Anish Kapoor’s ArcelorMittal Orbit Tower in London, which is already the UK’s tallest sculpture at 114 meters tall — originally built for the 2012 London Olympics — will soon be home to the world’s tallest and longest tunnel slide.  According to a report from Metro, the semi-transparent stainless steel tube slide begins its descent 80-meters above ground within the tower’s lattice structure, until spiraling five times before the final 50-meter drop. Bblur architecture and Buro Happold are tasked to design, originally envisioned by the London Legacy Development Corporation as a way to attract more visitors. The slide will open in Spring of 2016, and rides will last about 37 seconds and cost only £5 a ride.
