0:00:35 > 0:00:37Hello! Lab Rat, let me in!
0:00:37 > 0:00:41It's me, Richard. Let me in! Hello! Thank you.
0:00:46 > 0:00:48Discipline.
0:00:51 > 0:00:53Hi. I'm Richard Hammond.
0:00:53 > 0:00:55This is Blast Lab.
0:00:55 > 0:00:57CHEERING AND APPLAUSE
0:00:59 > 0:01:03Actually, this is my top secret laboratory that no-one must know
0:01:03 > 0:01:05the location of.
0:01:05 > 0:01:08If any friends of your claim to know the lab's whereabouts,
0:01:08 > 0:01:10seriously please inform us by sending a letter
0:01:10 > 0:01:16to Blast Lab, 1 Runkin Avenue, The Secret Forest, Kent, CT2... Oh!
0:01:16 > 0:01:18I've given that away, haven't I?
0:01:18 > 0:01:19I shall be inviting two teams
0:01:19 > 0:01:22to conduct scientific experiments.
0:01:22 > 0:01:25I'll be rewarding the best team with a host of prizes.
0:01:25 > 0:01:28Let's move quickly on and see what's coming up.
0:01:39 > 0:01:41CHEERING
0:01:41 > 0:01:45Because the work that goes on in this laboratory is so secret,
0:01:45 > 0:01:48I have a group of SAS men to protect it.
0:01:48 > 0:01:51Unfortunately, they spent their travel allowance on
0:01:51 > 0:01:53fairy princess comics again.
0:01:53 > 0:01:57The like the free gifts. So they couldn't afford their train tickets.
0:01:57 > 0:01:59Instead, I've roped in a deadly killing machine
0:01:59 > 0:02:03who has no need for train fares because she gets a free bus pass.
0:02:03 > 0:02:06It is my Ninja Nan.
0:02:06 > 0:02:09CHEERING AND APPLAUSE
0:02:15 > 0:02:19She may look a little fragile, but she is a fully-trained ninja.
0:02:24 > 0:02:27If you'd like to take your place in security, Nan!
0:02:27 > 0:02:31Nan! Nan! If you'd like to take your place in security please.
0:02:31 > 0:02:34Thank you very much. There she goes. You watch the speed here.
0:02:34 > 0:02:38You won't believe it. Look at that. Blink and you'll miss her.
0:02:38 > 0:02:40Wink, she'll think you're flirting.
0:02:40 > 0:02:42It's further than you'd think over there.
0:02:42 > 0:02:46Let's see how she's settled in. Nan? She's settled into security.
0:02:46 > 0:02:48Oh, there's a Lab Rat.
0:02:48 > 0:02:50She won't like that.
0:02:50 > 0:02:52And she didn't.
0:02:52 > 0:02:55Let's have a look at who's trying to get into the lab.
0:02:55 > 0:02:56CHEERING
0:02:56 > 0:03:00There you see. You applaud, that's all well and good.
0:03:00 > 0:03:04They say they're the Yellow Team. They could be anybody! Look at them!
0:03:04 > 0:03:08Let's make sure. I've got some security checks for you here.
0:03:08 > 0:03:12- Identify yourselves by names please. You are?- My name's Chantelle.
0:03:12 > 0:03:14- My name's Yeni. - My name's Eliana.
0:03:14 > 0:03:15Yeni, Eliana, Chantelle.
0:03:15 > 0:03:17That checks out. The talent here.
0:03:17 > 0:03:22It says your hidden talent is, Yeni, you can do hula-hooping.
0:03:22 > 0:03:25I'm guess that's what you've got the hula-hoop for.
0:03:25 > 0:03:26Demonstrate, please.
0:03:29 > 0:03:32Yeah, that's quite clever hula-hooping. Fair enough.
0:03:32 > 0:03:34We'll let you in. You're through security.
0:03:34 > 0:03:36CHEERING
0:03:39 > 0:03:44- We have our Yellow Team. Where are you guys from?- Milton Keynes.
0:03:44 > 0:03:47- We're Planet Glue.- You thought up a name! You don't need it.
0:03:47 > 0:03:49You're the Yellow Team.
