:00:13. > :00:17.how you can get a waterfall to flow backwards!
:00:18. > :00:22.The eagle trained to take down drones.
:00:23. > :00:27.where hundreds of school kids have been chatting live to astronaut
:00:28. > :00:30.Tim Peake who is oribting Earth on the International Space Station.
:00:31. > :00:49.Hello,. Welcome to the world museum here in Liverpool. Some very excited
:00:50. > :00:57.children here who managed to put questions to Tim Peake who is live
:00:58. > :00:59.in the International space Centre. Let's take a look at the moment when
:01:00. > :01:13.they put their questions to him. Hello to the world museum in
:01:14. > :01:17.Liverpool. Welcome to everyone following the cosmic classroom on
:01:18. > :01:23.the Internet. First question is from Chloe from Liverpool. My question
:01:24. > :01:29.is, why doesn't space have any gravity? That is a great question.
:01:30. > :01:36.It is a little bit tricky for me to answer. We do have gravity appear.
:01:37. > :01:43.We almost have as much as on planet Earth but we are tricking planet
:01:44. > :01:48.Earth by travelling really fast. What an exciting day. I'm joined by
:01:49. > :01:53.three of the children who put questions to major Tim Peake.
:01:54. > :02:02.Matthew, Oliver, and Chloe. Were you nervous? What question did you ask?
:02:03. > :02:06.I asked if there was a possibility of a meteor hitting the
:02:07. > :02:11.International space Station. I was very excited and I was very relieved
:02:12. > :02:18.that I managed to answer it. Were you nervous or excited about your
:02:19. > :02:21.question? My question was what is your favourite experiment on board
:02:22. > :02:28.the International space Station? Is it a once in a lifetime experience.
:02:29. > :02:33.Not many people asked a question to a real-life astronaut up in space.
:02:34. > :02:42.Were you happy with your answer? Yes. Chloe, I know you were a bit
:02:43. > :02:47.nervous. How did you feel? I was excited. My question was why is
:02:48. > :02:56.there no gravity in space. Were you happy with that? Yes. Tim Peake has
:02:57. > :02:57.been up there for six weeks and he has inspired lots of children up
:02:58. > :03:02.there today. Head over to the Newsround website
:03:03. > :03:05.to see more great stuff about Tim Peake's mission,
:03:06. > :03:07.including a spectacular snap of the UK taken from space,
:03:08. > :03:10.and the toy doll floating around Next to a man living
:03:11. > :03:14.in India who's built himself It's so amazing that his friends
:03:15. > :03:36.have decided to give him Meet the man known as iron man. He
:03:37. > :03:41.has built a bionic arm purely built from scrap metal. It looks like
:03:42. > :03:48.something you would see in a Star Wars movie. How did he come up with
:03:49. > :03:51.the idea? TRANSLATION: I have been obsessed with machines since
:03:52. > :03:58.childhood. I learned electrical engineering in high school. He
:03:59. > :04:04.spends his time fixing household electronics, like fridges, fans, and
:04:05. > :04:06.televisions. If he can build a bionic arm out of scrap, who knows
:04:07. > :04:13.what he will come up with yet. Next, take a look at this
:04:14. > :04:15.eagle in the Netherlands, which is being taught to hunt
:04:16. > :04:18.a different type of flying object. Police in the Netherlands
:04:19. > :04:20.are training eagles and other birds to catch illegal drones in the sky
:04:21. > :04:23.above large events or near airports. The birds are taught to treat
:04:24. > :04:27.the drones as if they were a small Next how do you make
:04:28. > :04:30.a waterfall flow backwards? These waterfalls on the Isle
:04:31. > :04:35.of Mull usually tumble dramatically in to the sea,
:04:36. > :04:38.west of Scotland. But gale force winds caused
:04:39. > :04:40.by Storm Henry sent them flowing Now to a museum with a twist,
:04:41. > :04:47.around 300 statues have been placed 15 metres under the sea
:04:48. > :04:49.in the Canary Islands. The concrete statues
:04:50. > :05:00.are moulded from real people That's all from me, Newsround's back
:05:01. > :05:02.right here in about half an hour.
