I went to a fair with roller coasters when last in Portland. It was great since I have now come to enjoy riding them and I am not terrified of dying. However, my pal and I were not so happy when we were done riding the worst one ever, since her iPhone fell off while we were high up in the sky and it shattered to millions of pieces.
I had totally forgotten about that experience when I came across the video below. (From my experience, please swallow whatever is in your mouth before you watch)
