Murray, somehow the idea of making a dish scream strikes me as slightly ... hmmm ... sadistic. I know: inanimate object. But still ...

Steve, I remember that ruler thing too! Very much a Boy Thing in our playground. It also reminds me of those ridged lengths of plastic tubing you can still get - about a meter long and you swing them at various speeds to get notes. Whoever thought of that one as something 'marketable' deserves a pat on the back! The phrase 'money for old rope' comes to mind.
