I think just a tiny bit more of this, and we should have it about... | 0:00:34 | 0:00:37 | |
here! | 0:00:37 | 0:00:39 | |
I meant that. That's how that was supposed to go. | 0:00:41 | 0:00:43 | |
POLICE SIRENS | 0:00:43 | 0:00:45 | |
Yeah, they're turning up just to look because it was so interesting. | 0:00:45 | 0:00:48 | |
Anyway, hello! | 0:00:48 | 0:00:50 | |
I'm Richard, and this is my Blast Lab, my top-secret science facility. | 0:00:53 | 0:00:57 | |
If any of you mention this place to your parents, I'll come over | 0:00:57 | 0:01:00 | |
to your house and gunge you for reasons of national security. | 0:01:00 | 0:01:04 | |
I've invited two carefully selected teams to take on | 0:01:04 | 0:01:07 | |
a series of scientific challenges. The team with the greatest skill, | 0:01:07 | 0:01:10 | |
knowledge and intelligence will be walking away with exciting prizes. | 0:01:10 | 0:01:14 | |
Let's see what's in store today. | 0:01:14 | 0:01:16 | |
I usually have a crack team of SAS officers guarding this lab | 0:01:29 | 0:01:33 | |
from intruders, but they cancelled at the last minute today, because | 0:01:33 | 0:01:37 | |
apparently they need to do some electrical work back at the SAS HQ. | 0:01:37 | 0:01:42 | |
How many SAS men does it take to change a light bulb? | 0:01:42 | 0:01:45 | |
Well, 12 apparently. | 0:01:45 | 0:01:46 | |
Luckily for me, I have a relative who's trained in martial arts. | 0:01:46 | 0:01:49 | |
It's not my judo brother or karate mum, it is my Ninja Nan. | 0:01:49 | 0:01:54 | |
CHEERING AND APPLAUSE | 0:01:54 | 0:01:56 | |
Ninja Nan. Thanks for standing in. | 0:02:05 | 0:02:08 | |
She might look fragile, but she's a fully-trained Ninja. | 0:02:08 | 0:02:11 | |
THWACKS AND SLAPS | 0:02:11 | 0:02:15 | |
Yeah. Take your place in security, please, Nan. | 0:02:15 | 0:02:18 | |
Nan! Take your place in security. Thank you. Thank you. | 0:02:18 | 0:02:21 | |
Don't make any sudden movements when she's around | 0:02:21 | 0:02:25 | |
or she'll be on you like a cheetah. | 0:02:25 | 0:02:27 | |
Not one of those fast cheetahs, a slow, but lethal, cheetah. | 0:02:27 | 0:02:31 | |
There she goes. | 0:02:31 | 0:02:33 | |
She is deadly, though. She is! Nan, are you settled into security yet? | 0:02:33 | 0:02:38 | |
Are you in position? There she is. | 0:02:38 | 0:02:41 | |
She'll get settled into her security chair. Sorry, into her Ninja bag | 0:02:41 | 0:02:45 | |
for Ninja knitting. Keeps her occupied. Stops her being dangerous. | 0:02:45 | 0:02:49 | |
While she gets her knitting going, let's have a look at who's | 0:02:49 | 0:02:52 | |
trying to get into my lab today. It should be a bunch of people. | 0:02:52 | 0:02:57 | |
Yeah, yeah, yeah, you see. You applaud. | 0:02:57 | 0:02:59 | |
You guys all say you're the Yellow Team, don't you? | 0:02:59 | 0:03:02 | |
But are you? We can't be too sure. This is a top-secret lab. | 0:03:02 | 0:03:05 | |
So before I can let you through security I have to run | 0:03:05 | 0:03:08 | |
some checks on you from my security file. | 0:03:08 | 0:03:10 | |
-Identify yourselves by name, please. -Alice. -William. -Bethan. | 0:03:10 | 0:03:14 | |
Alice. William. Bethan. That checks out with what I've got here. | 0:03:14 | 0:03:18 | |
It also says on your security file, hidden talent, | 0:03:18 | 0:03:23 | |
-Bethan, you can use your foot as a telephone? -Yeah, I can. | 0:03:23 | 0:03:27 | |
Go on, then. If you'd do that for us. | 0:03:27 | 0:03:30 | |
Ding, a-ding, a-ling. Hello? | 0:03:30 | 0:03:32 | |
That's her foot used as a phone. You're cleared through security. | 0:03:32 | 0:03:36 | |
Come through to the lab, please. Mind Ninja Nan. Ready to spring. | 0:03:36 | 0:03:41 | |
Welcome. That confirms it, then. You are cleared through security. | 0:03:41 | 0:03:45 | |
You are our Yellow Team. Where are you from? | 0:03:45 | 0:03:47 | |
ALL: Isle of Wight and we are... | 0:03:47 | 0:03:51 | |
# ABW Question mark. # | 0:03:51 | 0:03:55 | |
Good grief. You've worked out a name and a dance. Waste of time, really. | 0:03:55 | 0:03:59 | |
You are the Yellow Team. That's that. Welcome to the lab. | 0:03:59 | 0:04:02 | |
There should somewhere in there be a bunch of people | 0:04:02 | 0:04:05 | |
