0:00:35 > 0:00:37- # Blero goes to Ocido! #
0:00:40 > 0:00:43- Vroom.
0:00:45 > 0:00:47- Oh, no, that's too fast.
0:00:48 > 0:00:49- Ah!
0:00:50 > 0:00:52- Watch out for that sandwich. Uh-oh.
0:00:54 > 0:00:55- Mind the socks.
0:00:55 > 0:00:58- Oh...! Truck-a-roony.
0:00:58 > 0:01:01- Who's driving this truck? - Yes, it's Blero.
0:01:02 > 0:01:04- He's incredible. He's amazing.
0:01:04 > 0:01:07- He's the fastest ever. - He's going to win.
0:01:07 > 0:01:10- He's, he's, he's... stopped.
0:01:11 > 0:01:13- Hmm... What's wrong with it?
0:01:14 > 0:01:17- Hmm, why isn't it working?
0:01:17 > 0:01:21- Ha! When you need to know, - go to Ocido!
0:01:30 > 0:01:31- Whee!
0:01:33 > 0:01:35- DOORBELL RINGS
0:01:36 > 0:01:39- Oh, it's you. Hi, Blero.
0:01:39 > 0:01:42- Hi, Sian. Hi, Dylan. Did you think - I was going to be someone else?
0:01:43 > 0:01:46- Well, yes. - We've been waiting for Sim and Sam.
0:01:46 > 0:01:47- But they're a bit late.
0:01:48 > 0:01:52- I've been trying to call - but my communicator isn't working.
0:01:53 > 0:01:55- Come in and I'll show you.
0:01:57 > 0:01:59- Hello, Sim!
0:02:00 > 0:02:02- STATIC CRACKLES
0:02:02 > 0:02:06- Hello, Sian. Hello... Sian. - Can... you... hear me?
0:02:08 > 0:02:09- See?
0:02:09 > 0:02:12- That is the messiest - speaking I've ever heard.
0:02:12 > 0:02:16- It's just bits and pieces of words. - Hmm, maybe I can fix it.
0:02:24 > 0:02:27- Ha-ha! Try it now.
0:02:27 > 0:02:30- Hello, Sam, can you hear me?
0:02:30 > 0:02:32- STATIC CRACKLES
0:02:33 > 0:02:37- Nothing. Maybe the shaking - wasn't such a good idea.
0:02:38 > 0:02:39- Hmm...
0:02:39 > 0:02:42- Oh, that's Sim and Sam now. Come on!
0:02:43 > 0:02:46- Hi, Sian. Hi, Dylan. Hello, Blero.
0:02:46 > 0:02:47- Hi, Sim, Sam, Swn!
0:02:48 > 0:02:53- Sian, is there something wrong - with your communicator?
0:02:53 > 0:02:56- I think so. - Your words were all chopped up.
0:02:57 > 0:03:01- So were yours. Have you tried - turning it on and off?
0:03:01 > 0:03:02- Yes.
0:03:02 > 0:03:04- Yes.- - We tried shaking it too.
0:03:05 > 0:03:06- Did that work?
0:03:06 > 0:03:08- Did that work?- - No, but it was lots of fun.
0:03:09 > 0:03:11- Time to hit the lab, everyone.
0:03:14 > 0:03:15- There we are.
0:03:16 > 0:03:18- Let's try a new battery.
0:03:21 > 0:03:23- Try that.
0:03:25 > 0:03:26- Hi!
0:03:27 > 0:03:30- Can... you... hear... me?
0:03:30 > 0:03:32- Oh! It's still not working.
0:03:33 > 0:03:35- There's something wrong - with the circuit.
0:03:36 > 0:03:40- Oh! Circus? Did you say circus? - I love the circus!
0:03:40 > 0:03:44- I love the clowns, the acrobats, - the tightrope walkers...
0:03:44 > 0:03:46- And the clowns and the...
0:03:46 > 0:03:50- Not circus, Blero! Circuit.
