0:00:16 > 0:00:20Hello and welcome once again to My Genius Idea. We're looking for
0:00:20 > 0:00:24the biggest, best, and brightest ideas from all of you.
0:00:24 > 0:00:30In My Genius Idea, we're looking for the next generation of inventors.
0:00:30 > 0:00:35We received ideas from all over the UK. Your Genius Ideas range from
0:00:35 > 0:00:39how to look after your pets, robots to help around the home,
0:00:39 > 0:00:42through to flying cars and eco-powered planes.
0:00:42 > 0:00:45Only 18 ideas made it to the heats...
0:00:47 > 0:00:49..and they'll now go head to head
0:00:49 > 0:00:52to see who will be crowned the overall winner.
0:00:52 > 0:00:54Our inventors will work with
0:00:54 > 0:00:57experts to help their inventions come to life,
0:00:57 > 0:01:01and go behind the scenes of some of our most successful organisations
0:01:01 > 0:01:05to give them the inspiration to progress their inventions further.
0:01:05 > 0:01:07I used it to inspire what I did.
0:01:07 > 0:01:11Deciding if they can progress in the competition will be down to
0:01:11 > 0:01:14expert inventor and judge, Tom Lawton.
0:01:16 > 0:01:19Tom has always had a passion for inventing.
0:01:20 > 0:01:23I love it. There are so many ideas all around us.
0:01:23 > 0:01:26Under everybody's nose is a solution to be solved
0:01:26 > 0:01:27or a problem to be addressed.
0:01:27 > 0:01:32Tom started inventing when he was ten, and by the time he was 21
0:01:32 > 0:01:34he developed his first product -
0:01:34 > 0:01:36the world's first recordable alarm clock.
0:01:36 > 0:01:40You always have ideas. And being an inventor is about actually
0:01:40 > 0:01:43seeing them through into something that's real.
0:01:43 > 0:01:45He's gone on to build a successful
0:01:45 > 0:01:49career as an inventor, winning international awards for his work.
0:01:49 > 0:01:51It's great doing a programme about young inventors
0:01:51 > 0:01:55because young inventors have a very fresh perception of the world.
0:01:55 > 0:01:58I hope to be inspired by some of these young minds.
0:01:59 > 0:02:01Hoping to impress Tom today are...
0:02:09 > 0:02:13And here they are. Welcome to the My Genius Idea nerve centre.
0:02:13 > 0:02:17- How are you all feeling? - Great.- You're feeling great?
0:02:17 > 0:02:20Lots of smiles, and feeling confident today?
0:02:20 > 0:02:22- Yeah.- No.- Yeah.- You're not...
0:02:22 > 0:02:25I'm dying to hear all about your ideas and inventions
0:02:25 > 0:02:29so I'm going to come to you, Stewart, first. Fill us in.
0:02:29 > 0:02:32Well, my invention stops you overfilling your bath,
0:02:32 > 0:02:36because of a sensor underneath this machine that goes over your bath.
0:02:38 > 0:02:41Cycling fanatic Stewart has come up with a revolutionary idea
0:02:41 > 0:02:45to ensure that baths will never overflow again, with his invention
0:02:45 > 0:02:47the wireless bath communication device.
0:02:47 > 0:02:53I thought of my idea when I was talking to my grandma
0:02:53 > 0:02:56and remembered that she overfills the bath,
0:02:56 > 0:03:02and so I decided that I was going to invent something to stop her
0:03:02 > 0:03:05overfilling the bath - or anyone overfilling the bath.
0:03:05 > 0:03:09Brilliant, I like that. OK, Pippa, I'm coming to you next.
0:03:09 > 0:03:12Big smile from Pippa. What's your idea?
0:03:12 > 0:03:16My idea is exercise boots, and erm...
0:03:16 > 0:03:20if you've been still for too long, they'll vibrate.
0:03:21 > 0:03:24Karate kid Pippa wants to take on couch potatoes and
0:03:24 > 0:03:26get them off the sofa.
0:03:26 > 0:03:29Her footwear exercise idea has built-in sensors,
0:03:29 > 0:03:32to detect if someone's been inactive for too long.
0:03:32 > 0:03:36If you haven't moved your feet
0:03:37 > 0:03:41in half an hour, they will vibrate and then you need to
0:03:41 > 0:03:44get up and do a series of exercises.
0:03:44 > 0:03:46Brilliant. Well, good luck, Pippa.
0:03:46 > 0:03:49Zoe, I'm going to come to you next. What's your idea?
