0:00:02 > 0:00:04Warning, kids like you are on the loose with big explosions,
0:00:04 > 0:00:05big stunts and big laughs.
0:00:05 > 0:00:07Please do not try any of these at home...
0:00:08 > 0:00:11..except for the laughs. LAUGHTER
0:00:11 > 0:00:13Imagine if you had the chance to play epic pranks
0:00:13 > 0:00:15on an unsuspecting public,
0:00:15 > 0:00:20and access to the best special effects artists in the world,
0:00:20 > 0:00:25and imagine if a panel of Ranksters thinks your Public Prank is so good,
0:00:25 > 0:00:29you get to stage a Mega Prank on a target of your choice.
0:00:29 > 0:00:33Well, quit imagining. This is Rank The Prank.
0:00:43 > 0:00:46Which teams are battling today? Let's meet the Green team.
0:00:46 > 0:00:49- I'm Aengus.- And I'm Luca. - And we're...
0:00:49 > 0:00:50- BOTH:- ..the Prank Devils!
0:00:50 > 0:00:53We're really good friends cos not only do we both have so much
0:00:53 > 0:00:55in common, but we're both amazing pranksters
0:00:55 > 0:00:58and we get up to all kinds of mischief together.
0:00:58 > 0:01:01In our Public Prank, a boy and his mum are going
0:01:01 > 0:01:03to be testing hover boots.
0:01:03 > 0:01:06The boots go...and just fly away into the sky.
0:01:07 > 0:01:09If we get through to the Mega Prank,
0:01:09 > 0:01:12our target will be our rugby team coach.
0:01:12 > 0:01:14Our coaches are always in charge of us.
0:01:14 > 0:01:17This time, it's going to be us who's going to be controlling them.
0:01:17 > 0:01:20You're never safe because the Prank Devils are out and about.
0:01:20 > 0:01:22Well, I'd better make sure I'm staying in and going nowhere
0:01:22 > 0:01:24with these two around.
0:01:24 > 0:01:26Let's see what the Blue team has got.
0:01:26 > 0:01:29- I'm Bella.- And I'm Florrie. - And we're...
0:01:29 > 0:01:30- BOTH:- ..the Dancing Divas.
0:01:30 > 0:01:33The thing that makes me and Florrie such good friends is
0:01:33 > 0:01:37we're quite hyper and a bit crazy so we just laugh so much.
0:01:39 > 0:01:42For our Public Prank, we want to surprise everybody
0:01:42 > 0:01:46and make them think we have superhuman strength.
0:01:46 > 0:01:49If we make it to the Mega Prank, our target will be the whole class.
0:01:49 > 0:01:52When we surprise them, they'll just burst out laughing.
0:01:52 > 0:01:54Watch out, cos we're epic pranksters.
0:01:54 > 0:01:57And we'll be there when you least expect it.
0:01:57 > 0:02:00Well, you just told us, so I'm expecting it now, girls.
0:02:00 > 0:02:02But the teams aren't alone.
0:02:02 > 0:02:06We have some special effects experts to help bring their pranks to life.
0:02:06 > 0:02:07I'm Danny Hargreaves.
0:02:07 > 0:02:10I'm a physical special effects supervisor.
0:02:10 > 0:02:11I've worked on many productions,
0:02:11 > 0:02:14including Star Wars, Sherlock and Doctor Who.
0:02:14 > 0:02:16I actually blow up monsters for a living.
0:02:16 > 0:02:17That's my job.
0:02:17 > 0:02:19If a script has something visually demanding,
0:02:19 > 0:02:21it's my job to make it happen,
0:02:21 > 0:02:24so that would include sparks, explosions or alien goo.
0:02:24 > 0:02:27I mean, I could even change the weather.
0:02:27 > 0:02:28I can, really, honestly.
0:02:28 > 0:02:30So, come on, pranksters.
0:02:30 > 0:02:31Make something up
0:02:31 > 0:02:33and I will make it happen.
0:02:33 > 0:02:35I can't believe you made me say that.
0:02:35 > 0:02:38I can't believe you can actually change the weather, Danny.
0:02:38 > 0:02:41Next thing, you'll be telling me Effectors can fly.
0:02:41 > 0:02:42Oh, wait. Hang on a minute.
0:02:42 > 0:02:43I'm Nick Porter,
0:02:43 > 0:02:45supervising flying director.
0:02:45 > 0:02:47I've worked in all kinds of TV and theatre shows,
0:02:47 > 0:02:49including The X Factor and Harry Potter.
