0:00:28 > 0:00:32CHEERING AND APPLAUSE
0:00:36 > 0:00:38There you go.
0:00:38 > 0:00:39It's finished.
0:00:39 > 0:00:42I've no idea what it does, but it looks brilliant.
0:00:42 > 0:00:45I wonder if it's safe to stand this close to it?
0:00:45 > 0:00:49I'm feeling quite warm down this side. I'll move away.
0:00:49 > 0:00:52Anyway, hello and thanks for joining me in my Blast Lab.
0:00:54 > 0:00:57This is the only laboratory in the world
0:00:57 > 0:01:01that allows large groups of kids to be close to dangerous chemicals.
0:01:01 > 0:01:05Well, I presume we're allowed. I've never actually checked.
0:01:05 > 0:01:08I'll be joined by two teams of bright young things
0:01:08 > 0:01:11who'll be doing science stuff to win some prizes.
0:01:11 > 0:01:13Coming up, we have Oliver,
0:01:13 > 0:01:16a car who has more questions than miles on the clock -
0:01:16 > 0:01:18that's saying something, in Fact Nav 2.0.
0:01:23 > 0:01:27Mini Miss will help the teams explore the science of flames.
0:01:32 > 0:01:36Meanwhile, Ninja Nan is flaming mad as she attempts a rocket stunt
0:01:36 > 0:01:39that even she must be a bit scared of.
0:01:43 > 0:01:45Then, we have the place that I'm scared of -
0:01:45 > 0:01:49my gunge tank, as our teams take on The Bridge of Destiny.
0:01:49 > 0:01:52The Bridge of Destiny!
0:01:56 > 0:02:01When it comes to keeping this place secure, I only employ the best.
0:02:01 > 0:02:06More specifically, I only employ the best 70-year-old Ninja in my family.
0:02:06 > 0:02:08Please welcome Ninja Nan!
0:02:15 > 0:02:18She and her friends are all together in the 'Nannexe' -
0:02:18 > 0:02:20they're watching an exercise DVD.
0:02:20 > 0:02:25It's called Exercise The Ninja Way, Lose Weight But Win Fights.
0:02:25 > 0:02:27Ah, pretty scary stuff.
0:02:27 > 0:02:31Let's have a look at who's trying to get into my lab today.
0:02:36 > 0:02:37Hello!
0:02:37 > 0:02:41All right, I'll admit, you look like you could be the Red Team,
0:02:41 > 0:02:45but for security purposes, identify yourselves by name.
0:02:45 > 0:02:47- Ryan.- EJ.- James.
0:02:47 > 0:02:50Ryan, EJ, James. Yep, that checks out.
0:02:50 > 0:02:53James, what are you going to do for Talent?
0:02:53 > 0:02:56I can produce a mind trick with this coin.
0:02:56 > 0:02:57What are you going to do?
0:02:57 > 0:03:01I can tell what side the coin is going to be on
0:03:01 > 0:03:03- without looking at it.- Go on, then.
0:03:03 > 0:03:07So, you've flipped the coin, OK.
0:03:07 > 0:03:10- I can tell that it's heads.- Is it?
0:03:10 > 0:03:13Can we have a look on the camera?
0:03:13 > 0:03:16Yeah, that's heads. Fair enough, come on in!
0:03:18 > 0:03:23Wow, Reds. That's a bit weird.
0:03:23 > 0:03:27Right, before we can absolutely trust you as our real Red Team,
0:03:27 > 0:03:32one final security check - Ninja Nan is still watching you to make sure.
0:03:32 > 0:03:36We agreed a password with the real Red Team - what is it?
0:03:36 > 0:03:38ALL: Lamppost.
0:03:38 > 0:03:40Yes! Lampposts.
0:03:40 > 0:03:42Just a word you picked? Why lampposts?
0:03:42 > 0:03:46Whenever I go on holiday, I always bang my head into lampposts.
0:03:46 > 0:03:50- What? Why?- I just got my attention round something else.
0:03:50 > 0:03:52So, you walk into lampposts.
0:03:52 > 0:03:56OK, Ryan, a budding young scientist, I'm quite sure.
