0:00:37 > 0:00:38Oh, oh.
0:00:41 > 0:00:46Hello. I'm Richard Hammond and welcome to my Blast lab!
0:00:46 > 0:00:49CHEERING
0:00:49 > 0:00:52I just had the weirdest dream.
0:00:52 > 0:00:55I was up last night working on my new gnome-cloning device.
0:00:55 > 0:00:58I'm not sure it's working properly. They've...
0:00:58 > 0:01:00invaded my mind - it's...terrifying.
0:01:00 > 0:01:03Anyway, this lab is a wonderful place, considered...
0:01:03 > 0:01:07Well, some say it's the scientific hub of the world.
0:01:07 > 0:01:10And they say it's the best lab in the world.
0:01:10 > 0:01:13And it's not just my mum and dad saying nice things about the place.
0:01:13 > 0:01:16Though it is MAINLY just my mum and dad.
0:01:16 > 0:01:19Today, two lucky teams of scientists have been invited
0:01:19 > 0:01:22to take part in experiments that might win them amazing prizes.
0:01:22 > 0:01:25Coming up, Fact Nav 2.0 with Oliver!
0:01:25 > 0:01:28CHEERING AND APPLAUSE
0:01:30 > 0:01:34In Mini Science, things get a bit sticky for my lab rats.
0:01:34 > 0:01:36CHEERING AND APPLAUSE
0:01:38 > 0:01:42My lab rats organise a battle of the elements, with a water cannon
0:01:42 > 0:01:44and a massive industrial wind machine.
0:01:44 > 0:01:47Let's just say mother nature will not be happening.
0:01:50 > 0:01:52In this week's Messy Messy Mess Test,
0:01:52 > 0:01:56is everyone's favourite gungee-related bungee catapult game.
0:01:56 > 0:01:59It's the Gungee Bungee!
0:02:02 > 0:02:06So, who would be the best person in the world to protect this lab?
0:02:06 > 0:02:09Well, it would probably be Vin Diesel,
0:02:09 > 0:02:13but the next best option would be this lady. It is Ninja Nan!
0:02:20 > 0:02:24Let's have a look at Nan, see what she's up to.
0:02:24 > 0:02:27She's surrounded by them!
0:02:27 > 0:02:30There's millions of them! They're stalking her.
0:02:30 > 0:02:32Nan, wake.... Best not to wake her.
0:02:32 > 0:02:37Right, let's have a look at who's trying to get in to my lab today.
0:02:40 > 0:02:41Hello.
0:02:41 > 0:02:45You look like you could be the Red Team, but we have to make sure.
0:02:45 > 0:02:47So, your names, please.
0:02:47 > 0:02:49- Callum!- Issy!- Lisa!
0:02:49 > 0:02:51Yep, that's what I've got.
0:02:51 > 0:02:55And who's going to do what, to prove you are who you say you are?
0:02:55 > 0:02:56Me.
0:02:56 > 0:03:00- I can turn my feet inside out and still walk.- Urgh!
0:03:00 > 0:03:02Good grief! OK.
0:03:02 > 0:03:05I believe you. Come on into the lab.
0:03:05 > 0:03:08APPLAUSE
0:03:08 > 0:03:12I just tried it. It is impossible. It's just you who can do that.
0:03:12 > 0:03:13You can come to here,
0:03:13 > 0:03:14but that's as far as you can go
0:03:14 > 0:03:17because Ninja Nan is watching you three.
0:03:17 > 0:03:21One final security check before we let you in to the lab, OK?
0:03:21 > 0:03:24And that is, we agreed a password with the Red Team.
0:03:24 > 0:03:26If you are them you know what it is.
0:03:26 > 0:03:28- What is the password? - ALL:- Toilet.
0:03:28 > 0:03:31That's what I've got. Why is it toilet?
0:03:31 > 0:03:35Because on my school residential trip I slept walked
0:03:35 > 0:03:38and I was found on the toilet at 2.00am.
0:03:38 > 0:03:41You sleepwalked into the lavatory? Well, could be convenient.
0:03:41 > 0:03:45Fair enough. I believe you then - you ARE the Red Team.
0:03:45 > 0:03:51You're cleared through security. Go and get ready for the first game!
0:03:52 > 0:03:54The Reds. We need a Yellow Team.
