4 years ago London was home to the 2012 Olympics. I watched the stadium being built…and then a big twisted red metal structure alongside it. What on earth was it? What was the point of something that was so big and odd looking? But now I think it’s pure genius. The ArcelorMittal Orbit was the brain child of Anish Kapoor. He also created ‘Cloud Gate’ (aka the giant reflective Bean) in Millennium Park in Chicago, USA. Originally the Orbit was just an observation tower, but 2016 saw the introduction of the world’s longest and tallest tube slide, a collaboration with scientist and artist, Carsten Holler. The Orbit slide was born!
