0:40:530:40:55

Hello, everyone. I'm trying to find my book on cleaning. Aha!

0:40:560:41:00

There it is. Oh, but it's a bit dusty!

0:41:010:41:04

Oh... Oh....

0:41:070:41:09

Atchoo! Oh!

0:41:090:41:12

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

0:41:120:41:16

Hi, Nina!

0:41:200:41:23

Hi, guys!

0:41:230:41:24

We've got a question for you.

0:41:240:41:28

Why do some things make us sneeze?

0:41:280:41:31

That's a great question. Why do some things make us sneeze?

0:41:310:41:35

I've noticed that too.

0:41:350:41:36

In fact, some dusty dust just made me sneeze a minute ago!

0:41:360:41:40

Come down to my lab and we'll do some experiments to investigate.

0:41:400:41:44

ALL: See you soon, Nina. Bye!

0:41:440:41:48

I'm going to need some help and I know just who to ask.

0:41:480:41:52

OK, Neurons. Time to get to work.

0:41:520:41:54

ALL: Neurons at the ready, Nina.

0:42:110:42:13

OK. Today's question is why do some things make us sneeze?

0:42:130:42:18

Which Neuron do you think would be most useful in helping us?

0:42:180:42:22

ALL: Me! Me! Me!

0:42:220:42:24

Will it be fabulous Felix?

0:42:240:42:27

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

0:42:270:42:31

Will it be beautiful Belle?

0:42:310:42:33

I send messages to brain from ear,

0:42:330:42:35

if there's a sound, I'll help you hear.

0:42:350:42:38

Will it be lovely Luke?

0:42:380:42:39

For looking and seeing, day or night,

0:42:390:42:41

I'll help you with your sense of sight.

0:42:410:42:44

-Will it be awesome Ollie?

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

0:42:440:42:49

my messages help your sense of smell.

0:42:490:42:51

-Or will it be baby Bud?

-Sour, salty, bitter or sweet,

0:42:510:42:55

I'm your taste buddy whenever you eat.

0:42:550:42:59

-It's Ollie!

-CHEERING

0:43:010:43:04

ALL: Go Ollie! Go Ollie!

0:43:040:43:07

Go Ollie! Go Ollie! Go Ollie! Go Ollie! Go Ollie!

0:43:070:43:12

Standing by to smell and tell, Nina.

0:43:120:43:15

Today's question is why do some things make us sneeze?

0:43:150:43:19

Because we sneeze through our nose,

0:43:190:43:21

Ollie, our smell Neuron, will be helping us.

0:43:210:43:23

I'd better get the lab ready before the experimenters arrive.

0:43:230:43:27

Mika likes go-carting, Ryan likes camping

0:43:280:43:32

and Molly loves fajitas,

0:43:320:43:33

but they all want to know why some things make us sneeze.

0:43:330:43:37

So, today, Mika, Ryan and Molly become the experimenters.

0:43:370:43:42

-Hi, guys.

-Hi, Nina.

-Come on in. Welcome to my science lab.

0:43:430:43:49

You asked, "Why do some things make us sneeze?"

0:43:490:43:52

which is a great question

0:43:520:43:53

-But why do you want to know?

-Because sometimes we sneeze

0:43:530:43:56

-even when we don't have a cold.

-And we want to know why.

0:43:560:44:01

You're absolutely right. Lots of things can make us sneeze.

0:44:010:44:04

There must be a reason for all this sneezin'!

0:44:040:44:08

Let's do some investigating to find out more.

0:44:080:44:11

For our first experiment, we're using our senses.

0:44:110:44:14

ALL: Whoop-woo! A senses experiment! We're ready, Nina.

0:44:140:44:18

Sneezes often start with a tickle in our nose.

0:44:180:44:21

We're going to do an experiment to find out what might make our noses

0:44:210:44:25

itchy and tickly enough to sneeze.

0:44:250:44:27

So, we've all got some strong smelling peppercorns.

0:44:270:44:32

You've also got some fluffy feather dusters.

0:44:320:44:36

Your task is to test them on your noses to see if they tickle.

0:44:360:44:40

-But be careful not to stick anything up there.

-No! That could be painful!

0:44:400:44:45

We've put covers on these peppercorns so they can't escape.

0:44:450:44:50

So you're going to take a big sniff

0:44:500:44:52

and if you think you're going to sneeze, use a tissue.

0:44:520:44:56

Sneezing can spread nasty invisible germs that can make us ill.

0:44:560:45:00

Have a little shake of your peppercorns.

