0:00:34 > 0:00:37OK, left a bit. Right a bit.
0:00:37 > 0:00:41That's it! Move your way gently across like that. Mind the pylon.
0:00:41 > 0:00:50- BUZZING - Don't get any closer! Ohh! Yeah, OK. My remote-control parachute.
0:00:50 > 0:00:54Perfect - lacks just one thing, as it turns out. Control!
0:00:54 > 0:00:59Back to the drawing board. Well, go on, back to the drawing board.
0:00:59 > 0:01:02I'm Richard Hammond. This is my Blast Lab!
0:01:02 > 0:01:03CHEERING
0:01:05 > 0:01:11Now, I have invited two teams of young scientists into the lab to
0:01:11 > 0:01:13take part in scientific challenges.
0:01:13 > 0:01:18The successful team will win prizes. The unsuccessful team will also win
0:01:18 > 0:01:23prizes, but they'll have to blow them up. Let's see what's in store.
0:01:33 > 0:01:36Now, what with this...
0:01:36 > 0:01:40What with this place being a top secret underground lab,
0:01:40 > 0:01:44normally it's guarded round the clock by a crack SAS team.
0:01:44 > 0:01:49Unfortunately, they all stayed up watching Finding Nemo last night,
0:01:49 > 0:01:53and got scared by the sharks, and were too scared to come in today.
0:01:53 > 0:01:58But don't worry, we've got a woman who is scared of nothing,
0:01:58 > 0:02:03apart from getting toffee stuck in her false teeth. She's my Ninja Nan!
0:02:03 > 0:02:04APPLAUSE
0:02:12 > 0:02:17Ninja Nan, thank you very much for standing in. Thank you.
0:02:17 > 0:02:21I know she looks fragile, but she is a trained ninja.
0:02:21 > 0:02:23POW! THWACK! BAM!
0:02:26 > 0:02:30Er, Nan, if you'd like to take your place... Nan! NAN!
0:02:30 > 0:02:33If you'd like to take your place in security, thank you.
0:02:33 > 0:02:38Great to have you here. We're all safe. We all feel much safer.
0:02:38 > 0:02:39There she goes.
0:02:39 > 0:02:43Look at her move. You can tell! That ninja gracefulness.
0:02:43 > 0:02:49She's so hard she sprinkles drawing pins on her porridge in the morning.
0:02:49 > 0:02:51Nan, are you there? Oh, there she is.
0:02:51 > 0:02:54I notice she's wearing her slippers today.
0:02:54 > 0:02:59After a hard day's kicking, even a ninja's feet need a little rest.
0:02:59 > 0:03:02Right, she's settled. Time to meet the people
0:03:02 > 0:03:05trying to get into my lab today. Let's have a look!
0:03:05 > 0:03:07APPLAUSE AND CHEERING
0:03:09 > 0:03:13We're all getting excited. We don't know yet.
0:03:13 > 0:03:17We've got to make absolutely sure. Lots of people try and get into my
0:03:17 > 0:03:19lab, so there are security checks.
0:03:19 > 0:03:23- OK, identify yourselves, first of all. You are?- Tom.
0:03:23 > 0:03:24- Leanne.- Martin.
0:03:24 > 0:03:26Tom, Leanne and Martin.
0:03:26 > 0:03:29Well, that checks out with the form.
0:03:29 > 0:03:32Under hidden talent, Martin, I've got your name.
0:03:32 > 0:03:36Martin, it says you're going to tell a very funny joke.
0:03:36 > 0:03:38If it's 6/10, we'll let you in.
0:03:38 > 0:03:41OK. Why didn't Cinderella make the football team?
0:03:41 > 0:03:46Why did... I don't know, why didn't Cinderella make the football team?
0:03:46 > 0:03:50- Because her coach kept turning into a pumpkin!- Woah! I don't know,
0:03:50 > 0:03:52Is that six? Yeah, it probably is.
0:03:52 > 0:03:55You're cleared. Come on in, please.
0:03:55 > 0:03:57APPLAUSE
0:04:00 > 0:04:02That was a bit borderline,
0:04:02 > 0:04:06but I believe you are the Yellows. We can't let just anybody in!
0:04:06 > 0:04:10We've to be careful with security. Where have you come from?
0:04:10 > 0:04:14ALL: Essex! And we're The Rolling Reactions!
