What you're really doing when you tip over a teapot is attempting to direct a stream of water out of the spout and into a cup. The basic action is very well acknowledged in Kay Kim's kettle concept.
The designer worked with each element of an effective kettle quite thoughtfully to produce the most efficient, user-friendly and aesthetically pleasing model possible. The relationship between the handle and the nozzle proved to be a particularly interesting one when it comes to the act of pouring boiled liquid.
Kay Kim's kettle has been sculpted to make the handgrip and the spout appear as one. The curving tubular component extends from one end to the other and establishes an exact axis between the tipping motion and the mug.