0:03:54 > 0:03:58Let's meet the bunch of people who say it's them.
0:03:58 > 0:04:00CHEERING AND APPLAUSE
0:04:03 > 0:04:04Argh! That's gnomes!
0:04:04 > 0:04:09There were gnomes just then! There are gnomes in the lab!
0:04:09 > 0:04:12CHEERING AND APPLAUSE
0:04:14 > 0:04:17OK. OK, well you do now look like the Yellow Team.
0:04:17 > 0:04:21So we need to check - your names, please. You are?
0:04:21 > 0:04:23- Holly!- Lucy!- John!
0:04:23 > 0:04:24Yep, fair enough.
0:04:24 > 0:04:28What hidden talent will prove you are the Yellow Team?
0:04:28 > 0:04:32- I can do a headstand. - John. OK - go on, then.
0:04:35 > 0:04:36Yeah.
0:04:36 > 0:04:41Yeah, you are standing on your head. I believe you. Come into the lab.
0:04:44 > 0:04:46All right,
0:04:46 > 0:04:50before we can be absolutely sure you are the real Yellow Team
0:04:50 > 0:04:56we agreed a password which you would know if you are they and not gnomes.
0:04:56 > 0:04:59- What do you think it is?- Pig.- Pig.
0:04:59 > 0:05:02Yes, that's what I've got. Why pig?
0:05:02 > 0:05:05I went to my uncle's farm and I opened a pig shed
0:05:05 > 0:05:08and a pig came rushing out and I fell on the floor.
0:05:08 > 0:05:11- You got run over by a pig? - Yeah.- Wow!
0:05:11 > 0:05:13- A special attack pig? - Yeah.
0:05:13 > 0:05:16We tried one of those here once. It didn't work out. All right,
0:05:16 > 0:05:21you ARE the Yellow Team. Go and get settled in ready for the first game.
0:05:21 > 0:05:23CHEERING
0:05:23 > 0:05:25OK, we have our two teams.
0:05:25 > 0:05:27For the next round I need a clever car.
0:05:27 > 0:05:29He knows all about the big bang, and not just the one
0:05:29 > 0:05:35that comes from his exhaust when you start him. Please welcome Oliver!
0:05:51 > 0:05:52CHEERING AND APPLAUSE
0:05:52 > 0:05:57There we are, docked into Fact Nav and hooked up.
0:05:57 > 0:05:59Up and running, here goes.
0:05:59 > 0:06:02Now, to keep Oliver absolutely up to the minute,
0:06:02 > 0:06:06I've fitted him with a very latest upgrade - Fact Nav 2.0.
0:06:06 > 0:06:10Unfortunately, the copy I bought was in the bargain bin
0:06:10 > 0:06:13at my local gadget shop because some of the parts were missing.
0:06:13 > 0:06:17And it turns out the missing parts were probably quite important,
0:06:17 > 0:06:20because as a result, not all of the facts
0:06:20 > 0:06:23he has in the system are entirely factual.
0:06:23 > 0:06:26They're incorrect. Teams, that's where you come in.
0:06:26 > 0:06:29I need you to tell me whether these science facts are true or false.
0:06:29 > 0:06:33If they turn out to be true, Oliver will let us know by doing this...
0:06:33 > 0:06:36HIGH-PITCHED SIREN
0:06:36 > 0:06:38And if they're false, he'll do this...
0:06:38 > 0:06:40LOW-PICTHED BEEPING
0:06:40 > 0:06:42Here's how to play.
0:06:42 > 0:06:46Three red lights for each team. Every time you answer correctly,
0:06:46 > 0:06:48we'll turn one of your lights green.
0:06:48 > 0:06:52The first team to get three green lights wins the game,
0:06:52 > 0:06:53takes a point and we move on.
0:06:53 > 0:06:56But, if you answer a question incorrectly,
0:06:56 > 0:07:01we will turn one of the other team's lights green.
0:07:01 > 0:07:03So think carefully about how you answer, because
0:07:03 > 0:07:08you could win the game for the other team. Everybody clear?
0:07:08 > 0:07:12Good. The first question is a nearest-to question.
0:07:12 > 0:07:13Here is your question.
0:07:13 > 0:07:21The number called "a google" is 1 followed by how many 0s?