claiming to be the Red Team. Hello. | 0:04:05 | 0:04:07 | |
CHEERING AND APPLAUSE | 0:04:07 | 0:04:10 | |
Don't get excited, they could be anybody. Let's prove they are | 0:04:10 | 0:04:13 | |
-who they say. Identify yourselves. -Elena. -Nathan. -Josh. | 0:04:13 | 0:04:18 | |
Elena. Nathan. Josh. That checks out. Now, your hidden talent. | 0:04:18 | 0:04:22 | |
It says here, Josh, you're going to do something for us but, | 0:04:22 | 0:04:25 | |
hold on, don't move a muscle. | 0:04:25 | 0:04:27 | |
It says you can do martial arts. With Ninja Nan in the room anything | 0:04:27 | 0:04:31 | |
could happen. I've got a Lab Rat securing her, cordoning her off. | 0:04:31 | 0:04:36 | |
I reckon you're safe to demonstrate your martial arts | 0:04:36 | 0:04:39 | |
-without being torn apart by Ninja Nan. -What can you do for us? | 0:04:39 | 0:04:44 | |
Ooh. Ooh, right. I'd say that's some martial arts right there. | 0:04:44 | 0:04:48 | |
You're cleared through security. Come on in. | 0:04:48 | 0:04:50 | |
CHEERING AND APPLAUSE | 0:04:50 | 0:04:55 | |
Josh, it's difficult to describe the danger you were in with Ninja Nan. | 0:04:55 | 0:04:59 | |
Did you not sense the martial presence of her? | 0:04:59 | 0:05:01 | |
OK, she keeps it well hidden. She really does. | 0:05:01 | 0:05:04 | |
Welcome to the Blast Lab. Where are you from? | 0:05:04 | 0:05:06 | |
-ALL: Mansfield, and we are... -N... -E... -...J. -ALL:Woo! | 0:05:06 | 0:05:10 | |
That's elaborate and unnecessary because you are the Red Team. | 0:05:10 | 0:05:14 | |
That's your team name. Welcome to the lab. Both teams, | 0:05:14 | 0:05:17 | |
time for you to get into position, ready for the first game. | 0:05:17 | 0:05:20 | |
Go and make yourselves comfortable. To help me with the first round | 0:05:20 | 0:05:23 | |
I'd like to welcome a special friend of mine. It is Oliver. | 0:05:23 | 0:05:27 | |
Oliver has the very latest state of the art | 0:05:44 | 0:05:47 | |
factual navigation system, or FACTNAV for short, | 0:05:47 | 0:05:50 | |
designed to be the smartest on board science computer ever seen. | 0:05:50 | 0:05:54 | |
But I built it myself and I think I wired something up wrong, | 0:05:54 | 0:05:57 | |
because every now and then it comes up with a fact | 0:05:57 | 0:06:00 | |
that is totally false. | 0:06:00 | 0:06:02 | |
Thankfully, Oliver knows what's what and can spot the porky pies. | 0:06:02 | 0:06:05 | |
The thing is, can our two teams? | 0:06:05 | 0:06:08 | |
So I will give each team a fact. | 0:06:08 | 0:06:10 | |
If it is true, Oliver will do this. | 0:06:10 | 0:06:12 | |
HORNS AND SIRENS | 0:06:12 | 0:06:15 | |
And if it's false, Oliver will do this. | 0:06:15 | 0:06:17 | |
FOGHORN | 0:06:17 | 0:06:19 | |
OK, teams. It's clear enough, I think. | 0:06:19 | 0:06:21 | |
You understand the rules here. Right, one fact each. | 0:06:21 | 0:06:24 | |
Red, you're going first. | 0:06:24 | 0:06:26 | |
Here's your fact, tell me whether this is true or false. | 0:06:26 | 0:06:29 | |
A trillion tonnes of the world's water | 0:06:29 | 0:06:32 | |
evaporates each day in the sun. | 0:06:32 | 0:06:35 | |
Evaporates? Have a chat and a think. Work it out. You never know what one | 0:06:36 | 0:06:40 | |
of you might know that might help. I'll ask the audience if it is | 0:06:40 | 0:06:43 | |
true or false. What do you think? | 0:06:43 | 0:06:45 | |
SHOUTING | 0:06:45 | 0:06:49 | |
A fair few trues, but quite a few false there as well. | 0:06:49 | 0:06:52 | |
A few not believing that. Down here, what do we think? True or false? | 0:06:52 | 0:06:56 | |
OK, I reckon it's a mixed bag from the audience. | 0:06:56 | 0:06:58 | |
Don't go by them anyway, because...well, look at them. | 0:06:58 | 0:07:02 | |
What do you think for yourselves? | 0:07:02 | 0:07:04 | |
-We think true. -You think it's true that a trillion tonnes of the | 0:07:04 | 0:07:07 | |
world's water does evaporate every day in the sun. | 0:07:07 | 0:07:10 | |
Oliver, is it true or false? | 0:07:10 | 0:07:12 | |
HORNS AND SIRENS | 0:07:12 | 0:07:14 | |
It's true! That is your first point. Well done. Moist air rises. | 0:07:14 | 0:07:17 | |
As the air cools, water vapour begins to condense out of it. | 0:07:17 | 0:07:20 | |
