Use a CD to destroy inset in a
microwave and fry for 20 seconds
Test is with an AOL disk :)

Do NOT test it with a Windows CD, though:

There is that possibility.
However, it is also worth mentioning that you
should only zap it for as long as necessary as
running your microwave without a load is bad for
the magnetron and really will 'crash' it.
Short of a heavy duty shredder its a good way
of disposing of optical media as breaking them
is messy.

Scratching the TOP side of the CD with a key or a screwdriver also
works rather well.
The lower side of the CD is pure polycarbonate, and difficult to
scratch, but the upper side is only very thin, you can scratch the
reflective layer very easily.

Indeed, I recently purchased a professional disk polishing
machine - not to be confused with the cheap crap ones.
Disks which have been badly scratched and are unreadable
can be restored to factory condition, including one that
was knifed. However any scratches via the top are fatal.
But for speed, security, and lack of mess the microwave
is the final solution.
