From Pontus Lurcock
I was surprised that in the recent discussion covering uses for old and unwanted CDs
(Letters, 9 May, p 58), nobody seems to have mentioned
microwaving.
Simply place the offending disc in the microwave (shiny side up), turn out
the lights and switch on. Within a few seconds there’s an impressive “KZZZZAT”,
and blue lightning plays briefly across the surface of the CD. The disc’s
surface cracks in an aesthetically pleasing crazy paving/dried riverbed
pattern.
Not exactly useful, but very satisfying.
