Ninja Stress Balls made with SLIME - YouTube

[Captions by Jeffrey D. at Y Translator] Hey guys in today's video,

we're trying out an idea suggested to us by Todd Crowell.

Who wants to know if we can make a ninja ball full of ooze?

[Intro music plays]

Here's the basic plan.

We already know how to make a ninja ball using flour as filling,

but we're gonna try and mixing up a batch of ooze,

and seeing if we can fill the balloons with that instead.

Will we get the same type of ninja ball?

Will it have the same squishing properties?

Or will we find something else?

First off, let's run through a refresher course

on how to make the standard flour-filled ninja balls.

We've got a bottle with a fairly wide neck at the top,

and then a regular water bottle that I've cut in half.

Let's use measuring cup and add ¾ of a cup of flour

into our bottle.

Now by tapping our funnel bottle, all of the flour will drain down

into the wide necked bottle.

With our 3/4 of a cup of flour in our wide neck bottle,

we now need to blow up a balloon just a little bit.

It doesn't need to be very full.

[Music]

That'll work.

Once we've blown it up. We want to twist it -- about four times

to really make sure that the neck is pinched off,

and no air can escape.

After twisting we want to stretch the neck

of the balloon over the neck of the bottle at which point we can let it untwist.

So, it's just got equal pressure inside the balloon and the bottle.

Once we're at that step, we can hold the neck in place,

flip the bottle upside down and start squeezing the flour down

into the balloon.

Let's pinch off the neck of the balloon

and remove it from the bottle,

and then slowly begin to let out the extra air.

At this point all the flours’ light and fluffy

and full of air.

So, if we're not careful, some of that flour could just start shooting up

out of the neck of the balloon like this:

We don't really want that to happen.

We want our flour to stay in the balloon.

So once all the extra air is gone, pinch the balloon off

and then start squeezing the flour around inside the balloon.

This will help remove any excess air,

and we can then let that escape out of the top.

Once we have all the extra air squeezed out of our balloon,

we need to cut the neck off.

We'll probably have a little bit of flour spill when that happens,

but that's not a problem.

Now, see we've got our flour filling up our balloon.

We now need to seal that in there so it doesn't leak everywhere.

Let's grab another balloon of the same color

and cut the neck off of it as well.

We now need to take this second balloon,

stretch the neck of it open,

and wrap it all the way around the flour filled balloon.

The flour is now sealed inside and can't escape,

but just to give it a little bit of extra strength and durability,

let's take one more balloon and wrap that around as well.

We now have a nice squishy ball that does this kind of weird thing

where it almost holds it shape into what you squish it into.

These are great as stress balls or if you're learning to juggle,

they work well for that.

There's a final decorative element we can add:

which is why we call them ninja balls.

It's sort of a ninja mask

for the stress ball.

Let's take one more balloon of a different color,

cut the neck off, and then cut some more holes in it,

that will allow us to stretch it over and give us a cool mask effect.

One hole cut in the top, one in the bottom,

one on each side, and then we can fold it in half

and add a final cut.

We now have a balloon that's been sort of turned

into a rubber ninja mask.

We can stretch that over our ball,

and we've now given our little stress ball

something of a ninja mask.

[Music]

That, is how you make the regular ninja balls using flour.

And now, we want to see if we can do the same thing

but using slime rather than flour.

Will it give us a similar texture?

Will it still hold its shape when you squish them down?

What's gonna be the same and what is going to be different?

First let's mix up some ooze.

We've got one cup of water.

Now, we need to add 1/2 teaspoon of borax.

Next, we need half a cup of water and five ounces of clear glue.

Now this ooze is probably gonna end up

inside of a balloon.

So whether or not it has color might not make a difference,

but it's a lot more fun.

So we're going to add some color.

Also adding the color helps you see

when the glue and the water are mixed together.

So that's another plus.

That looks pretty well mixed.

So now we need to combine our two:

We've got our borax solution, and our glue solution.

These of course start mixing and forming our ooze very quickly.

Gets to a point where it really just makes more sense

to use your hands than a spoon.

[Music]

Now, we need to figure out a way to get this slime inside of a balloon,

and I think we're gonna try mostly the same techniques.

