Right, I'm turning the machine up. | 0:00:34 | 0:00:37 | |
Turning it up. Turning it up a bit more now. You'll be fine. | 0:00:37 | 0:00:41 | |
Turning it up. Ooh. Arh. Yeah. | 0:00:41 | 0:00:43 | |
Sorry. OK. Just experimenting with a lab rat, there. | 0:00:43 | 0:00:50 | |
He'll be fine. Cross, but fine. | 0:00:50 | 0:00:53 | |
Hello. I'm Richard Hammond. Welcome to my Blast Lab! | 0:00:53 | 0:00:57 | |
APPLAUSE | 0:00:57 | 0:00:59 | |
This is the science show for people who think science is boring. | 0:00:59 | 0:01:04 | |
In a moment, we'll meet two teams of budding young scientists | 0:01:04 | 0:01:09 | |
who'll compete in cutting-edge scientific experiments. | 0:01:09 | 0:01:13 | |
The winning team will be win prizes. So will the losing team, | 0:01:13 | 0:01:17 | |
but unfortunately, they have to blow theirs up in an exploding bidet. | 0:01:17 | 0:01:22 | |
Let's see what's in store today... | 0:01:22 | 0:01:25 | |
Now, obviously, with this being a super secret underground lab, | 0:01:36 | 0:01:41 | |
I only use the very best to guard it. | 0:01:41 | 0:01:45 | |
A crack SAS team. | 0:01:45 | 0:01:47 | |
Funny thing though, they turned up to work this morning | 0:01:47 | 0:01:50 | |
and they were all wearing the same thing - green camouflage. | 0:01:50 | 0:01:55 | |
Embarrassing, so they've gone to get changed, | 0:01:55 | 0:01:58 | |
but I have a replacement - a one-woman fighting machine. | 0:01:58 | 0:02:02 | |
A woman who can fight a man with one finger in slippers and a hairnet. | 0:02:02 | 0:02:07 | |
Her, not the man, obviously. She is my Ninja Nan! | 0:02:07 | 0:02:11 | |
APPLAUSE | 0:02:11 | 0:02:14 | |
Ninja Nan. | 0:02:19 | 0:02:20 | |
Thanks for standing in. | 0:02:20 | 0:02:23 | |
I know she may look fragile, but she is in fact a fully trained ninja. | 0:02:23 | 0:02:28 | |
Yeah. There you go. Nan, take your place in security. | 0:02:31 | 0:02:36 | |
Oh, her batteries have gone again. Nan! Thank you. | 0:02:36 | 0:02:39 | |
If you'd like to take your place in security and look after things. | 0:02:39 | 0:02:44 | |
There she goes. Look at her move. | 0:02:44 | 0:02:47 | |
Look at the speed. Ninja Nan, are you settled in yet? | 0:02:47 | 0:02:51 | |
Oh, there she goes, look. | 0:02:51 | 0:02:52 | |
Yes. With her little ninja shopping trolley behind her. | 0:02:52 | 0:02:56 | |
Getting settled in. Oh, what's she after? It'll be her food for later. | 0:02:56 | 0:03:01 | |
Oh, yes, that's a rock cake, but being a ninja, it's real rock. | 0:03:01 | 0:03:06 | |
Only Ninja Nan can cope with that. | 0:03:06 | 0:03:09 | |
Right. Let's meet the people who are trying to get into my lab today. | 0:03:09 | 0:03:14 | |
Now, let's not get all giddy. They say they're the Yellow Team. | 0:03:17 | 0:03:22 | |
They've got the right lab coats on, but they could be anybody. | 0:03:22 | 0:03:26 | |
We have to be careful of security. This lab is top secret. | 0:03:26 | 0:03:31 | |
-Identify yourselves by name, please. -Megan. -Shekeera. -Alex. | 0:03:31 | 0:03:35 | |
Megan, Shekeera, Alex. Yes. That checks out with what I've got. | 0:03:35 | 0:03:39 | |
What hidden talent will you demonstrate to prove who you are? | 0:03:39 | 0:03:44 | |
This is Alex who's going to do baton twirling, it says here. | 0:03:44 | 0:03:48 | |
It's a baton and it's twirling. What do we reckon? | 0:03:48 | 0:03:51 | |
Yeah? All right. OK. That's it. You are the Yellow Team. | 0:03:51 | 0:03:56 | |
Come through. You're cleared through security. | 0:03:56 | 0:03:59 | |
APPLAUSE | 0:03:59 | 0:04:02 | |
That confirms then that you are our Yellow Team. | 0:04:03 | 0:04:06 | |
-Welcome. Where have you come from? -Norwich, and we're Team Sam. | 0:04:06 | 0:04:12 | |
That's your own name. You didn't need that. Yellow Team, welcome. | 0:04:12 | 0:04:16 | |
We're gonna meet the people who claim to be your opponents. | 0:04:16 | 0:04:21 | |
APPLAUSE | 0:04:21 | 0:04:23 | |
You've got the right lab coats. You say you're the Red Team. | 0:04:25 | 0:04:29 | |