0:03:49 > 0:03:53My idea is the tracker bag.
0:03:53 > 0:03:57High-flyer Zoe has come up with a boy's and girl's tracker bag
0:03:57 > 0:03:59with built-in satellite technology.
0:03:59 > 0:04:02It allows your parents to know where you are if you ever get lost.
0:04:02 > 0:04:06If you're late home from school one day,
0:04:06 > 0:04:11your parents can go on their phone or their laptop or whatever
0:04:11 > 0:04:16gadget they've got, and they can find out where you are.
0:04:16 > 0:04:22In the My Genius Idea HQ Pippa, Stewart, and Zoe
0:04:22 > 0:04:26will each have one hour to develop their idea with a top expert.
0:04:26 > 0:04:28Pippa's first out of the blocks.
0:04:28 > 0:04:32She's teamed up with sports technologist Dan Toon.
0:04:32 > 0:04:35So you're talking about a shoe that needs to vibrate
0:04:35 > 0:04:38when you've not done enough exercise, am I right?
0:04:38 > 0:04:40There are a number of ways of doing that.
0:04:40 > 0:04:42But it all depends upon
0:04:42 > 0:04:45how you think this idea might work. Have you thought about that?
0:04:45 > 0:04:49It might have a sensor in the bottom of the shoe.
0:04:49 > 0:04:50Yeah, it might have a sensor.
0:04:50 > 0:04:53There are different types of sensors that you can use.
0:04:53 > 0:04:57There are things like pressure sensors.
0:04:57 > 0:05:00That would be something that went in your shoe,
0:05:00 > 0:05:03and it would detect when you're wearing that shoe.
0:05:03 > 0:05:05You see here how this light activates?
0:05:05 > 0:05:10So that could say something like "Stop being lazy, do some exercise."
0:05:10 > 0:05:14Or it could make a noise, or it could have a pedometer built into it
0:05:14 > 0:05:17and every time you walk it counts your steps.
0:05:17 > 0:05:20So, Pippa's put in a gadget called a pedometer,
0:05:20 > 0:05:22which counts the steps you take.
0:05:22 > 0:05:25And Stewart's off to a flying start too,
0:05:25 > 0:05:28with his expert Kim Fisher, a products designer.
0:05:28 > 0:05:31I've come up with two or three areas where I think I can help.
0:05:31 > 0:05:33One is that
0:05:33 > 0:05:37sensing of the water level, here, and then communicating that sensing
0:05:37 > 0:05:42to whoever the person is who needs to know, and then to make sure
0:05:42 > 0:05:46that they actually hear it, that they actually hear the alarm.
0:05:46 > 0:05:50- What could go wrong?- Whenever you put electricity and water together,
0:05:50 > 0:05:55things go sparking, so waterproofing is very, very important in this.
0:05:55 > 0:05:59You should never put anything electrical in water,
0:05:59 > 0:06:01so Stewart needs to make sure his invention is safe.
0:06:03 > 0:06:07Meanwhile Zoe wants to know how big the tracking technology would be,
0:06:07 > 0:06:10with the help of her expert Tim Birkinshaw.
0:06:10 > 0:06:13Could we make it small enough for a smiley face?
0:06:13 > 0:06:15Oh, I suppose we could make the unit
0:06:15 > 0:06:19as small as something like that. Look at the size of that one.
0:06:19 > 0:06:23And then we could put that into a smiley face, anything that's really
0:06:23 > 0:06:27hides it and makes it look a bit more inconspicuous than a tracking unit.
0:06:27 > 0:06:30We need to really keep this as small as possible.
0:06:30 > 0:06:33What we don't want to do is put a great big box in there,
0:06:33 > 0:06:36fill the haversack and you won't have room for your sandwiches.
0:06:36 > 0:06:39So, a good first session for Zoe.
0:06:39 > 0:06:42She seems right on track with her idea.
0:06:42 > 0:06:45While Pippa is getting to grips with the best place
0:06:45 > 0:06:47to put the sensors in her exercise boots.
0:06:47 > 0:06:51Where would be best to have this sensor so he feels it?
0:06:51 > 0:06:53There.
0:06:53 > 0:06:56OK. And why do you think we'll have it there?
0:06:56 > 0:06:59Then you'll feel it on the bottom of your foot.
0:06:59 > 0:07:01So if he put his foot in here,
0:07:01 > 0:07:05his toes are here like that, aren't they - so he's going to feel it,
0:07:05 > 0:07:07it's going to vibrate right in here.
