The kids got to try one version of it though, check this out:
And a Spiderman pose!
And then they got to do "The Rocket", where they guy put som extra bungys on them, pull them downwards and - released..! They went really high!
Linnea said she wanted to stay there all day! They did get a huge jump though since it was towards the end of the day, and no one else was there. Good fun!
