Hello, I'm Maddie. And today I'm

looking through all of these toys.

This one is my favourite.

It's a spinning top.

What's your favourite toy?

The other thing I like to play with

is this train set.

It's really fun. It's got tracks,

people and even houses.

But, first,

I need to put it together.

Ta-da! But no train set is

complete without a train.

And every train needs a carriage.

What happened there? Shall we see it

again?

Let's add some more carriages.

Blue one.

Green one.

Did you see how the carriages

attached together?

That's because of magnets.

These little silver dots.

Those are the magnets.

And when you put the carriages

together, they stick which

means you can pull the train around

the track like this.

Wheeee! Under the bridge.

When you finish playing,

you just pull the carriages apart

and the magnets become unstuck like

this.

But do you know how magnets work?

Let's find out.

Magnets are made of metal and

they're really fun to play with.

Look what happens when you put two

magnets together.

It feels like they're pulling

towards each other until

eventually, snap!

They pull together.

Did you hear the snap sound

the magnets made?

Look what happens if I turn

it the other way round

and use this magnet instead.

No matter how hard I try to push

them together,

they just don't want to connect.

This time it feels like they're

pushing away from each other.

Why does this happen?

On the end of each train

carriage are magnets.

They look the same but are

actually different.

Every magnet has two sides,

called poles.

One side is called the North Pole

and the other side

is called the South Pole.

And the whole magnet is

surrounded by an invisible

area called a magnetic field.

When a North Pole magnet goes into

the magnetic field

of a South Pole magnet,

they are pulled together.

But when you turn them around,

so the South Poles face each other,

the magnetic field pushes them away.

And the same happens if all the

North Poles face each other.

Only the opposites.

A North and a South Pole will pull

the magnets together.

So although the magnets look the

same, they're not.

And it's only when the opposite, the

North and South Pole are put near

each other, do you feel the pulling

and, snap, they come together.

If you turn the magnet the other way

round, so the poles are the same,

instead, you feel the magnets

pushing away from each other.

And, look, it's actually moving the

train all by itself.

So that pulling you feel

is the magnetic field around

the magnets starting to work and

this is called a magnetic force.

But to show you how strong a

magnetic force can really be,

I've got some other

magnets to show you.

Here, I've got two magnets.

This one has North and

South Pole clearly marked.

North is the red side and South is

the blue side. I've also got this

little silver magnet but I don't

know which side is which.

There's one way we can find out.

Did you see that?

The two magnets pulled together

so that means this side

of the silver magnet must be South

because South and North Poles

will pull together but it all

happened really quickly, didn't it?

I filmed this in super slow motion.

Take a look.

Look. As the magnets get close to

each other,

the magnetic fields start to work,

pulling the opposite poles together.

These little silver magnets are

actually really strong.

Now watch what happens when I run

the North and South Pole

magnet over the top.

Wow. It looks like magic,

doesn't it?

That is so much fun.

That's amazing.

The magnetic force is

so strong, it's making

the little silver magnets jump high

in the air to stick to

the North Pole.

I loved seeing how magnets worked.

What was your favourite bit?

Do you remember what you call the

two ends of the magnet?

That's right. They're called the

North Pole and the South Pole.

Did you hear the sound the magnets

made when they came together?

It was a big snap.

And did you see the way the magnets

jumped up high in the air

when the North and South Poles

were pulled together?

I've finished with my train set

so it's time

to put it away in the toy box.

But, look, here is Teddy.

Hello, Teddy.

Do you have a teddy bear?

They're lovely and soft,

aren't they?

But do you know how

a teddy bear is made?

Let's find out.

Well, I'm here in

a big teddy bear shop.

Just look at how many teddy

bears there are.

There are lots of different

types of teddy bear.

Today we're going to see how a teddy

bear just like this one is made.

Hello, Teddy.

And making a teddy bear all

starts with the fur.

This teddy's fur is made from

something called mohair which

comes from goat.

A type of goat called an

angora goat.

Next to the teddy bear shop is the

teddy bear factory.

And these are all the rolls

of mohair.

There are so many different colours.

