0:01:08 > 0:01:09Oh, hi!
0:01:09 > 0:01:12ALL: Hi, Nina.
0:01:12 > 0:01:14I've got a new demonstration.
0:01:14 > 0:01:17It's all to do with static electricity.
0:01:17 > 0:01:19You might have used it before -
0:01:19 > 0:01:22when you rub a balloon on your sleeve,
0:01:22 > 0:01:25to see if it will stick to the wall.
0:01:25 > 0:01:27Hey hey!
0:01:27 > 0:01:29The balloon hangs there.
0:01:29 > 0:01:32It's static electricity holding it up.
0:01:32 > 0:01:35It doesn't just stick things together.
0:01:35 > 0:01:37It can make them fly apart.
0:01:37 > 0:01:39This machine makes static electricity.
0:01:39 > 0:01:42I'll turn it on so you see how it works.
0:01:42 > 0:01:45MACHINE WHIRRS
0:01:45 > 0:01:48- ELECTRICITY CRACKLES - It's brilliant!
0:01:48 > 0:01:50- ELECTRICITY CRACKLES - Ha-ha!
0:01:50 > 0:01:57I have a little plate here full of little pieces of paper.
0:01:57 > 0:02:00I'm going to sit it on top of our machine.
0:02:00 > 0:02:02I'm going to turn it back on.
0:02:02 > 0:02:05Keep an eye on the pieces of paper.
0:02:05 > 0:02:08MACHINE WHIRRS
0:02:08 > 0:02:10NINA CHUCKLES
0:02:10 > 0:02:12Fantastic!
0:02:12 > 0:02:14Just as I'd hoped.
0:02:14 > 0:02:18Because the pieces of paper are quite small and light,
0:02:18 > 0:02:22the static electricity makes them fly everywhere.
0:02:22 > 0:02:24The lighter something is,
0:02:24 > 0:02:27the easier it can be carried through the air.
0:02:27 > 0:02:32Really tiny things like dust can be carried even further.
0:02:34 > 0:02:37Thank you very much, everyone.
0:02:37 > 0:02:39- Have a lovely day. - ALL: Bye.
0:02:39 > 0:02:41BLEEPING
0:02:41 > 0:02:45I hear a beep, I see a flash. I wonder what they're going to ask.
0:02:51 > 0:02:55Hi, Nina. My name's Denham and I've got a question.
0:02:55 > 0:02:56Sure, Denham.
0:02:56 > 0:03:00How can I find out where the bad smell comes from?
0:03:00 > 0:03:02Oh, that's an interesting question.
0:03:02 > 0:03:04Bad smells can get everywhere.
0:03:04 > 0:03:06I'm on my way.
0:03:06 > 0:03:08- Bye, Nina.- Bye.
0:03:09 > 0:03:14We need help to answer this one. I know just who to ask.
0:03:14 > 0:03:16OK, Neurons, time to get to work.
0:03:32 > 0:03:35ALL: Neurons at the ready, Nina.
0:03:35 > 0:03:37OK, the question from Denham is,
0:03:37 > 0:03:41how can I find where a bad smell comes from.
0:03:41 > 0:03:45Which Neuron will be most useful in helping us find the answer?
0:03:45 > 0:03:48ALL: Me!
0:03:48 > 0:03:51Will it be fabulous Felix?
0:03:51 > 0:03:54I can help so very much If you need the sense of touch.
0:03:54 > 0:03:57Will it be beautiful Belle?
0:03:57 > 0:03:59I send messages, brain to ear
0:03:59 > 0:04:01If there's a sound I'll help you hear.
0:04:01 > 0:04:03Will it be lovely Luke?
0:04:03 > 0:04:05For lookin' and seein', day or night
0:04:05 > 0:04:08I'll help you with your sense of sight.
0:04:08 > 0:04:10Will it be awesome Ollie?
0:04:10 > 0:04:13If it's pongy or whiffy But you can't tell
0:04:13 > 0:04:15My messages help your sense of smell.
0:04:15 > 0:04:19- Or will it be baby Bud? - Sour, salty, bitter or sweet
0:04:19 > 0:04:22I'm your taste buddy whenever you eat.
0:04:25 > 0:04:27It's Ollie.
0:04:27 > 0:04:29ALL: Go, Ollie!
0:04:29 > 0:04:31Go, Ollie! Go, Ollie!
0:04:31 > 0:04:34Go, Ollie! Go, Ollie! Go, Ollie!
0:04:34 > 0:04:36Go, Ollie!
0:04:36 > 0:04:40Standing by to smell and tell, Nina.
0:04:40 > 0:04:42We're doing lots of smelling,
0:04:42 > 0:04:45so we need Ollie to help sniff out this stink.
0:04:48 > 0:04:50OK, then.
0:04:50 > 0:04:51Let's go.
0:05:09 > 0:05:13'Meet Denham, his sister Ariana and their mum and dad,
0:05:13 > 0:05:16'a regular family from Port Glasgow.
0:05:16 > 0:05:18'For one day only, they are...
0:05:18 > 0:05:21'the Experimentals!'
