1:20:05 > 1:20:08# If you've got a question and you don't know where to go
1:20:08 > 1:20:11# Ask Nina for some help Cos she's got a science show
1:20:11 > 1:20:14# She makes sense of senses While helping her fans
1:20:14 > 1:20:17# By doing her experiments with potions and with bangs
1:20:17 > 1:20:19- # Touch your tongue - Tongue!

1:20:53 > 1:20:55# Oh, yeah! #
1:20:57 > 1:21:00There you are, Prickles. Hello, there.
1:21:00 > 1:21:03I was just watering my cactus plant.
1:21:03 > 1:21:06I named it Prickles because it's got lots of sharp spines.
1:21:06 > 1:21:11That's why I'm wearing these thick gloves, to protect my fingers.
1:21:11 > 1:21:13BEEPING
1:21:13 > 1:21:18I hear a beep, I see a flash. I wonder what they're going to ask.
1:21:19 > 1:21:23- ALL: Hi, Nina!- Hi, guys!
1:21:23 > 1:21:26We've got a question for you.
1:21:26 > 1:21:28How do our fingertips feel things?
1:21:28 > 1:21:33Great question. "How do our fingertips feel things?"
1:21:33 > 1:21:35I have a feeling I can help you find the answer.
1:21:35 > 1:21:39Why don't you come down to my lab and we'll experiment to investigate?
1:21:39 > 1:21:44- ALL: See you soon, Nina. Bye! - Bye!
1:21:44 > 1:21:48I'm going to need some help to answer this, and I know who to ask.
1:21:48 > 1:21:52OK, neurons. Time to get to work.
1:21:52 > 1:21:54MUSIC
1:22:07 > 1:22:10ALL: Neurons at the ready, Nina.
1:22:10 > 1:22:14OK, today's question is, "How do our fingertips feel things?"
1:22:14 > 1:22:16Which neuron do you think will be most useful
1:22:16 > 1:22:18in helping us find the answer?
1:22:18 > 1:22:21ALL: Me! Me! Me! Me!
1:22:21 > 1:22:23Will it be fabulous Felix?
1:22:23 > 1:22:27I can help so very much if you need the sense of touch.
1:22:27 > 1:22:29Will it be beautiful Belle?
1:22:29 > 1:22:33I send messages to brain from ear. If there's a sound, I'll help you hear.
1:22:33 > 1:22:38- Will it be lovely Luke? - For looking and seeing, day or night,
1:22:38 > 1:22:40I'll help you with your sense of sight.
1:22:40 > 1:22:42Will it be awesome Ollie?
1:22:42 > 1:22:45If it's pongy or whiffy but you can't tell
1:22:45 > 1:22:49- my messages help your sense of smell. - Or will it be baby Bud?
1:22:49 > 1:22:54Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!
1:22:57 > 1:22:58- Oh! - It's Felix!
1:22:58 > 1:23:01CHEERING
1:23:01 > 1:23:05ALL: Go Felix! Go, Felix! Go, Felix! Go, Felix!
1:23:08 > 1:23:13Marvellous. A little touch can mean so much, Nina.
1:23:13 > 1:23:17Today's question is, "How do our fingertips feel things?"
1:23:17 > 1:23:22We feel using our sense of touch so touch neuron, Felix, will help us.
1:23:22 > 1:23:25I need to get the lab ready before the experimenters arrive.
1:23:28 > 1:23:31'Toni likes the swings, Mya likes tomato soup
1:23:31 > 1:23:33'and Emilija loves apples.
1:23:33 > 1:23:36'They want to know how fingertips feel things, so today,
1:23:36 > 1:23:40'for one day only, Toni, Mya and Emilija become the experimenters!'
1:23:42 > 1:23:45- Hi, guys! - ALL: Hi, Nina.
1:23:45 > 1:23:50Welcome to my science lab. Come in. Come on down.
1:23:50 > 1:23:54You asked, "How do our fingertips feel things?"
1:23:54 > 1:23:56A brilliant question. Why do you want to know?
1:23:56 > 1:24:01Because I like cuddling my toys because they're soft and fluffy.
1:24:01 > 1:24:04But we don't know how our fingertips feel things.
1:24:04 > 1:24:07Being able to touch and feel with our fingertips
1:24:07 > 1:24:11helps us do lots of important things and helps us stay safe.
1:24:11 > 1:24:15We should definitely investigate to find out more.
1:24:15 > 1:24:18For our first experiment, we're going to use our senses.
1:24:18 > 1:24:23ALL: Whoop-whoo! A senses experiment! We're ready, Nina.
1:24:23 > 1:24:25For this experiment, I want you to try
1:24:25 > 1:24:30and identify three mystery objects using only your sense of touch.
1:24:30 > 1:24:33This should be lots of touchy-feely fun!
1:24:33 > 1:24:40So put your hand into your box. How does that feel?
1:24:41 > 1:24:44It feels squidgy. I think it's glue.
