0:00:45 > 0:00:48I love spinning. Round and round and round
0:00:48 > 0:00:54and round and round and round... Whoa!
0:00:54 > 0:00:55I feel funny.
0:00:55 > 0:00:59That was really weird. What happened?
0:00:59 > 0:01:00Whoops!
0:01:00 > 0:01:04Hmmm. When you need to know, go to Okido!
0:01:14 > 0:01:18Hello, Zoe. Hello, Felix. Huh?
0:01:18 > 0:01:19What are you doing?
0:01:19 > 0:01:23Messy! We were ballet dancing.
0:01:23 > 0:01:26Oh, I'm brilliant at ballet! Watch.
0:01:26 > 0:01:28And, twirl...
0:01:28 > 0:01:30the pirouette...
0:01:30 > 0:01:31and finish.
0:01:31 > 0:01:36- Wow! That was, erm, different. - BEEPING
0:01:36 > 0:01:38- Oh, it's Zim. Hi, Zim.- Hi, Zim.
0:01:38 > 0:01:42Hi, everyone. Can you come to Magnetto Zone, please?
0:01:42 > 0:01:44We need your help with the roller-coaster.
0:01:44 > 0:01:46Of course! We're on our way.
0:01:46 > 0:01:48I love roller-coasters!
0:01:48 > 0:01:50WHISTLES
0:01:52 > 0:01:54HORN SOUNDS
0:01:54 > 0:01:56Let's ski-doodle, Okidoodle!
0:02:03 > 0:02:06Where are Zim, Zam, and Zoom?
0:02:06 > 0:02:07ZIM SCREAMS IN TERROR
0:02:09 > 0:02:15A-ha! I knew it. This roller-coaster needs urgent repairs.
0:02:15 > 0:02:19Really? Can we have a go? I mean, can we see?
0:02:19 > 0:02:21Oh, no! It's horrible.
0:02:21 > 0:02:24It goes up and down and round and round and up and over
0:02:24 > 0:02:26and down and up and round and...
0:02:26 > 0:02:28MALFUNCTIONS
0:02:28 > 0:02:31It's supposed to, silly.
0:02:31 > 0:02:34No, the problem is the rails at the top are very old,
0:02:34 > 0:02:38and aren't safe any more. My rail-checker never lies.
0:02:38 > 0:02:42We need to change them. No more rides until we do!
0:02:42 > 0:02:47- Oh, boo.- How are we going to change the rails?
0:02:47 > 0:02:50It's a bit, er, high.
0:02:51 > 0:02:56- I know a big robot who can help. - Of course! Stan Tall!
0:02:57 > 0:02:59We'll go and get him.
0:02:59 > 0:03:01Oh, thanks, you three.
0:03:01 > 0:03:05We'll stay here and make sure no-one goes on the roller-coaster.
0:03:05 > 0:03:06Let's Oki-go!
0:03:09 > 0:03:13No, sorry. No entry. Health and safety rules, you see.
0:03:17 > 0:03:22Hmmm. Where's Stan Tall? Must be around here somewhere? Stan!
0:03:22 > 0:03:26Stan Tall! Where are you?
0:03:26 > 0:03:30ROBOTIC NOISES
0:03:30 > 0:03:34Hello, Stan. I always forget how, er, tall you are.
0:03:34 > 0:03:39Stan, can you come and help us fix the roller-coaster, please?
0:03:39 > 0:03:40ROBOTIC NOISES
0:03:40 > 0:03:42OK, then. Follow us!
0:03:48 > 0:03:51- Messy, do we have to go so fast?- Yes!
0:03:51 > 0:03:55The sooner we get back to the roller-coaster, the sooner
0:03:55 > 0:04:00Stan will fix it, and the sooner we can have a roller-coaster ride!
0:04:05 > 0:04:09- Messy!- Don't forget about Stan!
0:04:09 > 0:04:10Sorry, Stan!
0:04:10 > 0:04:12ROBOTIC GROAN
0:04:12 > 0:04:13I'll slow down a bit.
0:04:17 > 0:04:19Wow, Stan! Are you OK?