0:07:07 > 0:07:10So do you think a walking boot is the best option
0:07:10 > 0:07:12or do you think there are other options?
0:07:12 > 0:07:14Other options as well as walking boots.
0:07:14 > 0:07:18What types of options? Like maybe plimsolls or trainers, or...?
0:07:18 > 0:07:20Slippers.
0:07:20 > 0:07:23Slippers? You don't do any exercise in slippers, though -
0:07:23 > 0:07:25you just lounge around the house.
0:07:25 > 0:07:29That's good, because then that's how they'll vibrate, isn't it?
0:07:29 > 0:07:30Ah... OK.
0:07:30 > 0:07:34So it's reminding them that they haven't done enough exercise
0:07:34 > 0:07:37because they've been lazy round the house? Good one.
0:07:37 > 0:07:42And have you thought about any other sort of scenarios or times
0:07:42 > 0:07:46when you might need this type of sensor? Like for instance...
0:07:46 > 0:07:50Erm, when you're on planes and on trains.
0:07:50 > 0:07:53Very good. And why do you think you would need it then?
0:07:53 > 0:07:55Because you're still for ages.
0:07:55 > 0:07:58That's exactly right.
0:07:58 > 0:08:01Pippa's invention could help long-distance travellers
0:08:01 > 0:08:04as they too need to take regular exercise.
0:08:04 > 0:08:07And Stewart is experimenting with sensor technology,
0:08:07 > 0:08:10looking how to sound an alarm when the bath is full.
0:08:10 > 0:08:12Pull it out... Put it in.
0:08:12 > 0:08:16That's it. You can see on the indicator,
0:08:16 > 0:08:17the water has touched the sensor.
0:08:17 > 0:08:20What happens then, with that?
0:08:20 > 0:08:21A wireless signal is sent to
0:08:21 > 0:08:27a wireless device that clips onto you anywhere in the house.
0:08:27 > 0:08:29Right. And what happens then?
0:08:29 > 0:08:31- And then this'll happen. - BEEPING
0:08:31 > 0:08:36It'll start beeping, or you might make your own and go...
0:08:36 > 0:08:38- VOICE:- You've forgotten your bath.
0:08:38 > 0:08:41And how do you turn the sensor off from bleeping?
0:08:41 > 0:08:45Well, to stop it bleeping, you have to go up and get the bath.
0:08:45 > 0:08:48And how are these signals being sent round?
0:08:48 > 0:08:53They're being sent wirelessly through radio and things like that.
0:08:53 > 0:08:58So as Stewart finds out the best way to send his full bath message alert,
0:08:58 > 0:09:02Zoe's investigating how the receiver may work for her tracker bag idea.
0:09:02 > 0:09:05One thing we haven't looked at is how are they going to see you,
0:09:05 > 0:09:08what's somebody going to look at to see where you are?
0:09:08 > 0:09:12We need to be looking really at some sort of software that we could look
0:09:12 > 0:09:15on a computer, so your mum and dad can go and have a look
0:09:15 > 0:09:17and see exactly where you are.
0:09:17 > 0:09:20You could maybe customise your face,
0:09:20 > 0:09:28and you could make, like, a person that looks like you.
0:09:28 > 0:09:30So when Mum and Dad look at a computer,
0:09:30 > 0:09:33instead of just seeing a dot of where you are,
0:09:33 > 0:09:36they're actually going to see your smiling face.
0:09:36 > 0:09:39I think that's a very good idea and that can easily be incorporated,
0:09:39 > 0:09:42and it isn't going to have any effect on the size of our unit.
0:09:42 > 0:09:46Having investigated the technologies to make her idea work,
0:09:46 > 0:09:49Zoe puts the finishing touches to the look of the bag.
0:09:49 > 0:09:53With only 20 minutes left, I'm off to see how the budding inventors
0:09:53 > 0:09:56are coming along. It's Pippa first with her exercise boots.
0:09:56 > 0:09:58Having a car boot sale here(?)
0:09:58 > 0:10:02I'll give you 50p for that. What's going on?
0:10:02 > 0:10:05We've been brainstorming your idea, Pip, haven't we really?
0:10:05 > 0:10:08We've been thinking about this idea of this exercise shoe
0:10:08 > 0:10:10and different sensors.
0:10:10 > 0:10:13So as well as everyday use, we're talking about using these
0:10:13 > 0:10:15on aeroplanes. How would it work?
0:10:15 > 0:10:19It would remind them to get up and walk around on planes
0:10:19 > 0:10:23so they don't sit down all the time.