1:24:44 > 1:24:47- You think it could be glue? - Gooey.
1:24:47 > 1:24:49Let's see.
1:24:51 > 1:24:56Oh, you were very close. It's slime. Ha-ha!
1:24:56 > 1:25:02Well done, Emilija. OK, Toni. It's your turn.
1:25:02 > 1:25:04Reach your hand into your box and tell us
1:25:04 > 1:25:08what it feels like and then try and guess what you think it is.
1:25:08 > 1:25:10It feels cold.
1:25:10 > 1:25:14- Is it wet or dry? - It is wet.
1:25:14 > 1:25:17What do you think it might be?
1:25:17 > 1:25:21- An ice-lolly. - Let's have a look.
1:25:22 > 1:25:24NINA GIGGLES
1:25:24 > 1:25:29Yey, you're right! Well done, it's an ice-lolly.
1:25:29 > 1:25:32It's a bit wet because it's starting to melt.
1:25:34 > 1:25:39OK, Mya, it's your turn. Get feeling with those fingers.
1:25:40 > 1:25:42What does it feel like?
1:25:42 > 1:25:46- It's hot. - What do you think it might be?
1:25:46 > 1:25:49It might be a hot water bottle.
1:25:49 > 1:25:53Well, let's see. Hand out.
1:25:54 > 1:25:58You're right, it's a hot water bottle. Well done.
1:25:58 > 1:26:01Oh, and it's lovely and warm.
1:26:01 > 1:26:05I'm glad it doesn't feel too hot, Nina. Hot things can hurt us.
1:26:05 > 1:26:06That's right, Felix.
1:26:06 > 1:26:09If we do touch something that can hurt us,
1:26:09 > 1:26:13like my prickly cactus, here...
1:26:13 > 1:26:15- Oh! - Ouch!
1:26:15 > 1:26:18Our fingertips feel the danger and send a message to our brain.
1:26:18 > 1:26:22Our brain makes us pull our hand away really quickly.
1:26:22 > 1:26:25So our sense of touch doesn't just help us work out
1:26:25 > 1:26:28what things are, it also helps us to stay safe
1:26:28 > 1:26:31and teaches us to be more careful around things that might be
1:26:31 > 1:26:34hot or prickly in the future.
1:26:34 > 1:26:39We still need to find out how our fingertips feel things.
1:26:39 > 1:26:41I know a fun place where we might find the answer.
1:26:41 > 1:26:43ALL: Yey!
1:26:46 > 1:26:49Hmm, where do you think we're going today?
1:26:49 > 1:26:53- Nina said it was somewhere fun. - Maybe it's a puppet show.
1:26:53 > 1:26:55Puppet shows are fun.
1:26:55 > 1:26:58Maybe it's a finger puppet show, Bud.
1:26:58 > 1:27:03We're here, but I can't see any puppets.
1:27:03 > 1:27:06So experimenters, we've come to a sports centre where children
1:27:06 > 1:27:10can play on this very special floor. Would you like a go?
1:27:10 > 1:27:12ALL: Yes, please!
1:27:12 > 1:27:15OK. We'll all put a foot on the special floor.
1:27:15 > 1:27:16MOOING
1:27:16 > 1:27:19Look at those lights. That's so cool.
1:27:19 > 1:27:22Making those noises sounds like fun.
1:27:22 > 1:27:25It is fun, Belle, but it can also help us
1:27:25 > 1:27:29understand how our fingertips feel things.
1:27:29 > 1:27:33This floor has lots of special things in it called sensors.
1:27:33 > 1:27:37When you touch the floor, the sensors can feel it
1:27:37 > 1:27:39so they light up and make a noise.
1:27:39 > 1:27:41The skin on our fingertips
1:27:41 > 1:27:46and the skin everywhere else on our body has special sensors in it, too.
1:27:46 > 1:27:48We call these nerves.
1:27:48 > 1:27:53- I know all about nerves, Nina. - I know you do, Felix.
1:27:53 > 1:27:56When something touches our skin, the nerves feel it.
1:27:56 > 1:27:59A bit like the sensors in this floor.
1:27:59 > 1:28:03- Will we try it out some more? - ALL: Yes!
1:28:03 > 1:28:06ANIMAL NOISES
1:28:14 > 1:28:16Let's see if our hands work on the floor, too.
1:28:16 > 1:28:20- ANIMAL NOISES - Yes.
1:28:23 > 1:28:27Do you notice anything about the lights and noises, experimenters?
1:28:27 > 1:28:30They're all different.
1:28:30 > 1:28:33There's different colours and different noises.
1:28:33 > 1:28:36That's right. The sensors in this floor aren't all the same.
1:28:36 > 1:28:39Neither are the touch nerves on our skin.
1:28:39 > 1:28:42Come and have a look at this.
1:28:42 > 1:28:45So we've discovered that when we touch something
1:28:45 > 1:28:49with our fingertips, or any part of our body,
1:28:49 > 1:28:55special nerves in our skin sense it, but our nerves aren't all the same.