0:04:19 > 0:04:21ROBOTIC NOISES
0:04:21 > 0:04:25- Oh. Can we go a bit more slowly, Messy?- OK.
0:04:25 > 0:04:28Next stop - roller-coaster!
0:04:28 > 0:04:30- Roller-coaster! - Messy!
0:04:33 > 0:04:35That was quick. Hello, Stan!
0:04:35 > 0:04:38Can you help us to take off the old rails
0:04:38 > 0:04:41and put in these new ones, please?
0:04:41 > 0:04:43ROBOTIC NOISES
0:04:45 > 0:04:50MALFUNCTIONS
0:04:50 > 0:04:53- Oh, no!- Stan, are you OK?
0:04:57 > 0:04:58Look out!
0:04:58 > 0:05:03- Stay there! Don't get up. - Stan's gone all wobbly again.
0:05:03 > 0:05:06Again! Did this happen before?
0:05:06 > 0:05:11Well, it wasn't my fault, but we were trying to get here super fast,
0:05:11 > 0:05:15and we zoomed around and around and up and down...
0:05:15 > 0:05:18OK, maybe it was a bit my fault.
0:05:18 > 0:05:23I know what's happened. Stan is having problems with his balance.
0:05:23 > 0:05:25Bal-ance? What's that?
0:05:25 > 0:05:30Balance is what keeps you standing up, and stops you from falling over
0:05:30 > 0:05:35when you walk along, or run, or turn around, or climb on something.
0:05:35 > 0:05:39But his feet are fine. His legs are fine.
0:05:39 > 0:05:41His knees are fine.
0:05:41 > 0:05:43Actually, Messy,
0:05:43 > 0:05:46your balance is controlled by something in your head.
0:05:46 > 0:05:48BOTH: Huh?
0:05:48 > 0:05:49ROBOTIC NOISES
0:05:49 > 0:05:50BEEPING
0:05:50 > 0:05:55Your head is where your brain is. Your brain is your body's computer.
0:05:55 > 0:05:59It collects information from your eyes and ears and nose
0:05:59 > 0:06:02and hands and feet, about what's going on around you,
0:06:02 > 0:06:05then tells your body what to do.
0:06:06 > 0:06:08Messy, can you stand on one leg?
0:06:08 > 0:06:11Ho-ho! I'm the best one-leg-stander ever!
0:06:11 > 0:06:14Hmmm, you are quite good, but do you know how you do it?
0:06:14 > 0:06:17Your brain tells your body how to stay upright,
0:06:17 > 0:06:20without you even having to think about it.
0:06:20 > 0:06:21OK.
0:06:21 > 0:06:24Now, try it with your eyes closed.
0:06:26 > 0:06:28I'm still standing.
0:06:28 > 0:06:33- Although your eyes help you balance, your ears do, too.- My ears?
0:06:33 > 0:06:35But you don't hear balance.
0:06:35 > 0:06:38That's right, Felix. Your ears feel it.
0:06:38 > 0:06:41Your ears are very important in keeping your balance.
0:06:41 > 0:06:43Waaaah!
0:06:43 > 0:06:48I think Stan is OK, but I need to check.
0:06:48 > 0:06:52Stan, can we have a look inside your head, please?
0:06:52 > 0:06:53ROBOTIC NOISES
0:06:53 > 0:06:57Inside his head?! It won't hurt him, will it, Zam?
0:06:57 > 0:07:00No, it won't hurt him a bit.
0:07:00 > 0:07:04Brilliant. Then, we can get back to work on the roller-coaster!
0:07:05 > 0:07:07How do we get in?
0:07:07 > 0:07:09Ah! Leave it to me.
0:07:13 > 0:07:14Well done, Felix.
0:07:14 > 0:07:17Now, Messy, remember, please don't touch anything.
0:07:17 > 0:07:19Of course!
0:07:19 > 0:07:20Ha-ha-ha!
0:07:20 > 0:07:22What?
0:07:22 > 0:07:26Whoa! This is amazing!
0:07:26 > 0:07:27- Cool!- Wow!