0:07:21 > 0:07:28The number called "a google" is 1 followed by how many 0s?
0:07:28 > 0:07:31THEY WHISPER
0:07:31 > 0:07:35Got to hurry you for an answer now, teams.
0:07:36 > 0:07:39- 'Time's up.'- OK, I do need answers. Have both teams
0:07:39 > 0:07:41written down an answer? Reds?
0:07:41 > 0:07:43- Yellows?- Yeah.- OK.
0:07:43 > 0:07:47The number called "a google" is 1 followed by how many 0s?
0:07:47 > 0:07:50Reds, what do you think?
0:07:50 > 0:07:54- 13.- You think it's 1 then 13 zeros.- Yeah.- Yellows?
0:07:54 > 0:07:57- 1,000.- 1,000 zeros.
0:07:57 > 0:08:01OK, that's... Whoa, some difference in your answers there.
0:08:02 > 0:08:07The actual answer is, google is a one followed by...
0:08:07 > 0:08:12100 zeros, which means the Reds are closest with 13.
0:08:12 > 0:08:14The green light is lit.
0:08:18 > 0:08:22Let's ask the question of red. You get the first true or false.
0:08:22 > 0:08:25You've taken control of the game, that's good.
0:08:25 > 0:08:28You could of course lose control fairly quickly. Get this wrong,
0:08:28 > 0:08:32hand the green light to the Yellows. Then next question they get two.
0:08:32 > 0:08:36So, your science fact is,
0:08:36 > 0:08:41the longest ear hair in the world is ten centimetres long.
0:08:41 > 0:08:44Is that true or false? Have a chat, Reds. Have a good think.
0:08:47 > 0:08:49What do you think? Is it true or false?
0:08:49 > 0:08:52We think it's false cos we think it might be longer.
0:08:52 > 0:08:56- Really?- Yeah.- That's a confident answer from the Reds.
0:08:56 > 0:08:58OK, so, Oliver, the science fact is,
0:08:58 > 0:09:02the longest ear hair in the world is ten centimetres long.
0:09:02 > 0:09:05The Reds think it's false. Is it true or false?
0:09:05 > 0:09:07LOW-PITCHED BEEPING
0:09:07 > 0:09:10It is false. Another light is lit green for the Reds.
0:09:14 > 0:09:18You are right - it's actually over 18 centimetres long
0:09:18 > 0:09:21and it belongs to Anthony Victor of India.
0:09:21 > 0:09:23Right, Yellows,
0:09:23 > 0:09:25the Reds have two green lights.
0:09:25 > 0:09:27Here is your science fact.
0:09:27 > 0:09:33The box jellyfish has enough poison in it
0:09:33 > 0:09:36to kill 60 human beings.
0:09:36 > 0:09:37True or false?
0:09:37 > 0:09:41The box jellyfish has enough poison in it to kill 60 human beings.
0:09:41 > 0:09:44Is that true or false? Have a good think and a chat.
0:09:44 > 0:09:49Meanwhile, audience, what do you think? Vote with your feet.
0:09:49 > 0:09:53- OK, you all think that's true, yeah? - Yeah.- You think not.
0:09:53 > 0:09:55- No, I've seen a jellyfish.- Yeah.
0:09:55 > 0:09:56I've never been stung by one,
0:09:56 > 0:09:59but I don't think it could be that poisonous.
0:09:59 > 0:10:01OK, back to your places, audience.
0:10:01 > 0:10:04Let's find out the real answer.
0:10:04 > 0:10:06The box jellyfish has enough poison in it
0:10:06 > 0:10:08to kill 60 human beings. Is that true or false?
0:10:08 > 0:10:10- True.- You think it's true.
0:10:10 > 0:10:12Oliver, the Yellows think it's true.
0:10:12 > 0:10:16Is it true or false?
0:10:16 > 0:10:20- HIGH-PITCHED SIREN - It is true. You're still in the game,
0:10:20 > 0:10:24well done. It is true. So that's a green light lit.
0:10:24 > 0:10:28It does live in Australia. In the sea,
0:10:28 > 0:10:32obviously, around Australia. It's also known as the sea wasp.
0:10:32 > 0:10:36OK, Reds, so the Yellows have stayed in the game
0:10:36 > 0:10:40by the skin of their teeth. Well done, team.
