0:00:02 > 0:00:05It's a brand-new term and CBBC has sent these four magicians
0:00:05 > 0:00:08back to school. They're pretending to be supply teachers
0:00:08 > 0:00:14so that they can perform amazing magic on unsuspecting classes.
0:00:14 > 0:00:16But because you know and love them, this time,
0:00:16 > 0:00:19we've cunningly disguised them.
0:00:29 > 0:00:32This is Fergus. If he plays his cards right,
0:00:32 > 0:00:34he won't be recognised.
0:00:34 > 0:00:35Enter year five.
0:00:35 > 0:00:38So far, none of the class have noticed the hidden cameras
0:00:38 > 0:00:41in their school hall, or recognised Fergus in disguise.
0:00:41 > 0:00:44- Good morning, class. ALL:- Good morning...
0:00:44 > 0:00:47But will they be able to believe their eyes?
0:00:47 > 0:00:53Very good. Now, I'm actually from a company called Air Squash.
0:00:53 > 0:00:57And what we do is look at the space management
0:00:57 > 0:01:00on different forms of transport.
0:01:00 > 0:01:03So rather than have, say, 100 people on a plane,
0:01:03 > 0:01:07we'll fit 1,000 people on a plane. Sounds incredible, doesn't it?
0:01:07 > 0:01:11What happens with Air Squash is you arrive
0:01:11 > 0:01:14at your location for departure.
0:01:14 > 0:01:16These diagrams are here to help convince the class
0:01:16 > 0:01:18the lesson is real.
0:01:18 > 0:01:24Then you're placed into the contraption you'll see on your left.
0:01:24 > 0:01:31You're diminished to a fifth of your capacity, you're boxed,
0:01:31 > 0:01:37placed alongside other people until you reach your destination
0:01:37 > 0:01:42where you're elongated, you're stretched back to your regular size.
0:01:42 > 0:01:46- Would you like to see how this works? ALL:- Yes!
0:01:46 > 0:01:49Right, I have a colleague with me today, Miss Floyd,
0:01:49 > 0:01:53- who will be assisting.- Miss Floyd is actually a magician's assistant.
0:01:53 > 0:01:57Miss Floyd is going to step into our contraption.
0:01:57 > 0:02:00- The class don't suspect a thing. - Fantastic.
0:02:00 > 0:02:02And we will place this back here.
0:02:03 > 0:02:07And bring...that down.
0:02:08 > 0:02:10Lovely. So at the moment,
0:02:10 > 0:02:15you'll see Miss Floyd occupies the entire space of the box, right?
0:02:15 > 0:02:20What we want to do is to get Miss Floyd from her full size,
0:02:20 > 0:02:25squashed right down, able to fit in something that size.
0:02:25 > 0:02:28So far, Fergus has been telling the class tiny fibs.
0:02:28 > 0:02:31He's now about to make Miss Floyd smaller with a massive trick.
0:02:31 > 0:02:33We start...
0:02:33 > 0:02:37with the top of her body. So head, chest, tummy, back.
0:02:37 > 0:02:41And we squash that down, we contract
0:02:41 > 0:02:44all of those muscles...
0:02:47 > 0:02:51..until she's half of her original size.
0:02:51 > 0:02:56So now, what we need to do this time is work from the feet upwards.
0:02:56 > 0:03:00We need to contact the legs, the toes...
0:03:00 > 0:03:01I can't believe my eyes!
0:03:01 > 0:03:04I bet Miss Floyd can't believe her legs!
0:03:05 > 0:03:09Miss Floyd is that small.
0:03:11 > 0:03:15At that point, we can remove this as a package and we can put it into an
0:03:15 > 0:03:19aeroplane with lots of other people until you reach your destination.
0:03:21 > 0:03:24So we now have space for one, two,
0:03:24 > 0:03:28three, four, five Miss Floyds.
0:03:28 > 0:03:30Isn't that incredible?
0:03:30 > 0:03:33Fergus could even get underneath her feet through the Air Squash gizmo.
0:03:33 > 0:03:36Of course, once you get to your destination, you don't want to
0:03:36 > 0:03:39travel round like this all day, you need to be stretched out.
0:03:39 > 0:03:42So we start with the legs.
0:03:42 > 0:03:44So we bring those legs down...
0:03:48 > 0:03:53..until we have, just like we did last time, half Miss Floyd.
0:03:53 > 0:03:56Then we do the same but with the tummy, with the chest,
0:03:56 > 0:04:01with the back, and we stretch those muscles right the way out
0:04:01 > 0:04:08until Miss Floyd returns to her regular size.
0:04:08 > 0:04:12And then, of course, she can, she's now at her destination, step out...
0:04:14 > 0:04:18- ..and continue her holiday.- She deserves a holiday after all that.
0:04:20 > 0:04:23- Who would like to have one of them? ALL:- Me! Me! Me!
0:04:23 > 0:04:26Course they would. But I think they've also got a few questions
0:04:26 > 0:04:30- to ask you, mate.- The trouble is, none of you will own one of them.
0:04:30 > 0:04:35And the truth behind that is, I'm actually a magician
0:04:35 > 0:04:37and you're all going to be on
0:04:37 > 0:04:40Help! My Supply Teacher Is Magic. And there's a camera filming you in
0:04:40 > 0:04:43that corner there, and there's a camera there,
0:04:43 > 0:04:44and you're going to be on TV!
0:04:44 > 0:04:47No wonder they're excited. That was an unbelievable trick.
0:04:47 > 0:04:50But the class had no idea he was a magician.
0:04:50 > 0:04:52How long would it take for you to shout...?
