Right, would you like my autograph as well? | 0:00:35 | 0:00:37 | |
It's my lab! He's just a lab rat. | 0:00:37 | 0:00:40 | |
He can't even write, look. This is...pathetic. | 0:00:40 | 0:00:43 | |
Oh, thank you. Hello and welcome to MY Blast Lab. | 0:00:43 | 0:00:47 | |
Yeah. | 0:00:47 | 0:00:49 | |
CHEERING AND APPLAUSE | 0:00:49 | 0:00:51 | |
OK. Yeah, this is the BEST laboratory in the whole... | 0:00:51 | 0:00:56 | |
OK, maybe not the best. The biggest laboratory in the whole... | 0:00:56 | 0:00:59 | |
maybe not the biggest laboratory in the world. | 0:00:59 | 0:01:02 | |
The best laboratory currently on television right now, | 0:01:02 | 0:01:06 | |
with him in it and a big tank of toxic goo. | 0:01:06 | 0:01:09 | |
Yeah, it is. Coming up in a moment, we'll have two teams of scientists, | 0:01:09 | 0:01:14 | |
competing in top-level scientific challenges to win excellent prizes. | 0:01:14 | 0:01:18 | |
With a mountain of knowledge and unfixable fountain of engine oil, | 0:01:18 | 0:01:22 | |
it's Oliver and his soon-to-be world famous Fact Nav 2.0. | 0:01:22 | 0:01:26 | |
In Mini Science, we witness a world first, and possibly... | 0:01:30 | 0:01:35 | |
last, as our teams conquer friction by combining one of the slippiest | 0:01:35 | 0:01:38 | |
man-made substances on the planet with giant frying pans. | 0:01:38 | 0:01:42 | |
Meanwhile, my lab rats get their paws on a slow-motion camera | 0:01:46 | 0:01:49 | |
and uncover the amazing world behind boring everyday things. | 0:01:49 | 0:01:52 | |
And in this week's Messy Messy Mess Test, we play bridge. | 0:01:56 | 0:01:59 | |
No, not Ninja Nan's favourite card game, but the one and, | 0:01:59 | 0:02:03 | |
for planning permission reasons, the only Bridge of Destiny. | 0:02:03 | 0:02:06 | |
'The Bridge of Destiny!' | 0:02:06 | 0:02:10 | |
Yeah. Now, what would you say if I told you this high-security lab | 0:02:10 | 0:02:14 | |
was only protected by an elderly lady? | 0:02:14 | 0:02:16 | |
You'd probably say, "I know, Richard. | 0:02:16 | 0:02:18 | |
"I've watched Blast Lab loads. She's a Ninja." | 0:02:18 | 0:02:21 | |
And you'd be right. Here she is. | 0:02:21 | 0:02:22 | |
Let's see what Ninja Nan and her friends from Cobra Squad are up to. | 0:02:30 | 0:02:33 | |
Oh, no. Looks like things have got nasty. | 0:02:33 | 0:02:37 | |
Somebody's only gone and done Ninja Nan's word search without asking. | 0:02:37 | 0:02:40 | |
I feel bad now. It was me that did it. Let's not say anything. | 0:02:40 | 0:02:44 | |
Let's instead have a look at who's trying to get into my lab today. | 0:02:44 | 0:02:49 | |
CHEERING AND APPLAUSE | 0:02:49 | 0:02:52 | |
Hello. So, you three say you're the Red Team. All right. | 0:02:54 | 0:02:57 | |
We have to be sure. For security reasons, identify yourselves. | 0:02:57 | 0:03:01 | |
-Ashley. -Michael. -Ronan. | 0:03:01 | 0:03:03 | |
Ashley, Michael, Ronan. Yes, that checks out. | 0:03:03 | 0:03:06 | |
Under talent, who's doing what for us? | 0:03:06 | 0:03:08 | |
I can do kick-boxing. | 0:03:08 | 0:03:10 | |
Oh, yes, yes, that's kick-boxing going on. | 0:03:10 | 0:03:13 | |
Come on into the lab, please. | 0:03:13 | 0:03:14 | |
APPLAUSE | 0:03:14 | 0:03:18 | |
So you three claim to be the Red Team. | 0:03:19 | 0:03:21 | |
Just before I can give you security clearance | 0:03:21 | 0:03:24 | |
and full access to the lab, we have agreed a password. | 0:03:24 | 0:03:27 | |
-What do you think it is? -Flying. | 0:03:27 | 0:03:29 | |
Flying is what I've got written down here. Why that? | 0:03:29 | 0:03:32 | |
-It was our first time flying yesterday. -To get to the lab? | 0:03:32 | 0:03:35 | |
I believe you. You're accepted and pass through security. | 0:03:35 | 0:03:38 | |
Go and get settled, ready for the first game. That is your Red Team. | 0:03:38 | 0:03:42 | |
There they are. | 0:03:42 | 0:03:44 | |
Great. We've got a Red Team. That's good. | 0:03:44 | 0:03:47 | |
What we need now is a Yellow Team, and these three say it's them. | 0:03:47 | 0:03:51 | |
CHEERING AND APPLAUSE | 0:03:51 | 0:03:55 | |
