Halloween, Time Travel & Gymnastics Blue Peter

Today's show is seriously scary, as we've got Naomi from Nightmares of

Nature. We are also making some scary monsters out of these socks.

Lindsey ran the marathon in them. Hello. Welcome to a spooky, scary

blue BT. It is Halloween on Saturday. We are getting excited and

dressing up the studio to look like it. Those ghostly balls are my

favourite. If you like fear, I had a lot of it in my new Blue Peter

challenge with a Olympic legend. You will see him in just a second. I got

invited to Parliament to turn back the hands on one of the best, most

famous monuments in the world. It was brilliant. I will turn back time

later. I will also be showing you sound to make -- how to make your

own sock monster. It is Halloween this weekend. What are you doing?

Are you getting dressed up and putting on something scary? Tell us

about it. Get in touch and we will try and read your e-mail out later.

Lindsey isn't here. She is in Canada. She's back next week but she

has hooked us up with the queen of all things scary when it comes to

animals. This lady hosts Nightmares of Nature. She has stared down a

jaguar, and she has swam with sharks. Please welcome Naomi

Wilkinson. Hello. I'm excited to be here. Let's talk about your third

series. It is fantastic. You have met some scary animals. Tell us

about them. I have had some scary encounters. I got in the water with

Wales sharks. It is the biggest shock in the world. -- whale sharks.

I breathed into waking cobra's mouth through a tiny bit of straw. That

was waking it up after health checks. We found this on a beach in

Pembrokeshire, it is a ragworm. I don't like it. It is quite creepy,

but it is not harmful at all. Your fear knows no bounds. Does yours? I

don't want to go there. I'm going to play a game with you. You are going

to love it. We are calling it Fear or Fake. Come and play. Step this

way, take your positions on the petrifying podium. You are such a

good presenter, Naomi. You are going to love this, not a lot. You have to

try and guess the Halloween horror I am describing to you. The first

person to buzz and get it correctly gets to nominate their opponent to

put their hand into either box A or box B. In one of the boxes is a real

scary animal. The other one is fake. Are you prepared? I am up for this,

Naomi. You are going to love it. The overall loser will have a forfeit.

Halloween horror number one. This fearsome creature has heat-seeking

vision. Bat? Incorrect. It's their snake. It is! Which box do you want

him to put his hand in? I would like him to put his hand in box A. It is

so nice not to be me for a change. Put your hand in gently. Take it

steady. Write down inside. Feel around. Fear or fake? Fear. That is

fear correct. That is corn snakes. That was a mistake! Halloween horror

number two. These creatures have no arms or legs. Another clue? A worm?

No. They act as nature's recyclers, raking down rotten animals. Another

clue? You both look clueless. They turn into flies. This is rubbish.

Maggots. Well done, it is. Which box would you like him to put his hand

in? I am thinking box B. Radzi, just to remind you, you have no idea. We

genuinely don't know what is going on. Oh, no! What is it? What is it?

Fear or fake? Oh, no! It's real! You are doing very well so far. Under

number three. It was maggots. These creatures are powerful jumpers.

Kangaroo. No, it's not. They have spikes on their abdomen which they

use as a weapon. Starfish. No. I will give you another clue. They

share their name with a popular sport. How's that? Cricket! Yes!

Well done, Radzi. Which one? Box A. No, box B. Nothing to worry about at

all, Barney. Nothing to worry about at all. I don't like that! That is

fear, without a doubt. It is, correct. Those are crickets. They

are horrible! They are actually in both boxes. Who is our ultimate

loser? Barney, sorry. Well done, Radzi. That was actually OK. Thank

you for being here. Always good to have you on the show. Don't relax

too much. He scary animals haven't gone just yet. As the ultimate

loser, Barney, you have to introduce the next part of the show holding my

friend, Charlotte, who is a tarantula. Don't drop her. Oh, my

giddy aunt! Your hands are solid as a rock. Aren't they just? If you

want to see more from Naomi, we don't, but if you do, go to the

website. Did you enjoy your extra hour in bed on Sunday? I did that,

honestly. Are you struggling to concentrate? No, I'm fine! Time is

constantly ticking, isn't it. We use it to organise our lives. It keeps

us all in sync. Sometimes it lets us know when we are late to school. If

I'm going to talk about time, I'm going to need a clock, but not just

any old clock. I've gone to see the most famous clock in the world. Oh,

yes! We've been invited to Parliament to help with a very

special task, the changing of the clocks. Taking me through each stage

in the process are the clock mechanics, Ian, Hugh and Paul. All

the work happens at the top, which means climbing 334 steps. This is

one of those times when you have two speed be filled up. I am climbing

Elisabeth tower. The name Big Ben refers to the bell. Why do we change

the clocks? To explain, we have to go into space. The earth is tilted

as it orbits the sun. In the summer, we have longer days as we are facing

the sun. In the winter, the days are short because we are facing away. A

British builder called William Willis first suggested changing the

clocks in 1907, to make the most of daylight hours. I am finally here.

This is the great clock of Westminster. Look at that! It may

not look like the clocks you have at home, but this mechanism turns the

hands on the clock face. It weighs 4.5 tonnes, the same as a fully

grown elephant! We know that Big Ben is the sound that you here, but the

bit you recognise is the clock face. We are behind it. It is massive.

Seven metres across. This is the inspection hat. We can look and make

sure no panes of glass are broken. I think we should inspect the outside

while we are here. A lovely view of London. There is the camera crew,

Hallo! We can't get the camera out there to show you what the view is

like, but I have a little camera to show you just the job. Look out

here! That is me hanging out of this massive monument in London. Isn't it

beautiful? Enough dangling out of this world famous building, I've got

a job to do. First, turning the lights off. This takes place just

after 10pm and it allows the team to change the time without anybody

outside noticing. South, west... You have switched off the lights. And we

can now switch off the -- set the clock. This is the piece of

equipment we have to use. Nice and tight. That isn't going anywhere.

That isn't going to make a noise. We Big Ben silenced, we can change the

time. Unlock it -- unlike a clock at home, this mechanism can only go

forward. We have to move it on until exactly midnight where it will be

held until real catches up. Ready? Ready. What is happening outside is,

in complete darkness, you will see the silhouette of the hands moving

round. Time flies when you're having fun. Bang on! There you have it,

midnight. The night is chosen to allow for several hours of

maintenance to take place. And one of the most important jobs, winding

the clock. Years ago, my grandma had a watch with a wheel on the site you

would wind up and the energy would give you power so it would keep

working. This doesn't have batteries so we effectively have two wind it

up. We do. You have to do 120 to make it last three days. Harder!
