0:00:02 > 0:00:06CBBC have sent these four magicians into your schools.
0:00:06 > 0:00:10They are some of the hottest magicians in the country.
0:00:10 > 0:00:13Our magicians went undercover
0:00:13 > 0:00:17and they pretended to be supply teachers.
0:00:17 > 0:00:21We had secret cameras all over your classrooms
0:00:21 > 0:00:24and watched while you had the most incredible lessons.
0:00:26 > 0:00:31Our magicians thrilled whole classes with their spectacular tricks.
0:00:31 > 0:00:33But did they come to your school?
0:00:33 > 0:00:35I never knew I were going to be on TV.
0:00:35 > 0:00:36Did they trick you?
0:00:36 > 0:00:37I'm just so freaked out.
0:00:37 > 0:00:39And did you shout...
0:00:42 > 0:00:43CHEERING
0:00:43 > 0:00:50Hello. It's me, Ian, and this is Help! My Supply Teacher Is Magic.
0:00:50 > 0:00:54We fooled hundreds of you guys by swapping regular teachers
0:00:54 > 0:00:58with magicians and we've been secretly filming the results
0:00:58 > 0:01:02with special cameras, which we've hidden in the classroom.
0:01:02 > 0:01:06We are cheekier than the cheekiest cheeky monkey and, believe you me,
0:01:06 > 0:01:11he is very cheeky. And, because we know magic is what you want,
0:01:11 > 0:01:14we're also showing you loads of other great tricks as well.
0:01:14 > 0:01:17Here's my amazing card flick.
0:01:17 > 0:01:18RECORD SCRATCHES
0:01:21 > 0:01:25It needs some work. Play some clips.
0:01:26 > 0:01:30Fergus is going undercover to cause mayhem in this class of year threes.
0:01:30 > 0:01:32Look, it's snowing in the classroom.
0:01:32 > 0:01:34FERGUS: It was amazing!
0:01:34 > 0:01:36But will they think he's the coolest teacher ever?
0:01:36 > 0:01:40We're going to teach you a magic trick so you can fool your friends.
0:01:40 > 0:01:43Grab a tape measure so you can join in.
0:01:43 > 0:01:46Plus you've been sending in clips of all your best magic tricks
0:01:46 > 0:01:50and later on, I'll be picking my five favourites.
0:01:50 > 0:01:52Will you be one of my Wannabe Wizards?
0:01:52 > 0:01:57Could you spot a magician pretending to be a supply teacher?
0:01:57 > 0:02:00Could you? Really?
0:02:00 > 0:02:04This is Fergus. He's cheeky and very sneaky.
0:02:04 > 0:02:06He's about to go undercover as a supply teacher.
0:02:06 > 0:02:09The hidden cameras are set. Will it be your school?
0:02:09 > 0:02:11Will it be your class? Let's find out.
0:02:11 > 0:02:13Here's a year three class.
0:02:13 > 0:02:15They don't know it yet,
0:02:15 > 0:02:19but Fergus is going to teach them about weather.
0:02:19 > 0:02:21I don't know "weather" they'll believe it or not!
0:02:21 > 0:02:25None of the class suspect there are cameras hidden in their classroom,
0:02:25 > 0:02:29or realise that Fergus is not a real teacher, but can he keep it up?
0:02:29 > 0:02:33Now, today's lesson is about precipitation.
0:02:33 > 0:02:34Precipi-what?
0:02:34 > 0:02:40That's a very posh word for something very simple. Precipitation is rain.
0:02:40 > 0:02:42Ah, now you're talking, Fergus.
0:02:42 > 0:02:45He's got their attention and the magic's on its way.
0:02:45 > 0:02:50Who can tell me what might happen if it's a bit colder? It becomes...
0:02:50 > 0:02:51- CHILDREN:- Snow.
0:02:51 > 0:02:58Very good. Now, snow is formed of something called snowflakes.
0:02:58 > 0:03:03Does anyone know what a snowflake looks like? Yeah?
0:03:03 > 0:03:07I'm going to show you with this piece of paper.
0:03:07 > 0:03:11Now, obviously it's not quite as big as this.
0:03:11 > 0:03:13Fergus is getting all creative.
0:03:13 > 0:03:16I can't wait to see what his snowflake looks like.
0:03:16 > 0:03:20So here's what my snowflake looks like.
0:03:20 > 0:03:22Ah.
0:03:22 > 0:03:24It looks a bit more like a doughnut, doesn't it?
