Have you ever been on one?
I know this seems really random, but I came across some videos of people playing on them in my university library (just like we used to do LOL)
They always freaked us out when we were at school, yet we just had to go over the top and under the bottom in the dark (even though the sign told you to jump off at the top and bottom floors)
For those who don't know what one is, check out the videos or check out the wikipedia page for them