That's where clouds come from. | 0:07:20 | 0:07:22 | |
After the water droplets get too big to stay in the cloud, | 0:07:22 | 0:07:25 | |
they become heavier. They can collide with each other. | 0:07:25 | 0:07:28 | |
That causes rain. Or to give it's posh name, precipitation. | 0:07:28 | 0:07:32 | |
OK, Yellow Team, here comes your science fact. | 0:07:32 | 0:07:35 | |
Is this true or false? | 0:07:35 | 0:07:37 | |
A bolt of lightning is so hot | 0:07:37 | 0:07:40 | |
that if it hits sand, it can turn it into glass. | 0:07:40 | 0:07:44 | |
A bolt of lightning hits sand, it can turn the sand into glass. | 0:07:44 | 0:07:49 | |
Have a chat. A think. Everything you think might help, discuss it. | 0:07:49 | 0:07:52 | |
Meanwhile, audience, what do you think? True or false? | 0:07:52 | 0:07:56 | |
SHOUTING | 0:07:56 | 0:07:58 | |
A real mixed bag again. | 0:07:58 | 0:08:00 | |
No obvious real help from the audience. What do you think? | 0:08:00 | 0:08:03 | |
-True. -You think it's true? You think that if a bolt of lightning | 0:08:03 | 0:08:06 | |
hits the sand it does turn it into glass. Oliver, is it true or false? | 0:08:06 | 0:08:10 | |
HORNS AND SIRENS | 0:08:10 | 0:08:12 | |
It's true! That's a point for Yellow Team as well. Well done. | 0:08:12 | 0:08:15 | |
Actually, it makes glass rods in the sand, called fulgurites. | 0:08:15 | 0:08:20 | |
They can be all knobbly, like branches, and the amount of energy | 0:08:20 | 0:08:23 | |
required to do that? Estimates vary. But the temperature, they reckon, | 0:08:23 | 0:08:27 | |
could be 4,000 degrees C. So it's really toasty. | 0:08:27 | 0:08:30 | |
One last question for both teams. This time it really is a question. | 0:08:30 | 0:08:34 | |
I don't want you to tell me if this is true or false, just an answer. | 0:08:34 | 0:08:37 | |
Write it down on these boards | 0:08:37 | 0:08:39 | |
and I will give a point to whichever team is closest to the answer. | 0:08:39 | 0:08:44 | |
If you were to drive a car at 60mph towards the sun, for 24 hours a day, | 0:08:44 | 0:08:51 | |
how long would it take you to reach the sun? | 0:08:51 | 0:08:54 | |
Have a chat, have a think. If you were to drive a car 60mph | 0:08:54 | 0:08:57 | |
for 24 hours, how long would it take you to reach the sun? | 0:08:57 | 0:09:03 | |
Audience, any suggestions for that? | 0:09:03 | 0:09:05 | |
I'll bring my mug-tree mic. It's disguised. | 0:09:05 | 0:09:08 | |
Still, nobody likes it. What do you think? | 0:09:08 | 0:09:12 | |
Is it a trick question? | 0:09:12 | 0:09:14 | |
So you don't trust me? You come to my lab and you don't trust me. | 0:09:14 | 0:09:18 | |
How can it be a trick question? Because there is no road to the sun? | 0:09:18 | 0:09:23 | |
You have a very good point. But it's not a trick question. | 0:09:23 | 0:09:26 | |
There is an answer. Yes? | 0:09:26 | 0:09:28 | |
It would be over 1,500 miles. | 0:09:28 | 0:09:31 | |
I need it in time. I need time. | 0:09:31 | 0:09:33 | |
How long it would take. | 0:09:33 | 0:09:36 | |
I need this answer. Here's a clue. | 0:09:36 | 0:09:39 | |
It's in years, quite a long time. What do you think? | 0:09:39 | 0:09:43 | |
Would you die on the way? | 0:09:43 | 0:09:44 | |
Yes, you'd get really hot. | 0:09:44 | 0:09:46 | |
I'm not suggesting that you jump in Oliver and drive to the sun. | 0:09:46 | 0:09:51 | |
But how long do you reckon in years? Really hot... | 0:09:51 | 0:09:54 | |
Ten years? | 0:09:54 | 0:09:56 | |
Ten years? It's a tricky one. | 0:09:56 | 0:09:58 | |
To be honest, I don't know the answer off the top of my head. | 0:09:58 | 0:10:01 | |
-I would probably be impossible. -Look, can we establish, audience, | 0:10:01 | 0:10:05 | |
I know it's tricky! I'm not suggesting we all set off for | 0:10:05 | 0:10:08 | |
the sun on holiday. Theoretically. | 0:10:08 | 0:10:10 | |
That means we're not actually going to do it, but theoretically. | 0:10:10 | 0:10:14 | |
The distance the sun is from the earth is the key factor. | 0:10:14 | 0:10:17 | |
How long would it take to drive there? | 0:10:17 | 0:10:19 | |
We're not going to get an accurate answer here. | 0:10:19 | 0:10:22 | |
Maybe we will, though, from our teams. Are you feeling clever? | 0:10:22 | 0:10:26 | |