0:02:51 > 0:02:54I use wire-based systems to help performers float in a space,
0:02:54 > 0:02:57walk up walls and take to the skies.
0:02:57 > 0:03:00So whatever you pranksters come up with, I can make it fly.
0:03:00 > 0:03:04So with the Effectors on board, these pranks are ready to take off.
0:03:04 > 0:03:06Today's location - a park.
0:03:06 > 0:03:09Teams, welcome. Here we are. Would you like to go ahead
0:03:09 > 0:03:11and explain to the girls what your plan is?
0:03:11 > 0:03:13A boy and his mum are going to be testing out
0:03:13 > 0:03:17a new pair of hover boots but they can't get it to work,
0:03:17 > 0:03:19so they go to a stranger,
0:03:19 > 0:03:22ask them for help and hand them the remote.
0:03:22 > 0:03:24And then, something actually happens to the boots
0:03:24 > 0:03:27as they start sparking, smoke starts coming out.
0:03:27 > 0:03:30Aengus flies away into the sky and everybody's shocked.
0:03:30 > 0:03:32After hearing the Prank Devils' idea,
0:03:32 > 0:03:34it's made me a little bit more nervous.
0:03:34 > 0:03:36So, girls, what are we doing?
0:03:36 > 0:03:38A skip comes along and it accidentally drops
0:03:38 > 0:03:41on one of our teddies and we're really upset
0:03:41 > 0:03:43because we can't move the skip to get out the teddy.
0:03:43 > 0:03:47And a worker will go and ask the public to come and help
0:03:47 > 0:03:49pull the skip but no-one can do it,
0:03:49 > 0:03:53so either me or Bella will go up and try and pull the skip
0:03:53 > 0:03:55and we manage to do it
0:03:55 > 0:03:56and all sparks are going to fly out from the floor.
0:03:56 > 0:03:59The Dancing Divas' idea doesn't really make sense.
0:03:59 > 0:04:02Like, who drops a teddy bear under a skip?
0:04:02 > 0:04:03OK, boys. Well, you're up first.
0:04:03 > 0:04:05So I think we should go and do this. Let's go.
0:04:05 > 0:04:07Let's do it.
0:04:07 > 0:04:09We have a pair of out-of-control hover boots
0:04:09 > 0:04:12versus a teddy bear in need of rescuing.
0:04:12 > 0:04:14Only one team will go through to stage a Mega Prank.
0:04:14 > 0:04:16And only the Ranksters will decide
0:04:16 > 0:04:19who faces the Ejector Button Of Doom.
0:04:19 > 0:04:22First up, the Prank Devils.
0:04:22 > 0:04:26I'm a little bit nervous but, at the same time, really excited.
0:04:26 > 0:04:30They've come up with the idea of using rocket boots
0:04:30 > 0:04:32to propel someone up into the air.
0:04:32 > 0:04:35'We're going to make these rocket boots and I'm going to put a load'
0:04:35 > 0:04:37of pyrotechnics inside
0:04:37 > 0:04:41to create loads of sparks and loads of smoke.
0:04:41 > 0:04:42I'm really looking forward to this one.
0:04:42 > 0:04:44I think it's going to be really cool.
0:04:44 > 0:04:45Here you go.
0:04:45 > 0:04:47- Yeah?- They look awesome.
0:04:47 > 0:04:50- They look something that would just blast you off into space.- Yeah.
0:04:50 > 0:04:52This is, like, more than we expected.
0:04:52 > 0:04:56What we've done, OK, is we've taken a standard ski boot
0:04:56 > 0:04:57and we've adapted it.
0:04:57 > 0:04:59So the battery pack will fire this propeller
0:04:59 > 0:05:01which will blow loads of air down.
0:05:01 > 0:05:04And then, we'll have some pyrotechnic sparks
0:05:04 > 0:05:05coming out of here.
0:05:05 > 0:05:08Underneath, we've got, like, a smoke cartridge
0:05:08 > 0:05:09and some sparks as well.
0:05:09 > 0:05:11I knew it was going to be really good,
0:05:11 > 0:05:13but it was way more over-the-top
0:05:13 > 0:05:16than I originally thought, in a good way.
0:05:17 > 0:05:20- All right, then, guys, it's time to make you fly.- Awesome.
0:05:20 > 0:05:23I'm going to be providing a wire-lift system which we're going
0:05:23 > 0:05:26to attach to a tree immediately behind them, and that gives me
0:05:26 > 0:05:29the support to actually lift the weight of the boys
0:05:29 > 0:05:30up in the air.
