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. | :04:56. | :04:58. |
