In my boredom, I attempted to fold a CD in half. I think I was expecting it to bend and snap cleanly, like a credit card. Fortunately I turned my face away as a precaution, as it shattered into pieces, spreading shards of plastic and slivers of aluminium foil across my desk.
My boredom was not satiated though, so I decided now was the time to experience first hand the CD-in-microwave phenomenon.