Hello, hello. So, you three claim to be the Yellow Team. | 0:03:56 | 0:04:00 | |
You could be anybody. Just for security reasons, | 0:04:00 | 0:04:02 | |
-identify yourselves by name. -Zoe. -Jacob. -Aidan. | 0:04:02 | 0:04:06 | |
Zoe, Jacob, Aidan, that's what I've got on the file here. | 0:04:06 | 0:04:09 | |
What can you do to prove you are who you say? | 0:04:09 | 0:04:11 | |
I can bend around a broom. | 0:04:11 | 0:04:13 | |
I don't even understand. You'll have to demonstrate this. | 0:04:13 | 0:04:17 | |
OK. | 0:04:17 | 0:04:18 | |
Oh...oh! | 0:04:18 | 0:04:20 | |
Ow! OK, fair enough. Eh... Well, | 0:04:20 | 0:04:23 | |
I'm assuming nobody else here could do that so, yes, you can come in. | 0:04:23 | 0:04:28 | |
APPLAUSE | 0:04:28 | 0:04:32 | |
Right, we've agreed a password with the real Yellow Team. | 0:04:32 | 0:04:35 | |
If you are, then you would know what it is. | 0:04:35 | 0:04:38 | |
-Water. -I've got it written down. | 0:04:38 | 0:04:39 | |
Why water? Because it's really important? | 0:04:39 | 0:04:42 | |
Because when my mum was sunbathing, | 0:04:42 | 0:04:45 | |
I threw a bottle of water out of the window on to her. | 0:04:45 | 0:04:48 | |
Whoa, that was ill-advised! | 0:04:48 | 0:04:50 | |
-I should explain, you're all brothers and sisters. -Yes. | 0:04:50 | 0:04:53 | |
Happy family. Well, happy family | 0:04:53 | 0:04:55 | |
-until that moment, I'm guessing. -Kind of. | 0:04:55 | 0:04:58 | |
Well, fair enough. Water it is then. | 0:04:58 | 0:05:00 | |
Go and get settled in. That is the Yellow Team. We have a Yellow Team. | 0:05:00 | 0:05:04 | |
CHEERING | 0:05:04 | 0:05:07 | |
Next, it's time to meet my favourite automobile in this lab. | 0:05:07 | 0:05:11 | |
What it lacks in horsepower, he makes up for in headlight power. | 0:05:11 | 0:05:14 | |
No, he doesn't. They're terrible. He makes up for | 0:05:14 | 0:05:17 | |
in a horrible knocking sound in fourth. It is Oliver. | 0:05:17 | 0:05:20 | |
CHEERING | 0:05:38 | 0:05:40 | |
Let's get you docked into Fact Nav and get you connected up and ready. | 0:05:40 | 0:05:44 | |
OK. Systems up and running. Good. | 0:05:44 | 0:05:49 | |
Now, Oliver here has got Fact Nav 2.0. | 0:05:49 | 0:05:52 | |
It's a system that can provide you with millions of scientific facts, | 0:05:52 | 0:05:55 | |
when installed by a qualified professional. | 0:05:55 | 0:05:59 | |
However, when it's installed by an unqualified amateur, like, me, | 0:05:59 | 0:06:04 | |
for instance, about half the facts turn out to be wrong. | 0:06:04 | 0:06:07 | |
This is where you come in. You have to tell me whether the science facts | 0:06:07 | 0:06:11 | |
I give you are true or false. | 0:06:11 | 0:06:13 | |
If they turn out to be true, Oliver will then let us know by doing this. | 0:06:13 | 0:06:16 | |
CAR HORN BEEPS REPETITIVELY | 0:06:16 | 0:06:19 | |
If they turn out to be false, he'll do this. | 0:06:19 | 0:06:22 | |
FOG HORN WAILS | 0:06:22 | 0:06:24 | |
That means false. Here's how we play the game. | 0:06:24 | 0:06:26 | |
Each team has three red lights. Every time you answer | 0:06:26 | 0:06:29 | |
a question correctly, I'll turn one of your lights green. | 0:06:29 | 0:06:33 | |
The first team to get three green lights | 0:06:33 | 0:06:35 | |
wins the game, they take a point and we move on. | 0:06:35 | 0:06:38 | |
One important thing, though. | 0:06:38 | 0:06:40 | |
If you get a question wrong, I'll light a light green | 0:06:40 | 0:06:43 | |
for the other team. Understand the rules? | 0:06:43 | 0:06:46 | |
-Yes. -Right. Teams, the first question is a nearest-to question. | 0:06:46 | 0:06:50 | |
What is the highest recorded temperature on Mercury? | 0:06:50 | 0:06:55 | |
What is the highest recorded temperature on Mercury? | 0:06:55 | 0:06:58 | |
-'Time's up.' -Yellows, what have you got? 253 degrees Celsius. Reds? | 0:07:03 | 0:07:08 | |
3,400 degrees Celsius. | 0:07:08 | 0:07:10 | |
The real answer is... | 0:07:10 | 0:07:13 | |
467 degrees Celsius, which means the Yellows are closest. | 0:07:13 | 0:07:17 | |
It's a green light for the Yellows. | 0:07:17 | 0:07:19 | |
