0:33:06 > 0:33:08This is Blue Peter but mini.
0:33:08 > 0:33:12Expect epic adventures, makes, bakes, badges, pets, presenters
0:33:12 > 0:33:14and your host.
0:33:14 > 0:33:19We've only got five minutes so get ready for your Blue Peter adventure.
0:33:19 > 0:33:21Goodwood Circuit.
0:33:21 > 0:33:25One of the most famous tracks in British racing history.
0:33:25 > 0:33:27Thousands of the world's fastest cars
0:33:27 > 0:33:30have been around its twists and turns.
0:33:30 > 0:33:32But today the cars will be a little different.
0:33:32 > 0:33:34This is Goblin Racing.
0:33:38 > 0:33:40Welcome to Formula Goblin.
0:33:40 > 0:33:42RADZI ROARS LOUDLY
0:33:42 > 0:33:45- Radzi, what are you doing? - I'm doing an impression of a Goblin.
0:33:45 > 0:33:47No. No, the cars are called the G...
0:33:47 > 0:33:49You've ruined my intro now. I'm telling Lindsey.
0:33:49 > 0:33:52What? No, Barney, I just meant that...
0:33:53 > 0:33:56Formula Goblin is a project which challenges 90 schools to
0:33:56 > 0:34:01build and race their very own green, battery-powered cars.
0:34:01 > 0:34:05And a soaking wet racetrack won't stop us from competing too.
0:34:05 > 0:34:09Yes! Look at those things. I want to get in one right now
0:34:09 > 0:34:11- cos, Barney, I really think... - Radzi, shush those lips.
0:34:11 > 0:34:13We can't drive one till we've built it.
0:34:13 > 0:34:16- And that was two weeks ago. - Time travel?
0:34:18 > 0:34:22We're here in Hampshire to see the final build of two Goblin cars.
0:34:22 > 0:34:25There'll be two teams, and two Blue Peter presenters.
0:34:25 > 0:34:27- So, you know what that means? - I know what that means.
0:34:27 > 0:34:30- Means I'm going to win. - We'll see about that.
0:34:30 > 0:34:32I'm joining the Green Goblins.
0:34:32 > 0:34:35And I've been recruited by the Leaping Leopards.
0:34:35 > 0:34:37- ALL:- Yeah!
0:34:37 > 0:34:40Each team has been sent a kit to assemble.
0:34:40 > 0:34:43The idea is to build a car that produces no air pollution
0:34:43 > 0:34:47and they are encouraged to use recycled parts.
0:34:47 > 0:34:49So, this is from a bicycle.
0:34:49 > 0:34:53We tested a couple of bicycle brakes and this was the strongest one.
0:34:53 > 0:34:55It's really about the engineering, isn't it?
0:34:55 > 0:34:58- Yeah.- It's about making decisions, seeing how they work,
0:34:58 > 0:35:00- and, if they don't work, making them better.- Yeah.
0:35:00 > 0:35:03'Tech's all well and good, Barney, but it has to look amazing as well.'
0:35:03 > 0:35:05So, what are we thinking in terms of decoration?
0:35:05 > 0:35:09Well, we've got our leopard print tape, we've got our bodywork,
0:35:09 > 0:35:12we've been spending the last few weeks just painting all this.
0:35:12 > 0:35:13'And the final touch.'
0:35:13 > 0:35:15Yes!
0:35:15 > 0:35:17Now we are in business. Evie, are you happy?
0:35:17 > 0:35:19Yeah, it really stands out.
0:35:19 > 0:35:22- Team, are we happy? - ALL:- Yes.
0:35:22 > 0:35:23Let's do it.
0:35:25 > 0:35:28We'll be competing against each other in three different races.
0:35:28 > 0:35:30First is the sprint.
0:35:30 > 0:35:33Which Goblin is fastest over 50 metres?
0:35:33 > 0:35:35- This is an epic challenge.- Oh, yes.
0:35:35 > 0:35:38See you at the finish line, slow coach.
0:35:38 > 0:35:40Radzi, your car's that way, mate.
0:35:40 > 0:35:42I knew that. I knew that.
0:35:47 > 0:35:49'I'm off to a great start.'
0:35:51 > 0:35:53'Hang on, Barney. I'm catching up.'
0:35:56 > 0:35:59'I'm not sure how, but I pipped Barney on the line
0:35:59 > 0:36:02'and my team-mates can't believe it.'
