hey guys we are back outside again today because today we’re experimenting with a
because today we’re experimenting with a
because today we’re experimenting with a relatively dangerous substance today
relatively dangerous substance today
relatively dangerous substance today we’re playing with propane now in our
we’re playing with propane now in our
we’re playing with propane now in our standard atmosphere propane is typically
standard atmosphere propane is typically
standard atmosphere propane is typically a gas but if you compress it into a
a gas but if you compress it into a
a gas but if you compress it into a bottle like this it actually liquefied
bottle like this it actually liquefied
bottle like this it actually liquefied under its own vapor pressure you shake
under its own vapor pressure you shake
under its own vapor pressure you shake one of these bottles and listen
one of these bottles and listen
one of these bottles and listen carefully you can actually hear liquid
carefully you can actually hear liquid
carefully you can actually hear liquid propane sloshing around inside the
propane sloshing around inside the
propane sloshing around inside the purpose of today’s experiment is to see
purpose of today’s experiment is to see
purpose of today’s experiment is to see if we can get that liquid propane out
if we can get that liquid propane out
if we can get that liquid propane out now if you remember back to a previous
now if you remember back to a previous
now if you remember back to a previous experiment we took a carbon dioxide fire
experiment we took a carbon dioxide fire
experiment we took a carbon dioxide fire extinguisher and sprayed it into a
extinguisher and sprayed it into a
extinguisher and sprayed it into a pillowcase to create a homemade dry ice
pillowcase to create a homemade dry ice
pillowcase to create a homemade dry ice and the process for doing that is very
and the process for doing that is very
and the process for doing that is very similar to how we’re going to extract
similar to how we’re going to extract
similar to how we’re going to extract our liquid propane here today now I want
our liquid propane here today now I want
our liquid propane here today now I want to give a shout out to my friend Kevin
to give a shout out to my friend Kevin
to give a shout out to my friend Kevin he’s the backyard scientist and before
he’s the backyard scientist and before
he’s the backyard scientist and before he started playing with liquid nitrogen
he started playing with liquid nitrogen
he started playing with liquid nitrogen he used liquid propane and the way he
he used liquid propane and the way he
he used liquid propane and the way he would do that was by modifying the torch
would do that was by modifying the torch
would do that was by modifying the torch for the propane tank itself and sticking
for the propane tank itself and sticking
for the propane tank itself and sticking it upside down into glass so we’re gonna
it upside down into glass so we’re gonna
it upside down into glass so we’re gonna make that modification here today I’m
make that modification here today I’m
make that modification here today I’m going to show you step-by-step how it
going to show you step-by-step how it
going to show you step-by-step how it works because of the pressure the
works because of the pressure the
works because of the pressure the propane is putting on the inside of the
propane is putting on the inside of the
propane is putting on the inside of the tank it wants to escape and so by
tank it wants to escape and so by
tank it wants to escape and so by opening the valve counterclockwise more
opening the valve counterclockwise more
opening the valve counterclockwise more propane can shoot out and by turning it
propane can shoot out and by turning it
propane can shoot out and by turning it clockwise it restricts the flow and
clockwise it restricts the flow and
clockwise it restricts the flow and limits the flame eventually shutting it
limits the flame eventually shutting it
limits the flame eventually shutting it off now this is kind of interesting if
off now this is kind of interesting if
off now this is kind of interesting if you look down on the tip of the nozzle
you look down on the tip of the nozzle
you look down on the tip of the nozzle you’ll see a little wire mesh in there
you’ll see a little wire mesh in there
you’ll see a little wire mesh in there and the purpose of that is to stop
and the purpose of that is to stop
and the purpose of that is to stop flashbacks gas can burn freely outside
flashbacks gas can burn freely outside
flashbacks gas can burn freely outside of the nozzle but it doesn’t work its
of the nozzle but it doesn’t work its
of the nozzle but it doesn’t work its way back inside because that wire mesh
way back inside because that wire mesh
way back inside because that wire mesh stops it what’s really interesting is if