Sorry, Reds. Don't worry. This game can turn so quickly. | 0:07:19 | 0:07:25 | |
That means, Yellows, you've taken control of the game. | 0:07:25 | 0:07:28 | |
You have a green light lit. You get the first true or false question. | 0:07:28 | 0:07:32 | |
And here it comes. | 0:07:32 | 0:07:33 | |
The owl noises, "too wit too woo" is actually made by two owls, | 0:07:33 | 0:07:40 | |
not just one. Have a little chat and think about it. | 0:07:40 | 0:07:43 | |
While you're doing that, Yellows, | 0:07:43 | 0:07:45 | |
audience, vote with your feet. Is it true or false? | 0:07:45 | 0:07:49 | |
Some frantic mind changing from some, then. I saw there was a bit of | 0:07:52 | 0:07:57 | |
mind changing from you. You suddenly decided no, it's true, yeah? | 0:07:57 | 0:08:00 | |
-Because it's very loud. -Yes. | 0:08:00 | 0:08:02 | |
So, it must be made by two. | 0:08:02 | 0:08:04 | |
-Oh, I see what you mean. -One could be very quiet. | 0:08:04 | 0:08:08 | |
Yeah, volume is one theory. What do you reckon? | 0:08:08 | 0:08:10 | |
I think it's false because | 0:08:10 | 0:08:13 | |
it might be where the owl might have big lungs. | 0:08:13 | 0:08:17 | |
-And it might make it loud. -So, owls have just got a loud voice. | 0:08:17 | 0:08:21 | |
-What do you reckon? Made by one owl or two owls? -One. | 0:08:21 | 0:08:24 | |
One owl. OK. Audience, thank you for your opinions. | 0:08:24 | 0:08:27 | |
Pop back to your places. | 0:08:27 | 0:08:29 | |
What do you think? The owl noise, "too wit too woo," | 0:08:29 | 0:08:32 | |
is actually made by two owls not just one. | 0:08:32 | 0:08:35 | |
-Do you think that's true or false? -False. | 0:08:35 | 0:08:37 | |
You think that's false. Oliver, | 0:08:37 | 0:08:39 | |
please tell us, is that true or false? | 0:08:39 | 0:08:43 | |
CAR HORN BEEPS | 0:08:43 | 0:08:44 | |
It's true. You said false. That means a green light to the Reds, | 0:08:44 | 0:08:48 | |
I'm sorry. The Reds get a green light. | 0:08:48 | 0:08:51 | |
It's tawny owls that make the "too wit too woo" noise, in fact, | 0:08:53 | 0:08:58 | |
and what we hear is a mixture of both the male | 0:08:58 | 0:09:00 | |
and female owls calling to each other. It's quite romantic. | 0:09:00 | 0:09:04 | |
Presumably one goes "too wit," and the other one goes "too woo". | 0:09:04 | 0:09:07 | |
Or something like that. Reds, this is now you in the same position | 0:09:07 | 0:09:12 | |
as the others were a moment ago. If you get this one right, | 0:09:12 | 0:09:15 | |
you get two green lights. You're in good form. | 0:09:15 | 0:09:18 | |
Get it wrong, and they can win it with their next question. | 0:09:18 | 0:09:21 | |
The longest woman's fingernail in the world is 90cm long. | 0:09:21 | 0:09:28 | |
Is that true or false? Have a think about it. | 0:09:28 | 0:09:30 | |
I'm not going to hurry you for an answer. | 0:09:30 | 0:09:32 | |
Audience, what do you think? Vote with your feet. Let's see. | 0:09:32 | 0:09:36 | |
So...90cm for the longest woman's fingernail in the world. | 0:09:42 | 0:09:46 | |
What do you think? Longest woman's fingernail, 90cm? | 0:09:46 | 0:09:49 | |
I think it might be longer because I saw something in the newspaper... | 0:09:49 | 0:09:53 | |
Longer found that? Oh, OK. And what do you think? | 0:09:53 | 0:09:55 | |
I think it's too long to be someone's fingernail. | 0:09:55 | 0:09:59 | |
How could it grow without breaking? | 0:09:59 | 0:10:01 | |
-It's too long. -OK, audience, if you'd like to | 0:10:01 | 0:10:03 | |
get back to your places, please. Now we know what you think, | 0:10:03 | 0:10:06 | |
we're interested in what the Reds think | 0:10:06 | 0:10:09 | |
because this is their question. | 0:10:09 | 0:10:11 | |
The longest woman's fingernail in the world is 90cm long. | 0:10:11 | 0:10:15 | |
-Is that true or false? -False. | 0:10:15 | 0:10:17 | |
False? OK. Oliver, is that true or false? | 0:10:17 | 0:10:21 | |
The Reds think it's false. | 0:10:21 | 0:10:23 | |
CAR HORN BEEPS | 0:10:23 | 0:10:24 | |
It's true! That means a second green light for the Yellows. | 0:10:24 | 0:10:28 | |
