0:00:33 > 0:00:36I'm Richard Hammond, and welcome to my Blast Lab!
0:00:36 > 0:00:38CHEERING AND APPLAUSE
0:00:38 > 0:00:40Actually, this top-secret lab of mine
0:00:40 > 0:00:45has this week had its top-secret status downgraded to medium secret,
0:00:45 > 0:00:46because MI5 uncovered us.
0:00:46 > 0:00:50Those guys have got some pretty serious surveillance equipment,
0:00:50 > 0:00:53but they didn't need it, they just watched us on the telly.
0:00:53 > 0:00:56Still, today we have two more teams of budding young brains
0:00:56 > 0:00:58lined up and ready to tackle science games,
0:00:58 > 0:01:01in the hope of winning some superb prizes. Coming up,
0:01:01 > 0:01:04our teams will navigate their way through some mind-boggling facts
0:01:04 > 0:01:06in Fact Nav 2.0 with Oliver.
0:01:06 > 0:01:10CHEERING AND APPLAUSE
0:01:10 > 0:01:12In Mini Science with Mini Miss,
0:01:12 > 0:01:15the teams play with some very ordinary household objects,
0:01:15 > 0:01:17and an extraordinary super magnet.
0:01:21 > 0:01:24Talking of ordinary, can some giant magnet gloves
0:01:24 > 0:01:28transform a less than average lab rat into a superhero?
0:01:32 > 0:01:36Today's Messy Messy Mess Test is the bridge-building masterclass that
0:01:36 > 0:01:40could teach Isambard Kingdom Brunel a thing or two about toxic gunge.
0:01:40 > 0:01:43It is of course the Bridge Of Destiny.
0:01:43 > 0:01:45The Bridge Of Destiny!
0:01:51 > 0:01:54This lab is like Fort Knox, except it's not in America.
0:01:54 > 0:01:57And it isn't full of gold. It's not like Fort Knox at all.
0:01:57 > 0:02:00But the security is just as tight, thanks to my Ninja Nan.
0:02:08 > 0:02:11She's busy sorting out the Senior Ninjas' coach trip to Eastbourne.
0:02:11 > 0:02:13They're going to a donkey sanctuary,
0:02:13 > 0:02:16and while they're in town, they'll eradicate street crime.
0:02:16 > 0:02:19Let's have a look at who's trying to get into my lab today.
0:02:24 > 0:02:27Hello! You say you're the Red Team.
0:02:27 > 0:02:30We need to check that for security purposes, obviously.
0:02:30 > 0:02:33Identify yourselves and I'll check them off. You are?
0:02:33 > 0:02:35- Orlin.- Thomas.- Elspeth.
0:02:35 > 0:02:37Orlin, Thomas, Elspeth. That's what I've got.
0:02:37 > 0:02:40It says under talent... Thomas, what are you going to do for us?
0:02:40 > 0:02:42I can do Morse code.
0:02:42 > 0:02:45That's what I've got down here, OK. How are you going to prove it?
0:02:45 > 0:02:47I'm going to say, "Tom."
0:02:47 > 0:02:50- What, in Morse code?- Yes.- OK, go.
0:02:50 > 0:02:54Beeeeeep, beep, beep, beep, beep, beep.
0:02:54 > 0:02:57It sounds like a squeaky gate to me, but I don't speak Morse,
0:02:57 > 0:03:00so I'm going to believe you. Come on into the lab, please. Well done.
0:03:00 > 0:03:03CHEERING AND APPLAUSE
0:03:04 > 0:03:06Beeeep, beep, beep-beep, beep.
0:03:06 > 0:03:08I was saying, "Welcome to Blast Lab." Fair enough.
0:03:08 > 0:03:11Lovely to have you here, but you've only got this far,
0:03:11 > 0:03:15there's one final check before we recognise you as the real Red Team.
0:03:15 > 0:03:17We've agreed a password with the Red Team.
0:03:17 > 0:03:19If you are the Red Team, you'd know it.
0:03:19 > 0:03:20It's Mr Stafford.
0:03:20 > 0:03:22Yes, it is! Why Mr Stafford?
0:03:22 > 0:03:26Because he's our headmaster, but he can be strict.
0:03:26 > 0:03:27Really? Well, headmasters can.
0:03:27 > 0:03:31That's official - you are our Red Team.
0:03:31 > 0:03:35Go and get ready for the first game. Away you go. There's your Red Team!
0:03:35 > 0:03:37Now, what we need is the Yellow Team,
0:03:37 > 0:03:40and these next three people claim to be them.
0:03:44 > 0:03:47OK, you three reckon you're the Yellow Team.