0:03:24 > 0:03:27His art skills are not up to scratch,
0:03:27 > 0:03:31but the class have warmed to him and there's some cool magic coming up.
0:03:31 > 0:03:38Now, I'd like to tell you about my very first time I saw snow.
0:03:38 > 0:03:43I went to somewhere called Lapland.
0:03:43 > 0:03:49Lapland is where somebody lives that you might see at Christmas time.
0:03:49 > 0:03:52Someone I see at Christmas? Oh, my mum!
0:03:52 > 0:03:56- Do you know who I'm talking about? CHILDREN:- Santa!
0:03:56 > 0:03:57Ah, Santa, of course!
0:03:57 > 0:04:03When I arrived in Lapland, unfortunately, it was quite sunny,
0:04:03 > 0:04:07so all the snow had started to melt and go a bit slushy,
0:04:07 > 0:04:12so we begun a two-day trek into the very heart of Lapland.
0:04:12 > 0:04:16We were pulled on sleighs by huskies.
0:04:16 > 0:04:21As we drew closer to the heart of Lapland,
0:04:21 > 0:04:27it begun to get colder and colder.
0:04:28 > 0:04:33I could hear some faint music in the distance.
0:04:33 > 0:04:37That music sounded a little bit like this.
0:04:37 > 0:04:39CHRISTMAS MUSIC
0:04:39 > 0:04:45- And do you know what happened? - No, what happened? What happened?!
0:04:49 > 0:04:50What's he doing?
0:04:50 > 0:04:54And as we drew closer, amazingly, as it got colder and colder,
0:04:54 > 0:04:55it begun...
0:04:59 > 0:05:00..to snow.
0:05:00 > 0:05:03Whoa! Fergus is making it snow in the classroom!
0:05:03 > 0:05:08And it was amazing! And it carried on, look!
0:05:08 > 0:05:11An indoor snowstorm, that's amazing!
0:05:11 > 0:05:12And it carried on, didn't stop.
0:05:12 > 0:05:15Snowed and snowed and snowed.
0:05:15 > 0:05:18Look, the class are trying to grab the snow to make snowballs.
0:05:18 > 0:05:23And that was my first experience of Lapland.
0:05:24 > 0:05:25An astonishing trick.
0:05:25 > 0:05:29Fergus is now going to let them in on his little white lie.
0:05:29 > 0:05:35I haven't really been to Lapland.
0:05:35 > 0:05:37You lied! You lied!
0:05:37 > 0:05:40There's a very good reason why I told that little lie.
0:05:40 > 0:05:45Right now, this second, you're all being filmed
0:05:45 > 0:05:49on a new CBBC magic show
0:05:49 > 0:05:52and there's a camera in that box there and there's a camera
0:05:52 > 0:05:55in the box behind you and you're all going to be on TV!
0:05:55 > 0:05:57CHILDREN CHEER
0:06:00 > 0:06:01He did it!
0:06:01 > 0:06:05Fergus is a blizzard wizard and has totally fooled the class.
0:06:06 > 0:06:10First, Fergus made an... unconvincing snowflake.
0:06:10 > 0:06:11Looks like...
0:06:11 > 0:06:14I never knew that he was going to do that.
0:06:14 > 0:06:16I thought he was just going to teach us.
0:06:16 > 0:06:19Then he took the snowflake and turned it into a blizzard
0:06:19 > 0:06:21and it went down a storm.
0:06:21 > 0:06:24And he was like...and then it comes blasting out everywhere.
0:06:24 > 0:06:27Awesome. Brilliant.
0:06:27 > 0:06:28It was fantastic.
0:06:28 > 0:06:33Fergus pulled it off. The class had no idea he was a magician.
0:06:33 > 0:06:36Would you realise your supply teacher was magic?
0:06:41 > 0:06:45Later, Katherine will also be going undercover as a supply teacher.
0:06:45 > 0:06:49She's going to blow this class's mind with a mind-reading trick.
0:06:49 > 0:06:50Is this your class?
0:06:51 > 0:06:55This is John. He's going to teach you the secret
0:06:55 > 0:06:57behind a trick you can use at use at home.
0:07:01 > 0:07:04If you fancy yourself as a magician,
0:07:04 > 0:07:07here's a trick you can try on your mates.
0:07:07 > 0:07:10All you need is a tape measure. If you haven't got one already,
0:07:10 > 0:07:13go and get one now. Go on, hurry up.
