One - Seen many types of tea kettle but I think this is one of the coolest I've ever seen in my life. Designed with both boiling and serving in mind, the one tea kettle is the winner of 2009 World Kitchen Tea-Off. Looking like a sake bottle, the one tea kettle's graphic will appear slowly when the it is placed over the stove to heat courtesy of thermochromic inks applied onto the graphics. The tea is ready once the graphics fully appear. Really like the fact that this kettle explored into the beauty of boiling. Click here for more info.