0:03:47 > 0:03:50We can't just take your word for it, we've got to check you through.
0:03:50 > 0:03:51So your names please, you are?
0:03:51 > 0:03:54- Cameron!- Alfie!- Nina!
0:03:54 > 0:03:57Yep, that's what I've got written down here.
0:03:57 > 0:03:59What are you going to do to prove yourselves?
0:03:59 > 0:04:01- I'm going to ballet dance!- Really?
0:04:01 > 0:04:03- Yes!- Crack on then, away you go.
0:04:07 > 0:04:10It's not the most graceful thing I've seen, but it's getting there.
0:04:10 > 0:04:12Come into the lab!
0:04:16 > 0:04:20- Is this ballet something you pursue regularly, then, Alfie?- Weekly.
0:04:20 > 0:04:23- Do you have to be very fit to do ballet?- Reasonably fit.
0:04:23 > 0:04:24It's going to be of no help
0:04:24 > 0:04:27whatsoever in the Blast Lab, just so you know.
0:04:27 > 0:04:31One final security check, before I accept you are the Yellow Team.
0:04:31 > 0:04:32We agreed a password,
0:04:32 > 0:04:36- you would know it if you are the Yellow Team, what is it?- Wee!
0:04:36 > 0:04:37Wee! Why is it that?
0:04:37 > 0:04:39Because my guinea pig's weed on them.
0:04:39 > 0:04:42Nice! Your guinea pig's weed on those two. Very...pleasant.
0:04:42 > 0:04:45OK, you are officially the Yellow Team.
0:04:45 > 0:04:47Go and get settled in ready for our first game!
0:04:51 > 0:04:54And here comes a car now that puts the smart into smart car,
0:04:54 > 0:04:57but takes the mobile out of automobile.
0:04:57 > 0:05:00It is my little yellow Opel Kadett, Oliver!
0:05:18 > 0:05:21Oliver, please, make yourself comfortable.
0:05:21 > 0:05:23Get him all docked in to Fact Nav.
0:05:23 > 0:05:26Right, that's it, system running.
0:05:26 > 0:05:28Now, to keep Oliver absolutely up-to-date,
0:05:28 > 0:05:33I installed the very latest upgrade, Fact Nav 2.0.
0:05:33 > 0:05:36I say installed, it didn't really seem to fit, so I had to...
0:05:36 > 0:05:39shove it into the dashboard a little bit,
0:05:39 > 0:05:41and some bits snapped off round the edge,
0:05:41 > 0:05:44and the front's a bit wonky, and as a result of that,
0:05:44 > 0:05:46not all the facts are correct.
0:05:46 > 0:05:48Teams, I'm going to need you to tell me
0:05:48 > 0:05:52whether the science facts I give you are true or false.
0:05:52 > 0:05:55If they turn out to be true, Oliver will then tell us.
0:05:55 > 0:05:58CAR HORN BLARES
0:05:58 > 0:06:00If they are false, Oliver will do this.
0:06:00 > 0:06:02FOGHORN BLARES
0:06:02 > 0:06:04OK, the game's pretty simple.
0:06:04 > 0:06:07Each team has three red lights right now.
0:06:07 > 0:06:09Every time you answer a question correctly,
0:06:09 > 0:06:11we will turn one of those lights green.
0:06:11 > 0:06:15The first to get all three lights green wins, they get a point,
0:06:15 > 0:06:16and we go on to the next game.
0:06:16 > 0:06:21One tiny little thing above that. If you get a question wrong,
0:06:21 > 0:06:23not only do we not light your light green,
0:06:23 > 0:06:25we light one green for the other team.
0:06:25 > 0:06:28So, you can win it for the other side.
0:06:28 > 0:06:30Be careful about your answers.
0:06:30 > 0:06:32We'll start with a nearest-to question.
0:06:32 > 0:06:35I'll give this to whoever's nearest to the answer.
0:06:35 > 0:06:38That team will then have control of the game at the very beginning,
0:06:38 > 0:06:41because they get the next true or false question. OK...
0:06:41 > 0:06:47How tall, in metres, is the tallest part of the Empire State Building?
0:06:47 > 0:06:49That's right to the very top of it,
0:06:49 > 0:06:52to the spike on the very top all the way down to the bottom.
0:06:57 > 0:07:00OK, both teams have got an answer written down.
0:07:00 > 0:07:03Let's see what you've got, Yellows.
0:07:03 > 0:07:05You've got 650 metres.
0:07:05 > 0:07:09Reds, you've got 850 metres.