1:28:55 > 1:28:58This picture shows the nerves in our skin.
1:28:58 > 1:29:01Different nerves sense different kinds of feelings.
1:29:01 > 1:29:06Some of them can feel if something's hot or cold,
1:29:06 > 1:29:10and other nerves can feel when things are hard or soft.
1:29:10 > 1:29:15Other nerves can feel things like tickles. Hee-hee-hee!
1:29:15 > 1:29:18There's more we can know about fingertips and nerves.
1:29:18 > 1:29:21Let's go to the lab for a final experiment.
1:29:21 > 1:29:22ALL: Yeah!
1:29:23 > 1:29:27For this challenge, I need you all to cover your eyes
1:29:27 > 1:29:33so that you can only use your sense of touch, so put on your blindfolds.
1:29:33 > 1:29:35Their sense of sight won't help them now.
1:29:35 > 1:29:39You each have a different mystery something to feel,
1:29:39 > 1:29:44but this time, I want you to use your elbows and feet to feel first.
1:29:44 > 1:29:49Elbows at the ready, girls! Get feeling!
1:29:49 > 1:29:51JAZZY MUSIC
1:29:58 > 1:30:00OK, elbows out.
1:30:00 > 1:30:06- Mya, can you describe what you felt? - Hard and... Bumpy.
1:30:06 > 1:30:08Hard and bumpy.
1:30:08 > 1:30:11I felt it wet.
1:30:11 > 1:30:16- It was wet. Very good. Toni? - It was fluffy.
1:30:16 > 1:30:21Very good, girls. I think it's time to feel with our feet.
1:30:21 > 1:30:24I like it when Nina walks barefoot in warm sand.
1:30:24 > 1:30:26Ah, what a lovely feeling.
1:30:26 > 1:30:29OK, feet down and feel.
1:30:29 > 1:30:31JAZZY MUSIC
1:30:38 > 1:30:41Emilija, what does it feel like to you?
1:30:41 > 1:30:44It feels wet.
1:30:45 > 1:30:50- Toni? - It feels tickly and soft.
1:30:50 > 1:30:52- Mya? - Smooth.
1:30:52 > 1:30:56OK, I think you'd better use your fingers.
1:30:56 > 1:30:57Oh, goody!
1:30:57 > 1:31:00- Can you feel what they are now? - Stones.
1:31:00 > 1:31:02Stones! Toni?
1:31:02 > 1:31:04Feathers.
1:31:04 > 1:31:07- Emilija? - Sponge?
1:31:07 > 1:31:11A sponge. Why don't you take your blindfolds off and have a look?
1:31:14 > 1:31:15Ah! Stones!
1:31:15 > 1:31:18You've got a sponge with water in.
1:31:18 > 1:31:20Well done, experimenters.
1:31:20 > 1:31:23That experiment has shown us
1:31:23 > 1:31:27that it's a lot easier to feel things and work out what they are
1:31:27 > 1:31:30with our fingertips than with our elbows or feet.
1:31:30 > 1:31:35That's because some parts of our bodies have more nerves than others.
1:31:35 > 1:31:38Our fingertips have more different nerves than other parts
1:31:38 > 1:31:42of our body because we need to use them to feel things all the time.
1:31:42 > 1:31:45That's why they're so brilliant and figuring things out.
1:31:50 > 1:31:54So, your question was, "How do our fingertips feel things?"
1:31:54 > 1:31:56I think we've answered it.
1:31:56 > 1:31:59We discovered that skin on our fingertips, and everywhere else
1:31:59 > 1:32:05on our bodies, contains special sensors called nerves.
1:32:05 > 1:32:07Nerves send messages to our brain.
1:32:07 > 1:32:09Different nerves sense different things
1:32:09 > 1:32:13like hot or cold, wet or dry, or if something is sore to touch.
1:32:13 > 1:32:17Some parts of our bodies have more nerves than others,
1:32:17 > 1:32:20and our fingertips have got the most of all.
1:32:20 > 1:32:23They're packed with all sorts of nerves.
1:32:23 > 1:32:26This makes them brilliant at feeling all sorts of things.
1:32:26 > 1:32:29I hope that's answered your question.
1:32:29 > 1:32:34- ALL: Thanks, Nina. Bye! - Bye!
1:32:36 > 1:32:40Want to find out more about the science all around us?
1:32:40 > 1:32:44Go to the Nina section on the CBeebies website. Have fun!
1:32:44 > 1:32:49- Hearts beating.- Lungs breathing. - Fingers feeling.- Mouths eating.

1:33:41 > 1:33:43I've had a brilliant day.
1:33:43 > 1:33:48That special floor made funny noises when it was touched.
1:33:48 > 1:33:51Ah, it's been such a great day, man.
1:33:51 > 1:33:55Seeing the experimenters trying to feel things with their feet.
