today we’re gonna test what happens if
you put burning charcoal into a vacuum
chamber are they gonna keep burning will
they go out let’s find out what changes
you tuber danta sharp asked what would
happen if we put hot coals in a vacuum
chamber
dontoh we don’t know and so we are going
to find out we’ve got some hot coals
we’ve got a vacuum chamber let’s see
what they do we got a camera and a light
going inside let’s see what happens when
there’s a tornado in there we should
film all sorts of things inside vacuum
chambers I see glowing with orange
starting to show up on the edge of those
coals oh yeah that’s picking up they’re
there’s charcoal in one type of vacuum
chamber now I’m sure what you meant was
putting in a low pressure vacuum chamber
and of course we’re gonna do that too
let’s talk about how as a control we are
just gonna put some unlit charcoal into
our chamber to see how that’s different
my prediction is that we won’t be able
to see any change nothing will move
we’ll just have the charcoal sitting in
there and that’s okay the point of this
isn’t actually to see what happens in
low pressure it’s to see what happens in
low oxygen and once those are burning
that should make a difference now to me
that didn’t look like a whole lot
changed which as I said is what we
expected unburn intention vacuum now
let’s test burning and like I said we’re
gonna do this in a few different ways
we’re gonna have burning charcoal down
in our vacuum chamber sitting on top of
some kayo wool so that the heat isn’t
directly transferred into the glass
we’re gonna take another chamber same
size and shape and we’re gonna put some
more charcoal in that and that one we’re
also going to add a bit of dry ice
hopefully that will just flood the
entire inside with carbon dioxide and we
can see the difference between a non
oxygen environment and a carbon dioxide
environment then we’ll have one final
set of charcoal off the side also not in
a jar it will be exposed to the air but
we’re gonna use our shop vac to blow air
onto it so it has sort of fun extra
oxygen enriched environment I figure
that will give us a good spread from
high oxygen down to No or opposing
oxygen environments we’ll see which
charcoals burn the fastest and we’ve got
a temperature gun to see what the
difference is in heat here’s the basic
idea we’re gonna take some burning
charcoal we’ll put it in a vacuum
chamber another chamber with carbon
dioxide a pile of charcoal just sitting
in the air and some more charcoal with
added air being blown on it one idea
that we did have was actually to use
pure oxygen to show what that did with
the charcoal there’s a couple of reasons
we’re not going to do that one this is
not a very common situation the air
around us is actually not a pure oxygen
environment most of its nitrogen with
some oxygen carbon dioxide and other
elements floating around in it the other
reason is that these tanks aren’t free
and we actually go through them really
quickly while trying this experiment out
we are hoping to let things run a little
bit longer than that but we did want to
show you what happens when we put a pure
oxygen stream onto one of these burning
you can already see how much it heats
the coal up and gets it burning better
but watch what happens is I get the
oxygen even closer making it more
this wasn’t a brand-new canister but it
is now empty like I said it goes through
it really quickly look at that where I
was blowing the oxygen right in it just
it burned so well and intensely that is
just tunneled right down through and
also through spark slaw I think it
burned me through my glove a little bit
okay now we’re gonna fill this chamber
with carbon dioxide by using the dry ice
so we’re just gonna let this overflow
down into that chamber a little bit of
course now the GoPro can’t see anything
a lot of paper in there piece of dry ice
down in there as well at that point
there should be almost exclusively
carbon dioxide in that chamber without
really any oxygen or nitrogen or any of
our thermometer is currently showing our
outside charcoal at 850 degrees
approximately that’s in Fahrenheit
that’s warm okay this puts out a lot of
air we’re gonna be blowing that on the
charcoal and it’s going to start glowing
orange like immediately
all right quick update if you remember
we are getting about eight hundred
eighty degrees Fahrenheit with the
charcoal just sitting there let’s look
at what it is with the charcoal we’ve
been hitting with the air 13-under
degrees Fahrenheit we work for a second
he was at 39 it’s already dropping but
that was a hundred degrees Fahrenheit
[Music]
it’s been 10 maybe 12 minutes that we’ve
been letting all four of these types run
and we want to do a temperature update
sorry about the noise the vacuum is
running we do want to let it keep going
but we’re going to do a check oh no we
lost them well let’s do a check of this
one all right at the moment this tiny
one is only registering 11 of 1200 per
second before when all three were
stacked this registered at over 1,500
degrees Fahrenheit so we’re gonna put
that at 1500 because those just barely
got blown over let’s check the ones it’s
just sitting out
all right between 790 and 850 is kind of
what we’re getting here our carbon
dioxide 287
Wow that is 220 down there that’s like
barely hot enough to boil water this has
gone way down so under 300 definitely we
are gonna let air back into this one
we’re trying to do it slowly so it
doesn’t fan the charcoal too much 255 so
like the carbon dioxide environments
this is really suffering on heat we’ve
let some hot coals sit out in the open
air for a while and we’ve gotten to the
point where they’re really falling apart
they’re mostly native ash so I figure
that’s a good time to compare how they
are to the ones in our carbon dioxide
chamber and our vacuum chamber let’s
take a look most of our mass is gone
from those they’ve burned down most of
the ash so let’s do a comparison we
already looked at the ones that we’re
blowing with a vacuum and those just it
took 10 minutes maybe and they were just
down to this size or maybe even smaller
gotta say preliminary ly our charcoal in
here doesn’t look like it’s been burning
very much compared to this it’s about
the size that they went in so we’ve got
hours and degrees surface temperature on
these ones 80 degree surface temperature
in these woods all right but I’m gonna
risk this and just grab it with my
fingers that’s I mean that’s just out
there is no burning left to this the
carbon dioxide put that charcoal out
completely there’s it’s not on fire it’s
I wouldn’t call that a hot coal anymore
that’s just leftover charcoal no longer
burning all right let’s check our vacuum
chamber
also 92 and that is really similar to
the carbon dioxide one I’m gonna risk it
again pull that out this one feels a
tiny bit warmer just like a couple of
degrees like it does feel slightly warm
compared to the dry ice ones which just
didn’t feel warm at all they felt fairly
cool but again no danger in me holding
this they’re not hot they are not gonna
burn me nothing is glowing there’s no
Ember left those are out dontoh sharp
thank you for your suggestion of putting
hot coals in a vacuum chamber I think we
learned some interesting things it was
really cool to see what it did guys you
know that’s not all we’ve always got
more for you to see check out that box
up at the top it’s gonna take you to our
last video you should go check that out
the other box is going to show you what
YouTube thinks you should be watching
now and if you hit this bomb here in the
middle you’ll be subscribed to the
channel that way you’re not going to
miss a cool video don’t forget to ring
that Bell and we’ll see you in the next
one talk to you then [Music]