0:07:09 > 0:07:12The real answer is 443.2 metres,
0:07:12 > 0:07:15so the Yellows are right, they get a green light,
0:07:15 > 0:07:17they seize control. Well done.
0:07:20 > 0:07:23Right, moving on. Here comes your true or false question.
0:07:23 > 0:07:28The human thigh bone is stronger than concrete.
0:07:28 > 0:07:29Is that true or false?
0:07:29 > 0:07:31The human thigh bone is stronger than concrete.
0:07:31 > 0:07:33Is that true or false? What do you think?
0:07:33 > 0:07:38We think it's true, because it's got to hold up all our weight.
0:07:38 > 0:07:39There's only one way to find out.
0:07:39 > 0:07:42Oliver, is it true or false?
0:07:42 > 0:07:45- CAR HORN BLARES - It's true, well done!
0:07:45 > 0:07:47A second light lit green for the Yellows.
0:07:49 > 0:07:51It's a good start, well done.
0:07:51 > 0:07:54Reds, here's the thing. This can change so quickly,
0:07:54 > 0:07:57you wouldn't believe, OK?
0:07:57 > 0:07:59Here is your science fact.
0:07:59 > 0:08:04Baby kangaroos are the size of an orange when they're born.
0:08:04 > 0:08:05Is that true or false?
0:08:05 > 0:08:09Baby kangaroos are the size of an orange when they are born.
0:08:09 > 0:08:11Is that true or false?
0:08:11 > 0:08:15- We think it's true. - You think it's true. Oliver?
0:08:15 > 0:08:18Just, you know, for the game,
0:08:18 > 0:08:20is it true or false?
0:08:20 > 0:08:21FOGHORN BLARES
0:08:21 > 0:08:24It's false, which means, I'm sorry, Reds,
0:08:24 > 0:08:26the light is lit green for the Yellows.
0:08:26 > 0:08:30CHEERING AND APPLAUSE
0:08:31 > 0:08:34You will kick yourselves, because when they're born,
0:08:34 > 0:08:37baby kangaroos are about the size, I kid you not, of a jelly bean.
0:08:37 > 0:08:41They're absolutely minute, they stay inside the pouch for ages.
0:08:41 > 0:08:43That means, then, Reds, sorry,
0:08:43 > 0:08:46the Yellows have stormed to the lead, three lights green,
0:08:46 > 0:08:50that means straightaway, it's 1-0 to the Yellows. Well done.
0:08:57 > 0:08:58Aaah!
0:09:08 > 0:09:09Now, not very long ago,
0:09:09 > 0:09:12I brought my old science teacher back through time,
0:09:12 > 0:09:15but the flux capacitor didn't sink in pulsar phase
0:09:15 > 0:09:17with the hyperdrive converter.
0:09:17 > 0:09:20Probably my fault for making it out of baked bean tins and string.
0:09:20 > 0:09:23But as a result, my old science teacher
0:09:23 > 0:09:24is now my young science teacher.
0:09:24 > 0:09:26It is of course Mini Miss.
0:09:26 > 0:09:27CHEERING AND APPLAUSE
0:09:32 > 0:09:33Hello, Miss.
0:09:33 > 0:09:37Do you remember all the good times we used to have back at school?
0:09:37 > 0:09:38Um, well, yes.
0:09:38 > 0:09:41There was that year before you arrived,
0:09:41 > 0:09:43and that year after you left.
0:09:43 > 0:09:44They were pretty good times.
0:09:44 > 0:09:46OK. Thanks, Miss.
0:09:46 > 0:09:48What are we doing today, then?
0:09:48 > 0:09:53Today, we're going to be seeing which household items are magnetic
0:09:53 > 0:09:55and which ones aren't, in a game I like to call...
0:09:58 > 0:10:01Let me guess. Each team is going to choose a household object.
0:10:01 > 0:10:03They'll take it in turns,
0:10:03 > 0:10:06and see if it's attracted to the magnet, and if it is,
0:10:06 > 0:10:10they get a point, and the team with the biggest number of magnetic items
0:10:10 > 0:10:13- at the end wins the game! - Yes, Richard, that's right.
0:10:13 > 0:10:15- Have a sticker.- Oh, thank you, Miss.
0:10:15 > 0:10:18By the way, I ate all my broccoli at lunchtime,
0:10:18 > 0:10:21- so technically, I deserve a gold star as well.- OK.
0:10:21 > 0:10:23Thank you, Miss, thank you.
0:10:23 > 0:10:25The score, Yellow Team, you're ahead.
0:10:25 > 0:10:27I've got two badges, look at that.
0:10:27 > 0:10:30Yellow Team, 1-0 to you, so you get to choose.