There you go. The record is held by an American, Lee Redmond. | 0:10:28 | 0:10:34 | |
She's not cut her nails since 1979. | 0:10:34 | 0:10:36 | |
I love your faces. That's exactly it. 1979! | 0:10:36 | 0:10:40 | |
Right, now the position is very interesting. | 0:10:40 | 0:10:42 | |
This is to stay in the game. This is pretty important. | 0:10:42 | 0:10:45 | |
Here comes your science fact. | 0:10:45 | 0:10:47 | |
House flies live, on average, for two years. | 0:10:47 | 0:10:52 | |
So, that's the science fact. | 0:10:52 | 0:10:54 | |
Is it a fact? Is it true, or is it false? | 0:10:54 | 0:10:57 | |
-False. -Oliver, for the game, is it true or false? | 0:10:57 | 0:11:02 | |
FOG HORN WAILS | 0:11:02 | 0:11:04 | |
It is false. That means another green light for the Yellows. | 0:11:04 | 0:11:08 | |
CHEERING AND APPLAUSE | 0:11:08 | 0:11:13 | |
In actual fact, house flies only have an average lifespan | 0:11:13 | 0:11:16 | |
of two weeks and usually spend most of it buzzing around my septic tank, | 0:11:16 | 0:11:20 | |
to be honest. Well done. It's 1-0 to the Yellows right now. | 0:11:20 | 0:11:23 | |
When I set out all those years ago | 0:11:39 | 0:11:41 | |
to build my very own time machine, I had no idea | 0:11:41 | 0:11:44 | |
that my never-before-seen splicing of science fact with science fiction | 0:11:44 | 0:11:49 | |
would lead to an often before seen result. Science failure. | 0:11:49 | 0:11:53 | |
I say failure, it did work. | 0:11:53 | 0:11:55 | |
Sort of, as the first person to use my time machine is about to prove. | 0:11:55 | 0:11:59 | |
That, of course, is Mini Miss. | 0:11:59 | 0:12:02 | |
APPLAUSE | 0:12:02 | 0:12:04 | |
The first person to use your time machine, Richard, | 0:12:09 | 0:12:12 | |
I'd like to suggest you also make that the last. | 0:12:12 | 0:12:14 | |
Yes, Miss. Sorry, Miss, about the whole... | 0:12:14 | 0:12:17 | |
She was my old science teacher and she still is my science teacher, | 0:12:17 | 0:12:20 | |
just that she's come out of my time machine as a 10-year-old. | 0:12:20 | 0:12:23 | |
I haven't got all day. Can we move on? | 0:12:23 | 0:12:26 | |
Yes, what's today's game all about? | 0:12:26 | 0:12:28 | |
Well, Richard, we'll be investigating friction | 0:12:28 | 0:12:30 | |
by playing a game I like to call... | 0:12:30 | 0:12:32 | |
I've seen curling. That's where they slide huge lumps of granite | 0:12:35 | 0:12:38 | |
along the ice, like that. | 0:12:38 | 0:12:40 | |
I've often thought, why not use smaller lumps of granite? | 0:12:40 | 0:12:43 | |
It would make it easier. You could go a lot further. | 0:12:43 | 0:12:46 | |
Yes, and another way to make it easier | 0:12:46 | 0:12:48 | |
would be to replace the ice with a sheet of Teflon, | 0:12:48 | 0:12:51 | |
one of the slipperiest man-made substances on the planet. | 0:12:51 | 0:12:55 | |
That's what we've got here. A huge slide of the slippy substance. | 0:12:55 | 0:12:59 | |
And in the background, we have these objects. So, each team has to choose | 0:12:59 | 0:13:03 | |
an object and then put it in a giant frying pan, | 0:13:03 | 0:13:06 | |
and attempt to slide them along the slippery surface | 0:13:06 | 0:13:09 | |
into these scores zones. | 0:13:09 | 0:13:11 | |
But, don't push too hard or the frying-pan will slip off the end | 0:13:11 | 0:13:15 | |
and into the fire and you'll get no score at all for your push. | 0:13:15 | 0:13:19 | |
What we've got is our super slippery surface, | 0:13:19 | 0:13:21 | |
which means we've kept friction down to a minimum. | 0:13:21 | 0:13:24 | |
What you guys have to do, teams, | 0:13:24 | 0:13:26 | |
is give the right amount of momentum to the frying pan with your chosen | 0:13:26 | 0:13:29 | |
object, so it slides down to the highest score possible before | 0:13:29 | 0:13:33 | |
the bit of friction that is here actually makes it come to a stop. | 0:13:33 | 0:13:37 | |
This is a game of skill and judgment. | 0:13:37 | 0:13:39 | |
You're judging the amount of momentum required. | 0:13:39 | 0:13:42 | |
Good luck with that. OK, let's go on with the game. | 0:13:42 | 0:13:44 | |
