garbage ever hey guys I’m Nate welcome
back to the workshop you may notice that
I’m sitting around in the dark today and
that’s because today we’re gonna be
doing some experiments with glow sticks
we’ve got a huge selection of different
glow sticks right here and we’re gonna
see what we can learn about them just by
playing around we’ll see what happens if
we open some up and really get a feel
for what these things are like what’s
the texture of the fluid like does it
have a smell does it have a taste what
happens if we combine lots of glow
sticks together can we pull out the
separate fluid chemicals inside the glow
sticks and then combine them when we’re
ready to have a large amount of glow
today is the day to learn all of these
things the first step will be cracking
open one of these plastic tubes and
seeing what’s going on inside when I
look at one of these tubes up close I
can see that there’s liquid coming up to
about here and just below that is what
appears to be a glass vial I’m gonna try
and cut the plastic off above the label
of the liquid so that when it cuts it
doesn’t just leak out everywhere all
right the top of that kind of came off
pretty easily there’s definitely some
liquid running out so may be kind of
hard to see but there’s now what looks
like maybe a teaspoon of clear liquid
down inside this bowl and I have a vial
which sounds like it’s made of glass and
I think it is because I’m pretty sure
these are activated by cracking the
glass vial inside the plastic tube
has a slightly sweet smell not like
sugary sweet but some sort of chemical
sweet interesting now we’ve got our vial
which i think is glass and i’m gonna see
if i can crack this the same way I’m
just gonna see if our pliers and take
the top off of this hopefully not shoot
glass bits everywhere I’m gonna cover
with my hand a little bit just so it
doesn’t shoot shards of glass throughout
the kitchen it sounded kind of like when
you pop a Christmas light bulb and this
is also full liquid so let’s see what
happens if we pour this liquid into that
fun kind of swirl patterns in there when
bowl is looking pretty good it’s almost
acting as a little bit of a fiberoptic
Bowl the edges of it look like they’re
glowing quite a bit so there is the
contents of a single glow stick it’s not
much like I said that looks like it’s
about one teaspoon of liquid maybe a
little bit more but not a lot
all right now I don’t know what kind of
liquid says is so I’m just gonna dip my
gloved hand into it it does feel pretty
oily this doesn’t feel like a water
substance on the hands it just feels
like oil it’s very slippery that was the
result of getting one glow sticks worth
of fluid I kind of wonder what would
happen if we got like 20 glow sticks
worth of fluid together we’ve got eight
cups here and I’m gonna divide it out
into the four different colors and the
two different liquids for each color
[Music]
there’s no visible blue dye in this it
looks clear I only know that it’s going
to be blue because the package says
there is one and I already cracked some
other ones open so it looks clear at
this point but when I hit it with a
black light it glows blue the yellow
glows yellow the green glows green also
interesting is the activating fluid down
at the bottom doesn’t seem to glow at
all
it looks purple on video but that’s just
because the blacklight looks purple it’s
not fluorescing the way that the vials
are a pink fluorescing in the blacklight
as well so all of the dyes and whatever
else is in that vial lights up under a
blacklight that’s pretty neat all of our
activator fluid is now harvested so we
need to crack open the glass vials and
pour that into some separate cups I’m
also going to clean off each glass vial
with a paper towel to get rid of the
excess oil on the outside because I
don’t want it to start glowing before I
start combining oh and something’s
already activating we’re getting some
blue showing up maybe I need to make
sure to clean off my pliers better so
this is the empty cup or all of my blue
dye glass vial fluid into here looks
like a pretty similar consistency this
also feels oily maybe even more oily
than the other fluid we now have our for
fluids drained into four cups with the
four cups of their respective activators
let’s hit this with a blacklight again
and see how it’s looking look pretty
good well it was in the sticks whoo look
at that I love that blue like there’s no
color until you hit it with the
blacklight and then it is vibrantly
brilliantly blue pink magenta red
whatever color you want to call that
it’s it’s bright we now have glow stick
fluid out of 20 glow sticks divided up
into its four different colors and I
think it’s time we start combining I
want to see what happens if we have five
glow sticks worth of fluid at once in a
cup and then once we’ve got all four I
think we’re gonna see what happens if we
have 20 glow sticks worth of fluid in a
cup it looks like there’s a little bit
more of the activator fluid than the
glow fluid just eyeballing it I would
say it’s 60% activator 40% die here go
it’s a nice bright glow let’s do the
other colors that’s a pretty great glow
I would say that the green one is
definitely brighter than the other three
but all three of them are putting off
some pretty good light let’s put this in
rainbow order for you slightly obsessive
people out there now I want to see what
happens if we mix them let’s see what
happens if we mix the magenta and the
yellow I wonder if we can get orange by
doing that there are orange glow sticks
and I have some of those but I want to
see if we can get orange just by mixing
the magenta and yellow all right let’s
try some pink magenta color and some
yellow hmm that is a really cool swirl
look right there
they haven’t mixed together on their own
there’s little bits of orange in there
but right there it just looks like
swirls of glowing fire or something ooh
that is mixing and now we have orange
glow fluid that’s actually interesting
though like it doesn’t look pure orange
somehow it has like a slight green tint
to it it’s thicker in some spots where
looks really orange but kind of right
behind the thick spot there’s a thin
spot and they have almost looks and
