London's New Tube?

Carsten Höller’s newest creation is expected to be the longest, tallest, twistiest slide in the world. Opening in June, the tunnel slide will wrap around Anish Kapoor’s 2012 Olympic sculpture, the ArcelorMittal Orbit.

“I really like the dirtiness of it and the confusion it creates,” Höller said of the pending construction. “That you don’t really know what it is, but that it truly creates a unique experience.”

Nine years ago, Höller’s "Test Site" slides in Tate Modern Turbine Hall gauged audience’s reactions to five different slides. He used the idea of traveling through sculptures and how the unique perspective distorts the image.

“Boris Johnson – how can I put it – foisted this on the project, and kind of insisted,” Kapoor credits the mayor of London with the idea of placing the slide on the Olympic Sculpture.

The permanent attraction will stretch 584 feet, projecting participants at about 15 mph for a 40 second trip. With its two-foot diameter and .3 cm walls, this attraction is not for the claustro- or acrophobic. However, thrill seekers and art lovers, step to the front of the line.