stops it what’s really interesting is if
stops it what’s really interesting is if we remove the sheathing from the nozzle
we remove the sheathing from the nozzle
we remove the sheathing from the nozzle here the flame actually goes out and if
here the flame actually goes out and if
here the flame actually goes out and if we try and relight that again it won’t
we try and relight that again it won’t
we try and relight that again it won’t actually work the hole in the tip here
actually work the hole in the tip here
actually work the hole in the tip here is so small it’s shooting a gas out like
is so small it’s shooting a gas out like
is so small it’s shooting a gas out like a jet and so we’re not able to light it
a jet and so we’re not able to light it
a jet and so we’re not able to light it even with a barbecue igniter it whisks
even with a barbecue igniter it whisks
even with a barbecue igniter it whisks the heat away so quickly there’s no time
the heat away so quickly there’s no time
the heat away so quickly there’s no time for ignition let’s make the hole bigger
for ignition let’s make the hole bigger
for ignition let’s make the hole bigger so here’s the basic idea I got myself a
so here’s the basic idea I got myself a
so here’s the basic idea I got myself a hacksaw and a drill with a 932 inch
hacksaw and a drill with a 932 inch
hacksaw and a drill with a 932 inch drill bit we’re going to use the hacksaw
drill bit we’re going to use the hacksaw
drill bit we’re going to use the hacksaw to cut the tip off the torch and the
to cut the tip off the torch and the
to cut the tip off the torch and the drill bit to hollow it out and there we
drill bit to hollow it out and there we
drill bit to hollow it out and there we have it as easy as that we’ve got an
have it as easy as that we’ve got an
have it as easy as that we’ve got an instant homemade propane skewer
instant homemade propane skewer
instant homemade propane skewer [Music]
[Music]
[Music] [Applause]
[Applause]
[Applause] the hole on this nozzle is exponentially
the hole on this nozzle is exponentially
the hole on this nozzle is exponentially wider than the factory version and so
wider than the factory version and so
wider than the factory version and so when we open the valve now there’s
when we open the valve now there’s
when we open the valve now there’s nothing to restrict the flow so the
nothing to restrict the flow so the
nothing to restrict the flow so the nozzle cools down quickly and begins
nozzle cools down quickly and begins
nozzle cools down quickly and begins dripping liquid propane now I’m going to
dripping liquid propane now I’m going to
dripping liquid propane now I’m going to try something now that you probably
try something now that you probably
try something now that you probably shouldn’t try at home I’m going to open
shouldn’t try at home I’m going to open
shouldn’t try at home I’m going to open this valve all the way and touch it off
this valve all the way and touch it off
this valve all the way and touch it off with a barbecue tonight er just want to
with a barbecue tonight er just want to
with a barbecue tonight er just want to see what happens is anything gonna
see what happens is anything gonna
see what happens is anything gonna happen there we go
happen there we go
happen there we go how sweet
[Applause]
[Applause] now you might be wondering why the flame
now you might be wondering why the flame
now you might be wondering why the flame didn’t travel back into the bottle and
didn’t travel back into the bottle and
didn’t travel back into the bottle and make this thing explode and here’s why
make this thing explode and here’s why
make this thing explode and here’s why we know that the fire triangle says
we know that the fire triangle says
we know that the fire triangle says three things need to be present in order
three things need to be present in order
three things need to be present in order for combustion to happen we need to have
for combustion to happen we need to have
for combustion to happen we need to have an ignition source we need to have fuel
an ignition source we need to have fuel
an ignition source we need to have fuel and we need to have oxygen but there’s
and we need to have oxygen but there’s
and we need to have oxygen but there’s no oxygen in the bottle so there’s no
no oxygen in the bottle so there’s no
no oxygen in the bottle so there’s no way for combustion to take place until
way for combustion to take place until
way for combustion to take place until it travels out of the nozzle it mixes
it travels out of the nozzle it mixes
it travels out of the nozzle it mixes with the oxygen in the air but saying
with the oxygen in the air but saying
with the oxygen in the air but saying that this still isn’t an experiment I
that this still isn’t an experiment I