0:07:28 > 0:07:31Careful, now. Keep your balance.
0:07:31 > 0:07:36I still don't know how my ears are keeping me from falling over.
0:07:36 > 0:07:40Well, Messy, look, that's how!
0:07:40 > 0:07:44Your ear has a special bit inside called the inner ear.
0:07:44 > 0:07:46That's what's used for balance.
0:07:46 > 0:07:50Stan has an inner ear that works the same as yours.
0:07:50 > 0:07:55When you move up, down, or side or side, the liquid in those tubes
0:07:55 > 0:08:00moves too, and those sensors tell your brain which way you're moving.
0:08:00 > 0:08:03Then your brain tells your legs, knees, feet, toes,
0:08:03 > 0:08:06and the rest of you what to do to keep your balance.
0:08:06 > 0:08:07Oh, yes!
0:08:07 > 0:08:12When I do this, I can feel my feet and legs and knees and toes
0:08:12 > 0:08:15and everything all stopping me from falling over.
0:08:15 > 0:08:19That's because your brain is telling your body what to do.
0:08:19 > 0:08:25Well, Stan's inner ear is fine. I think you just made him dizzy.
0:08:25 > 0:08:31Diz-zee? That's a lovely word. Dizzy. Diz-zee. Dee-zee.
0:08:31 > 0:08:33What does it mean?
0:08:33 > 0:08:34BEEPING
0:08:34 > 0:08:38If you spin around too much, your inner ear can get confused,
0:08:38 > 0:08:41and sends the wrong signals to your brain.
0:08:41 > 0:08:43That's when you feel dizzy.
0:08:43 > 0:08:45Stan, you just got diz-zee.
0:08:46 > 0:08:49Messy, let's tell him to his face.
0:08:51 > 0:08:56Stan, you just got dizzy, so you're OK.
0:08:56 > 0:08:58ROBOTIC NOISES
0:08:58 > 0:09:02No more spinning, twisting, twirling, or whirling around, OK?
0:09:02 > 0:09:04ROBOTIC NOISES
0:09:04 > 0:09:08Now that you are better, Stan, let's fix that roller-coaster.
0:09:08 > 0:09:11ROBOTIC NOISES
0:09:14 > 0:09:16- Er, left a bit.- Down a bit.
0:09:16 > 0:09:18That's it!
0:09:18 > 0:09:20ROBOTIC NOISES
0:09:21 > 0:09:24Thank you for helping to fix the roller-coaster, Stan.
0:09:24 > 0:09:26It's as good as new.
0:09:26 > 0:09:29ROBOTIC NOISES
0:09:30 > 0:09:33Right, everyone. Are you sure you want to do this?
0:09:33 > 0:09:36Yes! I can't wait to get dizzy.
0:09:42 > 0:09:44Whoa...
0:09:44 > 0:09:46Waaaaaah!
0:09:48 > 0:09:50Balabalaboomboom!
0:09:52 > 0:09:54EXCITED SHOUTING AND LAUGHING
0:09:59 > 0:10:01Woo-hoo-hoo!
0:10:01 > 0:10:04Ha-ha-ha! I'm dizzy!
0:10:04 > 0:10:05Me too.
0:10:05 > 0:10:08My inner ear is confused.
0:10:08 > 0:10:10BEEPING
0:10:10 > 0:10:15That was an amazing ride! Thanks for fixing the roller-coaster, Stan.
0:10:15 > 0:10:17ROBOTIC NOISES
0:10:18 > 0:10:20Time to go. See you next time!
0:10:20 > 0:10:23- Bye!- Bye, Messy!- Bye-bye! - Bye, Messy!
0:10:25 > 0:10:29Wheeeee! Ho-ho! Phew. I feel dizzy again.
0:10:29 > 0:10:33All that spinning around has made my inner ear confused.
0:10:33 > 0:10:36Whoa! Hee-hee-hee-hee. Whoa.
0:10:36 > 0:10:40Time for a sit down. Bye, everyone!
0:10:40 > 0:10:41Balabalaboomboom!
