In today's video,
we are seeing if it's possible to carve eggshells using
the acid found in vinegar.
[Music]
Guys, in the previous video,
you saw me dissolve an eggshell to make
a rubber egg using the acetic acid found in vinegar.
So today, I want to put that to the test.
You've probably seen those really cool eggs
that people carve,
and make really really pretty designs.
Well, they're beautiful, but they take a lot of time.
I want to see if we can make a cheap method today.
Here's the basic idea.
We have three different substances that should make
egg shells impervious to the acid found in vinegar.
Let's see if we can carve
patterns on these shells using these substances.
Now, here's where this idea came from.
I'm not sure
if you've ever seen that really easy kids science project
where you use,
basically, a darkly colored soda and fluoride toothpaste.
Now, what you do is
you coat one side of an egg with fluoride toothpaste,
and you drop it into a cup full of soda.
What happens is the egg shell itself will actually start
to become a muddled brown or a dark sort of color
where the toothpaste isn't.
The basic idea there is that it's showing you just
how fluoride protects the enamel on your teeth,
and what soda can do to your teeth as well.
So, I want to go ahead and see if using toothpaste,
we can basically put a design on to an egg shell,
drop it into some vinegar,
and see if it'll actually protect it
from the acetic acid found in it.
There's two other things I want to try as well,
both a clear nail polish and a clear acrylic varnish.
Now, the reason why is because I want to see
if just putting a coating on the outside of the shell
is going to protect it from the vinegar.
I'm not sure if it will, but I wanna find out.
All right, so we've got our supplies.
We've got our eggs.
Let's go ahead and get started.
So for our first test,
I'm going to go ahead and try our fluoride toothpaste.
Now, I don't really think, even using a squeezy tube,
that's going to come out very pretty.
So we're going to go ahead and use a dosing syringe to get
that toothpaste into a design on our egg shell.
That should work.
All right, let's see if we can make this happen.
Now, normally, when you carve an egg,
you want it to go all the way around.
I'm not going to worry about that today
because I want to be able to set this down to see
if we can dry just a little.
So, we'll just do one side of each.
So, anywhere that our toothpaste,
or our paint,
or our nail polish is going to be,
that's where, hopefully, the eggshell will not dissolve.
All right.
Next up, clear nail polish.
Quick drying.
So, for our nail polish,
and our acrylic varnish or polyurethane varnish,
I'm going to go ahead
and make our designs a little more intricate
because I'm crossing my fingers
at these might work just a little bit better,
simply because I'm not sure our toothpaste is going to dry.
So we're going to go ahead and leave this one for now.
Start on our acrylic,
and once this is dry, we'll go ahead and do the other side.
[Music]
All right.
One side on the acrylic egg done.
So now that our nail polish egg is dry,
I'm going to go and flip it over, work on that
while this one dries.
[Music]
So, it is much harder to see the acrylic paint on this egg,
but that's the point.
By the time everything dries,
and if this works, I want it to look
like just a regular egg.
So I'm liking the fact that it's so hard to see.
All right.
So while those dry,
I actually have one other idea for our eggs.
Now, right here, I've got an egg
that I hollowed out earlier.
You can see that I've put little pin holes through it,
and then blown out all of the guts.
The reason why is because my hope is
that without the inside,
it may actually allow the vinegar to seep into it too,
might make it a little bit easier
for the eggshell to dissolve wherever I don't have
anything covering it.
Let's see what we can do.
[Music]
While that dries again, let's go to the next one.
[Music]
I have the nicest handwriting, guys.
Plain egg, and just within a couple of seconds,
you can start to see the carbon dioxide bubbles forming
on the surface of that shell.
Our toothpaste egg,
which is just a messy nightmare.
Let's be honest here.
Nail polish.
Our regular acrylic paint.
And our hollow egg,
which is only just occurring to me
that I think it's gonna float.
So, most of this egg is already covered in acrylic paint.
So I'm just going to make sure that the part with TKOR is faced down.
Fingers crossed that works.
Oh, yeah,
that's just going to sit like that.
Now, this is a good sign already.
You can see on the nail polish egg
and the acrylic paint egg,
that is solid not hollow,
you can see that where I've got the acrylic paint
and the nail polish,
the bubbles are forming around those places.
That's a good sign.
We don't necessarily need to cover these up,
but it smells a lot like vinegar in here.
So I'm going to go ahead and cover the tops with saran wrap.
We'll leave him for 24 hours.
See what happens.
[Music]
All right, guys, so I'm going to be honest with you.
I left these eggs over the weekend,
and most of them died.
By died, I mean that they completely dissolved.
Some of them were just total messes,
and there wasn't anything left.
So, we started a new batch.
These ones have been in here about 24 hours.