0:36:02 > 0:36:04'Yeah, well done, Radzi.
0:36:04 > 0:36:06'But speed isn't everything.
0:36:06 > 0:36:09'Our next race is about skill and control.'
0:36:09 > 0:36:11'Ah, yes. Bring on the slalom.
0:36:11 > 0:36:15'We have to drive between these cones and finish in this box.
0:36:15 > 0:36:18'And there's a penalty for every single cone we hit.
0:36:20 > 0:36:23'I'm first, and it's proving difficult in these wet conditions.'
0:36:23 > 0:36:25Ahhh!
0:36:25 > 0:36:28'I think I've knocked a few cones but my team seem confident.'
0:36:28 > 0:36:33- Great job!- Thank you, high five! Yes! Yes!
0:36:33 > 0:36:36'My turn and I am in my element.'
0:36:39 > 0:36:40- Well done, Barn.- Coming through!
0:36:40 > 0:36:43- I hit a couple of cones, though. - Oh, did you?- What?- I think I hit...
0:36:43 > 0:36:46- You only hit two. - I only hit two. Radzi hit 70.
0:36:46 > 0:36:49'Not quite 70, Barney, but more than you,
0:36:49 > 0:36:51'making it 1-1 on the challenges.'
0:36:51 > 0:36:52'So, it all comes down to this.
0:36:52 > 0:36:55'Cue the slow-mo walk.
0:36:55 > 0:36:58'Each team will take on one lap of this legendary track.
0:36:58 > 0:37:03'That's 2.4 miles of speed, turns and pure skill.
0:37:03 > 0:37:05'The winner takes all.'
0:37:05 > 0:37:08Guys, you've put your faith in me, you've built me an amazing car.
0:37:08 > 0:37:11PMA. Positive mental attitude.
0:37:11 > 0:37:12- ALL:- YEAH!
0:37:12 > 0:37:14- ALL:- Go Goblins!
0:37:26 > 0:37:28Here we go!
0:37:28 > 0:37:32And Barney has taken a very strong lead.
0:37:32 > 0:37:35- Come on, come on, come on, come on, come on, come on!- No!
0:37:35 > 0:37:38'What a comeback - I've passed Barney.'
0:37:38 > 0:37:41'Not for long, Radz.'
0:37:41 > 0:37:43- Oh!- Ooh, that was close.
0:37:43 > 0:37:45I'm trying to stay quiet and concentrate
0:37:45 > 0:37:47and Radzi's just making a lot of noise.
0:37:47 > 0:37:51- Hello?- I think he thinks that making noise makes him go faster.- Urgh.
0:37:51 > 0:37:53Uh-oh.
0:37:53 > 0:37:55Erm, I may have a battery problem.
0:37:55 > 0:37:56I'm in the lead!
0:37:56 > 0:37:58'Oh, no. A battery glitch has left me trailing.'
0:37:58 > 0:37:59Yes!
0:37:59 > 0:38:03The home straight. Anything could happen.
0:38:03 > 0:38:04'I need to catch Radzi.'
0:38:06 > 0:38:08Come on!
0:38:08 > 0:38:11Whoa. Who-ooa.
0:38:11 > 0:38:13It's going to be a close finish.
0:38:13 > 0:38:15It could be anybody's race.
0:38:15 > 0:38:17Ah-ha-ha!
0:38:17 > 0:38:20'And it's down to a photo finish.'
0:38:20 > 0:38:22Second place...
0:38:22 > 0:38:25- was Radzi. - Oo-oh!
0:38:25 > 0:38:27CHEERING
0:38:27 > 0:38:28He's off!
0:38:32 > 0:38:35It came down to that much. That much!
0:38:35 > 0:38:38Only one place for the Green Goblins to be sat and that's right here
0:38:38 > 0:38:41- in first place. Come on, Radzi, hand it over.- Fine. Do you know what?
0:38:41 > 0:38:43fair play, mate... Old school, through the hair!
0:38:43 > 0:38:45- No, in all seriousness... - Thank you.
0:38:45 > 0:38:47..well done, mate, you did very well.
0:38:47 > 0:38:50It's down to this incredible team. You built a brilliant car, well done.
0:38:50 > 0:38:53And Lewis Hamilton, watch out, some future champions right here.
0:38:53 > 0:38:55- Absolutely.- Not here, though.
0:38:55 > 0:38:57How about a cheer, everybody?
0:38:57 > 0:38:59CHEERING We won!