0:10:30 > 0:10:33- Do you want to go first or second?- First, please.
0:10:33 > 0:10:37OK, let's get into place, because it's time to get magnifinding.
0:10:37 > 0:10:39Come round here. Let's start.
0:10:42 > 0:10:46Yellow Team are going for a handful of paperclips.
0:10:47 > 0:10:50Some of these items may not look immediately magnetic,
0:10:50 > 0:10:52but think about how they might be constructed,
0:10:52 > 0:10:57what they might be made of inside to make them magnetic.
0:10:57 > 0:11:00Mini Miss is now going to lower the giant Blast Lab super magnet
0:11:00 > 0:11:05towards your pile of paperclips. This is...
0:11:05 > 0:11:07Nothing happening, nothing happening...
0:11:07 > 0:11:09Oh, this is a good sign!
0:11:09 > 0:11:11Oh, yes!
0:11:12 > 0:11:15That's a good first go, a point to the Yellows,
0:11:15 > 0:11:16well done.
0:11:16 > 0:11:19- Reds, what are you going for? - The clip.
0:11:19 > 0:11:21This is the karabiner. OK, step forward.
0:11:23 > 0:11:26OK, Mini Miss. Here we go.
0:11:26 > 0:11:28Lowering it down.
0:11:28 > 0:11:31Nothing happening. Nothing happening, this is...
0:11:31 > 0:11:34Oh, no!
0:11:34 > 0:11:37It's not worked! It's not worked.
0:11:37 > 0:11:40Sorry, Reds. That's one down to you.
0:11:40 > 0:11:41Yellows, it's your turn.
0:11:44 > 0:11:47Lots of things have little, tiny magnets inside them.
0:11:47 > 0:11:48Everything, it's called domains.
0:11:48 > 0:11:51In some things, it's easier for those little magnets
0:11:51 > 0:11:52to become lined up.
0:11:52 > 0:11:56That's what makes them magnetic. In some things, it's harder.
0:11:56 > 0:11:58That's what makes them not magnetic.
0:11:58 > 0:12:02And it doesn't matter, even if they're metal. Not all metals work.
0:12:02 > 0:12:04The Yellows, making their choice.
0:12:04 > 0:12:06- The Tinfoil.- Going for the tinfoil.
0:12:09 > 0:12:11Mini Miss, bringing the magnet down.
0:12:11 > 0:12:14Is it going to leap? Is it going to leap?
0:12:14 > 0:12:18Is it going to jump? Into the sky? It's not magnetic at all,
0:12:18 > 0:12:23it's not worked. So, it's still 1-0 to the Yellows, you're still ahead.
0:12:27 > 0:12:29The Reds have gone for the coffee tin.
0:12:29 > 0:12:33Mini Miss, if you'd like to administer the magnet... Ooh!
0:12:33 > 0:12:35Ooh!
0:12:35 > 0:12:38That was a great jump. Ooh!
0:12:38 > 0:12:42I thought you'd become magnetic, and you were going to stick to it.
0:12:42 > 0:12:44Right, OK. 1-1 is the score so far.
0:12:45 > 0:12:48- Yellows, you're going to go for the colander.- Yep.
0:12:50 > 0:12:53If the tiny little domains inside can line up,
0:12:53 > 0:12:57and it becomes magnetic, it will work. If not, it won't.
0:12:59 > 0:13:01Leap! Leap!
0:13:01 > 0:13:02Lift the magnet up.
0:13:02 > 0:13:04GROANING
0:13:04 > 0:13:05The colander did move,
0:13:05 > 0:13:07but that was only due to the weight of the magnet,
0:13:07 > 0:13:10rather than it actually being magnetic.
0:13:10 > 0:13:13So, with the Reds up next, the scores are one apiece.
0:13:13 > 0:13:15Well, Reds not messing about here.
0:13:15 > 0:13:17They've chosen the trowel, for gardening.
0:13:23 > 0:13:27Ooh, yes! Good play. 2-1 to the Reds.
0:13:27 > 0:13:32The Yellows are going for the tiny earphones. OK.
0:13:40 > 0:13:44Ah-ha! What actually happened, you couldn't see just behind there,
0:13:44 > 0:13:46we'll let you have that.
0:13:46 > 0:13:50Inside these headphones, there are small magnets.
0:13:50 > 0:13:53So, well done, Yellows, by the skin of your teeth,
0:13:53 > 0:13:57you're through. 2-2 is the score.
0:13:57 > 0:14:00The bicycle pump. OK. Give it a go.
0:14:00 > 0:14:03Let's have a look.