0:03:49 > 0:03:50Welcome to Blast Lab.
0:03:50 > 0:03:53Lovely to have you here.
0:03:53 > 0:03:54Let's meet your opponents.
0:03:54 > 0:03:57CHEERING
0:03:57 > 0:03:59You guys claim to be the Red Team.
0:03:59 > 0:04:02Before I let you pass Ninja Nan and through security,
0:04:02 > 0:04:04we've got to carry out some checks.
0:04:04 > 0:04:07- Identify yourselves by names.- Josh.
0:04:07 > 0:04:09- Dylan. - Zak.- Josh, Dylan and Zak.
0:04:09 > 0:04:11Yeah, that checks out. Hidden talent here.
0:04:11 > 0:04:14It says you all know the rugby haka.
0:04:14 > 0:04:16- Do you?- Yes.
0:04:16 > 0:04:18Do it for us then, please.
0:04:21 > 0:04:25THEY PERFORM THE HAKA
0:04:32 > 0:04:35This is supposed to scare your enemies. It's scaring me.
0:04:35 > 0:04:39OK, I'll let you in. I'll let you in on the grounds of that!
0:04:39 > 0:04:41CHEERING
0:04:45 > 0:04:47Red Team. Terrifying. Where are you from?
0:04:47 > 0:04:51Brighton and we are the Seagulls.
0:04:51 > 0:04:54No, you're not the Seagulls. You're the Red Team.
0:04:54 > 0:04:56But welcome to Blast Lab.
0:04:56 > 0:04:59Both teams had better get ready for the first game.
0:04:59 > 0:05:02Get comfortable and settled in. We will play round one.
0:05:02 > 0:05:05To help us with that, here's a good friend of mine.
0:05:05 > 0:05:10He's got 15 GCSEs, two PhDs and an MOT. It is Oliver.
0:05:26 > 0:05:28CHEERING
0:05:28 > 0:05:32Oliver loves to spend his time roaming the world to collect fact
0:05:32 > 0:05:37for his fact nav system. And I've built it so it doesn't always work.
0:05:37 > 0:05:41Some of the facts are true, some of the facts are false.
0:05:41 > 0:05:44Oliver can tell which is which so I'm going to give
0:05:44 > 0:05:46each team a science fact.
0:05:46 > 0:05:49They'll tell me if they think it is right or wrong.
0:05:49 > 0:05:51If it is true, Oliver will do this.
0:05:51 > 0:05:54CAR HORN BLARES
0:05:54 > 0:05:57If it is false, Oliver will let us know by doing this.
0:05:57 > 0:05:59SHIP HORN BLARES
0:05:59 > 0:06:03OK teams, I'm going to ask each a question.
0:06:03 > 0:06:05Red team you are going first.
0:06:05 > 0:06:07Tell me if you think this is true or false.
0:06:07 > 0:06:11The Eiffel Tower sways by up to seven centimetres
0:06:11 > 0:06:14in the wind.
0:06:14 > 0:06:16Have a think, one of you
0:06:16 > 0:06:19might know something that might give you the answer.
0:06:19 > 0:06:21Audience what do you think? True or false?
0:06:21 > 0:06:26THEY SHOUT
0:06:27 > 0:06:31I reckon about 60/40 thinking false.
0:06:31 > 0:06:34- Is it true or false?- False.- You want to say it is false.
0:06:34 > 0:06:36Oliver, is it true or false?
0:06:36 > 0:06:39CAR HORN BLARES
0:06:39 > 0:06:41That means it is true. That means it is true.
0:06:41 > 0:06:43He knows the truth.
0:06:43 > 0:06:48The tower also leans very slightly in bright sunlight because one side
0:06:48 > 0:06:50of it will heat up and expand.
0:06:50 > 0:06:52Bad luck team, no points.
0:06:52 > 0:06:54Yellows, this is your chance to get ahead.
0:06:54 > 0:06:58Planet Saturn would dissolve in water.
0:06:58 > 0:07:01Have a think. Somebody might know something that is useful.
0:07:01 > 0:07:04Audience, what do we think? Is it true or false?