0:04:14 > 0:04:16You came up with your own team name!
0:04:16 > 0:04:20You needn't have bothered, you're the Yellow team and that's final.
0:04:20 > 0:04:22Let's meet the guys who
0:04:22 > 0:04:26claim to be the team that you're going to be playing against, OK?
0:04:26 > 0:04:29- APPLAUSE - The supposed Red Team. Yes, yes. Listen,
0:04:29 > 0:04:32that's all well and good. They could be anybody.
0:04:32 > 0:04:36- Identify yourselves by name, please.- Ryan.- Jack.- Jacob.
0:04:36 > 0:04:40Ryan, Jack, Jacob. That's what it says on the form.
0:04:40 > 0:04:44It says all of you are going to demonstrate a hidden talent.
0:04:44 > 0:04:46- What are you going to do? - Ju jitsu.- Bless you.
0:04:46 > 0:04:49- Hang on, is that a sort of fighting?- Yes.
0:04:49 > 0:04:51Don't move a muscle!
0:04:51 > 0:04:54Lab Rats, you're going to have to make Ninja Nan safe.
0:04:54 > 0:05:00There. she'll never cross that line. You'll be fine. OK, if you can
0:05:00 > 0:05:04demonstrate your sneeze fighting we'll let you through.
0:05:04 > 0:05:06One, two, three, ya!
0:05:06 > 0:05:09Well, we're not quaking with fear!
0:05:09 > 0:05:13But I think we'll believe you. You're cleared through security.
0:05:13 > 0:05:15Come into the Blast Lab.
0:05:15 > 0:05:17CHEERING
0:05:18 > 0:05:21OK, you are the Red Team. Where have you come from?
0:05:21 > 0:05:25Essex! And we're Team Fireblast!
0:05:25 > 0:05:27Another name, which you didn't need!
0:05:27 > 0:05:32You're the Red Team. Red and Yellow Team, go get ready for Round One.
0:05:32 > 0:05:35To help us out with that, I'd like to introduce a friend of
0:05:35 > 0:05:39mine who is better at handling science problems than he is
0:05:39 > 0:05:41at handling corners. It is Oliver!
0:05:57 > 0:05:59I know! What a machine!
0:05:59 > 0:06:02CHEERING
0:06:02 > 0:06:07Now, when I fitted Oliver's state-of-the-art Fact Nav system,
0:06:07 > 0:06:11I was very careful to follow the instruction manual to the letter.
0:06:11 > 0:06:17Unfortunately, it was all written in Greek, so it doesn't actually work
0:06:17 > 0:06:21that well. Not all its facts are correct, so I'm going to
0:06:21 > 0:06:25need our two teams to tell me which are true and which are false.
0:06:25 > 0:06:29When they've given us their view, Oliver will give us the truth.
0:06:29 > 0:06:31If it is true, he'll say this.
0:06:31 > 0:06:33HONKING AND TOOTING
0:06:34 > 0:06:37And if it's false, he'll say this.
0:06:37 > 0:06:38FOG HORN BLASTS
0:06:38 > 0:06:44OK, teams, this is your first chance to earn a point. Everybody OK?
0:06:44 > 0:06:48Right, Reds, you're going first. Here is your science fact.
0:06:48 > 0:06:52Listen carefully and tell me whether it's true or false.
0:06:52 > 0:06:54A bolt of lightning is powerful enough
0:06:54 > 0:06:58to toast 100,000 pieces of bread.
0:06:58 > 0:07:01Is that true or false? Have a chat.
0:07:01 > 0:07:06Have a talk and a think. Audience, do you think that's true or false?
0:07:06 > 0:07:07ALL: TRUE!
0:07:09 > 0:07:13The audience then going for true. Reds, have you made your mind up?
0:07:13 > 0:07:17- Yes.- I mean, you can listen to the audience or not. It's up to you.
0:07:17 > 0:07:21Jack, are you being spokesperson? Is it true or false?
0:07:21 > 0:07:24- True.- Oliver, is it true or false?
0:07:24 > 0:07:25HONKING AND TOOTING
0:07:25 > 0:07:29It's true! That's a point to the Red Team. It can indeed.
0:07:29 > 0:07:34That's an awful lot of toast, obviously, 100,000 slices,
0:07:34 > 0:07:37but a lightning bolt isn't short on energy.
