A slide running the entire length of one of the steepest city centre streets in Europe has been turned into a massive three-lane water adventure.

The Slide on Cancer in Londonderry's Shipquay Street was organised by Cancer Research UK as a fundraiser.

The custom-built slide is open from 10.00-17:00 BST on Saturday and Sunday.

Participants launch themselves onto the slide at the top of the street and finish at Shipquay Gate in a huge "splash zone."

The slide is similar to the one used during the Bristol Festival but organisers said Derry's slide would be "bigger and better."

With a DJ and PA system to keep the spectators entertained, a number of politicians have already had their turn.

Sharon Arbuckle, fundraising manager for Cancer Research, said: "We are hugely excited to have brought this unique fundraising event to the city and we are delighted with the turnout so far.

"A total of 1,600 people have registered and donated their money to have their once-in-a-lifetime chance to slide down Shipquay Street," she said.

"People have come from all over Northern Ireland to be here which is great.

"We've also had tremendous support from local traders in Shipquay Street and Derry City Council who have bent over backwards to help us have a great day out and also raise some money for a very important cause."
