0:02:13 > 0:02:15- This roller-coaster - needs urgent repairs.
0:02:16 > 0:02:18- Really? Can we have a go? - I mean, can we see?
0:02:19 > 0:02:20- Oh, no! It's horrible.
0:02:21 > 0:02:24- It goes up and down and round - and round and up and over...
0:02:25 > 0:02:27- ..and down and up and round and...
0:02:28 > 0:02:30- It's supposed to, silly.
0:02:30 > 0:02:34- No, the problem is the rails - at the top are very old...
0:02:34 > 0:02:36- ..and aren't safe any more.
0:02:36 > 0:02:38- My rail-checker never lies.
0:02:38 > 0:02:42- We need to change them. - No more rides until we do!
0:02:43 > 0:02:44- Oh, boo.
0:02:45 > 0:02:47- How are we going to - change the rails?
0:02:47 > 0:02:50- It's a bit, er, high.

0:02:59 > 0:03:04- Oh, thanks. We'll make sure - no-one goes on the roller-coaster.
0:03:04 > 0:03:07- Let's Oci-go!
0:03:08 > 0:03:10- No, sorry. No entry.
0:03:10 > 0:03:13- Health and safety rules, you see.
0:03:16 > 0:03:18- Hmmm. Where's Al Tal?
0:03:18 > 0:03:22- Must be around here somewhere? Al!
0:03:22 > 0:03:26- Al Tal! Where are you?
0:03:30 > 0:03:33- Hello, Al. - I always forget how tall you are.
0:03:33 > 0:03:38- Can you come and help us - fix the roller-coaster, please?
0:03:40 > 0:03:42- OK, then. Follow us!
0:03:47 > 0:03:51- Blero, do we have to go so fast?
0:03:51 > 0:03:53- The sooner we get back...
0:03:54 > 0:04:00- ..the sooner Al will fix it, - and the sooner we can have a ride!
0:04:05 > 0:04:06- Blero!
0:04:06 > 0:04:09- Blero!- - Don't forget about Al!
0:04:09 > 0:04:10- Sorry, Al!
0:04:10 > 0:04:13- I'll slow down a bit.
0:04:16 > 0:04:19- Wow, Al! Are you OK?
0:04:21 > 0:04:24- Can we go a bit more slowly, Blero?
0:04:24 > 0:04:27- OK. Next stop - roller-coaster!
0:04:27 > 0:04:29- Blero!
0:04:32 > 0:04:35- That was quick. Hello, Al!
0:04:35 > 0:04:41- Can you help us to take off the - old rails and put in these new ones?
0:04:49 > 0:04:51- Oh, no!
0:04:51 > 0:04:54- Al, are you OK?
0:04:56 > 0:04:58- Look out!
0:04:58 > 0:05:01- Stay there! Don't get up.
0:05:01 > 0:05:03- Al's gone all wobbly again.
0:05:03 > 0:05:06- Al's gone all wobbly again.- - Again! Did this happen before?
0:05:06 > 0:05:11- It wasn't my fault, but we were - trying to get here super fast...
0:05:11 > 0:05:15- ..and we spun around - and around and up and down...
0:05:15 > 0:05:17- OK, maybe it was a bit my fault.
0:05:18 > 0:05:22- I know what's happened. Stan is - having problems with his balance.
0:05:23 > 0:05:25- Bal-ance? What's that?
0:05:25 > 0:05:28- Balance is what keeps you - standing up...
0:05:28 > 0:05:32- ..and stops you from falling over - when you walk along or run...
0:05:32 > 0:05:35- ..or turn around - or climb on something.
0:05:35 > 0:05:39- But his feet are fine. - His legs are fine.
0:05:39 > 0:05:41- His knees are fine.
0:05:42 > 0:05:46- Actually, your balance is controlled - by something in your head.
0:05:47 > 0:05:48- Huh?
0:05:50 > 0:05:56- Your head is where your brain is. - Your brain is your body's computer.
0:05:56 > 0:06:01- It collects information - from your eyes and ears and nose...
0:06:01 > 0:06:05- ..and hands and feet, - then tells your body what to do.
0:06:05 > 0:06:08- Blero, can you stand on one leg?
0:06:08 > 0:06:11- I'm the best one-leg-stander ever!
0:06:11 > 0:06:13- Do you know how you do it?
0:06:13 > 0:06:16- Your brain tells your body - how to stay upright...
0:06:16 > 0:06:20- ..without you even having - to think about it.
0:06:20 > 0:06:23- Now, try it with your eyes closed.
0:06:26 > 0:06:27- I'm still standing.
