
bunch of soda into the container once
and suck all the air out so now let’s
see what happens if we put a sealed can
down into our chamber and pull all the
air out will the pressure inside the can
be enough to make it explode let’s try
it very close to a complete vacuum at
this point not a whole lot going on that
I’m seeing we’re not getting anywhere
like this so let’s try something else
first thing I want to try is this same
can at the same temperature but I’m
gonna shake it up a lot alright so in
theory that should now have higher
internal pressure to compete with a
comin up on 26 and still nothing all
right not getting anywhere at this can
let’s try the next idea the YouTube
channel action lab did a very similar
experiment recently and they had best
results when they heated up their soda
in a bath of warm water so we’re gonna
try that there we have it a nice big
bowl full of hot water I should get our
soda nice and toasty that’s what
everyone’s hot soda
oh they budged I don’t know what that
means but it budged
[Music]
hmm well even with the warm soda we are
not getting much of a result I’ve now
tried just about everything I can think
of to get this can to explode in the
vacuum chamber short of boiling it since
that’s not really what we’re going for
we’re gonna try something else we’re
gonna switch to a different soda and see
if this flavor it has more carbonation
in it and therefore more internal
pressure than the Mountain Dew does
we’re gonna combine all of our tricks
together and see if we can get a good
result we’re gonna heat one of these
cans up in warm water we’ll shake it up
a little bit and then we’ll put it in
our smaller vacuum chamber and see if we
can finally get one of these cans to
explode oh the bottom just distended so
pretty sure this thing’s gonna explode
nicely wow it was it like maybe 10
inches of mercury nowhere near a
pullback like it escaped it got out of
the container that’s how quickly that
exploded all right so maybe shaking it
wasn’t terribly necessary I’ve gots warm
soda all over the place let’s try it
again with one that I don’t shake that
much see if just being warm is enough
with this stuff it needs a little
all right just being warm didn’t do it
let’s try shaking it a little bit not as
much as before I thought I didn’t shake
it as much as before but apparently I
should get too much pee that’s kind of
interesting look at how there’s broke
just this one tiny little pinprick now
all the pressures going against it’s
just full
warm flat soda at this point but that
tiny little spot is what broke open
initially hurt my hand how hard it hit
I’m gonna get another can I’m gonna
shake it only like seriously just kind
of like a back and forth see what that
does just the tiniest little bit I don’t
see how this mess
the bottom got expanded still waiting
for that top to blow boom there it is
[Applause]
it’s Ted the cab backup kid fell over
when the bottom popped down and then
when it exploded it popped back up
that’s hilarious
it landed upright all right let’s let
some pressure back in it’s got
lemon-lime soda sprayed all over
everything this isn’t sticky it’s
interesting to me how this breaks so the
bottom expands a lot when the pressure
starts building up too much and then
what actually comes off the top gets
popped off of these cans it just sort of
tears through the sides of the metal
there you have it soda in a vacuum
chamber in a number of different ways we
use the mountain dew with the cans
cracked open and watched it erupted out
of there is the pressure drop down we
poured a whole bunch of our orange soda
down into the vacuum chamber and just
watch that bubble a whole lot as we
reduce the pressure and then we tried to
get our soda cans to explode while they
were sealed and we couldn’t get it to
work with the mountain dew but I guess
the lemon-lime soda has more carbonation
in it because when we heated that up and
shook it gently we were able to get that
to explode in the vacuum chamber I don’t
even know if the shaking was completely
necessary I think it just sped things up
a little bit and then on this can I
shook it and it just burst open without
any vacuum pressure at all this tiny
tiny little hole put out enough pressure
that I actually hurt my hand where the
jet of soda hit it this has been a lot
of fun thanks for joining us for this
video and remember to come gear yourself
up with hats shirts and other cool merch
at the king of random calm see you there
Ken can’t even handle it right now I’m not funny
