15° cup / cup

15° cup

It is a cup designed for the blind. There is a limit for the blind to make sure whether the cup is filled. To solve this problem, we start from the gravity of the cup when pouring water into it. When the cup is empty, it is slant which can make the blind know whether there is water in the cup. However, when the cup is filled with water, the gravity of the cup changes and the cup becomes upright. At the same time, the vertical cup raps on the table and makes a clicking sound. The blind hear the knocking and know the cup is already full.