0:03:56 > 0:03:59I believe you are our Red Team, go and get settled in.
0:03:59 > 0:04:02There they are. Lampposts?
0:04:02 > 0:04:05OK. What we need now, then, is a Yellow Team.
0:04:05 > 0:04:07These three people say it's them.
0:04:14 > 0:04:16Hello! Well, having yellow lab coats
0:04:16 > 0:04:21isn't enough to get through security. We need names, please.
0:04:21 > 0:04:24- Caitlin.- Megan.- Francesca.
0:04:24 > 0:04:27Yeah, that's what it says here.
0:04:27 > 0:04:29Caitlin, what Talent will you do for us?
0:04:29 > 0:04:33- I'm super bendy and I can do the splits.- Super bendy.
0:04:33 > 0:04:35Go on, then. Prove it.
0:04:37 > 0:04:40Oh, good Lord. Oh, she's all broken in half.
0:04:40 > 0:04:42She's all folded up!
0:04:42 > 0:04:43OK. Well, fair enough,
0:04:43 > 0:04:46that is super bendy, come on into the lab.
0:04:49 > 0:04:54Obviously, Caitlin, I could have done that, I just choose not to.
0:04:54 > 0:04:57Before I can let you any further than there
0:04:57 > 0:04:59into this lab for security reasons
0:04:59 > 0:05:01we have to be very careful.
0:05:01 > 0:05:04Now, we agreed a password with the real Yellow Team.
0:05:04 > 0:05:07If that is you, you'd know what it is. What is it?
0:05:07 > 0:05:10ALL: Bowling.
0:05:10 > 0:05:11Bowling it is!
0:05:11 > 0:05:14Is this is what you're doing later?
0:05:14 > 0:05:16Because when we went on a school trip
0:05:16 > 0:05:20I threw the ball into somebody else's lane and ruined the game.
0:05:20 > 0:05:25You were going bowling up that lane and it went into the lane next door?
0:05:25 > 0:05:27No, I threw it that way.
0:05:27 > 0:05:31I believe you. You are our Yellow Team, go and get settled in.
0:05:31 > 0:05:34Two teams, we've got two teams.
0:05:34 > 0:05:38Now, it's time to meet the car that's never been in the fast lane,
0:05:38 > 0:05:40but does have a huge brain. That is Oliver.
0:05:58 > 0:06:00Come on, Oliver.
0:06:00 > 0:06:04Please come in. He's getting dropped into Fact Nav, get him hooked up.
0:06:04 > 0:06:08There we go - system up and running. Good.
0:06:08 > 0:06:09I know, looking at Oliver,
0:06:09 > 0:06:13it's difficult to see how you could actually improve him.
0:06:13 > 0:06:16Maybe some new tyres, decent headlamps,
0:06:16 > 0:06:19a paint job, upholstery.
0:06:19 > 0:06:22There's a lot of ways you could make him better,
0:06:22 > 0:06:25but I chose to install Fact Nav 2.0 instead.
0:06:25 > 0:06:28It is brilliant. An upgrade to his Fact Nav system -
0:06:28 > 0:06:30millions of facts in there.
0:06:30 > 0:06:33The only problem is, I really did install it,
0:06:33 > 0:06:37and as a result, it doesn't really work very well.
0:06:37 > 0:06:38Teams, I need you to sort out
0:06:38 > 0:06:42whether the science facts I give you are true or false.
0:06:42 > 0:06:46Oliver will let us know. If it's true, he'll do this...
0:06:46 > 0:06:49HORN HOOTS
0:06:49 > 0:06:52And if it's false, he'll let us know by doing this.
0:06:52 > 0:06:54FOGHORN BLARES
0:06:54 > 0:06:57Here's how we play. Both teams have three red lights.
0:06:57 > 0:07:00Every time you answer correctly,
0:07:00 > 0:07:02one of your lights will be turned green.
0:07:02 > 0:07:05The first to get three green lights
0:07:05 > 0:07:07wins the game, takes a point and we move on.
0:07:07 > 0:07:09One little twist, though.