0:07:04 > 0:07:09THEY SHOUT
0:07:11 > 0:07:15Nearly everybody there thinks false. Nearly everybody here thinks true.
0:07:15 > 0:07:19Audience divided. You can't always go by what the audience think.
0:07:19 > 0:07:21- Have we come to a conclusion?- False.
0:07:21 > 0:07:24You think it is false? Oliver is it true or false?
0:07:24 > 0:07:25SHIP HORN BLARES
0:07:25 > 0:07:28It is false.
0:07:28 > 0:07:31That's a point to the yellow team, well done. Saturn is less dense than
0:07:31 > 0:07:34water which means it would float
0:07:34 > 0:07:37if you could find a bath big enough to put it in.
0:07:37 > 0:07:40Let's have the final question, this one works differently.
0:07:40 > 0:07:43I won't ask you to tell me whether it's true or false.
0:07:43 > 0:07:47I'm going to ask you to actually answer the question.
0:07:47 > 0:07:50Both get the same question and you write your answer down.
0:07:50 > 0:07:54I'll give the point to the person who is nearest the correct answer.
0:07:54 > 0:07:58What was the coldest temperature ever recorded on earth?
0:07:58 > 0:08:01In degrees Celsius, the coldest temperature recorded on earth.
0:08:01 > 0:08:03Have a good think teams.
0:08:03 > 0:08:06Audience, anybody got a clue? Put your hand up.
0:08:06 > 0:08:07I'll come and talk to you.
0:08:07 > 0:08:14It is a boot but it is also a microphone.
0:08:14 > 0:08:16What d'you think?
0:08:16 > 0:08:18You wouldn't know would you?
0:08:18 > 0:08:19Probably minus 90 degrees.
0:08:19 > 0:08:22Minus 90 Degrees, talk to the boot, what do you think?
0:08:22 > 0:08:24Minus 45.
0:08:24 > 0:08:27Minus 45, quite a range straightaway.
0:08:27 > 0:08:32- Minus 15.- Minus 90 to minus 15, quite a range.
0:08:32 > 0:08:33Yes, what do you think?
0:08:33 > 0:08:38- Minus 167.- That is very precise young man.
0:08:38 > 0:08:43Have you got inside information on this one? Are you a weatherman?
0:08:43 > 0:08:45- Yes.- Do you like my invention?- Yes.
0:08:45 > 0:08:47- You do? Do you want to buy it?- Yes.
0:08:49 > 0:08:52You're just toying with me, I know that, it is not true.
0:08:52 > 0:08:55I'm going to find out what the teams think.
0:08:55 > 0:08:59If you'd like to turn your boards round. Reds, minus 50.
0:08:59 > 0:09:05Yellows, that looks like minus 25,000 which is really nippy.
0:09:05 > 0:09:07Let's find out.
0:09:07 > 0:09:12The temperature was minus 89.4 degrees recorded in
0:09:12 > 0:09:18Vostok weather station in Antarctica in 1983. Reds, you get the point.
0:09:18 > 0:09:20CHEERING
0:09:22 > 0:09:24That would have been cold. Imagine the hat
0:09:24 > 0:09:26you'd have had to wear for that.
0:09:26 > 0:09:31Right, that means we've finished with a point each. 1-1.
0:09:43 > 0:09:45CHEERING
0:09:45 > 0:09:48That's all to come, right now this is mini science.
0:09:48 > 0:09:52I shall challenge my scientists to conduct experiments using
0:09:52 > 0:09:59household objects with the help of my 65 year old teacher, Mini Miss.
0:09:59 > 0:10:02I thought it was a good idea, Miss.
0:10:05 > 0:10:07- Hello, Miss.- Hello, Richard. - I should explain,
0:10:07 > 0:10:10I invented a time machine to bring back my science teacher.
0:10:10 > 0:10:14And may have made a mistake as you ended up as a ten-year-old.
0:10:14 > 0:10:18- Hurry up, I want to set them a test. - What are we doing today?
0:10:18 > 0:10:22We will look at the strength and force of weight distribution.
0:10:22 > 0:10:24That sounds technical. How will we do that?
0:10:24 > 0:10:27Teams are going to playing a game called anti-gravity grip.