that this still isn’t an experiment I can recommend for anyone else all right
can recommend for anyone else all right
can recommend for anyone else all right now for the fun part the backyard
now for the fun part the backyard
now for the fun part the backyard scientists found that if we crank this
scientists found that if we crank this
scientists found that if we crank this valve fully open and turn it upside down
valve fully open and turn it upside down
valve fully open and turn it upside down and leave it in the glass all we have to
and leave it in the glass all we have to
and leave it in the glass all we have to do is give it a few minutes and the
do is give it a few minutes and the
do is give it a few minutes and the glass will fill itself up so we have our
glass will fill itself up so we have our
glass will fill itself up so we have our propane with our modified tip we have a
propane with our modified tip we have a
propane with our modified tip we have a glass so let’s go ahead and put the two
glass so let’s go ahead and put the two
glass so let’s go ahead and put the two together and see if it really works
together and see if it really works
together and see if it really works [Music]
it is so now that we got our glass
it is so now that we got our glass filling up with propane let me tell you
filling up with propane let me tell you
filling up with propane let me tell you about some of the characteristics of
about some of the characteristics of
about some of the characteristics of propane itself we already know that
propane itself we already know that
propane itself we already know that propane is normally a gas but if you
propane is normally a gas but if you
propane is normally a gas but if you compress it and stick it in a
compress it and stick it in a
compress it and stick it in a pressurized steel container it will
pressurized steel container it will
pressurized steel container it will actually carry as a liquid the liquid
actually carry as a liquid the liquid
actually carry as a liquid the liquid itself is pretty cold but maybe not as
itself is pretty cold but maybe not as
itself is pretty cold but maybe not as cold as you might think it’s nowhere
cold as you might think it’s nowhere
cold as you might think it’s nowhere near the boiling point of liquid
near the boiling point of liquid
near the boiling point of liquid nitrogen
nitrogen
nitrogen propane boils at minus 40 degrees
propane boils at minus 40 degrees
propane boils at minus 40 degrees Fahrenheit that’s about minus 42 degrees
Fahrenheit that’s about minus 42 degrees
Fahrenheit that’s about minus 42 degrees Celsius but the amazing thing is it
Celsius but the amazing thing is it
Celsius but the amazing thing is it won’t freeze until it hits minus 306 now
won’t freeze until it hits minus 306 now
won’t freeze until it hits minus 306 now even though it’s far from being as cold
even though it’s far from being as cold
even though it’s far from being as cold as liquid nitrogen making contact with
as liquid nitrogen making contact with
as liquid nitrogen making contact with your bare skin can cause frostbite but
your bare skin can cause frostbite but
your bare skin can cause frostbite but the bigger concern here is this liquid
the bigger concern here is this liquid
the bigger concern here is this liquid is flammable meaning if you got it near
is flammable meaning if you got it near
is flammable meaning if you got it near a flame or a spark it could go off and
a flame or a spark it could go off and
a flame or a spark it could go off and cause a lot of damage
cause a lot of damage
cause a lot of damage propane vapors are actually heavier than
propane vapors are actually heavier than
propane vapors are actually heavier than air which means they’re not going to
air which means they’re not going to
air which means they’re not going to float away into the atmosphere they will
float away into the atmosphere they will
float away into the atmosphere they will sink down into the corners of the room
sink down into the corners of the room
sink down into the corners of the room so if you’re working in a very confined
so if you’re working in a very confined
so if you’re working in a very confined space with propane and there’s a small
space with propane and there’s a small
space with propane and there’s a small chance you could push out all the air
chance you could push out all the air
chance you could push out all the air and suffocate you there we go guys it’s
and suffocate you there we go guys it’s
and suffocate you there we go guys it’s been about six or seven minutes our
been about six or seven minutes our
been about six or seven minutes our glass is about halfway full and you can
glass is about halfway full and you can
glass is about halfway full and you can see the stuff is cold because frost is
see the stuff is cold because frost is
see the stuff is cold because frost is forming on the outside of the glass
