The first idea is a new method of stirring your tea. A ball in your cup stirs your tea as you swirl it like a fine cognac.
The second idea is a matt that glows when a teacup is placed on it. This glow slowly vanishes as the brew time goes on and disappears when the time is up.
The third idea is based on a pattern slowly appearing on a cup as the hot water is added and the pattern fully appears when the brew time is over.