0:10:27 > 0:10:31We're going to attach a coat hanger to a platform using Velcro.
0:10:32 > 0:10:33The teams have to take it in turns to
0:10:33 > 0:10:36clip on household objects to the coat hanger.
0:10:36 > 0:10:40The team who eventually detaches
0:10:40 > 0:10:42the coat hanger from the Velcro loses the game.
0:10:42 > 0:10:47This is the coat hanger and this is the stuff that will attach it.
0:10:47 > 0:10:49This goes on here.
0:10:49 > 0:10:51Like that I believe.
0:10:51 > 0:10:54There we go. As they add more and
0:10:54 > 0:10:57more weight to it, it is going to be quite nail-biting this.
0:10:57 > 0:11:01Yes, it is. It takes skill and nerve to play this game.
0:11:01 > 0:11:04Teams, I'm going to give you a hint. Mini Miss gave us a clue
0:11:04 > 0:11:07when she said it is about weight distribution.
0:11:07 > 0:11:13As you put things on here, try to add them nearer to the centre.
0:11:13 > 0:11:16That will mean the weight is distributed across there.
0:11:16 > 0:11:19That means it will hold it up. This will get harder as you get
0:11:19 > 0:11:22more things attached to it, but as things get further out,
0:11:22 > 0:11:26the weight is concentrated in one area and that will be it.
0:11:26 > 0:11:30It will fail. That is a hint I have given you there, is that OK, Miss?
0:11:30 > 0:11:32- Yes.- I've never done that before. That's a hint.
0:11:32 > 0:11:35You are competing head-to-head on this one.
0:11:35 > 0:11:39It is a draw on the scores so we will have to decide who goes first.
0:11:39 > 0:11:41Lab rats, if you tidy that ready for us.
0:11:41 > 0:11:45To do that, we shall draw Blast Lab pens.
0:11:45 > 0:11:47If you'd like to pick first yellows.
0:11:49 > 0:11:52Reds, that means you get the short pen.
0:11:52 > 0:11:55- Yellows you get the decision. First or second?- First.
0:11:55 > 0:11:59Yes, that's the best way to do it in this case.
0:11:59 > 0:12:02I would advise you to have a chat and have a think.
0:12:02 > 0:12:05Look at the objects. I will give you a bit of time
0:12:05 > 0:12:08have to look at the objects and think about how they work.
0:12:08 > 0:12:11If you look closely, on one side there are tiny hooks.
0:12:11 > 0:12:16On the other, there are tiny loops.
0:12:16 > 0:12:19Obviously, the hooks catch on the loops and grip.
0:12:19 > 0:12:22If we had one of those hooks and one of those loops, it wouldn't be able
0:12:22 > 0:12:27to hold anything but by having lots of them, we can spread the weight.
0:12:27 > 0:12:28They share the weight between
0:12:28 > 0:12:32them and so these can support 20kg per square centimetre.
0:12:32 > 0:12:37- Have we had a chat and a think?- Yes. - Yellow team you are going first.
0:12:40 > 0:12:42You've gone for the teddy bear. Why?
0:12:42 > 0:12:44Because it is the lightest.
0:12:44 > 0:12:46OK, away you go then. Attach it.
0:12:48 > 0:12:52There you go, the first object is on.
0:12:52 > 0:12:53The first object is there.
0:12:53 > 0:12:57A ripple of applause, we are quite tense in here.
0:12:57 > 0:12:59It is quite nail-biting.
0:13:02 > 0:13:05- Red team have you made your decision?- The rugby ball..
0:13:05 > 0:13:10- The rugby ball? Why?- We have a feeling it is going to save us.
0:13:10 > 0:13:13Right, carry on then.
0:13:14 > 0:13:16Tense moment audience. Tense moment.
0:13:19 > 0:13:23Here we go. Well done, Dylan.
0:13:23 > 0:13:28You can see weight distribution just like this in action when
0:13:28 > 0:13:30circus performer's lie on a bed of nails
0:13:30 > 0:13:34without getting hurt and hold a big weight on top of them.
0:13:34 > 0:13:37It is because their weight is spread over all the nails.