Good, right. I need some answers, then. Let's have a look. | 0:10:26 | 0:10:30 | |
In years, how long do you think? | 0:10:30 | 0:10:32 | |
Reds, you've written down five years. | 0:10:32 | 0:10:34 | |
Yellows, you've written down 950 years. | 0:10:34 | 0:10:37 | |
Quite a range in your answers there, from five years to 950. | 0:10:37 | 0:10:41 | |
The real answer is... | 0:10:41 | 0:10:43 | |
It would take you 177 years, which means the Red Team win the point. | 0:10:43 | 0:10:49 | |
Well done. | 0:10:49 | 0:10:51 | |
If you were thinking of going, anybody, it's actually | 0:10:51 | 0:10:55 | |
1,550,520 hours of driving, because earth is, more or less, | 0:10:55 | 0:11:01 | |
92,955,807.3 miles from the sun. | 0:11:01 | 0:11:07 | |
That means Red Team is in the lead. Two points to Yellows' one. | 0:11:07 | 0:11:11 | |
Well done to both teams. | 0:11:11 | 0:11:13 | |
That's all to come. Right now, it's time to play Mini Science. | 0:11:29 | 0:11:33 | |
Our contestants will use household objects to conduct complex | 0:11:33 | 0:11:37 | |
scientific experiments. To help me is my old school teacher, Mini Miss. | 0:11:37 | 0:11:41 | |
CHEERING | 0:11:41 | 0:11:43 | |
-What have you been up to, Miss? -I helped Stephen Hawking | 0:11:44 | 0:11:47 | |
with his physics homework. He really isn't very good. | 0:11:47 | 0:11:50 | |
I should explain that I had an accident with my time machine, | 0:11:50 | 0:11:53 | |
and to cut a long story short, my 65-year-old science teacher | 0:11:53 | 0:11:57 | |
has come back as a ten-year-old. She's now the only teacher who can | 0:11:57 | 0:12:01 | |
-get away with travelling to school in Heelys. -Hurry up! | 0:12:01 | 0:12:04 | |
My quantum theories aren't going to write themselves! | 0:12:04 | 0:12:07 | |
Sorry, Miss. What's on the curriculum today? | 0:12:07 | 0:12:09 | |
-Today we're looking at centrifugal force. -Of course we are. I knew that. | 0:12:09 | 0:12:15 | |
Teams have to master the use of it in a game called Funnel Force. | 0:12:15 | 0:12:18 | |
You have to spin a ball in a funnel without stopping. | 0:12:18 | 0:12:22 | |
OK, that's looks tricky. | 0:12:23 | 0:12:25 | |
Whoever gets the most amount of balls in their cylinder | 0:12:25 | 0:12:28 | |
wins the game. | 0:12:28 | 0:12:29 | |
That's not that easy because each team has to do this whilst | 0:12:29 | 0:12:32 | |
racing around an obstacle course. | 0:12:32 | 0:12:34 | |
-I shall demonstrate, if that's OK with you, Miss. -OK, then. | 0:12:34 | 0:12:38 | |
I've brought my own, which I specially prepared. | 0:12:38 | 0:12:40 | |
-No, I know. I happen to be very good at this. -Richard. | 0:12:40 | 0:12:43 | |
I know, it's going so fast you can hardly see it move. | 0:12:43 | 0:12:46 | |
-You'd think it was stuck. -Richard! | 0:12:46 | 0:12:48 | |
I'll get on with it. This is what you do, teams. Pay attention. | 0:12:48 | 0:12:51 | |
Across the Bridge Of Destiny, | 0:12:51 | 0:12:53 | |
sticking to the left-hand side. This is difficult. | 0:12:53 | 0:12:55 | |
If the ball falls out and lands in the septic tank, leave it, | 0:12:55 | 0:12:59 | |
you don't want it back, trust me! That ball is out of play. | 0:12:59 | 0:13:02 | |
Then turn round onto the other side of the bridge, | 0:13:02 | 0:13:05 | |
dash back and the next team member goes. | 0:13:05 | 0:13:07 | |
If you get across the bridge successfully, you carry on, | 0:13:07 | 0:13:10 | |
down the stairs, here, and around to the high jump. | 0:13:10 | 0:13:13 | |
If the ball falls out at any point from hereon in, | 0:13:13 | 0:13:16 | |
stop exactly where you are. Freeze, don't move. | 0:13:16 | 0:13:19 | |
A Lab Rat will give you another ball to put in the funnel. | 0:13:19 | 0:13:22 | |
You can't move until it's spinning again. Once it's up and spinning, | 0:13:22 | 0:13:26 | |
you carry on. Past my reinvention of the bicycle. Do you like that? | 0:13:26 | 0:13:29 | |
It never worked. Across the Stepping Stones of Science. | 0:13:29 | 0:13:32 | |
Drop down to the end. Then the Yellow Team stop here. | 0:13:32 | 0:13:35 | |
Put their ball in that beacon. The Red Team in that one. | 0:13:35 | 0:13:38 | |
