0:00:02 > 0:00:05# Bob the builder - can we fix it?
0:00:05 > 0:00:08# Bob the builder - yes, we can!
0:00:08 > 0:00:12# Scoop, Muck and Dizzy and Roley too
0:00:12 > 0:00:16# Lofty and Wendy join the crew
0:00:16 > 0:00:19# Bob and the gang have so much fun
0:00:19 > 0:00:23# Working together They get the job done
0:00:23 > 0:00:26# Bob the builder - can we fix it?
0:00:26 > 0:00:30# Bob the builder - yes, we can!
0:00:30 > 0:00:33# Pilchard and Bird, Travis and Spud
0:00:33 > 0:00:37# Playing together like good friends should
0:00:37 > 0:00:40# Bob the builder - can we fix it?
0:00:40 > 0:00:44# Bob the builder - yes, we can! #
0:00:53 > 0:00:57- Right, team. We've got a busy day. - What's the job, Bob?
0:00:57 > 0:01:02- We're building an observation tower. Look!- Wow!
0:01:02 > 0:01:05- A tower!- Ooh, it's really tall.
0:01:05 > 0:01:08- Taller than the trees. - Once visitors have been
0:01:08 > 0:01:12to the visitors centre, they can climb the tower.
0:01:12 > 0:01:17- And they'll be able to see for miles across Sunflower Valley.- Cor!
0:01:17 > 0:01:19- Like a bird?- Yes, Roley.
0:01:19 > 0:01:22It'll be a bird's eye view. Come on. Let's get to work.
0:01:33 > 0:01:36Right, team, this is where the tower is going.
0:01:36 > 0:01:38Can we build it?!
0:01:38 > 0:01:40ALL: Yes we can!
0:01:40 > 0:01:42Er, yeah, I think so.
0:01:55 > 0:01:57Good work, team!
0:01:57 > 0:02:01Roley and Muck, it's time for you to build a path
0:02:01 > 0:02:04- between the tower and the dome. - OK, Bob. On our way!
0:02:04 > 0:02:07Rock and roll!
0:02:08 > 0:02:10BIRD CHIRPS
0:02:16 > 0:02:19Oh, hi, bird. Guess what?
0:02:19 > 0:02:22Bob's building a tower. That's cool, isn't it?
0:02:22 > 0:02:26People will be able to climb up as high as you birds fly,
0:02:26 > 0:02:28- and see what you see! - BIRD CHIRPS
0:02:28 > 0:02:32Yeah, but I can't go up, cos I'm too big.
0:02:32 > 0:02:35- I'll never get to see what you do. - BIRD CHIRPS
0:02:49 > 0:02:53Maybe Lofty could lift me up to the top of the tower.
0:02:53 > 0:02:54BIRD CHIRPS
0:02:54 > 0:02:58Yes, I'm too heavy. I know, I just need some wings.
0:02:58 > 0:03:01Then I can fly up and enjoy the view!
0:03:01 > 0:03:04BIRD CHIRPS
0:03:04 > 0:03:06It's not that funny, bird.
0:03:06 > 0:03:10I'll find a way to get my bird's eye view. You'll see.
0:03:12 > 0:03:15Erm, why have you brought your telescope?
0:03:15 > 0:03:18Because I'm taking it up the tower later.
0:03:18 > 0:03:21Oh! Oh, brilliant idea!
0:03:21 > 0:03:22Why?
0:03:22 > 0:03:27The telescope has got a special lens to make things look bigger.
0:03:27 > 0:03:31It'll help me see things that are small or far away.
0:03:31 > 0:03:35Oh, wow! Like animals and birds?
0:03:35 > 0:03:37That's right, Dizzy.
0:03:44 > 0:03:47BIRD CHIRPS
0:03:47 > 0:03:51We're at the visitors centre. The digging's finished.
0:03:51 > 0:03:54We need to get the chippings for the park.
0:03:54 > 0:03:58Let's see how the tower's going on the way. Come on!
0:04:06 > 0:04:08Oh, wow!
0:04:08 > 0:04:11Look how high it is!
0:04:11 > 0:04:13- DIZZY:- Yeah, I know!
0:04:13 > 0:04:18It makes me feel all dizzy just looking up at Bob and Wendy.
0:04:18 > 0:04:19Hey, Bob, how's the view?
0:04:19 > 0:04:22It's fantastic, Roley.
0:04:22 > 0:04:24I can see all the way to Bobsville.
0:04:24 > 0:04:27Oh, oh...
0:04:27 > 0:04:30- I wish I could see it too. - Come on, Roley.
0:04:30 > 0:04:33- We'd better get on.- OK, Muck.
0:04:33 > 0:04:37Poor Roley. He really wants to see the view from up here.
0:04:37 > 0:04:42I know, but we'd never get a road roller up these steps.
0:04:47 > 0:04:52I can't go up the tower, so...
0:04:52 > 0:04:56I've got to get the view... to come down to me.
0:04:56 > 0:05:00- BIRD CHIRPS - See, bird, now you're looking
0:05:00 > 0:05:03at a machine's eye view of the world.