-Prove it. Identify yourselves by name, please. -Stan. -Louis. -Dan! | 0:04:29 | 0:04:34 | |
Wow. Stan, Louis and Dan. That's right. Hidden talent... | 0:04:34 | 0:04:39 | |
It's Louis. What will you do to prove... What are you doing? | 0:04:39 | 0:04:43 | |
HE MOUTHS SILENTLY | 0:04:43 | 0:04:44 | |
-What are you doing? Speak up. -Miming. -Can't be a mime, you spoke. | 0:04:44 | 0:04:49 | |
It does say miming here and that is miming. Come through security. | 0:04:49 | 0:04:54 | |
You're clear past Ninja Nan. | 0:04:54 | 0:04:57 | |
Are we not too well today, Dan? Have you brought germs into my Blast Lab? | 0:04:59 | 0:05:04 | |
If you get any in that tank behind you, | 0:05:04 | 0:05:07 | |
overnight they mutate and they come out this big, with pincers. | 0:05:07 | 0:05:11 | |
Don't cough near there. Red Team. Welcome. Where have you come from? | 0:05:11 | 0:05:16 | |
Cornwall. And we're the Randomers. | 0:05:16 | 0:05:19 | |
Good name but useless. The Red Team will do for today. | 0:05:19 | 0:05:23 | |
Both teams, get ready for round one. | 0:05:23 | 0:05:26 | |
Go over there and get settled in. | 0:05:26 | 0:05:28 | |
I love cars and science, and here's something that's a bit of both. | 0:05:28 | 0:05:33 | |
He's a smooth ride with a sharp mind. My best friend, Oliver. | 0:05:33 | 0:05:37 | |
Oliver is fitted with the very latest hi-tech facts nav. | 0:05:53 | 0:05:58 | |
I should know because I fitted it. | 0:05:58 | 0:06:00 | |
As a result, it doesn't always work. | 0:06:00 | 0:06:03 | |
Some of its facts are wrong, some are right. | 0:06:03 | 0:06:07 | |
I want my teams to tell me which is which first. | 0:06:07 | 0:06:10 | |
Oliver will confirm it. If it's true, he'll do this... | 0:06:10 | 0:06:14 | |
SIREN BLARES AND HORN BEEPS | 0:06:14 | 0:06:16 | |
And he'll let us know if it's false by doing this... | 0:06:16 | 0:06:19 | |
FOGHORN BLARES | 0:06:19 | 0:06:21 | |
Couldn't be simpler rules. Are we happy? | 0:06:21 | 0:06:24 | |
This is your first chance to earn points. Ready for a science fact? | 0:06:24 | 0:06:28 | |
Red Team, your first chance to earn a point. | 0:06:28 | 0:06:32 | |
I'm trying to make you nervous. Is it working? No. You look relaxed. | 0:06:32 | 0:06:37 | |
-I'm a bit nervous. -You are? -No. 'Course not. -OK. Here's your fact... | 0:06:37 | 0:06:41 | |
Lightning strikes somewhere on Earth ten times per minute. | 0:06:41 | 0:06:47 | |
Is that true or false? Have a chat. | 0:06:47 | 0:06:49 | |
You never know what one of you might know. I'll ask the audience. | 0:06:49 | 0:06:53 | |
Lightning strikes somewhere ten times a minute. True or false? | 0:06:53 | 0:06:56 | |
What do we think? | 0:06:56 | 0:06:57 | |
AUDIENCE SHOUT | 0:06:57 | 0:06:59 | |
Some true. Some false. Bit of a mix there. | 0:07:02 | 0:07:04 | |
Bit of a mix over here as well. | 0:07:04 | 0:07:06 | |
OK. Reds, have we come to a conclusion? | 0:07:06 | 0:07:09 | |
If you can all agree on an answer. | 0:07:09 | 0:07:11 | |
-False. -Louis, are you going to be spokesperson? -False. -False. | 0:07:11 | 0:07:16 | |
Oliver, is it true or false? | 0:07:16 | 0:07:18 | |
FOGHORN BLARES | 0:07:18 | 0:07:20 | |
It's false. Well done. That's a point for you. | 0:07:20 | 0:07:22 | |
CHEERING | 0:07:22 | 0:07:24 | |
It actually strikes - I've got the figures here - | 0:07:24 | 0:07:27 | |
6,000 times per minute, which is 100 times a second, which equates to | 0:07:27 | 0:07:32 | |
8,640,000 times a day. | 0:07:32 | 0:07:34 | |
Right. Yellow Team, here is your science fact. | 0:07:34 | 0:07:36 | |
Tell me whether this is true or false. | 0:07:36 | 0:07:39 | |
Have a think about it before you give your answer. | 0:07:39 | 0:07:41 | |
The average pencil lead can draw a line | 0:07:41 | 0:07:44 | |
over 200 metres long before it runs out. | 0:07:44 | 0:07:49 | |
Have a talk. Have a think. Have a think. Don't let me rush you. | 0:07:49 | 0:07:53 | |
-Audience, true or false? -AUDIENCE SHOUTS | 0:07:53 | 0:07:57 | |
Mostly true there, I think, | 0:07:58 | 0:08:00 | |
but don't go too much by what the audience think. | 0:08:00 | 0:08:02 | |
