Hi, everyone.

Hi, Nina!

I have a fantastic experiment to show you using these two liquids.

They look pretty normal, don't they?

-Yes.

-Yeah?

Nothing special about them.

But watch what happens when I mix this luminal powder.

I'll just pop some in there. That should be enough.

Can I have the lights dimmed, please?

Wow!

Isn't that fantastic?

Looks brilliant! It's glowing really brightly.

When luminal powder mixes with different liquids,

it causes a chemical reaction

which gives off lots of little flashes of light.

Lights back up, please.

Did you know some animals can do this too?

Like glow-worms, fireflies and even some fish glow in the dark

just by using the chemicals in their bodies.

APPLAUSE

BLEEP! BLEEP!

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

Hi, Nina, I'm Alex, I've got a question for you.

How can we stop bread going mouldy?

That's a great question! We'll have lots of fun finding this out.

-I'll be round soon to answer your question.

-See you soon, bye.

Bye.

I'll need help to answer this one and I know just who to ask.

OK, Neurons, time to get to work.

Neurons at the ready, Nina.

OK, today's question is how can we stop our bread from going mouldy?

Which neuron will be most useful for finding the answer?

-NEURONS:

-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 help you hear.

Will it be lovely Luke?

For looking and seeing, day or night,

I 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 when you eat.

-It's Luke!

-Yes!

Go, Luke! Go, Luke! Go, Luke! Go, Luke! Go, Luke!

Cool, Nina, I'll be looking out to help you!

Thanks, Luke.

The question is how can we stop bread going mouldy?

In order to answer we'll do a lot of looking, so Luke will help us.

But standby, Neurons, I may need all of you.

OK, let's go.

Alex will be finding out about mould

green mould, brown mould, long fluffy, hairy mould.

Today, for one day only, Alex and her brother John become,

The Experimenters!

-Hi, guys!

-Hi, Nina!

Hi, Alex, thanks for your great question about mould.

Why did you ask me about mould?

Sometimes mould grows on the bread and we have to throw it away.

You wouldn't want to eat mouldy bread!

No! So to answer your question, we need to find out all about mould,

to do that we need to go back to my lab.

Luke, are you ready to help?

At your service, Nina.

OK, let's go!

To most people, mould is disgusting

but to a scientist like me, it's fascinating!

In fact, I've even been growing my own mould!

But first, of all,

let me show you some fresh samples.

Ooo, now we've got some soft cheese,

some jam,

and some fruit.

No mould on it at all.

So, let me show you another sample. Sit that there.

Here is the sample that HAS got mould on it.

Gross!

Look at all that mould that's been growing.

That's amazing!

Ha-ha! It's covered in green fuzzy hair, like tiny monsters!

Mouldy foods can make you feel unwell, you have to be careful.

Now, mould grows on other things, not just bread.

I had an orange in my school bag and it went black and mouldy.

That's right, different moulds grow on different food.

Let's have a closer look down here.

Lots of different types of moulds, all different colours and shapes.

Not all moulds are bad for you.

Some cheeses are deliberately mouldy,

and some special moulds help fight disease.

But ones that grow accidentally on your food are definitely bad for you.

These samples have grown for two weeks.

Shall we see some that have been growing for four weeks?

Yes, please.

-What do you think they'll be like?

-Bigger.

Hairier.

No! No, no, no, not the hairy, mouldy, monster food! Argh!

Hee hee! You make me laugh, Bud!

Bud, shush! Let's listen to what Nina has to say.

There's much more mould on the older food.

Mould is a bit like us, it likes eating food,

so the more time it has to eat, the bigger it gets.

The longer we leave food, the more likely it is to grow mouldy.

But we haven't answered your question,

I've got an idea for an experiment.

We'll have to go back to the house, come on, let's go!

OK, where do you normally keep bread?

-In the bread bin.

-My goodness, what a lot of bread!

Mmm, I do love the smell of fresh bread.

-What's that bread, there?

-That's left from yesterday's picnic.

Left over bread! That's perfect for our experiment.

Let's start by putting it into some bags.

Bring it over, John.

Excellent, so one slice there.

Alex, you put this piece somewhere warm, like the airing cupboard.

Oh, it'll be lovely and warm in there.

John, you put this piece somewhere very cold like...

-Freezer!

-Good idea.

And I'll put a piece back in the bread bin where it's normally kept.

Off you go!

Oh, hello! Look, there's one piece of bread left.

Where will we put that one?

I was thinking I'd take it home with me.

Mmm, maybe Nina's going to eat it when she gets home.

As if Nina would eat an experiment, Bud!

Now what we'll do is leave the bread where it is for two whole weeks.

Then I'll come back and see if there's been any changes.

-Is that OK with you?

-Yes!

-Yes!

-Excellent.

OK, see you soon, bye!

-See you soon, Nina.

-Bye.

RING!

-Hi, guys.

-Hi, Nina.

-Hi, Nina.

-Have there been any changes in the bread?

-Yes.

-Yes.

-Quite a lot.

-Let's collect them. I'll meet you in the kitchen.

OK, just pop them up there for me.

-And where was this one kept?

-The freezer.

-Oh.

Oh, that's very firm and hard, Nina.

It sounds like a piece of wood.

It's frozen solid and look, there's no mould on it at all.

We can't eat it if it's frozen, we'd have to wait to defrost it.

Let's look at the next one.

I collected this one from the bread bin. That's interesting.

This one's definitely soft, but there's a bit of mould on there.

So let's have a look at the next one.

Oh! Oh-oh-oh!

Whoa! That's one big, furry piece of bread, Nina.

You're right, this one's really mouldy. Where was this?

-In the airing cupboard.

-Why do you think this is mouldy?

Because the airing cupboard's warm.

The airing cupboard is warm. So from our experiment

we've discovered that mould grows quicker in warm places.

If you want bread to stay fresh for the longest time,

keep it in a cool place.

So is the bread bin in a warm place or a cool place?

It's quite cool, but it's right next to the cooker and the toaster,

so it could get warm at times.

In that case, we should move the bread bin to an even cooler place

perhaps over here.

There we go. Even in a cool place,

if you leave bread long enough, it will go mouldy.

Nina, where's the bread you put in your bag?

Um, actually I ate it on the way home last week!

Hee hee! I remember you did, Nina, and it was very tasty!

But I did eat it for a scientific reason.

Eating fresh food is the best way to stop it going mouldy.

The piece I took away didn't go mouldy at all.

We should eat the food we buy before it goes mouldy

so we don't waste good food.

We've got lots of bread. Maybe we've bought too much.

If we don't want to waste food, we shouldn't buy too much.

We should only buy what we need.

So, Alex, your question was, how can we stop our bread going mouldy?

We found out that it's not just bread that goes mouldy.

We also saw mould on cheese and jam

and the longer we left it the more mould there was.

We discovered that mould grows quicker in warm places.

and slower in cool places and it doesn't grow at all in a freezer.

So we moved our bread bin to a cooler place.

The best way to stop mould growing on food

is to eat it before it goes mouldy

so it doesn't get wasted, which helps protect our planet.

Thanks, Nina.

-Bye, guys.

-Bye, Nina.

-Bye, Nina.

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

All those different types of mould were so cool to look at.

Oh, I've had a brilliant day

listening to Nina explaining all about mould and how it grows.

I really enjoyed myself today,

smelling all that delicious fresh bread. Mmmm!

I've had a fabby day!

Hiding the slices of bread in different places was great fun.

We've had a sensational time today, I hope you've enjoyed it too. Bye.

Bye!
