0:03:20 > 0:03:22- Hi.- - Pleased to meet you.
0:03:25 > 0:03:26- Hello, everyone.
0:03:27 > 0:03:28- Hello.
0:03:28 > 0:03:32- We've been trying out - my new cloud-tracking machine.
0:03:32 > 0:03:34- It works.
0:03:35 > 0:03:37- Hello, you three.
0:03:37 > 0:03:39- What are you doing here?
0:03:39 > 0:03:41- What are you doing here?- - Wadin invited us to meet her family.
0:03:42 > 0:03:44- What's for dinner? - What's for dinner?
0:03:45 > 0:03:47- Water. What else?
0:03:47 > 0:03:51- Water! It's water for dinner! - Water. I love it! Water!
0:03:51 > 0:03:57- Mum? Dad? Does Nimbwl - seem a little overexcited to you?
0:03:57 > 0:04:00- He's going to get the lightnings.
0:04:00 > 0:04:02- The lightnings?
0:04:02 > 0:04:06- No. Nimbwl's not going - to get the lightnings.
0:04:06 > 0:04:10- I love water. Mmm. Water. - Suck it up. Water for dinner.
0:04:10 > 0:04:12- BOOM CRACKLE
0:04:13 > 0:04:15- Oh! What was that?
0:04:15 > 0:04:16- I'm not sure.
0:04:16 > 0:04:18- I'm not sure.- - Maybe he's just got a rumbly tummy.
0:04:18 > 0:04:21- It's the lightnings.
0:04:21 > 0:04:24- Ooh! What are the lightnings?
0:04:25 > 0:04:27- Wheeee!
0:04:29 > 0:04:33- Have you been heating up - your bottom on warm air?
0:04:33 > 0:04:37- My bot... No. - No. No, I wasn't, I never.
0:04:37 > 0:04:38- BOOM CRACKLE
0:04:39 > 0:04:41- Was that a flash of lightning?
0:04:41 > 0:04:44- No. No, it wasn't me.
0:04:44 > 0:04:46- Oh, he has got the lightnings!
0:04:46 > 0:04:49- Oh, he has got the lightnings!- - He's got the lightnings.
0:04:49 > 0:04:50- Whee!
0:04:50 > 0:04:54- Yes, you're right. He has - the lightnings. The thunder...
0:04:55 > 0:04:56- Well, it's a giveaway.
0:04:56 > 0:05:00- What are the lightnings? - Sim, can I get the lightnings too?
0:05:01 > 0:05:03- No, Blero. You're not a cloud.
0:05:03 > 0:05:06- You see, Nimbwl's very cold inside.
0:05:06 > 0:05:11- In fact, he's so cold inside - that his raindrops are freezing.
0:05:11 > 0:05:13- Oh, poor Nimbwl.
0:05:13 > 0:05:16- It's normal for some clouds - to be cold inside.
0:05:16 > 0:05:20- The problem is that, when he - warms his bottom on hot air...
0:05:20 > 0:05:24- ..his insides get all excited - and go completely topsy-turvy.
0:05:24 > 0:05:29- Because he's excited inside, all the - hot and cold air, water and ice...
0:05:29 > 0:05:31- ..is moving about - and mixing together.
0:05:32 > 0:05:35- All that churning and mixing - makes electricity.
0:05:35 > 0:05:37- When there's enough electricity...
0:05:38 > 0:05:40- ..it makes lightning!
0:05:40 > 0:05:41- Wheeee!
0:05:43 > 0:05:44- Did you see that?
0:05:45 > 0:05:47- I've got the lightnings!
0:05:47 > 0:05:51- Everybody, aboard the Cloudship. - We should follow him.
0:05:52 > 0:05:54- Wadin, you go - in the Cloudship and help.
0:05:55 > 0:05:58- We'll wait here - in case he comes back this way.
0:06:02 > 0:06:04- THUNDER CRASH
0:06:04 > 0:06:06- Oh! Lightning is so exciting.
0:06:07 > 0:06:13- Yes, it's amazing, Blero. And as - long as you're inside, nice and dry.
0:06:13 > 0:06:17- And not standing - under something tall, like a tree.
0:06:18 > 0:06:22- It's like a fireworks show.
0:06:22 > 0:06:24- Bala-bala-boom-boom!
0:06:24 > 0:06:29- So, Nimbwl's insides - are all excited and mixing about...
0:06:30 > 0:06:33- ..and that's why - he's making lightning.
0:06:33 > 0:06:35- That's right, Dylan.
0:06:36 > 0:06:39- Hmm. So, what makes the noise - of the thunder?
0:06:40 > 0:06:42- Ah, well, - lightning's very, very hot.
0:06:43 > 0:06:45- In fact, - it's so hot it makes the air move.
0:06:46 > 0:06:49- And the air moves so fast - that it makes a noise.