0:10:40 > 0:10:42This is a critical one for you. Get this right, you win.
0:10:42 > 0:10:46Get it wrong, the Yellows will then have two green lights
0:10:46 > 0:10:49and can win on their next question.
0:10:49 > 0:10:53Out of all the planets in the solar system,
0:10:53 > 0:10:55Jupiter has the fewest moons.
0:10:55 > 0:10:58True or false? Right, what do you think?
0:11:01 > 0:11:03- False.- You think it's false.
0:11:03 > 0:11:06False. Cos we think every planet has a moon
0:11:06 > 0:11:08and Earth only has one, so that must be it.
0:11:08 > 0:11:11Logically thinking going on there.
0:11:11 > 0:11:14Out of all the planets in the solar system,
0:11:14 > 0:11:16Jupiter has the fewest moons.
0:11:16 > 0:11:18Oliver, is that true or false?
0:11:18 > 0:11:21- LOW-PITCHED BEEPING - It is false. It is false.
0:11:21 > 0:11:24That means a third light is lit green for the Reds.
0:11:24 > 0:11:26CHEERING AND APPLAUSE
0:11:29 > 0:11:31Jupiter has the most moons. 62.
0:11:31 > 0:11:34Although only 49 have official names.
0:11:34 > 0:11:36I'm not surprised - you won't remember them all!
0:11:36 > 0:11:39With three lights lit green, that means the Reds win.
0:11:39 > 0:11:41The score then is 1-0.
0:11:57 > 0:12:00Sometimes it does get very lonely here in the Lab.
0:12:00 > 0:12:03When you lot have all gone home and I'm the only human here.
0:12:03 > 0:12:06Lab rats don't count, obviously, or gnomes.
0:12:06 > 0:12:09So I invented a time machine to bring my old science teacher
0:12:09 > 0:12:12back from school through time to help out in the Lab
0:12:12 > 0:12:13and keep me company.
0:12:13 > 0:12:16And it worked. The machine worked.
0:12:16 > 0:12:19She arrived. And she's not much company because all she ever does
0:12:19 > 0:12:21is keep reminding me that I had
0:12:21 > 0:12:23the time machine's anti-ageing dial turned up
0:12:23 > 0:12:26way too high, which is why she stepped out of it
0:12:26 > 0:12:30as a ten-year-old girl. It is, of course, Mini Miss.
0:12:30 > 0:12:31CHEERING AND APPLAUSE
0:12:35 > 0:12:40- Hello.- What are you drivelling on about, Richard?
0:12:40 > 0:12:44May I remind you of the time you had the anti-ageing dial
0:12:44 > 0:12:46turned up way too high, and...
0:12:46 > 0:12:49Yes, Miss, I've got it. I'm sorry, it won't happen again.
0:12:49 > 0:12:52- It'd better not.- It won't. What have you got for us today?
0:12:52 > 0:12:55Well, today, the teams are playing a game I like to call...
0:12:57 > 0:13:00Anything that involves suspending lab rats from the ceiling
0:13:00 > 0:13:04- is good with me.- Pipe down and listen up, Richard.- Sorry, Miss.
0:13:04 > 0:13:08The teams have to use their colander catapult launchers to fire
0:13:08 > 0:13:11these Velcro-covered balls at their very own lab rat.
0:13:11 > 0:13:13If the ball hits, it will stick.
0:13:13 > 0:13:17- I bet the team with most balls stuck to their lab rat wins.- Correct.
0:13:17 > 0:13:20Yeah, I'm getting really good at these now.
0:13:20 > 0:13:22Teams, you have some time
0:13:22 > 0:13:25to get as many balls stuck to your lab rat as you can.
0:13:25 > 0:13:29Think carefully about trajectory, the path it's taking, and power -
0:13:29 > 0:13:32how much energy you're giving it to get there.
0:13:32 > 0:13:35OK, at some time, if you're ready, you ready?
0:13:35 > 0:13:38That some time starts now.
0:13:38 > 0:13:39Away we go.
0:13:39 > 0:13:42Both teams off to a good start,
0:13:42 > 0:13:46already sticking balls to those idiot lab rats.
0:13:46 > 0:13:50That's good because no-one knows how long some time is.
