0:00:13 > 0:00:14Hey, guys.
0:00:14 > 0:00:18Ricky here with your Tuesday Newsround.
0:00:18 > 0:00:21First up, it's the most important night for movie makers - The Oscars.
0:00:21 > 0:00:23Also called the Academy Awards, they recognise the best films
0:00:23 > 0:00:26of the year, and the nominations are out today.
0:00:26 > 0:00:34Has your favourite made the cut?
0:00:38 > 0:00:44The Oscars. Celebrating the best of Hollywood. One of the most popular
0:00:44 > 0:00:50categories is the best animation feature, and denominations are Coco,
0:00:50 > 0:00:55all about a 12-year-old Mexican boy who dreams of becoming a musician.
0:00:55 > 0:01:06It is up against D. Surprisingly, though, no nomination for Despicable
0:01:06 > 0:01:11Me three.
0:01:11 > 0:01:18Me three. Disney's Beauty and the Beast is also up for nomination.
0:01:19 > 0:01:26Harry's Styles Dunkirk has been nominated for eight awards. Star
0:01:26 > 0:01:29Wars The Last Jedi also has some nominations. We will find out who
0:01:29 > 0:01:31has won on Sunday the 4th of March.
0:01:31 > 0:01:35Tennis now and Kyle Edmunds has made it into the last four of one
0:01:35 > 0:01:37of the biggest tennis tournaments in the world.
0:01:37 > 0:01:41The British number two beat Grigor Dimitrov
0:01:41 > 0:01:49in the Australian Open and will play in a semi-final on Thursday morning.
0:01:49 > 0:01:56I am loving it right now. Just the way I'm playing. I'm 23 years old
0:01:56 > 0:02:01and this is my first grand slam semifinal. You don't do that every
0:02:01 > 0:02:04day. So I just tried to enjoy it as much as possible.
0:02:04 > 0:02:08Now, when you get hungry, do you ever feel like you just can't
0:02:08 > 0:02:10get hold of your food quick enough?
0:02:10 > 0:02:12Well, these crafty crows have figured out a way
0:02:12 > 0:02:17to let them do just that.
0:02:17 > 0:02:24It is tea-time. I fancy some spiders and some grubs. Not me, silly! I'm
0:02:24 > 0:02:29talking about the crows. But what on earth are they doing with those
0:02:29 > 0:02:34tweaks? Some plumbing? It turns out they are picking away at the fibres
0:02:34 > 0:02:38to make a sharp, lookalike instrument. It means they can stick
0:02:38 > 0:02:42it into places like tree holes to capture their prey more easily.
0:02:42 > 0:02:44Scientists have carried out an experiment with the crows and found
0:02:44 > 0:02:48that when they use these tools, they are ten times faster at getting
0:02:48 > 0:02:56their snack than using just a simple twig. Animals making tools is a
0:02:56 > 0:02:59pretty big deal. Scientists are pretty excited. There is no messing
0:02:59 > 0:03:03with these clever crows, is there? And although making tools is pretty
0:03:03 > 0:03:07unusual, they're not the only animal doing it. Chimpanzees use sticks as
0:03:07 > 0:03:11tools and these sea otters use hammers to crack open shellfish.
0:03:11 > 0:03:17Even elephants are at it, using branches to get flies of them. I'm
0:03:17 > 0:03:23impressed, but I'm still grateful for my knife and fork, to be honest.
0:03:23 > 0:03:26Next, millions of people around the world are obsessed with slime.
0:03:26 > 0:03:30But 16-year-old Alyssa is a slime superstar.
0:03:30 > 0:03:34Check this out!
0:03:34 > 0:03:38I think slam has become so popular because it is creative and it is
0:03:38 > 0:03:45interesting and it is a little different from what we usually see.
0:03:50 > 0:03:56I actually try to stick my flying making only to the weekends because
0:03:56 > 0:04:01during the week I'm really busy at school. I'd be making it for ever,
0:04:01 > 0:04:07since I was little, with my mum, sometimes in science classes. The
0:04:07 > 0:04:11basic component is your blue base and your PVA glue and then your
0:04:11 > 0:04:15activator concepts of laundry detergent. A surprising ingredient
0:04:15 > 0:04:19is shaving cream because it usually makes it super fluffy and fun to
0:04:19 > 0:04:23play with. A big thing with my page is like to have a lot of variety. I
0:04:23 > 0:04:32don't stick to one type of Slime. People may think this is crazy. I
0:04:32 > 0:04:38have some pigments and micro beads and ingredients that I buy online.
0:04:38 > 0:04:45Lotion, contact lens lotion, shaving cream. I just think that people find
0:04:45 > 0:04:51it intriguing and it's really satisfying. Satisfying is probably
0:04:51 > 0:04:57one of the biggest things people say about Slime.
0:04:57 > 0:04:59That's it from me, Newsround's back at 7.40 tomorrow.
0:04:59 > 0:05:01Don't forget to head online to check out the rest of the day's stories.