0:03:50 > 0:03:52- Electrical circuit.
0:03:52 > 0:03:57- We use electricity - to power lots of different things...
0:03:57 > 0:04:02- ..and everything that uses - electricity has a circuit in it.
0:04:02 > 0:04:07- The circuit is how the electricity - goes around the device.
0:04:07 > 0:04:08- Follow me.
0:04:09 > 0:04:11- The doorbell button - is part of the circuit...
0:04:12 > 0:04:15- ..that goes all the way - into the house through the buzzer.
0:04:15 > 0:04:18- Your assistance, please, Zoom.
0:04:18 > 0:04:21- It all starts here in the battery.
0:04:21 > 0:04:25- The battery - is where the electricity is stored.
0:04:25 > 0:04:30- From here, it races all the way - round to the buzzer here...
0:04:30 > 0:04:33- ..when you press the button, - like so.
0:04:33 > 0:04:37- Oh! I can see - the electricity going round.
0:04:37 > 0:04:41- But look what happens - if there's a break in the circuit.
0:04:42 > 0:04:44- The electricity stops.
0:04:44 > 0:04:46- No buzzer.
0:04:46 > 0:04:50- Hmm. Is that what's happened - to my communicator?
0:04:50 > 0:04:52- I think so.
0:04:52 > 0:04:55- Can't you just open it up - and fix it?
0:04:55 > 0:04:58- Ah, well, - there's a bit of a problem there.
0:04:58 > 0:05:03- Er, when I designed it I didn't - think it would ever go wrong.
0:05:04 > 0:05:06- So, there isn't a way to open it up.
0:05:06 > 0:05:08- Because it can't possibly go wrong.
0:05:09 > 0:05:11- But it did go wrong!
0:05:12 > 0:05:13- Hmm.
0:05:13 > 0:05:16- Maybe if I look - through this tiny hole...
0:05:17 > 0:05:20- ..I could see - where the break in the circuit is.
0:05:20 > 0:05:21- Er, what hole?
0:05:21 > 0:05:22- Er, what hole?- - This one.
0:05:22 > 0:05:23- Look!
0:05:24 > 0:05:26- Oh, that one.
0:05:27 > 0:05:30- I put that one in there - for just this sort of emergency.
0:05:30 > 0:05:31- Shameless.
0:05:31 > 0:05:33- Shameless.- - You can't see inside, though.
0:05:34 > 0:05:37- If we were tiny enough, - we could go inside.
0:05:37 > 0:05:40- And fix it! Fix the circuit break.
0:05:41 > 0:05:46- Yes, what a good idea. We could use - my shrink-a-sizer to make you tiny.
0:05:46 > 0:05:49- We'll need Ocidoodle, too.
0:05:49 > 0:05:52- Yes! Bala-bala-boom-boom!
0:06:00 > 0:06:05- The shrink-a-sizer will make us tiny - enough to fit into the communicator.
0:06:06 > 0:06:07- Shrink away, Sim.
0:06:07 > 0:06:12- I'll keep in touch with you - on the Ocidoodle walkie-talkie.
0:06:12 > 0:06:14- Bala-bala-boom-boom!
0:06:14 > 0:06:18- OK, Sam. Here we go. Shrink-a-size!
0:06:26 > 0:06:33- Carefully place the Ocidoodle - through the hole, like so.
0:06:34 > 0:06:36- Let's ski-doodle, Ocidoodle!
0:06:39 > 0:06:41- Oh, this is amazing!
0:06:43 > 0:06:45- It's like a giant city.
0:06:45 > 0:06:47- With lots of streets.
0:06:47 > 0:06:51- Not streets, those are the circuits.
0:06:52 > 0:06:53- What all those big things?
0:06:54 > 0:06:56- They are parts of the circuit.
0:06:56 > 0:06:58- They have complicated names.
0:06:58 > 0:07:05- Names like resistors, - diodes, switches...