0:07:09 > 0:07:12That's what happens if you answer correctly.
0:07:12 > 0:07:14If you answer a question incorrectly,
0:07:14 > 0:07:18we'll turn one of the other team's lights green,
0:07:18 > 0:07:22which means you could win the game for the other team
0:07:22 > 0:07:26if you get it wrong. So, think carefully about your answer.
0:07:26 > 0:07:29First question is a Nearest To question.
0:07:29 > 0:07:31Here it comes.
0:07:31 > 0:07:34How many medium-sized cars could fit on the wing
0:07:34 > 0:07:37of a Boeing 747-400?
0:07:37 > 0:07:40Which is a really big aeroplane.
0:07:40 > 0:07:44Have a think, have a chat amongst yourselves. You never know.
0:07:44 > 0:07:47I don't know if you've parked cars on a plane's wing.
0:07:47 > 0:07:49Oh, got to hurry you, teams.
0:07:49 > 0:07:52Got answers written down? Yellows are ready.
0:07:52 > 0:07:54Reds are ready, too. OK.
0:07:54 > 0:07:56Yellows, what have you written down?
0:07:56 > 0:07:59- Lets have a look at your answer. - Ten.
0:07:59 > 0:08:04Ten medium-sized cars can be fitted on the wing of a 747-400.
0:08:04 > 0:08:07- Five on each wing. - That's the whole wing, yes.
0:08:07 > 0:08:10Reds, what do you think?
0:08:10 > 0:08:1112.
0:08:11 > 0:08:14Pretty close. Pretty precise answers.
0:08:14 > 0:08:16OK, the answer is...
0:08:17 > 0:08:21..45. Which means the Reds, with 12, are the nearest.
0:08:21 > 0:08:24They take the green light!
0:08:24 > 0:08:26Sorry, Yellows.
0:08:26 > 0:08:30In actual fact, the wing on it measures 524.9 square metres.
0:08:30 > 0:08:33Reds have got the first light lit green.
0:08:33 > 0:08:37You take control, you get the first True Or False question.
0:08:37 > 0:08:39Right, Reds. Here it is.
0:08:39 > 0:08:41The pattern of a tiger's stripes
0:08:41 > 0:08:44is exactly the same as its father's.
0:08:44 > 0:08:45True or false?
0:08:45 > 0:08:49The pattern of a tiger's stripes is the same as its father's.
0:08:49 > 0:08:51You have a think, Reds.
0:08:53 > 0:08:55Right, Reds. True or false?
0:08:55 > 0:08:57ALL: False.
0:08:57 > 0:08:59The Reds think false.
0:08:59 > 0:09:03Oliver, tell us, is it true or false?
0:09:03 > 0:09:04FOGHORN BLARES
0:09:04 > 0:09:07It's false. That's a second green light.
0:09:11 > 0:09:14No two tigers have the same pattern of stripes -
0:09:14 > 0:09:16it's like human fingerprints.
0:09:16 > 0:09:21Yellows, this is your science fact. Here it comes.
0:09:21 > 0:09:25The human body can conduct electricity.
0:09:27 > 0:09:28Is that true or false?
0:09:28 > 0:09:30Think - don't answer straight away.
0:09:31 > 0:09:35OK, the human body can conduct electricity -
0:09:35 > 0:09:36is that true or false?
0:09:36 > 0:09:38ALL: True.
0:09:38 > 0:09:41That's the answer the Yellow Team has given me.
0:09:41 > 0:09:45So, Oliver, for the Yellows to stay in the game
0:09:45 > 0:09:49and not lose immediately, do you think it's true or false?
0:09:49 > 0:09:51HORN HOOTS
0:09:51 > 0:09:53It's true! It's true! Oh, oh!
0:09:53 > 0:09:55Tense. Well done, Yellows.
0:09:55 > 0:09:58CHEERING AND APPLAUSE
0:10:00 > 0:10:02- Are you tense, girls? - Yeah, yeah.
