hey guys welcome back thanks for joining
us today on the king of random we’ve
often done some chemistry experiments
that are hard to do at home because it’s
hard to get your hands on the right
chemicals or it’s a little too dangerous
well today we’ve got some experiments
that are easy and safe to do at home
with chemicals that are very readily
available all of the experiments we’ll
do today will involve milk as a main
ingredient the first experiment we’re
gonna try involves milk and a bottle of
Cola all the milk is almost pH neutral
some of the components in it react
interestingly with the acids and bases
found in other chemicals we’re gonna try
pouring some milk into one of these Cola
bottles and watch what happens as it
reacts with the acid in the soda alright
we want to let a little bit of the gas
escape otherwise it’s gonna overflow and
spill over also probably just pour out a
little bit of the soda before we add our
milk just to make more space and I have
also shaken it up and slowly opened it
to try and take out some of the extra
bubbles now I’ll pour in the milk and
we’ll let it sit for a while to watch
what happens it’s gonna react and
hopefully not overflow that’s one of the
main reasons I tried to get rid of some
of the extra bubbles cuz if I’d done
that when it was new it probably would
have just exploded everywhere wow that
can be cool it’s not what we’re going
for today oh this is dangerous because
if I don’t hold it tight enough it’s
just gonna explode everywhere I think
it’s going to explode everywhere
oh all right almost unscathed
just got a little bit in there and mix
this up a little bit you can already see
what’s starting to happen there’s little
flecks and bits visible floating around
in the soda so now we’re just gonna take
this and we’re gonna let it sit for
about 45 minutes and watch what happens
to it all right our bottle of coke and
milk has now been sitting for a little
over an hour and you can see how much
it’s weirdly separated out to be honest
I’m not sure what exactly the different
components here are we’ve got some sort
of bubbly foam up at the top and we’ve
got this darker brown disgusting
whatever it is down at the bottom and a
clear liquid I mean it’s clear it’s
murky looks kind of like swamp water but
you can see through it that’s for sure
alright let’s open it up see what we’ve
got inside well that’s pretty
interesting all the bubbles escaping our
lifting some of the mix with it it still
smells like Cola that looks really gross
but I am gonna try a little bit of this
should just be Cola and milk but okay
weirdly enough that actually just still
tastes like Cola right this clear gross
liquid it tastes like Cola still weird
now we’re gonna do an experiment that I
learned way back in elementary school
and I’ve always thought it looks really
cool it involves using milk food
coloring and a little bit of dish soap
the setup is very simple
find a nice shallow pan or plate and
fill it with about half an inch of milk
after you filled your container with a
shallow layer of milk take your pick of
food coloring and drop a few drops
around your milk now I have my container
of dish soap and you can either drip it
in just with single drops or if you have
a long bamboo skewer or something
similar
you can touch that into the soap and
then touch it into the milk near the
food coloring
boom
the soap starts reacting with the milk
and makes it spread out in these weird
smoke like patterns and when it runs
into the food coloring it spreads that
out in its own smoke like patterns that
run across the surface of the milk it’s
a really cool swirling patterns doing
this alright it’s already kind of
swirled up but I am gonna try just
dripping in a drop of soap and see if
that does anything at this point yes it
does look at that it just flies away
that’s pretty fun let’s try a couple
different colors and do this again so
what’s happening here the soap lands on
the milk but it doesn’t mix into it it
starts dissolving over the surface of
the milk and as it dissolves it spreads
out into incredibly thin layers the food
coloring is less dense than the milk and
so it tends to sit on the surface of it
so as the soap is moving around
spreading out it pulls and pushes the
food coloring along with it the soap
begins to bind to the fat in the milk
which is what makes it keep moving and
swirling around even after it’s been in
the milk for a while our next experiment
is somewhat inspired by those videos
you’ve probably seen of making elephant
toothpaste that’s a combination of
chemicals that sort of combines quickly
and explodes out in this really thick
dense foam what we’ll do isn’t quite as
explosive or rigid but it is
impressively similar how thick and fast
it foams up the first step is to just
pour about half cup of milk in each
plastic cup now we have here some baking
soda and some citric acid one is a
fairly strong base and the other as its
name implies is an acid if you want to
buy citric acid it’s usually sold with
canning supplies in your grocery store
this is a powdered crystalline acid this
is the same stuff that makes lemons and
limes sour you may have experienced some
point your life candy that’s coated with
this stuff it’s just a white powder but
it’s extremely tart
mmm yep if you ever had warheads this is
what’s on the outside of them I’m going
to add one tablespoon of baking soda – 1
cup and 1 tablespoon of citric acid to
the other citric acid into the milk stir
up both of those and you can see that
I’m doing this on a cookie sheet because
when I add one of these milks to the
other one it’s just gonna immediately
turn into a foam that sprays up out of
the cup so here goes boom it erupts all
over and it’s like a really thick foam –
