Saturday. -- we'll hope. Don't forget to watch tomorrow when

:00:00.:00:00.

Arsenal and England legend Alex Scott will be presenting.

:00:00.:00:07.

Hi, I'm Ayshah, it's Friday morning and you are live with CBBC.

:00:08.:00:10.

A lucky escape for people who were on a volcano when it erupted.

:00:11.:00:14.

And how a spider's big appetite is good for us humans.

:00:15.:00:28.

First up, to the lucky escape of a film crew and some tourists

:00:29.:00:31.

who were on Mount Etna when it erupted.

:00:32.:00:33.

This is the moment the volcano shot hot rocks,

:00:34.:00:35.

People ran away from the blast to safety and although some were hurt

:00:36.:00:46.

amazingly there were no serious injuries.

:00:47.:00:48.

BBC Reporter Rebecca Morelle was there and has spoken

:00:49.:00:50.

What happened is only really starting to sink in. Look at this,

:00:51.:01:00.

this hole was made by one of the incredibly hot pieces of volcanic

:01:01.:01:05.

rock that rained down upon us. We had a very, very narrow escape.

:01:06.:01:07.

Mount Etna is one of the world's most active volcanoes

:01:08.:01:10.

and it is usually thought to be safe to view lava flows close up

:01:11.:01:17.

but explosions like this one are unpredictable, as volcano expert

:01:18.:01:20.

Really amazing scenes at Mount Etna. It's one of your's most active

:01:21.:01:30.

volcanoes and it has been showing some fantastic eruptions recently.

:01:31.:01:35.

You can normally look at the lava flows from a reasonably close

:01:36.:01:38.

distance, but in this instance what Rebecca and the camera crew were

:01:39.:01:43.

caught up in is what we call a rootless eruption. Essentially the

:01:44.:01:46.

lava flows are coming over the water, in this case snow, and it is

:01:47.:01:53.

flashing the snow into steam. It's really dramatically expanding, and

:01:54.:01:57.

it causes an eruption of the lava flow itself. It is called a rootless

:01:58.:02:01.

because it doesn't have a vent beneath it, it's being driven by the

:02:02.:02:05.

ice and water being flashed into steam. The problem with these is

:02:06.:02:09.

that they are really rather unpredictable, so although it is

:02:10.:02:12.

great to go and view these volcanoes as close as you can safely do, at

:02:13.:02:17.

this time of year when there's lots of snow around Mount Etna, it can be

:02:18.:02:19.

a treacherous place to be. Now, to rugby union

:02:20.:02:22.

and it's the final weekend England may have already

:02:23.:02:24.

won the championship, but here's Martin to tell us why

:02:25.:02:26.

there's still plenty to play for. Six teams came to the tournament

:02:27.:02:45.

with high hopes. But then, one by one, they saw their chances of

:02:46.:02:49.

victory slip away. All except reigning champions, England. Over

:02:50.:02:54.

the last six weeks we have seen some amazing tries. And some shocking

:02:55.:03:04.

fails. Oh, my word. But the four teams looking to tie up second place

:03:05.:03:10.

are Italy, still searching for their first win, so expect Saturday's

:03:11.:03:16.

games to be as ferocious as ever. England visit Ireland in the final

:03:17.:03:20.

match. A 19th straight victory for Eddie Jones's men will not only give

:03:21.:03:25.

them a second Grand Slam in two years, but also break the record for

:03:26.:03:28.

the most wins in a row by an international team. A record

:03:29.:03:35.

currently held by none other than the mighty All Blacks. But Ireland

:03:36.:03:38.

will be doing everything in their power is to stop their fierce rivals

:03:39.:03:43.

from making history. And who were the team that brought the New

:03:44.:03:47.

Zealand winning streak to an end? England's opponent on Saturday,

:03:48.:03:48.

Ireland. But it turns out these guys

:03:49.:03:50.

have a very big appetite. And actually it's doing

:03:51.:03:55.

us all a favour. Arachnids. These creepy, Crawley

:03:56.:04:06.

beasties are many people's top phobia. But, maybe they should be

:04:07.:04:11.

known as our eight legged fairings. Hear me out on this one. A new study

:04:12.:04:17.

revealed that spiders have a pretty big appetite. Apparently they eat up

:04:18.:04:20.

to 800 million tonnes of insects every year. It might sound like they

:04:21.:04:26.

are greedy, but they are helping humans and saving us from disease

:04:27.:04:31.

carrying pests like flies and insects. Without them, the world

:04:32.:04:35.

would be swamped with bugs. So, for that, you have to give them a thumbs

:04:36.:04:43.

up. This spectacular appetite forms a very important, if rather gross,

:04:44.:04:47.

part of the food chain. So what you think about spiders now? Still

:04:48.:04:49.

scared? Me too. Just time to say Happy St Patrick's

:04:50.:04:51.

Day to everyone celebrating today. Newsround's back right

:04:52.:04:55.

here in about half an hour.