0:13:37 > 0:13:40If they were to lie on just one nail, all of their weight
0:13:40 > 0:13:42would be on that and go through them.
0:13:45 > 0:13:48Have we made our decision? What are we going for?
0:13:48 > 0:13:53- Tennis racket.- Go for whatever you want, it is your choice.
0:13:55 > 0:14:00I can't watch, this is terrifying.
0:14:02 > 0:14:05Take your time, we are not going to hurry you.
0:14:07 > 0:14:09Don't look to me for help, yellow.
0:14:09 > 0:14:12You are on your own, Chantelle.
0:14:12 > 0:14:16Here we go.
0:14:16 > 0:14:18Well done.
0:14:18 > 0:14:20Nice one, Chantelle.
0:14:20 > 0:14:23Reds, that means the problem is now back with you.
0:14:27 > 0:14:30Weight distribution like this is important in building.
0:14:30 > 0:14:32If you think of suspension bridges
0:14:32 > 0:14:35the weight is spread between all the cables.
0:14:35 > 0:14:37If they use just one, it would snap.
0:14:37 > 0:14:41We have got three objects up there successfully.
0:14:41 > 0:14:44Come on, Reds. What are you going to do?
0:14:44 > 0:14:49Who's going to attach it? Zack? Zack, that's a rotten job to get.
0:14:49 > 0:14:50Good luck to you.
0:14:53 > 0:14:57Here we go. Oh, shh, shh, shh.
0:14:57 > 0:15:01Right, the clips on, now to see if it will take the weight.
0:15:01 > 0:15:03Come on Zack, come on Zack, come on
0:15:06 > 0:15:08Zack, come on, come on, good luck, good luck.
0:15:11 > 0:15:12Come on Zack. Oh, yes! Well done!
0:15:12 > 0:15:14Oh, Yellows!
0:15:16 > 0:15:20You see weight distribution actually just like this in shin guards when
0:15:20 > 0:15:23you're playing football because all they do is
0:15:23 > 0:15:26spread the impact of the ball, or if somebody kicks you,
0:15:26 > 0:15:30they spread it across the whole of the pad so it feels less painful.
0:15:30 > 0:15:35That's weight distribution, just like this. Yellows, nervous?
0:15:35 > 0:15:38- Who is volunteering to attach it? - Eliana.
0:15:38 > 0:15:41Eliana, good luck. Good luck, good luck, good luck.
0:15:41 > 0:15:43This, now is.
0:15:50 > 0:15:51Well, the hook's on.
0:15:52 > 0:15:53I don't believe it!
0:15:53 > 0:15:55CHEERING
0:15:58 > 0:16:01- How you feeling then lads?.- Decided. - You've decided.
0:16:01 > 0:16:04You're not messing about, now.
0:16:04 > 0:16:06They are playing mean. Right, OK.
0:16:09 > 0:16:10Josh, good luck. Good luck.
0:16:10 > 0:16:13Think about weight distribution.
0:16:13 > 0:16:16He's making his move.
0:16:16 > 0:16:19He was thinking about this like it was chess, then.
0:16:19 > 0:16:21Woah. I can hear it going.
0:16:23 > 0:16:28He's changed his mind. Look at that. Woah-ho-ho.
0:16:28 > 0:16:30Woah!
0:16:31 > 0:16:33- We're gonna lose!- Yes!
0:16:37 > 0:16:39- We're gonna lose!- That's not the attitude.
0:16:39 > 0:16:42Think about weight distribution. Think about it.
0:16:51 > 0:16:54Aw! Yellows. Bad luck. What could you do with that?
0:16:54 > 0:16:58That means red team are the winners.
0:16:58 > 0:17:00CHEERING
0:17:00 > 0:17:02It takes the score to 2-1.
0:17:02 > 0:17:06Bad luck yellows. That was a good game. Thank you, miss.
0:17:06 > 0:17:09All this talk about weight distribution has got me thinking.
0:17:09 > 0:17:14What if I use it on one of my lab rats?
0:17:14 > 0:17:16My big idea this week is to create
0:17:16 > 0:17:19a human spider that can climb up a wall but first
0:17:19 > 0:17:25a demonstration of how rubbish man is at climbing up vertical surfaces.