Then you return back across the bridge. When you get back to | 0:13:38 | 0:13:41 | |
your base, you high-five the next team member and they can set off. | 0:13:41 | 0:13:45 | |
-Does everybody understand the rules? -ALL: Yes! | 0:13:45 | 0:13:48 | |
We will be watching. If the ball comes out of the funnel, freeze, | 0:13:48 | 0:13:52 | |
a Lab Rat will give you another one. | 0:13:52 | 0:13:54 | |
You can't set off until it's spinning again. OK? | 0:13:54 | 0:13:57 | |
You have some time to do this | 0:13:57 | 0:13:59 | |
and that time starts...now! | 0:13:59 | 0:14:02 | |
CHEERING | 0:14:02 | 0:14:03 | |
Use the force. | 0:14:03 | 0:14:05 | |
Absolute concentration shown on | 0:14:05 | 0:14:07 | |
the faces of both competitors here today. | 0:14:07 | 0:14:10 | |
They're determined not to mess up. | 0:14:10 | 0:14:12 | |
Ah. Like that. The red ball is down and the yellow ball is down as well. | 0:14:12 | 0:14:18 | |
Straight away, problems on the Bridge Of Destiny. | 0:14:18 | 0:14:23 | |
Both of the balls ending up in the septic tank. | 0:14:23 | 0:14:26 | |
But they're back out there already, | 0:14:26 | 0:14:28 | |
making short work of the bridge this time. | 0:14:28 | 0:14:31 | |
Reds lose another ball, But as they're over the bridge, | 0:14:31 | 0:14:34 | |
one of my Lab Rats will get them going again | 0:14:34 | 0:14:36 | |
from where it was dropped. | 0:14:36 | 0:14:38 | |
A spill from the Yellows. | 0:14:41 | 0:14:42 | |
It's obviously not as easy as I made it look, | 0:14:42 | 0:14:45 | |
but then I'm a professional. And it's neck-and-neck as they | 0:14:45 | 0:14:49 | |
round the summertime clock corner and make their way | 0:14:49 | 0:14:52 | |
under the limbo pole. Good ball control there by both teams. | 0:14:52 | 0:14:55 | |
Reds have their first score, and almost simultaneously, | 0:14:56 | 0:14:59 | |
a big drop from the yellows. That could cost them. | 0:14:59 | 0:15:03 | |
She recovers well, | 0:15:03 | 0:15:04 | |
scores for the Yellows, and heads back to her waiting team-mates. | 0:15:04 | 0:15:09 | |
CHEERING | 0:15:09 | 0:15:13 | |
Some absolutely fabulous play from the Red Team right now. | 0:15:16 | 0:15:20 | |
Really, really controlled. Elena, I think, | 0:15:20 | 0:15:23 | |
has a particular skill for this. She has mastered the force. | 0:15:23 | 0:15:28 | |
She lost it just when I said that, that was my fault! | 0:15:30 | 0:15:33 | |
The Yellows look to have made up grand, here. Can they catch | 0:15:33 | 0:15:37 | |
the Reds, who looked to be running away with it up to this point? | 0:15:37 | 0:15:42 | |
There's a lot of centrifugal force going on around us all the time. | 0:15:47 | 0:15:50 | |
When a car turns left or right, | 0:15:50 | 0:15:52 | |
you'll feel it pushing you the other way. If you spin something | 0:15:52 | 0:15:56 | |
on the end of a piece of rope, that is centrifugal force. | 0:15:56 | 0:15:59 | |
The thing that's spinning wants to keep going on in a straight line, | 0:15:59 | 0:16:03 | |
but it can't because the rope is holding it back. This is the same. | 0:16:03 | 0:16:06 | |
The funnel is holding the ball in. It's centrifugal force that explains | 0:16:06 | 0:16:10 | |
why you can stay in a rollercoaster when it does loop the loop, | 0:16:10 | 0:16:14 | |
how they do the motorcycle wall of death, and why the clothes | 0:16:14 | 0:16:17 | |
stick to the outside of the drum in a washing machine. | 0:16:17 | 0:16:20 | |
'Five, four, three, two, one...' | 0:16:22 | 0:16:26 | |
And your time is up! | 0:16:27 | 0:16:30 | |
Some great play from both teams. That was very difficult, | 0:16:30 | 0:16:33 | |
mastering centrifugal force. Let's find out who has won. | 0:16:33 | 0:16:37 | |
Yellow Team, three. | 0:16:37 | 0:16:39 | |
Red team, I make that four for the Red Team. The Reds are the winners. | 0:16:39 | 0:16:43 | |
A score now of 3-1. Congratulations, all. | 0:16:45 | 0:16:49 | |
Centrifugal force doesn't just affect ping-pong balls, | 0:16:49 | 0:16:52 | |
motorcycle riders and clothes in the washing machine. | 0:16:52 | 0:16:55 | |
It can affect anything, even the air. | 0:16:55 | 0:16:57 | |
But what about...fire? | 0:16:57 | 0:16:59 | |
When man discovered fire, it changed his world, forever. | 0:17:01 | 0:17:07 | |
