Physics and a necktie

Someone had the odd idea to try tossing a necktie in the direction of a spinning fan. Cavan's tie, to be exact. It was during BM, I was talking to Jonathan, when he suddenly pointed to something behind me. So I turned, had a look, and saw a green tie spinning away on one of the fan's blades. It was a funny sight. Everyone eventually cottoned on to what everyone was laughing and pointing out about. Pn. Kang wasn't very happy about it, however. Like, duh!

I was contemplating throwing my PJ shirt on the fan too after PJ. But then I took into consideration of the embarrassment and trouble I'd have to get through before I had my shirt back, so....Forget about it! Let some other sucker toss his clothing onto the fan.
