The 376-foot tall ArcelorMittal Orbit sculpture designed by Anish Kapoor and Cecil Balmond for the 2012 Summer Olympics in London will soon be home to the world's longest and tallest slide. The project, recently approved, will see the construction of a 591-foot long tube stretching from the tower's viewpoint to the ground. Extending 249 feet above the ground, the slide will spiral around the twoer five times and end in a 164-foot straight run to the ground. "It's about adding another attraction to the attraction," Peter Tudor, director of visitor services at Queen Elizabeth Park, told Standard. "We've already got Anish Kapoor's mirrors that turn everything upside-down, and the view. We're looking at what other experiences can we provide to engage with the sculpture."