That discovery was made millennia ago. | 0:17:10 | 0:17:13 | |
This Lab Rat, on the other hand, is still trying... | 0:17:13 | 0:17:16 | |
and still trying. | 0:17:16 | 0:17:19 | |
As I would never let him actually handle a naked flame, | 0:17:19 | 0:17:22 | |
his lack of success is no bad thing. | 0:17:22 | 0:17:26 | |
But what's this? | 0:17:26 | 0:17:27 | |
Matches? No, Lab Rat, no! | 0:17:27 | 0:17:31 | |
No-one, especially a stupid Lab Rat, should play with matches. | 0:17:31 | 0:17:36 | |
Ever! If you do, you could get burnt, | 0:17:36 | 0:17:40 | |
or in this Lab Rat's case... very wet. | 0:17:40 | 0:17:44 | |
This one, however, is highly trained and very responsible. | 0:17:44 | 0:17:49 | |
Well, for a Lab Rat, anyway. | 0:17:49 | 0:17:51 | |
He's going to try and create a tornado of fire. | 0:17:51 | 0:17:54 | |
In order to produce a fire tornado, | 0:17:56 | 0:17:58 | |
all we need is to create spinning air around a burning fire. | 0:17:58 | 0:18:02 | |
As the fire rises it will be drawn into the spiralling air, | 0:18:02 | 0:18:06 | |
creating a tall, spinning column of fire. | 0:18:06 | 0:18:09 | |
So to make our own fire tornado, | 0:18:09 | 0:18:11 | |
I've asked the Lab Rat to light a fire on this revolving plate. | 0:18:11 | 0:18:15 | |
But will it work, or will centrifugal force | 0:18:15 | 0:18:18 | |
fling the fire out of control? | 0:18:18 | 0:18:20 | |
I'll stop the tape there because I want to ask, will it work? Teams? | 0:18:20 | 0:18:23 | |
What do you reckon? Will this work? | 0:18:23 | 0:18:25 | |
Will it have an effect? Yellow Team? | 0:18:25 | 0:18:29 | |
-I think it will cave in. -You think it will cave in? OK. | 0:18:29 | 0:18:33 | |
-Red team, any theories? -There's going to be a fire tornado. | 0:18:33 | 0:18:36 | |
-You think there'll be a fire tornado? -Yeah. -There was a hand | 0:18:36 | 0:18:39 | |
going up over there. This is my special mug-tree microphone. | 0:18:39 | 0:18:43 | |
You can hang mugs on it, and it's a microphone. You're impressed! | 0:18:43 | 0:18:47 | |
-Yeah. -You're not impressed, are you? -I am. -What do you think? | 0:18:47 | 0:18:51 | |
I think it's just going to stay in the same place, but turn around, | 0:18:51 | 0:18:54 | |
-so it looks like a tornado but actually it's not. -Right. | 0:18:54 | 0:18:58 | |
So do we reckon we'll see a lot happening or only a bit happening? | 0:18:58 | 0:19:02 | |
You think a lot? | 0:19:02 | 0:19:04 | |
Not very much would happen, because... | 0:19:04 | 0:19:08 | |
Well, it might happen, but it's not going to be | 0:19:08 | 0:19:11 | |
-very powerful, if you like. -So only a bit. So let's get an idea again. | 0:19:11 | 0:19:15 | |
Red Team, what to you think will happen when we spin the fire? | 0:19:15 | 0:19:19 | |
-A fire tornado. -I think it will look like stream line going up. | 0:19:19 | 0:19:24 | |
-Right. Yellow Team, what do you think? -I think the fire, | 0:19:24 | 0:19:27 | |
the wheel will go round, but the fire's up, so it's not doing much. | 0:19:27 | 0:19:33 | |
You don't think we'll see anything. You think we'll see a fire tornado. | 0:19:33 | 0:19:36 | |
There's a point here. If this happens, if there is a tornado, | 0:19:36 | 0:19:39 | |
if nothing happens, if you're right, you get a point. | 0:19:39 | 0:19:42 | |
Let's see what happens. | 0:19:42 | 0:19:43 | |
OK, here it goes. Round and round. | 0:19:44 | 0:19:48 | |
And round...and round. | 0:19:48 | 0:19:52 | |
Not very much happening there. | 0:19:52 | 0:19:54 | |
It looks like it has not created a fire tornado. | 0:19:54 | 0:19:59 | |
I don't know, having seen that. It looked borderline to me. | 0:20:01 | 0:20:04 | |
Do we think it had an effect of or not? | 0:20:04 | 0:20:08 | |
You could see a bit. It wasn't really...not a tornado. | 0:20:08 | 0:20:11 | |
I've taken an executive decision at the lowest possible level. | 0:20:11 | 0:20:15 | |
It's my lab. I'll give you each a point, a point for both teams. | 0:20:15 | 0:20:18 | |
It's time for us to move on to a messy, messy, mess test. | 0:20:21 | 0:20:24 | |
That means both teams have to go off and get changed. | 0:20:24 | 0:20:27 | |