0:05:30 > 0:05:34- Here we go. How does that feel? - Yeah, it's good.
0:05:34 > 0:05:36Whoa.
0:05:36 > 0:05:37It looks really cool.
0:05:37 > 0:05:40Resist the temptation to look down. Look more away to where the van is.
0:05:40 > 0:05:42That's better.
0:05:42 > 0:05:45There was a lot of ways I had to, kind of, position my body
0:05:45 > 0:05:46so it looked authentic.
0:05:46 > 0:05:48- It's not as easy as it looks, is it? - No.
0:05:48 > 0:05:50Everyone ready?
0:05:50 > 0:05:53Three, two, one, fire.
0:05:53 > 0:05:55BANG!
0:05:55 > 0:05:57OK. Go, go, go.
0:06:03 > 0:06:06It felt really, really cool and it was really thrilling.
0:06:08 > 0:06:11It was so amazing to actually see something come to real life.
0:06:11 > 0:06:13Boys, was that good? Did you like that?
0:06:13 > 0:06:15That felt like one of the coolest things ever.
0:06:18 > 0:06:20The Prank Devils are ready to blast off
0:06:20 > 0:06:22with the first Public Prank.
0:06:22 > 0:06:25The hidden cameras are rolling and everybody is in position,
0:06:25 > 0:06:26ready to fly.
0:06:26 > 0:06:29I just want it to start and then I just want to beat the other team.
0:06:32 > 0:06:36The latest craze gripping the nation is hover boots.
0:06:36 > 0:06:39What a shame that Aengus' fake mum can't get them to work.
0:06:39 > 0:06:41Excuse me! Can you help me?
0:06:41 > 0:06:44My son's just bought these hover boots
0:06:44 > 0:06:45and I really don't think they work.
0:06:45 > 0:06:47We got this remote control with it
0:06:47 > 0:06:49and it doesn't seem to be doing anything at all.
0:06:49 > 0:06:51They're just, like, making a buzzing noise.
0:06:51 > 0:06:52- Get ready. - Can you have a go?
0:06:52 > 0:06:53Here we go.
0:06:53 > 0:06:55Press that green button.
0:07:03 > 0:07:05- Aengus! Get down!- Mum! Oh, my God!
0:07:05 > 0:07:08- Get down from that tree! - They work!
0:07:08 > 0:07:11All of the reactions were just priceless.
0:07:11 > 0:07:13Tell them that that you're not very good with technology.
0:07:13 > 0:07:17I'm not very good with technology. Do you just press that green button?
0:07:17 > 0:07:20FAKE MUM SCREAMS
0:07:21 > 0:07:26Luca! Get down! I'll go and get your dad.
0:07:26 > 0:07:28They're not working.
0:07:28 > 0:07:31ALL SHOUT AT ONCE
0:07:31 > 0:07:34Get down! Get down!
0:07:35 > 0:07:38Some people reacted how I thought they would react.
0:07:38 > 0:07:40Some people reacted quite different.
0:07:40 > 0:07:42Will you have a go for me?
0:07:42 > 0:07:43Smoke up. Smoke up.
0:07:45 > 0:07:48He doesn't know what's going on.
0:07:48 > 0:07:49Aengus!
0:07:50 > 0:07:52What are you doing?! Get down!
0:07:52 > 0:07:54Are you OK?
0:07:54 > 0:07:56The man tried to help me down from it.
0:07:56 > 0:07:59I really wasn't expecting that. Thank you.
0:07:59 > 0:08:00DANNY LAUGHS
0:08:00 > 0:08:02Aengus! What have I told you?
0:08:02 > 0:08:04Show them the cameras.
0:08:04 > 0:08:07You've just been pranked by Rank The Prank.
0:08:07 > 0:08:09Wave at that camera.
0:08:09 > 0:08:12I was not expecting this when I came to the park.
0:08:14 > 0:08:16Very funny. Very good prank. Well done.
0:08:17 > 0:08:19The sparks were going everywhere.
0:08:19 > 0:08:21- I thought maybe his feet were going to blow off or something.- Yeah.
0:08:21 > 0:08:24It went really, really, really well.
0:08:24 > 0:08:26We're getting ready for the Mega Prank
0:08:26 > 0:08:28cos we know we're going to win this.
0:08:28 > 0:08:31So the Prank Devils think they're moving on up with their prank,
0:08:31 > 0:08:34but first, let's skip to the Dancing Divas.
