0:00:25 > 0:00:27Hello, children! Where have you been?
0:00:27 > 0:00:31Hello, Curious Cat, we've just came back from playtime.
0:00:31 > 0:00:35You must be very cold out there if you have those woolly scarves on.
0:00:35 > 0:00:41Yes, it was cold out there, but the scarves kept us nice and warm.
0:00:41 > 0:00:44Woolly scarves are great for cold days,
0:00:44 > 0:00:47but have you ever wondered how your scarves were made?
0:00:47 > 0:00:50Doesn't wool come from sheep?
0:00:50 > 0:00:53Yeah! That's right, it all starts with sheep!
0:00:56 > 0:00:58Look at all these sheep.
0:00:58 > 0:01:02A lot of the sheep have long woolly coats.
0:01:02 > 0:01:03These are called fleeces.
0:01:03 > 0:01:07Once a year, the sheep need their woolly coats clipped off.
0:01:07 > 0:01:09This is called shearing.
0:01:09 > 0:01:12It's a bit like having your hair cut.
0:01:12 > 0:01:14It doesn't hurt the sheep.
0:01:14 > 0:01:20The sheep's wool has grown very long and thick - too hot for summer.
0:01:21 > 0:01:24The sheep's fleece is sheared very close to its skin
0:01:24 > 0:01:27so it all comes off in one piece.
0:01:27 > 0:01:28It doesn't hurt
0:01:28 > 0:01:33and the wool grows again to keep the sheep warm in winter.
0:01:33 > 0:01:35When the sheep have been sheared,
0:01:35 > 0:01:38the fleeces are packed ready to be sent away.
0:01:42 > 0:01:44To find out what happens next,
0:01:44 > 0:01:48you'll have to go to the wool mill, where James will show you around.
0:01:48 > 0:01:49Off you go!
0:02:05 > 0:02:09So this is where the fleeces have come from the farm,
0:02:09 > 0:02:13at this table, and this is where Pete does the sorting.
0:02:13 > 0:02:18So he basically sorts it into all the different types of wool.
0:02:18 > 0:02:19Why do you do this?
0:02:19 > 0:02:21Why do we do this?
0:02:21 > 0:02:25Well, they do this because different wools are used for different things.
0:02:25 > 0:02:29Wools are used for carpets, for rugs, scarves,
0:02:29 > 0:02:33and different types of wool will give you a different effect,
0:02:33 > 0:02:38and it will give you a different finished product.
0:02:38 > 0:02:42- Would you like to help with the sorting?- OK! Yeah!
0:02:42 > 0:02:45What I do is, when I'm pulling this, that's called a staple
0:02:45 > 0:02:48and I'm pulling it to test how long it is, and the strength.
0:02:49 > 0:02:53If it's a strong one, it'll go in the better grade.
0:02:55 > 0:02:57That's really strong!
0:02:58 > 0:03:01- I've done it, I've done one.- Yeah!
0:03:03 > 0:03:08Sorting the wool is a very important job. Make sure you're listening.
0:03:09 > 0:03:11That one's easy!
0:03:11 > 0:03:14Look at that one!
0:03:14 > 0:03:16- Like cotton wool, isn't it? - That's an easy one.
0:03:16 > 0:03:18That a Suffolk.
0:03:18 > 0:03:21That'll get used for your clothes, for your knitwear,
0:03:21 > 0:03:24because it's so soft.
0:03:24 > 0:03:27- You like the feel of that one? - Yeah!
0:03:27 > 0:03:32Come on, girls, there's a lot more to see, let's get a move on.
0:03:33 > 0:03:35These are the fleeces that have been sorted.
0:03:35 > 0:03:38This is going into carpets.
0:03:38 > 0:03:40This is a lot softer
0:03:40 > 0:03:43and will go into clothing of all different sorts.
0:03:43 > 0:03:45Why is it shiny?
0:03:45 > 0:03:48Like your hair, they are different colours, different shines,
0:03:48 > 0:03:52different textures, exactly the same with sheep.
0:03:52 > 0:03:54Why do they shave the sheep?
