In today's video,
we're doing a few more experiments with the ink removed
from ballpoint pens.
[Music]
A while back, we took 1000 ballpoint pens,
and removed all of the ink from them,
and collected it.
And we still have probably 800 pens worth of that ink.
Maybe a little less, but we've got quite a bit.
This is just a pool of pen ink,
and since we did that, we asked what we could do with it,
and we had several responses.
So today we've got five common requests,
and we're going to try them out,
and see what happens with our pen ink.
I still think my idea was the best.
Your idea was to paint your nails with it.
I'm just painting my nails.
With what?
Pen ink.
She's thrilled.
I'm not going to paint my nails with pen ink,
but here's hoping that works out for you.
I guess it's a really cool metallic black coppery color.
It's beautiful.
Here's the basic idea.
We've got five suggestions
of things to try with ballpoint pen ink.
We're going to go through the one by one,
and see what the results are.
Let's go through our comments one at a time.
Our first comment comes from Charlene McClintock,
who asks us to do a test to see if pen ink is magnetic.
Calli has a very powerful magnet in her hands.
Let's show the power
of that magnet off a little bit for a second.
I'm pretty sure this magnet has a 100 pound pull strength,
which means if it's on a flat piece of metal
that is attracted to,
it takes a 100 pounds pulling it straight away from it.
Obviously, the way
to remove it without that much for us is to use leverage,
twist it at an angle, pull it off.
So very powerful magnet.
Let's see if it wants to do anything at all to our ink.
It's not sticking to my nails.
The nails...
No effect.
That is a very very thin layer of the ink.
That is true.
This is probably like less than a drop of ink guys.
This stuff has great coating power.
This however is about a cup of ink.
So let's see if we get any result.
I'm going to start by putting it on the side of the glass.
So it doesn't just stick to our magnet
if it's magnetic.
Anything?
Can you feel it pull it all?
Nope, I feel no pull.
I see no ripples in ink.
Without the glass,
in case the glass is what's causing the lack of magnetism.
Well, whatever is in this ink that's making it metallic,
it's apparently not magnetic.
It does look metallic,
and maybe they're actually is real metal in ink.
I don't know the full chemical composition of ink.
But not all metals are magnetic.
The three elemental metals
that are attracted to magnets are iron,
nickel, and cobalt, and some of their alloys.
Steel for example is an alloy of iron and carbon,
and sometimes other things,
that usually is attracted to magnets.
Thank you for your suggestion.
It would have been really cool if it were,
because that would've been
like a really cheap source of ferrofluid.
No magnetism here.
Alright, so for our next comment,
we have got one from mamasboy -99.
How would electricity work in the pen ink?
So you can see,
when I touch the two metal pieces together,
it's a very bright little light that we've got there.
Put something in the way of that,
like my tongue.
Lights up a tiny bit.
Not as much.
So there's something in the way.
Alright, so first as a comparison control test,
just regular water.
So here's how bright it is without anything.
And then in the water.
Very light glow.
Now, pure water
distilled water probably would give us no result.
But this is tap water,
it's got minerals in it, imperfections.
But now we're adding salt,
which hopefully will make it even better.
Well, that's quite a bit--
Yeah.
Okay.
Still not as bright as the wires touching however.
Let's try the ink.
And into the ink.
[Music]
There actually is a tiny tiny little purple.
Oh, you're very--
Are you sure it's not a reflection?
Yeah.
So you can see
that the wires are about two inches apart in ink,
and that's giving us an extremely low,
but not nothing glow on our LED.
It's much worse than salt water,
and it's actually worse than non saltwater.
So mamasboy -99,
we do have conductivity through the ink,
but so little that it barely counts.
Our next comment request comes from Icey Paw,
who says, try putting dry ice into pen ink.
I'm just going to dip it, and see what happens.
[Music]
That did not stick.
Sticking to the plier.
Yeah, the pliers are getting stuck to it.
But look at that, it's actually--
Oh, it's freezing ink in streams.
Here.
Try and-- Try and let's see if we can like capture--
Pliers it together.
Oh, that's weird.
So odd.
Because it's still a liquid, guys.
We're just freezing it.
The bottom, where it's actually in contact,
I think is...
Yes.
Started to freeze.
Oh no.
See it like that.
Sucked my glove immediately.
See if I can flip it over.
No, it's stuck in my hand.
Oh no.
This is weird,
because it's like partly frozen so it's like gummy.
This part starting to dull.
It's actually...
Oh, it is.
Look at that.
You're actually--
>> You frozen the ink. >> Frozen all the way through.
All right, I'm going to try and pull it off of that.
Oh my goodness.
Look at that.
It's just a chunk.
Okay, I'm gonna destroy my gloves,
but that's fun.
Clay is a really good description, but it's--
Except it's melting into sticky--
If you were to mix clay and slime, but it's...
It has this give of like a gummy candy almost, except it's--
It is warming up rapidly,
and quickly just destroying my gloves.
Yeah.
This elastic texture
is not something that I was expecting,
but my goodness, it's fun.
[Music]
I win.
Did you get it out?
I did.
Good.
Well, I think we should progress to mixing even more dry ice in.
That was the comment,
is try putting dry ice into the pen ink.
We've done everything, but that so...
So here it goes.
Yeah.
Dry ice.
[Music]
Yes.
That's kind of what I was hoping it would have do.
So I got some pretty good shots blowing bubbles
into the ink last time, but now,
as it seals up over the dry ice,
it just makes its own bubbles as the dry ice tries to expand.
So while Nate plays with that, we've got another common request.
I apologize if I butcher this name.
