ON 18 MARCH 1970, a former Japanese princess stood at the center of a cavernous domed structure on the outskirts of Osaka. With a small crowd of dignitaries, artists, engineers, and business executives looking on, she gracefully cut a ribbon that tethered a large red balloon to a ceremonial Shinto altar. Rumbles of thunder rolled out from speakers hidden in the ceiling. As the balloon slowly floated upward, it appeared to meet itself in mid-air, reflecting off the massive spherical mirror that covered the walls and ceiling.

大日本：艺术、科技和百事可乐如何合作，然后在 1970 年的世界博览会上发生冲突

1970 年 3 月 18 日，一位前日本公主站在大阪郊区的一个巨大圆顶结构的中心。在一小群政要、艺术家、工程师和企业高管的注视下，她优雅地剪下了一条丝带，将一个大红色气球系在神道祭坛上。隆隆的雷声从隐藏在天花板中的扬声器中传出。随着气球慢慢向上漂浮，它似乎在半空中相遇，反射出覆盖墙壁和天花板的巨大球面镜。