Get changed into your protective suits, please, guys. | 0:20:27 | 0:20:31 | |
There is a way we can affect the fire with centrifugal force. | 0:20:31 | 0:20:35 | |
Because the air around it is being affected by centrifugal force. | 0:20:35 | 0:20:38 | |
And if we can put something in the way of that air to make it spin, | 0:20:38 | 0:20:42 | |
theoretically we could actually make a fire tornado. | 0:20:42 | 0:20:46 | |
Right, here we go. | 0:20:48 | 0:20:50 | |
Straight away, the air is pushed out by the wire grid in the way. | 0:20:50 | 0:20:55 | |
So the air is spinning, and spinning | 0:20:55 | 0:20:58 | |
and look, this is making the fire spin, too. | 0:20:58 | 0:21:01 | |
And yes, it's producing a fire tornado. | 0:21:01 | 0:21:03 | |
Perfect for roasting your marshmallows. | 0:21:03 | 0:21:07 | |
I'd say that was a fire tornado, personally. | 0:21:09 | 0:21:12 | |
APPLAUSE | 0:21:12 | 0:21:14 | |
It wasn't huge. But it worked. Right, it's time for us to move on | 0:21:14 | 0:21:17 | |
to the messy, messy, mess test. | 0:21:17 | 0:21:19 | |
Which today is in the septic tank. Are you comfortable in there guys? | 0:21:23 | 0:21:28 | |
-Yes. -Good. Ooh, this morning the waterworks started to overflow, | 0:21:28 | 0:21:31 | |
so I offered to store some of the excess in here. | 0:21:31 | 0:21:34 | |
Interestingly, I found something moving in there earlier on. | 0:21:34 | 0:21:37 | |
I hit it with a spade, so I think it's dead now. | 0:21:37 | 0:21:41 | |
If you do see anything, give me a yell. I still have the spade handy. | 0:21:41 | 0:21:44 | |
This is the game. Hidden in the tank are discs. | 0:21:44 | 0:21:47 | |
Some are like this one. Duds. | 0:21:47 | 0:21:49 | |
But the ones you're after, are like these, my Lab Rat is holding up. | 0:21:49 | 0:21:53 | |
They feature your team's colour and the name of a prize. | 0:21:53 | 0:21:56 | |
Things like snotty slime clock. A set of robo-bugs, | 0:21:56 | 0:21:59 | |
a radio-controlled airship. Lab Rat, if you'd hide those, please. | 0:21:59 | 0:22:02 | |
Well, that will teach you to play with matches. | 0:22:02 | 0:22:05 | |
And then get out of the septic tank. Now your job, teams, is to get | 0:22:05 | 0:22:08 | |
as many of the prize discs as you can into the basket. You've got one | 0:22:08 | 0:22:12 | |
for red over there. One for the yellow team here. | 0:22:12 | 0:22:14 | |
The team to get the most prize discs into their basket will take home | 0:22:14 | 0:22:18 | |
the prizes written on them. | 0:22:18 | 0:22:20 | |
The losing team has to blow their prizes up. | 0:22:20 | 0:22:23 | |
Red, you'll be starting first because you've got the most points. | 0:22:23 | 0:22:26 | |
They've earned you a five second advantage. | 0:22:26 | 0:22:29 | |
When you hear the first siren, you start. | 0:22:29 | 0:22:31 | |
Yellow team, you can only begin when you hear the second siren. | 0:22:31 | 0:22:35 | |
You have got some time to get as many prize discs | 0:22:35 | 0:22:37 | |
into the basket as possible and that some time starts now! | 0:22:37 | 0:22:43 | |
The Yellows remain frozen like statues | 0:22:43 | 0:22:46 | |
as the Reds set to work around them. | 0:22:46 | 0:22:49 | |
SIREN | 0:22:49 | 0:22:50 | |
There's the second siren. The Yellows should be off, | 0:22:50 | 0:22:53 | |
but they're still doing their statue impressions! | 0:22:53 | 0:22:56 | |
And what's this? More confusion in the ranks with the Red Team | 0:22:59 | 0:23:02 | |
unsure whether the yellow prize disc in his hand | 0:23:02 | 0:23:05 | |
is actually a red disc in disguise. | 0:23:05 | 0:23:08 | |
Luckily a member of the Red Team has pointed out that the disc is yellow, | 0:23:08 | 0:23:12 | |
so it's probably a yellow disc. Nice one! | 0:23:12 | 0:23:15 | |
They're all at it, the Yellow member, there, | 0:23:17 | 0:23:19 | |
seeing a red disc and taking it for his own. | 0:23:19 | 0:23:22 | |
That siren means, I don't know how to put this, | 0:23:23 | 0:23:26 | |
there's more stuff on its way. On the bad side, that means | 0:23:26 | 0:23:29 | |
there's more of whatever's in there about to join them. | 0:23:29 | 0:23:32 | |
On the plus side, there might be more prize discs. | 0:23:32 | 0:23:35 | |