0:07:13 > 0:07:16In the meantime, John will do these face exercises.
0:07:16 > 0:07:18You back? Ready? Good.
0:07:18 > 0:07:20Do you know how to work out someone's age
0:07:20 > 0:07:24by using only a tape measure? Can you work it out?
0:07:24 > 0:07:27Keep watching and you'll find out later in the show.
0:07:27 > 0:07:31But right now, we have something amazing for you.
0:07:31 > 0:07:34This is an interactive illusion.
0:07:34 > 0:07:37This is a trick that you can take part in at home, so, come on,
0:07:37 > 0:07:41get nice and close to the screen so you can follow all the action.
0:07:41 > 0:07:44You smell awful. Here's John.
0:07:48 > 0:07:52Were going to do a trick with the 12 animals from the Chinese calendar.
0:07:52 > 0:07:56They are a rooster, goat, dragon, ox,
0:07:56 > 0:08:02horse, rat, dog, snake, monkey, rabbit, tiger and a pig.
0:08:02 > 0:08:07You're going to put your finger here and move the animals like this.
0:08:09 > 0:08:15First, I want you to think of a secret number between 5 and 15.
0:08:16 > 0:08:18Have you got one? Good.
0:08:18 > 0:08:22Now, starting here, move your finger around the animals
0:08:22 > 0:08:25the same amount of times as your secret number,
0:08:25 > 0:08:30so if your secret number was six, you'd move six times, like this:
0:08:30 > 0:08:35One, two, three, four, five, six.
0:08:35 > 0:08:38So in this case, you'd be on the rabbit.
0:08:38 > 0:08:43Remember, starting here, move your finger the same amount of times
0:08:43 > 0:08:46equal to your secret number.
0:08:46 > 0:08:53Are you ready? Here we go. One, two, three, four...
0:08:53 > 0:08:56That's it, keep going till your secret number,
0:08:56 > 0:08:59and then stop and keep your finger there. Keep going.
0:09:01 > 0:09:05Oh, some of you have chosen quite a big number. OK, perfect.
0:09:05 > 0:09:09Stay right where you are. Let me take these away.
0:09:09 > 0:09:12Now, move in the other direction,
0:09:12 > 0:09:15the same number that you've just moved.
0:09:15 > 0:09:20That's moving this way the same amount equal to your secret number.
0:09:20 > 0:09:26Are you ready? One, two, three, four...
0:09:33 > 0:09:38OK. Good. Leave your finger where it is now.
0:09:38 > 0:09:41Now, I know you're not thinking of the goat, the rat,
0:09:41 > 0:09:45the snake or the rabbit, so I'll remove those.
0:09:46 > 0:09:52Now, you can move four more times either this way or this way.
0:09:52 > 0:09:57That's four times in either direction. Are you ready?
0:09:57 > 0:10:01One, two, three, four.
0:10:03 > 0:10:05Keep your finger there.
0:10:05 > 0:10:09Now, I know you're not thinking of the dragon, the ox or the pig.
0:10:09 > 0:10:11Keep your finger touching the screen
0:10:11 > 0:10:15and concentrate on the animal you are touching.
0:10:15 > 0:10:19You're thinking of the tiger.
0:10:19 > 0:10:20TIGER ROAR
0:10:20 > 0:10:22What was that?
0:10:23 > 0:10:26Do you know what calendars like to eat?
0:10:26 > 0:10:28Dates.
0:10:29 > 0:10:33Sorry, that joke's a bit dry. Every week, we have been bringing you
0:10:33 > 0:10:37the top five chart of new magicians on the block.
0:10:37 > 0:10:38I've got my comfy chair.
0:10:40 > 0:10:44I've got my trusty laptop and I've got a big bowl of grapes.
0:10:44 > 0:10:48Seedless, obviously. Hit it.
0:10:48 > 0:10:50We asked you to send in clips of yourself
0:10:50 > 0:10:52performing your best magic tricks.
0:10:52 > 0:10:56We received loads of clips from all over the country.
0:10:56 > 0:10:59Each week, I'll be choosing my five favourite wannabe wizards
0:10:59 > 0:11:01and showing them to you guys.
0:11:01 > 0:11:04Number five this time is Ed from Beaconsfield
0:11:04 > 0:11:08with his appearing ball trick. Oh, there it is in the right hand.
0:11:08 > 0:11:12That's it, put it in the pocket. There it is again.
0:11:12 > 0:11:18Get in that pocket. Oi! This time he's really going to get rid of it.
