0:00:03 > 0:00:06Hi, I'm Ricky with all your top stories this Friday afternoon.
0:00:06 > 0:00:08Coming up on Newsround...
0:00:08 > 0:00:09Hi, Newsround, we're the Brownlee brothers.
0:00:09 > 0:00:13Keep watching to find out more about us.
0:00:13 > 0:00:17And find out why these sheep have turned the colour orange!
0:00:27 > 0:00:30They are one of the most famous pairs of siblings
0:00:30 > 0:00:31in the world of sport -
0:00:31 > 0:00:32British triathlon stars Jonny and Alistair Brownlee.
0:00:35 > 0:00:38The duo won silver and gold at the Rio Olympics last month
0:00:38 > 0:00:40and hit the headlines this week when Alistair showed
0:00:40 > 0:00:43his brotherly love by helping an exhausted Jonny over the line
0:00:43 > 0:00:48during a race in Mexico.
0:00:48 > 0:00:51Well, the Brownlees have been telling Newsround
0:00:51 > 0:00:56their childhood memories as brothers.
0:00:57 > 0:01:00Alistair and Jonny, thank you so much for coming into Newsround.
0:01:00 > 0:01:02Now, we all know that you are brothers,
0:01:02 > 0:01:07we want you to share some of your childhood memories,
0:01:07 > 0:01:10so, guys, tell us about a time when you helped each other as kids.
0:01:10 > 0:01:13Well, I think I was always helping him as a kid, really,
0:01:13 > 0:01:14being the older brother.
0:01:14 > 0:01:18I was trying to at least, and I remember one time
0:01:18 > 0:01:21we were playing in a stream, we were dam building or something,
0:01:21 > 0:01:22and he cut his finger open,
0:01:22 > 0:01:25and blood just went everywhere in the stream.
0:01:25 > 0:01:28And I held it and obviously took him back to my mum and dad,
0:01:28 > 0:01:29and he was taken to hospital.
0:01:29 > 0:01:32There it is, he has always been looking after me!
0:01:32 > 0:01:35What about you? When you have helped him out as a brother?
0:01:35 > 0:01:38I am the younger one, so he is supposed to help me out.
0:01:38 > 0:01:40Oh, that one time we cycled to school,
0:01:40 > 0:01:42I had an exam, and we swapped bikes.
0:01:42 > 0:01:44We used to cycle to school in the morning,
0:01:44 > 0:01:45one-time Alistair got a puncture,
0:01:45 > 0:01:48and he said, "Here is my bike, I've got an exam, fix it."
0:01:48 > 0:01:50It was a GCSE or something.
0:01:50 > 0:01:53I was about an hour late to school, so that is when I helped him out.
0:01:53 > 0:01:57Tell us about a time when you competed against each other as kids.
0:01:57 > 0:01:59We competed against each other all the time as kids,
0:01:59 > 0:02:01you know, everything in the garden became a massive competition,
0:02:01 > 0:02:03when we play football or badminton
0:02:03 > 0:02:05or cricket or having a race somewhere on a bike.
0:02:05 > 0:02:08We'd do all sorts of little challenges like that.
0:02:08 > 0:02:10Everything was a competition, so Monopoly, badminton,
0:02:10 > 0:02:13table tennis in the garden, even when it comes to sledging,
0:02:13 > 0:02:15the fastest one downhill, who can build the biggest snowman?
0:02:15 > 0:02:20Everything you can compete at, we competed at.
0:02:20 > 0:02:22Alistair, Jonny, thank you so much for that,
0:02:22 > 0:02:24it's been great having you on Newsround.
0:02:24 > 0:02:27That all right, thank you very much for having us. Thank you.
0:02:27 > 0:02:32Gold and silver for the Brownlee brothers!
0:02:32 > 0:02:35Go online to watch Newsround's special, Brothers And Sisters,
0:02:35 > 0:02:37to hear some incredible stories
0:02:37 > 0:02:46of sibling relationships from children all over the world.
0:02:46 > 0:02:50A British man who spent three days living as a goat in the Alps
0:02:50 > 0:02:52has won a special prize for his work.
0:02:52 > 0:02:56Thomas Thwaites had prosthetic legs made so he could walk on all fours
0:02:56 > 0:02:59and graze with other goats in the mountains.
0:02:59 > 0:03:02He said he wanted to take a break from human life.
0:03:02 > 0:03:05His research has now been given an Ig Nobel prize,
0:03:05 > 0:03:09which is awarded for funny science projects.
0:03:09 > 0:03:12From using science to some mad inventions -
0:03:12 > 0:03:14have you ever wished
0:03:14 > 0:03:16you could create a machine to make life a bit easier,
0:03:16 > 0:03:19to make you your toast or pour your glass of orange juice?
0:03:19 > 0:03:23Well, that is exactly what this man from New York in America does,
0:03:23 > 0:03:28as I've been finding out.
0:03:28 > 0:03:32He's invented a machine for just about everything.
0:03:32 > 0:03:34Joseph Herscher has been making crazy inventions
0:03:34 > 0:03:36since he was a child.
0:03:36 > 0:03:39I made my first machine when I was five years old,
0:03:39 > 0:03:41and it was a machine to store my candy.
0:03:41 > 0:03:44Obviously, very useful for a five-year-old.
0:03:44 > 0:03:47But also I noticed that it made my parents laugh,
0:03:47 > 0:03:51and that sort of encouraged me to keep making more and more machines.
0:03:51 > 0:03:54Videos of his wacky inventions have been huge hits online,
0:03:54 > 0:03:58and now he spends all day making machines.
0:03:58 > 0:04:03His contraptions are usually to help him out with everyday problems.
0:04:03 > 0:04:03In
0:04:03 > 0:04:05In the
0:04:05 > 0:04:07Often I notice when things annoy me in day-to-day life,
0:04:07 > 0:04:10"What can I do that will stop that from annoying me?"
0:04:10 > 0:04:13But Joseph doesn't just solve problems with his machines -
0:04:13 > 0:04:15he likes to have fun, too.
0:04:15 > 0:04:18The machines that I make, they're as playful as possible,
0:04:18 > 0:04:21and that doesn't make any sense, right?
0:04:21 > 0:04:23But at the same time humans are naturally playful creatures,
0:04:23 > 0:04:30and so we are drawn to the idea of a playful machine.
0:04:30 > 0:04:32Well, something that Joseph hasn't got around to inventing
0:04:32 > 0:04:34is orange sheep.
0:04:34 > 0:04:37Yes, your eyes are not tricking you - these sheep are really orange.
0:04:37 > 0:04:40A farmer in Cumbria in north-west England has decided
0:04:40 > 0:04:42to spray-paint his flock.
0:04:42 > 0:04:44Why? To put off thieves from taking them.
0:04:44 > 0:04:46The paint is not harmful,
0:04:46 > 0:04:49and the sheep have become a tourist attraction already.
0:04:49 > 0:04:53What a bright idea!
0:04:53 > 0:04:55That's all from me, Newsround is back on CBBC
0:04:55 > 0:04:58tomorrow morning at 8:55am. Have a great evening!
