I happen to come across this video while looking up MTH 4501 and seen this. If I may ask, but what would cause the bell to do this in the video below? This is not my video, but I've never seen this happen. At first I thought the video was sped up or computerized, but it looks real to me. I've just never seen anything like this with a bell. It reminds me the rope came off the bell and it kept spinning.