0:11:18 > 0:11:21Oh, would you believe it? But watch this. It's gone!
0:11:21 > 0:11:23Why didn't you do that in the first place?
0:11:23 > 0:11:26Appearing at number four, it's Connor from Birmingham,
0:11:26 > 0:11:30and he appears to be on carpet of giant playing cards.
0:11:30 > 0:11:35Would it be a magic carpet? So it's the ace of diamonds at the top,
0:11:35 > 0:11:38a quick flip, and it turns into the king of diamonds.
0:11:38 > 0:11:41That was a great trick for starters, but there's more.
0:11:42 > 0:11:47He's put the king of diamonds in the middle of the deck.
0:11:47 > 0:11:51But, pow, it's back at the top. Amazing! Keep your eye on that card.
0:11:51 > 0:11:53This bit will really shake you up.
0:11:53 > 0:11:55See what I mean? It's the king of spades.
0:11:55 > 0:11:57Great trick, but I dig this better.
0:11:57 > 0:11:59It's Calvin from Dudley with a real classic.
0:11:59 > 0:12:02He's got the cups-and-balls trick.
0:12:02 > 0:12:05I'll do it from my hand through the cups onto that.
0:12:05 > 0:12:07Three, two, one.
0:12:08 > 0:12:12Whoa! The ball went through the top two cups onto the bottom cup.
0:12:12 > 0:12:14Two, one, boof.
0:12:14 > 0:12:18Now two balls on the bottom cup. Do you think he can get his hat-trick?
0:12:18 > 0:12:19One last time.
0:12:21 > 0:12:23Three, two, one.
0:12:24 > 0:12:27Goal! Man of the match!
0:12:27 > 0:12:30But no match for Thomas from the Isle of Man
0:12:30 > 0:12:32with his never-say-die attitude.
0:12:32 > 0:12:35I went to the magic shop the other day
0:12:35 > 0:12:40and I asked the man if he had a red-and-white die and he said,
0:12:40 > 0:12:47"It's your lucky day. It comes inside this red-and-white die box."
0:12:47 > 0:12:50So that box has got to be bigger than the die, right?
0:12:50 > 0:12:52You know what's cool? When you're performing,
0:12:52 > 0:12:57you can put the box inside the die.
0:12:57 > 0:13:00Whoa! He put the big box into the smaller die.
0:13:00 > 0:13:01How is that possible?
0:13:01 > 0:13:03He said...
0:13:04 > 0:13:07"..Take the box out of the die..."
0:13:07 > 0:13:10This is a proper conundrum. Watch this.
0:13:10 > 0:13:15"..You open it up
0:13:15 > 0:13:18"and you put the die in and I said,
0:13:18 > 0:13:22"Well, that's really cool, but is there any other colours?"
0:13:22 > 0:13:26And he said, "Yes. I've just had this one shipped in from China."
0:13:26 > 0:13:28This is the best bit.
0:13:28 > 0:13:31"It's right here."
0:13:31 > 0:13:33Ta-dah!
0:13:33 > 0:13:36Who's my favourite, though? I'm not going to tell you yet,
0:13:36 > 0:13:39not before I put on my funny chart show voice.
0:13:39 > 0:13:43At number five, it's Ed's reappearing ball.
0:13:43 > 0:13:47On the carpet of cards, it's Connor at four.
0:13:47 > 0:13:50Calvin scores a hat-trick at three.
0:13:50 > 0:13:52Three, two, one.
0:13:52 > 0:13:57Thomas's impossible die rolls in at two, and he was nearly my favourite,
0:13:57 > 0:14:00but out of all of the clips of Wannabe Wizards,
0:14:00 > 0:14:02my top one this time was..
0:14:02 > 0:14:05Ruby from Rotherham with her jumping jacks.
0:14:05 > 0:14:08All right, so first I just need you to look at these cards.
0:14:08 > 0:14:13These are a random and ordinary pack of cards.
0:14:13 > 0:14:15But where are the jacks?
0:14:15 > 0:14:20You may or may not have noticed that I didn't put the jacks in there...
0:14:20 > 0:14:22I did notice, but only cos I saw it before.
0:14:22 > 0:14:27Four jacks. All right? So we can just pop them there.
0:14:27 > 0:14:30So she's put the four jacks back on the top of the deck.
0:14:30 > 0:14:36This trick is about me controlling these jacks to jump around the deck
0:14:36 > 0:14:40where I want them to, so this first jack, I'm just going to pop him
0:14:40 > 0:14:43to the bottom of the deck and if he does his job properly
0:14:43 > 0:14:45and with a bit of luck...