Yellow Team, you one Fact Nav, you are ahead so you get to decide | 0:13:44 | 0:13:48 | |
if you want to go first or second. | 0:13:48 | 0:13:50 | |
Could we go second, please? | 0:13:50 | 0:13:52 | |
OK. Reds are going first, Let's get on with it. | 0:13:52 | 0:13:55 | |
Good luck both teams. Here we go. | 0:13:55 | 0:13:56 | |
The Reds have been forced to go first and they've chosen the egg. | 0:13:59 | 0:14:03 | |
AUDIENCE: Ooh... | 0:14:05 | 0:14:07 | |
APPLAUSE | 0:14:07 | 0:14:11 | |
That's three points for the Reds. | 0:14:11 | 0:14:13 | |
Now, it's round one for the Yellows and they've gone for the burger. | 0:14:13 | 0:14:16 | |
Will this fast food live up to its name? | 0:14:16 | 0:14:20 | |
APPLAUSE | 0:14:24 | 0:14:26 | |
Wow, nice call. | 0:14:26 | 0:14:28 | |
That's five points for the Yellows. Good shot. | 0:14:28 | 0:14:32 | |
They're going for the sausage. | 0:14:34 | 0:14:37 | |
What? It's sausage. Good luck, Reds. | 0:14:37 | 0:14:40 | |
APPLAUSE | 0:14:43 | 0:14:45 | |
That's four points for the Reds. | 0:14:45 | 0:14:48 | |
Yellows now choosing tomatoes. Can they beat what has gone before? | 0:14:51 | 0:14:56 | |
Jacob trying to judge the momentum needed | 0:14:56 | 0:14:58 | |
to score the most without going into the fire. | 0:14:58 | 0:15:01 | |
Ooh! | 0:15:01 | 0:15:04 | |
The Yellows showing us how it should be done with | 0:15:04 | 0:15:07 | |
-a perfect score. -So that's seven points for the Yellows. | 0:15:07 | 0:15:13 | |
It's not looking good for the Reds. They only have seven points | 0:15:13 | 0:15:17 | |
to the Yellows' 12. They're going to need to get a maximum score | 0:15:17 | 0:15:20 | |
to stand any chance of winning this game. | 0:15:20 | 0:15:24 | |
It's a four. Still a good score. Good, safe score. Well done. | 0:15:28 | 0:15:32 | |
-That's four points for the Reds. -With that last effort, it is now | 0:15:32 | 0:15:38 | |
impossible for the Reds to win. | 0:15:38 | 0:15:41 | |
The Yellows still have one more go, though, | 0:15:41 | 0:15:43 | |
with the final item, the bacon. Here we go. | 0:15:43 | 0:15:45 | |
APPLAUSE | 0:15:48 | 0:15:53 | |
That's four points for the Yellows. | 0:15:53 | 0:15:56 | |
Right, teams, we have finished. | 0:15:56 | 0:15:57 | |
We have slid everything that we have to slide. | 0:15:57 | 0:16:00 | |
And I can tell you that the... | 0:16:00 | 0:16:01 | |
Well, here are the scores. Reds, you got 11, Yellows, 16. | 0:16:01 | 0:16:06 | |
That means it's now 2-0 to the Yellows! Well done! | 0:16:06 | 0:16:09 | |
It was a game of judgment, how much momentum to give it. | 0:16:11 | 0:16:15 | |
Sorry. Don't worry, it's not over yet, Reds. | 0:16:15 | 0:16:17 | |
All that sliding around was a bit fast-paced for me. | 0:16:17 | 0:16:20 | |
My excitement-o-meter is measuring off the chart, | 0:16:20 | 0:16:23 | |
by which I mean my heart's beating way too fast and I feel a bit sick. | 0:16:23 | 0:16:27 | |
I think it's time we slowed things down a bit. | 0:16:27 | 0:16:29 | |
Meet Slow Rider. | 0:16:35 | 0:16:38 | |
This bad boy believes everything in life is better when done slowly. | 0:16:38 | 0:16:42 | |
In fact, he's been living such a slowed-down life | 0:16:42 | 0:16:45 | |
that he's developed the knack of viewing everyday occurrences | 0:16:45 | 0:16:48 | |
in slow motion. | 0:16:48 | 0:16:49 | |
Today, we've brought in a special slow-motion camera | 0:16:49 | 0:16:53 | |
which will let us into his secret world of slowness. | 0:16:53 | 0:16:56 | |
We'll be able to see things 40 times slower than they really are | 0:16:56 | 0:17:00 | |
and find out just why he loves things going so slowly. | 0:17:00 | 0:17:03 | |
We're using a camera that captures 40 times more images per second | 0:17:03 | 0:17:08 | |
than the human eye, allowing us to see things as they actually happen | 0:17:08 | 0:17:11 | |
rather than how we think they do. So, what's first on the menu? | 0:17:11 | 0:17:15 | |
A lab rat eating a lemon. | 0:17:15 | 0:17:17 | |
Well, Slow Rider seemed impressed. | 0:17:21 | 0:17:23 | |
Let's take a closer look. | 0:17:23 | 0:17:25 | |