0:10:23 > 0:10:27- It's not very healthy if you're just sat still for a long time.- Yeah.
0:10:27 > 0:10:29- So it's got a medical use as well. - It has.
0:10:29 > 0:10:31Good luck. I'll leave you to it.
0:10:33 > 0:10:35Stewart has sussed out all the components
0:10:35 > 0:10:38he'll need to make his invention work.
0:10:38 > 0:10:41It looks quite animated over here. Talk us through it.
0:10:41 > 0:10:44This is the new type of sensor that's made to go in water
0:10:44 > 0:10:46even though it's electric.
0:10:46 > 0:10:49It tests how much water there is.
0:10:49 > 0:10:53What's important is to do it wirelessly,
0:10:53 > 0:10:56and if we have one of these it will connect to...
0:10:56 > 0:11:00- well, this is a sort of thing like a handset...- Yeah.
0:11:00 > 0:11:02..and it'll set off when
0:11:02 > 0:11:04this is attached to that.
0:11:04 > 0:11:05BEEPING
0:11:07 > 0:11:08What happens then is...
0:11:08 > 0:11:10- VOICE:- Hello, it's bath time.
0:11:10 > 0:11:13Ha-ha. That's absolutely brilliant.
0:11:13 > 0:11:16So what you're saying is that when your bath's overflowing,
0:11:16 > 0:11:19your bath will in effect call you?
0:11:19 > 0:11:20Yeah.
0:11:21 > 0:11:25And that just leaves Zoe to catch up with.
0:11:25 > 0:11:27I want to know about your design.
0:11:27 > 0:11:30You can get a boy's schoolbag and a girl's schoolbag,
0:11:30 > 0:11:35and on the girl's schoolbag there would be love hearts and flowers,
0:11:35 > 0:11:39and on the boy's bag there would be footballs and skulls.
0:11:39 > 0:11:42It's all well and good having
0:11:42 > 0:11:45a tracking device in a bag, but what about the person on the other end -
0:11:45 > 0:11:48how are THEY going to know where you are?
0:11:48 > 0:11:50This is the software we'd be using
0:11:50 > 0:11:52when we're tracking Zoe around,
0:11:52 > 0:11:55so we can actually see a little person on a map on there.
0:11:55 > 0:11:56Happy with your progress?
0:11:56 > 0:11:59- Yeah. - Brilliant. I'll leave you to it.
0:11:59 > 0:12:00Brilliant.
0:12:01 > 0:12:05So what does expert inventor and judge Tom make of the ideas so far?
0:12:05 > 0:12:09I'm impressed, as ever, and the quality of the originality of
0:12:09 > 0:12:14the ideas sings through, doesn't it? That's what invention's all about,
0:12:14 > 0:12:16it's about thinking in a different way.
0:12:16 > 0:12:19I'm particularly impressed that a couple of them are thinking about
0:12:19 > 0:12:22applications for other people, not just themselves.
0:12:22 > 0:12:25It's wonderful to think of other people's problems
0:12:25 > 0:12:26and how you would solve them,
0:12:26 > 0:12:29rather than thinking central to yourself.
0:12:29 > 0:12:33Well, Tom, I don't want to keep you any longer. Have another look.
0:12:34 > 0:12:37Tom will be judging all their ideas later on.
0:12:37 > 0:12:41He'll want to know how well Pippa, Stewart and Zoe have understood the
0:12:41 > 0:12:46technology behind their ideas, and how well they can sell them to him.
0:12:46 > 0:12:48It looks fascinating...
0:12:48 > 0:12:52Only one of today's inventors can win a place in the semifinals.
0:12:52 > 0:12:53To make the most of your time
0:12:53 > 0:12:56it's essential to learn as much as you can.
0:12:57 > 0:13:00There's still loads left to be done to make these ideas work
0:13:00 > 0:13:04and as the old saying goes, a good idea never goes out of fashion.
0:13:04 > 0:13:07So we thought it would be cool to send this lot off
0:13:07 > 0:13:08to meet a world-famous designer
0:13:08 > 0:13:11to see how the world of fashion comes up with new ideas.
0:13:15 > 0:13:19Wale Adeyemi is one of the UK's most successful fashion designers
0:13:19 > 0:13:21and a celebrity stylist.
0:13:21 > 0:13:27Famous clients include Sugababes, Estelle, Example, and Alicia Keys.