0:13:50 > 0:13:56The Yellows look to be ahead and, yes, there's another point for them.
0:13:56 > 0:13:59The Reds need to catch up, but not with firing like that.
0:13:59 > 0:14:02Oh, and yet another one for the Yellows. And another one.
0:14:02 > 0:14:06Head shot, absolutely classic move.
0:14:06 > 0:14:08To talk science, Mini Miss has joined them.
0:14:08 > 0:14:11- Miss?- Yes, Richard. - Do we NEED these microphones?
0:14:11 > 0:14:14- No, Richard. - But they look good, don't they?
0:14:14 > 0:14:17- Yes, Richard.- We look like sports commentators.- Shut up, Richard.
0:14:17 > 0:14:20This game is all about energy transfer, isn't it?
0:14:20 > 0:14:23- That's right.- Energy can never be made or destroyed,
0:14:23 > 0:14:26it just changes from one form to another.
0:14:26 > 0:14:30So, as the teams pull back their colanders, energy is transferred
0:14:30 > 0:14:32from their arms into the bungees,
0:14:32 > 0:14:36- where it's stored a potential... - Potential energy.
0:14:36 > 0:14:39As soon as the colander is let go this...
0:14:39 > 0:14:43- Potential energy.- ..potential energy is transferred into movement, or...
0:14:43 > 0:14:45- Kinetic.- ..kinetic energy.
0:14:45 > 0:14:47That shoots the colander and ball forwards.
0:14:47 > 0:14:48The colanders and bungees
0:14:48 > 0:14:51are attached to the posts, so they get pulled back again.
0:14:51 > 0:14:53They stop, but the balls aren't,
0:14:53 > 0:14:56so they fly forwards, hopefully towards the lab rats.
0:14:56 > 0:14:58- Correct, Richard.- Thank you, Miss.
0:14:58 > 0:15:00While I've been chatting to Mini Miss,
0:15:00 > 0:15:03the Reds have really come back into this.
0:15:03 > 0:15:05It's too close to call.
0:15:08 > 0:15:10Three, two, one more, one more!
0:15:10 > 0:15:11CHEERING AND APPLAUSE
0:15:14 > 0:15:19That last one was a close one for you Reds, that really was.
0:15:19 > 0:15:22So, lab rats, for the Yellows, how many do we have?
0:15:22 > 0:15:2610, 14. 14 for the Yellows. For the Reds, what have we got?
0:15:26 > 0:15:31Ten, 13, that means a win for the Yellows there. Well done.
0:15:31 > 0:15:33CHEERING AND APPLAUSE
0:15:33 > 0:15:37That was a close run thing team, very close.
0:15:37 > 0:15:40Looking at those wimpy lab rats makes me think that
0:15:40 > 0:15:43they could do with a bit of toughening up. Be good for them.
0:15:46 > 0:15:49Fed up with having no-one she can trust to help with security
0:15:49 > 0:15:55at the lab, Ninja Nan has sent one of our lab rats to toughen up.
0:15:55 > 0:15:58This particular lab rat, Rattius Play, says he's the toughest,
0:15:58 > 0:16:03meanest, baddest lab rat of all time, ever.
0:16:05 > 0:16:09Well, let's put that to the test and crowbar in an excuse for
0:16:09 > 0:16:11an experiment at the same time.
0:16:11 > 0:16:15And his opponent today, the inanimate object better known
0:16:15 > 0:16:18as a freestanding punchbag, the base of which is
0:16:18 > 0:16:21heavily weighted down with 100kg of sand.
0:16:21 > 0:16:24The challenge we're setting Rattius,
0:16:24 > 0:16:28can he knock the punchbag down using only his fists?
0:16:28 > 0:16:31This is all about the punchbag's central gravity
0:16:31 > 0:16:32and the width of its base.
0:16:32 > 0:16:34For our punchbag to keep upright,
0:16:34 > 0:16:37its centre of gravity must stay directly above its base.
0:16:37 > 0:16:40If the top of the punchbag can be pushed sideways enough
0:16:40 > 0:16:43for its centre of gravity to reach past its base,
0:16:43 > 0:16:48then gravity can take control and topple the punchbag.
0:16:48 > 0:16:50Round one begins.