This is Ian and Ian's going

to cut out the shape of

the new teddy bears in the mohair,

using this big machine.

Ian uses a different cutter for each

part of the teddy bear.

And he's starting with

the teddy bears' heads.

It's like a giant set of biscuit

cutters and uses the

big machine as a press.

Here we are. And, look,

can you see the little holes here

and here?

That's where the teddy bear's

eyes are going to go.

Next, Ian cuts out some

teddy bear bodies.

And then he cuts out some

arms and legs.

Because each teddy bear has two arms

and two legs, Ian puts

one layer of mohair on top of the

other so that when he starts

cutting he gets two of everything,

So this will become two teddy bear

legs.

When all the pieces have been cut

out,

they're taken to the next part

of the factory - the sewing area.

This lady here is sewing the teddy

bear arms and legs and that

lady is sewing the teddy

bear heads.

All of these pieces have been sewn.

We have arms, legs and a body.

But can you see that the fur

is on the inside?

That's because teddy bear parts

are sewn inside out.

So that when they're turned the

right way out,

all of the stitching is hidden.

So the next stage is for all of

these pieces to be turned

the right way out.

And look at this arm now.

The fur is on the outside and the

stitching is hidden on the inside.

So we have two arms,

two legs and a body but there's

one part missing.

Do you know what it is?

That's right. It's the head.

But before the head is turned

the right way out,

it needs a pair of eyes.

The eyes are made of plastic and

just look at all of them here.

Don't they look funny staring

back at us?

Each eye is popped through the small

hole in the teddy bear's head

and then Sharon uses

a special tool to pick up

a bit of plastic called a washer and

then she uses the tool to push

the washer over the eye and it

fixes it in place.

And now if we turn this teddy's

head the right way round,

you can see the eyes.

It's beginning to look like

a teddy bear, isn't it?

But all of these parts are

really flat.

This wouldn't make

a very cuddly teddy bear.

But that's because they need

to be stuffed.

All of this white fuzzy material is

teddy bear stuffing

and it's made from something

called polyester.

Let's use my special camera to take

a closer look.

But where is my special camera?

Oh, here it is.

This is a microscope and it helps us

to see really, really tiny things.

This is what the polyester stuffing

looks like in close-up.

Look at that. You can see all of the

little hairs, can't you?

It feels really soft but, actually,

under the microscope,

the little hairs look quite wiry.

It looks a bit like noodles,

doesn't it?

But how do we get this

stuffing inside a teddy bear?

INFLATING

Can you hear the sound the stuffing

machine is making?

It sounds like

a balloon being blown up.

And, here, we have one stuffed teddy

leg.

It feels nice and squishy now.

So we have the flat body,

stuffed arms, legs, and head.

Before all of these can be

joined together, something

clever happens.

And that's because these teddy bears

have something called joints.

You have joints in your body.

You have joints at the top of your

arms, called shoulders

and joints at the top of your legs,

called hips.

And they mean you can move

like this.

And our teddy is going to have arms

and legs which can move in

the same way.

The teddy bear joints are made with

long pins which are sewn

into the head, arms and legs.

The pins are then attached to the

body and fixed into place.

Then it's time to fill up the

body with stuffing.

And here's Teddy.

But he's got a hole in his back and

he's missing his nose and his mouth.

All of these get sewn over here.

There we go. Much better.

Now the fur is given a good

brush. Then it's time for

a trim and no teddy bear leaves

the factory without a ribbon.

There we go, Teddy. Looking good.

One last important check.

Yes, you are

lovely and cuddly.

I really loved seeing how

a teddy bear was made.

What was your favourite bit?

Do you remember what the teddy's

fur is made of?

That's right. It's mohair.

Did you hear the sound the

stuffing machine made when it

filled the teddy up?

And did you see what the

stuffing looked like

close-up when I used my

special camera?

So the next time you play with

a teddy bear,

you'll know how lots of

teddies are made.

And how they get to be so cuddly.

And now you know how magnets work.

And how they stick the carriages of

the toy train together.

Right, Teddy, it's time we're off.

I'll see you next time.