0:07:37 > 0:07:41It typically contains about five billion joules of energy.
0:07:41 > 0:07:45That's a lot! One typical strike could power a 1,000 watt
0:07:45 > 0:07:48toaster for 84,000 minutes, which would be time enough
0:07:48 > 0:07:52to toast that much toast, if you were wanting to do that.
0:07:52 > 0:07:57I'll ask the Yellows their question. This is your science fact.
0:07:57 > 0:08:00Tell me whether this is true or false.
0:08:00 > 0:08:05Cumulonimbus clouds can be twice as high as Mount Everest.
0:08:05 > 0:08:08Have a chat, have a think, work it out. You never know.
0:08:08 > 0:08:11Audience, what do we think, true or false?
0:08:13 > 0:08:18- False!- Nearly all of the audience going for false, but,
0:08:18 > 0:08:22you can't always believe the audience. What do we reckon?
0:08:22 > 0:08:24- False.- False?
0:08:24 > 0:08:27Everybody in agreement? That's your final answer.
0:08:27 > 0:08:31- OK, Oliver, is it true or false? - HONKING AND TOOTING
0:08:31 > 0:08:34It's true, which means no point for you there.
0:08:34 > 0:08:36If you were wondering,
0:08:36 > 0:08:39apparently Cumulonimbus clouds can be approximately six miles
0:08:39 > 0:08:41across and 11 miles high.
0:08:41 > 0:08:45That's quite a lot of cloud! Right, your third question.
0:08:45 > 0:08:50I want an actual answer to this, OK, teams? OK? That's why you have
0:08:50 > 0:08:53the boards to write your answers on. Here's the question.
0:08:53 > 0:08:56How many years would it take
0:08:56 > 0:08:59to cross our galaxy at the speed of light?
0:08:59 > 0:09:03I'll give the point to the team that gets nearest the answer.
0:09:03 > 0:09:05You don't have to be bang on.
0:09:05 > 0:09:09How many years to cross our galaxy at the speed of light?
0:09:09 > 0:09:13Audience, anybody got any theories? You'll have noticed this.
0:09:13 > 0:09:17I can see you were impressed. It looks like a traffic cone,
0:09:17 > 0:09:22but using science here in the Blast Lab, I've made our microcone!
0:09:22 > 0:09:26Because it's a microphone combined with a cone.
0:09:26 > 0:09:30It's cunningly hidden in the end. You're not impressed,
0:09:30 > 0:09:34- are you? No, well, OK. What do you think is the answer?- 80.
0:09:34 > 0:09:38Anybody else got any theories how long it would take?
0:09:38 > 0:09:41- 100?- OK, anybody over here got a clue?
0:09:41 > 0:09:44Anybody vary differently from that answer?
0:09:44 > 0:09:48- 50.- OK, teams, have you both written down your answer?
0:09:48 > 0:09:52Reds have agreed. They're answer is written down.
0:09:52 > 0:09:55Yellows, we've got one written down.
0:09:55 > 0:09:59OK, turn round your boards and we'll have a look at what you've written.
0:09:59 > 0:10:03Right, Reds, is that 101,000?
0:10:03 > 0:10:06That's 101,000 years.
0:10:06 > 0:10:10That's quite a precise answer! Where did the 1,000 come from?
0:10:10 > 0:10:12- Well, the galaxy's big.- It is!
0:10:12 > 0:10:16It is a whacking great big thing, I agree. It is huge.
0:10:16 > 0:10:19OK, Yellows, you've gone for 800 years.
0:10:19 > 0:10:24Quite a disparity between these two answers. 101,000, and 800.
0:10:24 > 0:10:26Well, the real answer is...
0:10:26 > 0:10:31100,000 years, which means very close indeed for the Reds.
0:10:31 > 0:10:33The point goes to the Red Team!
0:10:33 > 0:10:35APPLAUSE AND CHEERING
0:10:36 > 0:10:40In actual fact, our galaxy is called the Milky Way and it's
0:10:40 > 0:10:44comprised of an estimated 200-400 billion stars!
0:10:44 > 0:10:46I've never actually counted them.
0:10:46 > 0:10:51That is the end of the first round. We are moving on, and we shall move
0:10:51 > 0:10:55into the second round with the scores at 2 - 0 to the Reds!
