Appliance Acoustic Sessions

Not all the appliances in my kitchen are always plugged in. Not all of them are even out of their cupboards. It sometimes happens that I see one on a worktop, yawn, switch it on, turn to another task... and nothing happens. This can result in unacceptable delays to the delivery of Mrs [pertinax]'s early morning tea.

So, this idea is for kitchen appliances with a built-in clockwork musical box. When the appliance *is* properly connected to the mains, the musical box draws power to wind itself up. When the appliance is switched "on" while *not* connected to the mains, there is no electrical effect, but there is a mechanical effect, namely, to start the musical box. The musical box will then play something brief and to the point, which will remind the dopey user that the thing is not plugged in.
