0:00:33 > 0:00:36CHEERING AND APPLAUSE
0:00:37 > 0:00:39Hello, and welcome to Blast Lab.
0:00:40 > 0:00:43Hello, and welcome to Bl... Hang on, what's going on?
0:00:43 > 0:00:44Whoops, wrong week.
0:00:44 > 0:00:46Are you me from the future?
0:00:46 > 0:00:50Well, yes. You see, next Tuesday, you're ill,
0:00:50 > 0:00:54and I've come back through time to stand in for you... Me.
0:00:54 > 0:00:56Can you tell me anything from my future, then?
0:00:56 > 0:01:01Well, no, I shouldn't, but seeing as you're you...me, us,
0:01:01 > 0:01:05Next week when you test that nanoparticle accelerometer,
0:01:05 > 0:01:08- make sure there's a lab rat standing in front of you.- Why?
0:01:08 > 0:01:12Let's just say there's a very good chance it'll go wrong
0:01:12 > 0:01:14and the lab rat takes one for the team.
0:01:14 > 0:01:18Well, rather him than you...me, us.
0:01:19 > 0:01:22Anyway, I'd better be shoving off, you've got a show to do.
0:01:22 > 0:01:23I'll see you in the future.
0:01:25 > 0:01:27Hello, and welcome.
0:01:27 > 0:01:30This IS Blast Lab and I AM its founder, Richard Hammond.
0:01:30 > 0:01:32CHEERING AND APPLAUSE
0:01:34 > 0:01:38In just several billion nanoseconds I shall be introducing two teams
0:01:38 > 0:01:40who'll be undertaking some extremely clever
0:01:40 > 0:01:43but a bit messy scientific challenges.
0:01:43 > 0:01:44The winners will get great prizes,
0:01:44 > 0:01:47the only thing the losers will get is a tissue,
0:01:47 > 0:01:50to share. And it's only on loan till they've stopped crying.
0:01:50 > 0:01:54Coming up today we have Fact Nav 2.0 with my fact-filled friend Oliver!
0:01:54 > 0:01:58CHEERING AND APPLAUSE
0:01:58 > 0:02:01In Mini Science the lab rats will be in the firing line
0:02:01 > 0:02:03as the teams target a point.
0:02:03 > 0:02:07CHEERING AND APPLAUSE
0:02:07 > 0:02:09Meanwhile some other lab rats
0:02:09 > 0:02:11will be targeting the back of the net
0:02:11 > 0:02:12with an extreme football experiment.
0:02:12 > 0:02:16CHEERING AND APPLAUSE
0:02:16 > 0:02:19And we return with hankies at the ready
0:02:19 > 0:02:23to the slimy, bogey mess created by my amazing Snot Bot!
0:02:23 > 0:02:26CHEERING AND APPLAUSE
0:02:26 > 0:02:30So to protect this lab from any evildoers, the building is fitted
0:02:30 > 0:02:32with an incredibly effective security system.
0:02:32 > 0:02:35That security system is called Ninja Nan.
0:02:43 > 0:02:47She's in the Nannex right now, let's take a peek at what she's up to.
0:02:47 > 0:02:48What's she doing?
0:02:48 > 0:02:51Oh, that's right, she's filling in her application
0:02:51 > 0:02:53for the Ultimate Fighting Championship.
0:02:53 > 0:02:56Don't know why she bothers, she's already been rejected twice.
0:02:56 > 0:02:58Not because of her age,
0:02:58 > 0:03:01but because the other competitors are scared. They won't fight.
0:03:01 > 0:03:04Let's have a look at who's trying to get in my lab today.
0:03:09 > 0:03:12Hello, welcome to the Nannex, but not the lab yet,
0:03:12 > 0:03:14because we've got to make sure you're who you claim to be.
0:03:14 > 0:03:18You claim to be the Red Team, identify yourselves by name please.
0:03:18 > 0:03:20- Chris.- Nicky.- Kevin.
0:03:20 > 0:03:23Chris, Nicky, Kevin, that's what I've got on my list, OK.
0:03:23 > 0:03:27Under talent, Kevin, what are you going to do?
0:03:27 > 0:03:28I can play the clarinet.
0:03:28 > 0:03:31That's what it says here. You're going to have to prove that.
0:03:31 > 0:03:36HE PLAYS AN ARPEGGIO
0:03:36 > 0:03:37Banging tunes.
0:03:37 > 0:03:40OK, fair enough, I believe you are the Red Team, come on into the lab.
