Good afternoon, you're live with me, Ricky, and the water slide that's

taken over a city is on the way... Coming up: The giant water slide

that is taking over a city plus why you would be for given for thinking

you are seeing a double. It's Newsround.

But first, zookeepers say they're worried a baby monkey stolen from

its cage earlier this week might struggle to survive without the

right care and attention. Four other primates that were illegally taken

from Blackpool zoo have been returned but the youngest is still

missing. Here's Jenny with more. Cotton-top tamarins are critically

endangered, with only 6,000 left in the wild. Two females and a young

baby were taken on Tuesday night after thieves broke into the

animal's enclosure. I think it is disgusting. We have not ever had any

primates stolen from the zoo and the ones that have been taken very

endangered animals. Two male emperor tamarins were also taken Experts say

individual monkeys can fetch hundreds, even thousands, of pounds

on the black market, one of the reasons why they may have been

taken. The animals can be worth quite a lot

of money but to us the value is not important, we just wanted our

animals back. We wanted to make sure they were in a good condition.

Then on Friday a breakthrough. Lancashire Police found four of the

monkeys abandoned on a doorstep in West Yorkshire.

When I got to Halifax police station they were in small metal cages. They

looked in good condition but obviously they did look scared.

But the baby cotton-top tamarin is still missing and the zoo says being

away from the environment it was born in is worrying. Obviously we

are still trying to find out whether -- where the remaining animal is.

That baby is dependent on its mother at the moment. Police will continue

their search for the baby monkey. It's hoped he will be returned to

his family here at Blackpool Zoo very soon.

In other news: Ukraine's Prime Minister's accused Russia and its

supporters of trying to start a real war in the country.

It follows growing violence between Ukraine's army and pro-Russian

groups for control of important buildings in several towns and

cities in the East. It's all due to a split in the country between those

who want neighbouring Russia to have more influence and those who want

Ukraine to be closer to the EU. Next: Imagine if the main street

where you live could be turned into a giant water slide? Well, that's

exactly what's happened today in Bristol with a 300 foot flume built

as part of a massive art project. The BBC's Andrew Plant's been there

all day. Shooting down one of Bristol's main

streets, it is also one of the steepest in the city, closed to cars

since early this morning and converted into a giant water slide.

It is all the idea of one local artist. I suppose I am getting

people to think about the city in a new way. Imagine if slides were

installed all around it is as a way of commuting to work, wouldn't it be

fun? The key ingredient is the washing up liquid they have been

adding to the slide all morning and the more they put on, the faster

they go. It was really good. Because I am light I was ready fast. It was

really good fun. The first Sunday in every month in Bristol will see the

centre closed to traffic and there are plenty more ideas for plenty

more imaginative ways to move around.

I absolutely love it. Footy and Chelsea have a chance to

go top of the Premier League this afternoon if they beat Norwich.

Manchester City are still favourites to win the league after a vital over

Everton put them top with a game in hand yesterday. Fuham and Cardiff

were both relegated. To a scientific experiment that will

send shivers down your spine next. Twins Hugo and Ross are testing how

extreme temperatures affect the body by trekking across the Arctic in

clothing from both the modern day and 100 years ago.

Hugo and Ross are identical twins and they spent months preparing for

a very different Arctic expedition. The brothers will trek 340 miles

across the Greenland polar icecap to try and raise hundreds of thousands

of pounds for charity. The experience will be very different

for each of them. You go will be dressed in modern protective

clothing while Ross will be wearing the sort of kit used by polar

explorers 100 years ago. The brothers decided who would wear what

by flipping a coin. The experiment will allow researchers to monitor if

and how Hugo benefits from advances in modern technology and nutrition.

They began the exhausting trek earlier in the week so how is Ross

coping wearing the type of kit explorers wore many years ago? When

I stop for ten or 15 minutes I can start to slightly feel the wind but

all I have is a very thin jumper and nothing else. I have three socks in

my shoes and I need to know how they perform in this environment so I

have tripled up to make sure I do not get frostbite and I have just a

pair of trousers, mittens and a hat and a balaclava. I am very trek

should take 22 all going well, the trek should take 22 Finally if

you're looking at this and think you're seeing double, don't worry,

there's supposed to be two of them. These are the pictures from a huge

festival for twins in China. More than 1000 sets of twins attended.