-What do you think? -False. -False. Oliver, is it true or false? | 0:08:02 | 0:08:06 | |
FOGHORN BLARES | 0:08:06 | 0:08:08 | |
-It's false. -CHEERING | 0:08:08 | 0:08:10 | |
There you go. | 0:08:10 | 0:08:12 | |
The longest pencil in the world was created by Faber-Castell in 2002. | 0:08:12 | 0:08:15 | |
It was 19.75 metres long. | 0:08:15 | 0:08:18 | |
80 centimetres in dia... You're not interested in this, are you? | 0:08:18 | 0:08:21 | |
The average pencil lead could draw a line about 35 miles long. | 0:08:21 | 0:08:26 | |
What do you think about that? So that's how false that was. | 0:08:26 | 0:08:29 | |
Or 45,000 words, if you wanted to wear one out. | 0:08:29 | 0:08:33 | |
-Shall I just ask you the questions? -Yeah. -OK. | 0:08:33 | 0:08:36 | |
Here is your third question. This works differently - | 0:08:36 | 0:08:39 | |
it isn't true or false. This is one I need you to answer. | 0:08:39 | 0:08:42 | |
Write it on the boards in front of you. | 0:08:42 | 0:08:44 | |
How many moons does the planet Uranus have? | 0:08:44 | 0:08:48 | |
How many moons does Uranus have? Think while I talk to the audience. | 0:08:48 | 0:08:52 | |
Anybody know the answer to that, or would want to hazard a guess? | 0:08:52 | 0:08:55 | |
I can come and ask you by using my new invention, boot-mike. | 0:08:55 | 0:09:00 | |
-Talk into it. It's a microphone. -Nine. | 0:09:00 | 0:09:03 | |
-Nine. -17. | 0:09:03 | 0:09:05 | |
17. Just talk to the boot. | 0:09:05 | 0:09:06 | |
Any astronomers? Anybody actually look at things through telescopes? | 0:09:06 | 0:09:10 | |
-Do you? -Yeah. 20. | 0:09:10 | 0:09:11 | |
-20. OK. We're getting a real ballpark figure here. Yes. -Three. | 0:09:11 | 0:09:15 | |
Three. That's quite a range established by a young man here. | 0:09:15 | 0:09:18 | |
OK. Audience, I'll take some from here, finally. Yeah. | 0:09:18 | 0:09:22 | |
-72. -Woah! Now we've got three to 72. | 0:09:22 | 0:09:24 | |
-This is more like it. -12? -OK. | 0:09:24 | 0:09:26 | |
We've got three to 72 and just about all the numbers in-between. | 0:09:26 | 0:09:30 | |
All facts gathered in with the use of my handy boot-mike, | 0:09:30 | 0:09:34 | |
which is not impressing anybody in the Blast Lab today. | 0:09:34 | 0:09:38 | |
You've both written down answers. | 0:09:38 | 0:09:40 | |
Let's have a look at what you've got. Turn your boards round, please. | 0:09:40 | 0:09:44 | |
For the Red Team... | 0:09:44 | 0:09:45 | |
For the yellow team... That's quite spooky. | 0:09:45 | 0:09:48 | |
You conducting your own experiment and doing ESP in my Blast Lab? | 0:09:48 | 0:09:52 | |
That's quite a coincidence. Right. Here's the real answer. It is... | 0:09:52 | 0:09:56 | |
27...that we know of. Scientists think there may be more. | 0:09:56 | 0:09:59 | |
As you've both got the same answer, | 0:09:59 | 0:10:01 | |
you're both furthest and closest to the real answer, | 0:10:01 | 0:10:04 | |
but I'm feeling generous. | 0:10:04 | 0:10:06 | |
I'll give both teams a point. | 0:10:06 | 0:10:08 | |
CHEERING | 0:10:08 | 0:10:10 | |
CHEERING AND APPLAUSE | 0:10:19 | 0:10:21 | |
That is all to come, but right now, it's time for Mini Science, | 0:10:23 | 0:10:26 | |
where our teams get to use household objects | 0:10:26 | 0:10:29 | |
to conduct extraordinary science experiments. | 0:10:29 | 0:10:32 | |
Now, my old school science teacher | 0:10:32 | 0:10:35 | |
accidentally ended up as a ten-year-old | 0:10:35 | 0:10:38 | |
during an experiment with time travel. Yes. | 0:10:38 | 0:10:41 | |
She's teaching at the local school, | 0:10:41 | 0:10:43 | |
but she is the only teacher ever to get a detention | 0:10:43 | 0:10:45 | |
after one of her own colleagues mistook her for one of her class. | 0:10:45 | 0:10:49 | |
So she's not in a very good mood with me. And it is Mini Miss. | 0:10:49 | 0:10:52 | |
CHEERING | 0:10:52 | 0:10:55 | |
-Hello, Miss. -Hello, Richard. | 0:10:58 | 0:11:00 | |
Hello. What are we doing today? | 0:11:00 | 0:11:02 | |
