hey guys we are back in the lab with a 10 pound block of dry ice to answer the
10 pound block of dry ice to answer the
10 pound block of dry ice to answer the question what does dry ice do in a

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