I believe it as Ha Seung Jung, mix it with soap,
and then blow ink bubbles.
It's so cold now from the dry ice,
that we still got this pulled taffy consistency.
Yeah, you can already see
that there's like this cool gold sheen happening.
Okay.
So if anybody ever wants to make their own homemade galaxies,
ink and dish soap.
We are going to try and blow ink bubbles,
but this may be a little too viscous.
This is just ink and soap,
so we've added a little bit of water to this one.
Let's see what we can do.
[Music]
Well.
That's a nice bubble.
It's pretty though.
So ink and soap together,
not really making bubbles, but this ink, soap,
and water is.
With that weird mixture that Nate's got,
it really just looks like he's blowing blood bubbles.
That's freaking cool.
Well now, I'm going to start popping bubbles,
because I don't want them to expand up out of the cup.
Here. Wait, hang on.
This was an awesome idea.
It didn't go quite the way we planned,
but it was still cool.
Our last request is from OLIVERS758,
who asks if we can dehydrate the pen ink.
We've got two things we're going to try.
One, we're gonna throw some ink in our Dehydro-tron,
little dehydrating machine we've used before,
and the other is the reason that this has been
on the counter the whole time, is this is our freeze-dryer.
And we're going to see what happens
if we freeze dry ink.
We don't know how this is going to go.
We don't know how far this is going to expand.
So we're just going
to do a small amount in a very large jar,
and hope it contains it.
You may remember,
when we first vacuumed some ink,
it bubble up a lot,
and the clear sides of the cup that it was in just turned
completely black immediately,
and then you couldn't really see what was happening
inside anymore.
There's a decent chance the same thing is going to happen here.
We've seen some liquids bubble up a lot.
Will ink do the same thing?
We're not sure.
We've seen how rigid it gets when it gets cold,
and the freeze dryer does get very cold.
It might be enough to stop it from moving at all.
We can see...
We can look at it after 24,
and see if we think it's doing well.
Side benefit, we're testing out what happens
if you put a GoPro in a freeze dryer.
It may not survive.
And I know the burning question you all had,
did my nail survive this experiment?
Yes. They did.
Our ink has been run through the freeze dryer
and the dehydrator for about a day and a half now.
Coming up on two days at this point actually,
and we think
that at least one of them is finished.
It's gonna be very cold.
First off...
See if our GoPro survived.
Sorry little GoPro.
I mean, the battery is almost certainly dead at this point.
It's very cold GoPro.
I just wonder if we can even turn it on again.
That would be a fun experiment.
We'll see if this lived.
Okay.
This is my new favorite thing ever.
[Music]
Wow.
So obviously, this part is all very very dry.
This is very cold to hold.
You can see if it's frosting up.
Still getting ink marks.
This might be the prettiest stained glass thing ever.
It's kind of going gummy.
Interesting.
Okay, around the edges.
It's still a little squishy.
That's some fairly warm water.
Not too hot.
We don't want to risk breaking the cup or anything like that.
This is from our internal GoPro,
which apparently did survive its trip through
the vacuum chamber-- Whoop!
And there goes the ink.
That's amazing.
It explodes.
Which is funny, because like it doesn't look
like there's any air bubbles in ink.
But it's just sitting there for a while,
but apparently, there's enough that degases in low pressure,
that it just creates all of those bubbles.
Like obviously, a ton of bubbles.
That was insane.
And you can see what it's done to our perfectly clear glass.
Wow.
At this point, the glass is warmed back up.
It's not frozen there.
This is the same powdery dry ice substance here.
However, down at the bottom...
Now that you've warmed it back up.
Yeah, it was frozen in there,
and we saw with the dry ice how it gets really thick
when it freezes.
But now, this is warmed back up.
Alright, so we've exhausted just about everything
that we can do with the freeze dried ink.
Now, we want to see
what happened to our dehydrated ink.
[Music]
Well, that's cool.
You can see all of the places
where the ink hasn't dried yet of my handprint.
What's in here?
Okay, seems fairly liquid.
This is our common request,
asking if we could dehydrate the ink.
It is very thoroughly become inundated with the ink.
That's now the rest of our ink.
Yes.
And the freeze-dried.
Yeah, this is the rest of our ink,
and everything was freeze-dried.
So you can still see like the viscosity here, but now,
if I do the same thing to what we put in the dehydrator...
It's a--
It's a little gumier.
It does look
like it's sticking a little bit more.
But that's about it.
It's still, it's still ink.
In our first video
where we took the ink out of a thousand pens,
there were dozens,
and possibly hundreds of comments saying
that instead of taking the ink out of the thousand pens,
we should have just bought the ink online,
and you can buy ink online.
But it's not this kind of ink.
Pen ink that you buy online is much much thinner.
It's designed for like a quill pen,
or a fountain pen that you dip into the ink,
or you refill a well,
and then you try and draw with that.
It's not the same thing.
This would not work in a fountain pen.
This stuff is as thick as corn syrup,
and this is not the consistency
that you normally have in a bottle of ink.
So while, it would have been easier to buy a bottle of ink,
it's just completely different.
We wouldn't have learned what's inside ballpoint pens.
We wouldn't really know anything about that ink,
because it's just too different.
Another thing to mention is that when it comes to India ink,
the reason people like it is the quality of the...
Honestly, the blackness of the color.
It's very very dark, and there's no shine to it.
Ballpoint pen ink is usually known for having the sort
of metallic quality.
You're not going to get that with India ink,
or true India ink.
Guys, that's it for today.
But you know, the fun doesn't end.
We've always got more for you to see.
That box up at the top will 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 next.
If you hit this bomb here in the middle,