-We're going to be looking at air particles. -Brilliant. | 0:11:02 | 0:11:05 | |
But Miss, air particles are tiny. | 0:11:05 | 0:11:07 | |
There's billions of them, and we can't... | 0:11:07 | 0:11:10 | |
I can't see that one. I can't... | 0:11:10 | 0:11:11 | |
I can't see them anywhere. | 0:11:11 | 0:11:13 | |
-How can we look at them? -Cos we're not looking at the particles. | 0:11:13 | 0:11:16 | |
We look at the effect it has on everything else. | 0:11:16 | 0:11:19 | |
Well, we're going to be looking at them in a game called Ping Pong Pass. | 0:11:19 | 0:11:23 | |
The aim of the game is to get the most amount of balls | 0:11:23 | 0:11:26 | |
from these buckets to the cylinders | 0:11:26 | 0:11:28 | |
using the flow of air from the hairdryers. | 0:11:28 | 0:11:31 | |
Each team member stands in a zone, | 0:11:31 | 0:11:33 | |
and the ball should be passed from one to the other, | 0:11:33 | 0:11:36 | |
using the hairdryers. | 0:11:36 | 0:11:38 | |
OK. So they can't use their hands for this, then? | 0:11:38 | 0:11:42 | |
-No. Well, they have to hold the hairdryers. -Yes, Miss. | 0:11:42 | 0:11:44 | |
So they have to hold the hairdryer, but they can't touch the ball. | 0:11:44 | 0:11:48 | |
That must move in the flow from one to another. | 0:11:48 | 0:11:50 | |
All right, teams, so you know what you've got to do. Sounds tricky. | 0:11:50 | 0:11:55 | |
Let's find out if it is. | 0:11:55 | 0:11:56 | |
You've got some time to do this, and that some time starts... | 0:11:56 | 0:12:01 | |
..just then. | 0:12:02 | 0:12:03 | |
CHEERING AND APPLAUSE | 0:12:03 | 0:12:05 | |
AUDIENCE SHOUT | 0:12:10 | 0:12:12 | |
It is air particles making this possible. | 0:12:18 | 0:12:20 | |
I can demonstrate with my hairdryer here. | 0:12:20 | 0:12:22 | |
Now, if I set it going, | 0:12:22 | 0:12:24 | |
the ball isn't balancing... | 0:12:24 | 0:12:27 | |
on top of the column of air. | 0:12:27 | 0:12:28 | |
It's actually held within it, | 0:12:28 | 0:12:30 | |
and I can demonstrate | 0:12:30 | 0:12:31 | |
by putting smoke through it. | 0:12:31 | 0:12:33 | |
If you put the smoke in, | 0:12:33 | 0:12:34 | |
you can see the fast-moving stream of smoke | 0:12:34 | 0:12:37 | |
in the middle. | 0:12:37 | 0:12:38 | |
All the particles there | 0:12:38 | 0:12:39 | |
are getting spaced out further apart. | 0:12:39 | 0:12:41 | |
The air around the outside | 0:12:41 | 0:12:43 | |
that you can see in the smoke there, | 0:12:43 | 0:12:45 | |
is where these air particles | 0:12:45 | 0:12:46 | |
are rushing to replace them, | 0:12:46 | 0:12:48 | |
and they're holding the ball in place. | 0:12:48 | 0:12:50 | |
And this effect is why you can tilt it. Look! | 0:12:50 | 0:12:53 | |
It's not balancing, | 0:12:53 | 0:12:54 | |
it's being held in place by air pressure, | 0:12:54 | 0:12:57 | |
by particles moving in. | 0:12:57 | 0:12:58 | |
Fire fighters use air particles, if you like - | 0:12:58 | 0:13:01 | |
when there's a fire in the room, they use a fan | 0:13:01 | 0:13:04 | |
to push a load more air into the room | 0:13:04 | 0:13:06 | |
and all those particles | 0:13:06 | 0:13:07 | |
take up all the space | 0:13:07 | 0:13:09 | |
and they push the smoke out of the room. | 0:13:09 | 0:13:11 | |
Clever things, air particles. Let's see how they're doing. | 0:13:11 | 0:13:15 | |
Stan dunking one for the Reds. | 0:13:18 | 0:13:20 | |
Shekeera doing the same for the Yellows. | 0:13:20 | 0:13:23 | |
Oh, a dropped ball for the Reds. | 0:13:24 | 0:13:27 | |
Yellows going for a changeover. | 0:13:29 | 0:13:31 | |
Oh, no, not this time. | 0:13:31 | 0:13:32 | |
Stan, again scoring for the Reds. | 0:13:34 | 0:13:37 | |
And Shekeera... | 0:13:37 | 0:13:40 | |
likewise for the Yellows. | 0:13:40 | 0:13:42 | |
It is anybody's game at this point. | 0:13:42 | 0:13:44 | |
Oh, and Stan's missed one for the Reds. | 0:13:48 | 0:13:52 | |
OK. Teams, that is it. Time is up. Time is up. | 0:13:54 | 0:13:59 | |
Well, let's find out who's won. | 0:14:01 | 0:14:04 | |
Stan, did you get it in as he said, "One"? | 0:14:04 | 0:14:06 | |
