If you are a passionate admirer of thrill, then you certainly already went down from ArcelorMittal Orbit slide. Otherwise, we recommend that you visit the Olympic Park and thrill yourself a little.
All comers are offered rather short - it lasts only 40 sec., - but incredibly exciting descent. The 178-meter-long tunnel has 12 steep turns, loops and bends, including the narrow part through which you have to squeeze. The turn was nicknamed bettfeder, which translates from German as "mattress spring".