0:03:40 > 0:03:45CHEERING AND APPLAUSE
0:03:45 > 0:03:46Welcome, chaps, nice to see you.
0:03:46 > 0:03:49You're in, but not completely through security yet.
0:03:49 > 0:03:53There's one final check. We agreed a password with the real Red Team.
0:03:53 > 0:03:55If you are the real Red Team, you'll know what it is.
0:03:55 > 0:03:57ALL: Bidet.
0:03:57 > 0:03:59Yes, that's what I've got here. Why?
0:03:59 > 0:04:03Cos when I was on holiday I didn't quite know what a bidet was,
0:04:03 > 0:04:05and I sort of brushed my teeth in one.
0:04:05 > 0:04:06Oh, Chris!
0:04:06 > 0:04:09Everybody knows bidets are for blowing prizes up!
0:04:09 > 0:04:11Everybody knows that.
0:04:11 > 0:04:13Go and get settled in ready for the first round.
0:04:15 > 0:04:18They are your Red Team, we know that much.
0:04:18 > 0:04:21Now let's meet the bunch claiming to be the Yellow Team.
0:04:26 > 0:04:29Hello. So you say you're the Yellow Team.
0:04:29 > 0:04:32All right, what names have I got here, then?
0:04:32 > 0:04:34- Georgina.- Emma.- Tanith.
0:04:34 > 0:04:38Georgina, Emma, Tanith, yeah, that's what I've got. Fair enough.
0:04:38 > 0:04:40Under talent, you won't believe what I've got,
0:04:40 > 0:04:43it says all three of you can put your foot under your armpit
0:04:43 > 0:04:45and hop at the same time.
0:04:45 > 0:04:48Clearly you can't do that, you're not the Yellow Team, get out.
0:04:48 > 0:04:50Unless you can. Can you?
0:04:50 > 0:04:51ALL: Yes.
0:04:51 > 0:04:52Well go on then.
0:04:52 > 0:04:54I don't... This can't be...
0:04:54 > 0:04:55What?!
0:04:55 > 0:04:58What a ridiculous thing to be able to do,
0:04:58 > 0:05:00but you must be the Yellow Team, come into the lab.
0:05:00 > 0:05:06CHEERING AND APPLAUSE
0:05:06 > 0:05:08I'd really like to know, girls,
0:05:08 > 0:05:11how did you find out you could do that? What a strange thing to do.
0:05:11 > 0:05:13Fair enough. You're into the lab,
0:05:13 > 0:05:16but you're not entirely through security yet.
0:05:16 > 0:05:18Ninja Nan still has her eye on you, OK?
0:05:18 > 0:05:22One final check, we agreed a password with the real Yellow Team.
0:05:22 > 0:05:24If you are them, you'd know what it is.
0:05:24 > 0:05:26What is the password?
0:05:26 > 0:05:27ALL: Empty child.
0:05:27 > 0:05:30That's what it says here. What does it mean?
0:05:30 > 0:05:33We all love Doctor Who, and Empty Child's
0:05:33 > 0:05:36- the only character that we're afraid of.- Aah! Behind y...
0:05:36 > 0:05:38No, you're all right. It was just a chair. Don't worry.
0:05:38 > 0:05:42Go and get settled in for the first game. Good luck.
0:05:42 > 0:05:45CHEERING AND APPLAUSE
0:05:45 > 0:05:48Now let us meet a very special car indeed.
0:05:48 > 0:05:52Very slow-moving, he may not be able to overtake a slow-moving badger,
0:05:52 > 0:05:55but he can tell you what the Latin name for one is. Oliver!
0:05:55 > 0:05:58No, it's not... That's not the Latin name, obviously,
0:05:58 > 0:06:00that's Oliver's name for Oliver!
0:06:17 > 0:06:19Good to see you, Oliver.
0:06:19 > 0:06:23I'll get him docked into his Fact Nav system, just connect him up.
0:06:23 > 0:06:27There. Right. Now, recently I bought a very expensive
0:06:27 > 0:06:31and very hi-tech upgrade for Oliver, Fact Nav 2.0.
0:06:31 > 0:06:34And it said in the instructions that it was simple to install
0:06:34 > 0:06:36in two steps.
0:06:36 > 0:06:37"Fantastic," I thought.
0:06:37 > 0:06:39It's just that the first step turned out to be
0:06:39 > 0:06:42"get a PhD in advanced micro-electronics,"
0:06:42 > 0:06:45and the second step was "install it."
