Can You Take the WATER Out of Watermelon?

in today’s video we’re gonna try freeze
drying water by far the most requested
things watermelon water and dry ice
guys we’ve had a few videos in the past
using our harvest right freeze dryer
that’s a very interesting machine it
cools stuff down pulls a vacuum and then
warms it up just a little bit as it
warms up all of the frozen water inside
the food sublimates turns into a vapor
and gets pulled out it extracts all of
the water from the food without it
ending up soggy
or mushy or anything like that and in
those videos we have had so many
requests for things to freeze dry and by
far the most common three have been
watermelon dry ice and water you want to
see what’s left when we extract all of
the water out of water well we’re gonna
try it this is just about one week’s
worth of asking for water dry ice or
watermelon if I didn’t miss any there’s
a lot here’s the basic idea we’re gonna
make some dry ice some sliced watermelon
and some water in a few different ways
we’re going to put them in our freeze
dryer and we’re gonna see what’s left
after we let it run well I don’t know
exactly what’s gonna happen if we freeze
dry these things and so we’re gonna try
it we’ve got ourselves a watermelon
we’ve got some dry ice and then of
course we have water and we’re not just
gonna put a cup of water in we’re
actually gonna do a few different
varieties of all of these now for the
watermelon this is supposed to work best
sliced into thin slices and then frozen
before we put it into the freezer so
that’s what we’re gonna do with the
watermelon with the water we’re gonna
have a few varieties of pre frozen and
not pre frozen we’re going to have tap
water we’re going to use salt water and
then we’re also going to use distilled
water that should be water that has all
of the impurities taken out so it’s just
hydrogen and oxygen combined with
nothing else in there along with the
three types of water we’re also going to
try some juice ingredients are water
cane sugar and juices so we’re gonna try
a little bit of this as well and see
what we get dry ice is dry ice and I
don’t think it’s gonna change a whole
lot no matter what we do with it so
we’re gonna take a piece of that we’re
gonna put that in as well I should also
say that we’re gonna do something a
little bit different with the freeze
dryer and that’s that we’re gonna take
our dry ice we’re gonna put it in but
we’re gonna modify how the pump runs
because the dry ice is going to expand a
lot before the freeze dryer kicks in
with it’s vacuuming and we don’t want to
build up pressure in
side the freeze-dried so we’re gonna
have it set up with the vacuum running
the entire time I’ve been assured by the
wonderful people at harvest right that
that is going to work and should not
mess anything up but it may be a little
bit interesting with some of the other
liquids that are going to be in the
machine at the same time all right let’s
take our dry ice our lemonade both
frozen and frozen are three varieties of
water frozen and unfrozen and then our
frozen fruit mostly we’ve got watermelon
there’s also just a little bit of
cantaloupe in there too to see how that
guys the spy scope kits are out in
available mail they come with everything
you need to build your cell phone spy
scope works as a microscope so you get
all the parts in this way you don’t have
to go to like several different stores
trying to find everything so you don’t
end up with anything extra however you
do get some really fun slides you can
make your own slides and you can also
get some of these bonus slides that have
hidden codes on them once you find all
the letters you can unscramble them to
reveal the secret code and that will
unlock something very special
guys these are awesome click the link in
the description below to get yours now
guys it’s been about 24 hours our ice
our Juice our melon and our driest have
all been in the freeze dryer this whole
time let’s see what’s happened to them
well looking in so a few observations
before I even open this so this is still
vacuum sealed right now it’s under
fairly low pressure there were a couple
pieces of dry ice I had right here in
between this mold and the slices of
watermelon so just right there on the
paper towel they were two chunks of dry
ice about the size of a deck of cards
and those are just gone and I did watch
a little bit as this was going and those
just dissipated away into nothing which
is what we’d expect it’s dry ice it
sublimates away and even though this did
get pretty cold it’s not down to the
temperature that prevents dry ice from
sublimating and then the lower pressure
probably just helps play that away as
well I can also see that our six trays
that had the raspberry lemonade in them
those heart shapes go still appear to be
full of substance and then looking back
beyond that I can see where we had our
distilled water our tap water or salt
water those three trays seemed to be
showing something pretty interesting
different levels of the content so let’s
and it’s interesting looking watermelon
let’s take a look at the watermelon
first so I should explain that I didn’t
actually put the watermelon in in the
best way because we didn’t have this in
contact with the heating element laying
flat it didn’t all sublimate out at the
same rate it pulled a little bit out of
the rind and the sides where it was
leaning up against the heating pads in
the side of her box that heated up as
well but we do still have this little
frozen section down at the bottom if we
done it all correctly it’d probably be
more like this top part but let’s see
what this does
so Waterman of course normally is very
squishy spine it’s like a soaking wet
sponge and now this just snapped right
off like a dry styrofoam material see
how light and porous that is I’m just
gonna squish it I bet this just powder
eyes right here go on