0:08:34 > 0:08:36I'm really excited about working with the Effectors
0:08:36 > 0:08:37to see what they can do.
0:08:37 > 0:08:39So the story is
0:08:39 > 0:08:41this teddy bear is going to be trapped under a skip.
0:08:41 > 0:08:43Nobody can move it, nobody can push it,
0:08:43 > 0:08:45apart from this little girl.
0:08:45 > 0:08:47We've got a real skip,
0:08:47 > 0:08:50we're going to cut the bottom out of it, put it on casters.
0:08:50 > 0:08:51I think it's going to be good fun.
0:08:51 > 0:08:53So, girls, here we go.
0:08:53 > 0:08:55Here's the skip, but we've done a few modifications to it.
0:08:55 > 0:08:58We've got this section here, it's made of soft material.
0:08:58 > 0:09:00Give it a push. Show me your superhuman strength.
0:09:00 > 0:09:02Whoa! There you go.
0:09:02 > 0:09:05The soft part looks exactly like the skip,
0:09:05 > 0:09:07as you push it, it crumbles in,
0:09:07 > 0:09:10an it basically looks like you've got super-strength.
0:09:10 > 0:09:13- What do you reckon to that? - That's really cool.- So cool.
0:09:13 > 0:09:17So my part in this prank is to move the skip for the girls
0:09:17 > 0:09:18when they go to push it.
0:09:18 > 0:09:21So the most challenging thing about this effect is making sure
0:09:21 > 0:09:24that we don't move the skip at all until they push it
0:09:24 > 0:09:26and prevent it from being moved by anybody else
0:09:26 > 0:09:28in order to sell this as a really good illusion.
0:09:28 > 0:09:30If we can pull it off, it'll be amazing.
0:09:30 > 0:09:33As you can see, girls, we've got a wire coming from the back
0:09:33 > 0:09:36of the skip here - that's going to be pulling the skip this way,
0:09:36 > 0:09:37when you pretend to push on it.
0:09:37 > 0:09:38And then, when Whit pulls it,
0:09:38 > 0:09:40it means he can stand back out of sight.
0:09:40 > 0:09:43Nick showed us how there's just this, like,
0:09:43 > 0:09:47tiny little string and it can pull the whole skip.
0:09:47 > 0:09:50But how does such a small wire pull such a big skip?
0:09:50 > 0:09:53Well, it's a special wire and it's really strong,
0:09:53 > 0:09:55strong enough to pull a double-decker bus.
0:09:55 > 0:09:57- Oh, wow!- Wow!- That's so cool! - So no problems.
0:09:57 > 0:09:59So can we have a go?
0:09:59 > 0:10:01Yeah, absolutely. I think we should go give it a shot.
0:10:01 > 0:10:04Bella was pushing it before they were pulling it.
0:10:04 > 0:10:06It was kind of, like, impossible
0:10:06 > 0:10:09and we were really trying, but nothing couldn't move.
0:10:09 > 0:10:12In three, two, one, go.
0:10:16 > 0:10:20We actually got to kind of feel what it's like to be,
0:10:20 > 0:10:21like, a superhero, really.
0:10:21 > 0:10:24Now that we've seen how everything's going to work,
0:10:24 > 0:10:26I just really want to get started.
0:10:26 > 0:10:28- What do you think about that, Bella? - That was so cool.
0:10:29 > 0:10:31Now it's time for the second Public Prank.
0:10:31 > 0:10:34The hidden cameras are rolling, Mr Fluffy is in position
0:10:34 > 0:10:37and the girls are ready to show their superhuman strength.
0:10:37 > 0:10:40I just can't wait. I'm, like, shaking cos I'm just so excited.
0:10:44 > 0:10:47Ah! A lovely summer's day... No, wait!
0:10:47 > 0:10:50Poor Fluffy's stuck under that massive skip.
0:10:50 > 0:10:51Mr Fluffy!
0:10:51 > 0:10:55If only someone big and strong could come along and help set them free.
0:10:55 > 0:10:58There's a group of three people coming along.
0:10:58 > 0:11:01I've had this skip delivered and this little girl,
0:11:01 > 0:11:04I feel really sorry for her cos her teddy's stuck under it.
0:11:04 > 0:11:05Mr Fluffy!
0:11:05 > 0:11:08It needs to go back that much further.
0:11:08 > 0:11:09- It's this side. - It's this end, here.