0:03:54 > 0:03:57They could just leave it on the sheep.
0:03:57 > 0:04:00For the health of the animal, you have to shear the wool.
0:04:00 > 0:04:05So, it has to be sheared off the sheep for its wellbeing.
0:04:05 > 0:04:07Sheep are sheared in the spring
0:04:07 > 0:04:11so they can stay nice and cool in the summer.
0:04:13 > 0:04:17The wool has now been sorted and is ready to be washed and cleaned.
0:04:17 > 0:04:19This is called scouring.
0:04:20 > 0:04:25So, what we have here, where we've just come from,
0:04:25 > 0:04:29- where you saw the wool being sorted, this is all the wool.- Yes?
0:04:29 > 0:04:32So it's all coming into here,
0:04:32 > 0:04:35and then it goes off down this line to be washed.
0:04:35 > 0:04:36So we'll walk down the line
0:04:36 > 0:04:39and we'll show you at which stages it's washed.
0:04:39 > 0:04:41- Let's go!- Come on then.
0:04:49 > 0:04:54In here, what you've got is all the grease
0:04:54 > 0:04:58and all the dirt is washed out in this bowl here.
0:04:58 > 0:05:02so it's squeezed here with rollers and it goes up to the next bath.
0:05:02 > 0:05:03It's very hot in here!
0:05:03 > 0:05:05It is very hot in here!
0:05:05 > 0:05:07My legs are sweating!
0:05:07 > 0:05:11Now, this bath here, this is where we add soap.
0:05:11 > 0:05:14So there's lots of soap in that bath,
0:05:14 > 0:05:17so it's washing all the wool, it washes all the sweat
0:05:17 > 0:05:20and everything else out of the wool in this bath
0:05:20 > 0:05:22so this has got soap in it,
0:05:22 > 0:05:25and again, squeezed, and it comes up to the next bath.
0:05:25 > 0:05:29where it's rinsed, which is what you do when you've washed your hair,
0:05:29 > 0:05:33you rinse the soap out. And the last thing after that, it's been rinsed,
0:05:33 > 0:05:38and then it goes off to the drier at the far end, the wool is then dried.
0:05:38 > 0:05:42This is where the washed wool comes to be dried.
0:05:42 > 0:05:45It looks like the biggest hairdryer ever!
0:05:50 > 0:05:52The wool you see here
0:05:52 > 0:05:56is the wool that has come from the drying that we saw earlier.
0:05:56 > 0:06:00It's put on this conveyor belt here and it goes through the conveyor belt
0:06:00 > 0:06:06and into the carding machines, which are basically very big drums
0:06:06 > 0:06:09with metal wire on them that are moving at a very high speed.
0:06:09 > 0:06:14What they do is to take all the rubbish out of the wool,
0:06:14 > 0:06:16so this is what comes out.
0:06:16 > 0:06:20You have straw, you've got grass, you've got seeds.
0:06:20 > 0:06:23There's all sorts in there that we need to take out
0:06:23 > 0:06:26so it doesn't get into the finished product.
0:06:26 > 0:06:29How they used to do carding in the old days,
0:06:29 > 0:06:35these have got wire on them, so what they do is you would put the wool on,
0:06:35 > 0:06:38you'd put one on top of the other and you'd pull them apart.
0:06:38 > 0:06:43This is how they used to do it going back many years,
0:06:43 > 0:06:44which is a very long process.
0:06:44 > 0:06:49Now, obviously there is so much wool, we have to do it by big machines.
0:06:49 > 0:06:52- It's a good job they invented machines then!- It is indeed!
0:07:14 > 0:07:16LAUGHTER
0:07:16 > 0:07:20- Cool!- I feel like diving in it! - I know!
0:07:20 > 0:07:25It was all dirty, but now it's just really clean in little bunches.
0:07:25 > 0:07:28I really feel like diving in it and swimming!
0:07:30 > 0:07:34The wool has now been washed, dried and carded.