0:10:02 > 0:10:06The human body is a good conductor of electricity
0:10:06 > 0:10:08because it is made mostly of water -
0:10:08 > 0:10:0970 per cent of us, I think,
0:10:09 > 0:10:12with salts dissolved in it
0:10:12 > 0:10:16which makes it ideal for conducting electricity.
0:10:16 > 0:10:20OK, Reds - the pressure's back on you, now,
0:10:20 > 0:10:23because if you get this right, you win.
0:10:23 > 0:10:27You get this wrong, the Yellows get a second green light
0:10:27 > 0:10:29and they can win on their next question.
0:10:29 > 0:10:34Right, here is your science facts. You tell me - is this true or false?
0:10:34 > 0:10:39The symbol for the chemical element potassium is K.
0:10:39 > 0:10:42Have a little chat. Audience, let's see what you think.
0:10:42 > 0:10:45Vote with your feet - is it true or false?
0:10:49 > 0:10:52What a lot of busy mind changing going on.
0:10:52 > 0:10:53What do we think?
0:10:53 > 0:10:56- I think it's false because it could be like a T.- OK.
0:10:56 > 0:11:01I just think I've seen the sign of K for describing potassium.
0:11:01 > 0:11:03You think you've seen something.
0:11:03 > 0:11:06Back to your places audience, thanks.
0:11:06 > 0:11:09- Reds, what do you think - is it true or false?- True.
0:11:09 > 0:11:13You think the symbol for the chemical element potassium is K.
0:11:13 > 0:11:16Oliver, tell us - is it true or false?
0:11:18 > 0:11:19HORN HOOTS
0:11:19 > 0:11:23It's true, which means the Reds get a third light lit green.
0:11:23 > 0:11:26CHEERING AND APPLAUSE
0:11:26 > 0:11:30It comes from the Latin name for potassium which is Kalium.
0:11:30 > 0:11:33That means with three green lights, the Reds win,
0:11:33 > 0:11:37so the score is one-nil to the Reds. Well done.
0:11:53 > 0:11:57Now, I don't remember much about school.
0:11:57 > 0:11:59Barely anything, actually.
0:11:59 > 0:12:02But one thing I do remember is my old science teacher.
0:12:02 > 0:12:05She may have been 65, but she was just so much fun -
0:12:05 > 0:12:08she was always laughing and joking around,
0:12:08 > 0:12:11and lessons with her were just such, such fun.
0:12:11 > 0:12:13So, I decided to build a time machine
0:12:13 > 0:12:16and bring her back through time to my lab.
0:12:16 > 0:12:18And it worked, kind of.
0:12:18 > 0:12:21It's just that she arrived looking like a 10-year-old.
0:12:21 > 0:12:22It's Mini Miss!
0:12:31 > 0:12:34I'm just fresh-faced, Richard!
0:12:34 > 0:12:36Yeah. What's worse is I didn't realise
0:12:36 > 0:12:40I was actually thinking about my geography teacher.
0:12:40 > 0:12:43- My science teacher was horrible. - What's that?- Nothing.
0:12:43 > 0:12:45No whispering in the lab!
0:12:45 > 0:12:49Sorry. So, what are we doing today? Can we do capital cities?
0:12:49 > 0:12:50No, Richard.
0:12:50 > 0:12:53Today, we're going to be exploring fire as we play...
0:12:56 > 0:12:57I'm all ears.
0:12:57 > 0:13:01We'll be testing out the ingredients they use to make fireworks.
0:13:01 > 0:13:04Here, we have six chemicals.
0:13:04 > 0:13:09The teams will take it in turns to choose a chemical,
0:13:09 > 0:13:14which is added to our fire to see what colour the flame will burn.
0:13:14 > 0:13:16Yeah, and then what?
0:13:16 > 0:13:18Each different colour
0:13:18 > 0:13:22- carries different points for the team that created it.- Yes.
0:13:22 > 0:13:25The team with the highest total score wins, but,
0:13:25 > 0:13:29the teams need to watch out for The Flame Of Disappointment.
0:13:29 > 0:13:34So, what exactly is The Flame Of Disappointment?
0:13:34 > 0:13:38One of the chemicals doesn't change the colour of the flame
0:13:38 > 0:13:41and is worth zero points.