0:16:50 > 0:16:57He's showing no mercy, unleashing a flurry of devastating blows.
0:16:57 > 0:17:00Doesn't seem to be having much of an effect, though,
0:17:00 > 0:17:04with the punchbag laughing at his pathetic pugilistic skills.
0:17:04 > 0:17:09He's run out of time and the punchbag is still standing.
0:17:09 > 0:17:11Oh, hold on, I spoke too soon.
0:17:11 > 0:17:13He's thought of another way to knock it down.
0:17:13 > 0:17:15Wind power, more his style.
0:17:15 > 0:17:20This huge electric fan is capable of blasting a constant stream of air
0:17:20 > 0:17:23at speeds of up to 110 miles an hour.
0:17:23 > 0:17:27But will that be enough to finally topple the steeping behemoth
0:17:27 > 0:17:30that is the freestanding punchbag?
0:17:33 > 0:17:36Well, some wobbling there,
0:17:36 > 0:17:38but it's not looking good.
0:17:38 > 0:17:41Time's up and another victory for the punchbag.
0:17:41 > 0:17:46Can no-one challenge this silent giant of the boxing world?
0:17:46 > 0:17:50Well, what are the chances? A fireman! That could work.
0:17:50 > 0:17:54So can our fireman succeed where the other two methods have failed?
0:17:54 > 0:17:57He has a hose connected to a fire hydrant that can
0:17:57 > 0:18:01shoot out up to 475 litres a minute.
0:18:01 > 0:18:06But will this be enough to knock down the punchbag?
0:18:06 > 0:18:08So, hold the experiment right there.
0:18:08 > 0:18:10There's another point up for grabs for the teams.
0:18:10 > 0:18:14It's transfer of energy. Energy being put into the bag
0:18:14 > 0:18:15and failing to knock it over.
0:18:15 > 0:18:19Punch power wasn't enough. We saw wind power wasn't enough.
0:18:19 > 0:18:22Will water power do it?
0:18:22 > 0:18:23Will that be enough?
0:18:23 > 0:18:27Have a think because there's another point up for grabs right now.
0:18:27 > 0:18:29Meanwhile, while you're thinking,
0:18:29 > 0:18:31I'm going to go over to the audience.
0:18:31 > 0:18:35Have a proper chat about everything you can.
0:18:35 > 0:18:38Yeah, there you go. Thank you.
0:18:38 > 0:18:40So, audience, what do you reckon?
0:18:40 > 0:18:44- Well, I think the water power might work.- You think it might?- Yeah.
0:18:44 > 0:18:46It takes quite a lot of energy to knock the bag over,
0:18:46 > 0:18:50doesn't it? It looks pretty heavy. Yeah, I think it...
0:18:50 > 0:18:55maybe knock it down, but it depends how fast it pushes out.
0:18:55 > 0:19:00How do you think the bag's staying up? What's holding it up?
0:19:00 > 0:19:04The sand must be so heavy that it won't be pushed down.
0:19:04 > 0:19:06Because it's weighted at the bottom,
0:19:06 > 0:19:10all of the centre of gravity, the heavy bit of it is at the bottom.
0:19:10 > 0:19:13Good, good, good. Right then, teams.
0:19:16 > 0:19:21- Yellows, will water power do it? - We think it will.- You think it will.
0:19:21 > 0:19:23- Reds.- Yes, I think it will. Yes, it will.
0:19:23 > 0:19:26You're going for yes. Both teams are going for yes.
0:19:26 > 0:19:29Only one way to find out - on with the experiment.
0:19:29 > 0:19:34After watching this man embarrass himself on more than one occasion,
0:19:34 > 0:19:36this man thinks he can finally
0:19:36 > 0:19:40topple the freestanding punchbag using water power.
0:19:40 > 0:19:42Let's find out if he's right.
0:19:42 > 0:19:46Three, two, one, fire.
0:19:49 > 0:19:53And with the greatest of ease and a whole lot of water,
0:19:53 > 0:19:57the punchbag is finally knocked to the ground. It's a knockout.
0:19:57 > 0:19:59CHEERING AND APPLAUSE
0:19:59 > 0:20:02water power was enough. Both teams are right.
0:20:02 > 0:20:05It's an extra point to both teams. Means, now, 2-2.
