what’s up guys welcome back to the king of random kitchen you guys have been
of random kitchen you guys have been
of random kitchen you guys have been asking for it you guys have been waiting
asking for it you guys have been waiting
asking for it you guys have been waiting for it so in today’s episode I’m finally
for it so in today’s episode I’m finally
for it so in today’s episode I’m finally doing it I’m teaching you how to make
doing it I’m teaching you how to make
doing it I’m teaching you how to make liquid nitrogen
liquid nitrogen
liquid nitrogen I’ve been really hesitant to put out a
I’ve been really hesitant to put out a
I’ve been really hesitant to put out a video on how I make liquid nitrogen
video on how I make liquid nitrogen
video on how I make liquid nitrogen because honestly my setup isn’t very
because honestly my setup isn’t very
because honestly my setup isn’t very professional it’s all jury-rigged
professional it’s all jury-rigged
professional it’s all jury-rigged together and it doesn’t look great but
together and it doesn’t look great but
together and it doesn’t look great but it does work well I’m starting to
it does work well I’m starting to
it does work well I’m starting to realize you guys don’t really care what
realize you guys don’t really care what
realize you guys don’t really care what it looks like you’re more interested in
it looks like you’re more interested in
it looks like you’re more interested in how its functions so that’s what we’re
how its functions so that’s what we’re
how its functions so that’s what we’re getting into today now if you go outside
getting into today now if you go outside
getting into today now if you go outside and take a deep breath you’re filling
and take a deep breath you’re filling
and take a deep breath you’re filling your lungs with about 20% oxygen 79%
your lungs with about 20% oxygen 79%
your lungs with about 20% oxygen 79% nitrogen and 1% other gases now the
nitrogen and 1% other gases now the
nitrogen and 1% other gases now the first step in making liquid nitrogen is
first step in making liquid nitrogen is
first step in making liquid nitrogen is just to take the regular atmosphere and
just to take the regular atmosphere and
just to take the regular atmosphere and compress it into some kind of a
compress it into some kind of a
compress it into some kind of a container that can hold it under
container that can hold it under
container that can hold it under pressure
pressure
pressure once it’s under pressure we can pass it
once it’s under pressure we can pass it
once it’s under pressure we can pass it through a nitrogen membrane which will
through a nitrogen membrane which will
through a nitrogen membrane which will separate the oxygen and the other gases
separate the oxygen and the other gases
separate the oxygen and the other gases leaving pure nitrogen gas behind but
leaving pure nitrogen gas behind but
leaving pure nitrogen gas behind but there’s one other problem the nitrogen
there’s one other problem the nitrogen
there’s one other problem the nitrogen might have some moisture associated with
might have some moisture associated with
might have some moisture associated with it and we don’t want any moisture so the
it and we don’t want any moisture so the
it and we don’t want any moisture so the next step is to pass that gas through
next step is to pass that gas through
next step is to pass that gas through some kind of mechanism that dries it out
some kind of mechanism that dries it out
some kind of mechanism that dries it out now in one of the secret compartments of
now in one of the secret compartments of
now in one of the secret compartments of my room I have this nitrogen generator
my room I have this nitrogen generator
my room I have this nitrogen generator that does all that for me and I really
that does all that for me and I really
that does all that for me and I really have to give credit where credit’s due
have to give credit where credit’s due
have to give credit where credit’s due to my friend Chris Roberts who really
to my friend Chris Roberts who really
to my friend Chris Roberts who really made all this possible he’s the one that
made all this possible he’s the one that
made all this possible he’s the one that located all the items he sourced all the
located all the items he sourced all the
located all the items he sourced all the equipment he helped put it all together
equipment he helped put it all together
equipment he helped put it all together and he helped it get to the functioning
and he helped it get to the functioning
and he helped it get to the functioning state that it is today now once we’ve
state that it is today now once we’ve
state that it is today now once we’ve got the clean dry nitrogen gas we need a
got the clean dry nitrogen gas we need a
got the clean dry nitrogen gas we need a place to store it
place to store it
place to store it my friend Chris went down to Harbor
my friend Chris went down to Harbor
my friend Chris went down to Harbor Freight and pick up a little tank for
Freight and pick up a little tank for
Freight and pick up a little tank for about 20 bucks that we use to store that
about 20 bucks that we use to store that
about 20 bucks that we use to store that nitrogen gas under pressure and we added
nitrogen gas under pressure and we added
nitrogen gas under pressure and we added a little regulator so we can turn a knob
a little regulator so we can turn a knob
a little regulator so we can turn a knob and regulate how much gas flows out and
