Giant Slides @ Tate Modern

Visitors to Tate Modern will be able to try out five giant slides that have been unveiled at the London gallery.
The largest of the spiralling slides is more than 55m long and descends from the fifth floor of the venue. Artist Carsten Holler said his work, Test Site, was a "playground for the body and the brain". He says slides can help combat mental health problems.
Holler, 44, has constructed slides before, including one at the Prada headquarters in Milan connecting boss Miuccia Prada's office and the car park(!!). He says studies back up his belief that slides can help combat stress and depression
