I vote "yes". This is definitely something my difficult child would have tried at that age. He always managed to get himself into strange situations that sometimes involved a rush trip to the emergency room. He had absolutely no fear at all!
Probably one of ours!! I am not a difficult child (or so I think!) but I shoved my best friend down the laundry shoot from 2nd floor to 1st floor when I was about 13. She stuck her elbows out and was stuck in the shoot until my mom got home several hours later. It still makes me laugh! Come to think of it, that was the same year we put our friends (twins) into a dryer (my friend's uncle owned the laundrymat) at the same time. It worked great until one of them got sea sick - you do the visual!!!