0:20:05 > 0:20:08CHEERING AND APPLAUSE
0:20:09 > 0:20:14OK, teams, get changed into chemical protective suits, away you go.
0:20:17 > 0:20:19I don't think that lab rat boxer
0:20:19 > 0:20:23took his defeat at the hands of mother nature very well.
0:20:23 > 0:20:28With the punchbag well and truly beaten, our brave loser, Rattius,
0:20:28 > 0:20:30comes in to offer his condolences.
0:20:30 > 0:20:32That's not very sporting.
0:20:32 > 0:20:34Nor is that, but it's very funny.
0:20:34 > 0:20:37Rattius once more flailing his arms, but to no effect.
0:20:43 > 0:20:46So, if you want to knock out a lab rat and you've got a choice
0:20:46 > 0:20:49between a water cannon and a wind machine, use a water cannon.
0:20:49 > 0:20:53Unless you have neither, then use the old fashion boxing glove.
0:20:53 > 0:20:54Let me demonstrate.
0:20:54 > 0:20:56There's another one, look.
0:20:56 > 0:21:00Oh, what a simple but effective tool!
0:21:00 > 0:21:02Never fails. Don't worry, they're lab rats,
0:21:02 > 0:21:04they're designed for that sort of thing.
0:21:04 > 0:21:10Let's move on to something far more important. It is time for...
0:21:10 > 0:21:14Oh, yeah, this is my bungee-powered catapult.
0:21:14 > 0:21:16I invented it to investigate the Blast Lab cat
0:21:16 > 0:21:19could beat a cheetah in a 100 metre race. It did.
0:21:19 > 0:21:23It might have taken an unfortunate route - cut through a wall or two -
0:21:23 > 0:21:26but it still beat the cheetah, that was the important thing.
0:21:26 > 0:21:28Anyway this week's moggy, moggy mess...
0:21:28 > 0:21:31I mean Messy, Messy, Mess Test is the gungee bungee.
0:21:31 > 0:21:34Teams, you've got to use these catapults to fire prize pods
0:21:34 > 0:21:38over this tank and into the prize zone on the other side.
0:21:38 > 0:21:40It's as simple as that.
0:21:40 > 0:21:42The prizes represented by what's written
0:21:42 > 0:21:45on the prize pods include a volcano game,
0:21:45 > 0:21:49a fashion styling set and a marine copter. But there's a catch.
0:21:49 > 0:21:52Technically it's a catchER -
0:21:52 > 0:21:54each team has a member standing in the tank.
0:21:54 > 0:21:57Your job is to intercept the other team's prize pods
0:21:57 > 0:22:01as they arc gracefully across the tank towards the prize zone. OK?
0:22:01 > 0:22:05Each team has the option at any time
0:22:05 > 0:22:09to fire these to their team-mates. These are...
0:22:09 > 0:22:11Giant hands of glory.
0:22:11 > 0:22:14That WAS a gnome. These can be used to stop the opposing team's
0:22:14 > 0:22:18prize pods more effectively than if they just used their own bare hands.
0:22:18 > 0:22:21When you're firing one of these across, you could be firing
0:22:21 > 0:22:23a prize pod instead.
0:22:23 > 0:22:27It's down to you to work out your tactics. Deploy them carefully.
0:22:27 > 0:22:31Only the prize pods in the prize zone at the end of the game count.
0:22:31 > 0:22:33The team with the most prize pods wins.
0:22:33 > 0:22:36You have some time to get as many prize pods across the tank
0:22:36 > 0:22:41and into the prize zone, as you can. Your some time starts...now.
0:22:41 > 0:22:45As it's a draw, both teams are kicking off at the same time.
0:22:45 > 0:22:48And the teams are wasting no some time.
0:22:48 > 0:22:51Yellows are off the mark.
0:22:53 > 0:22:58Another. John, the Yellows' firer, is like a machine out there.
0:22:58 > 0:23:00Atchoo!
0:23:00 > 0:23:02Speaking of machines, that's Alan,
0:23:02 > 0:23:04my massive robot, who has the most colossal cold.
0:23:04 > 0:23:06Sorry, everyone.
0:23:06 > 0:23:09The blockers did well to get out of the way of that one.
0:23:12 > 0:23:14Oh, but a great block from Issy.