0:06:45 > 0:06:48The result is, it works, sort of,
0:06:48 > 0:06:52just that not every fact I get out of it is correct.
0:06:52 > 0:06:56So teams, it's up to you to tell me whether they're true or false.
0:06:56 > 0:06:57If it's true, Oliver will do this.
0:06:57 > 0:07:00HORN BLARES
0:07:00 > 0:07:03If it's false, he'll let us know by doing this.
0:07:03 > 0:07:05SHIP'S HORN BLASTS
0:07:05 > 0:07:08OK, simple enough. And here's how the game works.
0:07:08 > 0:07:10Each team has on its side, three lights,
0:07:10 > 0:07:12currently lit red.
0:07:12 > 0:07:14Every time you answer a question correctly,
0:07:14 > 0:07:15we will light a light green.
0:07:15 > 0:07:18The first team to get all three lights lit green
0:07:18 > 0:07:20will win the point, and we move on.
0:07:20 > 0:07:22It's that simple. Oh, there's one other thing.
0:07:22 > 0:07:25If you answer a question correctly your light turns green.
0:07:25 > 0:07:28If you're wrong, they get a green light.
0:07:28 > 0:07:31So you can win the game for the other team if you're not careful.
0:07:31 > 0:07:33OK, everybody knows the rules.
0:07:33 > 0:07:34Let's get on with it.
0:07:34 > 0:07:38The first question is to decide who gets the first light lit green
0:07:38 > 0:07:39and who takes control of the game.
0:07:39 > 0:07:42So we start with a nearest-to question.
0:07:42 > 0:07:46How tall was the smallest adult dog ever recorded?
0:07:46 > 0:07:50I'll have the answer in centimetres, that seems best. OK?
0:07:50 > 0:07:52Have a think.
0:07:52 > 0:07:56How tall was the smallest adult dog ever recorded?
0:07:56 > 0:07:58Oh, got to answer! There we go.
0:08:00 > 0:08:03- Do both teams have an answer written down?- Yes.- Yes.
0:08:03 > 0:08:06Good. Let's have a look, Yellows.
0:08:06 > 0:08:0930 centimetres for the Yellows. Reds, what do you say?
0:08:10 > 0:08:1320 centimetres. Both answers not that far apart.
0:08:13 > 0:08:15The real answer was
0:08:15 > 0:08:196.5 centimetres, about there!
0:08:19 > 0:08:23- So the Red Team win that one!- Yes! - CHEERING AND APPLAUSE
0:08:23 > 0:08:27That means, Reds, you seize control right at the beginning, well done.
0:08:27 > 0:08:31That's a green light lit for you, and you get the first question.
0:08:31 > 0:08:32Concentrating, chaps?
0:08:32 > 0:08:34Concentrate on this. It's very important.
0:08:34 > 0:08:39Chewing gum comes from a tree. Is that true or false?
0:08:39 > 0:08:42Chewing gum comes from a tree, is that true or false?
0:08:42 > 0:08:44- What do you think?- True.- True.
0:08:44 > 0:08:45You think it's true?
0:08:45 > 0:08:48Let's find out from Oliver for your second green light,
0:08:48 > 0:08:52or to make it a draw and give a green light to the Yellows. Oliver,
0:08:52 > 0:08:53is it true or false?
0:08:53 > 0:08:55HORN BLARES
0:08:55 > 0:08:58It is true, well done! Well done Reds.
0:08:58 > 0:09:00CHEERING AND APPLAUSE
0:09:00 > 0:09:01It's actually made from chicle,
0:09:01 > 0:09:03which is a gum made from the naseberry tree,
0:09:03 > 0:09:07a tropical American fruit tree. I don't think it grows in packets,
0:09:07 > 0:09:09you have to actually turn it into chewing gum. OK,
0:09:09 > 0:09:12that's two green lights lit for the Reds,
0:09:12 > 0:09:13you have none yet, Yellows,
0:09:13 > 0:09:15now's your first chance to light one.
0:09:15 > 0:09:19Bamboo is the fastest-growing grass on earth.
0:09:19 > 0:09:21Is that true or false?
0:09:21 > 0:09:25Bamboo is the fastest-growing grass on earth.
0:09:25 > 0:09:28- Do you think that's true or false? - True.- True.
0:09:28 > 0:09:30You're in agreement, you believe it's true.
0:09:30 > 0:09:32Oliver, is it true or false?
0:09:32 > 0:09:34HORN BLARES
0:09:34 > 0:09:36- It's true!- Yes!
