I love hot tea in the winter but hate the mess the spoon can make if I don’t rinse it before putting it in the sink. This concept cup is supposed to eliminate the need for a spoon. The designer(s) of this cup have replaced the spoon with a floater and a marble that mixes your drink when you swish it around.

While this a good concept and a neat design, I wonder how well the drink will mix without giving the cup a good shake. Then there is the cleaning issue, which wasn’t discussed.