A yellow disc in a yellow basket. | 0:23:38 | 0:23:41 | |
We're off the mark now, at last. Another siren, and another member | 0:23:41 | 0:23:44 | |
of the Yellow Team completely covered in disgusting, smelly, | 0:23:44 | 0:23:48 | |
well, we don't know what the brown stuff is. | 0:23:48 | 0:23:51 | |
Safe to say I wouldn't put it on my cereal in the morning! | 0:23:51 | 0:23:55 | |
Hurry, teams, there's only a random amount of some time left | 0:24:09 | 0:24:13 | |
on the clock, so maybe there's no some time to spare. | 0:24:13 | 0:24:17 | |
Everyone putting in a supreme amount of effort here today, but it | 0:24:22 | 0:24:26 | |
looks like the Yellows are turning that hard work into results. | 0:24:26 | 0:24:30 | |
'Five, four, three, two, one.' | 0:24:30 | 0:24:35 | |
SIRENS | 0:24:36 | 0:24:39 | |
OK! Both teams! You look...nice in there. | 0:24:39 | 0:24:43 | |
Time is up. | 0:24:43 | 0:24:44 | |
My Lab Rats are counting up the discs to see which team has won. | 0:24:44 | 0:24:50 | |
One, two, three, four, five. Well done. Five for the Reds. | 0:24:50 | 0:24:53 | |
For the Yellows, we have, one, two, three, four, five... | 0:24:53 | 0:24:57 | |
Six for the yellows! You're the winner! | 0:24:57 | 0:25:00 | |
CHEERING AND APPLAUSE | 0:25:00 | 0:25:03 | |
Yellow Team, you are the winners, so you'll each be taking home | 0:25:03 | 0:25:06 | |
one of the following. What have we got, Lab Rat? | 0:25:06 | 0:25:09 | |
Thank you, Ninja Nan for modelling these for us. Planetarium, each. | 0:25:09 | 0:25:12 | |
-3D globe puzzle. -CHEERING | 0:25:13 | 0:25:16 | |
-A Hulk Smash-Hands. -CHEERING | 0:25:16 | 0:25:18 | |
-A snotty slime clock. -CHEERING | 0:25:18 | 0:25:20 | |
-A transforming robot. -CHEERING | 0:25:20 | 0:25:23 | |
And a robo-spider. | 0:25:23 | 0:25:25 | |
Each of you will be taking those prizes home. | 0:25:25 | 0:25:28 | |
CHEERING AND APPLAUSE | 0:25:28 | 0:25:30 | |
Now the slightly less cheery bit, that I really enjoy, | 0:25:30 | 0:25:34 | |
because we'll find out, Reds, these are the prizes you would have won. | 0:25:34 | 0:25:38 | |
You would each have taken home a 3D globe puzzle. | 0:25:38 | 0:25:41 | |
AUDIENCE: Aw! | 0:25:41 | 0:25:43 | |
Hulk Smash-Hands. | 0:25:43 | 0:25:44 | |
AUDIENCE: Aw! | 0:25:44 | 0:25:45 | |
A turbo blimp. | 0:25:45 | 0:25:47 | |
AUDIENCE: Aw! | 0:25:47 | 0:25:48 | |
A transforming robot. | 0:25:48 | 0:25:49 | |
AUDIENCE: Aw! | 0:25:49 | 0:25:51 | |
Robo-bugs. | 0:25:51 | 0:25:52 | |
AUDIENCE: Aw! | 0:25:52 | 0:25:53 | |
But you're not taking those home with you. Instead, Reds, | 0:25:53 | 0:25:56 | |
you're going to blow your prizes up. Time for Bidet Goes Bang. | 0:25:56 | 0:26:01 | |
So this is it. Reds, how you feeling right now? | 0:26:09 | 0:26:12 | |
-Sad, but happy at the same time. -I think you took it very well when | 0:26:12 | 0:26:16 | |
I told you you had to blow your prizes up. | 0:26:16 | 0:26:18 | |
-Who's going to push the plunger? -We're all going to do it. | 0:26:18 | 0:26:21 | |
-Altogether? -Yeah. -What went wrong in the game? Why did you lose? | 0:26:21 | 0:26:25 | |
I think we didn't use team work, we just went for it. | 0:26:25 | 0:26:28 | |
You're now going to blow your prizes up. No putting it off. | 0:26:28 | 0:26:31 | |
Your prizes are in the bidet, ready to go bang. The Yellows are here, | 0:26:31 | 0:26:36 | |
very pleased with themselves and with a mountain of prizes. | 0:26:36 | 0:26:39 | |
Reds, this is it, the moment of truth. | 0:26:39 | 0:26:41 | |
Lift the plunger and be ready. We'll give you a countdown. Lift it up. | 0:26:41 | 0:26:45 | |
-Ready? -Five, four, three, two, one. Go! | 0:26:45 | 0:26:49 | |
BANG AND SMASHING | 0:26:49 | 0:26:52 | |
That is all we've got time for today. We've learned all about | 0:26:54 | 0:26:57 | |
tornadoes and circular motion. Although with my idiot Lab Rats | 0:26:57 | 0:27:01 | |
around the place I usually feel like I'm going round in circles anyway. | 0:27:01 | 0:27:04 | |
See you next time. | 0:27:04 | 0:27:06 | |
Blast Lab was recorded before a live studio audience. | 0:27:15 | 0:27:18 | |
No Lab Rat was harmed during the filming. | 0:27:18 | 0:27:21 | |
That's what I told their mums, anyway! | 0:27:21 | 0:27:23 | |
