I love this game!

You throw the ball into the air then catch it with a special pad

but the amazing thing is that, when you turn it upside down,

the ball doesn't fall off!

It's completely stuck to the pad!

BLEEPING

I hear a beep, I see a flash. I wonder what they're going to ask.

BEEPING

-BOTH:

-Hi, Nina!

-Hi, guys.

-We've got a question for you.

How do they make things stick together?

That's a great question. How do we make things stick together?

Sticking things together uses lots of clever engineering.

Come to my workshop, and we'll investigate.

-BOTH:

-See you soon, Nina, bye!

-Bye!

I'm going to need some help to answer this one

and I know just who to ask.

OK, Neurons, time to get to work!

-ALL:

-Neurons at the ready, Nina!

Today's question is, how do we make things stick together?

Which Neuron will be most useful in helping us find the answer?

-ALL:

-Me! Me! Me!

Will it be fabulous Felix?

I can help so very much, if you need the sense of touch.

Will it be beautiful Belle?

I send messages to brain from ear. If there's a sound, I'll help you hear!

Will it be lovely Luke?

For looking and seeing, day or night,

I'll help you with your sense of sight!

Will it be awesome Ollie?

If it's pongy or whiffy, but you can't tell,

my messages help your sense of smell.

Or will it be baby Bud?

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!

FUTURISTIC BEEPING

It's Felix!

CHEERING

-THEY CHANT:

-Go Felix! Go Felix! Go Felix! Go Felix! Go Felix!

Marvellous! A little touch can mean so much, Nina.

Today's question is, how do we make things stick together?

Stickiness is something we feel,

so Felix, our touch neuron, will help us.

I need to get the workshop ready before the engineers arrive.

James loves spaghetti Bolognese.

Ellie likes telling jokes.

When I kick my football, my shoe stays on.

My shoes don't fall off when I run.

So today, for one day only, James and Ellie become the Engineers!

-Hi, Ellie, hi, James!

-BOTH:

-Hi, Nina!

Welcome to my workshop.

Thank you for your great question -

how do we make things stick together?

To find out the answer, let's start by using our senses.

Woo, woo! A senses experiment! We're ready, Nina!

So we have here a very cool pair of trainers.

But what is making the flap stick down?

Sticky fabric.

That's right! This sticky fabric, and it's a great invention

that's used on lots of everyday things

like these, so let's have a look.

There you go, Ellie. Try opening and closing that.

James! Have a look at that!

Oh, I've got that at home!

Have you? Oh, they're great fun!

SCRUNCHING AND RIPPING

Ha-ha! Very good, guys.

So the sticky fabric is different to glue

because when you unstick glue it can't stick again.

But sticky fabric can be stuck...

Whoa!

..and unstuck, easily.

It's what engineers call "re-useable"

because you can use it over and over again. Woo hoo!

"Re-useable" - I like the sound of that word.

So let's investigate how this sticky fabric works.

So if you'd like to put your strips together,

that's really good, guys, and pull them apart.

RIPPING

Yay!

That's a fantastic ripping sound! Rrrrip!

Now, what do you notice about how they feel?

Smooth and soft.

-Prickly.

-Prickly!

Hmmm. One side feels rough, and the other is fluffy!

I think we need to have a closer look at this sticky fabric

using my Nina-cam, and you guys can watch

on my little screen here. What can you see there?

Plastic hooks.

Wow! It's like a sea of bendy little hooks!

That's right. The fabric is covered in lots of tiny plastic hooks.

Let me just put the fabric together again to see how it works.

You can see the plastic hooks on the rough side

are catching on to the fluffy fabric and holding it together.

And when I undo it...

RIPPING

Ha-ha! What did you notice when it ripped apart?

The hooks unstuck.

That's right! When we unstick the sticky fabric

the hooks bend back and unhook the fluffy part.

And that's what makes the ripping sound.

And that's why it sticks and unsticks easily.

That is way cool!

Engineers invented this sticky fabric by copying the idea

from this plant.

Oh! This is a bur plant and these are its seeds.

Now, hold your hands out nice and flat.

Ooh! How do they feel?

-Rough.

-A bit rough?

The bur seeds feel a little spiky.