forming on the outside of the glass
forming on the outside of the glass itself there are caps rate has decreased
itself there are caps rate has decreased
itself there are caps rate has decreased quite a bit I think that’s because most
quite a bit I think that’s because most
quite a bit I think that’s because most of the liquid is out and we’re just
of the liquid is out and we’re just
of the liquid is out and we’re just blowing bubbles at this point the
blowing bubbles at this point the
blowing bubbles at this point the interesting thing is our tank is still
interesting thing is our tank is still
interesting thing is our tank is still going it’s slowed down but it’s still
going it’s slowed down but it’s still
going it’s slowed down but it’s still pumping out liquid propane look at this
pumping out liquid propane look at this
pumping out liquid propane look at this down here so let’s take it apart and
down here so let’s take it apart and
down here so let’s take it apart and play with the liquid itself
so there we go guys the goal of this
so there we go guys the goal of this experiment was to extract liquid propane
experiment was to extract liquid propane
experiment was to extract liquid propane and I think you could say we’ve done
and I think you could say we’ve done
and I think you could say we’ve done that successfully but there are a couple
that successfully but there are a couple
that successfully but there are a couple more quick experiments I want to try
more quick experiments I want to try
more quick experiments I want to try before we go first off what will a
before we go first off what will a
before we go first off what will a marshmallow do soaked in liquid propane
marshmallow do soaked in liquid propane
marshmallow do soaked in liquid propane and what will happen if we light it off
and what will happen if we light it off
and what will happen if we light it off okay here we go dunk number one
[Music]
[Music] oh you hear that
oh you hear that
oh you hear that sorry frozen solid cool
look how hard that is that’s cool that
look how hard that is that’s cool that froze pretty quick let’s leave it in
froze pretty quick let’s leave it in
froze pretty quick let’s leave it in there for about another minute yeah
there for about another minute yeah
there for about another minute yeah that’s about a minute let’s take it out
that’s about a minute let’s take it out
that’s about a minute let’s take it out and smash it oh that’s hard nice
yeah it’s like really crispy on the
yeah it’s like really crispy on the outside but still a bit of gooey on the
outside but still a bit of gooey on the
outside but still a bit of gooey on the inside maybe I should have left that
inside maybe I should have left that
inside maybe I should have left that little bit longer because now I just
little bit longer because now I just
little bit longer because now I just made a mess everywhere let’s try that
made a mess everywhere let’s try that
made a mess everywhere let’s try that again but this time I’m going to light
again but this time I’m going to light
again but this time I’m going to light it off
it off
it off all right that’s been about a minute you
all right that’s been about a minute you
all right that’s been about a minute you can see this thing is actually so crispy
can see this thing is actually so crispy
can see this thing is actually so crispy it chips off I’m going to light it up
it chips off I’m going to light it up
it chips off I’m going to light it up away from the propane
away from the propane
away from the propane [Music]
[Music]
[Music] that burned out pretty quickly and even
that burned out pretty quickly and even
that burned out pretty quickly and even scorch the whole thing so marshmallows
scorch the whole thing so marshmallows
scorch the whole thing so marshmallows in liquid propane kind of cool but
in liquid propane kind of cool but
in liquid propane kind of cool but there’s one bigger question on my mind
there’s one bigger question on my mind
there’s one bigger question on my mind that I’d really like to see the results
that I’d really like to see the results
that I’d really like to see the results – what would happen if we touched an
– what would happen if we touched an
– what would happen if we touched an open flame to a glass of liquid propane
open flame to a glass of liquid propane
open flame to a glass of liquid propane what the whole thing explode would it go
what the whole thing explode would it go
what the whole thing explode would it go up in a big fireball or would it just
up in a big fireball or would it just
up in a big fireball or would it just sit there and casually burn you and I
sit there and casually burn you and I
sit there and casually burn you and I both know there’s only one way to find
both know there’s only one way to find
both know there’s only one way to find out now I’m not exactly sure what’s
