Today I figured out a few things.... A 52 spin CD dirve has a disk edge veloicty of 823.4 kph. I went to the effort of calculating this because, after I went to the effort of strikeing the tray door of a CD drive at maximum spin with my hammer. I was able to figure out that it possible to destroy not only a whole computer, but also some very expensive lab equipment. All in far less time than it would have taken me to do the same amount of damage with my hammer. Then I figured out that my feet had required a sole edge veloicty of 38.14 kph in order to avoid blame for the mentioned explosion..... Tricky
