Regular cup / Public Design

Blind people are also willing to live like normal one and fit into the world. I don’t want to be treated as a disabled person psychologically.
This design focuses on drinking. When blind people get water alone, the cup can remind them whether the water is over or not. Meanwhile, the top of the cup will expand, which can give blind enough time to take the cup away.
when the surface of water reaches the pleated construction, the construction will expand, the more water is, the larger it will be.