0:17:26 > 0:17:271, 2, 3...
0:17:27 > 0:17:31# My baby don't mess around because she loves me so
0:17:31 > 0:17:34# And this I know for sure
0:17:36 > 0:17:38# But does she really wanna
0:17:38 > 0:17:40# But can't stand to see me walk out the door... #
0:17:40 > 0:17:44He is pretty useless, which is probably why
0:17:44 > 0:17:47we invented stairs and ladders.
0:17:47 > 0:17:51A spider could whizz up a wall in seconds but what does a spider
0:17:51 > 0:17:54have that a human doesn't?
0:17:54 > 0:17:58Spiders have a number of tiny claws on the end of their legs.
0:17:58 > 0:18:00When they climb walls, these claws
0:18:00 > 0:18:03hook onto the small ridges and cracks in the wall's surface.
0:18:03 > 0:18:06A bit like the way Velcro works.
0:18:06 > 0:18:10So, if we had a suit made of one side of Velcro and a wall made of
0:18:10 > 0:18:14the other, then could we climb it?
0:18:17 > 0:18:20Obviously, this is not something to try at home.
0:18:20 > 0:18:24So, to test my theory, my loyal lab rats have
0:18:24 > 0:18:29constructed a ten metre-high wall covered in thousands of loops and
0:18:29 > 0:18:34I have designed a special suit of hooks for a lab rat to wear but
0:18:34 > 0:18:40this isn't a challenge for any old lab rat what we need is Spider rat.
0:18:40 > 0:18:43# Spiderman, Spiderman, does whatever a spider can
0:18:43 > 0:18:47# Spins a web any size can't you see just like eyes
0:18:47 > 0:18:51# Look out, here comes the Spiderman... #
0:18:51 > 0:18:56His superhero suit will allow him to climb up a vertical wall. We hope.
0:18:56 > 0:19:02Hold the experiment there. I think there's an extra point in this.
0:19:02 > 0:19:07Teams, will he manage to climb to the top of the wall or not?
0:19:07 > 0:19:13- Audience, What do you think?- Depends how heavy he is against the wall.
0:19:13 > 0:19:15True, it is all about weight,
0:19:15 > 0:19:18spreading it between all of those different hoops and loops.
0:19:18 > 0:19:20- What d'you think?- Maybe the loops.
0:19:20 > 0:19:24I think, the audience generally quite unsure on this one.
0:19:24 > 0:19:28Anybody got an idea? You looked like you were going to put your hand up?
0:19:28 > 0:19:30I don't think he will because
0:19:30 > 0:19:34- the gravity will try to pull him down.- The gravity tends to do that.
0:19:34 > 0:19:37He won't go as high up as he plans to go.
0:19:37 > 0:19:38You think what, may be part way?
0:19:38 > 0:19:42Yeah. Well, it really depends on the wall.
0:19:42 > 0:19:47The audience are a bit unsure on this one. What do we think teams?
0:19:47 > 0:19:52- Have we both made up our minds? - Yes, yes.- OK. Reds, will they do it?
0:19:52 > 0:19:55- Yes, yes.- You think he will. Yellows, d'you think he will?
0:19:55 > 0:20:01- No.- Reds think lab rat will make it to top, yellows think not.
0:20:01 > 0:20:05There's only one way to find out. Get on with the experiment.
0:20:05 > 0:20:08OK, spider rat, do your thing.
0:20:10 > 0:20:14The suit has stuck to the wall. Now for the climb.
0:20:14 > 0:20:22I said climb. No, just lifting your feet off the ground isn't climbing.
0:20:23 > 0:20:24Oh dear.
0:20:24 > 0:20:29Bit more energy this time. Get up there.
0:20:29 > 0:20:30Yes, he's climbing.
0:20:35 > 0:20:38No, he isn't. Come on, you're not trying.
0:20:46 > 0:20:49That's really not very super, is it?
0:20:49 > 0:20:51Spiderman would not be impressed.
0:20:54 > 0:20:57Last try. Backwards doesn't work.