0:14:46 > 0:14:47..he jumps.
0:14:47 > 0:14:52Whoa! That jack jumped through the deck from the bottom to top.
0:14:52 > 0:14:57And if you do your job properly, under my control and my spell...
0:14:57 > 0:14:59Ouch!
0:14:59 > 0:15:01..he jumps to the bottom.
0:15:01 > 0:15:03Not a surprising jump with encouragement like that.
0:15:03 > 0:15:07This jack, I'm going to pop in the deck...
0:15:08 > 0:15:15..the wrong way, and if he can flip and turn round within seconds,
0:15:15 > 0:15:17then it must be magic.
0:15:17 > 0:15:18Got to love a catchphrase.
0:15:18 > 0:15:19Sure enough.
0:15:19 > 0:15:21That jack flipped and jumped to the top.
0:15:21 > 0:15:28This jack, I'm going to pop in somewhere in the middle of the deck,
0:15:28 > 0:15:30and if he does his job properly,
0:15:30 > 0:15:35I'll make him turn all the way round.
0:15:35 > 0:15:39So, Ruby made three jacks jump and the fourth's about to flip.
0:15:39 > 0:15:42Here it comes. Here it comes.
0:15:42 > 0:15:43In the deck.
0:15:43 > 0:15:44Wa-hay!
0:15:44 > 0:15:46Thanks for watching.
0:15:46 > 0:15:48The pleasure is all ours.
0:15:48 > 0:15:51Can't wait until next time for more Wannabe Wizards.
0:15:51 > 0:15:55Right now, I've got something pretty cool to show you.
0:15:55 > 0:15:59I'm going to make this £10 note go from one pocket to another.
0:15:59 > 0:16:02There's a £10 note. Just put it in there.
0:16:06 > 0:16:07Wow.

0:16:09 > 0:16:11Sorry, two seconds. Sorry.
0:16:11 > 0:16:13MOBILE PHONE RINGS
0:16:13 > 0:16:18Hello? Oh hey, sis. Yeah, that £20 I owe you?
0:16:18 > 0:16:20Yeah, I've got it right here.
0:16:21 > 0:16:27Oh. Sorry, I had to take this call. Here's what's coming up.
0:16:28 > 0:16:31Have you worked out the secret of John's challenge?
0:16:31 > 0:16:35If you haven't already got a tape measure, go and get it now. Hurry!
0:16:35 > 0:16:39And see what happens when Katherine goes undercover in another school.
0:16:39 > 0:16:40Could it be your class?
0:16:40 > 0:16:44Could your supply teacher be magic?
0:16:44 > 0:16:47Right now, though, classy magician Katherine
0:16:47 > 0:16:50is about to do an incredible trick at a museum.
0:16:53 > 0:16:55This is Tabs, Anabel and Georgina.
0:16:55 > 0:16:58They have no idea they're about to star in their own magic show.
0:16:58 > 0:17:03This card trick uses cards with different animals on the face,
0:17:03 > 0:17:06so if I show them all to you, we've got 52 different animals here,
0:17:06 > 0:17:13a pig, spider, buffalo, bear, all the way through,
0:17:13 > 0:17:16so what I'd like you to do, Anabel, is have a look through them
0:17:16 > 0:17:18and pick out any animal you like.
0:17:20 > 0:17:22The elephant.
0:17:22 > 0:17:23The elephant, good choice.
0:17:23 > 0:17:26So Annabel's chosen the elephant card.
0:17:26 > 0:17:28Any particular reason why you chose the elephant?
0:17:28 > 0:17:30No, not really.
0:17:30 > 0:17:33OK. What I'd like you to do is shuffle the deck for me.
0:17:33 > 0:17:35She's shuffled the cards.
0:17:35 > 0:17:42That's perfect. I'd just like you to cup your hands together. Great.
0:17:42 > 0:17:44Now I'm going to slide the elephant back in
0:17:44 > 0:17:46between the rest of the animals.
0:17:46 > 0:17:49Katherine's put the card back in the deck.
0:17:49 > 0:17:50I just want you to focus on the cards.
0:17:50 > 0:17:53- Now, how does an elephant move? - Stomps.
0:17:53 > 0:17:56He stomps about. He's quite heavy in his feet.
0:17:56 > 0:17:58Watch.