0:07:34 > 0:07:36James has taken the girls to the spinners
0:07:36 > 0:07:39to see how it's turned into long strings of twisted wool,
0:07:39 > 0:07:41known as yarn.
0:07:42 > 0:07:46- Shall we see it running?- Yes. - OK, let's turn the machine on.
0:08:07 > 0:08:12These machines stretch the wool to make it thinner
0:08:12 > 0:08:17and then they twist the wool to make it into yarn, ready for knitting.
0:08:22 > 0:08:26So this is the wool that you've seen being spun and twisted
0:08:26 > 0:08:30and now what I'm going to do is show you the technique for finger knitting
0:08:30 > 0:08:33which you can then do and make a scarf from.
0:08:33 > 0:08:37OK, and then you put the yarn between those fingers
0:08:37 > 0:08:39and then back.
0:08:39 > 0:08:43Round, and then round your pinky finger
0:08:43 > 0:08:49and then you go back under, over, under, all the way around.
0:08:50 > 0:08:52I've started to knit a scarf!
0:08:52 > 0:08:54Yes, you've started.
0:08:54 > 0:08:59You go under, over, round your pinky, back under, over...
0:09:00 > 0:09:01Oh, I get it.
0:09:03 > 0:09:07Then that comes up and over. Up and over.
0:09:07 > 0:09:11- It's very easy when you know how to! - It is very easy when you know how.
0:09:14 > 0:09:16That's actually really good!
0:09:16 > 0:09:23Now you've seen how the wool goes from the sheep's back to a finished woolly scarf.
0:09:23 > 0:09:27Then you put it round your head, like that.
0:09:28 > 0:09:32Hello, children! How was your journey?
0:09:32 > 0:09:34Look what we've made!
0:09:34 > 0:09:36Wow, they look amazing!
0:09:36 > 0:09:40Did you find out what happens to the wool once it's been sheared?
0:09:40 > 0:09:42We went to where they sorted the fleeces out.
0:09:43 > 0:09:47First, the wool from the farms is sorted into groups
0:09:47 > 0:09:51and then it's sent to be washed and cleaned.
0:09:51 > 0:09:57The washed wool is dried in these big drying machines.
0:09:57 > 0:10:01It is then combed to get the rubbish out.
0:10:01 > 0:10:04The wool is then sent to the spinners,
0:10:04 > 0:10:06who stretch and twist the wool.
0:10:08 > 0:10:11And they turn it into yarn,
0:10:11 > 0:10:14which is what we used for our finger knitting.
0:10:14 > 0:10:16That's great!
0:10:16 > 0:10:19Those scarves will keep you nice and warm through winter.
0:10:19 > 0:10:22But now it's time to say goodbye.
0:10:22 > 0:10:23BOTH: Goodbye!
0:10:23 > 0:10:26Goodbye, children!
0:10:50 > 0:10:53Hello, children, what are you up to?
0:10:53 > 0:10:56We're putting a picture onto the glass window.
0:10:56 > 0:10:58So the light can shine through.
0:10:58 > 0:11:01Good thing you have glass windows in the classroom.
0:11:01 > 0:11:04Do you want to find out how glass is made?
0:11:04 > 0:11:06BOTH: Yeah!
0:11:06 > 0:11:08Well, glass starts off as sand...
0:11:10 > 0:11:13..a bit like the sand you might find on a beach,
0:11:13 > 0:11:19but, to make clear glass, a special sand called silica sand is used.
0:11:21 > 0:11:24This fine sand is needed because it's very pure
0:11:24 > 0:11:27and does not contain any other unwanted chemicals.
0:11:29 > 0:11:33This special sand comes from all over the world.
0:11:37 > 0:11:40To find out what happens to the sand,
0:11:40 > 0:11:44Susan will show you around the glass factory. Off you go!
0:11:53 > 0:11:56Is glass only made of sand?
0:11:56 > 0:11:59No, sand is just the main ingredient that goes into glass,
0:11:59 > 0:12:03but it also has lots of other things in it, like soda ash and limestone.
0:12:03 > 0:12:05Do you want to go have a look?