0:11:06 > 0:11:11That's all to come, but right now it is Mini Science.
0:11:11 > 0:11:15This is the round where our teams will be conducting their
0:11:15 > 0:11:16own experiments using
0:11:16 > 0:11:21ordinary household objects instead of elaborate scientific equipment.
0:11:21 > 0:11:25To help with this, please welcome Mini Miss!
0:11:27 > 0:11:32- Good day, Richard.- Miss?- Yes? - You know that time machine I built
0:11:32 > 0:11:37that brought you through time, but there were a few problems
0:11:37 > 0:11:40- and you came back as a ten year old? - Yes, Richard.- Where is it?
0:11:40 > 0:11:44I confiscated it.
0:11:44 > 0:11:48Until you learn to use it properly, you cannot have it back.
0:11:48 > 0:11:52Yes, Miss. Sorry, Miss. Anyway, what are we doing today?
0:11:52 > 0:11:56Well, today the teams are going to experiment with friction
0:11:56 > 0:11:59and inertia using eggs.
0:11:59 > 0:12:03Each team will have 12 beakers with water in them, 12 tubes, three
0:12:03 > 0:12:05placemats and some eggs.
0:12:05 > 0:12:10They have to make the eggs travel from the top of the tubes, into
0:12:10 > 0:12:15the water filled beakers without breaking them. And they
0:12:15 > 0:12:20- are only allowed to touch one object throughout the whole trick.- Miss, how
0:12:20 > 0:12:23- are they going to do that? - I'll show you.
0:12:23 > 0:12:25Wow! OK, so that's where I can
0:12:25 > 0:12:30see straight away that the friction and inertia comes into this. There's
0:12:30 > 0:12:35friction there and inertia here. Very clever, Miss. How many
0:12:35 > 0:12:38- eggs are they going to get to do this?- There are 12 eggs.
0:12:38 > 0:12:41The first member has to use three eggs.
0:12:41 > 0:12:46The second team member must use four, and the third team member must
0:12:46 > 0:12:51use five. And the winning team is the one to get the most amount of eggs in
0:12:51 > 0:12:54- their beakers without breaking them. - OK, fair enough.
0:12:54 > 0:12:57Get the most eggs in the beakers.
0:12:57 > 0:13:01If you were thinking that these eggs aren't real ones, I'm sorry,
0:13:01 > 0:13:06this is Blast Lab, of course they are. I shall demonstrate.
0:13:06 > 0:13:11Er, you! Could you demonstrate that this egg is real for me, please?
0:13:11 > 0:13:14No, here! I need to show it's a real egg. Look! That's a real egg.
0:13:14 > 0:13:20OK, teams, you've got to decide who's... Well, go on, then! Away!
0:13:20 > 0:13:24Right, teams, you have to decide who's going to do which number of
0:13:24 > 0:13:29eggs. So, I'm going to give you a bit of time to discuss that.
0:13:29 > 0:13:31Friction is the force that
0:13:31 > 0:13:36slows things down and rough surfaces have more friction than smooth ones.
0:13:36 > 0:13:40The cork on this side has more friction than the shiny side
0:13:40 > 0:13:44and it's friction that drags the towers when you pull the mat away.
0:13:44 > 0:13:48The reason the egg doesn't just go with them is inertia.
0:13:48 > 0:13:52If something is heavy, it takes more effort to get it moving.
0:13:52 > 0:13:56It's something Sir Isaac Newton dealt with in his First Law -
0:13:56 > 0:14:00If something is already moving, it doesn't want to stop,
0:14:00 > 0:14:04and if it's stopped, it doesn't really want to get moving.
0:14:04 > 0:14:06That's what he was getting at.
0:14:06 > 0:14:09So, the trick here is to move the mat quickly enough so
0:14:09 > 0:14:14that the egg's inertia will keep it where it is just for long enough for
0:14:14 > 0:14:18the mats to clear, then gravity takes over and the egg drops.
0:14:18 > 0:14:25That's the theory. OK, teams, have we decided who's doing three?
0:14:25 > 0:14:28Reds, you are in the lead on points now.
0:14:28 > 0:14:30It's 2 - 1 in the scores, so you get to decide.
0:14:30 > 0:14:34- Do you want to go first or second? - First.- Who's doing three?