0:11:09 > 0:11:12We actually got to, kind of, feel like a superhero.
0:11:12 > 0:11:14One, two, three...
0:11:14 > 0:11:16THEY HEAVE
0:11:16 > 0:11:19- No, it won't work. - Keep them going. Keep them going.
0:11:20 > 0:11:23- It's not going to work. - No, look, we've tried and we failed.
0:11:23 > 0:11:28- No, no, no. He's too delicate. - Just leave it. Just leave her.
0:11:28 > 0:11:31- Fine, I'll move it then. - Just leave her.
0:11:35 > 0:11:36Mr Fluffy!
0:11:36 > 0:11:37'It was so funny.'
0:11:37 > 0:11:39He was laughing his head off.
0:11:42 > 0:11:45Mr Fluffy, I've had him since I was born.
0:11:45 > 0:11:49- You've just dropped a skip on him! - I'll ask this guy.
0:11:49 > 0:11:52- Here they come, look. - Look what she did to my teddy.
0:11:52 > 0:11:53But I reckon, you know,
0:11:53 > 0:11:56it doesn't need much budging if we get from the middle.
0:11:56 > 0:11:58That's it. Push it. That's it.
0:11:58 > 0:12:01- Let me try. Let me try. - She's bossy, isn't she?
0:12:06 > 0:12:08Ready? And push...!
0:12:09 > 0:12:13- You lot are useless! - Now, don't you be rude.
0:12:13 > 0:12:14I'll have a go, then.
0:12:19 > 0:12:21- NICK:- He's going to try really hard. You watch.
0:12:21 > 0:12:25- WOMAN:- It's like on a pivot. So if you just push it, like...
0:12:25 > 0:12:28Let me try. I could probably do it with my own finger.
0:12:31 > 0:12:32Oh, wow!
0:12:32 > 0:12:35And I didn't even need any of you!
0:12:35 > 0:12:37You've just been pranked by Rank The Prank.
0:12:39 > 0:12:42She kicked a full skip out of the way, which was like, "Wow!"
0:12:42 > 0:12:43I thought, "I'll try and help them."
0:12:43 > 0:12:46And then a little girl moved it with her finger. Couldn't believe it.
0:12:46 > 0:12:48That was a very good prank.
0:12:48 > 0:12:51I think the prank went incredible.
0:12:52 > 0:12:54I just really hope that we can do the Mega Prank
0:12:54 > 0:12:56cos it would be amazing.
0:12:56 > 0:12:58Well, girls, you're about to find out.
0:12:58 > 0:13:01The Public Pranks are over, but which prankster pair
0:13:01 > 0:13:03will go on to do the Mega Prank?
0:13:03 > 0:13:05It's time rank the prank.
0:13:06 > 0:13:09Let's meet today's prank-loving panel.
0:13:09 > 0:13:12Ranksters, show yourselves.
0:13:12 > 0:13:14THEY CHUCKLE
0:13:14 > 0:13:18I liked the hover boots prank because I thought it was, like,
0:13:18 > 0:13:21really dramatic and it was a good use of special effects.
0:13:23 > 0:13:25My favourite bit was the reactions from the people.
0:13:25 > 0:13:27THEY LAUGH
0:13:27 > 0:13:31The prank that was my favourite was the hover boots prank.
0:13:31 > 0:13:32That was amazing.
0:13:32 > 0:13:35I really liked the skip one because the little girl
0:13:35 > 0:13:37who was doing it was like, "Oh, you're all useless."
0:13:37 > 0:13:39And they couldn't do it and then she did it with, like,
0:13:39 > 0:13:41her foot and her finger.
0:13:41 > 0:13:43I really liked the skip one cos it was unexpected
0:13:43 > 0:13:45that the girl was going to push the skip by herself.
0:13:45 > 0:13:46THEY GASP
0:13:46 > 0:13:49Both pranks were great. This is not an easy one for the Ranksters.
0:13:51 > 0:13:54The hour of judgment is upon them.
0:13:54 > 0:13:56It's up to the Ranksters who they like most.
0:13:56 > 0:13:59But I'm fairly confident that it's going to be us.
0:13:59 > 0:14:02Which team will make it through?
0:14:02 > 0:14:04It's going to be a really tough decision.
0:14:04 > 0:14:07We don't really know what's going to happen.
0:14:07 > 0:14:09Fingers crossed!
0:14:09 > 0:14:13And who will be sent home packing Hollywood-style?
0:14:15 > 0:14:19Green or Blue, jury of Ranksters, it's down to you.