That was the closest I've ever seen at the end of the game. | 0:14:06 | 0:14:09 | |
Five, four, three, two, one, it went in, so we'll allow that. | 0:14:09 | 0:14:13 | |
Right. Let's see which team has won. | 0:14:13 | 0:14:14 | |
Lab rats, count them up, please. Bear with us, audience. | 0:14:14 | 0:14:18 | |
They're operating at the absolute limit | 0:14:18 | 0:14:20 | |
of their capabilities right now, counting stuff. | 0:14:20 | 0:14:24 | |
OK. Lab rat, over here. | 0:14:24 | 0:14:26 | |
How many for the Reds? Six. Six for the Reds. | 0:14:26 | 0:14:29 | |
Let's see how the Yellows have done. | 0:14:29 | 0:14:31 | |
Lab rat, how many for the Yellows? Three. | 0:14:31 | 0:14:33 | |
The Reds have won. Well done! | 0:14:33 | 0:14:35 | |
That makes the score three-two to the Reds. Well done. | 0:14:35 | 0:14:39 | |
Another point for the Red Team. So, we've just seen fast moving air | 0:14:39 | 0:14:43 | |
holding something when the air's moving this way holds it there. | 0:14:43 | 0:14:47 | |
I wonder, if the air was faster and the object was larger, | 0:14:47 | 0:14:50 | |
could you use it to support an object this way? | 0:14:50 | 0:14:54 | |
I'm talking about flying. | 0:14:54 | 0:14:56 | |
Driving a go-kart can be a lot of fun. | 0:15:02 | 0:15:04 | |
Cruising around the track with the wind in your hair | 0:15:06 | 0:15:09 | |
and not a care in the world. | 0:15:09 | 0:15:10 | |
But imagine if you could fly above the track. | 0:15:10 | 0:15:16 | |
We've called in this paragliding expert, | 0:15:19 | 0:15:22 | |
or as he likes to be known, a wind commander. | 0:15:22 | 0:15:25 | |
Hello. I'm a wind commander. | 0:15:25 | 0:15:28 | |
He's brought his paraglider | 0:15:28 | 0:15:30 | |
to help turn our petrol-powered go-kart | 0:15:30 | 0:15:32 | |
into a magnificent wind-powered flying machine. | 0:15:32 | 0:15:36 | |
The paraglider works because as it's pulled along, | 0:15:38 | 0:15:41 | |
air rushes over and under its curved shape. | 0:15:41 | 0:15:44 | |
The theory goes that air flowing over the curve | 0:15:44 | 0:15:47 | |
becomes more spread out than air flowing under it. | 0:15:47 | 0:15:52 | |
The air that's less spread out pushes against the paraglider | 0:15:52 | 0:15:55 | |
and should lift it and the go-kart up. | 0:15:55 | 0:15:58 | |
However, if the air is not flowing fast enough, | 0:15:59 | 0:16:02 | |
this push won't be strong enough to lift the paraglider | 0:16:02 | 0:16:05 | |
and our go-kart will be as airborne as...an elephant. | 0:16:05 | 0:16:09 | |
He's going to attach his paraglider on to the go-kart | 0:16:16 | 0:16:19 | |
and attempt to use the thrust from the engine | 0:16:19 | 0:16:22 | |
combined with the upwards force of the paraglider | 0:16:22 | 0:16:25 | |
to make the go-kart fly through the air. | 0:16:25 | 0:16:27 | |
If he can pull this off, it'll be a world first. | 0:16:27 | 0:16:30 | |
Good luck, wind commander. | 0:16:32 | 0:16:35 | |
Hold the experiment because I think there's an extra point in this. | 0:16:35 | 0:16:39 | |
Score right now is three-two, but there's an extra point for the team | 0:16:39 | 0:16:43 | |
that can tell me correctly, will the go-kart fly or not? | 0:16:43 | 0:16:47 | |
What do we think? Have a chat amongst yourselves, both teams. | 0:16:47 | 0:16:50 | |
Going to ask you both for an answer. | 0:16:50 | 0:16:52 | |
Will it fly or not? Audience, any ideas? Will it fly or not? | 0:16:52 | 0:16:56 | |
Hang on. I tell you what, I'll get my microphone boot. | 0:16:56 | 0:17:00 | |
What do you reckon? | 0:17:00 | 0:17:02 | |
Depends what the CC of the engine is. | 0:17:02 | 0:17:04 | |
-So it depends on power. -It depends on power and it depends on weight. | 0:17:04 | 0:17:09 | |
If it's a lot of power and not much weight it will give you what? | 0:17:09 | 0:17:12 | |
-It will give you speed. -Yeah. | 0:17:12 | 0:17:15 | |
-And that might make a difference. -Yeah. | 0:17:15 | 0:17:17 | |
It depends if the bottom's covered or if there's holes in the bottom. | 0:17:17 | 0:17:21 | |