0:09:36 > 0:09:39CHEERING AND APPLAUSE
0:09:39 > 0:09:42Right, Reds. Get this right, you win the game.
0:09:42 > 0:09:45Get this wrong, it's a draw and they can win next time round.
0:09:45 > 0:09:47OK, here is your science fact.
0:09:47 > 0:09:5242% of the earth's surface is covered in water.
0:09:52 > 0:09:53Is that true or false?
0:09:53 > 0:09:5742% of the earth's surface is covered in water.
0:09:57 > 0:10:00Is that true or false do you think?
0:10:00 > 0:10:01- False.- You think it's false.
0:10:01 > 0:10:04Oliver, is it true or false?
0:10:04 > 0:10:06SHIP'S HORN
0:10:06 > 0:10:08Yes, it's false, that means the third light goes green,
0:10:08 > 0:10:11the Reds win! Well done, Reds!
0:10:11 > 0:10:13Yellows, I'm sorry.
0:10:13 > 0:10:14Sorry, girls.
0:10:14 > 0:10:17It's not over yet, don't worry. There's a lot more to come.
0:10:17 > 0:10:21It's about 71% of the earth's surface is taken up with water,
0:10:21 > 0:10:24including all the oceans, seas and lakes added together.
0:10:24 > 0:10:27Right, so that means at the end of the first round,
0:10:27 > 0:10:30with three lights lit green the Reds win that game,
0:10:30 > 0:10:32and the score is 1-0 to the Reds.
0:10:32 > 0:10:36CHEERING AND APPLAUSE
0:10:48 > 0:10:54Now, I know a bit about science, but for this next experiment
0:10:54 > 0:10:57I need someone who knows a lot about science,
0:10:57 > 0:11:00so I've built a time machine to bring my old science teacher
0:11:00 > 0:11:03from school through time to the lab to help me.
0:11:03 > 0:11:04It went really well,
0:11:04 > 0:11:08it's just that whilst doing it I got distracted.
0:11:08 > 0:11:10Chuggington was on the telly,
0:11:10 > 0:11:13and so I left the time machine on a bit too long.
0:11:13 > 0:11:16So now my science teacher looks like a ten-year-old girl.
0:11:16 > 0:11:17She is of course Mini Miss!
0:11:17 > 0:11:19CHEERING AND APPLAUSE
0:11:23 > 0:11:25Hello, Miss. Can I just say,
0:11:25 > 0:11:30you taught me everything I know about science.
0:11:30 > 0:11:31Well, it's not really something
0:11:31 > 0:11:34for me to show off about though, is it, Richard?
0:11:34 > 0:11:37No, Miss. So what will our teams be doing today?
0:11:37 > 0:11:40Well, today we're going to be using leaf blowers and balls
0:11:40 > 0:11:44to learn about air pressure, by playing...
0:11:44 > 0:11:48Why are there two lab rats hanging from the ceiling up there?
0:11:48 > 0:11:50Did they forget to do their homework?
0:11:50 > 0:11:53No, Richard. They are the targets.
0:11:53 > 0:11:54Oh, I'm getting the picture.
0:11:54 > 0:11:57So our teams will use the leaf blowers behind them
0:11:57 > 0:12:00to fire these balls at the lab rats, and because the air
0:12:00 > 0:12:04coming out of the leaf blowers is moving faster than that around it,
0:12:04 > 0:12:08the ball will be propelled, and hopefully hit the lab rat.
0:12:08 > 0:12:09- That's right.- I see.
0:12:09 > 0:12:13The team with the most ball-covered lab rat once the time is up
0:12:13 > 0:12:14wins the game.
0:12:14 > 0:12:16OK, so that's the balls left sticking to the lab rat,
0:12:16 > 0:12:20and it doesn't matter what colour, a red on the yellow side still counts.
0:12:20 > 0:12:24Teams, be careful with you aim. The rules are clear I think,
0:12:24 > 0:12:26we understand what we have to do.
0:12:26 > 0:12:29Teams, you have some time to stick as many balls to your lab rat
0:12:29 > 0:12:35using a leaf blower, and that some time starts, let's say, now.
0:12:35 > 0:12:36Carry on.
0:12:36 > 0:12:39'Gentlemen and ladies, start your engines.
0:12:39 > 0:12:40'Oh, they have.
0:12:40 > 0:12:43'And already we have Velcro ball on lab rat action.'
0:12:47 > 0:12:49What we're watching is all about the Bernoulli principle.
0:12:49 > 0:12:53Science says things like to be where there's low pressure.
