OK, friends, I need a gadget. Surely there is something out there that will alert me that I have forgotten to turn off the burner on the stove. Something besides the smoke alarm that I can never reach and end up knocking to the ground where it lies dormant until I get someone else to put it back up. Something that will come on before the smoke alarm. That would be good. I’ve already managed to cook the spout right off one tea kettle. Stop me before I manage new feats of inadvertent stove-top metallurgy.