-Of the go-kart? -Yes. -The aerodynamics could affect it. | 0:17:21 | 0:17:26 | |
-Yeah. -The wind, as well. If there's like a wind against... | 0:17:26 | 0:17:29 | |
That's a point. Cos if we're trying to get fast-moving air | 0:17:29 | 0:17:33 | |
by driving that way, but the air's moving that way with us, | 0:17:33 | 0:17:36 | |
it'll cancel it out. | 0:17:36 | 0:17:37 | |
But if the air's moving that way, it's like going faster. | 0:17:37 | 0:17:40 | |
This is the clever corner. I've had enough of talking to you. | 0:17:40 | 0:17:44 | |
Right. That's good theories though, guys, really good theories. | 0:17:44 | 0:17:48 | |
Any other theories? Will it work or will it not? | 0:17:48 | 0:17:50 | |
I don't think it will because I don't think the up-thrust | 0:17:50 | 0:17:55 | |
will be strong enough to pull the go-kart and a person up because | 0:17:55 | 0:18:01 | |
gravity will prob...probably be... | 0:18:01 | 0:18:05 | |
stronger than the up-thrust. | 0:18:05 | 0:18:09 | |
So, the mass, the weight, of the go-kart and the rider, | 0:18:09 | 0:18:13 | |
they won't go enough lift... from that wind. | 0:18:13 | 0:18:16 | |
-OK. So you're thinking not. -No. -OK. | 0:18:16 | 0:18:19 | |
So the audience are pretty unanimous on this one. | 0:18:19 | 0:18:23 | |
Right. Teams, have you come up with your answers? | 0:18:23 | 0:18:26 | |
-So, Reds, your answer, what do you think? -Yes. | 0:18:26 | 0:18:30 | |
-You think it's going to work. -Yeah. | 0:18:30 | 0:18:33 | |
-OK. Yellows? -Yeah. -You think it's going to work, as well. | 0:18:33 | 0:18:37 | |
OK. Only one way to find out and settle this one. | 0:18:37 | 0:18:41 | |
Carry on with the experiment. | 0:18:41 | 0:18:43 | |
Here he goes. Let's see if he can make this baby fly. | 0:18:47 | 0:18:50 | |
The front wheels are off the ground but now they're back down again. | 0:18:52 | 0:18:56 | |
He nearly did it that time, but he's driven into the grass. Again. | 0:18:56 | 0:19:00 | |
Well, he's certainly not giving up easily, is he? | 0:19:04 | 0:19:07 | |
He seems to think he's flying, but I'm sure we can all agree he's not. | 0:19:11 | 0:19:17 | |
-It was four wheels, wasn't it? -No. | 0:19:18 | 0:19:21 | |
So there we go. Afraid no points for either team. It didn't work. | 0:19:21 | 0:19:25 | |
Should have known. Lab rats involved. | 0:19:25 | 0:19:28 | |
That's cough's not getting better, Dan. | 0:19:28 | 0:19:30 | |
Must be a lab rat can mend that for you. Right. | 0:19:30 | 0:19:33 | |
Both teams, you now have to go off | 0:19:33 | 0:19:34 | |
and get ready for Messy Messy Mess Test. | 0:19:34 | 0:19:37 | |
Believe me, you need your protective outfits. | 0:19:37 | 0:19:39 | |
So if you'd like to go away and get ready for that. | 0:19:39 | 0:19:42 | |
I just think it might be worth our while, audience, | 0:19:42 | 0:19:45 | |
while they're getting ready, finding out why it didn't work. | 0:19:45 | 0:19:49 | |
A go-kart is powered by its turning wheels, | 0:19:50 | 0:19:53 | |
rather than having a huge powerful fan at the back like a jet engine. | 0:19:53 | 0:19:58 | |
So in order to maintain its thrust, | 0:19:58 | 0:20:00 | |
its wheels need to stay on the track. | 0:20:00 | 0:20:03 | |
When it lifts off the ground, that thrust is lost and the rush of air | 0:20:03 | 0:20:07 | |
needed to make the paraglider work disappears. | 0:20:07 | 0:20:10 | |
Hang on, it looks like... yes, it looks like he's done it. | 0:20:11 | 0:20:15 | |
Oh, hold on a minute. No. He's just being carried off the track. | 0:20:15 | 0:20:19 | |
That was rubbish. Give us back that badge. | 0:20:20 | 0:20:22 | |
So, there you go. Right. It's time for us all | 0:20:26 | 0:20:28 | |
to move on to the Messy Messy Mess Test... | 0:20:28 | 0:20:30 | |
..which today is in the septic tank. | 0:20:33 | 0:20:37 | |
This is full of just mind-bogglingly awful stuff. | 0:20:37 | 0:20:41 | |
It's where all the waste from my experiments ends up. | 0:20:41 | 0:20:44 | |
So...comfortable in there? Don't worry, though. | 0:20:44 | 0:20:47 | |