0:13:27 > 0:13:31Describing his style as somewhere between the kerb and the boutique,
0:13:31 > 0:13:34Wale gets his inspiration from the streets of London.
0:13:34 > 0:13:37It would be great for the kids if I can get across to them
0:13:37 > 0:13:40how you don't really have to look so far to be inspired,
0:13:40 > 0:13:43you just have to appreciate those things that are around you.
0:13:45 > 0:13:49I'm excited because and going to meet a fashion designer
0:13:49 > 0:13:54who designs lots of clothes for lots of famous people.
0:13:54 > 0:13:57I hope to get some more inspiration
0:13:57 > 0:14:01for my invention and hopefully help me win this competition.
0:14:04 > 0:14:08Today I'm going to show you how we work and how we're inspired
0:14:08 > 0:14:09by all the amazing things that are around us.
0:14:09 > 0:14:12We're going out with a camera and I'll show you how I get ideas
0:14:12 > 0:14:15and the things I see along the street which inspire me.
0:14:19 > 0:14:22Basically all this artwork on the walls here and all these taggers,
0:14:22 > 0:14:24this is called graffiti.
0:14:24 > 0:14:27My first collection, this inspired what I did.
0:14:27 > 0:14:30- What's the main featured colour here that we can see?- Green.- Yes.
0:14:30 > 0:14:33- What other colours can you see that you like?- Purple.
0:14:33 > 0:14:35- White.- White, purple.
0:14:35 > 0:14:37What does this piece say to you?
0:14:37 > 0:14:39It says pizzazz.
0:14:39 > 0:14:41Pizzazz, oh, that's a good word.
0:14:41 > 0:14:46- Why pizzazz?- Colourful, and it's like the guy is coming out of the wall.
0:14:48 > 0:14:52There's loads of different sunglasses, shapes and colours.
0:14:52 > 0:14:56If you squint your eyes, it's a really nice coloured pattern.
0:14:59 > 0:15:03I'm going to give you the camera, and I want you to go around
0:15:03 > 0:15:06and take some shots and then we'll go back to my studio,
0:15:06 > 0:15:09get it printed onto a T-shirt, and put it onto a model.
0:15:09 > 0:15:13When you're thinking of great ideas, you've got to know who'll use them.
0:15:13 > 0:15:16In fashion, you need to know who'll wear your clothes
0:15:16 > 0:15:21- before you design them.- I like all the different patterns.
0:15:23 > 0:15:27I took this photo because the sunglasses look hypnotising.
0:15:30 > 0:15:34White and black are two great colours to mix together.
0:15:35 > 0:15:40There's plenty to see, so back at base it's time to share their photos
0:15:40 > 0:15:42and the inspiration behind them with Wale.
0:15:42 > 0:15:45I think they've taken some great photos, I'm quite impressed.
0:15:45 > 0:15:49Hopefully they've kept in mind the person they're designing for.
0:15:49 > 0:15:52I like the pictures, I'm very impressed.
0:15:52 > 0:15:55- Did you enjoy doing it?- Yes.
0:15:55 > 0:15:59That's a great shot. What did you have in mind?
0:15:59 > 0:16:01The colours blend together
0:16:01 > 0:16:05and the yin and yang are black and white so it gives it more.
0:16:05 > 0:16:07That's good, that's great.
0:16:07 > 0:16:09And then...
0:16:09 > 0:16:11this one, which is great.
0:16:11 > 0:16:16What was your idea behind that and what kind of person did you think?
0:16:16 > 0:16:19I was thinking about the street person
0:16:19 > 0:16:22that likes to stand out from the crowd.
0:16:22 > 0:16:26Oh, good, OK. And then the last one,
0:16:26 > 0:16:29this one. So what was your idea behind that,
0:16:29 > 0:16:32- who was the person you thought of? - My little sister.
0:16:32 > 0:16:33Your little sister? Cool,
0:16:33 > 0:16:36and it's quite simple, that would be nice on a T-shirt.
0:16:36 > 0:16:38Give yourself a clap, then.
0:16:41 > 0:16:44We're going to get them printed and we'll get a model to wear them.
0:16:44 > 0:16:47The key message I want you to leave with
0:16:47 > 0:16:50is always remember who you're designing for,
0:16:50 > 0:16:54always, always, always. And always be inspired by the outside world.
0:16:54 > 0:16:59I think Wale's right about being inspired by the world
0:16:59 > 0:17:03because it's just beautiful to look at.
0:17:06 > 0:17:10He said to think about who you're doing it for,
0:17:10 > 0:17:14and I think that's going to help me to make my invention better.