Yeah, it is disgusting, but for some reason it's hard not to look. | 0:17:33 | 0:17:37 | |
Next, a man with a fish. | 0:17:41 | 0:17:44 | |
Amazing. | 0:17:51 | 0:17:53 | |
Even on what is one of the slimmer lab rats, you can clearly see | 0:17:53 | 0:17:56 | |
the skin rippling from the point of fish-on-face impact. | 0:17:56 | 0:18:01 | |
What now? | 0:18:01 | 0:18:03 | |
Two cream cakes. Ooh, I think I can see what's coming here. | 0:18:03 | 0:18:08 | |
Comic genius. Now, let's take a look at that in slow motion. | 0:18:08 | 0:18:12 | |
OK, all very entertaining, but this is Blast Lab, | 0:18:24 | 0:18:27 | |
so it's time for an experiment. | 0:18:27 | 0:18:29 | |
One lab rat and a balloon filled with water. | 0:18:29 | 0:18:33 | |
When popped and watched at normal speed, it looks like this. | 0:18:33 | 0:18:38 | |
All a bit messy. But what is happening? | 0:18:38 | 0:18:41 | |
I feel a science graphic coming on. | 0:18:41 | 0:18:43 | |
When the balloon is popped, there are several forces | 0:18:43 | 0:18:46 | |
acting on the water, each affecting its shape and how it falls. | 0:18:46 | 0:18:50 | |
First, there's gravity, which should | 0:18:50 | 0:18:52 | |
pull each and every water molecule towards the ground at the same rate, | 0:18:52 | 0:18:56 | |
making the water keep the exact shape of the balloon. | 0:18:56 | 0:18:59 | |
Second, there's surface tension. This is made by the water molecules | 0:18:59 | 0:19:02 | |
being sticky and clinging to each other. | 0:19:02 | 0:19:05 | |
This surface tension acts to make the water a perfect ball shape. | 0:19:05 | 0:19:09 | |
Finally, there's air resistance. | 0:19:09 | 0:19:11 | |
This pushes on the water molecules as they fall through the air, | 0:19:11 | 0:19:15 | |
making them spread out in all directions. | 0:19:15 | 0:19:18 | |
OK, so there are three forces that can change the water's shape. | 0:19:18 | 0:19:22 | |
When you watch the balloon burst with your own eyes, | 0:19:22 | 0:19:24 | |
it's impossible to see what they actually do to the water. | 0:19:24 | 0:19:28 | |
Let's watch it again, only this time with our special slow-motion camera. | 0:19:28 | 0:19:32 | |
Will we see the water keep the shape of the balloon as it's popped, | 0:19:32 | 0:19:36 | |
or will the water splash everywhere? | 0:19:36 | 0:19:38 | |
OK, hold the experiment. There is a point up for grabs here, teams. | 0:19:39 | 0:19:43 | |
The score is 2-0, I know, so you can't suddenly | 0:19:43 | 0:19:46 | |
take the lead, but it'd be nice to win the point. | 0:19:46 | 0:19:49 | |
I will give the point to the team that can tell me most accurately | 0:19:49 | 0:19:52 | |
what happens. What do we think? | 0:19:52 | 0:19:54 | |
Will the water be able to hold its shape? | 0:19:54 | 0:19:57 | |
Yellows? | 0:19:57 | 0:19:58 | |
-What do you think? -I think we'll be able to see it hold its shape. | 0:19:58 | 0:20:01 | |
So you think just a balloon shape. | 0:20:01 | 0:20:03 | |
-OK. Reds, what do you reckon? -We think the same, it'll keep its shape. | 0:20:03 | 0:20:07 | |
Let's find out. There's only one way to do that. On with the experiment. | 0:20:07 | 0:20:11 | |
So, we all think we know what happens | 0:20:11 | 0:20:14 | |
when you pop a water balloon. | 0:20:14 | 0:20:16 | |
But what REALLY happens? | 0:20:16 | 0:20:18 | |
Let's find out. | 0:20:18 | 0:20:20 | |
As the balloon breaks, some water droplets explode outwards, | 0:20:34 | 0:20:38 | |
but the main bulk of the water | 0:20:38 | 0:20:40 | |
actually holds the shape of the balloon before dropping. | 0:20:40 | 0:20:43 | |
So there you have it. | 0:20:49 | 0:20:51 | |
Water does actually hold the shape when it comes out of the balloon. | 0:20:51 | 0:20:56 | |
That means it's a point to both teams. | 0:20:56 | 0:20:58 | |
-Well done. Absolutely. Yeah. -CHEERING AND APPLAUSE | 0:20:58 | 0:21:02 | |
Er... All right, you can have it back. Thank you, Michael. | 0:21:03 | 0:21:07 | |
Erm, I just like popcorn. Thanks very much. | 0:21:07 | 0:21:10 | |
Both teams get a point from that. The score now is 3-1. | 0:21:10 | 0:21:13 | |