0:21:03 > 0:21:04Hang on, he's half way up.
0:21:04 > 0:21:10Oh, apparently he cheated. So he can stick, but not climb.
0:21:10 > 0:21:13The world's least mobile super hero.
0:21:13 > 0:21:17Thank you, spider rat. You're a complete and utter failure.
0:21:17 > 0:21:18CHEERING
0:21:18 > 0:21:21So that brings the score back to two points each.
0:21:21 > 0:21:24The lab rat didn't make it to the top of the wall because every time
0:21:24 > 0:21:29his body moved there weren't as many hooks and loops coming together
0:21:29 > 0:21:33and spreading his weight, it was still about weight distribution.
0:21:33 > 0:21:36Teams, with your scores you better get off.
0:21:36 > 0:21:38It's time to get ready for the Messy Messy Mess Test.
0:21:38 > 0:21:40So into your protective suits.
0:21:40 > 0:21:42It's time then for us to move on.
0:21:42 > 0:21:47They got it into their heads that they can do this.
0:21:47 > 0:21:51I don't like to tell them it's not worth trying because
0:21:51 > 0:21:56I like watching them fail. Let's move to the Messy Messy Mess Test.
0:21:58 > 0:22:00Which today is in the septic tank.
0:22:00 > 0:22:04Don't ask me what's in there. Not because I don't know but because
0:22:04 > 0:22:06thinking about it makes me feel sick.
0:22:06 > 0:22:09There are some creatures that like it in there. Things like rats.
0:22:09 > 0:22:14So if you do see anything do please scream.
0:22:14 > 0:22:16I probably will. This is the game.
0:22:16 > 0:22:19Hidden in the tank that you are standing in are discs.
0:22:19 > 0:22:21Some of them are like this one.
0:22:21 > 0:22:25Duds. But the ones you're after are like these. They feature
0:22:25 > 0:22:30your team's colour and the names of prizes, things like MP3 player.
0:22:30 > 0:22:33Maybe a kitchen chemistry set, maybe some hulk smash hands.
0:22:33 > 0:22:36Your job as teams is to find as many as you can.
0:22:36 > 0:22:38Lab rat, you can get out now. Set those in and get out.
0:22:38 > 0:22:41Your job is to find as many of those prized discs as you can
0:22:41 > 0:22:43and get them in these baskets.
0:22:43 > 0:22:45One for the yellow team, one for the red team.
0:22:45 > 0:22:48The winning team will be the one with the most prize discs
0:22:48 > 0:22:51into the baskets and you get to take them home.
0:22:51 > 0:22:54The losing team will have to blow yours up.
0:22:54 > 0:22:59The score right now is a draw. It is 2-2 so nobody starts first.
0:22:59 > 0:23:02Both teams when you hear the siren sound, you start.
0:23:02 > 0:23:05You've got some time to get as many
0:23:05 > 0:23:11prize discs into these baskets and that sometime starts now.
0:23:14 > 0:23:18Both teams not wasting any time as they immediately start the search
0:23:18 > 0:23:20for prizes in perfect unison.
0:23:20 > 0:23:23They are off the mark now with a prize each.
0:23:23 > 0:23:29But it's the reds who've taken the initiative as the red-prize haul
0:23:29 > 0:23:34grows, then grows some more. Not looking good for the yellows here.
0:23:37 > 0:23:41Can you believe I've forgotten to warn them that sometimes there's
0:23:41 > 0:23:46more of whatever that stuff is that they're in dropping down.
0:23:46 > 0:23:50But it sometimes brings prize discs with it so it's a good thing.
0:23:50 > 0:23:52Yeah, it's a good thing.
0:23:52 > 0:23:58It smells worse than it looks. A second siren sounds, the goo flows.
0:23:58 > 0:24:03Prizes are falling. What more could the young scientists ask for?
0:24:03 > 0:24:08The team 's have swapped sides of the tank in their search for prizes.
0:24:08 > 0:24:11Clever thinking, A for effort, doesn't actually seem to be
0:24:11 > 0:24:14helping much, though.
0:24:14 > 0:24:17CHEERING
0:24:19 > 0:24:20SIREN WAILS
0:24:20 > 0:24:25Another siren. We know what that means, more goo and more prizes.
