hey guys we are back in the lab with a
10 pound block of dry ice to answer the
question what does dry ice do in a
vacuum chamber the request for this
experiment came in the comments from
Jason gamer thanks for your request
Jason I’m sending $25 your way now dry
ice is solid carbon dioxide with a
temperature of about minus 109 degrees
Fahrenheit but that’s at sea level if we
put it in a vacuum chamber and suck the
air out the pressure changes and the
properties of the dryest change as well
now people ask all the time where do you
even get dry ice I just went down to the
grocery store and picked this up for
about $13 they usually have a container
near the front of the store where they
keep it and you can get some as long as
you’re over 18 ok cool let’s jump right
in clothes make it hard to work with
being safe is so restrictive ooh good
stuff hey just a thought will your
tongue stick to dry ice if you lick it
mmm apparently not but it is a little
fizzy my tongues local okay so one
problem guys this isn’t gonna fit in
they’re gonna smash it up a little bit
so let’s grab a hammer a little work oh
you think I can karate chop this in half
[Music]
[Applause]
that’s a lot harder than I thought and
it actually did hurt quite a bit but we
did it we did it that is how you break
dry ice there we go all right cool
so we’ve got a few chunks of dry ice in
there this is that our driest is having
a private moment look at the way the
vapor is falling in filling up the
container right now what it’s doing is
pushing the oxygen out and filling the
container with carbon dioxide so we’ve
got a few good chunks and rice in our
vacuum chamber let’s go ahead and put on
the lid close the valve get this thing
fired up let’s see what happens
all right so it actually is pulling
vacuum pressure it’s probably not the
smartest idea to be using a glass
container because the dryest can
actually cool down the glass at the
bottom while the glass at the top stays
warm so that creates a difference in
temperature that could expose a glass to
shattering and imploding so it’s a
little bit dangerous from here I can see
the gauges probably around 23 inches of
mercury which is about as low as that
vacuum pump can pull I’m going to close
this valve and turn off the vacuum pump
watch the gauge as I do now it’s about
22 inches of mercury but as the dry ice
continues to vaporize that carbon
dioxide you can see the container
actually starts repressurizing and the
gauge is dropping in pressure so just to
go a little bit further let’s release
the pressure let’s add a little bit of
warm water to get this thing vaping a
little bit and then turn the vacuum
chamber back on let’s open the valve in
three two one
[Music]
sweet dry ice vapor it actually smells
like vinegar and I think that’s because
the proto buddy haha I just poured some
hot water it’s about the hottest I could
get it out of my tap and pouring this in
will actually help insulate the bottom
of the glass as well and reduce the
chances of it imploding on us oh that’s
cool
oh man who doesn’t love dry ice
[Music]
surprisingly I can actually breathe that
quite well I mean I thought it’d be
stinging my lungs like if you put dry
ice into a balloon and then breathe it
it hurts lungs quite a bit but I can
breathe this just fine let’s go ahead
and add the rest of it
[Music]
so we now have hot water dry ice in our
vacuum chamber so let’s go ahead and put
the lid on and see what happens when we
turn on this time this valve open this
valve closed you can see if I actually
try and hold this container close the
lid will actually start popping up
there’s nothing I can do about it
and if I open the exhaust valve we could
actually get dry as vapor shooting out
of that looks cool let’s right out of
the movies like a busted pipe line or
something sweet okay let’s close that
off and turn on the vacuum three two one
[Music]
oh and we actually are pulling back in
pressure that’s surprising to me because
with how much vapors coming off I
wondered if that would kind of
neutralize if it equalized but we’re at
about 13 inches of mercury right now and
steadily increasing so there used to be
a really dense thick white fog and that
has been reduced to the point now where
I can actually see the dry ice blocks
inside there still is a white vapor but
that is slowly being pulled out if you
look closely you can even see a little
bit of that vapor flowing down the tube
here to the vacuum pump now I’m not
exactly sure how good it is to be
running carbon dioxide and water vapor
into a vacuum pump but hey it’s for you
guys it’s for science
all right so update guys we’re down to
about 20 inches of mercury right now so
let’s just flip the valve open let all
the air back in and see what happens
oh and now you can hear it bubbling
again that’s interesting so we tried a
massive amount of dry ice in a container
what would happen if we just tried a
very small amount of dry ice let’s break
off a small chunk throw it into our
pressure cooker and just see what
happens there throw that in set the
vacuum on gauge is rising rising fast
now that looks good oh yeah that’s a lot
faster and we had all that dry ice in
there we’re almost up as far as this
thing can go right now 22 inches of
mercury oh wow look the Dreyse is
shaking a little bit
it’s like vibrating looks really nervous
right now if I grab this lid and shake
it there’s no way that’s coming off but
interestingly enough like the dry ice
isn’t doing much in there it’s still
sublimating like it normally would but I
don’t know if it’s sublimating any
faster but I really have no way to gauge
that so yeah dry ice in a vacuum is very
anti climatic nothing’s really happening
so there you have a guys a very fun and
a very cool experiment with dry ice and
a vacuum chamber and thanks again to
Jason gamer for requesting this
experiment if any of you have
experiments you want to see we try and
post your suggestions down below thanks
for joining me for this video I’ll be
looking for you in the next one talk to
you then
[Music]
excuse you