0:17:58 > 0:18:01Look at that! The cards are moving!
0:18:02 > 0:18:06One card moves. Do you want to take that out, Tabitha? Have a look.
0:18:06 > 0:18:07It's the elephant.
0:18:07 > 0:18:11Not only that, it's the card she picked! Lets get a rewind.
0:18:11 > 0:18:13Watch.
0:18:13 > 0:18:16The card magically came out of the pack.
0:18:16 > 0:18:18Incredible!
0:18:18 > 0:18:21Do you want to take that out, Tabitha? Have a look.
0:18:21 > 0:18:23It's the elephant.
0:18:23 > 0:18:25They can't believe it.
0:18:25 > 0:18:27The card just moved.
0:18:27 > 0:18:30The card moved and the elephant came.
0:18:30 > 0:18:32Really, really good, yeah.
0:18:32 > 0:18:35It's the moment you've all been waiting for -
0:18:35 > 0:18:37a chance to learn how to fool your friends.
0:18:37 > 0:18:40Me and John challenged you to work out someone's age
0:18:40 > 0:18:43by only using a tape measure.
0:18:43 > 0:18:45Have you worked it out? How many of you got it?
0:18:45 > 0:18:49Maybe you think it works by measuring your hands. Nah.
0:18:49 > 0:18:53Do you measure your feet? No! The circumference of your head?
0:18:53 > 0:18:55MAKES INCORRECT KLAXON SOUND
0:18:55 > 0:18:56Come on!
0:18:56 > 0:18:58You take the tape measure and pull it out
0:18:58 > 0:19:02to about the centimetre equivalent to the year we're in,
0:19:02 > 0:19:03then fold the tape measure over.
0:19:03 > 0:19:07So in 2012, you'd pull it out to 212 centimetres.
0:19:07 > 0:19:10That's 212 for 2012.
0:19:10 > 0:19:12Then lock the tape measure with the button
0:19:12 > 0:19:16and make sure the metal end is touching the tape measure.
0:19:16 > 0:19:18Then ask your friend what year they were born.
0:19:18 > 0:19:21OK, then, I was born in 1988.
0:19:21 > 0:19:24Run your finger along the tape to find the centimetre mark
0:19:24 > 0:19:27for the year I was born, so you put your finger
0:19:27 > 0:19:30on 188 centimetres for 1988.
0:19:30 > 0:19:34Go on, John, show them how that shows my age.
0:19:34 > 0:19:36John's keeping his finger on the year I was born
0:19:36 > 0:19:39and, on the opposite side of the folded tape measure,
0:19:39 > 0:19:44it's my age, 24. See the number 20 and the number four.
0:19:44 > 0:19:46Let's get a rewind.
0:19:46 > 0:19:50Folding a tape measure, you stretch the tape out to the year you're in,
0:19:50 > 0:19:53so 212 for 2012.
0:19:53 > 0:19:56Make sure the metal end is touching the tape measure.
0:19:56 > 0:19:59Pinch the tape measure at the year the person was born
0:19:59 > 0:20:01and on the other side will be their age.
0:20:04 > 0:20:06Did you get it? Are you amazing already?
0:20:06 > 0:20:10Now you've all got something to show off with in the playground.
0:20:11 > 0:20:15In Undercover Magic, we hide cameras in all sorts of places.
0:20:15 > 0:20:18Our magicians play tricks on members of the public
0:20:18 > 0:20:21who don't know they're being filmed.
0:20:21 > 0:20:23James is a super smart magician
0:20:23 > 0:20:26and he's about to go undercover in a shopping centre.
0:20:26 > 0:20:29This is Matthew. He doesn't know it yet,
0:20:29 > 0:20:30but he's been set up by his mum,
0:20:30 > 0:20:33and he's about to see an amazing trick.
0:20:33 > 0:20:36He has no idea what's about to happen. Here comes James now.
0:20:36 > 0:20:38Check him out. What's he up to?
0:20:38 > 0:20:40Sorry to bother you.
0:20:40 > 0:20:44I've just got a job interview in one of the shops down there.
0:20:44 > 0:20:46I need an opinion on a tie. Is it too much?
0:20:46 > 0:20:49- Pink tie, black shirt is a bit much. - It's a bit snazzy, isn't it?- Yeah.
0:20:49 > 0:20:51I'm worried about the jacket.
0:20:51 > 0:20:54The jacket might be a bit creased. Is it looking OK?
0:20:54 > 0:20:57Or maybe the blue tie with the stripy... Is that better?