0:14:34 > 0:14:36Who's going first? Jack.
0:14:36 > 0:14:38Well, step up. Get it all set up.
0:14:46 > 0:14:51In your own time, Jack, go! All three!
0:14:51 > 0:14:54APPLAUSE
0:14:59 > 0:15:03Yellows, the gauntlet has been thrown down there for you.
0:15:03 > 0:15:06So, who's going to do three first of all?
0:15:06 > 0:15:08- Martin.- Martin.
0:15:14 > 0:15:17In your own time, Martin, go for it!
0:15:18 > 0:15:19Yes! All three again.
0:15:19 > 0:15:21CHEERING
0:15:23 > 0:15:25You can't argue with that!
0:15:25 > 0:15:30It's a draw right now, Reds and Yellows, in this game. Reds, sorry,
0:15:30 > 0:15:33they did it perfectly as well. Now, the big four.
0:15:36 > 0:15:39Good luck, Jacob.
0:15:39 > 0:15:40All four! Look at that!
0:15:40 > 0:15:42CHEERING
0:15:42 > 0:15:46Jacob, were you a gunslinger in a previous existence or something?
0:15:46 > 0:15:49Because he just wandered up, yeah,
0:15:49 > 0:15:51did it and walked off!
0:15:51 > 0:15:54That was fantastic! Well, done! Yellows now.
0:15:57 > 0:16:02I can hardly watch. You've got to get all four to stay in.
0:16:02 > 0:16:04And you have!
0:16:04 > 0:16:05CHEERING
0:16:09 > 0:16:13This is the big one! No pressure here, but five...
0:16:16 > 0:16:19Five is a big ask. Audience, I...
0:16:19 > 0:16:25Yeah, I know! Audience here, I don't know if you've got spare clothes
0:16:25 > 0:16:30with you in the lab if the egg lands on you. It's possible.
0:16:31 > 0:16:33No way, that's all five done!
0:16:33 > 0:16:35CHEERING
0:16:38 > 0:16:39Ryan, you did the same!
0:16:39 > 0:16:43There's all of us getting tense, and the Reds just...
0:16:43 > 0:16:47Well, done! Well, that's all 12 safely landed for the Red Team.
0:16:47 > 0:16:51Yellows, obviously, you know what I'm going to say, which is
0:16:51 > 0:16:55they've done it all perfectly and, Tom, this is yours.
0:16:55 > 0:16:59Good luck, good luck, good luck, good luck!
0:16:59 > 0:17:01Oh, it's a disaster!
0:17:03 > 0:17:07Mind you, how did you manage to get that egg to stay on the edge?
0:17:07 > 0:17:11A round of applause! It was a good effort. The Red Team are
0:17:11 > 0:17:16the winners from that round. That's another point to the Reds.
0:17:16 > 0:17:17That is three to the Reds.
0:17:17 > 0:17:21You're under pressure there, Yellows. Seeing all of those eggs
0:17:21 > 0:17:23has made me a bit peckish.
0:17:23 > 0:17:27I wonder if friction, that we saw used there, could be used
0:17:27 > 0:17:29to cook me some breakfast.
0:17:29 > 0:17:34A Lab Rat sets about preparing a balanced meal of meat and egg.
0:17:34 > 0:17:37But he's not only a terrible cook,
0:17:37 > 0:17:41he's also forgotten the main ingredient of heat, fire!
0:17:41 > 0:17:45As his tiny excuse for a brain tries to formulate a plan,
0:17:45 > 0:17:49a lone wagon appears in the distance.
0:17:50 > 0:17:53That's just what we needed!
0:17:53 > 0:17:55An expert!
0:17:55 > 0:17:57Hello, I'm a fast-food expert.
0:17:57 > 0:18:02So, the plan is, if we can't harness the power of naked flame,
0:18:02 > 0:18:06we'll have to find another way to heat our brekkie.
0:18:06 > 0:18:09Using a copper-bottomed saucepan
0:18:09 > 0:18:12attached to the back of this fast-food wagon,
0:18:12 > 0:18:15we're going to find out if you can cook a meal by friction alone.
0:18:15 > 0:18:19As the frying pan is dragged along, there will be friction between it
0:18:19 > 0:18:24and the rough ground, so some of the frying pan's movement energy
0:18:24 > 0:18:27will be transferred into heat energy.