0:14:03 > 0:14:04Ooh...
0:14:06 > 0:14:09- Yes! - Do you know what?
0:14:09 > 0:14:12I'd say that's magnetic. That's counting.
0:14:12 > 0:14:14I'll let you into a secret,
0:14:14 > 0:14:17it would have gone there, because of what's inside it.
0:14:17 > 0:14:20There's enough metal in there. We'll let that through, well done, Reds.
0:14:20 > 0:14:22'It's the Yellows next, with four objects left.
0:14:22 > 0:14:25'Have they made up their minds?'
0:14:25 > 0:14:26Yeah, let's go for the mirror.
0:14:29 > 0:14:31Let's have a look. Here we go.
0:14:36 > 0:14:39Bad luck, Yellows. Reds, 3-2 to you guys.
0:14:39 > 0:14:41This is your chance to press home your lead.
0:14:41 > 0:14:44- Ah! Now, what do you think that is? - Metal.
0:14:46 > 0:14:49Ooh, look at that! It's actually steel wool,
0:14:49 > 0:14:53and steel is magnetic, so it works.
0:14:53 > 0:14:58'We're down to just two items, and the Yellows only have one go left,
0:14:58 > 0:15:00'so even if what they pick is magnetic...'
0:15:00 > 0:15:01You're going to go with the ship?
0:15:01 > 0:15:04'..from here, there's no chance they can win.'
0:15:05 > 0:15:08This is one of Ninja Nan's best shoes.
0:15:08 > 0:15:10She hasn't worn it for a while... Ooh!
0:15:11 > 0:15:14Look at that! Look at that!
0:15:14 > 0:15:17Well done, well done.
0:15:17 > 0:15:18OK, no choice for the Reds.
0:15:18 > 0:15:21In actual fact, there's metal inside the heel.
0:15:21 > 0:15:24- OK, Reds, no choice for you then. - This is the only choice.
0:15:24 > 0:15:274-3 to the Reds, so this is just to send it home.
0:15:31 > 0:15:33Nothing doing at the end.
0:15:33 > 0:15:35That means the final score is 4-3 to the Reds.
0:15:35 > 0:15:38You take the points. Well done.
0:15:38 > 0:15:41That means overall, the score now is 1-1.
0:15:41 > 0:15:44We've seen how useful magnets can be,
0:15:44 > 0:15:46but can they also be used to lift something bigger
0:15:46 > 0:15:48than any of these objects?
0:15:48 > 0:15:50Like a man?
0:15:52 > 0:15:55Meet normal Ken. Normal teeth,
0:15:55 > 0:15:56normal wind.
0:15:56 > 0:15:59- HE BREAKS WIND - Normal jokes.
0:16:04 > 0:16:07Tired of pushing people away, he decided to invent something
0:16:07 > 0:16:10to prove he was more than just normal.
0:16:10 > 0:16:14Normal Ken invented electromagnetic gloves,
0:16:14 > 0:16:18but what are electromagnetic gloves, and how do they work?
0:16:20 > 0:16:23Electromagnetic gloves are gloves made of giant electromagnets.
0:16:23 > 0:16:28An electromagnet is made by running electricity through coiled wires.
0:16:28 > 0:16:30This makes the wires act like a magnet,
0:16:30 > 0:16:35and so it can attract and stick to magnetic objects.
0:16:35 > 0:16:37When the electricity is switched off,
0:16:37 > 0:16:39the wire no longer acts like a magnet,
0:16:39 > 0:16:41and so it no longer sticks to the objects.
0:16:41 > 0:16:45With the gloves complete, he begins the testing process,
0:16:45 > 0:16:48but how much weight can his gloves hold?
0:16:48 > 0:16:50Can the gloves hold the weight of a teddy bear?
0:16:52 > 0:16:54That'll be a yes, then.
0:16:54 > 0:16:58Thanks, brave Ted. But now, we need to step up the experiment a notch.
0:16:58 > 0:17:01How about something heavier?
0:17:03 > 0:17:05Like a child's bicycle.
0:17:05 > 0:17:09Will the magnetic gloves be strong enough to hold the weight of a bike?
0:17:11 > 0:17:13OK. Another yes.
0:17:13 > 0:17:16The magnetic gloves showed no signs of weakness at all
0:17:16 > 0:17:20while supporting the weight of the bike. Well done, Ken.
0:17:20 > 0:17:23- Aaah! Help!- What's this?
0:17:23 > 0:17:26This poor woman's magnetic photo of a cat
0:17:26 > 0:17:28is stuck up that flat piece of metal.
