May I ask how much involvement counts as participation?

Rin, for example, probably won't even touch the ferris wheel - it'd be a lot of work for her to get up onto it to unhinge it when other people in the group could do it much more easily. She'll definitely know what's going to happen, though, and she's specifically there to watch it topple into the ocean.

(For the record, I'm totally okay whether or not she gets clown'd. I'm just curious as to which would happen).
