hey guys welcome back to the lab in this video we’re taking liquid nitrogen and
video we’re taking liquid nitrogen and
video we’re taking liquid nitrogen and putting it in a vacuum chamber to see if
putting it in a vacuum chamber to see if
putting it in a vacuum chamber to see if it will change from a liquid to a solid
it will change from a liquid to a solid
it will change from a liquid to a solid I’ve seen videos online of other
I’ve seen videos online of other
I’ve seen videos online of other companies trying this experiment
companies trying this experiment
companies trying this experiment actually solidifying nitrogen in their
actually solidifying nitrogen in their
actually solidifying nitrogen in their lab so can we replicate that experiment
lab so can we replicate that experiment
lab so can we replicate that experiment here in our lab today let’s give it a
here in our lab today let’s give it a
here in our lab today let’s give it a try I flipped the gauge around on my
try I flipped the gauge around on my
try I flipped the gauge around on my vacuum chamber so that when we place it
vacuum chamber so that when we place it
vacuum chamber so that when we place it upside down we can still get a visual
upside down we can still get a visual
upside down we can still get a visual readout now we can take our little dish
readout now we can take our little dish
readout now we can take our little dish fill it up with liquid nitrogen right in
fill it up with liquid nitrogen right in
fill it up with liquid nitrogen right in the center go ahead and attach our
the center go ahead and attach our
the center go ahead and attach our vacuum chamber and turn the pump on look
vacuum chamber and turn the pump on look
vacuum chamber and turn the pump on look at the way that vibrates check this out
at the way that vibrates check this out
at the way that vibrates check this out it’s actually vibrating right now
it’s actually vibrating right now
it’s actually vibrating right now because there’s a positive pressure as
because there’s a positive pressure as
because there’s a positive pressure as the nitrogen is expanding it’s trying to
the nitrogen is expanding it’s trying to
the nitrogen is expanding it’s trying to lift us off it’s almost like an air
lift us off it’s almost like an air
lift us off it’s almost like an air hockey table everything set let’s expose
hockey table everything set let’s expose
hockey table everything set let’s expose the vacuum port and turn on the pump
the vacuum port and turn on the pump
the vacuum port and turn on the pump [Music]
[Music]
[Music] okay it is pulling vacuum we’re at three
okay it is pulling vacuum we’re at three
okay it is pulling vacuum we’re at three inches of mercury liquid nitrogen is
inches of mercury liquid nitrogen is
inches of mercury liquid nitrogen is still boiling now theoretically what
still boiling now theoretically what
still boiling now theoretically what should be happening here is as we remove
should be happening here is as we remove
should be happening here is as we remove the atmosphere from the jar the boiling
the atmosphere from the jar the boiling
the atmosphere from the jar the boiling point of the nitrogen should drop so it
point of the nitrogen should drop so it
point of the nitrogen should drop so it may get to a point where it actually
may get to a point where it actually
may get to a point where it actually starts crystallizing and freezing right
starts crystallizing and freezing right
starts crystallizing and freezing right now we are at 11 inches of mercury and
now we are at 11 inches of mercury and
now we are at 11 inches of mercury and the vacuum is fighting that nitrogen
the vacuum is fighting that nitrogen
the vacuum is fighting that nitrogen because the nitrogen is expanding and
because the nitrogen is expanding and
because the nitrogen is expanding and the vacuum is working really hard to
the vacuum is working really hard to
the vacuum is working really hard to counteract that
counteract that
counteract that so about 14 inches of mercury now I’m
so about 14 inches of mercury now I’m
so about 14 inches of mercury now I’m noticing the bubbling of the nitrogen is
noticing the bubbling of the nitrogen is
noticing the bubbling of the nitrogen is actually reducing which means it’s
actually reducing which means it’s
actually reducing which means it’s cooling down to the point where the
cooling down to the point where the
cooling down to the point where the liquid may start to think about
liquid may start to think about
liquid may start to think about crystallizing oh you know what we should
crystallizing oh you know what we should
crystallizing oh you know what we should do is put a little bit of styrofoam
do is put a little bit of styrofoam
do is put a little bit of styrofoam underneath to help insulate it because
underneath to help insulate it because
underneath to help insulate it because right now I bet the plastic it’s sitting
right now I bet the plastic it’s sitting
right now I bet the plastic it’s sitting on it’s quite warm okay cool so I’m
on it’s quite warm okay cool so I’m
on it’s quite warm okay cool so I’m actually going to stop this right now
actually going to stop this right now
actually going to stop this right now let’s let the pressure back in and I’m
let’s let the pressure back in and I’m
let’s let the pressure back in and I’m gonna stick a roll of duct tape
