For no adequately explored reason I've tried various ways of physically
destroying CDs:

- Hammer on hard surface: Leaves lots of little fragments, generally still
stuck
  together by the protective coating.

- Roasting over an open fire: Produces a Salvador Dali effect until they
catch
  fire, then huge amounts of toxic smoke ("fulfilling our carbon tax quota"
  was one comment) and equally toxic-looking residue.

- Propane torch: Melts them without producing combustion products.

- Skilsaw: Melts them together at the cutting point, rest undamaged.

- Axe: Like skilsaw but without the melting effect.

- Using the propane torch and hammer to try and drop-forge a crude double-
  density CD: Messy.

Peter.
