Drinking water from the bell is a highly spiritual work. It is so exclusive unlike now that anybody will drink from the bell.
Now, no matter who will drink from the bell you will hear no sound. This spiritual work is for those whose fame, ora, or presence is stolen or switched, so that as they drink the water and the bell sounds again, they will be recognised and they will be known.
But nowadays people are thirsty and they put water in the bell and give them.
