Braun Bell Cup / Braun Bell Cup

Blindfold yourself and pour a glass of water without spilling it over. Ok, make this tougher,fill in exactly ¾ th cup. Tough?Yeah, that’s how hard it is for he blind people to fill in cup of be-
verages without spilling. Dipping the pinkie to anticipate the levels is ok for cold stuff, but what about scalding hot coffee! It’s has 3 indicative levels on the handle and liquid level sensors within the cup. The blind folks only need to choose their levels and keep pouring till the bell sounds.