0:17:29 > 0:17:31If only there was someone with super powers,
0:17:31 > 0:17:36someone who could climb up and save the cat. We need a hero!
0:17:36 > 0:17:38# Is it gravity
0:17:38 > 0:17:39# Chemistry
0:17:39 > 0:17:41# Physically pulling me?
0:17:42 > 0:17:44# What could it be, boy?
0:17:44 > 0:17:47# Cos I'm so drawn to you Like a fool
0:17:47 > 0:17:50# I keep coming back, it's true
0:17:50 > 0:17:53# I can't stand it
0:17:53 > 0:17:56# You're like a magnet You're like a magnet... #
0:17:56 > 0:17:58So, with the magnetic cat photo's life on the line,
0:17:58 > 0:18:01will Normal Ken - I mean Magnet Man -
0:18:01 > 0:18:04be able to climb the wall and save the day?
0:18:06 > 0:18:09Right, a question then, teams.
0:18:09 > 0:18:12This is important, because it's a draw, 1-1. This could be a decider.
0:18:12 > 0:18:15I will give another point to the team that can tell me...
0:18:15 > 0:18:19will Magnetic Man be able to climb the wall and save the magnetic cat?
0:18:19 > 0:18:21Just think about it before you answer,
0:18:21 > 0:18:23because there's a few factors here.
0:18:23 > 0:18:27Don't forget what you know about magnets. Also, there's human error.
0:18:27 > 0:18:31Well, I say human... Lab rat error, which is usually quite big.
0:18:31 > 0:18:34So, what do we think? Yellows are busy eating popcorn.
0:18:34 > 0:18:36You're enjoying that! Reds, what do you think?
0:18:36 > 0:18:38- Do you think he will? - We think he will.
0:18:38 > 0:18:40Yellows, do you think he'll manage it?
0:18:40 > 0:18:42We don't think he'll do it.
0:18:42 > 0:18:45OK, let's find out, carry on with the experiment.
0:18:47 > 0:18:51A humble man lived a humble existence.
0:18:51 > 0:18:53HE BREAKS WIND
0:18:53 > 0:18:55- But when fear rang out across the land...- Aaah!
0:18:55 > 0:18:56MIAOW!
0:18:56 > 0:18:59..it was only he that dared answer that call.
0:18:59 > 0:19:05Can he now banish a life of normality and become a someone?
0:19:07 > 0:19:11Or will the cat picture have to witness the fall of a man,
0:19:11 > 0:19:15the breaking of a spirit, the shattering of a dream?
0:19:17 > 0:19:19Here he goes.
0:19:19 > 0:19:21And so far, so good.
0:19:21 > 0:19:24The magnetic gloves are sticking to the surface,
0:19:24 > 0:19:26and supporting his weight.
0:19:26 > 0:19:30He's doing it, he's actually doing it.
0:19:30 > 0:19:32Who would have believed a man such as he
0:19:32 > 0:19:34could climb the heights of scientific achievement?
0:19:34 > 0:19:38A scientist, a hero!
0:19:38 > 0:19:41A cheat. He's not even off the ground.
0:19:41 > 0:19:45He's actually achieved nothing.
0:19:45 > 0:19:47And now, he's fallen off.
0:19:47 > 0:19:48Typical.
0:19:50 > 0:19:53Although Ken successfully invented magnetic gloves,
0:19:53 > 0:19:57his arms were just not strong enough to lift his body off the ground.
0:19:57 > 0:19:59CHEERING AND APPLAUSE
0:19:59 > 0:20:01So, those are the results. I'm sorry, teams,
0:20:01 > 0:20:05it is quite a harsh one, because what let us down wasn't science.
0:20:05 > 0:20:08Magnetism would have held him up easily,
0:20:08 > 0:20:10but he's a lab rat, he couldn't hold himself up.
0:20:10 > 0:20:13The point goes to the Yellows,
0:20:13 > 0:20:15it's 2-1 to the Yellows.
0:20:16 > 0:20:19Right, teams, go and get yourselves changed,
0:20:19 > 0:20:23because you're going to need those protective suits very soon.
0:20:23 > 0:20:25That was just rubbish.
0:20:25 > 0:20:28Turns out that his superpower was just a very ordinary power.
0:20:28 > 0:20:30It wasn't even much of a power at all.
0:20:30 > 0:20:33I guess it's back to his boring, ordinary life.
0:20:35 > 0:20:37So, defeat for Ken.
0:20:37 > 0:20:41He just has to admit he IS normal.
0:20:41 > 0:20:44And the world continues as normal.
0:20:44 > 0:20:46People walk about.
0:20:46 > 0:20:48- Play leapfrog.- Aargh!