0:07:05 > 0:07:08- ..and capacitors.
0:07:08 > 0:07:09- Capaci-pa-pators?
0:07:10 > 0:07:16- They slow the electricity down, - or hold it, or speed it up.
0:07:16 > 0:07:17- What do we do now?
0:07:17 > 0:07:19- Find the battery.
0:07:19 > 0:07:23- That's where the electricity is - stored and where the circuit starts.
0:07:24 > 0:07:25- Let's go!
0:07:25 > 0:07:27- Battery, here we come!
0:07:35 > 0:07:39- Oh, look! There's the battery.
0:07:39 > 0:07:41- What are all those red things?
0:07:41 > 0:07:43- That's the electricity.
0:07:43 > 0:07:47- See, it's coming out of the battery.
0:07:47 > 0:07:49- Yes, and it all goes off - down the circuit.
0:07:50 > 0:07:55- If we follow the electricity, it - will take us to the circuit break.
0:07:56 > 0:07:58- What are we waiting for? Let's go!
0:08:07 > 0:08:11- Look! What's happening?
0:08:12 > 0:08:15- It's like they can't go any further.
0:08:15 > 0:08:18- Over there! It's all dark.
0:08:19 > 0:08:22- So, this is where the break must be.
0:08:28 > 0:08:29- Ha-ha-ha!
0:08:31 > 0:08:33- This is ticklish.
0:08:33 > 0:08:36- Look at that! - It looks like a bridge.
0:08:36 > 0:08:39- Whatever it is, it looks broken.
0:08:39 > 0:08:41- That's called a conductor.
0:08:42 > 0:08:45- That looks like the break - in the circuit.
0:08:45 > 0:08:48- You're right. - The electricity can't get across.
0:08:49 > 0:08:50- We'd better fix it.
0:08:50 > 0:08:53- Oh, can I do it? - Please, please, please?
0:08:53 > 0:08:55- Can I, can I, can I? Me, me, me!
0:08:55 > 0:08:57- Go on, Blero.
0:08:57 > 0:08:59- Hoo-hoo! Ha-ha!
0:09:08 > 0:09:11- Whoa! They're unstoppable.
0:09:18 > 0:09:20- Did we fix it, Sam?
0:09:20 > 0:09:23- There's only one way to find out.
0:09:23 > 0:09:27- Sam calling Sim. Sam calling Sim.
0:09:27 > 0:09:29- Hello, Sam!
0:09:29 > 0:09:33- Sim, can you call me - on Sian's communicator, please?
0:09:34 > 0:09:36- Yes, of course. Here goes.
0:09:36 > 0:09:42- Hello, Sam, Blero, Dylan and Sian. - Can you hear me?
0:09:42 > 0:09:45- Yes, loud and clear!
0:09:45 > 0:09:47- No need to shout.
0:09:47 > 0:09:50- Mission accomplished.
0:09:50 > 0:09:52- Hooray!
0:09:52 > 0:09:55- Right, resize us, Sim.
0:10:00 > 0:10:02- Oh, well done, everyone.
0:10:02 > 0:10:06- Well done, Blero. He's the one - who fixed the circuit break.
0:10:06 > 0:10:09- Hey, I just remembered! - I've got more things to fix.
0:10:10 > 0:10:12- It's time I went home. - Bye, everyone.
0:10:12 > 0:10:14- Bye, Blero! You were great.
0:10:16 > 0:10:19- Now, what did Sam say to try first?
0:10:20 > 0:10:23- Oh, I know! Try new batteries.
0:10:23 > 0:10:26- Hmm. One battery. Two batteries.
0:10:26 > 0:10:28- And now...
0:10:30 > 0:10:31- Bala-bala-boom-boom!
0:10:33 > 0:10:36- Huh! This circuit - wasn't broken after all.
0:10:36 > 0:10:39- It just needed new batteries. - Bye-bye!
0:10:39 > 0:10:41- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
