If you've already whizzed down the ArcelorMittal Orbit slide and you're looking for your next fix of kidult fun, look no further, because the world's biggest bouncy castle is coming to London. Well, actually it's less of a castle and more of an inflatable obstacle course, but it's a whopping 893ft long, you can bounce on it, and it looks absolutely ace.
It's been designed by a company called V-Formation, who refer to themselves as 'professional fun providers' and have dubbed their bouncy castle 'The Beast'. But don't let that put you off.
The giant bouncy castle is headed for London in 2017, when those professional fun providers will be challenging contestants to become the fastest person to complete the course, so you better start training now.
Here's what happened when we went down the ArcelorMittal Orbit slide.