0:12:05 > 0:12:10Glass is made from sand, soda ash and limestone,
0:12:10 > 0:12:15which are three minerals that come from the ground.
0:12:15 > 0:12:19They're mixed together, then put into a very hot oven,
0:12:19 > 0:12:20called a furnace.
0:12:22 > 0:12:26So this is where all the raw ingredients are fed into the oven
0:12:26 > 0:12:29and melted, so it has to be very, very hot,
0:12:29 > 0:12:31so it goes almost like toffee.
0:12:31 > 0:12:34- Do you want to have a look?- Yes. - Yes? Right, step up on here.
0:12:40 > 0:12:43Oh, my gosh!
0:12:46 > 0:12:49That is so cool!
0:12:51 > 0:12:55Wow, it looks like popcorn!
0:12:55 > 0:12:57The furnace needs to be super hot.
0:12:57 > 0:13:02In fact, it's 1,600 degrees Celsius.
0:13:03 > 0:13:05This is what it looks like inside.
0:13:06 > 0:13:07Wow!
0:13:09 > 0:13:13So now we've seen the raw ingredients melting in the oven, almost like toffee.
0:13:13 > 0:13:18So what happens next is that this spreads across a big bath,
0:13:18 > 0:13:22which is full of liquid metal, and that gloopy substance
0:13:22 > 0:13:27floats along the top and spreads out so that it's perfectly flat.
0:13:27 > 0:13:31So we're going to go to the lab and do a little experiment so you can see what I mean.
0:13:31 > 0:13:32OK? Let's go.
0:13:34 > 0:13:38So, let's pretend that this oil is our liquid glass
0:13:38 > 0:13:41which is made up of our different raw materials.
0:13:41 > 0:13:45Remember, we've got our sand, and our soda ash here, and limestone.
0:13:45 > 0:13:50So, this is our liquid glass and this water is our liquid metal.
0:13:50 > 0:13:54So, let's see what happens when we pour the glass onto the liquid metal.
0:13:54 > 0:13:55Ooh!
0:14:03 > 0:14:06So, what's happening? Can you see what's happening?
0:14:06 > 0:14:08It's floating on top of the water.
0:14:08 > 0:14:12That's right, so the liquid glass floats on top of the liquid metal
0:14:12 > 0:14:16and doesn't mix together so the glass stays perfectly flat.
0:14:16 > 0:14:20Ah, cool! It's wicked!
0:14:20 > 0:14:22That's brilliant!
0:14:22 > 0:14:26So, just like this oil and water, the glass in the furnace
0:14:26 > 0:14:30floats on top of the liquid metal and stays completely flat.
0:14:31 > 0:14:34Now, let's see how the real glass is doing.
0:14:37 > 0:14:42So this is the first time that we can actually see the glass coming out. Do you want to have a look?
0:14:42 > 0:14:47- Stopping here...you can see it going past!- Yeah!
0:14:47 > 0:14:52- Look at that!- Cool! - It looks like see-through paper!
0:14:52 > 0:14:59At this stage, it's about half as hot as it was, and it's still quite soft.
0:14:59 > 0:15:03For the glass to get hard, it needs to cool down very slowly.
0:15:05 > 0:15:07Why is the glass cooled slowly?
0:15:07 > 0:15:11Because, if we cool it too quickly, then it could break,
0:15:11 > 0:15:15and at this stage we're also checking for any other faults in the glass
0:15:15 > 0:15:19like stress breaks, or bubbles, which are obviously no good.
0:15:20 > 0:15:24OK now, from this point, the glass is one continuous ribbon
0:15:24 > 0:15:28right back to that bath of liquid metal,
0:15:28 > 0:15:31and so the next stage is to cut it into pieces.
0:15:31 > 0:15:35This long piece of glass is far too big to be used in our homes,
0:15:35 > 0:15:38so it needs to be cut down.
0:15:45 > 0:15:49This is what it uses to cut it. It scores across the glass with these little wheels.
