0:00:530:00:55

Hello. I'm cleaning the lab and dusting Mr Skeleton

0:00:560:01:00

with my feather duster.

0:01:000:01:02

-Tickle, tickle, tickle.

-BEEP BEEP BEEP

0:01:020:01:05

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

0:01:050:01:10

-BOTH: Hi, Nina!

-Hello!

-We've got a question for you.

0:01:130:01:18

Why are our feet so ticklish?

0:01:180:01:20

That's a great question. Why are our feet so ticklish?

0:01:200:01:24

My feet are very ticklish but I've never thought about why.

0:01:240:01:28

Come down to the lab and we'll investigate.

0:01:280:01:31

BOTH: See you soon, Nina. Bye!

0:01:310:01:36

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

0:01:360:01:40

OK, Neurons, time to get to work.

0:01:400:01:43

ALL: Neurons at the ready, Nina.

0:01:590:02:02

OK. Today's question is why are our feet so ticklish?

0:02:020:02:06

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

0:02:060:02:10

ALL: Me! Me! Me! Oh, me!

0:02:100:02:12

Will it be fabulous Felix?

0:02:120:02:14

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

0:02:140:02:18

Will it be beautiful Belle?

0:02:180:02:21

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

0:02:210:02:26

-Will it be lovely Luke?

-For looking and seeing, day or night,

0:02:260:02:30

-I'll help you with your sense of sight.

-Will it be awesome Ollie?

0:02:300:02:34

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

0:02:340:02:37

-my messages help your sense of smell.

-Or will it be baby Bud?

0:02:370:02:41

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

0:02:410:02:47

Oh, it's Felix!

0:02:490:02:52

ALL: Go, Felix! Go, Felix!

0:02:520:02:54

Go, Felix! Go, Felix! Go, Felix! Go, Felix!

0:02:540:03:00

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

0:03:000:03:05

Today's question is why are our feet so ticklish?

0:03:050:03:08

Tickles are something you feel, so Felix our touch Neuron will help us.

0:03:080:03:13

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

0:03:130:03:17

Zoe likes jacket potatoes and Brier likes tangerines.

0:03:190:03:23

They both want to know why our feet are so ticklish.

0:03:230:03:27

So today, for one day only, Zoe and Brier become the experimenters!

0:03:270:03:32

-Hi, guys.

-BOTH: Hi, Nina!

-Welcome to my science lab.

0:03:350:03:39

Your question is why are our feet so ticklish

0:03:390:03:43

but why do you want to know?

0:03:430:03:46

Our feet are very ticklish and it's a funny feeling.

0:03:460:03:49

But we want to know WHY our feet are so ticklish.

0:03:490:03:53

Many parts of our bodies can be ticklish.

0:03:530:03:56

Armpits, necks, tummies, but feet do seem to be especially ticklish.

0:03:560:04:01

We need to experiment to find out more.

0:04:010:04:03

Let's use our senses.

0:04:030:04:05

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

0:04:050:04:10

Brier, you and I will sit here, and Zoe, you're going to try

0:04:100:04:14

and tickle us using a very hi-tech piece of ticking equipment.

0:04:140:04:19

-What do you think that is?

-Fingers.

-Yes, fingers.

0:04:190:04:22

Fingers are brilliant tickling tools. Brace yourself, Brier.

0:04:220:04:27

OK, get tickling.

0:04:270:04:29

-Hee-hee!

-Ha-ha!

0:04:290:04:33

-Ha-ha!

-Hee-hee!

0:04:330:04:37

Ha-ha! Ha-ha!

0:04:370:04:40

How would you describe the tickly feeling?

0:04:400:04:43

Like a feather on your foot!

0:04:430:04:45

It's a sort of itchy, shivery sensation, Nina.

0:04:450:04:49

-And do you like the feeling?

-Yes!

0:04:490:04:51

And Zoe, what do you see happening to our feet and our toes

0:04:510:04:57

when you're tickling them?