0:17:14 > 0:17:16We're back in the My Genius Idea HQ
0:17:16 > 0:17:19and with only ten minutes of the development session left,
0:17:19 > 0:17:24Pippa, Stewart, and Zoe will see if their ideas can actually work.
0:17:24 > 0:17:26The pressure is on.
0:17:26 > 0:17:28We've been talking about the different sensors.
0:17:28 > 0:17:32I'd like to show you some science behind it, OK? Follow me.
0:17:32 > 0:17:35Pippa's been looking into the sensors
0:17:35 > 0:17:36that could make her exercise boots work.
0:17:36 > 0:17:41She'll see the technology which could bring her invention to life.
0:17:41 > 0:17:44So if you could stand on these sensors,
0:17:44 > 0:17:49that's it, and if you look on the screen, you can see your pressure.
0:17:49 > 0:17:51Move backwards and forwards,
0:17:51 > 0:17:53just sway your body backwards and forwards,
0:17:53 > 0:17:56your pressure is picked up on-screen.
0:17:56 > 0:17:58What would happen if you stayed still?
0:17:58 > 0:18:01We need these people to be moving, that's the whole idea.
0:18:01 > 0:18:03We talked about it vibrating,
0:18:03 > 0:18:07or flashing, or making a noise. Which one do you prefer?
0:18:07 > 0:18:08Making a noise.
0:18:08 > 0:18:11So like a loud beep? Or playing some music?
0:18:11 > 0:18:13Something like that.
0:18:13 > 0:18:18Stewart has really thought about who'll use his invention
0:18:18 > 0:18:21as he goes through some preparation for his pitch to Tom.
0:18:21 > 0:18:25A wireless signal will be sent to a wireless device
0:18:25 > 0:18:28that clips onto you anywhere in the house,
0:18:28 > 0:18:30and then this will happen.
0:18:30 > 0:18:35- It will start beeping.- Why do we have this colour display here?
0:18:35 > 0:18:37The flashing one is for people who are deaf,
0:18:37 > 0:18:39who can't hear the beeping.
0:18:39 > 0:18:41Right.
0:18:41 > 0:18:44And the sound is for people who are blind,
0:18:44 > 0:18:48and the vibrating is for people who are both blind and deaf.
0:18:48 > 0:18:51- But they may need a bit more help. - Yes.
0:18:53 > 0:18:55Zoe has decided on the design for her invention,
0:18:55 > 0:18:58but will she be able to find the right technology
0:18:58 > 0:19:00to make her tracker bag become a reality?
0:19:00 > 0:19:04If she is successful, it could put her ahead in the competition.
0:19:04 > 0:19:08Each of these pinpoints was actually tracking me
0:19:08 > 0:19:13to the studio this morning, so if that was you walking around school,
0:19:13 > 0:19:17we actually see where you'd been, which classrooms you'd been to,
0:19:17 > 0:19:21and we could've tracked absolutely everything you were doing.
0:19:21 > 0:19:24Any other uses do you think we could put this technology to?
0:19:24 > 0:19:29People who are walking their dog or they're elderly,
0:19:29 > 0:19:31in case they get lost,
0:19:31 > 0:19:35and mountain climbers, in case they get lost up the hills.
0:19:35 > 0:19:38Time's up and Pippa has decided which sensors to use
0:19:38 > 0:19:42on her exercise boots, Stewart has made his invention waterproof
0:19:42 > 0:19:45and worked out how he might alert different users,
0:19:45 > 0:19:50and Zoe has found other uses for her tracker bag invention.
0:19:50 > 0:19:54But who will impress Tom to win the place in the semifinals?
0:19:58 > 0:20:02All three of our budding inventors now have to pitch to Tom.
0:20:02 > 0:20:04First up to see him is Zoe.
0:20:04 > 0:20:07Make your way to the presentation den.
0:20:07 > 0:20:11Tom's waiting for you there. Good luck.
0:20:11 > 0:20:15Will Zoe be able to impress Tom with her tracker bag idea,
0:20:15 > 0:20:19and can she persuade him to put her through to the next round?
0:20:19 > 0:20:21- Hi, Zoe, how are you?- Fine.- Good.
0:20:21 > 0:20:24I'm looking forward to learning about your tracker bag.
0:20:24 > 0:20:26Can you explain the idea to me?
0:20:26 > 0:20:29The tracker bag is all about safety
0:20:29 > 0:20:35because the little chips,
0:20:35 > 0:20:39they are a GPS tracking device.