0:13:41 > 0:13:44Yeah, I can see why that would be disappointing.
0:13:44 > 0:13:48Before you get started, Mini Miss is going to spend time with you
0:13:48 > 0:13:52talking you through your options - pay attention.
0:13:52 > 0:13:54Chemicals burn with different colours
0:13:54 > 0:13:56because of what they're made from.
0:13:56 > 0:13:59Chemicals are composed of different atoms
0:13:59 > 0:14:01so they react in different ways.
0:14:01 > 0:14:05When you burn something, the heat transfers into the atoms -
0:14:05 > 0:14:07that gives them more energy.
0:14:07 > 0:14:10This energy is released in the form of light
0:14:10 > 0:14:14and the colour of that light depends on the amount of energy released.
0:14:14 > 0:14:18All chemicals release different amounts of light energy,
0:14:18 > 0:14:20so we see different colours.
0:14:20 > 0:14:22That's what we'll see.
0:14:22 > 0:14:25Teams, I think that's enough thinking time,
0:14:25 > 0:14:27if we're all ready, then.
0:14:27 > 0:14:30Right. Now, Reds, you're in the lead.
0:14:30 > 0:14:33- Do you want to go first or second? - ALL: First.
0:14:33 > 0:14:36Choosing to go first could be the wrong decision,
0:14:36 > 0:14:40as The Flame Of Disappointment is in there somewhere.
0:14:40 > 0:14:43- Have you made your choice? - ALL: Yeah.
0:14:43 > 0:14:45- What is it?- Strontium chloride.
0:14:45 > 0:14:48They've gone for strontium chloride,
0:14:48 > 0:14:50if we can make that happen.
0:14:50 > 0:14:53Now, we're waiting for a colour change, remember.
0:14:53 > 0:14:56Oh, I'd say that was quite clearly a red flame.
0:14:56 > 0:14:59That means four points for the Reds. Well done!
0:15:05 > 0:15:07Yellows, your choice.
0:15:07 > 0:15:12- Have a look at them all, have a think.- ALL: Magnesium.
0:15:12 > 0:15:13OK, the magnesium.
0:15:13 > 0:15:16- The Yellows want - tell the Lab Rat.- Magnesium.
0:15:19 > 0:15:21That's a white light!
0:15:21 > 0:15:24That means five points for the Yellows.
0:15:24 > 0:15:27It looked red at first - that was leftover strontium chloride.
0:15:27 > 0:15:31We can then clearly see the magnesium burning bright white.
0:15:35 > 0:15:39- Reds, what they are doing is winning.- Yep.
0:15:39 > 0:15:41So, you better pick something else.
0:15:41 > 0:15:43We've got sodium chloride,
0:15:43 > 0:15:45we've got steel, copper sulphate
0:15:45 > 0:15:47and iron still to be chosen.
0:15:47 > 0:15:49ALL: Sodium chloride.
0:15:49 > 0:15:52OK, what are you anticipating?
0:15:52 > 0:15:55- Hopefully sparks. - The Reds want to see sparks.
0:15:55 > 0:15:58I think I can see an orangey-yellow flame.
0:15:58 > 0:16:01The red outer flame is leftover strontium,
0:16:01 > 0:16:03but that's yellow in the middle.
0:16:03 > 0:16:07Which means that's two points. Well done!
0:16:12 > 0:16:17Yellows you could still win this easily - you're only one behind.
0:16:17 > 0:16:21- Copper sulphate.- Copper sulphate. Lab Rat, let's have a go, please.
0:16:21 > 0:16:26Oh, is that green? That was green, I'd say that was green,
0:16:26 > 0:16:28which means that's one point for that.
0:16:30 > 0:16:35So, Yellows, that puts you on six points, so it's evens right now.
0:16:37 > 0:16:41Reds, you need to press home your advantage.
0:16:41 > 0:16:43We've still got sparks going for grabs.
0:16:43 > 0:16:46Were going to go for iron.
0:16:46 > 0:16:49Iron. What are you hoping for?
0:16:49 > 0:16:51- Sparks.- Thought you might be.