0:06:49 > 0:06:52- And that noise is thunder.
0:06:52 > 0:06:57- Listen. Now the thunder is coming - a long time after the lightning.
0:06:57 > 0:07:01- That means that Nimbwl's - moving away from us.
0:07:01 > 0:07:05- The sound of thunder moves slower - than the flash of the lightning.
0:07:06 > 0:07:11- If Nimbwl's a long way away, we see - the flash before we hear thunder.
0:07:12 > 0:07:14- Do you know where Nimbwl's going?
0:07:14 > 0:07:21- According to my cloud-tracking - machine, Nimbwl's heading towards...
0:07:21 > 0:07:23- ..the ice rink.
0:07:23 > 0:07:28- That's where the grand finale - of Ocido Sports Day is happening!
0:07:28 > 0:07:33- If Nimbwl gets there, Ocido Sports - Day will have to be called off!
0:07:33 > 0:07:36- For the first time ever.
0:07:36 > 0:07:40- We have to calm Nimbwl down - before he gets there.
0:07:40 > 0:07:42- Let's go to the ice rink!
0:07:51 > 0:07:53- THUNDER CRACKS
0:07:54 > 0:07:57- Nimbwl sounds very close.
0:07:57 > 0:08:01- I know! Let's just pick up the - ice rink and move it somewhere safe.
0:08:02 > 0:08:05- How will we pick up the ice rink, - Blero?
0:08:05 > 0:08:08- Using Sam's amazing - ice-rink-moving machine.
0:08:09 > 0:08:13- I haven't invented an amazing - ice-rink-moving machine.
0:08:13 > 0:08:15- You've got a few minutes.
0:08:15 > 0:08:19- Nimbwl's excited - because he warmed his bottom up.
0:08:20 > 0:08:25- Yes, if Nimbwl's top, middle and - bottom are the same temperature...
0:08:25 > 0:08:27- ..they won't be mixing up.
0:08:27 > 0:08:29- He'll be calm inside.
0:08:29 > 0:08:34- Bring out your cloud bottom cooling - machine, before it's too late!
0:08:34 > 0:08:36- Blero!
0:08:38 > 0:08:41- Now I've got a cold bottom.
0:08:41 > 0:08:42- Now I've got a cold bottom.- - Of course!
0:08:42 > 0:08:47- If we blow cold air - from the ice rink towards Nimbwl...
0:08:47 > 0:08:52- ..we can cool his bottom half down - and cure his lightnings.
0:08:55 > 0:08:58- Ready, Wadin? Ready, Swn?
0:08:59 > 0:09:00- Wheeee!
0:09:02 > 0:09:04- I've got the lightnings!
0:09:05 > 0:09:06- Here he comes!
0:09:07 > 0:09:12- Swn! Wadin! When I say now, - blow icy air at Nimbwl's bottom!
0:09:12 > 0:09:16- Lightning. Whoa. - Who wants to see some lightning?
0:09:16 > 0:09:17- Look, I'm flashing my bottom.
0:09:17 > 0:09:19- Look, I'm flashing my bottom.- - Now!
0:09:21 > 0:09:24- Ooh, ooh, ooh! - Cold, cold! Cold bottom!
0:09:24 > 0:09:27- O-o-o-o-oh. Oh, that's better.
0:09:27 > 0:09:28- O-o-o-o-oh.
0:09:31 > 0:09:33- Have the lightnings gone?
0:09:33 > 0:09:35- Have the lightnings gone?- - Yes, they have. Phew.
0:09:35 > 0:09:38- I'm never going to - warm my bottom on warm air again.
0:09:38 > 0:09:40- I've said that before, - but I promise.
0:09:41 > 0:09:43- Ha-ha. It's OK, Nimbwl.
0:09:44 > 0:09:48- Some clouds get the lightnings - from time to time.
0:09:48 > 0:09:50- It was great!
0:09:50 > 0:09:54- Thank you for your help, everyone. - Nimbwl?
0:09:54 > 0:09:56- We should go home for dinner now.
0:09:57 > 0:10:00- OK, Wadin. - Thank you, everyone. See you soon.
0:10:00 > 0:10:03- Bye, Wadin. Bye, Nimbwl.
0:10:04 > 0:10:06- I've had a really exciting day.
0:10:06 > 0:10:10- I want to see if there's - still lightning and thunder at home.
0:10:11 > 0:10:12- Bye!
0:10:15 > 0:10:20- Zap! Lightning! Boom! Thunder!
0:10:21 > 0:10:23- So, lightning is electricity.
0:10:23 > 0:10:26- And thunder is the sound - of the air moving. Hmm.
0:10:27 > 0:10:34- And together they are the messiest, - noisiest weather I've ever seen!
0:10:34 > 0:10:35- Bye-bye!
0:10:39 > 0:10:41- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
