Hi, guys - it's Hayley here with the big stories

this Thursday afternoon.

Coming up...

Floods hit south-east England.

And the very happy Icelandic football commentator.

COMMENTATOR SCREAMS.

First - to the BIG story that you're loving on Newsround online today.

Yep, this is our Ayshah going down the world's tallest

and longest tunnel slide!

It's opening in London tomorrow in the park where the 2012

Olympics took place...

Since the Games finished, the site has been transformed and has hosted

lots of other sporting events.

But what could this huge sculpture be turned into?

A giant slide, of course.

We were first asked about it two years ago.

They said, is it possible to have a slide?

The answer is of course yes, we want to have a slide.

How did you go about doing it?

We had to track it out.

We went down some other big slides and any had to

work out how to go the right speed.

If you add in corners, as you are pushed out into the

corner that helps you go down a bit and so the corners are not just

for fun, they help control the speed on the way down.

There's only one thing for it.

I'm going to have to slide down.

But not for fun because I am a serious news journalist

so I'm going to be getting you all the facts you need

to know while I'm sliding down.

It goes round 12 times and is taller than the Statue of Liberty.

I'm going 15 miles an hour right now but

it feels so much faster.

And I can't remember any of the other facts

because I'm going way too fast!

Wait, it is 111 mes.

The things I do for Newsround.

OK, time for a quick round-up of today's other big stories.

London and south-east England have been hit by sudden floods after

heavy rain and lightning overnight.

People in this home woke up to water coming UP through their toilet.

One month's worth of rain fell overnight -

and forecasters say there's more wet weather to come.

These guys wouldn't mind a bit of rainy weather...

They're mountain chicken frogs and they're critically endangered.

Now a plan to help save them has started in the north of England.

Conservationists have created a climate-controlled home

in a shipping container at Chester Zoo and matched up frogs

in the hope they'll breed.

And some of you may have had your schools turned

into polling stations today.

It's because there's a massive vote for adults

on whether the UK should stay in, or leave, a club of countries

called the European Union.

Voting ends at 10pm - and we'll bring you the result

tomorrow on Newsround.

Next - it's on an epic journey around the world

and now Solar Impulse 2, the plane that flies with no fuel

has made it to Spain after leaving New York earlier this week.

Touching down in Seville this morning...

Solar Impulse 2 is getting closer to completing

its round-the-world trip.

The aim of the mission is to show what solar power can do.

The future is clean and it starts now.

The aircraft is powered by 17,000 solar cells that power

the motors and batteries.

The journey started in March last year in Abu Dhabi -

stopping off in countries like India, China and Japan.

From there, it flew to Hawaii - a record flight that

lasted almost five days.

But the plane damaged its batteries and had to stay

grounded for 10 months.

Then in April this year, Solar Impulse 2 took to the skies

again, stopping at different states in America.

It left New York on Monday to cross the Atlantic Ocean.

Now it's safe in Spain, the crew have to work out a route

to get back to Abu Dhabi where the adventure first began.

From solar to star - a footy star that is!

It's been confirmed that Jamie Vardy will be staying at Leicester City.

The club announced today that they'd agreed a deal with the striker -

who's in France for the Euros - to stay on for four more years.

There was talk that Vardy might leave the Foxes for Arsenal,

after the Gunners made a bid for him earlier this month.

That news will make many Leicester fans happy -

but probably not quite as happy as this Euro 2016

commentator for Iceland...

COMMENTATOR SCREAMS.

..Who erupted with joy after Iceland scored a last-minute

winner against Austria to make the knockout stage.

And guess who they're playing next - England!

That's all from the team and I for today.

Newsround's back on CBBC tomorrow morning at 7:40.

Have a great evening.