0:05:25 > 0:05:27- Hi, everyone! - ALL: Hi, Nina.
0:05:27 > 0:05:29SHE SNIFFS
0:05:29 > 0:05:31Oh!
0:05:31 > 0:05:35Oh! Oh, hi there. You must be Denham.
0:05:35 > 0:05:39You wanted to know how to find where a bad smell comes from.
0:05:39 > 0:05:41- Can you smell it?- I can!
0:05:41 > 0:05:44I'm glad you can - I thought it was just me.
0:05:44 > 0:05:47Now I know why you asked that question.
0:05:47 > 0:05:52Oh, there's a real stink around here, isn't there?
0:05:52 > 0:05:55But we'll solve this problem scientifically.
0:05:55 > 0:05:59I think it's time for our first experiment.
0:06:01 > 0:06:02Ready, Ollie?
0:06:04 > 0:06:06It's my big moment. Standing by.
0:06:06 > 0:06:09Ready to send lots of messages.
0:06:09 > 0:06:12So, where can we smell the smell?
0:06:12 > 0:06:15- Over the house.- Yeah, it IS all over the house.
0:06:15 > 0:06:21So, my idea is, why don't we just try getting out of the house?
0:06:21 > 0:06:22What do you think?
0:06:22 > 0:06:25- ALL: Yeah. - Well, let's go!
0:06:25 > 0:06:26NINA SNIFFS
0:06:26 > 0:06:29How does that smell now?
0:06:29 > 0:06:30I can't smell it.
0:06:30 > 0:06:34- We just need to stay out here. - We can't stay out here.
0:06:34 > 0:06:38- We can't stay out here.- Oh! - Because it might rain.
0:06:38 > 0:06:41That's a very good point.
0:06:46 > 0:06:48That would be terrible.
0:06:48 > 0:06:51Let's try something else. Back inside, come on.
0:06:51 > 0:06:55- SHE SNIFFS - We're back inside with the smell.
0:06:55 > 0:06:57How do we smell things?
0:06:57 > 0:07:00With our nose.
0:07:00 > 0:07:02If we block our noses,
0:07:02 > 0:07:05we shouldn't be able to smell the smell.
0:07:05 > 0:07:08Let's try holding our noses.
0:07:08 > 0:07:10Don't pinch too hard.
0:07:10 > 0:07:12You'll hurt your nose.
0:07:12 > 0:07:16But don't pinch too softly or you'll still smell the stink.
0:07:16 > 0:07:20- NASALLY:- Can you smell anything? - No.- But we sound funny.
0:07:20 > 0:07:22Yeah, we do, don't we?!
0:07:22 > 0:07:24That gives us a clue.
0:07:24 > 0:07:27The smell must be in the air all around us.
0:07:27 > 0:07:31So maybe if we don't breathe in, we won't smell the smell.
0:07:31 > 0:07:34Why don't we try holding our breath?
0:07:34 > 0:07:36SHE INHALES DEEPLY
0:07:36 > 0:07:40When you breathe in, you're sucking air into your lungs.
0:07:40 > 0:07:44To get there, it needs to go through your mouth or nose.
0:07:44 > 0:07:49And when the air passes through your nose, you can smell smells.
0:07:49 > 0:07:53So, if you don't breathe in, you won't notice the smell.
0:07:53 > 0:07:55Can you smell anything?
0:07:55 > 0:07:56No.
0:07:56 > 0:07:59But we can't do this all the time.
0:07:59 > 0:08:00SHE BREATHES OUT
0:08:00 > 0:08:04Maybe we could try to disguise the smell.
0:08:04 > 0:08:08- What could we smell that would be nicer?- BOTH: Flowers!
0:08:08 > 0:08:12That's a lovely idea! Could you find some flowers for me?
0:08:12 > 0:08:13Brilliant!
0:08:15 > 0:08:17Oh, we've found some flowers.
0:08:17 > 0:08:20Let's put these under our noses and smell.
0:08:20 > 0:08:22And how do they smell?
0:08:22 > 0:08:26- Strong.- Strong, that's right.
0:08:26 > 0:08:28Now, I'll bring them over here,
0:08:28 > 0:08:31and try and sniff them from there.
0:08:31 > 0:08:34- How do they smell?- Not strong.
0:08:34 > 0:08:38They're not so strong, are they? So, smells are stronger
0:08:38 > 0:08:42when you're near where the smell's coming from.
0:08:42 > 0:08:45Now, if we move round the house
0:08:45 > 0:08:47and find where the smell is strongest,
0:08:47 > 0:08:50we'll find where the smell is coming from.
0:08:52 > 0:08:55Right, time for a quick quiz.
0:08:55 > 0:08:57Who thinks they know most about smells?
0:08:57 > 0:09:01ALL: Me! Me! Me!
0:09:01 > 0:09:04Which of the following makes the smelliest stink?
0:09:04 > 0:09:09Is it number one - a pair of old socks? Oh!
0:09:09 > 0:09:15Or is it number two - oh! A stinky burp?
0:09:15 > 0:09:17Or is it number three...
0:09:17 > 0:09:22A sweaty armpit?
