Hello. I'm doing an important experiment -

how long does it take to eat a sticky bun?

The result is, it was very quick. I'm almost finished! Ha-ha!

ALARM BEEPS

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

ALL: Hi, Nina!

Hi, guys!

We've got a question for you.

-Why does jam make our hands sticky?

-That's a brilliant question!

Why does jam make our hands sticky?

I've just eaten a bun that made my hands sticky too.

Come to the lab, we'll do some experiments to investigate.

ALL: See you soon, Nina. Bye!

Bye!

I'll need some help to answer this one.

I know just who to ask.

OK, Neurons, time to get to work.

ALL: Neurons at the ready, Nina.

OK. Today's question is, why does jam make our hands sticky?

Which Neuron will be most useful to help find the answer?

ALL: Me! Me! Me! Oh, 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!

It's Felix!

CHEERING

ALL: Go, Felix! Go, Felix! Go, Felix! Go, Felix!

Go, Felix! Go, Felix!

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

Today's question is, why does jam make our hands sticky?

Being sticky is something we can feel,

so Felix our touch Neuron will help.

I need to get the lab ready before the experimenters arrive.

Nathan likes cartoons.

Patricia loves music.

Ben likes trampolines.

They all want to find out why jam makes their hands sticky,

so today, for one day only, they become the experimenters!

-ALL: Hi, Nina.

-Hi, guys!

Welcome to my lab. Come in.

Come in!

Now, you asked, why does jam make our hands sticky?

Which is a brilliant question, but why do you want to know?

When I have toast and jam in the morning, my hands get sticky.

Mine too! You have to wash them really well to get all the jam off.

For our first experiment, we're going to use our senses.

ALL: Whoop-whoo! A senses experiment!

We're ready, Nina.

-Remember you said you put jam on your toast?

-Yes.

For this experiment, we'll forget all about the toast

and put the jam straight onto our hands! Ho-ho!

So hands out, please.

Hee-hee!

Ha-ha-ha!

Ooh!

-Mmm! Strawberry! My favourite!

-When's tasting time, Nina?

Sorry, Bud! We're not tasting the jam,

we're feeling it.

Ah! I'm the Neuron for that job.

-What does it feel like?

-Sticky.

-Sticky.

Yeah! Oh-ho-ho-ho!

Nina's fingers are almost stuck together.

So they are! The jam is sticking my fingers together,

a bit like glue. What other foods are sticky?

-Toffee.

-Lollies.

-Honey.

-They're all pretty sticky, aren't they?

So we've found out that when something is sticky,

it makes things stick or join together a little.

I think we need to wash our hands and get all the sticky jam off

because I have another jammy experiment to show you.

For this experiment, we're going to have a food race!

A food race?! To see how much food we can taste, Nina?

No, we're not tasting anything, Bud.

Aw!

Here we have four dishes, and in this one we have some syrup,

some olive oil,

some ketchup

and jam, but not too much because it's not good to waste food.

We'll see which one reaches the bottom first.

-Who do you think will win?

-Syrup.

-Syrup, OK.

-Oil.

-The oil. What do you think, Ben?

-Jam.

Oh! Well, let's see.

OK, ready?

On your marks,

go!

Come on, Ketchup!

The olive oil's running away with it! Ha-ha!

The syrup's picking up pace. The ketchup needs to catch up.

Do you get it? Ketchup, catch up?

Oh, never mind.

We have a winner! The olive oil reached the bottom first.

The oil is much runnier than the others,

so it ran down the board really quickly.

If we touch a tiny bit of oil... Have a feel.

It's not really sticky, is it?

I'd say that was more oily than sticky.

So the thick ketchup is the slowest in the race,

-but where's the jam?

-It's not reached the bottom yet.

So the jam is not a fast runner, because it's quite thick and sticky.

So the jam's stickiness

slowed it down because it kept sticking to the board.

I think we need to go to a very special place

where there's lots of lovely jars. Let's go!

