More fun facts for the inner geek in us:
CDs shatter at around 27,000 rpm, while 52x cd-roms, the fastest CD-ROM drives on the market, run at around 9,800 rpm. Just so you know, the forces on a CD spinning at 27,560 amount to a whopping 111 Joules, which is the energy needed to lift 150 lbs a distance of 7 inches. Quite a lot for the poor piece of plastic. The integrity of the foil data layer breaks down just about 10,000 rpm, so you can assume that the data on the disc is probably corrupt, and therefore unplayable.
That, and the fact that the CD is now a pile of plastic chunks.
(Does this mean I burn 150 joules every 7 inches I move?)