0:18:27 > 0:18:30This heat should then conduct through the pan to the food -
0:18:30 > 0:18:33but will this be enough to cook the breakfast?
0:18:33 > 0:18:37We're attaching a thermometer to tell us when we've reached
0:18:37 > 0:18:39optimal cooking temperature.
0:18:39 > 0:18:42Hopefully, this won't take too long, as a certain Lab
0:18:42 > 0:18:45Rat is more than a little peckish.
0:18:46 > 0:18:50Hold it right there, because I think there's
0:18:50 > 0:18:53another point in this. With the score at 3-0 to the Reds,
0:18:53 > 0:18:55we know you guys are going to get the head start
0:18:55 > 0:18:59for the Messy Mess Test. But think of it, Yellows, as a
0:18:59 > 0:19:03consolation point. And I'll give that point to the team
0:19:03 > 0:19:06that tells me correctly will it work, will it not?
0:19:06 > 0:19:10Will it create enough heat from the friction of dragging that saucepan
0:19:10 > 0:19:14behind the van to actually cook the Lab Rat's breakfast?
0:19:14 > 0:19:17Chat amongst yourselves and come to a conclusion.
0:19:17 > 0:19:21I'll give the point to the team that's closest. Audience, any ideas?
0:19:21 > 0:19:25- I think it won't work.- OK. - I do.- OK.- And I don't.
0:19:25 > 0:19:29All right... He does, and he quite clearly doesn't.
0:19:29 > 0:19:32So, we have opposing views in the audience.
0:19:32 > 0:19:34Teams, you've had time to think about it.
0:19:34 > 0:19:36- Have you come to a conclusion?- Yeah.
0:19:36 > 0:19:40- Reds? Yeah. OK, Yellows, what do you think?- No.- We say no.
0:19:40 > 0:19:44- You reckon no. OK.- Yes. - You reckon it will.
0:19:44 > 0:19:45If it does, you get the point,
0:19:45 > 0:19:48If not, Yellows get the point. Let's find out.
0:19:54 > 0:19:58Travelling at speeds of up to 50 miles an hour, our fast food van
0:19:58 > 0:20:04is a greasy blur of cholesterol as he tries his best to heat the pan.
0:20:04 > 0:20:07Time is running out and our Lab Rat is actually
0:20:07 > 0:20:11dribbling with anticipation. Well, I think that's what it was.
0:20:11 > 0:20:14It looks like breakfast is served!
0:20:14 > 0:20:16A quick temperature check.
0:20:16 > 0:20:1860 degrees.
0:20:18 > 0:20:22Well, it has definitely heated up, but is our food cooked?
0:20:22 > 0:20:26It doesn't look very appetising, I have to say.
0:20:26 > 0:20:28Well, eat up then, man!
0:20:29 > 0:20:32It appears that the food has failed to pass the taste test,
0:20:32 > 0:20:36and the health and safety test as well, I think.
0:20:36 > 0:20:41Oh, well, maybe a bowl of cereal wouldn't be such a bad idea.
0:20:41 > 0:20:44I don't think we can say that worked really,
0:20:44 > 0:20:47so the point goes to the Yellow Team. Well, done! It just didn't...
0:20:47 > 0:20:503-1 is the score right now. OK, teams, you've all got to go
0:20:50 > 0:20:53get ready for the Messy Messy Mess Test.
0:20:53 > 0:20:57If you go and get ready for that, and while you're doing that,
0:20:57 > 0:21:01I just want to check on something, because my Lab Rats claim to have
0:21:01 > 0:21:04found a way to harness brainpower and convert it into electricity.
0:21:04 > 0:21:08They say, if it works, they'll be able to power the whole lab.
0:21:08 > 0:21:11I've suggested they start with something smaller because
0:21:11 > 0:21:14I've spotted a flaw in this right from the very start.
0:21:14 > 0:21:18Dim the lab lights, please. We'll switch off lab power and we'll
0:21:18 > 0:21:21go over to Lab Rat power! Switch on your system, please.
0:21:21 > 0:21:24Concentrate on the game of chess and we'll see if it works.
0:21:24 > 0:21:29Yeah, as I suspected, not enough brainpower to light a single bulb!