One thing I can promise you, there's no creepy crawlies in there. | 0:20:47 | 0:20:51 | |
All the rats ate them. So, you'll be absolutely fine. | 0:20:51 | 0:20:55 | |
As well as rats in there, there are these. Discs. | 0:20:55 | 0:20:58 | |
Some are like this one. Duds. | 0:20:58 | 0:21:00 | |
But the ones you're after are these, as modelled by my lab rats. | 0:21:00 | 0:21:04 | |
They feature your team's colour and the names of prizes. | 0:21:04 | 0:21:08 | |
Now, there'll be things like multimedia MP3 player, | 0:21:08 | 0:21:11 | |
a wind-powered helicopter or a Blood, Bones And Body kit. | 0:21:11 | 0:21:14 | |
Our teams have to get as many of these discs from the septic tank | 0:21:14 | 0:21:17 | |
full of just the worst stuff you can imagine in to the baskets. | 0:21:17 | 0:21:21 | |
We've got one for the Yellow Team, one for the Red Team. | 0:21:21 | 0:21:24 | |
The winning team is the one to get the most prize discs | 0:21:24 | 0:21:28 | |
out of there and in to there. | 0:21:28 | 0:21:29 | |
And they will get to take home all the prizes written on the discs. | 0:21:29 | 0:21:33 | |
The losing team doesn't take the prizes home. | 0:21:33 | 0:21:37 | |
They have to blow them up in a bidet. | 0:21:37 | 0:21:39 | |
OK. You have some time to get as many discs from the septic tank | 0:21:39 | 0:21:43 | |
to the baskets as possible. | 0:21:43 | 0:21:44 | |
Red Team, you're ahead on points. | 0:21:44 | 0:21:47 | |
Those have bought you a five-second advantage, | 0:21:47 | 0:21:49 | |
so when you hear the first siren, Red, you start. | 0:21:49 | 0:21:52 | |
But Yellows, pay attention and listen carefully. | 0:21:52 | 0:21:55 | |
As soon as you hear the second siren, | 0:21:55 | 0:21:57 | |
that's your cue to start looking for those prize discs. | 0:21:57 | 0:22:00 | |
OK. You have some time. And that some time starts...now! | 0:22:00 | 0:22:05 | |
And away go the Reds. They're not afraid to get stuck in to the muck. | 0:22:05 | 0:22:11 | |
There goes the second siren to release the Yellows. | 0:22:11 | 0:22:13 | |
The Reds already have one prize disc in their net. | 0:22:16 | 0:22:19 | |
The Yellows bagged their first one. | 0:22:19 | 0:22:21 | |
ALARM GOES OFF | 0:22:24 | 0:22:26 | |
Oh! Oh, yeah. | 0:22:28 | 0:22:30 | |
I've done it again. I forgot to tell them | 0:22:30 | 0:22:32 | |
that every now and again, some more hideous gunge | 0:22:32 | 0:22:35 | |
comes down those pipes and tends to land on your head. | 0:22:35 | 0:22:39 | |
I think they've found that out now, but sometimes, | 0:22:39 | 0:22:42 | |
it does bring prize discs with it, so I think in the long run, | 0:22:42 | 0:22:46 | |
they'll be pleased...ish. | 0:22:46 | 0:22:49 | |
I really should look into my lab's drainage system. | 0:22:51 | 0:22:56 | |
It is a festival of gunge in there. | 0:22:56 | 0:22:59 | |
The Yellows look to be getting into their stride now, | 0:22:59 | 0:23:04 | |
scooping up prize discs all over the place. | 0:23:04 | 0:23:06 | |
Louie's lost his hat. Not good as it's raining gunge and prize discs. | 0:23:09 | 0:23:14 | |
I'll be honest, I'm not sure how the gunge has turned brown. | 0:23:14 | 0:23:19 | |
Another one for the Reds, there. Stan's checking for any duds. | 0:23:19 | 0:23:24 | |
It's a good tactic, that. | 0:23:24 | 0:23:26 | |
Yellows need to hurry up cos the Reds have the edge at the moment. | 0:23:26 | 0:23:29 | |
Alex slam dunks two prize discs. | 0:23:29 | 0:23:33 | |
Just in time. | 0:23:38 | 0:23:39 | |
CHEERING AND APPLAUSE | 0:23:39 | 0:23:41 | |
That is it, teams. Time is up. | 0:23:41 | 0:23:43 | |
Nice in there, isn't it? | 0:23:43 | 0:23:45 | |
Yeah. You've really been swimming in there, haven't you? OK. | 0:23:45 | 0:23:48 | |
Sorry about not warning you about the pipes. I forgot. Always do. | 0:23:48 | 0:23:53 | |
Right. Lab rats are counting up the prize discs right now as I speak. | 0:23:53 | 0:23:57 | |
So, for the Red Team, lab rat, how many have the reds got? | 0:23:57 | 0:24:00 | |
Show me with your little paws. | 0:24:00 | 0:24:02 | |
Eight prize discs for the Reds. | 0:24:02 | 0:24:04 | |