-ALL: Yes!

-Woo-hoo!

Off we go, for another adventure.

Nina said it was somewhere with lots of jars.

Oh, I know! The supermarket! There's lots of jars there.

I have a feeling we're here, Neurons.

This is it, experimenters. Any ideas what's inside?

ALL: No.

Well, let's go in. I have a feeling

it's going to be jam-packed with things for us to see! Let's go.

Here we are, everyone, at a jam factory!

We're going to see jam being made. Ha-ha!

Wooo... What a lovely fruity smell.

So all the fruit is put into these big pots,

and boiled until it breaks down into a gooey liquid.

And then they put in syrupy liquid sugar,

and boil it some more to make it thicker.

This is the syrupy sugar here.

It's a bit like the syrup from our food race.

Woo-hoo-hoo-hoo! So let's see what happens next.

We now have our very own jar of jam!

-Shall we taste it?

-ALL: Yeah.

OK! Here we go...

About time too, Nina.

Ooh-hoo...

Mmm...

Ha-ha! Look at their messy faces.

-They're covered in jam.

-And Nina's got sticky fingers. Again.

Mmmmm... But it tastes sweet!

You're right, Bud. It does taste sweet.

Really sweet.

Fruit has some sugar in it naturally,

and liquid sugar was added to the bubbling pots too.

So sugar makes the jam taste sweet.

Oh - but that doesn't tell us WHY it's sticky, does it?

ALL: No.

No. So I think we need to do one final experiment.

So your question was, why does jam make our hands sticky?

We've learnt that when something is sticky,

it makes things stick or join together - like glue.

And when we went to the jam factory,

we discovered that jam is made from fruits and syrupy sugar.

But we still don't know why jam is so sticky.

-So let's get experimenting!

-ALL: Yeah!

OK, we're going to test this water

to see how sticky it is.

The water needs to be quite hot,

but I've checked, and it's not burny-hot.

So let's dip our hands in...

So is that sticky?

No.

No? It's not sticky at all, is it? So let's add a little bit of sugar.

OK, Patricia - you want to turn your tap?

That's it!

And now do you want to take your mixing stick,

and give it a good stir?

That's great, Patricia. Thank you.

Now, let's rub a little bit on our hands.

That's it.

No. That's still not sticky.

Let's add a bit more sugar. Ben, your turn - turn the tap.

And what do they feel like now?

It feels stickier.

Yeah? Oh, it does. My hands are starting to join together a bit.

Nathan - go for it.

Oh, it's going to be VERY sticky now.

-Oh, what does it feel like now?

-Very sticky.

Very sticky, yeah!

It's even stickier than lolly bits.

Oh, really, really sticky!

My fingers are sticking together.

I think we need to wipe them with a tissue.

Oh...!

Sticking instead.

Oh! Our hands are so sticky

that the paper tissue's sticking to them.

What does this experiment tell us?

The sugar made the water sticky.

That's right. The more sugar that we added to the water,

the stickier it got.

And there's only one way to get this much stickiness off -

some soap and water. So we better wash our hands!

Oh... That's better.

Now, your question was,

why does jam make our hands sticky? And I think we've answered it.

We learnt that jam is made from fruit, and lots of sweet sugar.

Our final experiment proved

that it's the sugar in jam that makes it sticky.

-So I hope that's answered your question.

-ALL: Thanks, Nina. Bye!

Bye!

Safety gloves on, Felix.

Don't forget your goggles, Nina.

Goggles are on, Luke. I think we're ready!

It's been a marvellous day. And a very busy one.

I've been feeling sticky things all day long.

Ah, it's been such a great day, man.

Seeing all that running in the food race - that was pretty fun!

I really enjoyed myself today.

The smell of the jam being made in the factory...

Mmmm! Delicious.

Oh, I've had a brilliant day.

Hearing everyone laughing and giggling when they got really sticky

was ace!

Our day's been bursting with sensational experiments.

See you soon. Bye!

ALL: Bye!
