The 90m (295ft) slide was made from plastic sheets, hay bales, water and washing-up liquid and was the brainchild of artist Luke Jerram. The three hundred ticket holders who were picked from nearly 100,000 applicants took turns to hurtle down the slide watched by hundreds of spectators lining the street that was closed to traffic.
