Normally, when a kettle lets you know your water is boiling you'll hear a high pitched whistle. It's annoying, so you turn it off quickly. It's worked pretty well for a while now.

But Naoki Kawamoto's Musical Kettle turns that annoying whistle into song by putting a sort of flute at the spout. Instead of one high-pitched whistle, you get the song of your choice. But you should still turn the stove off right when it goes off. Just ignore the song, if you can.