0:05:03 > 0:05:05BIRD CHIRPS
0:05:05 > 0:05:08- ROLEY LAUGHS - I can still see you!
0:05:08 > 0:05:10Oh, bird, that's it!
0:05:10 > 0:05:13If Lofty holds this mirror up in the air,
0:05:13 > 0:05:17I'll be able to look into it and see the view from the tower!
0:05:17 > 0:05:18BIRD CHIRPS
0:05:18 > 0:05:22Then I'll see what you see, bird! I told you I'd find a way!
0:05:23 > 0:05:25That's it, Lofty!
0:05:25 > 0:05:28Now, lift it as high as you can.
0:05:28 > 0:05:32- Oh, are you sure, Roley? - Course I am!
0:05:32 > 0:05:36When I know it works, Bob can fix a big mirror up there
0:05:36 > 0:05:41so even the people who can't climb the tower can enjoy the view.
0:05:41 > 0:05:44- Good idea!- Yeah, I'd like to see the view.- Me too!
0:05:47 > 0:05:51Oh! It's too far away! I can't see anything.
0:05:51 > 0:05:54Maybe you could use Bob's telescope.
0:05:54 > 0:05:58He said it was for seeing far away things.
0:05:58 > 0:06:00Rocking idea, Dizzy.
0:06:02 > 0:06:06Oh! My eyes are too big. If I could just...
0:06:07 > 0:06:09Uh-oh! Look out, Roley!
0:06:09 > 0:06:12Oh! Oh, no!
0:06:14 > 0:06:17Oh, please don't be broken, Bob's telescope.
0:06:17 > 0:06:19What's going on?
0:06:19 > 0:06:22I'm really sorry. I was trying to look at the mirror.
0:06:22 > 0:06:26I thought I could see the view from the tower.
0:06:26 > 0:06:29Oh, it's OK, Roley. It was an accident.
0:06:29 > 0:06:33I'm not going to come up with any more clumsy ideas.
0:06:33 > 0:06:35I'll just go back to my work.
0:06:37 > 0:06:39Oh, poor Roley.
0:06:39 > 0:06:42It was a clever idea to try and use a mirror.
0:06:42 > 0:06:46I know! I wonder if there is a way to make his idea work.
0:06:46 > 0:06:50- To use a mirror to reflect the view from the tower down there?- Yes!
0:06:50 > 0:06:54Oh! Do you know, I sort of remember something like that
0:06:54 > 0:06:58- from science lessons.- Me too, Wendy.
0:06:58 > 0:07:01BOTH: The camera obscura!
0:07:04 > 0:07:06- BIRD CHIRPS - Oh, bird.
0:07:06 > 0:07:09I really thought it was going to work.
0:07:09 > 0:07:12If only I hadn't broken the telescope.
0:07:13 > 0:07:16In the old days, they had a way of seeing an image
0:07:16 > 0:07:18- from a different place.- They did?!
0:07:18 > 0:07:23Yes, it was called a camera obscura.
0:07:23 > 0:07:26Oh yeah, camera obscura...
0:07:26 > 0:07:28What's that?
0:07:28 > 0:07:29It works like a camera.
0:07:29 > 0:07:33Light goes in and is reflected using a lens and mirror.
0:07:33 > 0:07:37Lenses and mirrors. So Roley did have the right idea.
0:07:37 > 0:07:41Yes, he did. It just needs to be dark to see the picture.
0:07:41 > 0:07:44That's what camera obscura means - dark room.
0:07:44 > 0:07:48- We've already got a mirror. - And a lens from the telescope.
0:07:48 > 0:07:51- So we just need a dark room. - That's right.
0:07:51 > 0:07:56So I want you all to help build a camera obscura to surprise Roley.
0:08:18 > 0:08:20Woo-hoo!
0:08:20 > 0:08:22It works, team!
0:08:22 > 0:08:24Time to get Roley.
0:08:25 > 0:08:28- What's going on?- It's a surprise.
0:08:28 > 0:08:30Come in here and you'll see.
0:08:32 > 0:08:38I thought you had a really clever idea with the mirror and telescope.
0:08:38 > 0:08:41- You did?- You made me realise that not everyone
0:08:41 > 0:08:46- who visits Sunflower Valley will be able to climb up the tower.- I know!
0:08:46 > 0:08:52So, by taking your idea a bit further, everyone can enjoy the view!
0:08:52 > 0:08:55- They can?- Bob to Wendy. We're ready.
0:08:58 > 0:09:00ROLEY GASPS
0:09:00 > 0:09:02- It's magic!- No, just science!
0:09:02 > 0:09:06I've used the mirror and a lens to reflect the light down,
0:09:06 > 0:09:10so you see, you were thinking along the right lines, Roley.
0:09:10 > 0:09:13It just needed to be in a dark room!
0:09:13 > 0:09:15Wow!
0:09:15 > 0:09:18And I really gave you the idea, Bob?
0:09:18 > 0:09:21- You did.- Rock and roll!
0:09:24 > 0:09:27Now that's what I call a bird's eye view!
0:09:27 > 0:09:30ROLEY LAUGHS
