If you're a thrill seeker you're gonna want to book tickets to London for June 24, 2016, as the Carsten Höller-designed tunnel slide, set to be the longest in the world, will debut at the ArcelorMittal Orbit. Those lucky enough to enjoy the ride will be able to take in a 40-second trip down the ArcelorMittal, orbiting the structure twelve times and observing panoramic views of London's cityscape. Watch the video above for a cool behind-the-scenes look at the slide and scroll down for some awesome images. England, here we come!
