How did Helen benefit when Mr. Graham Bell accompanied her to the World Fair?

In the summer of 1893, Helen visited the World’s fair in Chicago, escorted by Dr. Graham Bell. Helen thrived with wonder as the “marvels of invention, treasures of industry and skill and all the activities of human life actually passed under (her) finger tips.” She could visualize scenes from Cairo, India and Venice and a model of the Columbus ship, the Santa Maria. The instances of the fair and what surrounded her was communicated to her by Mr. Graham Bell. They examined the telephones. Gramophones, phonographs and other inventions in the electric building which deeply fascinated Helen. She even saw the anthropological relics that made her comprehend the operation of the progress of humankind. She touched the pieces in the exhibition and referred to them as “a sort of tangible kaleidoscope”. She was highly amused to get in touch with the larger world outside her that brought her close to the world of technology and numeric.