0:20:57 > 0:20:59Hang on a minute. Something different!
0:20:59 > 0:21:02Is it his hair? Let's get a rewind.
0:21:02 > 0:21:04Oh, pink tie, black shirt.
0:21:04 > 0:21:06I'm a bit worried about the shirt.
0:21:06 > 0:21:09When he turns back, it's a stripy tie and blue shirt.
0:21:09 > 0:21:12Or maybe the blue tie with the stripy...
0:21:12 > 0:21:14That's incredible!
0:21:14 > 0:21:16I'm three hours late, so I've got to go. Thanks.
0:21:16 > 0:21:19Their faces say it all.
0:21:19 > 0:21:22I felt a bit confused and shocked at what just happened.
0:21:22 > 0:21:24Crazy.
0:21:24 > 0:21:28Now it's time for mind-bending Katherine
0:21:28 > 0:21:30to fool another unsuspecting class.
0:21:30 > 0:21:34She's going undercover as a supply teacher to do an incredible trick.
0:21:34 > 0:21:38Is this your school? Is it your class?
0:21:38 > 0:21:43And will this class realise that their supply teacher is magic?
0:21:43 > 0:21:46These year four pupils think they're coming in for science,
0:21:46 > 0:21:50but there's no formula to this lesson. It's totally experimental.
0:21:50 > 0:21:52The classroom's been rigged with hidden cameras
0:21:52 > 0:21:57and Katherine has got a mind-reading trick they'll never predict.
0:21:57 > 0:21:58Good morning, everybody.
0:21:58 > 0:22:01- CHILDREN:- Good morning.
0:22:01 > 0:22:03Now, we're going to be learning about mind reading.
0:22:03 > 0:22:06That's right, she said mind reading.
0:22:06 > 0:22:10That sounds exciting and I don't think they'll mind this lesson.
0:22:10 > 0:22:15This is a mind-reading device which my uncle has very kindly lent to me,
0:22:15 > 0:22:18because he works in a university as a professor,
0:22:18 > 0:22:22so if I put this mind-reading device on my head, I put it on to receive,
0:22:22 > 0:22:25I should be able to get some of your thoughts here in the room.
0:22:25 > 0:22:27You naughty little liar, Katherine.
0:22:27 > 0:22:30This story is just part of the trick.
0:22:30 > 0:22:33The aerial needs to be up as well.
0:22:33 > 0:22:35The aerial doesn't make any difference,
0:22:35 > 0:22:38cos there's no such thing as a mind-reading device, people!
0:22:41 > 0:22:44I've just had a thought come in, "She looks silly in that hat."
0:22:44 > 0:22:46That's what I was thinking!
0:22:46 > 0:22:50"How old is she?" is something else. "When's break time?" Right, OK.
0:22:50 > 0:22:54I'm getting a lot of thoughts, but I don't know who they're coming from
0:22:54 > 0:22:58unless somebody else is wearing the other device.
0:22:58 > 0:23:02Here we go. That means the magic's on the way.
0:23:02 > 0:23:06So, who would like to have a go at mind reading?
0:23:06 > 0:23:09Of course! Mind reading sounds great and they all believe it.
0:23:09 > 0:23:11- Yes, what's your name?- Tiago.
0:23:11 > 0:23:13Tiago? OK. Tiago, come on up here.
0:23:13 > 0:23:15Lucky Tiago.
0:23:15 > 0:23:20He has no idea he's going to play a massive part in this amazing trick.
0:23:20 > 0:23:24We're going to put the device on your head.
0:23:24 > 0:23:26Looking good, mate.
0:23:26 > 0:23:31Give him a set of these pictures. We've got here a flagpole,
0:23:31 > 0:23:37a chair, traffic lights, a bike, lots of different pictures,
0:23:37 > 0:23:41and I'm going to have an identical set myself, so you hold onto them.
0:23:41 > 0:23:46Now, I'm going to put yours here onto send and mine onto receive.
0:23:46 > 0:23:49She's turning those buttons, but they don't do anything.
0:23:49 > 0:23:52How on earth is Katherine going to read his mind?
0:23:52 > 0:23:55Now, what I'd like you to do is have a look through all the pictures
0:23:55 > 0:24:00and when you're thinking of one of them, let me know.
0:24:00 > 0:24:03He's chosen carefully and he's not letting Katherine see.
0:24:03 > 0:24:05Have you got one?