0:16:51 > 0:16:55At this crucial point in the game, Reds have to get this right.
0:16:55 > 0:16:59Sparks, they win. Flame Of Disappointment, they lose.
0:16:59 > 0:17:02It's tense. Oh, look at that -
0:17:02 > 0:17:06that clearly is sparks. That's another three points to the Reds.
0:17:06 > 0:17:08Reds win.
0:17:08 > 0:17:13All that leaves is the steel and that is The Flame Of Disappointment.
0:17:17 > 0:17:192-0 to the Reds.
0:17:19 > 0:17:22Don't worry, there's still a way to go.
0:17:22 > 0:17:25I do love small flames. It must run in the family
0:17:25 > 0:17:27because Ninja Nan loves massive flames.
0:17:27 > 0:17:30When offered the chance to muck about with rockets,
0:17:30 > 0:17:31she couldn't say no.
0:17:32 > 0:17:36Lab Rats are naturally very competitive creatures.
0:17:36 > 0:17:40Sadly, due to their complete lack of co-ordination, talent,
0:17:40 > 0:17:44and all-round mental ability, this never really shines through.
0:17:47 > 0:17:50See! Uncoordinated.
0:17:52 > 0:17:53Hopeless, really.
0:17:55 > 0:17:57CAT MEOWS
0:17:57 > 0:18:02Yet still, they try to compete against the unbeatable Ninja Nan.
0:18:02 > 0:18:05They play chess.
0:18:07 > 0:18:09They try to beat her at arm wrestling.
0:18:15 > 0:18:16They've had water fights.
0:18:19 > 0:18:22Each and every time coming in a distant second.
0:18:24 > 0:18:27Most recently, one of them challenged her
0:18:27 > 0:18:28to that well-known sport -
0:18:28 > 0:18:32Best At Wheeled Vehicle On A Ramp competition.
0:18:32 > 0:18:34Needless to say, she was unimpressed
0:18:34 > 0:18:38and decided to bury their feeble challenges once and for all.
0:18:38 > 0:18:41To aid her, she enlisted the help of this friend.
0:18:41 > 0:18:44Hi, I'm a lecturer in rocket propulsion
0:18:44 > 0:18:46at the University of Hertfordshire.
0:18:46 > 0:18:51Together, they have built her very own Ninja Rocket Nan Mobile.
0:18:51 > 0:18:54She was called to save the world at the last minute,
0:18:54 > 0:18:57so we've had to use a stunt double, instead.
0:18:57 > 0:19:01They will attempt to send this mean machine over this ramp
0:19:01 > 0:19:05and into the sky, using only the power of a single rocket.
0:19:05 > 0:19:09Sounds easy, but this makes it sound more impressive -
0:19:09 > 0:19:12our Nan rocket works by using solid fuel.
0:19:12 > 0:19:15This solid fuel is burnt very quickly
0:19:15 > 0:19:17to produce lots of hot, expanding gases
0:19:17 > 0:19:20which are pushed out the back of the rocket,
0:19:20 > 0:19:23launching it and the scooter forwards.
0:19:23 > 0:19:24Hopefully, over the ramp.
0:19:24 > 0:19:26So, the challenge is set.
0:19:26 > 0:19:32Can the Ninja Rocket Nan Mobile fly off the ramp and become airborne?
0:19:32 > 0:19:37Hold the experiment right there. There's another point up for grabs.
0:19:37 > 0:19:39Yellows, you could do with that point.
0:19:39 > 0:19:43I'll give that point to the team that can tell me -
0:19:43 > 0:19:48will Ninja Nan's scooter make it over the ramp and become airborne?
0:19:48 > 0:19:51OK? It's not an easy one. Have a little think.
0:19:51 > 0:19:54While you have a think, consider what's going on.
0:19:54 > 0:19:57It's un-Nanned, so there's no-one to steer it.
0:19:59 > 0:20:03- Yellows, will it work or will it not?- ALL: No.
0:20:03 > 0:20:05- Reds?- ALL: No.
0:20:05 > 0:20:07So, if it doesn't work, you both get a point,
0:20:07 > 0:20:10but Reds will still be in the lead.