and regulate how much gas flows out and
and regulate how much gas flows out and now it might seem a little bit too
now it might seem a little bit too
now it might seem a little bit too simple but that’s half the battle in
simple but that’s half the battle in
simple but that’s half the battle in making liquid nitrogen
making liquid nitrogen
making liquid nitrogen once we’ve got dry nitrogen seeping out
once we’ve got dry nitrogen seeping out
once we’ve got dry nitrogen seeping out at about 1 psi all we have to do is get
at about 1 psi all we have to do is get
at about 1 psi all we have to do is get it cold enough that it liquefies and
it cold enough that it liquefies and
it cold enough that it liquefies and this is where we bring in the helium
this is where we bring in the helium
this is where we bring in the helium compressor now helium compressor unit is
compressor now helium compressor unit is
compressor now helium compressor unit is basically just a glorified air
basically just a glorified air
basically just a glorified air conditioning unit the whole purpose of
conditioning unit the whole purpose of
conditioning unit the whole purpose of this existence is to get colder than the
this existence is to get colder than the
this existence is to get colder than the boiling point of nitrogen now helium has
boiling point of nitrogen now helium has
boiling point of nitrogen now helium has a boiling point around minus 452 degrees
a boiling point around minus 452 degrees
a boiling point around minus 452 degrees Fahrenheit which is way below the
Fahrenheit which is way below the
Fahrenheit which is way below the boiling point of liquid nitrogen
boiling point of liquid nitrogen
boiling point of liquid nitrogen I think it’s Boyle’s law that says if
I think it’s Boyle’s law that says if
I think it’s Boyle’s law that says if you take a gas and compress it and then
you take a gas and compress it and then
you take a gas and compress it and then let it cool back down if you rapidly
let it cool back down if you rapidly
let it cool back down if you rapidly expand it that gas will get very very
expand it that gas will get very very
expand it that gas will get very very cold and because we’re using helium we
cold and because we’re using helium we
cold and because we’re using helium we can compress it cool that gas down and
can compress it cool that gas down and
can compress it cool that gas down and rapidly expand it to a temperature
rapidly expand it to a temperature
rapidly expand it to a temperature that’s lower than the boiling point of
that’s lower than the boiling point of
that’s lower than the boiling point of liquid night
liquid night
liquid night so now that you’ve got the basic concept
so now that you’ve got the basic concept
so now that you’ve got the basic concept let me explain in a little bit more
let me explain in a little bit more
let me explain in a little bit more detail how a helium compressor works
detail how a helium compressor works
detail how a helium compressor works it’s charged up with helium gas in a
it’s charged up with helium gas in a
it’s charged up with helium gas in a closed-loop system the helium gas is
closed-loop system the helium gas is
closed-loop system the helium gas is compressed where it keeps up
compressed where it keeps up
compressed where it keeps up tremendously and we need some kind of a
tremendously and we need some kind of a
tremendously and we need some kind of a system to cool it down which I’ll talk
system to cool it down which I’ll talk
system to cool it down which I’ll talk about in just a minute but once it is
about in just a minute but once it is
about in just a minute but once it is cooled down it can travel to the cryo
cooled down it can travel to the cryo
cooled down it can travel to the cryo head where it’s rapidly expanded and
head where it’s rapidly expanded and
head where it’s rapidly expanded and cooled down to a temperature lower than
cooled down to a temperature lower than
cooled down to a temperature lower than the boiling point of nitrogen so what
the boiling point of nitrogen so what
the boiling point of nitrogen so what would happen if we had a surface that
would happen if we had a surface that
would happen if we had a surface that was colder than the boiling point of
was colder than the boiling point of
was colder than the boiling point of liquid nitrogen and we had a small vapor
liquid nitrogen and we had a small vapor
liquid nitrogen and we had a small vapor of nitrogen gas blowing at it that’s
of nitrogen gas blowing at it that’s
of nitrogen gas blowing at it that’s right it’s going to condense and is
right it’s going to condense and is
right it’s going to condense and is going to form small droplets and drip
going to form small droplets and drip
going to form small droplets and drip down to ground now if we’re able to
down to ground now if we’re able to
down to ground now if we’re able to catch those droplets into some kind of a
catch those droplets into some kind of a
catch those droplets into some kind of a glorified thermos a Dewar if you will
glorified thermos a Dewar if you will
glorified thermos a Dewar if you will then theoretically over time those
then theoretically over time those
then theoretically over time those droplets would add up and produce
droplets would add up and produce
droplets would add up and produce bucketfuls of liquid nitrogen and that’s
bucketfuls of liquid nitrogen and that’s
bucketfuls of liquid nitrogen and that’s it guys that is exactly how we make
