I must confess that I have been microwaving CDs for years. It is always a good show - it looks much like it does in the picture, although I would guess that the picture's exposure was perhaps one-half second or more.
In my experience having microwaved scores of CDs in scores of microwaves over the past 20 years, the only repercussions are that (A) the CD is absolutely destroyed and (B) the event smells like burnt plastic for a few minutes afterwards.