Reds and Yellows, away you go and get changed. | 0:21:13 | 0:21:15 | |
CHEERING AND APPLAUSE | 0:21:15 | 0:21:18 | |
It's good, though. It's salty. | 0:21:18 | 0:21:20 | |
It's nice. That got my lab rats thinking, | 0:21:20 | 0:21:23 | |
that experiment, though they don't think normally, like the rest of us. | 0:21:23 | 0:21:27 | |
Looks like Slow Rider has taken his leave. | 0:21:27 | 0:21:30 | |
A lab rat in charge of an expensive piece of camera equipment? | 0:21:30 | 0:21:34 | |
Now, that's a recipe for disaster if I ever saw one. | 0:21:34 | 0:21:37 | |
Slow motion of a ball being kicked, eh? Well, let's see what happens. | 0:21:37 | 0:21:41 | |
You can see the ball compressing against the foot | 0:21:41 | 0:21:43 | |
before shooting off. | 0:21:43 | 0:21:46 | |
Very impressive. I take it all back. | 0:21:46 | 0:21:48 | |
Ah, he's hit the camera. Wait till I get my hands on you. | 0:21:48 | 0:21:50 | |
All right. And now it's time for... | 0:21:50 | 0:21:55 | |
In that tank with you are pieces of a bridge - a bridge better known as | 0:21:58 | 0:22:01 | |
the Bridge of Destiny. | 0:22:01 | 0:22:03 | |
DRAMATIC, AMERICAN ACCENT: The Bridge of Destiny! | 0:22:03 | 0:22:06 | |
You have to find all the pieces you can | 0:22:06 | 0:22:08 | |
in that gunge to make the bridge to drive your cars across. | 0:22:08 | 0:22:11 | |
It's that simple. The team that crosses it first | 0:22:11 | 0:22:14 | |
will win all the prizes in the car's trailer - | 0:22:14 | 0:22:16 | |
like radio-controlled spider, bionic copter. | 0:22:16 | 0:22:19 | |
You'll win one of those each. Know what you're doing? | 0:22:19 | 0:22:22 | |
-Yeah. -If we're ready, let's play the Bridge of Destiny. | 0:22:22 | 0:22:25 | |
HIGH-PITCHED: # The Bridge of Destiny! # | 0:22:25 | 0:22:29 | |
HE HOLDS THE NOTE | 0:22:29 | 0:22:34 | |
Yellow Team, you're in the lead right now, | 0:22:35 | 0:22:38 | |
so you get the five-second head start. | 0:22:38 | 0:22:40 | |
Reds, you go on the second siren, not before, OK? Everybody know | 0:22:40 | 0:22:44 | |
what they're doing? Good luck in the race to get your cars across. | 0:22:44 | 0:22:47 | |
Let's start...now! | 0:22:47 | 0:22:49 | |
And it's the Yellows who have the advantage, | 0:22:49 | 0:22:52 | |
but will they make it count? | 0:22:52 | 0:22:55 | |
There go the Reds. | 0:22:55 | 0:22:56 | |
It's a battle out there today, with neither team taking prisoners. | 0:22:56 | 0:23:00 | |
No time for pleasantries in this game. | 0:23:00 | 0:23:03 | |
Both teams struggling to impose themselves at the moment, | 0:23:03 | 0:23:06 | |
opting for the "square peg in a round hole" tactic, | 0:23:06 | 0:23:09 | |
which, I can tell you, | 0:23:09 | 0:23:10 | |
has not been the most successful technique in times past. | 0:23:10 | 0:23:14 | |
There's certainly no lack of effort on display today. | 0:23:14 | 0:23:18 | |
Hard to tell who's doing best - or who's doing worst - | 0:23:18 | 0:23:21 | |
with both teams desperately trying to build a bridge | 0:23:21 | 0:23:24 | |
maybe as slowly as possible. | 0:23:24 | 0:23:27 | |
I did explain the rules, didn't I? Did I? | 0:23:27 | 0:23:30 | |
And as if things weren't bad enough, | 0:23:30 | 0:23:33 | |
that sounds like my sickly robot Alan about to sneeze. | 0:23:33 | 0:23:37 | |
Lovely. Why is it blue? Please don't write in. | 0:23:37 | 0:23:40 | |
I don't want to know. Back to the game. | 0:23:40 | 0:23:42 | |
Has there been any progress whatsoever? | 0:23:42 | 0:23:46 | |
Well, yes, both teams seem to have woken from their slumber | 0:23:46 | 0:23:49 | |
and are desperately close to finishing their bridges. | 0:23:49 | 0:23:51 | |
It really is anyone's game now. | 0:23:51 | 0:23:54 | |
And I think the Yellows might have the edge, | 0:23:54 | 0:23:57 | |
but it's too close to call. | 0:23:57 | 0:23:59 | |
Oh, not again. Alan's about to add to the confusion. | 0:23:59 | 0:24:02 | |
Oh, thanks so much for your input, Alan(!) Always welcome. | 0:24:05 | 0:24:08 | |
This is the closest finish I've ever seen. Red? Yellow? I don't know! | 0:24:09 | 0:24:12 | |