0:14:19 > 0:14:21The votes have been counted.
0:14:22 > 0:14:24We have made a decision.
0:14:24 > 0:14:28The team going home today is...
0:14:31 > 0:14:33..the Prank Devils!
0:14:35 > 0:14:38- THEY GIGGLE - So exciting!
0:14:38 > 0:14:42I'm a bit disappointed, but it has been really good experience.
0:14:42 > 0:14:45We may have lost today, but the Prank Devils will be back.
0:14:45 > 0:14:47- Next is the Mega Prank. - Mega Prank!
0:14:47 > 0:14:49- It's so amazing.- It's so cool.
0:14:49 > 0:14:51- BOTH:- Our class at school better watch out!
0:14:51 > 0:14:54So the Dancing Divas have muscled their way
0:14:54 > 0:14:55through to the Mega Prank.
0:14:55 > 0:14:57But what have the Effectors got in store
0:14:57 > 0:14:58for their unlucky target?
0:15:01 > 0:15:04Our Mega Prank target is our class at school.
0:15:04 > 0:15:07They're always really mischievous and always prank us.
0:15:07 > 0:15:09So we thought it would be the best idea to prank them.
0:15:09 > 0:15:13I think the class are going to be so shocked
0:15:13 > 0:15:15but kind of laughing at the same time.
0:15:15 > 0:15:17And I think it'll be amazing.
0:15:17 > 0:15:22Looks like their class is going to have a lesson in pranking.
0:15:22 > 0:15:24Now for today's location - a theatre.
0:15:24 > 0:15:27It's time to get this show on the road.
0:15:27 > 0:15:31So, Nick and Danny, you did amazing in our Public Prank
0:15:31 > 0:15:33and we cannot wait to see our Mega Prank.
0:15:33 > 0:15:36So you chose this theatre, but why here?
0:15:36 > 0:15:40We've invited your entire class to come to a special lecture
0:15:40 > 0:15:42which is being given by an astronaut,
0:15:42 > 0:15:45well-renowned scientist, Dr Peter Rank.
0:15:45 > 0:15:47We made him up, all right? And because we've made him up,
0:15:47 > 0:15:50we've made him an expert in anti-gravity technology
0:15:50 > 0:15:55and he's developed these things - the anti-gravity energy bands.
0:15:55 > 0:15:56Energy bands?
0:15:56 > 0:15:58We're going to get your class to wear them and pretend
0:15:58 > 0:16:01that they create anti-gravity.
0:16:01 > 0:16:03You're going to go up on stage and help demonstrate
0:16:03 > 0:16:04how these things work.
0:16:04 > 0:16:07We're going to make you levitate some furniture into the air.
0:16:07 > 0:16:08- That's amazing!- Wow!
0:16:08 > 0:16:10It's furniture that I've already rigged with wires.
0:16:10 > 0:16:13Not only that - see that big bit of moon rock over there?
0:16:13 > 0:16:15That's going to explode and erupt.
0:16:15 > 0:16:17And then, finally, we're going to make you fly as well.
0:16:17 > 0:16:19- Cool!- So cool!
0:16:19 > 0:16:23When the Effectors showed us the storyboard, I felt just amazed.
0:16:23 > 0:16:26I think the idea is going to be amazing and I don't think the class
0:16:26 > 0:16:28are going to realise what's happening.
0:16:28 > 0:16:31'So to make this prank happen, we need to work with the girls
0:16:31 > 0:16:32'to fit them with harnesses,
0:16:32 > 0:16:34'train them to fly and hold themselves.'
0:16:34 > 0:16:38- I'm going to try and clip you on. All right?- This is crazy.
0:16:38 > 0:16:40Nick is responsible for making all of the objects fly,
0:16:40 > 0:16:42including us two.
0:16:42 > 0:16:45So just up slowly please, Adam.
0:16:45 > 0:16:46OK. Hold hands.
0:16:46 > 0:16:50- THEY GIGGLE - That's it. Good. How does that feel?
0:16:50 > 0:16:51- It feels good.- It's crazy!
0:16:51 > 0:16:53I've always wanted to be Peter Pan!
0:16:53 > 0:16:56We're just going to keep going up until we can get you out of view.
0:16:56 > 0:16:59- This is so crazy. - How are we going to get down?
0:16:59 > 0:17:02There's a lot of components that have made up this prank.
0:17:02 > 0:17:04The moon rock itself is made of polystyrene.
