0:00:53 > 0:00:56- Wow! Everything looks so big and...
0:00:57 > 0:01:00- A giant flying monster!
0:01:01 > 0:01:04- Phew! It's not a monster. - It's just a butterfly.
0:01:05 > 0:01:09- Why does it look so big - when I put this in front of my eye?
0:01:10 > 0:01:13- And then normal size - when I put it down again?
0:01:13 > 0:01:18- Hmm. When you need to know, - go to Ocido!
0:01:31 > 0:01:33- Hiya, Sian! Hiya, Dylan!

0:01:37 > 0:01:41- Hey, what are you doing? - Where are you going? Can I come?
0:01:41 > 0:01:44- We're going exploring in the forest.
0:01:44 > 0:01:48- We'll get some great photos - with Dylan's new camera.
0:01:48 > 0:01:51- And you'll never guess - who's taking us.
0:01:51 > 0:01:52- Who? Who? Who?
0:01:52 > 0:01:56- Brethwen the explorer.
0:01:57 > 0:01:58- Who?
0:01:58 > 0:02:01- Brethwen the explorer. She's famous.
0:02:01 > 0:02:05- She was the first person ever - to see the speckled freckled frog.
0:02:06 > 0:02:08- Oh, the what now? A frog?
0:02:08 > 0:02:12- Hardly anyone's ever seen it, - but we might if Brethwen's with us.
0:02:13 > 0:02:14- Oh, hello, everyone.
0:02:15 > 0:02:17- Are you looking for the frog too?
0:02:17 > 0:02:20- We're playing hide-and-seek - with Swn...
0:02:20 > 0:02:23- ..but we've looked everywhere - on the Cloudship.
0:02:24 > 0:02:25- Swn's very good at hiding.
0:02:25 > 0:02:28- Try looking through - the binoculars again.
0:02:29 > 0:02:31- Oh! Binoculars!
0:02:31 > 0:02:35- I love, love, love, love binoculars!
0:02:35 > 0:02:37- Um, what are they?
0:02:37 > 0:02:39- Take a look.
0:02:39 > 0:02:41- Oo-o-oh!
0:02:42 > 0:02:46- They make everything - look closer than they really are.
0:02:47 > 0:02:49- How do they work?
0:02:49 > 0:02:51- Oh, hey-hey!
0:02:51 > 0:02:52- Oh, hey-hey!- - Oh, it's Swn!
0:02:53 > 0:02:57- How we see things - is all about light and lenses.
0:02:57 > 0:03:02- Light rays bounce off objects and - send pictures of them to your eye.
0:03:02 > 0:03:06- Your eye is a lens and helps - to make sure the pictures are clear.
0:03:06 > 0:03:09- Lenses can be made from glass or - plastic.
0:03:09 > 0:03:13- They're used to send - the light rays a different way...
0:03:13 > 0:03:16- ..and make things look bigger - or smaller.
0:03:16 > 0:03:21- Things like binoculars, telescopes, - magnifying glasses, all use lenses.
0:03:21 > 0:03:25- Ooh, that's what I have at home! - A magnifying glass.
0:03:26 > 0:03:28- Swn?
0:03:28 > 0:03:31- Swn?- - Oh, Swn's gone to hide again!
0:03:31 > 0:03:34- OK. We're going to find him.
0:03:34 > 0:03:37- Swn! Coming, ready or not!
0:03:38 > 0:03:41- Hello? Is anybody there?
0:03:42 > 0:03:45- Oh, dear. - I think I went the wrong way.
0:03:45 > 0:03:46- Oh, Brethwen!
0:03:46 > 0:03:48- Oh, Brethwen!- - Over here, Brethwen! Hello!
0:03:49 > 0:03:51- Over here!
0:03:51 > 0:03:53- Ah. There you are.
0:03:53 > 0:03:57- No wonder I couldn't see you. - You were hiding.
0:03:58 > 0:03:59- Huh?
0:04:00 > 0:04:03- I don't blame you - with this snake in the garden.
0:04:03 > 0:04:06- That's a hosepipe.
0:04:06 > 0:04:08- I think she's joking.
0:04:09 > 0:04:13- Oh, we're not worried - about that silly old snake.
0:04:13 > 0:04:15- Ha-ha! That's the spirit.
0:04:16 > 0:04:21- I was just the same when I was - a young girl. Just like you.
0:04:21 > 0:04:23- Huh?
0:04:25 > 0:04:31- Right. Come along, then. Best foot - forward and to the forest we go.
0:04:34 > 0:04:38- Nope. Sorry, eh, just testing.
0:04:39 > 0:04:41- Ahem. This way.
0:04:45 > 0:04:50- Now, we need to look - for little froggy clues.
0:04:50 > 0:04:54- Tracks. Footprints.
0:04:54 > 0:04:55- Brethwen!
0:04:55 > 0:04:58- Ah. Right. There you are.
0:04:59 > 0:05:02- Ha-ha-ha! You do like - this hiding game, don't you?
0:05:02 > 0:05:06- Erm... Right.
0:05:14 > 0:05:17- Here, froggy. Come to Blero.
0:05:19 > 0:05:21- Huh?
0:05:21 > 0:05:24- Here, froggy, froggy.
0:05:24 > 0:05:26- Here, froggy, froggy!
0:05:26 > 0:05:28- Froggy!
0:05:30 > 0:05:31- Erm... Oh.
0:05:35 > 0:05:37- Ah! There you are.
0:05:39 > 0:05:44- No sign of the Speckled Freckled - Frog of the Forest yet, Brethwen.
0:05:44 > 0:05:48- Where's Brethwen? - Oh, no! We've lost her!
0:05:48 > 0:05:51- How can she get lost? - She's an explorer.