green oh man we’ve almost got the whole
rainbow here I think we have to see if
we can push that just a little farther
and get purple I’ll pour off a little
bit of blue add a little bit of magenta
see if we can get a violet oh yeah a
glow rainbow well that looks pretty
great and now I think we need to combine
them all together and see how they look
I don’t know what color that’s gonna be
normal if you mix all these colors
together you’re gonna get a murky brown
but I’m having a hard time imagining
what does glowing Brown look like let’s
curiously
all of the colors combined gave us just
orange
I really thought we would lose more of
that orange color I don’t know what I
thought it would turn into the blue
seemed like it was so vibrant compared
to the red and the yellow that I thought
it would overpower it but it hasn’t I
tilt it like this you can see where it’s
thin at the back that’s what I’m talking
about that looks green in real life it’s
not just a trick of a camera looking at
this I would say we probably have I
don’t know about half a cup maybe a
little less than half a cup of fluid
it’s glowing quite nicely very orange
which is interesting since we didn’t
start with any orange fluid this is
yellow or magenta or blue and our green
and those combined to make bright orange
wouldn’t have guessed that I think I
know where that smell what that smell
reminds me of if you’ve ever used a wasp
trap that has a liquid bait in it it
smells a lot like that liquid bait pod
still pretty oily think that’s
interesting on my black glove that just
looks green that’s the same stuff that
looks orange in the container but
smeared onto my fingers it looks green
well I have to try this
it says non-toxic on the packaging I’m
not gonna swallow it is it working ah I
can feel it tingling on like gum I’ve
heard the glowsticks will glow a much
brighter when they’re warm and much less
when they’re cold so I’ve got a set of
glow sticks and I’m gonna set them in
this cup of hot water and we’ll let them
heat up for a bit after that will
activate them and compare that to a set
of glow sticks that have been cooling
down in the freezer for several minutes
on this side we have our glow sticks
which have been sitting in the freezer
for about 45 minutes and this side we’ve
got glow sticks that have been sitting
in hot water for I don’t know 20 minutes
so let’s try cracking all eight and see
which glow the best first the cold ones
[Music]
really not a very intense glow yet pink
ones barely going at all all right now
for the warm ones Wow well I’m gonna say
that is confirmed heating it up
definitely makes it put off more light
here’s our cold ones which barely seem
like they’re glowing at all in every
case the warm one is glowing way more
than the cold one warmth definitely
makes a difference cold ones not as
bright although it’s also interesting
that I believe if it’s colder it will
last longer so it won’t put out as much
light all at once but over time it might
put out the same amount of light there’s
something floating on the top of this
water and I got this cup it was just one
of the cups that had some activator in
it which makes me think that maybe the
oily feel of the glowsticks isn’t just
in my head maybe it’s actually an oil of
some sort so let’s see what happens if
we try and mix a little bit of our glow
stick fluid with some water there’s a
little bit of water at the bottom of
that cup let’s pour in some glow stick
yeah they don’t mix you can see that our
glow fluid is underneath our layer of
water and interestingly once again it
looks green we go we can see the glow
fluid comes up to about here and then
the water is just sitting on top of it
so the two do not mix together soap is
an emulsifier that can often let polar
and nonpolar fluids bond so let’s add
some of that and see if we can get them
to mix mmm the soap is activating with
the Glo fluid itself Wow that’s getting
a lot brighter which i think is probably
a result of the very warm water that I
was using which lends some support to
the idea that heat will make these glow
more intensely compare that to our other
fluid here’s the the difference between
the two at the moment this is putting
off a lot more light after being mixed
with warm water and even with the soap
it’s still separating back out mostly
now that’s so point in and it
immediately started doing something
really cool I don’t
what it was but I have to try it again
so I’m gonna pour off a little bit more
of our glow fluid here I’m just gonna
drip some soap in without any of a warm
Elgar’s really cool kind of reminds me
of when we made patterns in milk with
food coloring by dripping in some liquid
soap okay so now it’s getting even
brighter but there’s no hot water in
this one so I think soap might
chemically activate this stuff either
that or it’s just the stirring motion
but I think it’s the soap now I want to
see just how bright we can get some of
this to go we know that heat makes them
brighter and it seems that adding soap
makes them brighter as well so let’s
take both of these fluids let them sit
in a bath of warm water for a few
minutes then combine them with a little
bit of soap and see if we can just get
like an ultra bright glowing lantern
look I think our two different fluid
halves are ready and probably fairly
warm after sitting in that so let’s take
those out let’s combine them together
and then add soap and see how bright
this thing gets this is five green glow
sticks worth of fluid oh that’s just the
warm fluids mixed together that is
already you know affects us the colour
that’ll kill Superman right there
alright let’s try adding a drop of soap
[Music]
yep that gets a lot right oh my gosh
that is insanely bright I don’t think
it’s gonna last very long but something
about the soap pulls all the chemical
reaction into one spot and it just boy
that is a lantern check this out scary
stories tonight
gosh that is nuts and it doesn’t last
for like it’s already getting dimmer for
sure but for just a couple of seconds
that is just exploding with brightness
we’ve got a ton more glow sticks so if
you’ve got some cool ideas what you want
to see us do with them let us know down