0:21:29 > 0:21:30That's pathetic!
0:21:30 > 0:21:33Well, all right, pack it in. We'll deal with it later.
0:21:33 > 0:21:38Go and get your lunch. That's it! Keep thinking about food!
0:21:38 > 0:21:42We'll move on to the Messy Messy Mess Test...
0:21:44 > 0:21:47..which today is the Gungee Bungee,
0:21:47 > 0:21:51featuring my bungee-powered catapults. Right, here is the game!
0:21:51 > 0:21:54You have to get as many Prize Pods as you possibly can using
0:21:54 > 0:21:56the catapult across the tank full of
0:21:56 > 0:21:59unspeakably hideous gunge into the Prize Zone beyond.
0:21:59 > 0:22:03This being Blast Lab, there is, of course, a twist. You may have
0:22:03 > 0:22:06noticed, one member of each team is already standing in the tank.
0:22:06 > 0:22:08Comfortable in there? Good!
0:22:08 > 0:22:11I don't really care. You're in there, I'm not!
0:22:11 > 0:22:13Now, you have two jobs in there, OK?
0:22:13 > 0:22:18One job is to block the opposing team's Prize Pods as they come over
0:22:18 > 0:22:21the tank and try stop them getting into the Prize Zone.
0:22:21 > 0:22:24The other job is to retrieve your own teams Prize Pods when they
0:22:24 > 0:22:27land in there and get stranded, put them in the basket here, so
0:22:27 > 0:22:31that the loaders can get them back round to the firers and try again.
0:22:31 > 0:22:34Oh, one other very important rule -
0:22:34 > 0:22:40do not cross this tape, because somehow a shoal of biting
0:22:40 > 0:22:45piranhas made their home at this end of the tank and they really do bite.
0:22:45 > 0:22:47They do. A heck of an appetite.
0:22:47 > 0:22:50Somehow they made it through the metal grill,
0:22:50 > 0:22:52so just watch out for them.
0:22:52 > 0:22:55They can nip.
0:22:55 > 0:22:58Right, the team that gets the most Prize Pods into the Prize
0:22:58 > 0:23:02Zone at the other side of the tank, will win all of the prizes on those
0:23:02 > 0:23:06Prize Pods. The losing team has to blow their prizes up.
0:23:06 > 0:23:09It's all simple enough. Reds, you're ahead on points right now.
0:23:09 > 0:23:13You have a five second-advantage, so when you hear the first siren,
0:23:13 > 0:23:15you start firing.
0:23:15 > 0:23:18Yellows, wait until you hear the second siren, then start.
0:23:18 > 0:23:21Everybody clear on the rules? OK.
0:23:21 > 0:23:28Teams, you have some time to do this, and that some time starts now!
0:23:28 > 0:23:32Away go the Reds. Teamwork is the key to this one.
0:23:32 > 0:23:34Now, off go the Yellows.
0:23:35 > 0:23:40Reds meanwhile are already getting their eye in, and yes!
0:23:40 > 0:23:43The Reds already have one in the Prize Zone.
0:23:45 > 0:23:47Oh, and look at that! Martin was nearly taken out
0:23:47 > 0:23:51by one of his own Prize Pods! As we can see from the replay, that Prize
0:23:51 > 0:23:53Pod narrowly missed Martin's head!
0:23:55 > 0:23:59Meanwhile, the Reds are calmly going about their business. That business
0:23:59 > 0:24:03is scoring prizes in the Prize Zone, as another goes in for the Reds!
0:24:06 > 0:24:09The teams will have to keep this pace up
0:24:09 > 0:24:13as only my "some time" invention knows how much time is left,
0:24:13 > 0:24:16but it only knows that sometimes!
0:24:16 > 0:24:20The Reds are getting extraordinary height on their shots, making life
0:24:20 > 0:24:22very difficult for the Yellow blocker.
0:24:22 > 0:24:25It's raining Red Prize Pods in there!
0:24:25 > 0:24:28Yellows are going to have to pull something special out of
0:24:28 > 0:24:32the bag to win this one.
0:24:33 > 0:24:34And...yes!
0:24:34 > 0:24:37That's one in the Prize Zone for the Yellows.
0:24:37 > 0:24:41Is this the start of a comeback? No, not with shooting like that!