it holds its shape pretty well doesn’t
just collapse do that there you go nice
thick milk foam I’m gonna taste it mmm
yeah that’s gross it’s like a little bit
sour because of the citric acid but it
also has like the baking soda taste
which is sort of oh I know salty but if
something can taste powdery then baking
soda tastes powdery I want to try that
again but I’m gonna add food coloring to
the milk before I combine them and see
if we can get like a colored elephant
toothpaste coming out of their home for
a bright green sort of booze so I’m
gonna add some green to one side it’s
some yellow to the other baking soda in
one citric acid in the other those
together
and colored milk foam eruption right and
milk volcano in three two one
hopefully ah there you go that’s a way
better volcano than baking soda and
vinegar yeah it slowly oozed off
everything got like this nice red color
down here milk lava and now for one
final experiment we’ll show you how to
take milk and vinegar and turn them into
a form of plastic the first step is we
want to take about one cup of milk and
heat it up on the stove you want to heat
the milk up to a point where it’s just
barely too hot to touch don’t let it
boil once your milk is hot remove it
from the heat and add four teaspoons of
white vinegar you should be able to see
the vinegar reacting with the milk
pretty much immediately as you stir the
vinegar it will very quickly start
clumping into a disgusting mess you can
see it separating out into clear liquid
and some white stringy stuff once it’s
mixed in and really separated pour your
whole mixture through a strainer this
will separate out the clear liquid and
the white goop what you should be left
with is a soft white substance that kind
of looks like you squished up a
marshmallow you can rinse this off with
cool water to make it easier to handle
now this white mush is mostly made up of
what’s called milk casein one of the
components in your milk I’m just gonna
squish it between a couple of paper
towels to try and help and dry it off a
little more
there you have it now this substance
which right now is behaving sort of like
a slightly crumbly clay will eventually
dry to become a fairly hard plastic it’s
also interesting when I first mixed this
up I thought that it would smell
terrible because it’s basically made of
vinegar and curdled milk but it really
doesn’t have much smell at all I’m also
gonna taste it even though I think it
might be gross
hmm kind of a gross texture like if you
chewed up string cheese and then spat it
out it’s about like that texture but it
really doesn’t taste like anything it
doesn’t taste like milk it definitely
doesn’t taste like vinegar it’s just
kind of there and try and form this into
a triangle like the king of random
symbol to be honest I worked as a
sculptor for a few years this is not the
nicest F to sculpt with but it is pretty
neat that it’s just made of milk and
vinegar I’m just gonna take this
triangle I’m gonna put it up on the
Stealth shelf for a few days and we’re
just gonna see what happens to it
we’ve now let our vinegar and milk
composite sit for several weeks and
really let it dry out and holy cow this
thing is just hard plastic at this point
you see if I can use pliers and break it
yep with pliers I can break it there we
go
interesting it does have a little bit of
variance of texture running through it
looks like there’s sort of an outside
and then an inner core probably just
where it dried faster and slower just
see if you can sand it with sandpaper
and sand it quite well with the
sandpaper in fact it’s surprisingly
smooth there’s the rough side and then
here’s the side that we’ve sanded down
all right I was so curious about what I
could do with this that I just grabbed
the sandpaper and I carved it down into
something of an arrowhead shape it’s not
really sharp it’s it’s angled but you’d
never be worried about cutting yourself
with something like this it holds its
shape I suppose if that were on a stick
and it were traveling fast enough it
could stab through something it is
fairly lightweight so I’m not sure how
much weight it would be offering to your
arrow to really guide it but you know it
does shape pretty well surprisingly well
actually there you have it a few simple
chemistry experiments that you can do at
home that use milk as the primary
ingredient we mix milk with some Cola in
a soda bottle and watched it separated
into this murky clear liquid and then
this brown muddy looking sludge down at
the bottom some food coloring and dish
soap dripped onto the surface of the
milk gives us some amazing swirling
patterns as the
dissolves onto the surface of the milk
and pushes the food color and all around
it when we mix citric acid and baking
soda in cups of milk and then combine
the two we get a quick rising thick
dense milk foam which sort of erupts out
looks a lot like elephant toothpaste
that effect is even cooler when you add
some food coloring to it might be a good
experiment if you ever need to make
yourself a science fair volcano when we
combine warm milk with white vinegar
some of the components of the milk
separate and we’re able to strain out
the milk casein which is sort of like a
gummy clay that we can form into
different shapes and then it dries out
into a hard plastic if you’ve got any
ideas of things you want to see us try
with the milk and vinegar plastic let us
know maybe we’ll try it out thanks guys
for joining us for these experiments
today and we’ll see you in the next one
talk to you then you’re not gonna put in
a vacuum chamber nothing will happen
it’s solid plastic this is why you’re
not supposed to blow bubbles in your
milk this is where your parents were
afraid of kind of reminds me of
intestines you got like this hey guys if
