00:05If you've got a question and you don't know where to go,
00:08ask Nina for some help, cause she's got a science show.
00:11She makes sense of her senses by helping all her fans.
00:14By doing her experiments with potions and with bags.
00:17Touch her tongue.
00:19Fingers.
00:20Eyes.
00:21Here's here.
00:22Notes.
00:23Nina and the neurons find out what you need to know.
00:26Nina and the neurons find out what you need to know.
00:30Look, he helps us with our eyes and Felix with our touch.
00:32Ollie sniffs our smells and sounds and bells she hears so much.
00:35But it's Ollie's brother, he helps us with our taste.
00:38Then Nina's little neurons and they're coming to your place.
00:41Touch her tongue.
00:42Tongue.
00:43Fingers.
00:44Fingers.
00:44Eyes.
00:45News.
00:46Notes.
00:47Nina and the neurons find out what you need to know.
00:50Yeah!
00:51Nina and the neurons find out what you need to know.
00:53Oh, yeah!
00:57Oh, hello.
00:58It was my birthday yesterday and I had such a lovely time with balloons and presents and
01:05this beautiful birthday cake.
01:07But I think I should have blown the candles out a bit quicker.
01:09I spent so long making a wish that the candle wax melted onto the cake.
01:14Oops.
01:18I hear a beep.
01:19I see a flash.
01:20I wonder what they're going to ask.
01:28Hi, Nina!
01:30Hi, guys.
01:31We've got a question for you.
01:33What is earwax for?
01:34That's a great question.
01:36What is earwax for?
01:38Our brilliant bodies do make a kind of wax in our ears.
01:42But what is it doing there?
01:44Why don't you come down to my lab and we'll do some experiments to investigate.
01:48See you soon, Nina.
01:50Bye.
01:51Bye.
01:52Well, I'm going to need some help to answer this one and I know just who to ask.
01:56Okay, neurons.
01:56Time to get to work.
02:18Okay, today's question is what is earwax for?
02:21Now, which neuron do you think will be most useful in helping us find the answer?
02:25Me.
02:26Me, me, me.
02:27Me.
02:28Will it be Fabulous Felix?
02:31I can help so very much if you need the sense of touch.
02:34Will it be Beautiful Belle?
02:36I send messages to Brain from ear.
02:39If there's a sound, I'll help you hear.
02:41Will it be Lovely Looks?
02:43For looking and seeing, day or night, I'll help you with your sense of sight.
02:47Will it be Awesome Ollie?
02:49If it's Pony or Withy but you can't tell, my messages help your sense of smell.
02:54Or will it be Baby Bud?
02:56Salty, Salty, Bitter or Sweet.
02:59I'm your taste buddy whenever you eat.
03:05It's Belle.
03:07Yes.
03:08Go Belle.
03:09Go Belle.
03:10Go Belle.
03:11Go Belle.
03:13Go Belle.
03:14Go Belle.
03:14Go Belle.
03:15Brilliant.
03:16I'm all ears, Nina.
03:19Today's question is what is earwax for?
03:22And because it's all about our ears, Belle will be helping us today.
03:25But stand by neurons, I have a feeling I may need help from all of you.
03:28Right, I need to get the lab ready before the experimenters arrive.
03:33Evie likes riding her bike, Josh likes painting and Xanthi loves jam sandwiches.
03:39But they all want to know what earwax is for.
03:41So today, for one day only, Evie, Josh and Xanthi become the experimenters.
03:49Hi guys.
03:51Hi, Nina.
03:52Oh, welcome to my science lab.
03:54Come in.
03:56Now, your question is what is earwax for?
04:00Which is a great question.
04:02But why do you want to know?
04:03It's a bit strange having wax in our ears.
04:06Why is it there?
04:07Yes, it does seem a funny thing for our brilliant bodies to make.
04:11But remember, we should never put our fingers in our ears to feel it.
04:15No, that would make our ears very sore.