0:20:39 > 0:20:42If you were on the other side of the world,
0:20:42 > 0:20:46that would tell your mum and dad, or whoever is looking for you,
0:20:46 > 0:20:47where you are.
0:20:47 > 0:20:50I guess it's not just for schoolchildren,
0:20:50 > 0:20:52it could work for anybody?
0:20:52 > 0:20:56It's for mountain climbers in case they get lost
0:20:56 > 0:20:59- up in the mountains or the hills.- Yes, OK.
0:20:59 > 0:21:05And it's for elderly people, in case they get lost,
0:21:05 > 0:21:09and it's for adults as well.
0:21:09 > 0:21:13OK, I love your designs, the graphic that you've done here.
0:21:13 > 0:21:16They look brilliantly colourful and well designed
0:21:16 > 0:21:18for people of perhaps your age.
0:21:18 > 0:21:19So it could be designed
0:21:19 > 0:21:22in a different way for different people?
0:21:22 > 0:21:23Yes.
0:21:23 > 0:21:27Have you learned much from the time that you've spent with the expert?
0:21:27 > 0:21:31He taught me about GPS and how far it can go around the world.
0:21:31 > 0:21:33Well, I'm very impressed.
0:21:33 > 0:21:36It seems like you've thought your idea through,
0:21:36 > 0:21:40so thank you very much. I think that was a really good presentation.
0:21:43 > 0:21:45I think it went really well.
0:21:45 > 0:21:50I spoke really clearly and Tom was smiling at me.
0:21:50 > 0:21:54Next to see Tom is Stewart. Has he done enough development
0:21:54 > 0:21:57on his wireless bath communication device
0:21:57 > 0:22:01to convince Tom that his idea has the most potential?
0:22:01 > 0:22:04I'm very intrigued to learn about your bath idea.
0:22:04 > 0:22:05Can you explain it to me?
0:22:05 > 0:22:09It's a device that is capable of stopping you
0:22:09 > 0:22:12- from overfilling the bath.- OK.
0:22:12 > 0:22:18When the water rises and touches the sensor underneath the box
0:22:18 > 0:22:21that slides up and down,
0:22:21 > 0:22:23it will send out a wireless signal
0:22:23 > 0:22:26to the WBCD, which is clipped to you.
0:22:26 > 0:22:30It will then beep, flash, and vibrate
0:22:30 > 0:22:34all at once to say your bath is done.
0:22:34 > 0:22:38It's interesting idea, that's for sure. What's your inspiration?
0:22:38 > 0:22:44Well, I based it on people with memory problems,
0:22:44 > 0:22:47the disabled, the elderly.
0:22:47 > 0:22:50And people with teenagers who forget the bath.
0:22:50 > 0:22:54- And do you know of any of those? - Many.
0:22:54 > 0:22:56So it's a problem amongst teenagers
0:22:56 > 0:22:59as well as those people who are forgetful.
0:22:59 > 0:23:02Is there anything else you'd like to tell me?
0:23:02 > 0:23:06- It's environmentally friendly. - In what way?
0:23:06 > 0:23:11Because if you don't overfill the bath, you're using less water,
0:23:11 > 0:23:13less fuel to heat the hot water.
0:23:13 > 0:23:18- Yes, OK.- And you're not wasting water by letting it flow down the drain.
0:23:18 > 0:23:20In the same way, that saves money.
0:23:20 > 0:23:23I think you really seem to know your invention inside out,
0:23:23 > 0:23:26and you've taken on a huge amount of knowledge
0:23:26 > 0:23:27from your expert.
0:23:27 > 0:23:30So thank you very much for presenting to me
0:23:30 > 0:23:33- because I thought it was brilliant. - Thank you.
0:23:34 > 0:23:37With his pitch over, all Stewart can do is wait.
0:23:37 > 0:23:39Finally, it's time for Pippa to pitch to Tom.
0:23:39 > 0:23:44Tom's not looking for a finished idea today, he's looking
0:23:44 > 0:23:47for an idea that has the most potential.
0:23:47 > 0:23:50He'll judge them on the technologies they've mastered
0:23:50 > 0:23:54and how well they can explain their idea to him.
0:23:54 > 0:23:58Hello, Pippa. Can you explain what exercise boots are to me, please?
0:23:58 > 0:24:05Well, they keep you healthy and they have a pedometer which is connected
0:24:05 > 0:24:10to a pressure sensor in the back of the shoe.