0:15:49 > 0:15:54That cutting bridge that's going across there makes a little line in the glass across
0:15:54 > 0:15:57and then, when it gets to these little wheels,
0:15:57 > 0:16:02it just gives it a little knock and it just breaks perfectly along that line.
0:16:02 > 0:16:05And then it moves away. Look - watch here.
0:16:05 > 0:16:08It's going to come up and break it, watch.
0:16:08 > 0:16:10Look at that!
0:16:10 > 0:16:12Wow, what a clever machine!
0:16:16 > 0:16:20If you look up ahead, you'll see the line go past.
0:16:20 > 0:16:24- It's hard to see, isn't it, because it's so clear.- Oh, yeah!- See it?
0:16:24 > 0:16:28And then it's going to go along and those wheels are just going to break it out.
0:16:28 > 0:16:33Up there. Ready? There it is, and then that piece of glass goes away!
0:16:33 > 0:16:34Cool!
0:16:37 > 0:16:40How old do you think this machine is?
0:16:40 > 0:16:43This machine, it is 11 years old.
0:16:43 > 0:16:4711. It's called Claritude.
0:16:47 > 0:16:50- That's its name.- So it's a boy?
0:16:52 > 0:16:56OK, so here we're going to see the glass being stacked onto the pack.
0:16:58 > 0:16:59Once the glass is cut,
0:16:59 > 0:17:03it travels along to a machine that uses suckers
0:17:03 > 0:17:05to gently pick up the glass and stack it,
0:17:05 > 0:17:08ready to be used in our homes.
0:17:27 > 0:17:31These big machines are used to lift up the packs of glass and move them around
0:17:31 > 0:17:36and put them on the lorries so they can be delivered to our customers.
0:17:44 > 0:17:48So, you've seen the raw ingredients go in one end and glass come out the other end.
0:17:48 > 0:17:50And that's how glass is made out of sand!
0:17:56 > 0:17:59Hello, children! How was your journey?
0:17:59 > 0:18:01The glass-making factory was great!
0:18:01 > 0:18:05We saw glass being made out of sand.
0:18:05 > 0:18:08The sand is mixed with other ingredients,
0:18:08 > 0:18:14and put into a big hot oven and heated up until it's extremely hot
0:18:14 > 0:18:16and then it all melts.
0:18:18 > 0:18:24Then it's poured onto a bath of liquid metal, but they don't mix.
0:18:25 > 0:18:30The glass floats on top. Then it goes really smooth and flat.
0:18:32 > 0:18:37They have to cool it down slowly, or it would break.
0:18:37 > 0:18:42Then the glass is cut into different sizes
0:18:42 > 0:18:46and then it is stored until it is needed.
0:18:50 > 0:18:55Well done! Now you know all about making glass!
0:18:55 > 0:18:59What en exciting journey you've had! Now it's time to say goodbye.
0:18:59 > 0:19:03- BOTH: Bye!- Goodbye, children!
0:19:27 > 0:19:30Hello, children. What are you doing?
0:19:30 > 0:19:35- We're making things out of paper. - Look, I've made a paper hat!
0:19:35 > 0:19:37Wow, that's brilliant.
0:19:37 > 0:19:42Paper is really useful for lots of things - drawing pictures,
0:19:42 > 0:19:45books to read, letters to write, and many other things.
0:19:45 > 0:19:50- But have you ever wondered how paper is made?- Doesn't it come from trees?
0:19:50 > 0:19:54Yes! That's right! Paper has been around a long, long time.
0:19:54 > 0:19:59In fact, it's been around since the ancient Egyptians!
0:20:01 > 0:20:02Look at all these trees.
0:20:04 > 0:20:07That's where it all starts, in the forest.
0:20:07 > 0:20:11This is where paper comes from, trees!
0:20:11 > 0:20:14There are young trees growing in amongst the old ones.
0:20:16 > 0:20:20If we kept cutting down all the trees, there wouldn't be any left,
0:20:20 > 0:20:23so we have to plant new ones.
0:20:24 > 0:20:27Paper is made from a mix of all types of trees.
0:20:27 > 0:20:32The trees are cut down and the branches are cut off
0:20:32 > 0:20:35and then loaded onto a truck, where they go to the paper mill.