04:19It certainly would, Belle.
04:21But earwax must be there for some reason.
04:24So I think we need to do some investigating to find out more.
04:27And for our first experiment, we're going to use our senses.
04:31Whoop, whoop!
04:32A senses experiment!
04:34We're ready, Nina!
04:36There are lots of different types of wax in the world.
04:39Now, these candles are made of a type of wax.
04:42So let's touch them and tell me what they feel like.
04:47Hard.
04:48Smooth.
04:50They feel sort of slippery and greasy.
04:54Greasy?
04:55That's just what they feel like.
04:57Okay, now, pop your finger in there.
05:00What does that feel like?
05:01Gooey.
05:03Slimy.
05:03Well, this is called styling wax.
05:06And you're right, it is gooey and slimy.
05:09So we know that wax can be hard and greasy and it can be soft like the styling wax.
05:16Who recognizes these?
05:18Crayons.
05:19Crayons crayons.
05:19It's a crayon, that's right.
05:21So crayons are made of a type of wax too.
05:23I'd like you to pick a crayon and colour in your shapes.
05:39Well done guys, that was some great colouring in.
05:42Now, what does the crayon on the paper look like?
05:46Colourful and shiny.
05:47Yes, and it's also waterproof.
05:50What does waterproof mean?
05:52Well, it means that it keeps water out.
05:55Let me show you.
05:56Now, I've got a dropper here with some water in it.
05:59I'm going to put it onto this sheet of paper.
06:05Oh, it's getting all wet.
06:08The water is soaking into the paper and making it really wet.
06:12Now, why don't you try putting some water onto your crayon pictures?
06:18And squeeze.
06:20So what can you see?
06:22The water is sitting on top of the wax.
06:26Yes, so we know that wax can be hard and greasy and soft and squidgy and it's waterproof.
06:33But we still don't know why we have wax in our ears.
06:37So I think for our next experiment, we need to go in search of some Rub-A-Dub-Dub.
06:42Let's go, experimenters.
06:44Yeah!
06:48Off we go for another adventure.
06:50But what does Nina mean by Rub-A-Dub-Dub?
06:53Look, horses.
06:56Maybe they need some Rub-A-Dub-Dub look.
06:58No, you don't rub horses, Bod.
07:01You brush them.
07:03Sharpen your senses, neurons.
07:05I have a feeling that this will be fun.
07:20Hello, officers.
07:21Hello, Nina.
07:23Police men and women who ride horses are called mounted police.
07:27And there are lots of police horses here at these stables.
07:30But do you have any idea why I've brought you here?
07:33No, Nina.
07:34Well, if you follow me, I'll show you.
07:37This way.
07:39Oh, I just love it here.
07:42Those horses make lovely, neighing, snorty noises.
07:50These are the saddles and bridles the mounted police use in their work.
07:54And they're all made of shiny leather.
07:57What does it feel like?
08:01Smooth and soft.
08:03Yes, it is.
08:04It's lovely and soft.
08:05But look at this one.
08:14This saddle doesn't look quite so good, does it?
08:17And it feels different, too.
08:20It feels hard and rough.
08:22Yeah, that's because the leather is cracked and dry.
08:26It needs some looking after.
08:27And I have just the thing here.
08:30This is beeswax.
08:32It's a type of wax made by bees.
08:35It smells wonderful.
08:38The more wax we put in the leather, the softer and shinier it will become.
08:43And the wax will also protect the saddle from the rain.
08:46Because, as we discovered earlier, wax is waterproof.
08:50So come on, experimenters.
08:51It's time for some Rub-A-Dub-Dub.
09:06There, that's looking great.
09:08And it's feeling soft, too.
09:11Well done.
09:12But, Nina, what's this got to do with our ears?
09:16Well, Xanthi, though we can't see it, there is skin right inside our ears,
09:20which must be kept nice and soft, just like this leather saddle.
09:24And that's what our earwax does.
