The world’s longest and tallest tunnel slide opened at the ArcelorMittal Orbit sculpture in Queen Elizabeth Olympic Park – the UK’s tallest public artwork – in London’s east last week. Standing 178 metres high, the slide wraps around the sculpture 12 times as it descends toward earth, providing a 40 second ride of speeds up to 15 kph through a series of twists and turns including a tight corkscrew section known as the ‘bettfeder’ (named after the German word for ‘bedspring’). The slide, which was designed by Belgian artist Carsten Höller at the invitation of Sir Anish Kapoor, designer of the ArcelorMittal Orbit (constructed for the 2012 Olympic Games), is open until 30th December.
