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.