0:24:10 > 0:24:12That's connected to this,
0:24:12 > 0:24:18which will give you a message according to how many steps
0:24:18 > 0:24:25you've done. They're good for people on an aeroplane or train,
0:24:25 > 0:24:28injured or ill people, elderly people
0:24:28 > 0:24:31and office workers because they keep still.
0:24:31 > 0:24:36If you don't exercise when it says you need to,
0:24:36 > 0:24:40- it will make a really annoying alarm.- Right, OK.
0:24:40 > 0:24:43So other people would know that you're lazy?
0:24:43 > 0:24:47And you mentioned earlier that perhaps people who...
0:24:47 > 0:24:51did you say had injuries or physiotherapy needs?
0:24:51 > 0:24:56People who are injured or ill, because if you're ill
0:24:56 > 0:24:58you lie in bed and you don't move around.
0:24:58 > 0:25:01It's a great idea and you've done a brilliant presentation,
0:25:01 > 0:25:04so thank you very much, Pippa.
0:25:07 > 0:25:11So for two budding inventors, the competition will be over shortly,
0:25:11 > 0:25:15but who has won a place in the next round?
0:25:15 > 0:25:18Will it be Zoe's idea for a tracker bag which can find you
0:25:18 > 0:25:21wherever you are?
0:25:21 > 0:25:23Stewart's wireless bath communication device
0:25:23 > 0:25:26which stops you over-filling your bath?
0:25:26 > 0:25:31Or will it be Pippa's exercise boots that vibrate to get you moving?
0:25:31 > 0:25:35Three great ideas there, Tom, but what were the presentations like?
0:25:35 > 0:25:39Really strong. Each of them are starting to become experts
0:25:39 > 0:25:42in their own inventions, which is what it's about.
0:25:42 > 0:25:44They presented those ideas well?
0:25:44 > 0:25:45They presented them brilliantly.
0:25:45 > 0:25:48This has been the closest of all of the heats.
0:25:48 > 0:25:50Wow, so a difficult decision, then?
0:25:50 > 0:25:53Very difficult, but I've made my decision.
0:25:53 > 0:25:55If you'd like to take a seat, Tom,
0:25:55 > 0:25:57it's time to get the young inventors in.
0:25:57 > 0:26:02It's crunch time. They've all spent time developing their ideas
0:26:02 > 0:26:03and have pitched them to Tom,
0:26:03 > 0:26:07but who has won that last place in the semifinals?
0:26:07 > 0:26:09Pippa, Stewart, Zoe,
0:26:09 > 0:26:12it's decision time. How are you feeling?
0:26:12 > 0:26:16- Nervous.- Tom has come to a decision. It's time to find out
0:26:16 > 0:26:18who is going through to the next round.
0:26:18 > 0:26:21- Tom, it's over to you. - I'm impressed as ever.
0:26:21 > 0:26:23This one has been really close to call.
0:26:23 > 0:26:27Zoe, you had a great understanding of the technology,
0:26:27 > 0:26:31but I'm concerned that the idea relies on having
0:26:31 > 0:26:33the bag with you all the time.
0:26:33 > 0:26:37Stewart, your idea's developed really well since the beginning
0:26:37 > 0:26:40and you've taken on a lot from what your expert said,
0:26:40 > 0:26:42but I am concerned the technology might be difficult
0:26:42 > 0:26:45for the user to use.
0:26:45 > 0:26:48Pippa, you've got a fabulous idea and I find it inspiring
0:26:48 > 0:26:50that you want to make everybody active,
0:26:50 > 0:26:53but I do wonder, because those people are lazy,
0:26:53 > 0:26:57they just might kick those shoes off and it won't work.
0:26:57 > 0:26:59But I have come to a conclusion
0:26:59 > 0:27:03and the young inventor who I am going to send through
0:27:03 > 0:27:06to the semifinal of My Genius Idea...
0:27:11 > 0:27:15..is Stewart.
0:27:15 > 0:27:17Congratulations, Stewart.
0:27:17 > 0:27:20So Stewart wins with his invention,
0:27:20 > 0:27:22the wireless bath communication device
0:27:22 > 0:27:25and he's still in with a chance of winning My Genius Idea.
0:27:25 > 0:27:28It was tough, but now we've chosen all of our semifinalists.
0:27:28 > 0:27:31Next time it's the big one, it's the semifinals
0:27:31 > 0:27:33and it's going to be exciting.
0:27:33 > 0:27:37Don't forget what's at stake, a place in the final. Until next time.