gonna stick a roll of duct tape
gonna stick a roll of duct tape underneath it wow that’s cool
underneath it wow that’s cool
underneath it wow that’s cool I got a roll of duct tape with a little
I got a roll of duct tape with a little
I got a roll of duct tape with a little glass lid we’ll just stick that
glass lid we’ll just stick that
glass lid we’ll just stick that underneath there and that should
underneath there and that should
underneath there and that should insulate the bottom now enough where it
insulate the bottom now enough where it
insulate the bottom now enough where it doesn’t draw heat from the Plexiglas
doesn’t draw heat from the Plexiglas
doesn’t draw heat from the Plexiglas well add a little more nitrogen just to
well add a little more nitrogen just to
well add a little more nitrogen just to keep things happy cool and now you can
keep things happy cool and now you can
keep things happy cool and now you can see the nitrogen vapor that should
see the nitrogen vapor that should
see the nitrogen vapor that should slowly disappear and become very clear
slowly disappear and become very clear
slowly disappear and become very clear Wow the nitrogen has these little bursts
Wow the nitrogen has these little bursts
Wow the nitrogen has these little bursts that pop up very erratically yep just
that pop up very erratically yep just
that pop up very erratically yep just like that that’s amazing I don’t know
like that that’s amazing I don’t know
like that that’s amazing I don’t know what’s going on there but it’s like a
what’s going on there but it’s like a
what’s going on there but it’s like a little explosion from the bottom every
little explosion from the bottom every
little explosion from the bottom every now and then wow that was a good one
now and then wow that was a good one
now and then wow that was a good one this thing’s working hard man you know
this thing’s working hard man you know
this thing’s working hard man you know what we’re down to about 18 inches of
what we’re down to about 18 inches of
what we’re down to about 18 inches of mercury right now but it’s getting hard
mercury right now but it’s getting hard
mercury right now but it’s getting hard to see through this glass jar so I think
to see through this glass jar so I think
to see through this glass jar so I think what we’re going to do is stop the
what we’re going to do is stop the
what we’re going to do is stop the experiment here transfer this into the
experiment here transfer this into the
experiment here transfer this into the pressure cooker and then with the
pressure cooker and then with the
pressure cooker and then with the acrylic lid we should get a lot better
acrylic lid we should get a lot better
acrylic lid we should get a lot better view still looks pretty chunky I wonder
view still looks pretty chunky I wonder
view still looks pretty chunky I wonder if it’s just frost to go down in there
if it’s just frost to go down in there
if it’s just frost to go down in there from the Atmos
from the Atmos
from the Atmos alright guys so update I’ve cleaned
alright guys so update I’ve cleaned
alright guys so update I’ve cleaned everything out of the jar so there are
everything out of the jar so there are
everything out of the jar so there are no little chunks or crystals in there
no little chunks or crystals in there
no little chunks or crystals in there we’re going to pour in fresh liquid
we’re going to pour in fresh liquid
we’re going to pour in fresh liquid nitrogen and then we’re going to use the
nitrogen and then we’re going to use the
nitrogen and then we’re going to use the pressure chamber this time so we can get
pressure chamber this time so we can get
pressure chamber this time so we can get a good clear look through the acrylic
a good clear look through the acrylic
a good clear look through the acrylic and see exactly what’s going on alright
and see exactly what’s going on alright
and see exactly what’s going on alright everything’s set let’s get it pumping
everything’s set let’s get it pumping
everything’s set let’s get it pumping now we seem to have hung up right around
now we seem to have hung up right around
now we seem to have hung up right around 19 inches of mercury here 19 and a half
19 inches of mercury here 19 and a half
19 inches of mercury here 19 and a half come on you can do it
come on you can do it
come on you can do it you’re so close oh shoot my little
you’re so close oh shoot my little
you’re so close oh shoot my little filter that I built for this thing the
filter that I built for this thing the
filter that I built for this thing the hot glue just melted because this is
hot glue just melted because this is
hot glue just melted because this is getting too hot maybe I should use a
getting too hot maybe I should use a
getting too hot maybe I should use a little nitrogen to cool it down yeah
little nitrogen to cool it down yeah
little nitrogen to cool it down yeah it’s so so hot it’s just repelling right
it’s so so hot it’s just repelling right
it’s so so hot it’s just repelling right off that’s not even doing much so we’re
off that’s not even doing much so we’re
off that’s not even doing much so we’re at 21 and a half inches of mercury
at 21 and a half inches of mercury
at 21 and a half inches of mercury making very slow progress I’m not sure
making very slow progress I’m not sure
making very slow progress I’m not sure if we’re going to be able to do it my