0:05:51 > 0:05:56- Yes, but I don't think Brethwen - can see very well.
0:05:56 > 0:06:01- Don't you remember? She thought the - hosepipe in the garden was a snake.
0:06:01 > 0:06:03- She thought I was a little girl.
0:06:03 > 0:06:05- We have to find her.
0:06:05 > 0:06:08- We have to find her.- - She could be anywhere in the forest.
0:06:09 > 0:06:11- What would Brethwen do?
0:06:12 > 0:06:17- Hmm. She would look for clues, - like, erm, footprints!
0:06:17 > 0:06:20- Yes! Let's see if we can find hers.
0:06:20 > 0:06:21- Come on.
0:06:24 > 0:06:25- Hey, look!
0:06:25 > 0:06:29- They must be Brethwen's. Come on!
0:06:36 > 0:06:39- Brethwen! Wait!
0:06:39 > 0:06:42- Hello? Oh...!
0:06:43 > 0:06:46- Oh, thank goodness we found you, - Brethwen.
0:06:47 > 0:06:48- Sit down here.
0:06:49 > 0:06:54- Oh, thank you. I was getting worried - I'd never find my way back to you.
0:06:54 > 0:06:56- But you're a famous explorer.
0:06:56 > 0:06:58- But you're a famous explorer.- - Aye, I was.
0:06:58 > 0:07:01- But I'm not as young - as I used to be...
0:07:01 > 0:07:04- ..and my eyesight - isn't very good these days.
0:07:04 > 0:07:06- I didn't want to let you down.
0:07:06 > 0:07:08- Oh, that's alright, Brethwen.
0:07:08 > 0:07:10- Oh, that's alright, Brethwen.- - We understand.
0:07:10 > 0:07:15- Sim calling Swn, wherever you are. - We give up!
0:07:15 > 0:07:18- Stop hiding and come back.
0:07:19 > 0:07:20- It's over! You win!
0:07:21 > 0:07:23- Hey, Sim, Sam! Down here!
0:07:24 > 0:07:25- Hello!
0:07:25 > 0:07:28- Stand back, we're coming down.
0:07:29 > 0:07:31- I bet Sim and Sam could help you.
0:07:32 > 0:07:36- Hello, you three. Hello, Brethwen. - Have you seen Swn?
0:07:36 > 0:07:38- No. Sorry.
0:07:38 > 0:07:40- We'll help you look later.
0:07:40 > 0:07:43- Brethwen's having trouble - seeing things properly.
0:07:43 > 0:07:46- Could those lenses - you told us about help?
0:07:46 > 0:07:48- Well, yes. They might.
0:07:48 > 0:07:52- And not only that, - they might help us find Swn, too.
0:07:53 > 0:07:58- Ooh, if only there was some way to - show you how lenses could help.
0:08:00 > 0:08:01- Hooray.
0:08:04 > 0:08:09- Sometimes, the lenses on your eyes - don't work as well as they could.
0:08:09 > 0:08:13- The light doesn't always hit - the lens in the right way.
0:08:13 > 0:08:16- But if you put another lens - in front of the eye...
0:08:16 > 0:08:19- ..you can change the way - light hits the eye.
0:08:20 > 0:08:22- And that helps - the person to see better.
0:08:23 > 0:08:26- To figure out what type of lens - is best for each person...
0:08:27 > 0:08:28- ..you need an eye test.
0:08:30 > 0:08:34- Can you see more or less clearly - with this lens?
0:08:35 > 0:08:37- The same.
0:08:39 > 0:08:41- Oh, now! - Now that's much less blurry!
0:08:42 > 0:08:44- What about now?
0:08:44 > 0:08:46- Oh! I can see very clearly!
0:08:46 > 0:08:51- And now I can make you - a pair of glasses in the workshop.
0:08:53 > 0:08:54- Ta-da!
0:08:56 > 0:08:58- Bala-bala-boom-boom!
0:08:58 > 0:09:00- They look so cool!
0:09:00 > 0:09:02- Hooray!
0:09:05 > 0:09:09- I can see everything, perfectly!
0:09:10 > 0:09:12- Even you, little girl.
0:09:14 > 0:09:19- I can see the leaves on the trees - and those tiny froggy footprints.
0:09:21 > 0:09:23- Did you just say froggy footprints?
0:09:24 > 0:09:27- Oh, yes, I believe I did.
0:09:27 > 0:09:29- Yes! We'll find it now!
0:09:29 > 0:09:31- Here, froggy, froggy, froggy!
0:09:32 > 0:09:33- Here, froggy!
0:09:43 > 0:09:45- We just missed it.
0:09:45 > 0:09:48- Oh, well, they are quite shy.
0:09:48 > 0:09:50- And very hard to find.
0:09:51 > 0:09:54- We didn't get a picture - of the frog...
0:09:54 > 0:09:58- ..but we can still get - a photo of all of us!
0:09:58 > 0:10:00- Yes. A photo.
0:10:01 > 0:10:07- To remind me of the best exploring - day I've had for a long time.
0:10:09 > 0:10:12- Thanks to all of you - and my new spectacles.
0:10:12 > 0:10:14- Hooray.
0:10:14 > 0:10:15- Smile!
0:10:16 > 0:10:17- Hooray.
0:10:17 > 0:10:21- We got to see the frog after all.
0:10:21 > 0:10:25- I've had a brilliant day - but I've got to get back home now.
0:10:25 > 0:10:26- Bye, everyone!
0:10:27 > 0:10:28- Goodbye, Blero!
0:10:31 > 0:10:35- Lenses can make things - look bigger or clearer.
0:10:36 > 0:10:38- Even if they're really far away!
0:10:38 > 0:10:39- Bye-bye!
0:10:40 > 0:10:41- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