0:45:000:45:03

And sniff!

0:45:030:45:05

-What did they smell like?

-They smell quite spicy.

0:45:070:45:11

-Any sneezy feelings?

-My nose feels really scratchy.

0:45:110:45:17

The special stuff in pepper that can cause a tickle

0:45:170:45:20

is called piperine. Some of us are more sensitive to it than others.

0:45:200:45:24

Let me have a smell.

0:45:240:45:26

Can you feel the piperine, Felix?

0:45:300:45:32

Ah... Ah... Atchoo!

0:45:320:45:35

Atchoo!

0:45:350:45:38

I certainly can!

0:45:380:45:41

Ah...choo!

0:45:410:45:43

Oh! Ho-ho!

0:45:430:45:45

Peppercorns certainly can make us sneeze.

0:45:450:45:48

Let's try the feather dusters now. Give each other a gentle tickle

0:45:480:45:52

on the end of the nose.

0:45:520:45:55

THEY GIGGLE That was all over my face!

0:45:550:45:58

OK!

0:46:000:46:02

So what does that feel like?

0:46:040:46:06

-Very tickly.

-It gave me a tickly nose.

0:46:060:46:10

Yes. When things like a strong smell or a tickly feather

0:46:100:46:14

get inside our nose, it can react by feeling itchy.

0:46:140:46:17

This can make us want to rub it and our nose can also run a little.

0:46:170:46:21

If our noses are tickled and itchy enough, it can make us sneeze.

0:46:210:46:25

Some of us don't sneeze very easily, unless we have a cold,

0:46:250:46:30

but other people have really sneezy noses that get tickled

0:46:300:46:33

by all sorts of things that can be in the air.

0:46:330:46:36

-What sort of things make you sneeze?

-Flowers.

-The dust makes me sneeze.

0:46:360:46:42

So, our senses experiment has shown us that lots of things

0:46:420:46:46

can make a sneeze start. Now we need to find out what happens next.

0:46:460:46:50

I know just the place to race ahead with our discoveries. Let's go!

0:46:500:46:55

ALL: Yay!

0:46:550:46:57

-I wonder where Nina is taking us.

-Nina said "racing ahead".

0:47:010:47:06

Ah, yes! I love racing! I hope I win.

0:47:060:47:10

Winning isn't everything, Bud. It's just fun to take part.

0:47:100:47:14

Well, we're here and I don't think you'll be winning this race, Bud.

0:47:140:47:19

OK, I've brought you to this race track to show you something amazing

0:47:200:47:24

about sneezes. Watch very carefully as I pretend to sneeze.

0:47:240:47:29

But first, put on your ear defenders. It's going to get noisy.

0:47:290:47:34

How loud is Nina going to sneeze?

0:47:340:47:36

OK, here goes!

0:47:360:47:39

Ah... Ah...

0:47:390:47:41

-Ah... Atchoo!

-CAR ZOOMS

0:47:410:47:44

Ooh!

0:47:440:47:46

Wow! Nina just sneezed out a car!

0:47:460:47:49

It came from behind her, not out of her.

0:47:490:47:52

Ha-ha-ha! You're probably wondering what a racing car

0:47:520:47:57

has to do with sneezes. A sneeze travels at around the same speed

0:47:570:48:01

-as that racing car just did - 100 miles an hour.

-ALL: Wow!

0:48:010:48:06

That's why it's really important to cover your nose and mouth

0:48:060:48:11

with a tissue when you sneeze.

0:48:110:48:13

Because germs can fly out as fast as that car.

0:48:130:48:17

That's right, Ollie. We can't see the germs cos they're tiny bugs,

0:48:170:48:21

but some germs can make us ill, so after you sneeze into the tissue,

0:48:210:48:25

put it straight in the bin.

0:48:250:48:27

-Which part of our bodies do we use to sneeze?

-ALL: Our noses.

0:48:270:48:33

Yes! It starts with our nose, but we use many parts of our bodies

0:48:330:48:38

to sneeze. The sneeze starts when something tickles our nose.

0:48:380:48:43

The nose feels this and sends a message to our brain.

0:48:430:48:46

Our brain sends lots of instructions to different parts of our bodies

0:48:460:48:50

telling them it's time to sneeze.

0:48:500:48:53

Let's try a practice sneeze together so we see all the parts in action.

0:48:530:48:57

Put your hand just above your tummy and breathe in...

0:48:570:49:00

-What can you feel?

-ALL: It's getting bigger.

0:49:000:49:05

This is our chest filling with air.