0:17:04 > 0:17:06It's not a real piece of moon rock.
0:17:06 > 0:17:10When Danny showed us the moon rock, I was so impressed and I had no idea
0:17:10 > 0:17:12that he could pull it out the bag like that again.
0:17:12 > 0:17:14Now I've seen everything the Effectors have done,
0:17:14 > 0:17:16I am so excited to see what happens.
0:17:16 > 0:17:19And I'm also so excited to see what the class thinks.
0:17:21 > 0:17:22Calling all prank fans,
0:17:22 > 0:17:25it's the moment you've been waiting for...
0:17:28 > 0:17:30So, the theatre is ready for the science lecture.
0:17:30 > 0:17:33And as the classmates file in, they have no idea that
0:17:33 > 0:17:36Bella and Florrie are going to make it a lesson they'll never forget.
0:17:36 > 0:17:39I felt a bit scared, but really excited.
0:17:39 > 0:17:42They were all here to watch us do a prank on them.
0:17:42 > 0:17:46Thank you very much, my name's Bob, it's lovely to have you here.
0:17:46 > 0:17:47Welcome to Space Rocks!
0:17:47 > 0:17:49We have a fake scientist,
0:17:49 > 0:17:53who is going to put on a whole show for our class.
0:17:53 > 0:17:55So I'd like you to join me in welcoming,
0:17:55 > 0:17:58with a huge round of applause, someone who's been to space...
0:17:58 > 0:18:00- No, he hasn't! - ..a physicist...
0:18:00 > 0:18:02- No, he's not! - ..a personal hero of mine...
0:18:02 > 0:18:03- Really? - ..would you please,
0:18:03 > 0:18:06with warm appreciation, a lovely round of applause,
0:18:06 > 0:18:07welcome Dr Peter Rank.
0:18:07 > 0:18:10- APPLAUSE - Hi.
0:18:10 > 0:18:13- Dr Rank, it's great to have you. - And it's nice to be here, thanks.
0:18:13 > 0:18:16Take a seat. Dr Rank, what sorts of things can you share from your
0:18:16 > 0:18:19experiences in the world of space?
0:18:19 > 0:18:22OK, well, we can do a few little experiments.
0:18:22 > 0:18:25So we're going to need some of these guys to help us out.
0:18:25 > 0:18:27I don't know if any of you would be up for that?
0:18:27 > 0:18:29I wonder who he's going to pick?
0:18:29 > 0:18:31That little lady there, in the front row.
0:18:31 > 0:18:33Let's have the two of you, OK?
0:18:33 > 0:18:35We stood up and went onto the stage, and I was a bit like,
0:18:35 > 0:18:37"Oh, no, this whole prank is relying on us."
0:18:37 > 0:18:40If it doesn't go right, then it's going to all be our fault.
0:18:40 > 0:18:42Now, if you go away with this lovely lady,
0:18:42 > 0:18:44she's going to get you kitted out, because we'll need some
0:18:44 > 0:18:48safety glasses and all the safety equipment that goes along with this.
0:18:48 > 0:18:50So while the girls get into their harnesses,
0:18:50 > 0:18:52Dr Rank demonstrates gravity.
0:18:52 > 0:18:54..an apple dropped off a tree...
0:18:54 > 0:18:56Impressive!
0:18:56 > 0:18:59But don't worry, because as the girls get ready,
0:18:59 > 0:19:03Dr Rank will demonstrate his anti-gravity bands.
0:19:03 > 0:19:06Within this coil, we've found a way of harnessing gravity,
0:19:06 > 0:19:11so we can pull gravity out of an object.
0:19:11 > 0:19:13Just going to slip this on here.
0:19:13 > 0:19:16If I pour my energy through this arm.
0:19:16 > 0:19:18- Just into here? - Just into that bowl of apples.
0:19:18 > 0:19:22An apple in the centre, which I am going to lift.
0:19:22 > 0:19:24- There's a little buzz... - Oh, my goodness me!
0:19:24 > 0:19:25A little buzz going up.
0:19:25 > 0:19:27Oh, my goodness, can you see that?!
0:19:27 > 0:19:29- You see that?- That's incredible!
0:19:29 > 0:19:31Now, the science here is
0:19:31 > 0:19:34I am pulling the gravity out of the apple.
0:19:34 > 0:19:36It's leaving the apple and going into the bracelet.
0:19:36 > 0:19:40- It's contained in these coils. - Oh, my goodness me!
0:19:40 > 0:19:44- I'm concentrating my energy. - That is incredible.