0:04:570:04:59

-They're scrunching up!

-Yeah!

0:04:590:05:01

-Our feet are trying to escape from the tickle touch!

-Ha-Ha!

0:05:010:05:05

Oh, I can't bare it any more! Please, stop!

0:05:050:05:09

Did you notice the tickling made us pull our feet away?

0:05:090:05:13

Yes, I couldn't bear it!

0:05:130:05:16

Some people believe this is because our body thinks

0:05:160:05:20

the tickle could be an insect sneaking up on us.

0:05:200:05:25

Some insects bite, so our body makes us shake it off or move away.

0:05:250:05:29

Zoe, can you try tickling us again but not so light a tickle touch.

0:05:290:05:34

Off you go!

0:05:340:05:36

-Oh...how does that feel this time?

-Hmm...not so ticklish.

0:05:360:05:43

So our senses experiment has shown us that tickles only happen

0:05:430:05:47

when something touches our skin very lightly.

0:05:470:05:50

How do our bodies know when they are being tickled?

0:05:500:05:54

We need to go somewhere with lots of tasty treats!

0:05:540:05:57

-Let's go, experimenters!

-BOTH: Yay!

0:05:570:06:00

-I wonder where Nina is taking us.

-Nina mentioned tasty treats.

0:06:030:06:08

Perhaps, it's a fruit market with sweet-smelling strawberries.

0:06:080:06:13

Or a supermarket with cheese, ham, broccoli, beans and...

0:06:130:06:17

Och, I'm starving!

0:06:170:06:19

We're here! And it sure looks like we're in for a yummy surprise.

0:06:190:06:24

-Hi, Aileen.

-Hi, Nina.

-This is Aileen. She's a chef.

0:06:240:06:29

It's her job to make tasty treats for people.

0:06:290:06:32

-What have you got cooking?

-I've made a sticky toffee pudding.

0:06:320:06:36

-Shall we see if it's ready? ALL: Yes!

-Yes!

0:06:360:06:39

The pudding is just out of the oven so it's very hot.

0:06:410:06:45

Part of chef's job is to make sure the food is warm and cooked enough,

0:06:450:06:49

but not too hot, in case it burns their mouths.

0:06:490:06:53

So she'll use this, a sensor. Sensor means feeler

0:06:530:06:59

and this clever little box can feel how hot or cold our food is.

0:06:590:07:03

You put the spike into the food and it gives you a number on the screen.

0:07:030:07:08

The bigger the number, the hotter the food is.

0:07:080:07:11

The smaller the number, the colder the food. Let's test the pudding.

0:07:110:07:16

Oh, yep, that's definitely too hot to eat.

0:07:160:07:20

Let's test another food while the pudding cools down.

0:07:200:07:24

-Does anybody like ice cream?

-Yes! We all love ice cream.

0:07:280:07:32

-Do you think ice cream would be hot or cold?

-Definitely cold.

0:07:320:07:37

Let's see. Can you put the sensor into the ice cream for me, Brier?

0:07:370:07:43

You're right. The number is small

0:07:440:07:47

because the ice cream is very cold.

0:07:470:07:51

And our feet can sense hot or cold too.

0:07:510:07:55

But they can also sense lots of other things, like tickly tickles.

0:07:550:07:59

That's because our feet contain nerves.

0:07:590:08:02

I use nerves to feel things for Nina.

0:08:020:08:05

Yes, you do, Felix.

0:08:050:08:08

We have nerves in our skin all over our bodies

0:08:080:08:11

and the nerves act like sensors.

0:08:110:08:14

Some nerves sense hot and cold

0:08:140:08:16

and other nerves can sense a really light touch of a sneaky tickle.

0:08:160:08:21

Oh! Sticky toffee pudding!

0:08:210:08:25

-Thanks, chef.

-Enjoy!

0:08:250:08:27

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

0:08:380:08:43

OK, Zoe, your shoes are off and you'll find out why

0:08:450:08:48

I've asked you to take your lab coat off.