0:49:050:49:07

When we sneeze, we push the air really quickly

0:49:070:49:10

up the windpipe and out. Now let's take another big breath.

0:49:100:49:14

This time, after three, we're going to let out a big sneeze.

0:49:140:49:19

One, two, three...

0:49:190:49:22

Atchoo!

0:49:220:49:25

We're only pretending to sneeze. A real sneeze happens all by itself

0:49:250:49:30

-because sneezing is what we call a reflex.

-What's a reflex, Nina?

0:49:300:49:35

A reflex is something our body does all by itself, like blinking,

0:49:350:49:38

or yawning. We don't need to think. Our body does it all on its own.

0:49:380:49:43

So we've discovered that sneezing is a reflex.

0:49:430:49:46

It uses lots of parts of the body, not just our nose,

0:49:460:49:50

and travels at 100 miles an hour, just like a racing car.

0:49:500:49:55

But why does it do this?

0:49:550:49:57

-Let's go back to the lab for one final experiment.

-ALL: Yay!

0:49:570:50:02

OK, these air cannons are going to be our pretend noses.

0:50:030:50:08

If you watch carefully, I'm going to pull this out

0:50:080:50:14

and...let it go!

0:50:140:50:17

Ha-ha-ha! What did you feel?

0:50:170:50:19

Wind.

0:50:190:50:21

That's right. A blast of air comes out, just like a sneeze.

0:50:210:50:25

And you're going to fill up these pretend noses

0:50:250:50:28

with some tickly feathers.

0:50:280:50:30

You should never put anything up your nose, Nina.

0:50:300:50:33

That's right, Ollie. We're putting feathers into our pretend noses

0:50:330:50:38

for the purposes of our experiment. We'd never do it with a real nose.

0:50:380:50:42

OK, guys, get filling!

0:50:420:50:44

The tickly feathers are in. It's time to get those noses sneezing.

0:50:500:50:55

OK, so everyone carefully pick up your air cannon

0:50:550:50:58

and face the feathers away from you.

0:50:580:51:01

That's it.

0:51:010:51:03

And on my command,

0:51:030:51:05

Ryan, go!

0:51:050:51:07

Look at those feathers flying.

0:51:070:51:10

Mika, go!

0:51:100:51:12

Molly, go!

0:51:120:51:14

Ay!

0:51:150:51:17

Brilliant! That was superb!

0:51:170:51:21

What does this experiment tell us about sneezes?

0:51:210:51:24

What do you think a sneeze might be doing to help your nose?

0:51:240:51:28

-Getting rid of the thing that's tickling it.

-That's right.

0:51:280:51:31

When a nose feels something inside it that shouldn't be in there,

0:51:310:51:36

we sneeze. The sneezing reflex is trying to blast away

0:51:360:51:40

whatever the tickly thing is.

0:51:400:51:42

Your question was, "Why do some things make us sneeze?"

0:51:470:51:50

And I think we've answered it. We discovered sneezing is a reflex,

0:51:500:51:55

which means it's something the body does all by itself.

0:51:550:51:58

Sneezing often starts when something tickles inside our nose.

0:51:580:52:02

This can be a strong smell, something tickly like a feather,

0:52:020:52:06

or dust that gets into our nose and makes it itchy.

0:52:060:52:10

Our nose doesn't like having things inside it.

0:52:100:52:13

If it feels something tickling, the nose sends a message to the brain

0:52:130:52:16

to make us sneeze to get rid of the tickly thing.

0:52:160:52:20

The sneeze can blast out at a super-speedy 100 miles per hour,

0:52:200:52:24

spreading lots of invisible germs.

0:52:240:52:27

That's why we must always sneeze into a tissue

0:52:270:52:30

and throw it in the bin. I hope that's answered your question.

0:52:300:52:34

-ALL: Thanks, Nina. Bye!

-Bye.

Nina investigates why some things make people sneeze, with the help of Ollie, her smell neuron.

Experimenters Mika, Molly and Ryan visit Nina in her lab and find out that people sometimes sneeze when something irritates or tickles their nose, like a strong smell or a tickly feather. They go to a racetrack and discover that sneezes can travel as fast as a racing car - a super-speedy 100 miles per hour! They learn why it is important to cover your nose when you sneeze - it can blast out nasty germs that can make other people ill.

Back at the lab, they do an experiment with air canons and work out that a nose sneezes to get rid of the thing that's tickling it. Nina explains that this is a reflex action - something the body does all by itself, without thinking about it.
