You may take being able to fill a mug up easily for granted, but for the blind it’s not so easy. Without being able to see how close the level of liquid is to the top of the mug, spills can happen easily.

This Braun Bell concept mug solves that problem by playing a chime when the liquid hits one of three levels within the mug. That way, a blind person can know when their cup is filled to the level that they want. Sure, not something that most people would want or need, but for those that do I’m sure it would be great.