0:20:10 > 0:20:12Let's find out what does happen.
0:20:13 > 0:20:16Ninja Nan's thirst for adventure,
0:20:16 > 0:20:19combined with the very latest in rocket science,
0:20:19 > 0:20:23combined with Blast Lab's love of ridiculous activities
0:20:23 > 0:20:25in the name of education,
0:20:25 > 0:20:28had led us, somehow, to this point.
0:20:29 > 0:20:33All the signs of a classic competition are here today.
0:20:33 > 0:20:35One ramp pointing to the sky.
0:20:35 > 0:20:38One rocket-powered granny chariot.
0:20:38 > 0:20:43One man dressed as Evel Knievel on a skateboard.
0:20:43 > 0:20:44OK, here we go.
0:20:44 > 0:20:47Three, two, one - blast off!
0:20:49 > 0:20:52We have liftoff! Amazing stuff! Let's watch that again.
0:20:54 > 0:20:57A perfect run-up, hitting maximum speed and the top of the ramp
0:20:57 > 0:20:59at the same time.
0:20:59 > 0:21:02She then flies off the top of the ramp,
0:21:02 > 0:21:04her wig flies off her head,
0:21:04 > 0:21:07she flies off the vehicle - so much flying in one experiment!
0:21:07 > 0:21:10She might need to work on her landing.
0:21:13 > 0:21:15Still, success!
0:21:18 > 0:21:19Sort of.
0:21:19 > 0:21:23You see! It works. You didn't think it would, it did.
0:21:23 > 0:21:26That means the scores stay the same.
0:21:26 > 0:21:282-0 to the Reds!
0:21:29 > 0:21:32If you'd like to get changed into clinical protection suits -
0:21:32 > 0:21:34you'll need them for the Messy Messy Mess Test.
0:21:34 > 0:21:39I think we owe it to Ninja Nan's stunt double to see that again.
0:22:04 > 0:22:06And now, it's time for...
0:22:10 > 0:22:14Comfortable? Comfortable but not entirely safe in there.
0:22:14 > 0:22:18Bobbing about in that hideous goo are pieces of a bridge.
0:22:18 > 0:22:21A bridge that is known as The Bridge Of Destiny.
0:22:21 > 0:22:25The Bridge Of Destiny!
0:22:25 > 0:22:30OK. Your job is to find all the pieces you need to make your bridge.
0:22:30 > 0:22:34As soon as you've finished, pull the lever to release your car
0:22:34 > 0:22:38to pull your trailer of prizes across the finish line.
0:22:38 > 0:22:41The finish line across The Bridge of Destiny.
0:22:41 > 0:22:44# The bridge, the bridge The bridge, the bridge
0:22:44 > 0:22:46# The Bridge Of Destiny! #
0:22:46 > 0:22:49This has got to stop, Lab Rats.
0:22:49 > 0:22:52The team that gets their car across first
0:22:52 > 0:22:54will win all the prizes, including,
0:22:54 > 0:22:58a model speed boat, a rocket alarm clock and a practical joke set.
0:22:58 > 0:23:01Do not let them fall from The Bridge Of Destiny.
0:23:01 > 0:23:04- # The Bridge - The Bridge
0:23:04 > 0:23:07# The Bridge
0:23:07 > 0:23:10# Of Destiny! #
0:23:10 > 0:23:13OK, teams, you know what you've got to do.
0:23:13 > 0:23:16Reds, you're in the lead, you go first.
0:23:16 > 0:23:20Yellows, you'll hear a second klaxon, that's when you start.
0:23:20 > 0:23:23The race to get your prize pods across the tank starts...
0:23:27 > 0:23:28..oh, now!
0:23:30 > 0:23:33Away go the Reds, searching for their bridge pieces.
0:23:33 > 0:23:35I think they have their first piece.
0:23:35 > 0:23:38Yes, they have their first piece in straight away.
0:23:38 > 0:23:43The Yellows waste no time in collecting their bridge parts.
0:23:43 > 0:23:44Oh, I did it again.