0:12:53 > 0:12:57Here, the leaf blowers are creating a column of fast-moving air,
0:12:57 > 0:13:01and the faster the air goes, the lower the pressure of the air.
0:13:01 > 0:13:05So there's a column of low-pressure air coming from the leaf blower,
0:13:05 > 0:13:08which our beach balls just like to hang out in.
0:13:08 > 0:13:11In theory this means we should be able to angle the blower,
0:13:11 > 0:13:13and the balls shouldn't fall out of the jet,
0:13:13 > 0:13:14even when it's not vertical.
0:13:14 > 0:13:17It does look sometimes as though our teams
0:13:17 > 0:13:19are just using the push of the air stream,
0:13:19 > 0:13:22but that is the Bernoulli principle going on.
0:13:22 > 0:13:25The reason the balls are sticking to the lab rats is Velcro,
0:13:25 > 0:13:28the lab rats are covered with lots of tiny hooks,
0:13:28 > 0:13:30and the balls with tiny loops.
0:13:30 > 0:13:34So when the two come into contact they stick together.
0:13:34 > 0:13:37It's not as uncomfortable as it looks for the lab rats, sadly.
0:13:41 > 0:13:44'The teams just peppering their respective lab rats now,
0:13:44 > 0:13:47'who really are beginning to resemble
0:13:47 > 0:13:49'two lab rats wearing red and yellow sticky suits
0:13:49 > 0:13:52'strung from the ceiling whilst two teams fire balls at them
0:13:52 > 0:13:54'to try and win points on a science game show,
0:13:54 > 0:13:59'which is exactly what they are. It's uncanny.
0:14:00 > 0:14:02'It's neck and neck out there now,
0:14:02 > 0:14:07'with nothing to separate the teams apart from the actual score.
0:14:09 > 0:14:13'Oh, some classic skills on display here, absolute concentration
0:14:13 > 0:14:15'from both teams.
0:14:18 > 0:14:22'There really is no room for error with the standard set so high.'
0:14:28 > 0:14:31SIREN BLARES
0:14:31 > 0:14:34Time is up for both teams, come round here please.
0:14:34 > 0:14:37Well done, that looked like hard work.
0:14:37 > 0:14:40I think both teams did magnificently, now we must find out
0:14:40 > 0:14:42who has got the most balls stuck to their lab rats.
0:14:42 > 0:14:44So, let's have a look.
0:14:44 > 0:14:47Count the number of balls sticking to that lab rat, please.
0:14:47 > 0:14:50Oh, he really is stretching himself to do this(!)
0:14:50 > 0:14:54Only so many fingers on his paws. 16? 16?!
0:14:54 > 0:14:5616 balls on that lab rat for the Yellows, well done!
0:14:56 > 0:15:00Now the Reds, now the Reds.
0:15:01 > 0:15:02Ten...
0:15:04 > 0:15:07Ten. 19. 19 for the Reds!
0:15:07 > 0:15:09It's a win for the Reds!
0:15:09 > 0:15:13It's a win for the Reds! That's takes the score to 2-0 to the Reds.
0:15:13 > 0:15:16Of course, while firing balls at Lab Rats is certainly fun,
0:15:16 > 0:15:19it is really only a minority sport.
0:15:19 > 0:15:21I want to bring ball-firing science to the masses,
0:15:21 > 0:15:24using something like football.
0:15:26 > 0:15:30One pathetic example of, well, the human race,
0:15:30 > 0:15:33better known as a typical lab rat, with one single goal -
0:15:33 > 0:15:36to kick this ball into this goal.
0:15:36 > 0:15:41I know he's not fit, but surely the water's going a bit far.
0:15:42 > 0:15:45And crisps! Anyway, here he goes.
0:15:48 > 0:15:52Oh, you've got to be kidding. After all that, he misses! Come on!
0:15:52 > 0:15:55Incompetent fool!
0:15:55 > 0:15:58HE SOBS
0:15:58 > 0:16:00Oh!
0:16:00 > 0:16:04All right, pull yourself together. It's not the end of the world.
0:16:04 > 0:16:07Go and get the ball from over there and... Hang on a second.
0:16:07 > 0:16:09You're not meant to go in there.
0:16:09 > 0:16:12That's where I keep my time machine, the Cardis.
0:16:12 > 0:16:16No, come back here with that!
0:16:16 > 0:16:19This could end badly.
0:16:22 > 0:16:24All right, look, whatever you do,
0:16:24 > 0:16:27don't go too fast or you'll end up going back in time. Oh, no.
