workshop not too long ago we showed you
how to use liquid nitrogen to turn soda
into a delicious Slurpee at the end of
that video I said I might want to try it
again using dry ice because the liquid
nitrogen pulled all of the carbonation
out of our soda and I was curious if dry
ice would put carbonation back into the
soda as it froze it well today we’re
gonna try a few different varieties of
that we’ll see if we can get a Slurpee
that’s still nice and fizzy we’ve got
our soda we’ve got our dry ice let’s get
started to start let’s pour a measure of
our soda into our Bowl then break up
some medium sized chunks of our dry ice
put that in and stir it and see if we
[Music]
that’s about the size about the size I
want get these chunks in there just kind
of stir it up and see if we can get it
to start freezing into a slush I don’t
really have a good sense for how long
this should take I’ve never tried just
chunks of dry ice and soda before to see
how long it takes to solidify we’re
getting somewhere
getting some slush in there you want to
see interesting how it’s sort of
freezing with a pebbled texture to it
it’s not going evenly everywhere and I’m
not sure what’s causing the difference
turning into a good slushy though the
question is whether enough of the carbon
dioxide coming off of the dry ice has
been dissolved into the slushy as it’s
mixing up and freezing to really give us
a carbonated fizzy result when we eat
this alright I think that’s a pretty
good freeze on here try and scoop it
from the bowl into our cup and of course
we want to avoid scooping any chunks of
dry ice into our cup we don’t want to
eat those
just want them to cool everything down
and add a little bit of carbonation
hopefully there we go a homemade Slurpee
it took five or six minutes of stirring
up I would say and overall it works
pretty well it’s a good texture tastes
[Music]
it’s not very fizzy there might be a
little bit but there are a couple other
things I still want to try to see if
they give us a little bit more fizz for
our next test we’re gonna take a similar
quantity of dry ice but then we’re gonna
throw it in a blender and turn it into a
very fine powder we’ll see what happens
if we mix that powder in with our soda
and see if we get a different texture a
different freeze time and if it’s more
or less carbonated than our first one
our blender actually seals up airtight
when it’s closed so to keep the co2
pressure from building up inside we’re
gonna drill a small hole into the side
of the cup
[Applause]
[Music]
[Applause]
alright let’s take our soda dump in our
blend it up co2 it’s not a complete
powder but there is a lot of powder in
there
Wow that is definitely freezing way way
faster
in fact it’s frozen pretty much all of
the way already with a bunch of co2 left
over in it and then of course we don’t
want to eat the dry ice which is one of
the concerns I had with this method is
that we’re putting powdered dry ice into
the soda if the soda contains a little
bits of dry ice that haven’t turned back
into gas then the dry ice would just go
in your mouth and started to eat it
we don’t want to do that wow that froze
it so so much faster like I said it took
five or six minutes with the chunks of
dry ice just constantly stirring with
the powdered stuff it just immediately
almost started freezing together a lot
more surface area alright here we go
we’ve got our considerably more frozen
slushy at this point I think we’ve maybe
even gone past the texture of slushy and
into I don’t know it’s kind of like the
fruit flavored dippin dots almost it’s
not quite that frozen and it’s not that
well defined you can’t see the
individual particles that much but it is
almost powdery it’s so frozen alright
I’ve got a spoonful of this I’m trying
to make sure there’s no vapor rising off
of it because I don’t want any dry ice
chunks in my mouth
freezing onto my tongue that sounds
uncomfortable let’s try this
[Music]
still surprisingly little in terms of
FIDs I don’t know I think maybe carbon
dioxide doesn’t dissolved well into
liquid when it’s this cold
once it starts freezing they might
squeeze all of the carbon dioxide out of
it and just not hold any fizz life well
there is another variety we want to try
we’ve still got some dry ice and as
we’ve seen in the past if we freeze our
dry ice in liquid nitrogen it becomes
extremely brittle to the point where we
can just sort of break it apart so I’m
going to try taking some dry ice
freezing it in liquid nitrogen then
breaking it apart into a dust and then
using that to freeze our soda let’s give
it a shot all right we’ve got some
liquid nitrogen in our bowl let’s add a
chunk of dry ice to it and let it really
get cold case dry ice isn’t cold enough
[Music]
ha it just falls right to pieces now all
right let’s see how soft this stuff is
and it does come apart really easily
comparison normal dry ice
nothing super frozen dry ice still hurt
a little bit but it broke out not even
gonna blend this I’m just gonna put the
lid on and then shake it up that
powdered most of it we’ve got our little
jet of carbon dioxide gas flying out
here in the hole alright let’s pour off
some soda and then add our powdered
carbon dioxide to it well I would say an
even faster freeze time than the normal
powdered dry ice that goes so quickly
it’s still so cold I’m just gonna pour
more soda on top of it yeah with the
rest of the dry ice in there compared to
just a bottle of soda this seems like it
has so much volume it’s got so much air
and carbon dioxide added into it it just
seemed a lot bigger kind of wonder how
much this could keep freezing we got a
whole bottle of soda and it’s you know
it froze all of it no problem I think
we’re gonna add more from a different
bottle and see if we can get it to
or I’m gonna keep going until it doesn’t
freeze it anymore or until I run out of
bottles of soda
it’s so weird this is the same amount of
dry ice for the most part as what went
into our first batch with the larger
chunks of dry ice and it took a while to
freeze just that much soda that was
about half of one of these bottles and
in the end it still wasn’t nearly as
frozen as this is so grinding it up and
changing the surface area makes a huge
difference just got a little bit left in
this foam it’s just top this off there
we go that’s our orange and lime or
sorry Mandarin and lime flavored sodas
mixed together and there is still chunks
of dry ice in there you can see the
vapors that are still forming I dig down
I can pull a couple of them out take a
gamble here I don’t think there’s much
dry ice in this bit
Mandarin line that might have actually
had a little bit of fizz to it there you
go making slushies using soda and dry
ice we tried a few different varieties
and we learned a few things dry ice can
freeze soda into a slushy consistency if
you use a large chunks it may take a few
minutes of stirring what you’ll get
there you’ll get a nice mixed-up slushy
consistency unfortunately it doesn’t
seem to have much in the way of
carbonation in fact none of our
experiments really gave us a carbonated
slushy for the most part so something
about soda seems to not really absorb
the carbon dioxide once it’s gotten down
to the temperature where it’s cold
enough to actually begin to freeze we
tried taking your dry ice and blending
it up into a powder to see what
difference that made when we mix it into
our soda and it froze way faster it went
from five or six minutes of stirring to
about 10 seconds of stirring it was
already frozen but we also still had
little chunks of dry ice sort of mixed
in with our frozen soda and we don’t
want to be putting the chunks of dry ice
in our mouth so you have to be really
careful sort of picking around the dry
ice as you scoop it out into your cup
then finally we tried freezing our dry
ice even more in liquid nitrogen to
really bring the temperature down
because that also makes it more fragile
so we took our super cool dry ice broke
that down into tiny little chunks and
powder and mix that in with the soda
that did an amazing job of freezing this
sort of very quickly as well
fact we’re able to freeze two entire
bottles full our soda and it still turn
into slush and had some dry ice left
over
so overall the dry ice definitely has
enough freezing power to make a slushy
out of a bottle of soda but it can take
a while if you want to do it the safe
method which is to leave some larger
chunks that can easily be picked out
once your slushy has formed thanks for