0:09:24 > 0:09:29Or is it number four - seaweed? Oh!
0:09:29 > 0:09:34Or number five... Oh! Rotten eggs.
0:09:34 > 0:09:38It's make your mind up time, Neurons.
0:09:38 > 0:09:41Which one smells the strongest?
0:09:41 > 0:09:46I know the answer, yes. Number two would be my guess.
0:09:46 > 0:09:51Now, listen up, I'll tell you more, I'm sure the answer's number four.
0:09:51 > 0:09:56Which answer's right? Let me see, I'm going to go for number three.
0:09:56 > 0:10:01I think I've sniffed the answer out. It's number five, no doubt.
0:10:01 > 0:10:06Number one looks tasty to me! So, Nina, who will the winner be?
0:10:06 > 0:10:11The winner is... Ollie! The answer was number five.
0:10:11 > 0:10:15Rotten eggs, and boy, do these eggs pong!
0:10:15 > 0:10:19And that's because the stink of rotten eggs comes from a chemical
0:10:19 > 0:10:22which mixes with the air really easily.
0:10:22 > 0:10:26So your nose picks it up as a stronger smell. Ugh!
0:10:26 > 0:10:30Time to be getting back to Denham and his sister.
0:10:30 > 0:10:33They're trying to sniff out that bad smell.
0:10:35 > 0:10:37SHE SNIFFS
0:10:44 > 0:10:47SHE CONTINUES SNIFFING
0:10:49 > 0:10:52BLEEPING
0:10:52 > 0:10:56- SHE SNIFFS - Ugh! Oh! We're in your mum and dad's room,
0:10:56 > 0:10:59and this is where the smell is strongest.
0:10:59 > 0:11:02That means this is where the smell is.
0:11:02 > 0:11:05Oh! I think the smell is coming from this bag!
0:11:05 > 0:11:08- Oh!- Pooh!- Horrible, isn't it?
0:11:08 > 0:11:11Right, I'm opening the bag, very brave!
0:11:11 > 0:11:13Oh! Oh! Oh! Oh! Oh!
0:11:13 > 0:11:17Oh! These are stinky, whose are these trainers?
0:11:17 > 0:11:19BOTH: My dad's shoes.
0:11:19 > 0:11:23Well done, Ollie! You found the stink.
0:11:23 > 0:11:27Yes, but the pong is worse than ever cos we're so close to it!
0:11:27 > 0:11:31Oh! Ugh! Ugh!
0:11:33 > 0:11:38We managed to find where the smell was coming from
0:11:38 > 0:11:43and it was Dad's old trainers! Oh! Ha ha!
0:11:43 > 0:11:45Now, we need to get rid of them.
0:11:45 > 0:11:48I'm gonna put them in this bin bag.
0:11:48 > 0:11:52I am glad to see the back of those stinky shoes!
0:11:52 > 0:11:54I don't think anyone will miss them!
0:11:54 > 0:11:59- How does that smell now, Denham? - Fine.- Far better!
0:11:59 > 0:12:03We've managed to solve your problem. You wanted to know
0:12:03 > 0:12:07how can you find where a bad smell comes from? We found out
0:12:07 > 0:12:10there are smells all around us,
0:12:10 > 0:12:14and we can smell them through our noses when we breathe in
0:12:14 > 0:12:18and smells are stronger when you're close to where the smell is.
0:12:18 > 0:12:21In this case, your dad's trainers!
0:12:21 > 0:12:24I'm glad I could help answer your question.
0:12:24 > 0:12:26I have to go back to my work now.
0:12:26 > 0:12:29I'll take the stinky trainers with me.
0:12:29 > 0:12:31Bye-bye, everyone!
0:12:31 > 0:12:33ALL: Bye!
0:12:45 > 0:12:48# It's been a busy, busy day
0:12:48 > 0:12:51# Questions answered, experiments done
0:12:51 > 0:12:54# We've all used our senses in so many ways
0:12:54 > 0:12:57# Tell me, Neurons, what have you done today? #
0:12:57 > 0:13:00I definitely worked the hardest today.
0:13:00 > 0:13:05Sniffing those trainers wore me out, the smell was so strong!
0:13:05 > 0:13:07Yeah, I was pretty busy.
0:13:07 > 0:13:10I loved looking at those flowers.
0:13:10 > 0:13:12They were really colourful!
0:13:12 > 0:13:15I was working hard too, you know.
0:13:15 > 0:13:19I had lots of messages to carry when everyone was holding their noses.
0:13:19 > 0:13:24- I feel filthy thinking about it! - There were loads of sounds for me!
0:13:24 > 0:13:28Everyone sounded different with their noses pinched.
0:13:28 > 0:13:29We do sound funny!
0:13:29 > 0:13:33Wowee! I've been a busy baby Bud!
0:13:33 > 0:13:39Those trainers were so stinky you could almost taste them! Hee!
0:13:39 > 0:13:42# Nina and the Neurons
0:13:42 > 0:13:45# Nina and the Neurons
0:13:46 > 0:13:47# Oh oh-oh-oh... #
0:13:47 > 0:13:52That was great fun. I hope you've had a sensational time too. Bye!