0:16:27 > 0:16:31Oh, and now he's back. Who's that he's got with him? It can't be.
0:16:31 > 0:16:38The legendary lab rat, legendary Dutch international football icon
0:16:38 > 0:16:41from the legendary '80s. And he's come back from the past
0:16:41 > 0:16:44to attempt to score the longest football goal ever!
0:16:44 > 0:16:48There have been some really famous long-distance goals.
0:16:48 > 0:16:50Rivaldo for Barcelona against Deportivo.
0:16:50 > 0:16:53David Beckham from Man United versus Wimbledon.
0:16:53 > 0:16:57Both scored from their own half, but there isn't an official world record
0:16:57 > 0:16:59for the longest football goal,
0:16:59 > 0:17:02so today we're going to try and set one.
0:17:02 > 0:17:06Here we go. Marco's going to attempt to score from a pitch length away -
0:17:06 > 0:17:09at least 90 metres.
0:17:14 > 0:17:18He's come all the way from the '80s and he's missed an open goal.
0:17:18 > 0:17:20It's time for real science to lend a hand.
0:17:22 > 0:17:25What we need is my trusty air cannon.
0:17:25 > 0:17:28Now we're going to see some special science.
0:17:28 > 0:17:30For our air canon to work,
0:17:30 > 0:17:33it's loaded with a football weighted with sand.
0:17:33 > 0:17:36It's then filled with compressed air.
0:17:36 > 0:17:39When the cannon is fired, this compressed air is quickly released
0:17:39 > 0:17:42into the barrel of the cannon, with the force of this air
0:17:42 > 0:17:44shooting the football out of the end.
0:17:49 > 0:17:52So will science overcome the odds that all others have failed?
0:17:52 > 0:17:56Will our football cannon score a goal and set a world record?
0:17:56 > 0:18:01And will Marco's haircut ever come back into style?
0:18:02 > 0:18:06Hold the experiment there, because there's a point up for grabs
0:18:06 > 0:18:08for a question I'm going to ask.
0:18:08 > 0:18:11The score is 2-0, so you can't take the lead,
0:18:11 > 0:18:15but I think it's worth going for the point anyway. Here is the question.
0:18:15 > 0:18:18Will my football cannon score a goal?
0:18:18 > 0:18:22Some things you need to know. The football has been filled with sand
0:18:22 > 0:18:26so it's less likely to get blown off course. That's important.
0:18:26 > 0:18:31There is also no existing world record for this.
0:18:31 > 0:18:33We are in uncharted territory. Yellows, what do you think?
0:18:33 > 0:18:36- Yes.- You think yes. Reds?
0:18:36 > 0:18:40- Yeah.- We think it will.- You think yes. There's a point up for grabs.
0:18:40 > 0:18:44Let's find out and carry on with the experiment.
0:18:45 > 0:18:49It's all come to this very moment,
0:18:49 > 0:18:51from a stupidly long run-up to an appalling shot.
0:18:51 > 0:18:56To time-travelling cars and '80s icons who've come from the past
0:18:56 > 0:18:58and yet still missed the goal.
0:18:58 > 0:19:01And now here we are, with an air cannon.
0:19:01 > 0:19:04Can this experiment be any weirder?
0:19:04 > 0:19:06Let's find out with our attempt at
0:19:06 > 0:19:10the world record longest football goal.
0:19:10 > 0:19:15As you know, we've filled the ball with sand to keep it on course.
0:19:15 > 0:19:17OK, is everyone ready?
0:19:17 > 0:19:20Five, four,
0:19:20 > 0:19:22three, two,
0:19:22 > 0:19:24one, fire!
0:19:29 > 0:19:31Oh, I can't believe it!
0:19:31 > 0:19:38The air cannon has scored, nay, it has destroyed the goal.
0:19:40 > 0:19:44So, conclusive proof that science can overcome all obstacles
0:19:44 > 0:19:47and score the longest football goal ever.
0:19:50 > 0:19:52APPLAUSE
0:19:52 > 0:19:56I think we can safely say that that works, so that's a point apiece,
0:19:56 > 0:19:58taking the score to 3-1. Well done, both teams.
0:19:58 > 0:20:01Go and get into your protective suits, away you go.
0:20:01 > 0:20:06Round of applause, as they get ready for the Messy Messy Mess Test.
0:20:06 > 0:20:08We managed to not only score a goal
0:20:08 > 0:20:12but completely destroy the actual goal as well.