0:24:25 > 0:24:28No, we're not actually watching a slow-motion replay, the teams
0:24:28 > 0:24:31really are moving that slow.
0:24:31 > 0:24:33Are they tired? Are they stuck in the goo?
0:24:33 > 0:24:37Don't they realise sometime won't last for ever?
0:24:37 > 0:24:41- Who cares?- Four, three, two, one.
0:24:43 > 0:24:47OK, Time is up. Time is up. Both teams, that is the end of that game.
0:24:47 > 0:24:51Lab rats, count them up let's have a look and discover which team won.
0:24:51 > 0:24:53First of all, reds, how many have they got?
0:24:53 > 0:24:55Four for reds. Yellow have got how many?
0:24:55 > 0:24:59Three. That means reds are the winners.
0:24:59 > 0:25:01CHEERING
0:25:01 > 0:25:03Well done, reds. Congratulations.
0:25:03 > 0:25:06Let's have a look at what you've won. Are you ready?
0:25:06 > 0:25:09Kitchen chemistry set. You'll each take one of those home.
0:25:09 > 0:25:14An MP3 player. A science magic set, one of those each.
0:25:14 > 0:25:16A lunar eclipse bedroom light.
0:25:16 > 0:25:19Red team, those are your prizes!
0:25:19 > 0:25:22CHEERING
0:25:22 > 0:25:23Well done. And now, the yellows.
0:25:23 > 0:25:27Let's have a look at what you would have won. Robo-Bugs.
0:25:27 > 0:25:29- Ah!- A chemistry set.- Ah!
0:25:29 > 0:25:33- And a science magic set.- Ah!
0:25:33 > 0:25:38Unfortunately, there is a scientific protocol that we must adhere to.
0:25:38 > 0:25:41I have it here in my lab coat at all times.
0:25:41 > 0:25:44Any person or persons in receipt of prize or prizes that they have not
0:25:44 > 0:25:48lawfully obtained or won must have their prize or
0:25:48 > 0:25:52prizes taken from them to destroyed with the use of an exploding bidet.
0:25:52 > 0:25:55Which means it's time for Bidet Goes Bang!
0:26:04 > 0:26:07It is that moment in Blast Lab where one team look happy.
0:26:07 > 0:26:11The reds here with all these things they're taking home.
0:26:11 > 0:26:13Well done for winning, red team.
0:26:13 > 0:26:18The other team, today it's the yellows, looking not quite so happy.
0:26:18 > 0:26:22I'm sorry, yellows. One team's got to win, one team's got to lose.
0:26:22 > 0:26:23What went wrong in that last game?
0:26:23 > 0:26:27- I think we weren't fast enough. - It was hard. It's a hard game.
0:26:27 > 0:26:29You have to blow your prizes up.
0:26:29 > 0:26:33- Who's going to push the plunger? - All of us.- Teamwork.
0:26:33 > 0:26:38If you could lift the plunger for us. Lift the plunger up.
0:26:38 > 0:26:40Don't push it down yet. There'll be an explosion.
0:26:40 > 0:26:45We're going to give you a countdown. Here we go.
0:26:45 > 0:26:49Five, four, three, two, one, go!
0:26:49 > 0:26:52EXPLOSION
0:26:53 > 0:26:57There you go. Today we have learnt that when weight is spread across
0:26:57 > 0:27:01a wider area, much heavier objects can be suspended. Did we do that
0:27:01 > 0:27:05by nobly delving through hundreds of in-depth scientific research papers?
0:27:05 > 0:27:08It was more a case of sticking stuff to other stuff.
0:27:08 > 0:27:10It's been fun! See you next time!
0:27:10 > 0:27:12CHEERING
0:27:15 > 0:27:20Blast Lab was recorded before a live studio audience. No lab rat was
0:27:20 > 0:27:25harmed during the filming, though I did try my hardest.
0:27:25 > 0:27:29# I'll be the one to show you the way
0:27:29 > 0:27:32# You'll be the one to always complain
0:27:32 > 0:27:35# Three in the morning come a bang bang... #