Wow that’s actually a very concentrated
watermelon flavor I was kind of
wondering to it end up being a little
bit weak or something but it’s not it
really tastes very strongly of
watermelon I’m going to get a cup of
water and dip this piece of watermelon
into it see the dose
the texture has changed a little bit the
outside is like a little bit slippery
earth been a normal watermelon slice
would be but it’s still very
identifiable you’d be like oh it’s kind
of a baby piece of water moments been
sitting out for an hour but that piece
had not been in there long enough to
fully reconstitute and so it’s like
watermelon the outside with a little
crunchy layer in between the interesting
snack I like that we’ve got some pieces
of cantaloupe here you can hear how
lightweight and rigid that is which is
really good I want to say not usually a
very good fan of cantaloupe I like that
quite a bit really really light and
fluffy good crunch to it lunch
it’s lovely pretty good all right same
thing you take one of these pieces
cantaloupe throw it in the water
I was not a fan of that texture it
seemed a little bit extra hard on the
outside which is kind of interesting
because just the freeze-dried versions
super soft and powdery this is our
raspberry lemonade here and these are
our three types of water so if got
things labeled with the little March
those are the ones that were already
frozen and then these three are the ones
that were not frozen this was just this
went in as juice over here on this side
this is the liquid side and this is the
frozen side marked with a melon M this
was the salt then the tap water and then
the distilled water so the one that was
well mostly frozen the salt water did
not freeze 100% what this is like baking
soda consistency it’s super super light
and puffy like this is not grains of
crystallized salt this is just powder
that seriously just looks like powdered
yeah that’s remarkably salty something
else that’s really interesting is this
it’s basically evenly distributed that’s
about as high as I poured the water but
it hasn’t really dropped down at all
it’s just got suspended at the same
height that it was poured in so this one
was liquid then I can see some bubbles
in it which I assume means that some
bubbles started to form as it was
freezing because it was under low
pressure we did have the vacuum pump
running for a lot of the time and as
soon as that dry ice sublimated away it
seems to drop in pressure quite quickly
got to be some really cool use for salt
that’s in that powder to reform I’m not
sure what it is yet but I’m gonna be
thinking about that okay let’s take a
look at our tap water now unfortunately
I think that as our salt water was
bubbling I do think it launched some
salt we can see we’ve got little bits of
salt all over the edges and in between
and stuff like that and that wasn’t
there originally but we can see what I
think is actually just the residue from
the tap water this is all the minerals
that comes out from the tap water right
there I am going to see if I can taste
those minerals I don’t know if it’ll
stick to my glove I’ll try it just with
my glove dry if that doesn’t work I’ll
try like licking my finger a little bit
first and see if I can get any on there
maybe a very slight earthy taste I don’t
know about as much taste as tap water
has I suppose which makes sense since
it’s from tap water that’s everything in
tap water that isn’t water and then our
distilled water well it’s got some
flakes in there that I’m fairly certain
our salt that got thrown by the other
ones but for the most part I think that
just dissipated into nothingness I’m
gonna do a little test and gather up
some of these plates here and see if it
always just tastes salty yeah
that’s just salt so the distilled water
completely disappeared okay here we go
so these these were raspberry lemonade
this is a raspberry lemonade that does
not have any high fructose corn syrup in
it so these three were frozen these
three were not and if we can actually
pop this out of the silicone that is
fragile this actually looks like it
could be delicious this should be like a
concentrated raspberry lemonade flavor
oh my gosh whoa
that is a concentrated raspberry lemon
flavor with about the consistency of
very lightweight styrofoam and cotton
candy I would buy that if you could buy
that I would buy that so guys if you own
a super fancy high-end restaurant and
they have fancy desserts
I recommend freeze drying some raspberry
lemonade don’t freeze it first and you
sprinkle out on top everyone think it’s
delicious has no idea how you did it I
want to see if we can reconstitute this
I’m gonna pour a little bit of water
into one of these about how much water
will there was before mix it up and see
if it turns back into lemonade
it looks pretty well mixed together
spoonful of it out that looks like about
yeah that’s really good it’s a good
raspberry lemonade and it’s literally
just the exact same ingredient we just
took the water out and then added water
back in so it should be possible to make
a really good lemonade powder by
freeze-drying say a whole bottle of this
stuff and then you just take the powder
and pack it down and it would be real
juice it wouldn’t just be like a
simulated like oh it tastes kind of no
it’d be an actual juice it would be from
concentrate because boy are you
concentrating it so you could definitely
make your own if you wanted to go hiking
off in the mountains somewhere and have
some like really good made with actual
juice powder it’s not just like a
kool-aid type thing it’s delicious water
it pretty much disappears
salt water makes a really cool salt
powder freeze-drying juice made with
cane sugar and at least with the
raspberry lemonade it works great I want
to try that with some other kind I’m
curious what kinds of juice you can turn
into a DIY juice concentrate powder guys