0:20:12 > 0:20:15I rather hope that's the end of the time-travelling today.
0:20:17 > 0:20:19Oh, hang on a second, Marco,
0:20:19 > 0:20:23you'd better not be thinking what I think you're thinking.
0:20:23 > 0:20:25If you are thinking what I think you're thinking,
0:20:25 > 0:20:28you'd better not be thinking it.
0:20:28 > 0:20:33Oh, no. Marco's stolen my time machine, the Cardis,
0:20:33 > 0:20:35and has gone back in time again.
0:20:37 > 0:20:41What's this? He's going to mess up the shot.
0:20:41 > 0:20:45No, but science proved it - the ball was meant to go in the goal.
0:20:45 > 0:20:47Oh, you've got to be kidding, not again.
0:20:47 > 0:20:50He's gone back so he can re-take his original shot,
0:20:50 > 0:20:54and this time, it's gone in. Do you know the worst bit?
0:20:54 > 0:20:57You caused a rift in the space-time continuum
0:20:57 > 0:21:00and now there are three of you. Brilliant(!)
0:21:00 > 0:21:04And now it's time for...
0:21:08 > 0:21:12..featuring, as well as our teams, my glorious Snot Bots.
0:21:12 > 0:21:15They are brilliant. I've given them artificial intelligence,
0:21:15 > 0:21:17possibly a bit too much,
0:21:17 > 0:21:21because they have now started taking on human characteristics,
0:21:21 > 0:21:24including catching a cold.
0:21:24 > 0:21:26So I'm sorry about what you are standing in. It's not nice.
0:21:26 > 0:21:29But in there, you will find prize discs.
0:21:29 > 0:21:32Prizes include a voice warper, a weather station
0:21:32 > 0:21:37and a metal detector. But look out for these red and yellow herrings.
0:21:37 > 0:21:40You put one of these in your Snot Bots by accident,
0:21:40 > 0:21:44you'll lose a prize disc. You have some time to get
0:21:44 > 0:21:47as many of these prize discs into the Snot Bots as you can.
0:21:47 > 0:21:50Reds are in the lead, so you get a five-second head start.
0:21:50 > 0:21:53Yellows, you wait for the siren and then you start. Good luck.
0:21:53 > 0:21:56You have some time to get as many of the prize discs
0:21:56 > 0:21:59into the Snot Bots as you can. That time starts...now!
0:22:00 > 0:22:05There go the Reds, bursting into action, full of enthusiasm.
0:22:05 > 0:22:07The second siren sounds.
0:22:07 > 0:22:09Can the Yellows make up the time?
0:22:09 > 0:22:14I think yes might be the answer to that. They've got two discs.
0:22:14 > 0:22:17The teams are queuing up with the discs,
0:22:17 > 0:22:19but watch out for my sickly robot.
0:22:19 > 0:22:21Oh, no, he might be about to sneeze!
0:22:21 > 0:22:23Achoo!
0:22:23 > 0:22:28If only we had some king-size metal tissues for his drainpipe nose!
0:22:28 > 0:22:32Still unfazed, they continue about the age-old task
0:22:32 > 0:22:35of collecting prize discs from a manmade pool
0:22:35 > 0:22:38containing the snot of an allergy-ridden robot
0:22:38 > 0:22:40with one nostril.
0:22:43 > 0:22:45Another for the Reds.
0:22:45 > 0:22:50Georgina bides her some time waiting for the Snot Bot's mouth to open.
0:22:50 > 0:22:54And in it goes! Another disc for the Yellow team.
0:22:54 > 0:22:58Now Chris has found a yellow disc, which he's discarded.
0:22:58 > 0:23:01But what's this? Kevin sees the yellow disc
0:23:01 > 0:23:03and he's buried it under the gunge.
0:23:03 > 0:23:07That's not officially against the rules, but it's not very Blast Lab.
0:23:07 > 0:23:11This team clearly will do anything to win.
0:23:11 > 0:23:13It's a frantic pace the teams have set
0:23:13 > 0:23:15and they maintain it in the pool,
0:23:15 > 0:23:19displaying an almost obsessive attitude to the task before them.
0:23:23 > 0:23:28Uh-oh! Alan might be about to unleash another avalanche of snot.
0:23:28 > 0:23:30Oh!
0:23:30 > 0:23:33Tanith throws to Georgina. Great catch there.
0:23:33 > 0:23:37She's missed the Snot Bot, though. Let's see that again. It was close.
0:23:37 > 0:23:41Heartbreak in the pool today. Just glanced off.