0:19:44 > 0:19:47It has to work kind of slowly at the moment.
0:19:47 > 0:19:48There we go, and it's back down.
0:19:48 > 0:19:52Oh, well done! I mean, that's absolutely incredible!
0:19:52 > 0:19:54- Some people were like... - GASPS
0:19:54 > 0:19:55Whoa!
0:19:55 > 0:19:57Well, we can go bigger than that,
0:19:57 > 0:19:59with a little help from Bella and Florrie.
0:19:59 > 0:20:02- Let's get our volunteers back. - Are you there, girls?
0:20:02 > 0:20:04Ah, here they go. They look like scientists, OK.
0:20:04 > 0:20:06They look like scientists,
0:20:06 > 0:20:09because the lab coats are hiding their harnesses. Sneaky!
0:20:09 > 0:20:11Straighten out the arm. Straight out, that's it.
0:20:11 > 0:20:13Now, everyone concentrate on that,
0:20:13 > 0:20:16and it will suck the gravity into the master....
0:20:16 > 0:20:20There goes the first one, there goes the second one!
0:20:20 > 0:20:22- OK!- Oh, my goodness!
0:20:22 > 0:20:25When the chairs were levitating, their jaws dropped to the floor.
0:20:25 > 0:20:27It was just incredible.
0:20:27 > 0:20:32There you go! OK, what about that? Give me five!
0:20:32 > 0:20:35The class seems to be falling for our anti-gravity bands.
0:20:35 > 0:20:38But are any of them convinced enough to try it themselves?
0:20:38 > 0:20:40Who'd like a go at this?
0:20:40 > 0:20:42Well, I guess that's all of you.
0:20:42 > 0:20:43Everybody get an armband,
0:20:43 > 0:20:46we're going to try and do something that we haven't yet attempted.
0:20:46 > 0:20:49As the class rush to collect the anti-gravity bands,
0:20:49 > 0:20:53Bella and Florrie are backstage getting their flying wires attached.
0:20:53 > 0:20:56I think nobody's going to realise what's happening.
0:20:56 > 0:20:59We're going to try to affect the gravity of the meteor.
0:20:59 > 0:21:01If everyone can just put the bracelet in front of them.
0:21:01 > 0:21:04Everybody, put their bracelet out. Open with the fingers.
0:21:04 > 0:21:08OK, so, everybody just focus and concentrate. Here we go.
0:21:08 > 0:21:10- Here we go, you ready, Bob? - OK.- Let's do this!
0:21:10 > 0:21:14So the whole class are generating anti-gravity to try and lift
0:21:14 > 0:21:16the moon rock, but is that really a good idea?
0:21:16 > 0:21:18Sorry, Dr Rank, what's the smoke there?
0:21:18 > 0:21:21It's probably just a side effect, that's fine.
0:21:21 > 0:21:22OK, keep concentrating...
0:21:24 > 0:21:29- No, no, no!- Whoa! - I think we should stop...- Whoa!
0:21:29 > 0:21:31Get them back down! Get them back down!
0:21:31 > 0:21:35- I was buzzing inside. - It was just incredible.
0:21:35 > 0:21:36Watch out for the roof, girls!
0:21:36 > 0:21:38CRASH!
0:21:39 > 0:21:41I think it's time to bring everyone back to Earth.
0:21:41 > 0:21:44Here we go, we got 'em. Houston, we don't have a problem.
0:21:44 > 0:21:46We were just going to announce to the whole class
0:21:46 > 0:21:48that they'd been pranked.
0:21:48 > 0:21:51- You've just been pranked! - On Rank The Prank!
0:21:51 > 0:21:55It went so amazing, they were all, like, "Oh, my...!"
0:21:55 > 0:21:57We thought, "Oh, it's just going to be
0:21:57 > 0:22:00"one of them boring science trips that we usually have."
0:22:00 > 0:22:03When we came on this school trip, we had no idea
0:22:03 > 0:22:05we were going to get pranked.
0:22:05 > 0:22:08They were great, and I think they'll be legends at their school now.
0:22:08 > 0:22:10It was absolutely amazing,
0:22:10 > 0:22:13because all of their expressions were so amazing.
0:22:13 > 0:22:15Bella and Florrie are really good at pranking us,
0:22:15 > 0:22:18and they're definitely one to watch.
0:22:18 > 0:22:21- ALL:- We've just been pranked on Rank The Prank!
0:22:21 > 0:22:23CHEERING