0:20:48 > 0:20:50Throw grass.
0:20:50 > 0:20:54And a woman drops a needle in a haystack.
0:20:54 > 0:20:58If only there was someone with really strong magnets to help!
0:21:03 > 0:21:06Stop looking so pleased with yourself, with your stupid pose.
0:21:06 > 0:21:08That was rubbish.
0:21:08 > 0:21:11You did quite well with your outfit, your costume's good,
0:21:11 > 0:21:13but everything else about it was just awful.
0:21:13 > 0:21:15I bet you're not even magnetic, are you?
0:21:15 > 0:21:17Right, let's test.
0:21:18 > 0:21:21Yep, you are magnetic, well done. Now, get out. Right...
0:21:21 > 0:21:22CRASHING
0:21:22 > 0:21:23Yes, ooh!
0:21:29 > 0:21:32Maybe more magnetic than even he thought.
0:21:32 > 0:21:33Don't feel sorry for him though,
0:21:33 > 0:21:37it's time to move on to something far more important, it's time for...
0:21:40 > 0:21:42Which today, is the Bridge Of Destiny.
0:21:42 > 0:21:45The Bridge Of Destiny!
0:21:45 > 0:21:48Your prizes, which include a personal weather station,
0:21:48 > 0:21:51a radio-controlled rocket and a worm world,
0:21:51 > 0:21:54need to be transported across this tank.
0:21:54 > 0:21:56If they fall in, they'll be useless, as they'll melt instantly,
0:21:56 > 0:21:58so to keep them safe, teams,
0:21:58 > 0:22:01you have to construct your very own Bridge Of Destiny.
0:22:01 > 0:22:04The Bridge Of Destiny!
0:22:04 > 0:22:06Yes, yes, all right. Somewhere in that tank
0:22:06 > 0:22:09are all the bits that you need to build your own bridge.
0:22:09 > 0:22:12You need to find the pieces in the gunge, build your bridge,
0:22:12 > 0:22:15pull your lever, and do it in that order,
0:22:15 > 0:22:18because if you don't, your truckload of goodies will end up
0:22:18 > 0:22:21in the gunge-filled abyss below your Bridge Of Destiny.
0:22:22 > 0:22:25You really can't get the lab rats these days.
0:22:25 > 0:22:27When you think your bridge is finished,
0:22:27 > 0:22:28pull the lever, release the car,
0:22:28 > 0:22:31which will tow your trailer of prize pods across.
0:22:31 > 0:22:32OK, Yellows, you're in the lead,
0:22:32 > 0:22:34you get the five second head start.
0:22:34 > 0:22:38Reds, you wait until you hear the second klaxon.
0:22:38 > 0:22:41The race to get your prize pods across the tank starts...
0:22:41 > 0:22:42Let's think...
0:22:43 > 0:22:44..now!
0:22:44 > 0:22:47'And the Yellows are off,
0:22:47 > 0:22:49'wading slowly through a sea of green
0:22:49 > 0:22:51- 'that has no intention of parting.' - SIREN WAILS
0:22:51 > 0:22:53'There's the second siren.
0:22:53 > 0:22:56'Both teams now on the age-old search for bridge pieces
0:22:56 > 0:22:59'and immortality. Looks like Cameron for the Yellows has a piece,
0:22:59 > 0:23:02'but he's having more than a little trouble placing it.
0:23:02 > 0:23:07'Finally, it's in, and the Yellows have made a start.
0:23:07 > 0:23:09'The teams are flying now,
0:23:09 > 0:23:11'looking like kids dressed in waterproof outfits
0:23:11 > 0:23:13'trying to find pieces of a bridge
0:23:13 > 0:23:15'whilst up to their waists in green goo.
0:23:15 > 0:23:17'Literally looking like that!'
0:23:17 > 0:23:20Possibly the most astonishing thing,
0:23:20 > 0:23:22scientifically speaking, about this,
0:23:22 > 0:23:24is its ability to generate an argument,
0:23:24 > 0:23:26amongst any group of people.
0:23:26 > 0:23:28It's really... I love it!
0:23:28 > 0:23:29I'm not sure the teams always do.
0:23:31 > 0:23:35'Among the screams, it seems the Yellows are making some headway.
0:23:35 > 0:23:39'The Reds taking a quieter, more industrious approach,
0:23:39 > 0:23:42'but which will be the more successful?
0:23:43 > 0:23:45'And another piece in place for the Reds,
0:23:45 > 0:23:48'but neither team running away with it at the minute.
0:23:48 > 0:23:50'There's nothing to separate them.