0:23:44 > 0:23:48I forgot to tell them about Alan, my humongus, sneezing robot.
0:23:48 > 0:23:53Oh, dear! He snots in the tank. They know now.
0:23:53 > 0:23:56Anyway, back to the game. This looks very close.
0:23:56 > 0:23:58Both teams have their pieces
0:23:58 > 0:24:01and are now trying to work out what order they go in.
0:24:01 > 0:24:04Reds have their second piece in.
0:24:04 > 0:24:08And their third and fourth. The Reds working like a machine out there.
0:24:08 > 0:24:14The Yellows are going to have to be very quick to win this one.
0:24:14 > 0:24:17And the final two sections are about to go in.
0:24:17 > 0:24:21Those Reds, faster than Ninja Nan on a rocket chariot.
0:24:21 > 0:24:23And away goes the car.
0:24:23 > 0:24:27CHEERING AND APPLAUSE
0:24:30 > 0:24:34I'd say the red car pretty much made it across the tank, there,
0:24:34 > 0:24:35and half-way across the lab.
0:24:35 > 0:24:39That means the winners are the Red Team!
0:24:42 > 0:24:44Looking at how close the Yellows were,
0:24:44 > 0:24:46you realise how close that was.
0:24:46 > 0:24:49Let's have a look at what you've won, Reds.
0:24:49 > 0:24:53Each of you taking home these - Ninja Nan, let's have a look.
0:24:53 > 0:24:54A board game.
0:24:56 > 0:24:57Practical joke set.
0:24:59 > 0:25:02A transforming ball.
0:25:02 > 0:25:05Rocket alarm clock.
0:25:05 > 0:25:08A butterfly garden.
0:25:08 > 0:25:10A model speedboat.
0:25:10 > 0:25:14Tomb Of Doom.
0:25:14 > 0:25:18Finally, a metal detector for each of you.
0:25:18 > 0:25:20What a haul of prizes, yeah.
0:25:20 > 0:25:24OK, Yellows. On Blast Lab, one team takes their prizes home,
0:25:24 > 0:25:28the other takes theirs to the home of explosives testing
0:25:28 > 0:25:31because it is time, now, for Bidet Goes Bang!
0:25:39 > 0:25:41Reds! Congratulations, Reds.
0:25:41 > 0:25:44All of this lot is coming home with you.
0:25:44 > 0:25:46- Don't you feel good?- Yeah. - Well done.
0:25:46 > 0:25:50Slightly awkward what I'm going to do now cos... Hi, Yellows.
0:25:50 > 0:25:53- Hi. - It's not the same feeling, really.
0:25:53 > 0:25:57- No.- I'm so sorry. You played so well and then what happened was,
0:25:57 > 0:26:00scientifically speaking, you lost.
0:26:00 > 0:26:02- Yes.- And as a result of that,
0:26:02 > 0:26:06you must now follow me on the walk for which no map is needed.
0:26:06 > 0:26:09It's time for The Walk Of Shame.
0:26:09 > 0:26:13AUDIENCE: Awwww.
0:26:13 > 0:26:17It's tough. It's difficult.
0:26:22 > 0:26:23Girls, I'm...
0:26:25 > 0:26:29We try to make it as easy for you as we can. Did that help?
0:26:29 > 0:26:32- No.- No? Not make it any easier at all, that?
0:26:32 > 0:26:36OK. Right, girls, you must first lift the plunger.
0:26:36 > 0:26:38It's some consolation to blow up the prizes
0:26:38 > 0:26:41that you would've taken home with you, isn't it?
0:26:41 > 0:26:44No. OK, audience, we'll count them down.
0:26:44 > 0:26:50From five, four, three, two, one.
0:26:50 > 0:26:53EXPLOSION
0:26:58 > 0:27:01We've had a great time learning about coloured chemistry
0:27:01 > 0:27:02and rocket power.
0:27:02 > 0:27:06It's been quite a ride - not just for Ninja Nan's scooter.
0:27:06 > 0:27:10Her stunt double's been signed up for the next three James Bond films.
0:27:10 > 0:27:11Goodbye.