0:23:43 > 0:23:49Some time is almost up. Georgina about to throw - it's in!
0:23:49 > 0:23:51In the nick of some time, she's done it.
0:23:51 > 0:23:54That is it! Time is up.
0:23:54 > 0:23:58Yellows, I think that last one was the closest thing I've ever seen.
0:23:58 > 0:24:00Fantastic! It went in.
0:24:00 > 0:24:03Now we must find out which team has won.
0:24:03 > 0:24:06We must count up the prize discs. lab rat, how many for the Yellows?
0:24:06 > 0:24:10Total for the Yellows...is...six.
0:24:10 > 0:24:13Six prizes. Well done. And for the Reds, what have we got?
0:24:13 > 0:24:16For the Reds we have three.
0:24:16 > 0:24:21That means the Yellows win! The Yellows win!
0:24:21 > 0:24:25And it seems they're quite pleased. Let's find out what you've won.
0:24:25 > 0:24:28Each of you will take home a super magnet kit.
0:24:28 > 0:24:32Brain trainers for each of you.
0:24:32 > 0:24:34Marine copter.
0:24:35 > 0:24:38Tomb of doom.
0:24:40 > 0:24:43Voice warper.
0:24:43 > 0:24:45And a metal detector.
0:24:45 > 0:24:46CHEERING
0:24:46 > 0:24:50Yeah! That's the atmosphere on this side of the tank. Really good!
0:24:50 > 0:24:52It's quieter over here.
0:24:52 > 0:24:54I can't imagine why(!)
0:24:54 > 0:24:57Tell you what we could do, just to pass the time -
0:24:57 > 0:24:59let's find out what you would have won.
0:24:59 > 0:25:02Each of you would have taken home a brain trainer.
0:25:02 > 0:25:03That would have been nice.
0:25:03 > 0:25:05A personal weather station.
0:25:05 > 0:25:06GROANING
0:25:06 > 0:25:07I know, it's... Oh!
0:25:07 > 0:25:10And, for each of you, a puzzle cube. Yeah.
0:25:10 > 0:25:12GROANING
0:25:12 > 0:25:14I know, I know. But here's the thing -
0:25:14 > 0:25:16it's not unusual to hear a bang in my lab,
0:25:16 > 0:25:19but this bang is bigger than most and it involves those prizes,
0:25:19 > 0:25:22because it is time for Bidet Goes Bang!
0:25:29 > 0:25:32Yellows, well done.
0:25:32 > 0:25:34It didn't look good for a while there,
0:25:34 > 0:25:37but then at the last minute, look at that. You'll be taking those home.
0:25:37 > 0:25:40Well done. The winners. Over here, it's the opposite story.
0:25:40 > 0:25:44That's the funniest thing, because from the start you were great,
0:25:44 > 0:25:47focused, and leading, and then lost. What happened?
0:25:47 > 0:25:50- It fell apart.- It all fell apart! That last game, it just...
0:25:50 > 0:25:55went to bits in front of you and now you're wearing horrible gunge.
0:25:55 > 0:25:57Chaps, I'm sorry, but to cheer you up,
0:25:57 > 0:26:00I thought it might be nice if you blow up all your prizes instead.
0:26:00 > 0:26:05OK. Right, follow me. It's time for...the walk of shame.
0:26:08 > 0:26:11Coming through. Coming through.
0:26:17 > 0:26:20Don't comfort me! I haven't lost!
0:26:28 > 0:26:30It's come to this, then, lads. It's come to this.
0:26:30 > 0:26:35Me, you, this plunger, an exploding bidet and your prizes.
0:26:35 > 0:26:37They are brought together and then blown apart.
0:26:37 > 0:26:41Lift the handle, please. Let's get on with it. We'll count them down.
0:26:41 > 0:26:42From five, if we're ready.
0:26:42 > 0:26:44Five, four,
0:26:44 > 0:26:47three, two, one!
0:26:50 > 0:26:52CHEERING
0:26:56 > 0:26:58It was a pleasure having you.
0:26:58 > 0:27:00You played well, and then you lost. Bad luck.
0:27:00 > 0:27:04It has been a good day. We used a cannon to fire balls at a goal,
0:27:04 > 0:27:07and, more importantly, shot lab rats with leaf blowers.
0:27:07 > 0:27:09That reminds me, we didn't get them down from the roof.
0:27:09 > 0:27:11I'll do it tomorrow. See you next time!
0:27:11 > 0:27:13Well done, guys.