out now I’m not exactly sure what’s
out now I’m not exactly sure what’s going to happen so I came out here to a
going to happen so I came out here to a
going to happen so I came out here to a big cement pad I think I’m just going to
big cement pad I think I’m just going to
big cement pad I think I’m just going to set this thing down and throw lit
set this thing down and throw lit
set this thing down and throw lit matches into it so we can ignite it from
matches into it so we can ignite it from
matches into it so we can ignite it from a distance sounds safe right here we go
a distance sounds safe right here we go
a distance sounds safe right here we go mom I’m sure ooh oh that was so close
there we go yes okay so that wasn’t
there we go yes okay so that wasn’t incredibly dangerous looks like it’s
incredibly dangerous looks like it’s
incredibly dangerous looks like it’s still burning it is so there’s a little
still burning it is so there’s a little
still burning it is so there’s a little flame in there but that’s not super
flame in there but that’s not super
flame in there but that’s not super dangerous at all in fact you can barely
dangerous at all in fact you can barely
dangerous at all in fact you can barely even see the flame if you look closely
even see the flame if you look closely
even see the flame if you look closely you can actually see my match floating
you can actually see my match floating
you can actually see my match floating at the bottom what if I roll it around a
at the bottom what if I roll it around a
at the bottom what if I roll it around a little bit oh wow got the little bits of
little bit oh wow got the little bits of
little bit oh wow got the little bits of marshmallow on the side they’re burning
marshmallow on the side they’re burning
marshmallow on the side they’re burning Wow so it didn’t explode and this
Wow so it didn’t explode and this
Wow so it didn’t explode and this actually makes sense because if you
actually makes sense because if you
actually makes sense because if you think about it this whole container is
think about it this whole container is
think about it this whole container is filled with propane like the bottle
filled with propane like the bottle
filled with propane like the bottle itself there’s not much oxygen here so
itself there’s not much oxygen here so

it doesn’t actually ignite until it gets
it doesn’t actually ignite until it gets up here where it meets the atmosphere
up here where it meets the atmosphere
up here where it meets the atmosphere but if I shake it around I can agitate
but if I shake it around I can agitate
but if I shake it around I can agitate that and create a lot more gas venting
that and create a lot more gas venting
that and create a lot more gas venting off I get this thing closed with bigger

off I get this thing closed with bigger if we were to pour the stuff out on the
if we were to pour the stuff out on the
if we were to pour the stuff out on the concrete it would have a lot more
concrete it would have a lot more
concrete it would have a lot more surface area and probably create a much

very cool let’s go ahead and summarize
very cool let’s go ahead and summarize what we just learned here today we know
what we just learned here today we know
what we just learned here today we know that propane is a gas in its normal

all the way tipped it upside down a cup
all the way tipped it upside down a cup and left it for about six minutes where
and left it for about six minutes where
and left it for about six minutes where we extracted all the liquid propane and
we extracted all the liquid propane and
we extracted all the liquid propane and got half a glass or about one cup
got half a glass or about one cup
got half a glass or about one cup we tried freezing marshmallows to see
we tried freezing marshmallows to see
we tried freezing marshmallows to see what they would do and found they got
what they would do and found they got
what they would do and found they got really crispy on the outside but unless
really crispy on the outside but unless
really crispy on the outside but unless they’re soaked longer they stay pretty
they’re soaked longer they stay pretty
they’re soaked longer they stay pretty gummy on the inside
gummy on the inside
gummy on the inside and finally we tried lighting matches
and finally we tried lighting matches
and finally we tried lighting matches and throwing them into an open container
and throwing them into an open container
and throwing them into an open container of liquid propane to see what happened

of liquid propane to see what happened where we discover all that really
where we discover all that really
where we discover all that really happens is it just slowly burns off the
happens is it just slowly burns off the
happens is it just slowly burns off the top as its able to mix with the air so