0:23:52 > 0:23:55'The confusion continues.
0:23:55 > 0:23:57'The shouting continues, with neither team
0:23:57 > 0:24:01'really grasping that the aim of the game is to build a bridge.
0:24:01 > 0:24:03'Its name - Bridge of Destiny.
0:24:03 > 0:24:09'Not "big gaping hole over a load of green sludge" of Destiny.'
0:24:09 > 0:24:11Both teams really battling for this one.
0:24:11 > 0:24:13If I didn't enjoy their discomfort,
0:24:13 > 0:24:16misery and tension so much, it would be quite painful to watch.
0:24:16 > 0:24:20Fast approaching the moment when they have to make the decision.
0:24:20 > 0:24:23How much time will they then spend cleaning their finished bridge?
0:24:23 > 0:24:26If they spend too much, they could lose. Not enough...
0:24:26 > 0:24:29their trailer full of presents could dive off.
0:24:31 > 0:24:33'Utter mayhem out there.
0:24:33 > 0:24:36'But the Yellows have now activated the prize car.
0:24:36 > 0:24:40'Surely their bridge is too slidey, surely it will slip into the gunge!
0:24:40 > 0:24:44'Surely it's... Oh, apparently not. Well done, Yellows!'
0:24:44 > 0:24:46CHEERING
0:24:46 > 0:24:50Ha-ha! We have a result.
0:24:50 > 0:24:54The Yellow Team, that was a risky call there, I thought it was going
0:24:54 > 0:24:57into the abyss, but well done, that means we have clear winners.
0:24:57 > 0:25:00It is the Yellows. Let's have a look at what you've won. Ready?
0:25:00 > 0:25:02Each of you is taking home a metal detector.
0:25:02 > 0:25:04- One of those each. - CHEERING
0:25:04 > 0:25:05Yo-yo. One of those each.
0:25:05 > 0:25:07CHEERING
0:25:07 > 0:25:09- Worm World. - CHEERING
0:25:09 > 0:25:12- Radio-controlled rocket. - CHEERING
0:25:12 > 0:25:14- Building-block set. - CHEERING
0:25:14 > 0:25:17- Propeller racer. - CHEERING
0:25:17 > 0:25:20- Adventure tent. - CHEERING
0:25:20 > 0:25:23- A personal weather station. - CHEERING
0:25:23 > 0:25:25Each of you is taking home each of those prizes. Tremendous!
0:25:25 > 0:25:28Here's the thing, though, Reds, the most amazing coincidence -
0:25:28 > 0:25:30I'm really sorry,
0:25:30 > 0:25:32because you would have won exactly the same.
0:25:32 > 0:25:35But instead of taking all those exciting prizes home in one piece,
0:25:35 > 0:25:39you're going to do the complete opposite and leave all yours here
0:25:39 > 0:25:43in millions of tiny pieces, because it is time for Bidet Goes Bang!
0:25:49 > 0:25:50CHEERING
0:25:50 > 0:25:52Yellows, Yellows, well done.
0:25:52 > 0:25:55Well played, right at the end there, you leapt into the lead
0:25:55 > 0:26:01and you'll be taking all that home with you. So well done, Yellows.
0:26:01 > 0:26:03This is quite awkward, because they're just there,
0:26:03 > 0:26:08and you're just... Reds, I thought you had that in the bag. I'm sorry.
0:26:08 > 0:26:10It's not much of a consolation,
0:26:10 > 0:26:12all of these would have been coming home with you,
0:26:12 > 0:26:14but instead, you're going to blow them up.
0:26:14 > 0:26:18It's time for the Walk of Shame. It's a sombre moment for us all,
0:26:18 > 0:26:20I know, it's difficult.
0:26:20 > 0:26:22People find this moving. It's hard.
0:26:22 > 0:26:23I know.
0:26:28 > 0:26:30It's hard, it really is.
0:26:36 > 0:26:38Reds, I'm sorry,
0:26:38 > 0:26:41you played well, but it just didn't come right for you in the end,
0:26:41 > 0:26:44so the best thing to do is blow up all your prizes.
0:26:44 > 0:26:47If you'd like to lift the handle please and get ready, are you ready?
0:26:47 > 0:26:54Audience, we'll count them down. From - 5, 4, 3, 2, 1.
0:26:56 > 0:27:01CHEERING
0:27:01 > 0:27:04With the help of my lab rats, we have looked at magnets and found out
0:27:04 > 0:27:05just how attractive they can be -
0:27:05 > 0:27:08the magnets, not the lab rats. They are actually quite repulsive.
0:27:08 > 0:27:10Thanks for watching. See you next time.