0:20:41 > 0:20:45So you see, the trees are where the paper's journey begins.
0:20:45 > 0:20:48- Do you want to find out what happens to the logs at the paper mill? - Yes, please!
0:20:48 > 0:20:52- That would be brilliant! - Then off you go!
0:20:57 > 0:21:01Hello! My name is Liz and I work at the paper mill, and I'm going to tell you how we make paper.
0:21:01 > 0:21:03This is called the wood yard.
0:21:03 > 0:21:07This is where we store all the logs that come in straight from the forest.
0:21:07 > 0:21:09They come in on lorries.
0:21:10 > 0:21:13How many trucks deliver logs here?
0:21:13 > 0:21:16There's about 40 lorries coming in per day.
0:21:20 > 0:21:22Where are the logs going now?
0:21:22 > 0:21:26The logs all go into a big drum called the de-barker
0:21:26 > 0:21:29and it's like a great big washing machine,
0:21:29 > 0:21:33which tumbles all the logs together to take off the outer skin,
0:21:33 > 0:21:38the bark of the log, and then the logs come out of the other side and there's no bark on it.
0:21:38 > 0:21:43Why does the bark have to come off of the logs?
0:21:43 > 0:21:49Bark has to come off because you don't want to open up your comic or your magazine and see bits of wood.
0:21:50 > 0:21:55Ah! The bark is removed as it does not make good quality paper.
0:22:01 > 0:22:04These logs have had their bark removed,
0:22:04 > 0:22:07but they're still too big to make paper.
0:22:10 > 0:22:16So Liz is taking the children into the grinding room to show them what happens next.
0:22:18 > 0:22:21- What happens in the grinder? - What happens in the grinder?
0:22:21 > 0:22:25The logs that we saw getting de-barked,
0:22:25 > 0:22:28they come in and they're pushed against this rotating stone,
0:22:28 > 0:22:32which is rotating very, very fast, and the logs are pushed against it,
0:22:32 > 0:22:35which crushes the logs up into fibres.
0:22:36 > 0:22:42The grinding stones squeeze the logs so hard that it crushes them up into tiny pieces.
0:22:42 > 0:22:44These are called fibres.
0:22:44 > 0:22:46And then water is added.
0:22:47 > 0:22:49Why is water added?
0:22:49 > 0:22:53We want it to look like a porridgy mix to get the pulp.
0:22:53 > 0:22:57The pulp is what we need to go on to make the paper.
0:22:57 > 0:23:01And this is what the pulp looks like.
0:23:02 > 0:23:07Liz is going to show the children how to turn this into paper.
0:23:09 > 0:23:11We'll add the pulp in here.
0:23:12 > 0:23:17Now we're going to press this button here and that's going to mix up the water and the pulp.
0:23:19 > 0:23:21Can you hear it bubbling away?
0:23:21 > 0:23:24It's just mixing all the fibres and the water together.
0:23:24 > 0:23:26OK, that's that done.
0:23:26 > 0:23:29So now I'm going to drain away the water
0:23:29 > 0:23:31so that only the fibres are going to be left.
0:23:38 > 0:23:40And there we go.
0:23:42 > 0:23:45- Can you see all the fibres have all stuck together?- Yeah.
0:23:45 > 0:23:49Wow, it's now starting to look like paper.
0:23:50 > 0:23:52It's really wet!
0:23:52 > 0:23:55There's quite a lot of water in it yet, isn't there?
0:23:55 > 0:24:00What we have to do is put a piece of this dried paper on top of it
0:24:00 > 0:24:03to soak all the water out of it.
0:24:03 > 0:24:06What I'm going to do now is roll this,
0:24:06 > 0:24:08roll this...
0:24:08 > 0:24:11just to squeeze more of the water out.
0:24:14 > 0:24:15Peel this off.
0:24:17 > 0:24:19There we go.
0:24:19 > 0:24:22- Oh!- Woah! It feels quite smooth.
0:24:22 > 0:24:24It's not delicate now.