0:08:480:08:51

Brier, you'll be the top tickler for this experiment.

0:08:510:08:55

I have here for you an extra large, extra soft, extra tickly feather!

0:08:550:09:00

Woo-hoo!

0:09:000:09:02

Oh, lots of touchy, feely tickles! Marvellous.

0:09:020:09:06

This experiment will test different parts of Zoe's body

0:09:060:09:10

to see how ticklish they are.

0:09:100:09:12

Zoe, your job is to stay nice and still

0:09:120:09:15

and try not to react to the tickling. Can you manage that?

0:09:150:09:19

Will you try your best? Great. I'm going to mark on this chart

0:09:210:09:25

whether each body part

0:09:250:09:28

is very tickly or not very tickly.

0:09:280:09:31

Everybody ready?

0:09:310:09:33

OK, so forehead first. Get tickling.

0:09:330:09:37

-How does that feel?

-It's OK, Nina. But not really tickly.

0:09:400:09:44

So Zoe's forehead isn't very tickly.

0:09:440:09:48

Next, let's try back of the hand.

0:09:480:09:51

Not too tickly?

0:09:540:09:56

It's OK, but not very tickly.

0:09:560:09:59

Not very tickly. Ah-ha! It's armpits next!

0:09:590:10:05

Oh, great! Prepare to hear some giggling!

0:10:050:10:09

-Oooo! Ha-ha!

-Hee-hee.

0:10:130:10:15

-You're supposed to be staying still!

-Yes, Nina, but it's very tickly.

0:10:150:10:21

OK, so let's put armpit down as very tickly.

0:10:210:10:25

Last of all, it's feet. Get that extra large, extra soft,

0:10:270:10:31

extra tickly feather tickling those feet.

0:10:310:10:34

-Hee-hee!

-Ha-ha!

0:10:340:10:37

I don't even need to ask what I'm marking for feet!

0:10:370:10:41

A big tick next to very tickly.

0:10:410:10:43

This experiment has shown us that Zoe's forehead and back of hand

0:10:430:10:48

aren't particularly ticklish,

0:10:480:10:50

but her armpits and feet are very ticklish indeed.

0:10:500:10:54

This diagram should help us explain why.

0:10:540:10:57

This is the body.

0:10:570:11:00

And these little dots are the nerves that sense tickles.

0:11:000:11:04

Different types of nerves in our skin sense different things.

0:11:040:11:09

Some nerves sense hot and cold, and others, like the ones shown here,

0:11:090:11:14

sense the really light touch of a tickle.

0:11:140:11:17

-Can you see many tickle nerves in the forehead?

-BOTH: No, Nina.

0:11:170:11:22

Where are there lots of the nerves that sense tickles?

0:11:220:11:26

-BOTH: In the feet.

-That's right.

0:11:260:11:29

Zoe, you said your forehead wasn't ticklish and that's because

0:11:290:11:34

most of us have hardly any nerves that sense tickles in our foreheads.

0:11:340:11:40

Your feet could hardly bear to be tickled and that's because

0:11:400:11:44

most of us have more tickle nerves in our feet than anywhere else.

0:11:440:11:49

Your question was why are feet so ticklish?

0:11:540:11:57

And I think we've answered it.

0:11:570:11:59

Tickles are caused by something touching our skin lightly.

0:11:590:12:03

A bit like an insect.

0:12:030:12:05

When something tickles us, nerves in our skin send a message to our brain

0:12:050:12:10

and this makes our body wriggle

0:12:100:12:13

as it tries to escape the tickle and it can often make us laugh.

0:12:130:12:18

Everyone's body is different, but many of us have more nerves

0:12:180:12:22

that sense tickles in our feet than anywhere else.

0:12:220:12:26

This is why our feet can feel more ticklish than the rest of our bodies

0:12:260:12:30

so I hope that's answered your question.

0:12:300:12:33

-BOTH: Thanks, Nina. Bye!

-Bye!

0:12:330:12:36
