It seems like business as usual when you boil water in this five-cup, silicone-and-steel teakettle ($28 at Zabar’s, 2245 Broadway, at 80th St.; 212-787-2000) — that is, until you’re ready to clean up. That’s when the magic happens, particularly for space-squeezed New Yorkers. With a flattened hand, just smush the top half of the kettle like an accordion and lower its lever-style handle, and presto, you’ve got a two-and-a-half-inch-tall vessel that slides easily into a drawer — or packs up conveniently for your next camping trip.
