0:00:06 > 0:00:07this Thursday afternoon.
0:00:07 > 0:00:08Coming up...
0:00:08 > 0:00:12Floods hit south-east England.
0:00:12 > 0:00:14And the very happy Icelandic football commentator.
0:00:14 > 0:00:19COMMENTATOR SCREAMS.
0:00:27 > 0:00:30First - to the BIG story that you're loving on Newsround online today.
0:00:30 > 0:00:33Yep, this is our Ayshah going down the world's tallest
0:00:33 > 0:00:34and longest tunnel slide!
0:00:34 > 0:00:37It's opening in London tomorrow in the park where the 2012
0:00:37 > 0:00:42Olympics took place...
0:00:42 > 0:00:45Since the Games finished, the site has been transformed and has hosted
0:00:45 > 0:00:47lots of other sporting events.
0:00:47 > 0:00:49But what could this huge sculpture be turned into?
0:00:49 > 0:00:52A giant slide, of course.
0:00:52 > 0:00:54We were first asked about it two years ago.
0:00:54 > 0:00:57They said, is it possible to have a slide?
0:00:57 > 0:01:00The answer is of course yes, we want to have a slide.
0:01:00 > 0:01:01How did you go about doing it?
0:01:01 > 0:01:03We had to track it out.
0:01:03 > 0:01:05We went down some other big slides and any had to
0:01:05 > 0:01:07work out how to go the right speed.
0:01:07 > 0:01:10If you add in corners, as you are pushed out into the
0:01:10 > 0:01:14corner that helps you go down a bit and so the corners are not just
0:01:14 > 0:01:17for fun, they help control the speed on the way down.
0:01:17 > 0:01:18There's only one thing for it.
0:01:18 > 0:01:19I'm going to have to slide down.
0:01:19 > 0:01:22But not for fun because I am a serious news journalist
0:01:22 > 0:01:25so I'm going to be getting you all the facts you need
0:01:25 > 0:01:26to know while I'm sliding down.
0:01:26 > 0:01:30It goes round 12 times and is taller than the Statue of Liberty.
0:01:30 > 0:01:32I'm going 15 miles an hour right now but
0:01:32 > 0:01:33it feels so much faster.
0:01:33 > 0:01:35And I can't remember any of the other facts
0:01:35 > 0:01:45because I'm going way too fast!
0:01:56 > 0:01:57Wait, it is 111 mes.
0:01:57 > 0:01:59The things I do for Newsround.
0:01:59 > 0:02:02OK, time for a quick round-up of today's other big stories.
0:02:02 > 0:02:04London and south-east England have been hit by sudden floods after
0:02:04 > 0:02:05heavy rain and lightning overnight.
0:02:05 > 0:02:09People in this home woke up to water coming UP through their toilet.
0:02:09 > 0:02:10One month's worth of rain fell overnight -
0:02:10 > 0:02:18and forecasters say there's more wet weather to come.
0:02:18 > 0:02:20These guys wouldn't mind a bit of rainy weather...
0:02:20 > 0:02:22They're mountain chicken frogs and they're critically endangered.
0:02:22 > 0:02:25Now a plan to help save them has started in the north of England.
0:02:25 > 0:02:27Conservationists have created a climate-controlled home
0:02:27 > 0:02:29in a shipping container at Chester Zoo and matched up frogs
0:02:29 > 0:02:36in the hope they'll breed.
0:02:36 > 0:02:39And some of you may have had your schools turned
0:02:39 > 0:02:40into polling stations today.
0:02:40 > 0:02:42It's because there's a massive vote for adults
0:02:42 > 0:02:45on whether the UK should stay in, or leave, a club of countries
0:02:45 > 0:02:46called the European Union.
0:02:46 > 0:02:48Voting ends at 10pm - and we'll bring you the result
0:02:48 > 0:02:54tomorrow on Newsround.
0:02:54 > 0:02:57Next - it's on an epic journey around the world
0:02:57 > 0:03:00and now Solar Impulse 2, the plane that flies with no fuel
0:03:00 > 0:03:07has made it to Spain after leaving New York earlier this week.
0:03:07 > 0:03:08Touching down in Seville this morning...
0:03:08 > 0:03:10Solar Impulse 2 is getting closer to completing
0:03:10 > 0:03:11its round-the-world trip.
0:03:11 > 0:03:15The aim of the mission is to show what solar power can do.
0:03:15 > 0:03:21The future is clean and it starts now.
0:03:21 > 0:03:23The aircraft is powered by 17,000 solar cells that power
0:03:23 > 0:03:25the motors and batteries.
0:03:25 > 0:03:28The journey started in March last year in Abu Dhabi -
0:03:28 > 0:03:30stopping off in countries like India, China and Japan.
0:03:30 > 0:03:33From there, it flew to Hawaii - a record flight that
0:03:33 > 0:03:35lasted almost five days.
0:03:35 > 0:03:37But the plane damaged its batteries and had to stay
0:03:37 > 0:03:38grounded for 10 months.
0:03:38 > 0:03:41Then in April this year, Solar Impulse 2 took to the skies
0:03:41 > 0:03:43again, stopping at different states in America.
0:03:43 > 0:03:46It left New York on Monday to cross the Atlantic Ocean.
0:03:46 > 0:03:53Now it's safe in Spain, the crew have to work out a route
0:03:53 > 0:04:00to get back to Abu Dhabi where the adventure first began.
0:04:00 > 0:04:03From solar to star - a footy star that is!
0:04:03 > 0:04:06It's been confirmed that Jamie Vardy will be staying at Leicester City.
0:04:06 > 0:04:10The club announced today that they'd agreed a deal with the striker -
0:04:10 > 0:04:13who's in France for the Euros - to stay on for four more years.
0:04:13 > 0:04:16There was talk that Vardy might leave the Foxes for Arsenal,
0:04:16 > 0:04:23after the Gunners made a bid for him earlier this month.
0:04:23 > 0:04:25That news will make many Leicester fans happy -
0:04:25 > 0:04:27but probably not quite as happy as this Euro 2016
0:04:27 > 0:04:29commentator for Iceland...
0:04:29 > 0:04:32COMMENTATOR SCREAMS.
0:04:32 > 0:04:34..Who erupted with joy after Iceland scored a last-minute
