0:35:50 > 0:35:57.
0:36:02 > 0:36:05CBBC have sent these four magicians into your schools.
0:36:06 > 0:36:09They are some of the hottest magicians in the country.
0:36:11 > 0:36:13And when they're not in your classrooms,
0:36:13 > 0:36:15they're out in public, fooling families.
0:36:22 > 0:36:25But right now, here's a trick you can try on your mates.
0:36:27 > 0:36:28You need a pen
0:36:28 > 0:36:31and a piece of paper with the Roman numerals for nine written on it.
0:36:31 > 0:36:34That's an I and an X.
0:36:34 > 0:36:37If you haven't got them already, go and get them now. Go on, quick!
0:36:38 > 0:36:43Got it? OK. Now, draw the Roman numeral for nine. Ready?
0:36:43 > 0:36:46The challenge is to turn the numerals into six,
0:36:46 > 0:36:48using only one line.
0:36:48 > 0:36:49Can you work it out?
0:36:49 > 0:36:52Keep watching and you'll find out later in the show.
0:36:52 > 0:36:54Right now, though,
0:36:54 > 0:36:57Katherine's about to amuse some people in this amusement park
0:36:57 > 0:36:59with a trick you'll never work out.
0:36:59 > 0:37:02- Hi, guys.- Hi there. - This is Rebecca and Jess.
0:37:02 > 0:37:05They have no idea they're about to star in their own magic show.
0:37:05 > 0:37:06Watch carefully.
0:37:06 > 0:37:09Do any of you believe in power of the mind?
0:37:09 > 0:37:11- Yes.- No.
0:37:11 > 0:37:14Jess, I'm going to get you to have a look at both of these for me.
0:37:14 > 0:37:17We've got a mint and a coffee stirrer.
0:37:17 > 0:37:20Do they look perfectly normal to you?
0:37:20 > 0:37:21- Yeah.- OK.
0:37:21 > 0:37:24What I'd like you to do is hand me that back...
0:37:24 > 0:37:26- Watch carefully. - Watch very carefully.
0:37:26 > 0:37:29I'm going to draw some arrows on the mint,
0:37:29 > 0:37:30and you'll see why in a minute.
0:37:36 > 0:37:41If you could just thread the mint on the stick for me, that's perfect.
0:37:41 > 0:37:43YOU don't believe in the power of the mind,
0:37:43 > 0:37:46and you DO believe in the power of the mind?
0:37:46 > 0:37:49OK. Rebecca, I'm going to let you have the first go.
0:37:49 > 0:37:53What I'd like you to do is visualise the arrows moving towards you.
0:37:53 > 0:37:55- OK.- Can you do that?
0:37:56 > 0:37:57Keep concentrating.
0:37:59 > 0:38:02- There we go... - Your eyes are not lying to you.
0:38:02 > 0:38:04The mint is spinning on its own.
0:38:04 > 0:38:08What I want you to do, in your mind, is say, "Stop," in your mind.
0:38:08 > 0:38:12Wow! I wanted it to stop then too. She read my mind!
0:38:12 > 0:38:13Amazing!
0:38:13 > 0:38:16I want to look at that again. Let's get a rewind.
0:38:16 > 0:38:20What I want you do, in your mind, is say, "Stop," in your mind.
0:38:23 > 0:38:25It's Jess's turn now.
0:38:25 > 0:38:27- You don't believe in this, do you?- No.
0:38:27 > 0:38:30- So shall we see if you can manage to do this?- OK.
0:38:33 > 0:38:37And in your mind, I want you to say, "Stop."
0:38:37 > 0:38:39Whoa, that's awesome!
0:38:41 > 0:38:43She wrote the things on the Polo
0:38:43 > 0:38:47and then it started spinning without her doing anything.
0:38:47 > 0:38:49It was really weird.
0:38:49 > 0:38:53Now, I really, really believe in the power of the mind.
0:38:53 > 0:38:57Time to find out how to fool YOUR friends in Tricks Of The Trade.
0:38:58 > 0:39:00Me and John challenged you
0:39:00 > 0:39:02to turn this Roman numeral for the number nine,
0:39:02 > 0:39:04that's an I and an X,
0:39:04 > 0:39:06into six, using only one line.
0:39:06 > 0:39:08Come on, have you worked it out?
0:39:08 > 0:39:10Maybe you thought you could turn it into an number six
0:39:10 > 0:39:12by drawing around the X?
0:39:14 > 0:39:16Nah. Here's how.
0:39:21 > 0:39:22Did you get it?
0:39:22 > 0:39:25Are you amazing already?
0:39:25 > 0:39:29Now you've all got something to show off with in the playground.
0:39:32 > 0:39:36Fergus is in this shopping centre to play a trick on these girls.
0:39:37 > 0:39:39They've been set up by their parents.
0:39:39 > 0:39:42They have no idea what's about to happen.
0:39:42 > 0:39:45Here comes Fergus now. Check him out! What is he up to?
0:39:45 > 0:39:48Excuse me, sorry, do you have the time?
0:39:48 > 0:39:50Yeah, it's half past one.
0:39:50 > 0:39:52Half past one? I knew I'd set my watch wrong.
0:39:52 > 0:39:54I just bought, actually...
0:39:54 > 0:39:57I was just round the corner getting a cola,
0:39:57 > 0:40:00but it looks a little bit of a horrible colour, doesn't it?
0:40:00 > 0:40:04Mum and dad are watching on as Fergus tricks the girls.
0:40:04 > 0:40:08I wanted to get rid of it, but I couldn't find a bin.
0:40:08 > 0:40:13So, I thought the best way is to get rid of the liquid first, right?
0:40:13 > 0:40:15- Just get rid of the liquid... - How did he do that?!
0:40:15 > 0:40:18..and then I just need to bin the cup.
0:40:18 > 0:40:19So I'll go and do that now.
0:40:19 > 0:40:21Where did the cola go? Let's get a rewind.
0:40:24 > 0:40:26I can definitely see cola in there...
0:40:26 > 0:40:28..I couldn't find a bin.
0:40:28 > 0:40:31So, I thought the best way is to get rid of the liquid first, right?
0:40:32 > 0:40:34Just get rid of the liquid...
0:40:34 > 0:40:37and then I just need to bin the cup.
0:40:37 > 0:40:38..but now it's disappeared.
0:40:38 > 0:40:40I still can't work it out.
0:40:40 > 0:40:43Look at Ella's face. She can't believe it!
0:40:43 > 0:40:46What did they think of their shopping centre surprise?
0:40:46 > 0:40:48- Amazed. Amazed.- Yeah.