09:27It softens the skin inside our ears and stops it getting itchy and sore.
09:32But there's one more thing wax does to protect us.
09:36Let's go back to the lab for one final experiment.
09:39Yeah!
09:42OK, now here I have a big model of an ear.
09:46And this part is called the oracle.
09:49What-e-cle?
09:50Oracle bud.
09:51It's the part of the ear we can see.
09:54And the part inside is called the ear canal.
09:58And that's where the earwax is made.
10:01We're going to pretend that these cones are our ears.
10:04And you guys are going to put some of that sticky stuff
10:08all around the inside of that cone.
10:10Go for it!
10:22Oh, excellent!
10:25Nice and sticky.
10:27And this is like the wax inside our ears.
10:29What about another color nana?
10:31Ah, well, we're going to leave that one as it is.
10:34It's like an ear with no wax.
10:36Now, we have shakers here with glittery bits in
10:40that we're going to sprinkle onto the inside of the cones.
10:44Now, these are like bits of dust and dirt
10:47that can get into our ears from the ear around us.
10:51Remember, you should never put anything in your ear
10:54as it might damage it.
10:56That's right, Belle.
10:57We must never put anything into our real ears.
11:01OK, one, two, three, get shaking!
11:11OK, we can stop sprinkling.
11:14Let's have a look.
11:15So which one of our pretend ears
11:17do you think has the most glittery bits on the bottom?
11:20This one.
11:21The dry cone with no sticky stuff around the inside
11:25has definitely got more glittery bits down in the bottom.
11:28And why do you think that is?
11:30Because there was nothing stuffing going down.
11:33That's right.
11:34The sticky stuff on the other cone
11:37trapped all the glittery bits
11:39and stopped it from going down into the bottom.
11:42What happens to the dirty wax, Nina?
11:45Well, actually, our ears have a really clever way
11:48of moving old wax along with the trapped dirt
11:51out of our ears
11:53so they can be washed away in a bath or a shower.
12:01Your question was,
12:02what is earwax for?
12:04And I think we've answered it.
12:05Earwax is a shiny, sticky substance
12:08that is made inside our ears.
12:10It keeps the skin inside our ears
12:13soft and healthy
12:14and it also traps the dirt and dust
12:17that could be bad for our ears
12:18and helps our body to get rid of it.
12:20But remember, we must never put anything inside our ears
12:24because they don't like it.
12:26And thanks to our clever earwax,
12:28our brilliant ears are really good
12:30at looking after themselves.
12:32So I hope that's answered your question.
12:34Thanks, Nina.
12:36Bye.
12:37Bye.
12:41If you want to find out more about the science
12:44that's all around us,
12:45go to the Nina section on the CBeebies website.
12:48Have fun.
12:49Hearts beating.
12:50Lungs breathing.
12:52Fingers feeling.
12:53Mouth eating.
12:54And don't forget your brain.
12:56Brilliant bodies, brilliant bodies.
12:59Inside of our, our, our.
13:01Brilliant bodies, brilliant bodies.
13:03Come on, let's play loud above
13:06our handy hands and bendy knees.
13:09Stretch your backs and noises like a sneeze.
13:11We all have brilliant bodies.
13:14Brilliant, brilliant, brilliant bodies.
13:17Every part has a job to do.
13:20Even scabs and earwax too.
13:22We all have brilliant bodies.
13:25Brilliant bodies, brilliant bodies.
13:38It's been a marvellous day.
13:41We've discovered that wax can be hard and shiny
13:44and soft and squishy too.
13:47I really enjoyed myself today.
13:49The smell of all those polished leather saddles
13:52was brilliant.
13:53Ah, it's been such a great day, man.
13:57I just loved seeing all that shiny glitter.
14:00And remember, everyone's body is different
14:02but they're all brilliant.
14:03See you again soon.
14:04Bye.
14:05Bye.
14:08Nina and the new
14:10Brilliant bodies.