And now for the Yellows. | 0:24:04 | 0:24:05 | |
Lab rat, how many do we have? | 0:24:05 | 0:24:08 | |
Seven. It was so close. It's the Red team that win. | 0:24:08 | 0:24:11 | |
CHEERING AND APPLAUSE | 0:24:11 | 0:24:13 | |
Well done, Reds. Well done, Reds. | 0:24:15 | 0:24:18 | |
All of these prizes are yours. Let's have a look. | 0:24:18 | 0:24:21 | |
You're each taking home each of the prizes. Ready, Ninja Nan? | 0:24:21 | 0:24:25 | |
A toxic mutant. | 0:24:25 | 0:24:28 | |
A flying windcopter. | 0:24:28 | 0:24:30 | |
Planetarium. | 0:24:30 | 0:24:32 | |
Blood, Bones, Body Bits kit. | 0:24:32 | 0:24:35 | |
A science magic set. | 0:24:35 | 0:24:38 | |
An MP3 player. | 0:24:38 | 0:24:40 | |
You've done very well, very well, Reds. | 0:24:40 | 0:24:44 | |
A white wings glider kit. | 0:24:44 | 0:24:46 | |
And a lunar eclipse bedroom light. | 0:24:48 | 0:24:50 | |
Each of the Red Team, each of those prizes. | 0:24:50 | 0:24:52 | |
Well done, team. | 0:24:52 | 0:24:55 | |
Well done, team. Yellows, this is slightly difficult now because, | 0:24:55 | 0:25:00 | |
well, there's no nice way of saying this. | 0:25:00 | 0:25:02 | |
This is what you would have won. | 0:25:02 | 0:25:04 | |
Remote control mosquito. Lovely. | 0:25:04 | 0:25:07 | |
A lunar eclipse bedroom light. | 0:25:07 | 0:25:10 | |
Would have been nice. Toxic mutants. Each. | 0:25:10 | 0:25:12 | |
Would have been lovely. | 0:25:12 | 0:25:14 | |
Horrible Science books. Yeah. | 0:25:14 | 0:25:16 | |
Blood, Bones, Body Bits kit. | 0:25:16 | 0:25:20 | |
White wings glider kit. And the science magic set. | 0:25:20 | 0:25:25 | |
But don't worry, Yellows, because instead of taking them home, | 0:25:25 | 0:25:28 | |
you can blow them all up, because it is now time for Bidet Goes Bang. | 0:25:28 | 0:25:33 | |
Well, that time is upon us once again. | 0:25:41 | 0:25:45 | |
Reds, you're feeling great. Look at all these prizes! | 0:25:45 | 0:25:48 | |
You're taking them home Congratulations. | 0:25:48 | 0:25:50 | |
Yellows, sorry. How are you feeling? | 0:25:50 | 0:25:53 | |
-Disappointed but not disheartened. -OK. | 0:25:53 | 0:25:58 | |
Why didn't you win? What went wrong in the game, do you think? | 0:25:58 | 0:26:02 | |
Well, we all... In the gunge, it was hard to sort of walk. | 0:26:02 | 0:26:06 | |
It is difficult to move around and find those discs. | 0:26:06 | 0:26:09 | |
And I kept getting pulled down. | 0:26:09 | 0:26:11 | |
That doesn't help! | 0:26:11 | 0:26:12 | |
It was a close score, seven-eight, that really was. | 0:26:12 | 0:26:16 | |
It was a riot in there. Well, bad luck. Who's gonna do the plunger? | 0:26:16 | 0:26:20 | |
-All of us. -You'll share the blame together. | 0:26:20 | 0:26:23 | |
OK. Well, the moment is very nearly here. | 0:26:23 | 0:26:25 | |
I've seen plenty of good inventions go down the toilet | 0:26:25 | 0:26:28 | |
and most of my experiments go up in smoke, | 0:26:28 | 0:26:31 | |
but your prizes are about to do both at once | 0:26:31 | 0:26:33 | |
in my specially reinforced exploding bidet. | 0:26:33 | 0:26:36 | |
Prizes are in there ready, so, well, let's get on with it. Step forwards. | 0:26:36 | 0:26:41 | |
Lift the plunger, please, and be ready. | 0:26:41 | 0:26:43 | |
We will get you down. All right, Yellow Team? Audience... | 0:26:43 | 0:26:46 | |
ALL: Five. Four. Three. Two. One. | 0:26:46 | 0:26:51 | |
HUGE EXPLOSION | 0:26:51 | 0:26:54 | |
Unfortunately, we are out of time. Today you might say we've had | 0:27:03 | 0:27:06 | |
an in-depth look at particles and aerodynamics. | 0:27:06 | 0:27:09 | |
Or you might say we mucked about with go-karts and hairdryers. | 0:27:09 | 0:27:12 | |
They're both right but just tell your mum we did the first one. | 0:27:12 | 0:27:15 | |
See you next time. | 0:27:15 | 0:27:17 | |
Blast Lab was recorded before a live studio audience. | 0:27:27 | 0:27:30 | |
No lab rat was harmed during the filming. | 0:27:30 | 0:27:34 | |
Well, actually, one was but he was put down, painlessly. | 0:27:34 | 0:27:38 | |
