Sure, you could stand in your kitchen, glaring at your pasta water, waiting for it to boil. Boil. Boil you bastard. Or, you could relax, and let the floating Boil Buoy whistle from afar when your water's ready to go.
The Boil Buoy is deliciously simple. A miniaturized buoy that floats inside your pot, jingling its bells when the agitated seas begin to boil. You hear the bell, you know it's time to cook. Or, you could just stand there and stare at the pot. Like some kind of non-lazy chump. [Gizmodo]