0:23:14 > 0:23:19The Reds need more of that if they want to get back in this game.
0:23:19 > 0:23:22And finally the Reds get their first prize pod into the prize zone.
0:23:22 > 0:23:27And another. Is this the start of a great comeback? It could be.
0:23:27 > 0:23:32Callum has his eye in there. Look out, the Yellows.
0:23:32 > 0:23:34Well, it really is anybody's game now.
0:23:34 > 0:23:36There is nothing separating them.
0:23:41 > 0:23:45The blockers are working overtime.
0:23:45 > 0:23:48But the Reds grab another.
0:23:54 > 0:23:57And again, back come the Yellows.
0:23:57 > 0:24:01I've never seen a Messy, Messy Mess Test like it.
0:24:01 > 0:24:03The teams have to be quick.
0:24:07 > 0:24:12OK. Hold. That is the end of the game.
0:24:12 > 0:24:14Time for the big tot up.
0:24:14 > 0:24:17Let's check with the lab rats.
0:24:17 > 0:24:21For the Yellows, indicate with your little paw. Hold it in the air.
0:24:21 > 0:24:24Five. For the Reds, what have we got?
0:24:24 > 0:24:27Four for the Reds, that means it is a Yellow victory!
0:24:27 > 0:24:32The Yellows win. Well done, Yellows.
0:24:32 > 0:24:35Right, let's see what you've won here. Are you ready, Ninja Nan?
0:24:35 > 0:24:38A radio controlled spider.
0:24:38 > 0:24:41Tomb of Doom.
0:24:41 > 0:24:44A butterfly garden.
0:24:44 > 0:24:47Transforming ball.
0:24:47 > 0:24:48And a flying UFO.
0:24:48 > 0:24:50CHEERING AND APPLAUSE
0:24:50 > 0:24:55That is the haul of prizes the Yellow Team will be taking home.
0:24:55 > 0:24:58Reds, out of interest, we should probably find out
0:24:58 > 0:25:00what you would have won, had you won.
0:25:00 > 0:25:02Each of you would have been taking home...
0:25:02 > 0:25:06- Transforming ball, for each of you, rather nice.- AUDIENCE: Ah.
0:25:06 > 0:25:10- A butterfly garden for each of you. - Ah.
0:25:10 > 0:25:14- A board game for each of you.- Ah.
0:25:14 > 0:25:19- A volcano game.- Ah.- Yeah, yeah.
0:25:19 > 0:25:21But here at Blast Lab there are only three rules.
0:25:21 > 0:25:24Last person out of the Lab has to turn out the lights,
0:25:24 > 0:25:27never, ever open the windows as the killer moles get in,
0:25:27 > 0:25:30and the losing team has to blow up their prizes.
0:25:30 > 0:25:33That third rule is the most important one right now
0:25:33 > 0:25:36because it's time for Bidet Goes Bang!
0:25:43 > 0:25:48Yellows, well played, well played. All of these coming home with you.
0:25:48 > 0:25:51That feels good. Reds, you did so well.
0:25:51 > 0:25:55You held it at a draw through most of the game and in the end
0:25:55 > 0:25:58you didn't do the winning thing, you did the losing thing instead.
0:25:58 > 0:26:04Instead of taking home a huge wheelbarrow full of prizes.
0:26:04 > 0:26:07You're going to follow me now on a long and treacherous walk of shame.
0:26:07 > 0:26:14Follow me. Here you are. Console them for they are sad.
0:26:14 > 0:26:17They are sad, console them.
0:26:25 > 0:26:27Callum, Issy, Lisa,
0:26:27 > 0:26:30- in the end, the gungee bungee just didn't go your way, did it?- No.
0:26:30 > 0:26:36Bad luck. Still at least you get to blow everything up in the end, yeah.
0:26:36 > 0:26:38You know what to do, lift the plunger, please.
0:26:38 > 0:26:41Audience, we'll count them down from,
0:26:41 > 0:26:46five, four, three, two, one.
0:26:55 > 0:26:58Today, we have used giant wind machines and fire engines
0:26:58 > 0:27:01to investigate balance and catapults
0:27:01 > 0:27:05and to learn that, unlike lab rats, energy can't be destroyed.
0:27:05 > 0:27:06See you next time.
