where hundreds of school kids have been chatting live to astronaut

Tim Peake who is oribting Earth on the International Space Station.

Hello,. Welcome to the world museum here in Liverpool. Some very excited

children here who managed to put questions to Tim Peake who is live

in the International space Centre. Let's take a look at the moment when

they put their questions to him. Hello to the world museum in

Liverpool. Welcome to everyone following the cosmic classroom on

the Internet. First question is from Chloe from Liverpool. My question

is, why doesn't space have any gravity? That is a great question.

It is a little bit tricky for me to answer. We do have gravity appear.

We almost have as much as on planet Earth but we are tricking planet

Earth by travelling really fast. What an exciting day. I'm joined by

three of the children who put questions to major Tim Peake.

Matthew, Oliver, and Chloe. Were you nervous? What question did you ask?

I asked if there was a possibility of a meteor hitting the

International space Station. I was very excited and I was very relieved

that I managed to answer it. Were you nervous or excited about your

question? My question was what is your favourite experiment on board

the International space Station? Is it a once in a lifetime experience.

Not many people asked a question to a real-life astronaut up in space.

Were you happy with your answer? Yes. Chloe, I know you were a bit

nervous. How did you feel? I was excited. My question was why is

there no gravity in space. Were you happy with that? Yes. Tim Peake has

been up there for six weeks and he has inspired lots of children up

there today. Head over to the Newsround website

to see more great stuff about Tim Peake's mission,

including a spectacular snap of the UK taken from space,

and the toy doll floating around Next to a man living

in India who's built himself It's so amazing that his friends

have decided to give him Meet the man known as iron man. He

has built a bionic arm purely built from scrap metal. It looks like

something you would see in a Star Wars movie. How did he come up with

the idea? TRANSLATION: I have been obsessed with machines since

childhood. I learned electrical engineering in high school. He

spends his time fixing household electronics, like fridges, fans, and

televisions. If he can build a bionic arm out of scrap, who knows

what he will come up with yet. Next, take a look at this

eagle in the Netherlands, which is being taught to hunt

a different type of flying object. Police in the Netherlands

are training eagles and other birds to catch illegal drones in the sky

above large events or near airports. The birds are taught to treat

the drones as if they were a small Next how do you make

a waterfall flow backwards? These waterfalls on the Isle

of Mull usually tumble dramatically in to the sea,

west of Scotland. But gale force winds caused

by Storm Henry sent them flowing Now to a museum with a twist,

around 300 statues have been placed 15 metres under the sea

in the Canary Islands. The concrete statues

are moulded from real people That's all from me, Newsround's back

right here in about half an hour.