Sometimes when we're walking in the countryside

bur seeds can stick to our clothes. Oh!

So let's have a closer look at these bur seeds.

Oh! The bur seed has lots and lots of little hooks

that can stick and unstick to things easily

but these are quite small.

What would happen if we wanted to stick something much bigger?

Come on, guys, we're moving on to bigger and better sticky things!

Hmmm! Where do you think we're going today?

Nina mentioned bigger and better sticky things.

Maybe it's a huge bakery with yummy, sticky buns and cakes!

It's not a bakery, but I feel it's going to be fun.

NINA LAUGHS

RIPPING AND SCRUNCHING

NINA COOS AND LAUGHS

Oh! I'm stuck!

Ho-ho-ho! Nina's stuck to the wall!

NINA LAUGHS

RIPPING

Oh, ha-ha! Can I stick to you, sis?

You stick with me anytime, little bro.

-Oh, that's great fun, isn't it?

-Yes!

-So, when we touch the wall,

the special suits that we're wearing make us stick to it.

Now, try seeing if you guys can stick to each other.

-Now, what's happening?

-We're not sticking together, Nina.

That's right, because hooks don't stick to hooks very well,

and fluffy doesn't stick to fluffy. For the sticky fabric to work,

the rough fabric with the hooks must stick to the fluffy fabric.

OK, guys, what I'd like you to do

is touch the wall with just one arm. Go!

And take it off.

OK, very good. Now, how easy was it to unstick your arm?

BOTH: Really easy, Nina!

OK, now I'd like you to throw your whole bodies onto the wall. Go!

And try and pull it off. Pull, pull!

Oh! Ha-ha! OK, OK!

-Now, was that easier or harder to pull yourselves away?

-Harder!

That's right, because there was more of you touching the wall,

so the bigger the sticky area, the better it will stick.

Larger surfaces mean more hooks can stick to the fluffy fabric,

so it holds both sides together better.

So, your question was, how do we make things stick together?

We've discovered that the bigger the sticky area,

the better something will stick.

Sticky fabric and glue are all good for sticking things,

but how do we know which one to use, and when?

So, let's investigate! Okey-coke, over here,

I have two pieces of wood stuck together using glue.

I let it dry.

Remember to be careful when you're using glue.

And here, I have two pieces of wood stuck together using sticky fabric.

Now, we're going to gradually add weights, to test their stickiness.

Which do you think will be stronger, the glue or the sticky fabric?

-The glue.

-Let's see what happens. James, why don't you go first?

Pick up one of the weights and we'll do it at the same time.

Pop it in, gently. That's it. Woop!

Anything happen? No. OK, your turn, Ellie.

Hee-hee!

CREAKING

It's making a noise!

Oh, I think we could go another one!

Another one, then, go! Oh, no!

THEY LAUGH

Oh, fantastic! You were right. The sticky fabric has come apart.

Engineers use different sticky things for different jobs.

Glue is for things we want to stay stuck together and sticky fabric

is for things that we need to stick and unstick, over and over again.

-So, which one would be best, guys? On a bag?

-Sticky fabric.

Yes, because we open and close a bag,

we want it to stick and unstick, over and over again.

It's reusable.

I can use that word again. It's REUSABLE! Ha-ha!

OK, Now, which would be best to stick a model boat together?

-Glue.

-You're absolutely right!

If we're building a model boat and want it to stick together

for ever, and not come apart, we would use glue.

# Nina and the Neurons! #

So, your question was, how do we make things stick together?

I think we've answered it. We discovered that engineers need

different types of sticky things for different jobs.

And, the bigger the sticky area, the better something will stick.

And engineers invented this clever fabric to be reusable, which means

that it can be stuck and unstuck, over and over again!

Hee-hee! So, I hope that's answered your question.

-BOTH:

-Thanks, Nina, bye!

-Bye!

Oh, I've had a brilliant day.

Especially hearing the r-r-ripping sound!

It's been a marvellous day! I enjoyed feeling the bur seeds.

I've had a fabby day!

The sticky wall was brilliant fun!

And remember, engineers help to build the world around us.

They make things work and use science to solve problems.

See you again, soon, bye!