0:06:28 > 0:06:31- Although your eyes help you balance, - your ears do, too.
0:06:32 > 0:06:33- My ears?
0:06:33 > 0:06:35- My ears?- - But you don't hear balance.
0:06:35 > 0:06:38- That's right, Dylan. - Your ears feel it.
0:06:39 > 0:06:42- Your ears are very important - in keeping your balance.
0:06:43 > 0:06:46- I think Al is OK, - but I need to check.
0:06:49 > 0:06:53- Can we have a look - inside your head, please?
0:06:53 > 0:06:58- Inside his head?! - It won't hurt him, will it, Sam?
0:06:58 > 0:06:59- Inside his head?! - It won't hurt him, will it, Sam?- - It won't hurt a bit.
0:06:59 > 0:07:03- Brilliant. Then we can get back - to work on the roller-coaster!
0:07:04 > 0:07:07- How do we get in?
0:07:07 > 0:07:09- Ah! Leave it to me.
0:07:11 > 0:07:17- Well done, Dylan. Blero, remember, - please don't touch anything.
0:07:17 > 0:07:19- Of course!
0:07:19 > 0:07:21- What?
0:07:22 > 0:07:26- Whoa! This is amazing!
0:07:28 > 0:07:31- Careful now. Keep your balance.
0:07:31 > 0:07:36- I still don't know how my ears - are keeping me from falling over.
0:07:37 > 0:07:38- Well, Blero, look, that's how!
0:07:39 > 0:07:44- Your ear has a special bit inside - called the inner ear.
0:07:44 > 0:07:47- That's what's used for balance.
0:07:47 > 0:07:50- Al has an inner ear - that works the same as yours.
0:07:50 > 0:07:54- When you move up, down or sideways, - the liquid in those tubes...
0:07:55 > 0:07:59- ..moves too and those sensors tell - your brain which way you're moving.
0:08:00 > 0:08:03- Your brain tells - your legs, knees, feet, toes...
0:08:03 > 0:08:06- ..what to do to keep your balance.
0:08:06 > 0:08:11- When I do this, I can feel my - feet and legs and knees and toes...
0:08:11 > 0:08:15- ..and everything - all stopping me from falling over.
0:08:15 > 0:08:19- Your brain is telling your body - what to do.
0:08:19 > 0:08:25- Al's inner ear is fine. - I think you just made him dizzy.
0:08:25 > 0:08:28- Diz-zee? That's a lovely word.
0:08:28 > 0:08:31- Dizzy. Diz-zee. Dee-zee.
0:08:31 > 0:08:33- What does it mean?
0:08:34 > 0:08:38- If you spin around too much, - your inner ear can get confused...
0:08:38 > 0:08:40- ..and sends the wrong signals - to your brain.
0:08:41 > 0:08:43- That's when you feel dizzy.
0:08:43 > 0:08:46- Al, you just got diz-zee.
0:08:46 > 0:08:49- Blero, let's tell him to his face.
0:08:51 > 0:08:56- Al, you just got dizzy, - so you're OK.
0:08:58 > 0:09:02- No more spinning, twisting, - twirling, or whirling around, OK?
0:09:03 > 0:09:08- Now that you are better, - let's fix that roller-coaster.
0:09:13 > 0:09:15- Er, left a bit.
0:09:15 > 0:09:16- Down a bit.
0:09:16 > 0:09:17- Down a bit.- - That's it!
0:09:20 > 0:09:24- Thank you for helping to fix - the roller-coaster, Al.
0:09:25 > 0:09:26- It's as good as new.
0:09:30 > 0:09:33- Are you sure you want to do this?
0:09:33 > 0:09:36- Yes! I can't wait to get dizzy.
0:09:44 > 0:09:46- Whoa...! Waaaaaah!
0:10:02 > 0:10:04- I'm dizzy!
0:10:04 > 0:10:05- Me too.
0:10:06 > 0:10:09- My inner ear is confused.
0:10:10 > 0:10:14- That was an amazing ride! Thanks - for fixing the roller-coaster.
0:10:18 > 0:10:21- Time to go. See you next time! Bye!
0:10:22 > 0:10:23- Bye, Blero!
0:10:23 > 0:10:27- Wheeeee! Ho-ho! Phew.
0:10:27 > 0:10:29- I feel dizzy again.
0:10:29 > 0:10:33- All that spinning around - has made my inner ear confused.
0:10:33 > 0:10:36- Whoa! Hee-hee-hee-hee.
0:10:36 > 0:10:39- Time for a sit down. Bye, everyone!
0:10:39 > 0:10:42- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