0:24:41 > 0:24:46The Reds are powering on. They might run out of Prize Pods at this rate.
0:24:48 > 0:24:51I cannot see a way back for the Yellows now.
0:24:51 > 0:24:56Five, four, three, two, one.
0:24:56 > 0:24:58Time is up!
0:24:59 > 0:25:01Time is up!
0:25:01 > 0:25:04Time is up! Well done, both teams.
0:25:04 > 0:25:05That is quite hard work, that.
0:25:05 > 0:25:08Right, let's find out which team has won.
0:25:08 > 0:25:11Lab Rats, if you would count them up for me, please.
0:25:11 > 0:25:13For the Yellow Team we have how many? We have three.
0:25:13 > 0:25:16For the Red Team, I think we have more.
0:25:16 > 0:25:19We have nine for the Red Team. Reds are the winners!
0:25:19 > 0:25:22Well, done, Reds. Let's have a look at what you've won.
0:25:22 > 0:25:26Ready, Nan? Shaun The Sheep Model Kit.
0:25:27 > 0:25:28A Super Cricket Set.
0:25:29 > 0:25:33A Bop It Game. A Marine Helicopter.
0:25:34 > 0:25:36Electronic Project Set.
0:25:37 > 0:25:41Hulk Smash Hands. A Giggle Wiggle.
0:25:41 > 0:25:43Horrible Science Book,
0:25:43 > 0:25:47and Hot Wheels Trick Track. Well done, Reds, you've
0:25:47 > 0:25:51just about cleared me out! Just about cleared me out.
0:25:51 > 0:25:55Yellows, this is a slightly less enjoyable bit because this is where
0:25:55 > 0:25:58we find out what you would have won, but haven't.
0:25:58 > 0:26:01So, it is the following.
0:26:01 > 0:26:05- A Horrible Science Book. - AUDIENCE: Ahhh!
0:26:05 > 0:26:08Shaun The Sheep Model Kit.
0:26:08 > 0:26:11That would have been yours, it would have been yours.
0:26:11 > 0:26:15Super Cricket Kit. Yeah. That, too, would have been yours, Yellows.
0:26:15 > 0:26:18But instead of being yours, you're going to blow it up because
0:26:18 > 0:26:20it's time for Bidet Goes Bang.
0:26:28 > 0:26:30Well, the time is upon us.
0:26:30 > 0:26:32The Reds are looking really
0:26:32 > 0:26:35quite happy, well done, behind your massive mountain of prizes.
0:26:35 > 0:26:40You've just about cleaned us out, well done. Well played, well won.
0:26:40 > 0:26:42Yellows, not feeling so good, I guess, right now.
0:26:42 > 0:26:45How are we feeling? About like that. Fair enough.
0:26:45 > 0:26:48What went wrong in that last game? Why did we struggle with it?
0:26:48 > 0:26:51Well, I was smaller than the Red person
0:26:51 > 0:26:53who was trying to hit them back.
0:26:53 > 0:26:57- Yes.- And the Reds weren't getting as many in the gunge, so it was
0:26:57 > 0:26:59easier to get them in the Prize Zone.
0:26:59 > 0:27:02Yes, it is a difficult game, that one.
0:27:02 > 0:27:04Right, so your prizes are all loaded in.
0:27:04 > 0:27:07- Who's going to press the plunger? - All of us.
0:27:07 > 0:27:10You're going to share the blame. That's the fairest way.
0:27:10 > 0:27:13OK, well, lift the plunger up into the firing position,
0:27:13 > 0:27:16Yellow Team, and be ready. Don't plunge it yet.
0:27:16 > 0:27:18We'll give you a countdown. Are we ready?
0:27:18 > 0:27:22Five, four, three, two, one.
0:27:24 > 0:27:26FLUSHING
0:27:27 > 0:27:30OK, we've learned a lot about friction today, so now you
0:27:30 > 0:27:34should be able to tell your friction fact from your friction fiction.
0:27:34 > 0:27:36I'll see you next time!
0:27:36 > 0:27:38CHEERING
0:27:43 > 0:27:46Blast Lab was recorded before a live studio audience.
0:27:46 > 0:27:49No Lab Rat was harmed during the filming.
0:27:49 > 0:27:51Well, not by me, anyway.
0:27:51 > 0:27:53Isn't that right, Nan?