0:24:05 > 0:24:11OK, I want you to take that picture out and focus on it. That's perfect.
0:24:11 > 0:24:15He's got the tree, but Katherine has no idea.
0:24:15 > 0:24:18I have no idea what you're thinking of.
0:24:18 > 0:24:19I just said that!
0:24:19 > 0:24:22Now, Tiago, I'm going to attempt to read your mind,
0:24:22 > 0:24:25so close your eyes and visualise that image in your head very vividly,
0:24:25 > 0:24:28almost like a dream. Are you doing that for me?
0:24:28 > 0:24:30Tree, tree, tree, tree, tree.
0:24:33 > 0:24:37Right. Yep, I've definitely just had something come through here.
0:24:37 > 0:24:39I think I know what you're thinking of.
0:24:41 > 0:24:43I'm going to take the picture out...
0:24:45 > 0:24:50..and what I'd like you to do is pick up your picture out of this pile,
0:24:50 > 0:24:53hold it close to you so no-one can see it.
0:24:53 > 0:24:58I'm going to show everyone what I think you're thinking of.
0:25:00 > 0:25:01CHILDREN: Oh!
0:25:01 > 0:25:06Yay, she got it! But how?! My brain hurts, but it's not over yet.
0:25:06 > 0:25:08This was no fluke.
0:25:08 > 0:25:11This time were going to try something a bit different.
0:25:11 > 0:25:13We're going to get you to read my mind.
0:25:13 > 0:25:15Yeah, I'm speechless too.
0:25:15 > 0:25:21So, this time, you're on receive and I'm on send.
0:25:21 > 0:25:26Now, Tiago will read Katherine's mind. But how? He's not a magician.
0:25:26 > 0:25:29I'm going to have a look through all the different pictures.
0:25:35 > 0:25:39OK, so I've got a picture in my mind and I'm concentrating on it.
0:25:41 > 0:25:43And I'm sending it over to you now.
0:25:43 > 0:25:47What I want you to do is pick up the pictures,
0:25:47 > 0:25:50and when you think you know what I'm thinking of,
0:25:50 > 0:25:52I want you to take that picture out.
0:25:55 > 0:25:57I can't wait for this.
0:25:58 > 0:25:59Don't show me the pictures.
0:25:59 > 0:26:02I'm so confused. Will he read her mind?
0:26:02 > 0:26:06Take out the picture that you think I'm thinking of.
0:26:07 > 0:26:14OK, so I'm going to take out the picture I was thinking of.
0:26:14 > 0:26:19OK. I'd like you to turn over the picture...
0:26:19 > 0:26:23Has he done it? Has he done it? I'm going to hold my breath.
0:26:23 > 0:26:24I can't hold it any more!
0:26:24 > 0:26:25Whoa! He done it!
0:26:27 > 0:26:31Wow, isn't that amazing? Thank you very much.
0:26:31 > 0:26:33You can go and sit back down again.
0:26:33 > 0:26:35It's a mind-blowing trick,
0:26:35 > 0:26:39but it's time for Katherine to reveal her big secret.
0:26:39 > 0:26:41- Do you want to know something? CHILDREN:- Yes.
0:26:41 > 0:26:43That's not really a mind-reading device.
0:26:43 > 0:26:45- CHILDREN:- What?!
0:26:45 > 0:26:49That was a magic trick and I'm not a teacher, I'm a magician.
0:26:49 > 0:26:54And if you give a wave over there and a wave over there,
0:26:54 > 0:26:59you're being filmed right now to be on a new CBBC magic show.
0:26:59 > 0:27:00CHILDREN CHEER
0:27:00 > 0:27:01She did it!
0:27:01 > 0:27:06Katherine's brilliant mind-reading trick has totally fooled the class.
0:27:06 > 0:27:09First, Katherine read Tiago's mind.
0:27:12 > 0:27:15I didn't know how he knew what she was thinking.
0:27:15 > 0:27:19Then, incredibly, Tiago read Katherine's mind,
0:27:19 > 0:27:22which has got me totally bamboozled.
0:27:22 > 0:27:26I was really shocked when I found out this was a show.
0:27:26 > 0:27:31Katherine pulled it off. The class had no idea she was a magician.
0:27:31 > 0:27:35We totally got them and they loved it.
0:27:40 > 0:27:44If you're at school and you think something magical is stirring
0:27:44 > 0:27:47in the class, maybe you'll find yourself shouting,
0:27:47 > 0:27:51"Help, my supply teacher is magic!"