There were two that I left
because I thought they were pretty interesting.
The toothpaste egg
and our hollow acrylic egg did things I wasn't expecting.
So let's go and take a look at all of these,
and just kind of show you how these turned out.
You've seen us make a rubber egg before by dissolving off
the shell using acetic acid found in vinegar before.
So, this is just one of those eggs,
and how it's done.
Shell itself is slime, basically.
What you're left with is just
a rubber bouncy egg that you wouldn't want to bounce,
because it's rotten.
That'd be disgusting.
We have one very,
very squishy egg with almost all of its shell dissolved.
You can see where it kind of raised up to the surface.
This part wasn't fully submerged into vinegar.
But even that would come off if I just rubbed it enough.
All right, so our toothpaste egg.
I think there's still an egg in there.
This actually just ate all the way through.
Now, it had started to crack and spider webbed,
and now, the shell is,
it's still there much more than the other egg shell,
but it's still goofy, and it could still come off.
So, is toothpaste going to save an eggshell from acetic acid?
No, it's not.
You can just see the difference.
So we're going to go ahead and wait on our two painted eggs.
I think these two actually probably has some good results.
So fingers crossed.
I want to take a look at our hollow egg real quick
because this one also looked like it was going to work,
like the toothpaste one.
Now, the toothpaste one was fascinating
because it held out longer than the normal plain egg did.
With our hollow egg,
it survived but in a fascinating way.
I don't even think I can take this out of the vinegar
because all that's left right now is the bubble skin.
There's nothing it's protecting on the inside.
So, while there are some places that you can see
that the acrylic paint sort of saved the shell,
I think it actually got inside, ate up and around in it,
and so now, it's just, well, it's that.
Yeah, there's vinegar,
and this is what makes me think
that the shelf fully got eaten through is
because you can actually see that there's liquid inside.
This was a fully hollow egg.
It just soaked up the vinegar.
The vinegar somehow managed
to get in the egg through those little tiny pinholes.
I don't even know where,
but the shell itself is just flaking into pieces
in my hand now.
So, that's really gross.
So first, we'll go ahead and take a look at our egg
that was painted with nail polish.
Now, already,
I'm kind of excited because you can actually see
that the shell is still there,
intact in some places where I painted it on.
So my hope is that any place where you can still
see white stripes where the paint was,
I'm hoping that that is still solid shell,
so that when we pop it,
and we try and drain out the egg itself,
that will stay in place.
[Music]
Aha!
So far, so good.
This is hilarious.
The egg,
because the egg was starting to rot, it's expanded.
So if you get a top down view, you can actually see
that the egg itself is expanding from where the shell was,
which means this is going to smell really great
when I break it open.
Gross.
Gross, gross.
[Music]
Oh my gosh.
It worked.
There you go.
Laser light show egg.
We'll see if we can carve out that lining.
See if we could just get that shell like we want.
Yes, in case you're wondering,
the entire studio smells like rotten egg and vinegar.
A carved egg using nail polish and acid.
Let's take a look at our polyurethane paint egg.
Hopefully, it'll pour out just as easy.
I'm a little bit more concerned.
If you take a look at this one, you'll notice
that it doesn't look like the acetic acid is eaten
through as much of the shell.
Also, there seems to be some cracks up
at the top on one side.
I'm just very glad
that Nate isn't in the studio today.
He's not trying to eat anything right now.
This one did not survive nearly as well as the nail polish egg.
You can actually see the cracks running through the shell.
It still feels pretty stable.
I still want to try though.
It did eat through the sides.
I don't know if it's going to work as well,
but let's find out.
Okay.
Well, so far so good.
Similar results.
You can definitely see
that some of these sides did not hold up as well.
But they're still there.
Already lost that one side right there.
So I'm not even going to finish trying.
I am going to try and peel out that lining
because the nail polish egg
did survive me pulling out the lining.
This one, just me trying to slice through isn't working.
If I pull it out,
I have a feeling this whole thing's going to crumble.
But let's see.
[Music]
As I'm working,
the whole egg is just crumbling.
So I think that's as good as we're gonna get with regular,
just clear acrylic paint.
However, compared to our fully hollow egg,
we're still doing better.
So, comparison time.
We've got our fresh regular egg,
we've got our control test plain egg,
and egg with toothpaste,
and the egg with acrylic paint,
a hollow acrylic paint egg, and then, shockingly to me,
the nail polish egg.
That's the one that survived, and now, obviously,
I was just going for a very quick and easy design.
Something that I thought would structurally hold up,
which it obviously did.
But if you wanted to spend some time,
even with another sort of clear nail polish,
and really put in some detail,
you can carve an egg without having to do much work.
All I got to do is paint it, put it in some vinegar overnight.