0:24:24 > 0:24:28Here's one we dried off earlier just to show you.
0:24:31 > 0:24:34- There we go.- It's impressive.- Yep!
0:24:34 > 0:24:36Actually holding a tree!
0:24:40 > 0:24:43This way of making paper takes a long time.
0:24:48 > 0:24:52That's why we have this great big paper-making machine.
0:25:01 > 0:25:06What happens first is that the pulp is sprayed onto a wire mesh
0:25:06 > 0:25:10and, as it moves along, the water drains away.
0:25:11 > 0:25:14Why do you have to get rid of the water?
0:25:14 > 0:25:18We have to get rid of the water so that the fibres are left on the wire mesh,
0:25:18 > 0:25:20so all the water drains through the wire,
0:25:20 > 0:25:23which is like a big sieve, and only the fibres are left on top.
0:25:28 > 0:25:32Next, the pulp is pressed by really big rollers
0:25:32 > 0:25:35that squeeze the last drop of water out.
0:25:37 > 0:25:40The last section is called the drier section,
0:25:40 > 0:25:44which is a series of heated rollers, which dries the paper out and keeps it flat.
0:25:47 > 0:25:49How many rollers does the mash go through?
0:25:49 > 0:25:54At the drier section it goes through 41 cylinders, heated cylinders,
0:25:54 > 0:25:57which squeeze out all the water and dry up the paper.
0:26:04 > 0:26:09Finally, the dried paper is rolled up, ready to leave the factory.
0:26:12 > 0:26:15Oh, look! It's coming down now!
0:26:15 > 0:26:17Why's it doing that?
0:26:17 > 0:26:20They're lowering it because it'll get sent to the warehouse
0:26:20 > 0:26:23ready to be transported straight to the printers.
0:26:38 > 0:26:43OK, you've seen all the paper process from when the logs came in at the beginning,
0:26:43 > 0:26:47- OK, so shall we have a closer look at the finished paper?- Yeah!
0:26:47 > 0:26:49OK. Here we are.
0:26:54 > 0:26:56So now we have paper.
0:26:57 > 0:27:00Can you believe that we've made that paper from the trees?
0:27:00 > 0:27:02BOTH: Woah!
0:27:02 > 0:27:04That feels really soft.
0:27:06 > 0:27:08Really amazing how you get this thin paper.
0:27:08 > 0:27:11- Quite strong as well, isn't it? - I know!
0:27:11 > 0:27:13Yeah, you can't really break it.
0:27:13 > 0:27:16It's amazing how it's so light it can actually fly.
0:27:16 > 0:27:19- It's just so beautiful!- I know.
0:27:21 > 0:27:24- Hello, children! - How was your journey?
0:27:24 > 0:27:25It was incredible!
0:27:25 > 0:27:28Look, we have paper made from trees!
0:27:28 > 0:27:32That's great! So what did you learn?
0:27:32 > 0:27:37First the paper mill takes the bark off the trees in the de-barking drum.
0:27:37 > 0:27:40It tumbles all the logs together
0:27:40 > 0:27:42and all the bark falls through a hole.
0:27:42 > 0:27:46And then they put the logs through the grinder,
0:27:46 > 0:27:50which smashes the logs up with humungous stones.
0:27:50 > 0:27:53Then they add lots of water to make pulp,
0:27:53 > 0:27:56which looks like horrible porridge!
0:27:56 > 0:27:59To get the water out of the pulp,
0:27:59 > 0:28:01they spray it onto a moving wire mesh,
0:28:01 > 0:28:04where the water drains through the bottom.
0:28:04 > 0:28:07Then the wet paper can be dried.
0:28:07 > 0:28:10Then it actually gets turned into real paper,
0:28:10 > 0:28:12the one that you use for drawing.
0:28:12 > 0:28:15That is how paper is made from trees.
0:28:16 > 0:28:20That's really good work. Well done, children! Goodbye!
0:28:20 > 0:28:23BOTH: Goodbye, Curious Cat!
0:28:23 > 0:28:26Goodbye, children!