The crowd doesn't know. | 0:24:12 | 0:24:14 | |
It's Yellows that have pulled their lever first | 0:24:16 | 0:24:18 | |
to release the prize wagon. | 0:24:18 | 0:24:20 | |
Will it slip? It's slipping, it's slipping, but it's over. | 0:24:20 | 0:24:23 | |
A majestic win for the Yellows. Bad luck, Reds. | 0:24:23 | 0:24:27 | |
Yeah, I'd say, Yellows, | 0:24:27 | 0:24:29 | |
you got your car safely across the bridge, and then some! | 0:24:29 | 0:24:32 | |
While we pick those up, that can be only one result, then. | 0:24:32 | 0:24:35 | |
It's a win for the Yellows! Well done! | 0:24:35 | 0:24:37 | |
CHEERING AND APPLAUSE | 0:24:37 | 0:24:40 | |
Let's have a look at what you've won. Are you ready? | 0:24:40 | 0:24:44 | |
Each of you will take home Tomb of Doom, | 0:24:44 | 0:24:47 | |
Bionic Copter, | 0:24:47 | 0:24:50 | |
Lunar Eclipse Bedroom Light, | 0:24:50 | 0:24:53 | |
a puzzle cube for each of you, | 0:24:53 | 0:24:56 | |
radio-controlled spider for each of you, | 0:24:56 | 0:25:00 | |
flying UFO, | 0:25:00 | 0:25:02 | |
bouncy balls, | 0:25:02 | 0:25:05 | |
and a metal detector. | 0:25:05 | 0:25:07 | |
CHEERING AND APPLAUSE | 0:25:07 | 0:25:09 | |
That's all great news on this side of the tank. | 0:25:09 | 0:25:11 | |
Over here, slightly different. Unlucky, losing team. | 0:25:11 | 0:25:14 | |
Funnily, you would actually have won exactly the same prizes. | 0:25:14 | 0:25:18 | |
You'd each have taken home all of those. | 0:25:18 | 0:25:20 | |
But of course, only one team can go home with their prizes, | 0:25:20 | 0:25:23 | |
the other goes home with what they came with - nothing. | 0:25:23 | 0:25:27 | |
Because it's time for Bidet Goes Bang! | 0:25:27 | 0:25:29 | |
Well done. Fair enough. | 0:25:36 | 0:25:39 | |
So, two teams of brothers and sisters came to the Blast Lab - | 0:25:39 | 0:25:43 | |
one, the Yellows, leaving happily with all of these prizes. | 0:25:43 | 0:25:46 | |
These are all yours. Yeah, feeling good! Yeah, right, well done! | 0:25:46 | 0:25:50 | |
CHEERING AND APPLAUSE | 0:25:50 | 0:25:51 | |
Congratulations. The other team of brothers and sisters, | 0:25:51 | 0:25:54 | |
the Reds, it's a different mood going on, | 0:25:54 | 0:25:58 | |
because you did really well all the way through. You were great sports. | 0:25:58 | 0:26:01 | |
And then you lost. I'm really sorry, | 0:26:01 | 0:26:03 | |
and so it is with a heavy heart that I must ask you to do this. | 0:26:03 | 0:26:06 | |
I say heavy heart - it could just be indigestion. Either way, follow me. | 0:26:06 | 0:26:10 | |
It's time for the Walk of Shame. Let's do it. | 0:26:10 | 0:26:13 | |
Thank you, audience. | 0:26:13 | 0:26:15 | |
-SAD MUSIC PLAYS -Oh! It's sad. | 0:26:15 | 0:26:18 | |
Oh, it's heartbreaking. | 0:26:22 | 0:26:25 | |
It is sad. | 0:26:26 | 0:26:28 | |
OK. | 0:26:31 | 0:26:32 | |
Reds, there's no nice way of putting this, really. You lost. | 0:26:34 | 0:26:37 | |
What you're going to do instead of taking your prizes is... | 0:26:37 | 0:26:40 | |
-Blow them up. -..blow 'em up, yeah, that's what we're going to do. | 0:26:40 | 0:26:43 | |
You played really well all through. Hope you enjoyed it. | 0:26:43 | 0:26:46 | |
I'm sorry you couldn't win. | 0:26:46 | 0:26:48 | |
So, if you'd like to lift the plunger... | 0:26:48 | 0:26:50 | |
-Yes! -..united as a family team, | 0:26:50 | 0:26:53 | |
sharing the blame together for blowing to bits | 0:26:53 | 0:26:56 | |
all the prizes they'd love to take home. | 0:26:56 | 0:26:58 | |
If we're ready, audience, let's count them down. From five... | 0:26:58 | 0:27:01 | |
AUDIENCE: Four, three, two, one! | 0:27:01 | 0:27:04 | |
Well, today has been a good day. | 0:27:13 | 0:27:16 | |
We've learnt about friction by putting objects in giant frying pans | 0:27:16 | 0:27:19 | |
and studied some frankly funny phenomena in slow motion. | 0:27:19 | 0:27:22 | |
So from the lab rats and me, it's goodbye. | 0:27:22 | 0:27:25 | |
Actually, the lab rats have barely noticed the show's even started, | 0:27:25 | 0:27:28 | |
so it's just goodbye from me, really. Goodbye! | 0:27:28 | 0:27:31 | |