Although, I think we can probably cut out the water bottle funnel,

and just sort of force the slime down into the wide mouth bottle.

All right, I'm just gonna see if I can start pulling off pieces

of our slime and letting them turn into sort of long stringy bits

and fitting them down inside the bottle.

Whoo!

One big old bottle full of ooze.

That's pretty cool.

Now we need to try and squeeze that into a balloon.

Same method as before.

We'll blow it up, twist it off,

fit it over the neck of the bottle.

Now we just have to hope

that we can get our ooze out of the bottle, down into the balloon.

[Laughs]

Well it's in the neck of the balloon? There's a little bit of ooze

just sort of stuck there and it's sort of dangling down

into the main body of the balloon.

All right so my thought is that,

maybe we can fit more of the neck of the balloon over the bottle.

So, it's just going directly into the wide part of the balloon.

There we go.

You can see the neck of the bottle Is now entirely inside the balloon.

Hopefully, that'll let us squeeze our ooze more to where we want it.

Get in there, ooze!

[Baloon noise]

That's a fun noise.

Okay, that right there

looks like about the right amount.

I think we're gonna try this.

Pretty similar in size.

The ooz doesn't try and squeeze itself out the top like a flour does.

Ooop! Now it's trying to escape.

Stay in there, ooze!

I need to get another balloon on there before it all escapes.

I have to keep my finger on it until I get that of the balloon on.

Otherwise it just decides: "I'm leaving!" and erupts out.

I can tell you one thing for sure:

This is definitely more troublesome with ooze than it is with flour.

Flour isn't actively trying to escape all the time.

I think I got it, that was tricky!

And one more layer just for safety which should be a lot easier

since I no longer have to hold it in with one finger

while I'm trying to do everything else with the rest of my hands.

There we go, nice and contained.

Now let's just give it a ninja mask.

[Music]

Preliminary results.

We now have a ninja ball that is full of ooze.

It's blue ooze which might not make a difference inside the blue balloons,

and we can compare that to our ninja ball full of flour; which is standard.

Uhh... They feel about the same, they weigh about the same.

But even when I'm just lightly holding them,

I can feel that there's a difference.

The one made of flour feels solid

until you really squish it,

at which point it has an interesting give,

and kind of holds its shape after you've squished it.

The ninja ball full of ooze has more give initially

and then when you squeeze it:

it bounces back into shape a lot more.

It doesn't stay flattened the way you can do with flour.

See that the flower ninja ball really flattens out,

and the ooze ninja ball just kind of bounces back.

Speaking of bouncing, that's another pretty clear difference.

The ooze ball bounces, whereas the flour ball

just sort of stops dead.

Maybe has a tiny little bounce. The ooze ball is just-- it's bouncy.

I'm gonna make another one.

Like a good size.

Yeah, a little bit smaller than last time. It's actually a little bit smaller

than our standard ones too, but I want to see what the difference is

between an over-packed ninja ball and the less packed ninja ball.

And this one is still trying to squish it out.

I was hoping that by having less, it would just stop trying to escape

but that's not the case. It's still trying to escape.

Get back in there.

Stay. In. There!

So I still have to use one finger

to hold it closed

while use the rest of my hands

to prepare the other balloon.

Here we go. Two different sizes of a ninja ball.

Full of the ooze and I'd say they react about the same,

they feel about the same squishiness.

They really have the more,

classic stress ball feel when you use the flour.

When you use the ooze you get -- it's still a good squishy ball.

There's certainly nothing bad about that for squishing stuff.

Still works for juggling.

I'm curious how much I can get it to bounce.

So, I'm gonna try and throw it really hard.

[Music]

Got about, six feet of bounce. Let's try the other one.

[Music]

Ooh, that deformed it a little bit.

We forced it out of some of its layers.

Squished so hard that some of the layers of the balloon

started pulling away in spots.

Or it might have actually just started ripping.

Oh I think it did.

Yeah, it started ripping that away.

I just want to step on it till it pops.

[Music]

Took quite a bit of effort. I thought it was going to be

a little more fragile than that but I basically had to jump on this

to get it pop open.

So, I think if you're just playing around with it unless you're on really rough

or scratchy or spiky surfaces,

they'll probably be pretty durable.