if we’re going to be able to do it my
if we’re going to be able to do it my vacuum pumps going crazy spilling oil
vacuum pumps going crazy spilling oil
vacuum pumps going crazy spilling oil all over the place here well my hot glue
all over the place here well my hot glue
all over the place here well my hot glue is melting this thing’s just hanging by
is melting this thing’s just hanging by
is melting this thing’s just hanging by a thread right now I’ve got electrical
a thread right now I’ve got electrical
a thread right now I’ve got electrical tape holding this filter together so it
tape holding this filter together so it
tape holding this filter together so it doesn’t put oil clouds all over my
doesn’t put oil clouds all over my
doesn’t put oil clouds all over my workshop electricity and snow is it a
workshop electricity and snow is it a
workshop electricity and snow is it a good idea Wow
makes for some good snowball snow after
makes for some good snowball snow after warming up so at 22 inches of mercury
warming up so at 22 inches of mercury
warming up so at 22 inches of mercury now we’re making pretty slow progress
now we’re making pretty slow progress
now we’re making pretty slow progress but it is progressing if you look at the
but it is progressing if you look at the
but it is progressing if you look at the nitrogen now we’ve only got a little bit
nitrogen now we’ve only got a little bit
nitrogen now we’ve only got a little bit left a lot of it’s been vaporized so
left a lot of it’s been vaporized so
left a lot of it’s been vaporized so let’s keep this thing going until
let’s keep this thing going until
let’s keep this thing going until there’s absolutely no nitrogen left and
there’s absolutely no nitrogen left and
there’s absolutely no nitrogen left and then if we introduce the air back in if
then if we introduce the air back in if
then if we introduce the air back in if something does liquefy then we’ll know
something does liquefy then we’ll know
something does liquefy then we’ll know we did it because right now I’m having a
we did it because right now I’m having a
we did it because right now I’m having a really hard time seeing anything frozen
really hard time seeing anything frozen
really hard time seeing anything frozen down there oh there we go I think this
down there oh there we go I think this
down there oh there we go I think this is the last of the nitrogen it’s okay
is the last of the nitrogen it’s okay
is the last of the nitrogen it’s okay that’s it our nitrogen is completely
that’s it our nitrogen is completely
that’s it our nitrogen is completely gone and I don’t know about you but I
gone and I don’t know about you but I
gone and I don’t know about you but I didn’t really see anything frozen down
didn’t really see anything frozen down
didn’t really see anything frozen down there alright guys so I’m actually a
there alright guys so I’m actually a
there alright guys so I’m actually a little bit discouraged even pulling 22
little bit discouraged even pulling 22
little bit discouraged even pulling 22 inches of mercury in a vacuum chamber we
inches of mercury in a vacuum chamber we
inches of mercury in a vacuum chamber we were not able to successfully make solid
were not able to successfully make solid
were not able to successfully make solid nitrogen so right now this container is
nitrogen so right now this container is
nitrogen so right now this container is still under vacuum pressure if we open
still under vacuum pressure if we open
still under vacuum pressure if we open this valve it’ll let the air back in and
this valve it’ll let the air back in and
this valve it’ll let the air back in and we can take a container around
we can take a container around
we can take a container around [Music]
there we go so we’ve got them a bunch of
there we go so we’ve got them a bunch of vapor but we just got a big frosty glass
vapor but we just got a big frosty glass
vapor but we just got a big frosty glass there’s nothing in there at all no
there’s nothing in there at all no
there’s nothing in there at all no nitrogen no solid oops just very very
nitrogen no solid oops just very very
nitrogen no solid oops just very very cold now if I had a stronger pump
cold now if I had a stronger pump
cold now if I had a stronger pump perhaps we could have seen the nitrogen
perhaps we could have seen the nitrogen
perhaps we could have seen the nitrogen actually solidify I did get down to 22
actually solidify I did get down to 22
actually solidify I did get down to 22 inches of mercury which i think is a
inches of mercury which i think is a
inches of mercury which i think is a pretty good vacuum but it still wasn’t
pretty good vacuum but it still wasn’t
pretty good vacuum but it still wasn’t enough to get it to transition even when
enough to get it to transition even when
enough to get it to transition even when the nitrogen got down to a very very
the nitrogen got down to a very very
the nitrogen got down to a very very thin layer I thought for sure it was
thin layer I thought for sure it was
thin layer I thought for sure it was gonna flip over and it just didn’t it
gonna flip over and it just didn’t it
gonna flip over and it just didn’t it just evaporated so if you guys have any
just evaporated so if you guys have any
just evaporated so if you guys have any ideas on how we could actually make this
