Mile-long zip wire opens in Wales

An old quarry is probably the last place you'd go for a thrill - until now!

Penrhyn quarry was once the world's largest slate mine. Now it's home to the longest zip wire in the northern hemisphere.

The zip wire is a mile long and can reach speeds of 100 miles an hour - that's faster than cars on the motorway!

There's also a smaller zip wire called the little zipper, in case you're not brave enough to try the big one.
